Shoulder disorders in general practice: Incidence, patient characteristics, and management

Objectives-To study the incidence and management of intrinsic shoulder disorders in Dutch general practice, and to evaluate which patient characteristics are associated with specific diagnostic categories. Methods-In 11 general practices (35 150 registered patients) all consultations concerning shoulder complaints were registered during a period of one year. Patients with an intrinsic shoulder disorder who had not consulted their general practitioner for the complaint during the preceding year (incident cases) were asked to participate in an observational study. Participants completed a questionnaire regarding the nature and severity of their complaints. The general practitioners recorded data on diagnosis and therapy. Results-The cumulative incidence of shoulder complaints in general practice was estimated to be ll2/1000 patients/year (95% confidence limits 10.1 to 12.3). Rotator cuff tendinitis was the most frequently recorded disorder (29%). There were 349 incident cases enrolled in the observational study. Patient characteristics showed small variations between different diagnostic categories. Age, duration ofsymptoms, precipitating cause and restriction ofmovement seemed to be discriminating factors. Twenty two percent of all participants received injections during the first consultation; most (85%) were diagnosed as having bursitis. The majority of patients with tendinitis (53%) were referred for physiotherapy. Conclusion-With respect to diagnosis and treatment, the practitioners generally appeared to follow the guidelines issued by the Dutch College of General Practitioners. Although the patient characteristics of specific disorders showed some similarities with the clinical pictures described in the literature, further research is required to demonstrate whether the proposed syndromes indeed constitute separate disorders with a different underlying pathology, requiring different treatment strategies

Quadriceps muscle strength and voluntary activation after polio

Quadriceps strength, maximal anatomical cross-sectional area (CSA), maximal voluntary activation (MVA), and maximal relaxation rate (MRR) were studied in 48 subjects with a past history of polio, 26 with and 22 without postpoliomyelitis syndrome (PPS), and in 13 control subjects. It was also investigated whether, apart from CSA, MVA and MRR were determinants of muscle strength. Polio subjects had significantly less strength, CSA, and MRR in the more-affected quadriceps than control subjects. MVA was reduced in 18 polio subjects and normal in all controls. PIPS subjects differed from non-PPS subjects only in that the MVA of the more-affected quadriceps was significantly lower. Both CSA and MVA were found to be associated with muscle strength. Quadriceps strength in polio subjects was dependent not only on muscle mass, but also on the ability to activate the muscles. Since impaired activation was more pronounced in PIPS subjects, the new muscle weakness and functional decline in PPS may be due not only to a gradual loss of muscle fibers, but also to an increasing inability to activate the muscle

Beyond disability: perceived participation in people with a chronic disabling condition

Objective: To describe the impact of a chronic disabling condition on participation and to identify variables that may explain perceived restrictions in participation. Study design: Cross-sectional. Setting: People were recruited from the outpatient clinics of two rehabilitation centres and the rehabilitation department of an academic hospital. Subjects: One hundred and twenty-six people from five diagnostic groups (neuromuscular disease, rheumatoid arthritis, spinal cord injury, stroke, fibromyalgia) participated in the study. Method: The IPA (impact on Participation and Autonomy) questionnaire was used to describe perceived participation. Explanatory variables were studied in terms of sociodemographic factors and health status variables. Results: Some restrictions in participation seem comparable among diagnostic groups, others are specific to one or two groups. People with stroke, rheumatoid arthritis or fibromyalgia perceived more restrictions in participation than people with spinal cord injury or neuromuscular disorders. Emotional distress was the most important factor contributing to restrictions in participation. Conclusions: Perceived participation remains a complex concept in which many factors are involved. To make a contribution to meaningful participation of people with a chronic disabling condition, rehabilitation treatment should address physical, social, emotional and environmental aspect

Shoulder contracture and osseous deformity in obstetrical brachial plexus injuries

The purposes of this study were to determine the prevalence of and the association between shoulder contracture and osseous deformity in a cohort of children with an obstetrical brachial plexus injury and to identify the risk factors for these complications. In a retrospective cohort study, all children with an obstetrical brachial plexus injury who had been born between January 1991 and January 1998 at one academic medical center and all those with the same diagnosis who had been born elsewhere during the same period and were referred to the medical center within six weeks after delivery were evaluated at fixed time-intervals by one examiner. The patients underwent a final orthopaedic, neurological, and radiographic examination at a mean age of 3.7 years (range, one to seven years). Shoulder contracture was defined as a decrease in the passive range of motion in one or more directions compared with the range on the unaffected side. Osseous deformity was defined as a nonspherical humeral head or an abnormal glenoid. The prevalence of a shoulder contracture of >10 degrees was 56% (twenty-nine of fifty-two patients), and the prevalence of an osseous deformity was 33% (sixteen of forty-eight patients with complete radiographic follow-up). In the children in whom complete neurological recovery was delayed (i.e., recovery was more than three weeks after birth), the prevalence of shoulder contracture was 54% (thirteen of twenty-four patients) and the prevalence of osseous deformity was 26% (six of twenty-three patients). A strong association was noted between shoulder contracture and osseous deformity (p = 0.004). Directly after birth, the presence of a clavicular fracture was the only factor that was associated (p = 0.016) with the development of an osseous deformity (but not with a shoulder contracture). At a later stage, speed and extent of neurological recovery were related to shoulder contracture and osseous deformity. An asymmetric appearance was noticed in children who had a contracture, including those who had complete neurological recovery. The prevalence of shoulder contracture and osseous deformity in children with obstetrical brachial plexus injury was high, even in those with complete neurological recovery. These complications were strongly associated with one another. No symptom that appeared immediately after birth was identified as a factor that would predict the development of future shoulder contracture. A clavicular fracture was found to be significantly associated with the development of an osseous deformity at a later stag

Shoulder disorders in general practice: Prognostic indicators of outcome

Background. Shoulder pain is common in primary health care. Nevertheless, information on the outcome of shoulder disorders is scarce, especially for patients encountered in general practice. Aim. To study the course of shoulder disorders in general practice and to determine prognostic indicators of outcome. Method. For this prospective follow-up study, 11 Dutch general practitioners recruited 349 patients with new episodes of shoulder pain. The participants filled out a questionnaire at presentation and further ones after 1, 3, 6 and 12 months; these contained questions on the nature, severity and course of the shoulder complaints. The association between potential prognostic indicators and the status of shoulder complaints (absence or presence of symptoms) was evaluated after one and 12 months of follow-up. Results. After one month, 23% of all patients showed complete recovery; this figure increased to 59% after one year. A speedy recovery seemed to be related to preceding overuse or slight trauma and early presentation. A high risk of persistent or recurrent complaints was found for patients with concomitant neck pain and severe pain during the day at presentation. Conclusion. A considerable number of patients (41%) showed persistent symptoms after 12 months. It may be possible to distinguish patients who will show a speedy recovery from those with a high risk of long-standing complaints by determining whether there is a history of slight trauma or overuse, an early presentation or an absence of concomitant neck pain

Neurological recovery in obstetric brachial plexus injuries: an historical cohort study

An historical cohort study was conducted to investigate the rate and extent of neurological recovery in obstetric brachial plexus injury (OBPI) and to identify possible prognostic factors in a cohort of children with OBPI from birth to 7 years. All children (n=56; 31 females, 25 males) with OBPI were evaluated at fixed time intervals by one examiner. They underwent a final neurological examination at a mean age of 3 years 10 months (range 1 to 7 years). Neurological outcome was not as favourable as is often reported: complete neurological recovery occurred in 37 out of 56 children (66%). In half of these there was delayed recovery, in which case complete neurological recovery was assessed from 1.5 to 16 months of age (median age 6.5 months, SD 4.2 months). External rotation and supination were the last to recover and recovered the least. Although biceps function at three months was considered to be the best indicator for operative treatment, external rotation and supination were found to be better in predicting eventual complete recovery. Initial symptoms directly post partum were not found to be prognostic. Functional outcome was mainly reported to be goo
