Stretching is not essential for managing MS spasticity: A randomized controlled trial.

BACKGROUND: Clinical practice, expert opinion, and evidence-based guidelines recommend daily stretching as first-line treatment for multiple sclerosis (MS) spasticity, but this has not been evaluated by fully powered clinical trials. OBJECTIVE: To determine whether MS Spasticity: Take Control (STC), a guideline-based program of spasticity education and stretching exercises has different effects on the impact of spasticity than a control program of different spasticity education and range of motion (ROM) exercises. METHODS: Ambulatory people with self-reported MS spasticity were randomly assigned to STC or ROM, delivered in same duration, facilitator-led, group classes, face-to-face (F2F) initially and later virtually, due to coronavirus disease 2019 (COVID-19). Multiple Sclerosis Spasticity Scale (MSSS) scores were compared between groups at 1 (primary outcome) and 6 months after interventions. RESULTS: A total of 231 people enrolled. There was no significant difference in MSSS scores between STC and ROM at 1 month (mean difference = 0.28, 95% (confidence interval (CI)) = [-9.45 to 10.01], p = 0.955). There were significant group mean improvements in MSSS scores and most other outcomes at 1 and 6 months. CONCLUSION: Education with stretching exercises, the first-line recommended treatment for MS spasticity, and education with ROM exercises may both improve MS spasticity to a similar degree. This study debunks the belief that stretching is essential to managing MS spasticity.

Abdominal bloating in employed adults: prevalence, risk factors, and association with other bowel disorders.

UNLABELLED: BACKGROUND Bloating is common, but its significance as a marker of underlying disease has not been defined. AND AIMS: We report on risk factors for bloating, its relationship to physical activity and quality of life (QOL), and its predictive value for functional bowel disorders. METHODS: This is a cross-sectional population-based study of 1,069 employees of the Veterans Affairs Black Hills Health Care System. The validated Bowel Disease Questionnaire was used to identify subjects with abdominal bloating and other bowel disorders. The association of bloating with QOL was assessed using the SF36 (Short-Form 36) questionnaire. Physical activity was assessed using the modified Baecke questionnaire. RESULTS: The response rate was 72% (723 of 1,069). Bloating was reported by 21% of all subjects (95% confidence interval [CI] 17.7-23.7), 64% with irritable bowel syndrome (IBS), 35% with non-IBS constipation, 23% with non-IBS diarrhea, and 42% with dyspepsia. Functional bloating (i.e., bloating in the absence of other bowel disorders) was reported by 7% of subjects (95% CI 5.2-9.0). Of those with bloating, 28% had IBS, 25% non-IBS constipation, 8% non-IBS diarrhea, and 30% dyspepsia. The positive and negative predictive values of bloating in the diagnosis of functional bowel disorder were 66% and 87%, respectively. The only risk factors were smoking and high-dose aspirin. Bloating was not associated with physical activity. QOL on all subscales of SF36 was lower in subjects with bloating than those without bloating. CONCLUSIONS: Bloating is a common symptom in otherwise healthy adults, and is often associated with but not predictive of functional bowel disorders. Smoking and high-dose aspirin are associated with bloating while physical activity is not.

Is constipation associated with decreased physical activity in normally active subjects?

BACKGROUND: The effectiveness of physical activity in the management of constipation remains controversial. We examined the associations among physical activity, constipation, and quality of life (QoL) in a population of employed adults to determine whether the risk of constipation is related to physical activity. METHODS: A total of 1,069 employees (age range 24-77) of the Veterans Affairs (VA) Black Hills Health Care System were mailed validated questionnaires (response rate 72%), inquiring about bowel habits, QoL (SF 36), and physical activity (modified Baecke questionnaire). Constipation was defined using the Rome I criteria. RESULTS: One hundred and forty (19.4%, 95% CI 16.2-22.4) employees reported constipation. The average total physical activity and all subscales of physical activity were not significantly different in subjects with and without constipation (all p > or = 0.2). Subjects with constipation had lower QoL scores than subjects without constipation, and physical activity was positively correlated with physical functioning and health perception. CONCLUSION: Physical activity appears to be unrelated to the risk of constipation in employed adults, but higher physical activity was associated with improved QoL. Recommendations to increase physical activity may not alter symptoms of constipation but may improve overall well-being.

Chronic fatigue in a population-based study of Gulf War veterans.

Fatigue has been associated with illness in veterans of the Gulf War; however, few studies have confirmed self-reported fatigue by using clinical evaluation, and symptomatic veterans have not been evaluated with established criteria for Chronic Fatigue Syndrome (CFS). The authors describe the frequency and clinical characteristics of CFS in a sample of veterans residing in the northwestern United States. The sample was selected randomly from U.S. Department of Defense databases of troops deployed to southwest Asia during the Gulf War. The selected individuals were invited to participate in a clinical case-control study of unexplained illness. Of 799 survey respondents eligible for clinical evaluation, 178 had fatigue symptoms. Of the 130 veterans who were evaluated clinically, 103 had unexplained fatigue, and 44 veterans met the 1994 U.S. Centers for Disease Control criteria for CFS. In this population, the authors estimated a minimum prevalence of any unexplained fatigue to be 5.1%, and of CFS to be 2.2%. The estimated prevalence was greater among females than among males. Cases were similar to healthy controls, as determined by laboratory tests and physical findings. In comparison to several clinical studies of CFS patients, the authors of this study found a lower proportion of veterans who reported a sudden onset of symptoms (19%) vs. a gradual onset (50%). Although it has previously been suggested that veterans of the Gulf War suffer from higher rates of chronic fatigue than the general population, the study results described herein--on the basis of clinical examination of a population-based sample of veterans-actually indicate that an increased rate may indeed exist. Gulf War veterans with unexplained fatigue should be encouraged to seek treatment so that the impact of these symptoms on overall quality of life can be reduced.

Obesity and upper body fat distribution in Mexican American children from families with a diabetic proband.

Upper and centralized body fat distribution is associated with non-insulin dependent diabetes mellitus (NIDDM). Few studies have focused on anthropometric characteristics of preadults from families in which there is a diabetic (NIDDM) proband. This study explores the prevalence of upper and centralized body fatness in Mexican American children from the Diabetes Alert study (1981-1983) in Starr County, Texas. Anthropometric data on 165 males and 224 females 9-19 years include measures of adiposity such as skinfold thicknesses and the body mass index (BMI), a measure of overweight. They show rates of obesity two to three times that of White children of comparable age and sex from National Health Surveys. In comparison with U.S. White subjects, Mexican American adults are shorter, have more adiposity and arm muscle mass and have sitting heights and body breadths at the mean of these dimensions for the U.S. POPULATION: Children from Diabetes Alert families show only marginal excess of severe obesity (> 95th percentile of BMI) when compared to the general population of children surveyed in Starr County schools. Girls from these families, but not boys, have excess fatness in the BMI compared to Mexican American children from the Hispanic Health and Nutrition Examination Survey (HHANES); suprailiac skinfold thicknesses are also greater in children of the Diabetes Alert study than in HHANES children. From 1972 through 1982, Mexican American children in South Texas showed an increase in average stature, weight, and the BMI. These data together suggest that excessive obesity exists and may be increasing in children in populations at risk for NIDDM. The prevention of NIDDM in the Mexican American population may be more effective if educational and promotional interventions include the school aged population. © 1993 Wiley-Liss, Inc.
