Impact of physical activity during pregnancy and postpartum on chronic disease risk.

Research over the past 20 years has focused on the safety of physical activity during pregnancy. Guidelines for health care providers and pregnant/postpartum women have been developed from the results of these studies. The overwhelming results of most studies have shown few negative effects on the pregnancy of a healthy gravida, but rather, be beneficial to the maternal-fetal unit. Recently, researchers have begun to consider the role of maternal physical activity in a more traditional chronic disease prevention model, for both mother and offspring. To address the key issues related to the role of physical activity during pregnancy and postpartum on chronic disease risk, the American College of Sports Medicine convened a Scientific Roundtable at Michigan State University in East Lansing, MI. Topics included preeclampsia, gestational diabetes, breastfeeding and weight loss, musculoskeletal disorders, mental health, and offspring health and development.

Clinical signs and physical function in neck and upper extremities among elderly female computer users: the NEW study.

The aim of the study was to present the prevalence of clinical signs and symptoms among female computer users above 45 years, both in a group with self-reported neck/shoulder trouble (NS cases) and in a group without such trouble (NS controls). The hypothesis was that computer users with self-reported neck/shoulder trouble have more clinical findings than those not reporting trouble, and that a corresponding pattern holds true for physical function. In total 42 and 61 questionnaire-defined NS cases and NS controls participated and went through a clinical examination of the neck and upper extremities and five physical function tests: maximal voluntary contraction (MVC) of shoulder elevation, abduction, and handgrip, as well as endurance at 30% MVC shoulder elevation and a physical performance test. Based on clinical signs and symptoms, trapezius myalgia (38%), tension neck syndrome (17%) and cervicalgia (17%) were the most frequent diagnoses among NS cases, and were significantly more frequent among NS cases than NS controls. A total of 60% of the subjects with reported trouble had one or several of the diagnoses located in the neck/shoulder. Physical function of the shoulder was lower in subjects with self-reported trouble as well as in the subgroup of NS cases with clinical diagnoses. In conclusion, the present clinical diagnoses and physical function tests differed between NS cases and NS controls, and are therefore recommended to be included as quantitative objective measures in assessing musculoskeletal health. Physical function tests should be further developed in order to be able to detect pre-stages of work-related disorders for preventive strategies.

Use of primary health services in sparsely populated country districts by patients with musculoskeletal symptoms: consultations with a physician.

STUDY OBJECTIVE: To examine the extent to which people consult health centre doctors about various musculoskeletal symptoms and to identify those groups of patients who are responsible for the main workload in primary health care caused by musculoskeletal complaints. DESIGN: A cross sectional investigation based on case records of people who visited health centre physicians. SETTING: The population of six Finnish health centre districts (93,000 inhabitants, 64 physicians' posts in primary care centres). SUBJECTS: 6526 patients (7634 visits) who consulted a physician at any of six health centres during a two week period, of which 1380 consulted for musculoskeletal symptoms. MEASUREMENTS AND MAIN RESULTS: The reasons for the visits were abstracted from the case records and were analysed by cross tabulation. The rate of people visiting for musculoskeletal symptoms during a two week period was on average 15 per 1000 inhabitants. It was highest in men aged 45-54 years (25/1000) and in women aged 55-64 years (26/1000); the rate fell to the average in men over 54 and women over 64 years. Patients with musculoskeletal symptoms accounted for 21% of all patients and 27% of those over 15 years of age. Low back pain was the most common reason for consultation in men aged 25-54 years, while for women aged 35-74 years, the most common reason was neck and shoulder pain. CONCLUSIONS: Over one quarter of adults visiting a health centre doctor do so because of musculoskeletal disorders. This fact must be considered when developing health care services and organising basic education and further in-service training for doctors.

Secondary conditions of the musculoskeletal system in adolescents and adults with cerebral palsy.

Cerebral palsy (CP) is a disability that affects individuals throughout their lifespan. Adolescents and adults with CP are at risk for many secondary conditions that cause a loss of function and deterioration of quality of life. This article presents a review of the literature of musculoskeletal conditions of people with CP that can develop or worsen across the lifespan as a consequence of the primary neuromotor impairments. Health care behaviors of adolescents and adults with CP are discussed and their impact on secondary conditions is examined. Suggestions for how pediatric occupational therapists and physical therapists can assist children and adolescents to take responsibility for their own health and wellbeing are presented. Lastly, occupational therapists and physical therapists are encouraged to take responsibility for treating musculoskeletal impairments and disabilities in adults with CP.

Marfan's syndrome with aortic valve endocarditis.

Marfans syndrome is an Autosomal dominant disorder of the connective tissues resulting in abnormalities of the musculoskeletal system, cardiovascular system and eyes. It has a prevalence of 1 in 100,000 population1 and occurs in all ethnic groups. It may be familial or due to new mutation (30%), in the fibrillin gene on arm of chromosome 15. It is estimated that one person in every 3000-5000 has Marfans syndrome may have cardiovascular abnormalities and may be complicated by infective endocartditis. About 90% of Marfan patients will develop cardiac complications2. The patient under discussion has musculoskeletal (Tall stature, reduced upper-lower segment ratio, arm-span to height ratio > 1.05, high arched palate) and Cardiovascular features (Severe aortic regurgitation complicated with infective endocarditis).

American Academy of Orthopaedic Surgeons lower limb outcomes assessment instruments. Reliability, validity, and sensitivity to change.

BACKGROUND: The American Academy of Orthopaedic Surgeons (AAOS) has developed an array of outcomes assessment instruments designed for the efficient collection of outcomes data from patients of all ages with musculoskeletal conditions in all body regions. The Lower Limb Instruments were developed through a process of literature review, consensus-building, and field-testing. METHODS: The instruments were distributed to a total of 290 subjects in twenty orthopaedic practices throughout the United States and Canada. Of the 290 patients, seventy each had a diagnosis in the categories of foot and ankle, sports/knee, and hip and knee and forty each had a diagnosis in the categories of trauma and rehabilitation. Retests to be taken twenty-four hours after the first test were distributed to subsamples of patients for each instrument. Seventy-one one-year follow-up questionnaires (twenty-five Sports/Knee, twenty-five Foot and Ankle, sixteen Hip and Knee, and five Lower Limb Core instruments) were returned. RESULTS: The Lower Limb Core Scale and the Hip and Knee Core Scale, each consisting of seven items addressing pain, stiffness and swelling, and function, performed at an acceptable level. Additional Sports/Knee and Foot and Ankle Modules proved to have internal and retest reliability of 0.80 or better, comparable with the values for well-established measures such as the Short Form-36 (SF-36). All of the new scales were moderately to strongly correlated with other measures of pain and function, such as physician ratings, the SF-36, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Seventy-one patients provided follow-up information for the analysis of sensitivity to change. The Lower Limb Core was found to contribute independently to the prediction of the transition score based on the patient and physician assessments of change. CONCLUSIONS: The AAOS Lower Limb Instruments for outcomes assessment are highly reliable and are correlated with other measures for similar constructs. They are also sensitive to change in patient status. The Lower Limb Core Scale may be used with attribution of pain either to the lower limb or to a specific joint or side without sacrificing reliability. Combined with the SF-36, the AAOS outcomes assessment instruments comprehensively and efficiently measure outcomes in orthopaedic patients with lower-limb conditions.

Therapeutic ultrasound for osteoarthritis of the knee.

BACKGROUND: Therapeutic ultrasound is one of several physical therapy modalities suggested for the management of pain and loss of function due to OA. OBJECTIVES: To assess the effectiveness of therapeutic ultrasound therapy for treating OA. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Group trials register, and MEDLINE, up to the end of December 2000, using the sensitive search strategy developed by the Cochrane Collaboration. The search was complemented with bibliography searching of the reference list of the trials retrieved from the electronic search. Key experts in the area were contacted for further published and unpublished articles. SELECTION CRITERIA: All randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing therapeutic ultrasound against placebo or another active intervention in patients with OA were selected. DATA COLLECTION AND ANALYSIS: Two reviewers determined the studies to be included based on inclusion and exclusion criteria (LB, VW). Data were independently abstracted by two reviewers (VW, LB), and checked by a third reviewer (BS) using a pre-developed adapted form for the OA sub-group of the Cochrane Musculoskeletal Group. The same two reviewers, using a validated scale, assessed the methodological quality of the RCTs and CCTs independently. OA outcome measures were extracted from the publications. The pooled analysis was performed using weighted mean differences (WMDs) for joint counts, pain, global and functional assessments. A chi-square test was used to assess heterogeneity among trials. Fixed effects models were used throughout and random effects for outcomes showing heterogeneity. MAIN RESULTS: Three trials, including 294 patients with knee OA were included. Only one trial (n=74) compared therapeutic ultrasound to placebo. This trial showed no difference in range of motion, pain or gait velocity after 4 weeks of therapeutic ultrasound. Two trials compared therapeutic ultrasound to an active therapy (n=220). These trials showed no statistical difference between galvanic current or short wave diathermy for the outcomes of pain and patient-assessed improvement. REVIEWER'S CONCLUSIONS: Ultrasound therapy appears to have no benefit over placebo or short wave diathermy for patients with knee OA. These conclusions are limited by the poor reporting of the characteristics of the device, of the population, of the OA,and therapeutic application of the ultrasound and low methodological quality of the trials included. No conclusions can be drawn about the use of ultrasound in smaller joints such as the wrists or hands.

Validation of a questionnaire for assessing physical work load.

OBJECTIVES: Reliable, valid, and compatible methods are required for exploring the complex interactive effects of psychosocial and physical stressors on complaints and disorders. An instrument for assessing physical work load that integrates information from a biomechanical model of lumbar load is presented and validated. METHODS: Four hundred and fifty-five people working in nursing homes for elderly people in Germany filled out the developed questionnaire 3 times within 1 year. Test-retest reliability was calculated, and validity was checked several times. Relationships with other, theoretically related and unrelated variables were examined. RESULTS: The test-retest reliability of the questionnaire measures was about 0.65. The convergent and discriminant validity was satisfactory, and the questionnaire was able to separate professional subgroups with different physical work loads. The Spearman rank-order correlations between physical load and musculoskeletal complaints were about 0.30. CONCLUSIONS: The method developed in this study is a reliable and valid instrument for assessing physical work load. The integration of statistical methods from psychological testing and theory in the development of methods exploring the effects of physical work load is advocated.

Ergonomics method for prevention of the musculoskeletal discomforts among female industrial workers: physical characteristics and work factors.

In industrial work, working postures play an important role, separately and combined with other strain factors. The combined effects may be worse than those of single factors. The purpose of this investigation was to compare the body size, work postures and musculoskeletal discomforts between a group of female workers in a pharmaceutical plant and another group in a textile plant. Two hundred workers have participated in the following studies; (i) measuring anthropometric data in the standing and sitting positions, (ii) using the Ovako Working Posture Analysis System (OWAS), and (iii) using the detail Standardized Nordic Questionnaire for analyzing the musculoskeletal troubles in different parts of the body. The investigation has identified five main factors associated with the musculoskeletal discomforts: (i) lack of worker selection and lack of appropriate training to prevent occupational hazards or work-related diseases, (ii) poor ergonomic design of the work place and task including work organization, (iii) poor working postures, (iv) lack of task variation, and (v) insufficient rest breaks. These could be improved by introducing ergonomic interventions for both adjusting the individual work places and the task performed. It is necessary to consider preventive measures for musculoskeletal disorders, especially for female workers in industrially developing countries. Ergonomic aspects of the preventive measures should include: (a) consideration of appropriate worker selection for various works with sufficient training and instruction, (b) ergonomic redesign of work places, and (c) ergonomic considerations in work organization.

Competence levels in musculoskeletal medicine: comparison of osteopathic and allopathic medical graduates.

BACKGROUND: Consistent with osteopathic principles and practice, the nation's colleges of osteopathic medicine (COMs) have emphasized the significance of the musculoskeletal system to the practice of medicine. The authors hypothesized that graduating COM students would, therefore, demonstrate superior knowledge and competence in musculoskeletal medicine when compared with graduates of allopathic medical schools. METHODS: The authors asked graduating COM students to complete a standardized and previously validated 25-question basic competency examination on musculoskeletal medicine in short-answer format. Originally developed and validated in the late 1990s, the examination was distributed to allopathic medical residents at the beginning of their residencies. The authors compare their results with those reported by Freedman and Bernstein for allopathic residents. RESULTS: When the minimum passing level as determined by orthopedic program directors was applied to the results of these examinations, 70.4% of graduating COM students (n=54) and 82% of allopathic graduates (n=85) failed to demonstrate basic competency in musculoskeletal medicine. Similarly, the majority of both groups failed to attain the minimum passing level established by the directors of internal medicine programs (graduating COM students, 67%; allopathic graduates, 78%). CONCLUSION: In an examination of competence levels for musculoskeletal medicine, students about to graduate from a COM fared only marginally better than did their allopathic counterparts. To ensure that all graduating COM students have attained a level of basic competence in musculoskeletal medicine, the authors recommend further study as a prelude to evaluation of the didactic and clinical curriculum at all 22 COMs and their branch campuses.

Workplace changes associated with a reduction in musculoskeletal symptoms in office workers.

The purpose of this study was to identify factors associated with reductions observed in musculoskeletal symptoms when office workers were moved to a new building. A questionnaire including items regarding symptoms and aspects of the work environment was administered to 577 office workers before and after they were moved from nine buildings to a single new facility in 1992. Employees working in two reference buildings, where they remained throughout the study period, were also surveyed. Two musculoskeletal outcomes, hand/arm and neck/shoulder/back, were selected for study. In matched multivariate analyses, the reduction in hand/arm symptoms from 1992 to 1993 was associated with improved satisfaction with the physical workstation (odds ratio [OR] = 2.0); the reduction in neck/shoulder/back symptoms was associated with improved chair comfort (OR = 1.8), fewer housekeeping responsibilities (OR = 3.6), female gender (OR = 1.8), and low pay range (OR = 1.7). Longitudinal results suggested that changes in workstations resulted in decreased symptoms. Results of this investigation might be used to develop workplace changes that result in reductions of musculoskeletal disorders.

Back and upper extremity disorders among enlisted U.S. Marines: burden and individual risk factors.

Although musculoskeletal disorders of the low back and upper extremities can affect military readiness, little is known about their extent and risk factors in the U.S. Marine Corps. Using the Defense Medical Epidemiology and Defense Medical Surveillance System databases, back and upper extremity diagnostic categories were among the top four sources of outpatient visits and duty limitation among enlisted Marines. Back disorders were also found to be the fifth most common cause for lost time. Subsequently, high-risk occupations were identified, age-related trends for clinic visit rates were determined, and rate ratios were computed for the top 15 low back and upper extremity diagnoses among enlisted Marines from 1997 through 1998. Occupational categories with the highest rates of musculoskeletal-related outpatient visits included image interpretation, auditing and accounting, disturbsing, surveillance/target acquisition, and aircraft launch equipment. Significantly increasing linear trends in rates across age groups were found for most diagnoses. For 1998, age-specific rate ratios indicated significantly higher rates for most low back and upper extremity disorders for females; lower rank (i.e., E1-E4) was also a risk, but for fewer diagnoses. The findings emphasize the need to identify modifiable (e.g., work-related, individual) risk factors and to develop focused primary and secondary prevention programs for musculoskeletal disorders in the Marine Corps. Subsequently, these efforts can assist in reducing associated effects, maximizing resource utilization, and enhancing operational readiness.

Impairment, disability, and handicap.

It seems clear that the orthopedic surgeon cannot separate impairment from disability. The measurement of impairment is clouded by the inability to measure dynamic function. A range of motion demonstrated by a patient in the doctor's office does not fully describe the functional potential of either the extremity or the spine. Moreover, the rules by which disability is defined are interpreted with a natural sympathy of the physician's care for the patient. The physician may have less sympathy if the individual being reviewed is a client of an insurance company or of an attorney, compared to being a "private" patient. In the future, the orthopedic surgeon would focus on the musculoskeletal handicap rather than disability, or function rather than impairment. Function must be measured in a dynamic manner. The guidelines for definition of function or dysfunction should be similar to those used in sports medicine regarding the decision as to when the athlete can resume sports. What was the capacity before injury? How close to the normal capacity has medical care restored function? This includes measurements of passage of time and consideration of the desire to return to previous activity. The goal is the development of methods that will accurately measure dynamic musculoskeletal function. Visceral organ systems have biochemical standards of measurement; comparable standards must be devised for the musculoskeletal system.

Development of an upper extremity outcome measure: the DASH (disabilities of the arm, shoulder and hand) [corrected]. The Upper Extremity Collaborative Group (UECG)

This paper describes the development of an evaluative outcome measure for patients with upper extremity musculoskeletal conditions. The goal is to produce a brief, self-administered measure of symptoms and functional status, with a focus on physical function, to be used by clinicians in daily practice and as a research tool. This is a joint initiative of the American Academy of Orthopedic Surgeons (AAOS), the Council of Musculoskeletal Specialty Societies (COMSS), and the Institute for Work and Health (Toronto, Ontario). Our approach is consistent with previously described strategies for scale development. In Stage 1, Item Generation, a group of methodologists and clinical experts reviewed 13 outcome measurement scales currently in use and generated a list of 821 items. In Stage 2a, Initial Item Reduction, these 821 items were reduced to 78 items using various strategies including removal of items which were generic, repetitive, not reflective of disability, or not relevant to the upper extremity or to one of the targeted concepts of symptoms and functional status. Items not highly endorsed in a survey of content experts were also eliminated. Stage 2b, Further Item Reduction, will be based on results of field testing in which patients complete the 78-item questionnaire. This field testing, which is currently underway in 20 centers in the United States, Canada, and Australia, will generate the final format and content of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Future work includes plans for validity and reliability testing.

Detection of c-fos expression in benign and malignant musculoskeletal lesions.

The proto-oncogene c-fos has been implicated in the development of both benign and malignant lesions of bone. Although c-fos expression in such lesions has been well studied in transgenic mouse models, less is known about its role in human musculoskeletal pathology. To clarify this relationship, we used in situ hybridization to localize c-fos m-RNA transcripts in 26 fibrous lesions (eight cases of extra-abdominal fibromatosis and six cases each of fibrous dysplasia, fibrosarcoma, and malignant fibrous histiocytoma of bone) as well as six chondrosarcomas and eight conventional high grade osteosarcomas. We found detectable levels of c-fos expression in tissues from each type of lesion tested. Moreover, all fibrous lesions consistently demonstrated high levels of expression in a majority of cells in each lesion. Chondrosarcomas and osteosarcomas exhibited more heterogeneity in c-fos expression than fibrous tissues. Three of six chondrosarcomas showed moderate expression of c-fos while only one of six was considered high. Similarly, only three of eight osteosarcomas had high expression of c-fos. These findings indicate that the expression of c-fos may be important in the development of a broad range of fibrous lesions as well as in bone and cartilaginous tumors. Additionally, this is the first report, to our knowledge, of detectable c-fos m-RNA in human chondrosarcoma.
