Improved Occupational Performance of Young Adults with a Physical Disability After a Vocational Rehabilitation Intervention (Article)

2013-04-29T00:00:00Z

Purpose The purpose of this study was to investigate into more detail how occupational performance of participants of a 1-year multidisciplinary vocational rehabilitation intervention changed over time, using a broad focus on three areas of occupational performance, addressing work, as well as self-care and leisure. In addition, we explored differences between employed and unemployed persons. Methods In a pre-post-intervention design, changes in occupational performance, addressing work, self-care and leisure, were evaluated using the Canadian Occupational Performance Measure (COPM) and the Occupational Performance History Interview (OPHI-II). Results Eleven young adults (median 22 years) with physical disabilities participated. Post-intervention, participants experienced fewer problems and showed improved occupational performance in work, as well as self-care and leisure, and improved satisfaction with performance. Participants also showed improved occupational identity and occupational competence, and total scores on OPHI-II. Participants who did not achieve employment did not differ in demographic characteristics. They experienced problems in all three areas of occupational performance at pre-intervention, and more difficulty in interacting in occupational settings (environment). Post-intervention, their levels of occupational identity, competence and settings were similar to those of employed persons. Conclusions Participants showed improved occupational performance after the intervention. The goal of employment and the broad integrated approach of the intervention seemed to motivate participants to resolve problems in work, as well as self-care and leisure. Unemployed persons faced problems in all three areas of occupational performance at start. Although they seemed to catch up during the intervention, they did not achieve employment within 1 year.

The influence of ergonomic devices on mechanical load during patient handling activities in nursing homes (Article)

2012-07-01T00:00:00Z

Mechanical load during patient handling activities is an important risk factor for low back pain among nursing personnel. The aims of this study were to describe required and actual use of ergonomic devices during patient handling activities and to assess the influence of these ergonomic devices on mechanical load during patient handling activities. For each patient, based on national guidelines, it was recorded which specific ergonomic devices were required during distinct patient handling activities, defined by transferring a patient, providing personal care, repositioning patients in the bed, and putting on and taking off anti-embolism stockings. During real-time observations over ~60 h among 186 nurses on 735 separate patient handling activities in 17 nursing homes, it was established whether ergonomic devices were actually used. Mechanical load was assessed through observations of frequency and duration of a flexed or rotated trunk >30° and frequency of pushing, pulling, lifting or carrying requiring forces <100 N, between 100 and 230 N, and >230 N from start to end of each separate patient handling activity. The number of patients and nurses per ward and the ratio of nurses per patient were used as ward characteristics with potential influence on mechanical load. A mixed-effect model for repeated measurements was used to determine the influence of ergonomic devices and ward characteristics on mechanical load. Use of ergonomic devices was required according to national guidelines in 520 of 735 (71%) separate patient handling activities, and actual use was observed in 357 of 520 (69%) patient handling activities. A favourable ratio of nurses per patient was associated with a decreased duration of time spent in awkward back postures during handling anti-embolism stocking (43%), patient transfers (33%), and personal care of patients (24%) and also frequency of manually lifting patients (33%). Use of lifting devices was associated with a lower frequency of forces exerted (64%), adjustable bed and shower chairs with a shorter duration of awkward back postures (38%), and an anti-embolism stockings slide with a lower frequency of forces exerted (95%). In wards in nursing homes with a higher number of staff less awkward back postures as well as forceful lifting were observed during patient handling activities. The use of ergonomic devices was high and associated with less forceful movements and awkward back postures. Both aspects will most likely contribute to the prevention of low back pain among nurses.

Course and prognosis of recovery for chronic non-specific low back pain: Design, therapy program and baseline data of a prospective cohort study (Article)

2011-11-03T00:00:00Z

Background: There has been increasing focus on factors predicting the development of chronic musculoskeletal disorders. For patients already experiencing chronic non-specific low back pain it is also relevant to investigate which prognostic factors predict recovery. We present the design of a cohort study that aims to determine the course and prognostic factors for recovery in patients with chronic non-specific low back pain. Methods/Design. All participating patients were recruited (Jan 2003-Dec 2008) from the same rehabilitation centre and were evaluated by means of (postal) questionnaires and physical examinations at baseline, during the 2-month therapy program, and at 5 and 12 months after start of therapy. The therapy protocol at the rehabilitation centre used a bio-psychosocial approach to stimulate patients to adopt adequate (movement) behaviour aimed at physical and functional recovery. The program is part of regular care and consists of 16 sessions of 3 hours each, over an 8-week period (in total 48 hours), followed by a 3-month self-management program. The primary outcomes are low back pain intensity, disability, quality of life, patient's global perceived effect of recovery, and participation in work. Baseline characteristics include information on socio-demographics, low back pain, employment status, and additional clinical items status such as fatigue, duration of activities, and fear of kinesiophobia. Prognostic variables are determined for recovery at short-term (5 months) and long-term (12 months) follow-up after start of therapy. Discussion. In a routine clinical setting it is important to provide patients suffering from chronic non-specific low back pain with adequate information about the prognosis of their complaint.

Psychosocial factors predicted nonrecovery in both specific and nonspecific diagnoses at arm, neck, and shoulder (Article)

2010-12-01T00:00:00Z

Objectives: To evaluate the differences in predictors of nonrecovery between patients with a specific diagnosis at arm, neck, and/or shoulder, vs. patients with a nonspecific diagnosis in general practice at 6 months after the first consultation. Study Design and Setting: New consulters with nontraumatic arm, neck, or shoulder complaints entered the cohort. Patient, complaint, and physical, psychosocial, and work characteristics were evaluated as possible predictors. Logistic regression analyses were conducted for the specific and nonspecific groups separately. Results: At 6 months, 38% (n = 298) of the specific-group members and 49% (n = 249) of the nonspecific-group members reported nonrecovery. Univariately, similar variables were related in both groups, although their strength sometimes differed. Multivariately, duration of complaints was predictive of nonrecovery in both groups. Other predictors in the specific group were as follows: more somatization, low social support, older age, high body mass index, and unemployment. In the nonspecific group, the predictors were as follows: musculoskeletal comorbidity, recurrent complaint, poor perceived general health, multiple-region complaints, and high level of kinesiophobia. Conclusion: At 6 months, nonrecovery was reported more frequently in the group of patients with a nonspecific diagnosis. The predictive value of psychosocial factors on nonrecovery is at least of equal importance in patients with a specific diagnosis compared with patients with a nonspecific diagnosis.

Individual and organisational determinants of use of ergonomic devices in healthcare (Article)

2010-11-23T00:00:00Z

(CS/IPC): 0.4%/2.7%, day 4 (2.1%/6.1%), day 7 (2.5%/7.9%), day 14 (4.7%/7.3%), and day 90 (1.0%/3.3%) from baseline (preoperative situation). On days 1, 4, and 7 there was a significant difference in leg circumference between the two treatment groups. Conclusions: Edema following femoropopliteal bypass surgery occurs in all patients. For the prevention and treatment of that edema the use of a class I CS proved superior to treatment with IPC. The use of CS remains the recommended practice following femoropopliteal bypass surgery.

Management decisions in nontraumatic complaints of arm, neck, and shoulder in general practice (Article)

2009-09-01T00:00:00Z

OBJECTIVE: We wanted to evaluate associations between diagnosis and characteristics of the patient, complaint, and general practitioner (GP), as well as 6 common management decisions, in patients with nontraumatic arm, neck, and shoulder complaints at the time of the first consultation with their physician. METHODS: We undertook an observational cohort study set in 21 Dutch general practices, including 682 patients with nontraumatic complaints of arm, neck, and shoulder. The outcome measure was application (yes/no) of a specific management option: watchful waiting, additional diagnostic tests, prescription of medication, corticosteroid injection, referral for physiotherapy, and referral for medical specialist care. RESULTS: Separate multilevel analyses showed that overall, the diagnostic category, having long duration of complaints, and reporting many functional limitations were most frequently associated with the choice of a management option. For watchful waiting, only complaint variables played a role (long duration of complaints, high complaint severity, many functional limitations, recurrent complaint). All these variables were negatively associated with watchful waiting. When opting for 1 of the 5 other management options, several physician characteristics played a role as well. Less clinical experience was associated with additional diagnostic tests and referral to a medical specialist. GPs working in a solo practice more frequently referred to a medical specialist. GPs working in a rural area more frequently referred for physiotherapy. Female GPs prescribed medication less frequently. Physicians with special interest in musculoskeletal complaints gave corticosteroid injections more frequently. CONCLUSIONS: Diagnostic category, long duration of complaints, and high functional limitations were key variables in management decisions with these complaints. In addition, several physician characteristics played a role as well.

Determinants of implementation of primary preventive interventions on patient handling in healthcare: a systematic review. (Article)

2009-06-06T00:00:00Z

OBJECTIVE: This systematic review aims (1) to identify barriers and facilitators during implementation of primary preventive interventions on patient handling in healthcare, and (2) to assess their influence on the effectiveness of these interventions. METHODS: PubMed and Web of Science were searched from January 1988 to July 2007. Study inclusion criteria included evaluation of a primary preventive intervention on patient handling, quantitative assessment of the effect of the intervention on physical load or musculoskeletal disorders or sick leave, and information on barriers or facilitators in the implementation of the intervention. 19 studies were included, comprising engineering (n = 10), personal (n = 6) and multiple interventions (n = 3). Barriers and facilitators were classified into individual and environmental categories of factors that hampered or enhanced the appropriate implementation of the intervention. RESULTS: 16 individual and 45 environmental barriers and facilitators were identified. The most important environmental categories were "convenience and easy accessibility" (56%), "supportive management climate" (18%) and "patient-related factors" (11%). An important individual category was motivation (63%). None of the studies quantified their impact on effectiveness nor on compliance and adherence to the intervention. CONCLUSION: Various factors may influence the appropriate implementation of primary preventive interventions, but their impact on the effectiveness of the interventions was not evaluated. Since barriers in implementation are often acknowledged as the cause of the ineffectiveness of patient handling devices, there is a clear need to quantify the influence of these barriers on the effectiveness of primary preventive interventions in healthcare.

Incidence of non-traumatic complaints of arm, neck and shoulder in general practice (Article)

2008-10-01T00:00:00Z

Incidence densities in primary care are often based on disease or region-specific code registration (e.g. 'epicondylitis', 'shoulder symptom') according to the International Classification of Primary Care (ICPC). Few estimates are available on arm, neck and shoulder complaints. Unknown, is the proportion missed due to registration with a non-region-specific code (e.g. 'muscle pain'). Therefore, we estimated the incidence in non-traumatic arm, neck and shoulder complaints in the age-group 18-64 years, and determined the contribution of non-specific codes to the total figure. In this prospective registration study, 21 general practitioners (GPs) from 13 Dutch general practices classified and registered patient's symptoms and diagnoses according to ICPC at each consultation during 12 consecutive months. Incidence densities were calculated. The incidence density was 97.4/1000 person-years (95% CI: 91.2-103.7). This results in 147 (95% CI: 138-157) incident cases/year for an average-sized GP-practice (2350 patients). Main contributors were: shoulder (L92, L08) and neck complaints (L01, L83). Of all incident consultations, 23% were registered with non-region-specific codes, mainly 'other musculoskeletal disease' (L99). Non-traumatic complaints of arm, neck and shoulder are frequently consulted for in Dutch primary care. When estimating morbidity in primary care, based on diagnostic codes, one should be aware of possible underestimation of morbidity and corresponding workload, when excluding codes not specific for that region or disease.

Management in non-traumatic arm, neck and shoulder complaints: differences between diagnostic groups (Article)

2008-09-01T00:00:00Z

Arm, neck and/or shoulder complaints are common in western societies. In the Netherlands, general practice guidelines are issued on shoulder pain and epicondylitis only. Little is known about actual management of the total range of diagnoses. The objectives of the study are: to determine management in patients consulting the GP with a new episode of non-traumatic arm neck and shoulder complaints up to 6 months after the first consultation. To evaluate differences in management between patients with specific diagnoses versus non-specific diagnoses and between specific diagnostic groups. In a prospective cohort study in general practice. We recruited 682 eligible patients. Data on diagnosis, management, patient- and complaint-characteristics were collected. Co-occurrence of treatment options was presented in scaled rectangles. After 6 months, additional diagnostic tests had been performed in 18% of the patients, mainly radiographic examination (14%). Further, 49% had been referred for physiotherapy and 12% to the medical specialist. Patients with specific diagnoses were more frequently referred for specialist treatment, and patients with non-specific diagnoses for physiotherapy. Corticosteroid injections (17%) were mainly applied specific diagnoses (e.g. impingement syndrome, frozen shoulder, carpal tunnel and M. Quervain). Frequencies of prescribed medication (51%) did not differ between specific and non-specific diagnoses. In 19% of the patients no referral, prescribed analgesics or injection was applied. Braces (4%) were mainly prescribed in epicondylitis. Overall, management most frequently consisted of prescribed analgesics and referral for physiotherapy. Specific and non-specific diagnostic subgroups differed in the frequency corticosteroid injections were applied, and referrals to physiotherapy and to a medical specialist.

Interventions for treating the radial tunnel syndrome: a systematic review of observational studies (Article)

2008-01-01T00:00:00Z

PURPOSE: For some disorders, such as radial tunnel syndrome (RTS), no randomized controlled trials and controlled clinical trials are available. To gain insight into the effectiveness of conservative and surgical interventions for treating RTS, we systematically reviewed all available observational studies on treatment of RTS. Although the validity of case series is inferior to that of controlled trials, the case series might provide valuable data about the efficacy of treatment options. METHODS: A literature search and additional reference checking resulted in 21 eligible case series for this review. Based on previous checklists, we constructed a new quality assessment and rating system to analyze the included case series. The methodological quality was assessed, and data extraction was performed. Studies with less than 50% of the maximum points on the methodological quality assessment were considered inadequate and were excluded from the analysis. To summarize the results according to the rating system for the strength of the scientific evidence for these case series, we introduced 4 levels: (1) tendency, (2) slight tendency, (3) conflicting tendency, and (4) no tendency. RESULTS: After the methodological quality assessment, 6 articles were included in the final analysis. They all reported on surgical treatment. CONCLUSIONS: There is a tendency that surgical decompression of the radial tunnel might be effective in patients with RTS. The effectiveness of conservative treatments for RTS is unknown because, for most treatments, no studies were available. Additional high-quality controlled studies are needed to assess the level of conclusive evidence for surgical treatment and also to evaluate conservative treatments for RTS. For this, we recommend a multicenter, randomized clinical trial. Due to the lack of a clear protocol for diagnosing RTS, a reliable and valid diagnostic tool should be developed. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Kinesiophobia in patients with non-traumatic arm, neck and shoulder complaints: a prospective cohort study in general practice (Article)

2007-11-01T00:00:00Z

BACKGROUND: Complaints of arm, neck and shoulder are common in Western societies. Of those consulting a general practitioner (GP) with non-traumatic arm, neck or shoulder complaints, about 50% do not recover within 6 months.Kinesiophobia (also known as fear of movement/(re)injury) may also play a role in these complaints, as it may lead to avoidance behaviour resulting in hypervigilance to bodily sensations, followed by disability, disuse and depression. However, in relation to arm, neck and shoulder complaints little is known about kinesiophobia and its associated variables.Therefore this study aimed to: describe the degree of kinesiophobia in patients with non-traumatic complaints of arm, neck and shoulder in general practice; to determine whether mean scores of kinesiophobia change over time in non-recovered patients; and to evaluate variables associated with kinesiophobia at baseline. METHODS: In this prospective cohort study set in general practice, consulters with a first or new episode of non-traumatic arm, neck or shoulder complaints (aged 18-64 years) entered the cohort. Baseline data were collected on kinesiophobia using the Tampa Scale for Kinesiophobia, the 13-item adjusted version: TSK-AV, and on patient-, complaint-, and psychosocial variables using self-administered questionnaires. The mean TSK-AV score was calculated. In non-recovered patients the follow-up TSK-AV scores at 6 and 12 months were analyzed with the general linear mixed model. Variables associated with kinesiophobia at baseline were evaluated using multivariate linear regression analyses. RESULTS: The mean TSK-AV score at baseline was 24.8 [SD: 6.2]. Among non-recovered patients the mean TSK-AV score at baseline was 26.1 [SD: 6.6], which remained unchanged over 12- months follow-up period. The strongest associations with kinesiophobia were catastrophizing, disability, and comorbidity of musculoskeletal complaints. Additionally, having a shoulder complaint, low social support, high somatization and high distress contributed to the kinesiophobia score. CONCLUSION: The mean TSK-AV score in our population seems comparable to those in other populations in primary care.In patients who did not recover during the 12- month follow-up, the degree of kinesiophobia remained unchanged during this time period.The variables associated with kinesiophobia at baseline appear to be in line with the fear-avoidance model.

Multidisciplinary consensus on the terminology and classification of complaints of the arm, neck and/or shoulder (Article)

2007-05-01T00:00:00Z

BACKGROUND: There is no universally accepted way of labelling or defining upper-extremity musculoskeletal disorders. A variety of names are used and many different classification systems have been introduced. OBJECTIVE: To agree on an "unambiguous language" concerning the terminology and classification that can be used by all relevant medical and paramedical disciplines in the Netherlands. METHODS: A Delphi consensus strategy was initiated. The outcomes of a multidisciplinary conference were used as a starting point. In total, 47 experts in the field of upper-extremity musculoskeletal disorders were delegated by 11 medical and paramedical professional associations to form the expert panel for the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis and a feedback report. RESULTS: After three Delphi rounds, consensus was achieved. The experts reported the consensus in a model. This so-called CANS model describes the term, definition and classification of complaints of arm, neck and/or shoulder (CANS) and helps professionals to classify patients unambiguously. CANS is defined as "musculoskeletal complaints of arm, neck and/or shoulder not caused by acute trauma or by any systemic disease". The experts classified 23 disorders as specific CANS, because they were judged as diagnosable disorders. All other complaints were called non-specific CANS. In addition, the experts defined "alert symptoms" on the top of the model. CONCLUSIONS: The use of the CANS model can increase accurate and meaningful communication among healthcare workers, and may also have a positive influence on the quality of scientific research, by enabling comparison of data of different studies.

Prognostic indicators for non-recovery of non-traumatic complaints at arm, neck and shoulder in general practice--6 months follow-up (Article)

2007-01-01T00:00:00Z

OBJECTIVES: To identify predictors of non-recovery in non-traumatic complaints at the arm, neck and shoulder in general practice 6 months after the first consultation. METHODS: A prospective cohort study was set in 21 Dutch general practices. Consulters with a first or new episode of non-traumatic arm, neck or shoulder complaints and age 18 through 64 yrs entered the cohort. Complaint, patient, physical, psychosocial and work characteristics were investigated as possible predictors of non-recovery at 6 months using multiple logistic regression analyses (backward Wald). RESULTS: At 6 months, 46% of the total population (n = 612) and 42% of the working subpopulation (n = 473) still reported complaints. Complaint characteristics (long duration of the complaint before consultation, recurrent complaint, musculoskeletal comorbidity and complaint mainly located at wrist or hand) were most predictive of non-recovery followed by psychosocial characteristics (more somatization and experiencing less social support). Having a specific diagnosis was associated with recovery. In the working subpopulation, the same variables were predictors of non-recovery. Additionally, low supervisory support was associated with non-recovery. The models correctly classified 72-75% of the patients (explained variance 0.27-0.28). CONCLUSIONS: Besides questions on complaint characteristics, information on somatization and support can help a general practitioner to recognize patients at risk of persistent complaints.

Qualitative evaluation of a form for standardized information exchange between orthopedic surgeons and occupational physicians (Article)

2006-11-02T00:00:00Z

BACKGROUND: Both occupational physicians and orthopedic surgeons can be involved in the management of work relevant musculoskeletal disorders. These physicians hardly communicate with each other and this might lead to different advice to the patient. Therefore, we evaluated a standardized information exchange form for the exchange of relevant information between the orthopedic surgeon and the occupational physician. The main goals of this qualitative study are to evaluate whether the form improved information exchange, whether the form gave relevant information, and to generate ideas to further improve this information exchange. METHODS: The information exchange form was developed in two consensus meetings with five orthopedic surgeons and five occupational physicians. To evaluate the information exchange form, a qualitative evaluation was set up. Structured telephone interviews were undertaken with the patients, interviews with the physicians were face-to-face and semi-structured, based on a topic list. These interviews were recorded and literally transcribed. Each interview was analyzed separately in Atlas-Ti. RESULTS: The form was used for 8 patients, 7 patients agreed to participate in the qualitative evaluation. All three orthopedic surgeons involved and three of the six involved occupational physicians agreed to be interviewed. The form was transferred to 4 occupational physicians, the other 3 patients recovered before they visited the occupational physician. The information on the form was regarded to be useful. All orthopedic surgeons agreed that the occupational physician should take the initiative. Most physicians felt that the form should not be filled out for each patient visiting an orthopedic surgeon, but only for those patients who do not recover as expected. Orthopedic surgeons suggested that a copy of the medical information provided to the general practitioner could also be provided to occupational physicians. CONCLUSION: The information exchange form was regarded to be useful and could be used in practice. The occupational physician should take the initiative for using this form and most physicians felt the information should only be exchanged for patients who do not recover as expected. That means that the advantage of giving information early in the treatment is lost.

Interventions for treating the posterior interosseus nerve syndrome: a systematic review of observational studies (Article)

2006-06-01T00:00:00Z

For the posterior interosseus nerve syndrome (PINS), no randomised controlled trials or controlled clinical trials about the effectiveness of interventions are available; only case series can be found. Although the validity of case series is inferior to controlled trials, they may provide valuable data about the efficacy of treatment options. Therefore, we systematically reviewed all available observational studies on treatment of PINS. A literature search and additional reference checking was done. On the basis of previous checklists, we constructed a quality assessment and rating system to analyse the included case series. Studies with less than 50% of the maximum points on the methodological quality assessment were excluded from the analysis. The results are summarised according to a rating system for the strength of the scientific evidence. Six eligible case series for this review were found. After the data extraction and methodological quality assessment, two higher quality studies that evaluated the effectiveness of surgical decompression of the PIN were included in the final analysis. There is a tendency for the effectiveness of surgical decompression of the PIN in patients with PINS. The effectiveness of a conservative treatment for PINS is unknown because no higher quality studies are available. Additional high-quality controlled studies are needed to assess the level of 'conclusive evidence' for surgical treatment. There is also a need for high-quality controlled trials into the effectiveness of conservative treatments for PINS.

Treatment of impingement syndrome: a systematic review of the effects on functional limitations and return to work (Article)

2006-03-01T00:00:00Z

The goal of this systematic review is to evaluate the effectiveness of different treatments for impingement syndrome and rotator cuff tear on the improvement in functional limitations and concomitant duration of sick leave. A systematic search for clinical trials or controlled studies was conducted with the following text words: should*, rotator cuff, impingement, work, sick leave, disabilit*, function*. Nineteen articles were included in this review. For functional limitations, there is strong evidence that extracorporeal shock-wave therapy is not effective, moderate evidence that exercise combined with manual therapy is more effective than exercise alone, that ultrasound is not effective, and that open and arthroscopic acromioplasty are equally effective on the long term. For all other interventions there is only limited evidence. We found many studies using range of motion and pain as outcome measures but functional limitations were less often used as an outcome measure in this type of research. Duration of sick leave was seldom included as an outcome measure.

High incidence and recurrence of shoulder and neck pain in nursing home employees was demonstrated during a 2-year follow-up (Article)

2005-04-01T00:00:00Z

OBJECTIVE: This study describes the course of shoulder and neck complaints in a working population over time. STUDY DESIGN AND SETTING: Questionnaires were administered on neck and shoulder complaints over 3 consecutive years. RESULTS: We observed 12-month incidence rates for neck and shoulder complaints of 16% to 18%, 12-month prevalence rates roughly twice as high, and 12-month recurrence rates approximately twice the prevalence rates. Each year, medical care was sought by 21% to 38% of the subjects with neck or shoulder pain, and 13% to 21% were absent from work. Although at the population level the occurrence of neck and shoulder complaints remained constant, the course of complaints within individuals demonstrated a strong episodic nature of neck and shoulder pain. Results from this study suggest that neck and shoulder complaints for most subjects run a recurrent course characterized by a strong variation in occurrence and a self-limiting course. CONCLUSION: These findings suggest that clinical trials should have a sufficiently long follow-up period to demonstrate sustainability of the therapeutic results.

Does this patient have an instability of the shoulder or a labrum lesion? (Article)

2004-10-27T00:00:00Z

CONTEXT: History taking and clinical tests are commonly used to diagnose shoulder pain. Unclear is whether tests and history accurately diagnose instability or intra-articular pathology (IAP). OBJECTIVE: To analyze the accuracy of clinical tests and history taking for shoulder instability or IAP. DATA SOURCES: Relevant studies identified through PubMed, EMBASE, CINAHL, and bibliographies of known primary and review articles. STUDY SELECTION: Studies comparing the performance of history items or physical examination with a reference standard were included. Studies on fibromyalgia, fractures, or systemic disorders were excluded. Of 1449 articles, 35 were eligible, and 17 were selected. DATA EXTRACTION: Data were extracted on study population, clinical tests, reference tests, and outcome. The studies' methodological quality (patient spectrum, verification, blinding, and replication) was assessed with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) checklist. DATA SYNTHESIS: Six tests showed positive likelihood ratios (LRs) and confidence intervals (CIs). Tests favoring the diagnosis for establishing instability included: relocation (LR, 6.5; 95% CI, 3.0-14.0) and anterior release (LR, 8.3; 95% CI, 3.6-19). Tests showing promise for establishing labral lesions included: the biceps load I and II (LR, 29; 95% CI, 7.3-115.0 and LR, 26; 95% CI, 8.6-80.0), respectively, pain provocation of Mimori (LR, 7.2; 95% CI, 1.6-32.0), and internal rotation resistance strength (LR, 25; 95% CI, 8.1-76.0). The apprehension, clunk, release, load and shift, and sulcus sign tests proved less useful. Results should be cautiously interpreted because studies were completed in select populations in orthopedic practice, mostly assessed by the test designers, and evaluated in single studies only. No accuracy studies were found for history taking or for clinical tests in primary care. CONCLUSIONS: Shoulder complaints are frequently recurrent. Instability might cause some of these complaints. Best evidence supports the value of the relocation and anterior release tests. Symptoms related to IAP (labral tears) remain unclear. Most promising for establishing labral tears are currently the biceps load I and II, pain provocation of Mimori, and the internal rotation resistance strength tests.

Work-related risk factors for the incidence and recurrence of shoulder and neck complaints among nursing-home and elderly-care workers (Article)

2004-08-01T00:00:00Z

OBJECTIVES: This study assessed the differences and similarities in the incidence and recurrence of shoulder and neck complaints with respect to work-related physical, psychosocial, and personal risk factors. METHODS: A prospective cohort study was carried out among 769 workers of nursing homes and homes for the elderly. At baseline, a questionnaire was used to collect data on personal characteristics, physical workload, psychosocial workload, and the presence of shoulder and neck complaints. After 1 and 2 years, follow-up data were collected on shoulder and neck complaints. Generalized estimation equations were used for analyzing risk factors for the participants with at least one follow-up measurement available (N=556, 72%). RESULTS: In the multivariate model, adjusted for age and gender, obesity [odds ratio (OR) 2.12, 95% confidence interval (95%CI) 1.23-3.65] was related to the incidence of shoulder complaints. The incidence of neck complaints was increased for obesity (OR 1.81, 95% CI 1.07-3.05), work in awkward postures (OR 1.76, 95% CI 1.11-2.78), and poor or fair general health (OR 1.53, 95% CI 1.02-2.31). The recurrence of both shoulder and neck complaints was associated with chronic complaints at baseline (shoulder: OR 1.91, 95% 1.36-2.67; neck: OR 1.71, 95% 1.14-2.55) but not with work-related risk factors. CONCLUSIONS: The results suggest that there are differences in risk factors for the incidence and recurrence of shoulder and neck complaints.

Haplotype analysis of three polymorphisms of the COL2A1 gene and associations with generalised radiological osteoarthritis (Article)

1999-01-01T00:00:00Z

It was investigated whether radiographic osteoarthritis (ROA) is associated with specific haplotypes of the COL2A1 gene. Radiographs of knees, hips, hands, and spine were scored for the presence of ROA in subjects of 55-70 years from a population-based cohort study, the Rotterdam study. Cases had ROA in 3 or more joint groups; controls, from the same population, had ROA in less than 3 joint groups. Allele frequencies of 3 dimorphisms (HaeIII, HindIII, MaeII) and a VNTR polymorphism of the COL2A1 gene were determined. The VNTR allele 14R2 and the HindIII polymorphism showed a significant association. Haplotype analysis of the HaeIII, HindIII and VNTR polymorphisms showed that a specific haplotype (1-2-14R2) is strongly associated with ROA in 3 or more joint groups (OR = 5.3, 95% CI 2.3-12.7). Our results suggest that a specific haplotype of the COL2A1 locus may predispose to generalised ROA.

A genetic association study of the IGF-1 gene and radiological osteoarthritis in a population-based cohort study (the Rotterdam Study) (Article)

OBJECTIVE: A genetic association study was performed to investigate whether radiographical osteoarthritis (ROA) was associated with specific genotypes of the insulin-like growth factor I (IGF-1) gene. METHODS: Subjects aged 55-65 years were selected from a population-based study of which ROA at the knee, hip, spine, and hand was assessed. Genotypes were determined of a polymorphism in the promoter region of the IGF-1 gene. RESULTS: The IGF-1 locus was significantly associated with the presence of ROA (over-all adjusted OR for heterozygous subjects = 1.9, 95% CI 1.2, 3.1 and for homozygous subjects 3.6, 95% CI 0.8, 16.2). CONCLUSION: These results suggest that variation at the IGF-1 locus is associated with ROA development and may play a part in ROA pathogenesis. To confirm these findings replication in another population-based sample is needed.
