Pulmonary rehabilitation for chronic obstructive pulmonary disease.

BACKGROUND: The widespread application pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function attributable to the programs. This review updates that reported by Lacasse et al Lancet 1996; 748:1115-1119. OBJECTIVES: To determine the impact of rehabilitation on health-related quality of life (QoL) and exercise capacity in patients with COPD. SEARCH STRATEGY: The 14 randomized controlled trials (RCTs) included in the original meta-analysis were included. Additional RCTs were identified from the Cochrane Airways Group's registry of COPD RCTs using the strategy: [exp, lung diseases, obstructive] and [exp, rehabilitation or exp, exercise therapy] and [research design or longitudinal studies or evaluation study or randomized controlled trial]. Abstracts presented at American Thoracic Society 1980-2000, American College of Chest Physicians 1980-2000 and European Respiratory Society 1987-2000 were also searched. SELECTION CRITERIA: RCTs of rehabilitation in patients with COPD in which quality of life (QoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. Rehabilitation was defined as exercise training for at least 4 weeks with or without education and/or psychological support. Control groups received conventional community care without rehabilitation. DATA COLLECTION AND ANALYSIS: Weighted mean differences (WMD) were calculated using a random-effects model. Missing data from the primary study reports were requested from the authors. MAIN RESULTS: 23 RCTs met the inclusion criteria. Statistically significant improvements were found for all the outcomes. In three important domains of QoL (Chronic Respiratory Questionnaire scores for Dyspnea, Fatigue and Mastery), the effect was larger than the minimal clinically important difference of 0.5 units using this instrument. For example Dyspnoea score: WMD 0.98 units, 95% Confidence Interval (95% CI) 0.74 - 1.22 units; n=9 trials. For FEC and MEC, the effect was small and a little below the threshold of clinical significance for the 6- minute walking distance: WMD 49 m, 95% CI: 26 - 72 m; n=10 trials. REVIEWER'S CONCLUSIONS: Rehabilitation relieves dyspnea and fatigue and enhances patients' sense of control over their condition. These improvements are moderately large and clinically significant. The average improvement in exercise capacity was modest. Rehabilitation forms an important component of the management of COPD.

Effects of exercise and estrogen therapy on lipid profiles of postmenopausal women.

PURPOSE: We compared the effects of aerobic exercise training on lipid and lipoprotein levels in 18 postmenopausal women who were (N = 8) or were not (N = 10) receiving estrogen replacement therapy (ERT). METHODS: Each group was tested for lipids, diet recall and VO2max before and after a 12 wk exercise program, consisting of 30-50 min of an aerobic activity at 75-85% of VO2max, 3-4 sessions per week. RESULTS: Both groups increased VO2max by 8% and neither group changed their diet. The ERT group had higher levels of triglycerides and lower levels of low density lipoprotein (LDL-C) (P < 0.01) before training. There were no mean group changes in any of the lipid variables with training. However, individual changes in LDL-C and Total Cholesterol (TC) were strongly related to baseline weight in the nonestrogen group (r = 109.91, r = -0.82) but not in ERT (r = -0.30, r = -0.51). Subsequently, all subjects were redivided into two groups based on BMI (< or = 27 or > or = 27) regardless of ERT status. TC decreased significantly (P < 0.05) in the < or = 27 BMI group. CONCLUSIONS: Exercise training had little effect on the lipid profiles of the ERT and the nonestrogen groups, but body weight seems to be a modulating factor. Heavier subjects did not respond as favorably to 12 wk of exercise training as postmenopausal women with less body mass, regardless of the presence of exogenous estrogen.

Treatment categories for low back pain: a methodological approach.

Studies that evaluate effectiveness of physical therapy can be problematic because frequently several treatment techniques are used during an episode of care. Methods that categorize treatment techniques into discrete categories may be useful in studying treatment outcomes. The purpose of this study was to describe a method to create treatment categories used for patients with low back pain. We surveyed physical therapists in Virginia to identify frequently used treatments for patients with low back pain. One hundred fifty-five surveys were completed. Twenty-eight treatments, used frequently or very frequently by 50% or more of the respondents, were retained for analysis. Factor analysis was used to identify treatment categories. Seven categories were identified: McKenzie approach, manual therapy, exercise with equipment, active and stretching exercise, physical agents, aerobic exercise and walking, and ergonomic activities. Indices for the categories were created. Confirmatory factor analyses should be performed on a different sample to validate these findings.

[Fibromatosis colli--a benign tumor of the neck in diagnosis and therapy].

Fibromatosis colli is a benign tumor of infancy, and although prognosis is usually good, it is the most frequent cause of congenital torticollis. The clinical picture, sonography, or, if required, CT scans, permit a clear diagnosis. Invasive diagnostic and therapeutic measures should be avoided and restricted to those cases, where a malignancy is suspected with good reason or where local complications due to bulk shifts and compression are anticipated. Even after the usually spontaneous remission of the tumor torticollis may develop later on so that accompanying exercise therapy should be provided from infancy to school age.

Systematic review of randomized controlled trials of nonpharmacological interventions for fibromyalgia.

OBJECTIVE: Little is known of the effectiveness of nonpharmacological interventions for fibromyalgia syndrome (FMS). The authors therefore carried out a systematic review from 1980 to May 2000 of randomized controlled trials (RCTs) of nonpharmacological interventions for FMS. METHOD: A search of computerized databases was supplemented by hand searching of bibliographies of key publications. The methodological quality of studies included in the review was evaluated independently by two researchers according to a set of formal criteria. Discrepancies in scoring were resolved through discussion. RESULTS: The review yielded 25 RCTs, and the main categories of interventions tested in the studies were exercise therapy, educational intervention, relaxation therapy, cognitive-behavioral therapy, acupuncture, and forms of hydrotherapy. Methodological quality of studies was fairly low (mean score = 49.5/100). Most studies had small samples (median for individual treatment groups after randomization = 20), and the mean power of the studies to detect a medium effect ( > or = 0.5) was 0.36. Sixteen studies had blinded outcome assessment, but patients were blinded in only 6 studies. The median longest follow-up was 16 weeks. Statistically significant between-group differences on at least one outcome variable were reported in 17 of the 24 studies. CONCLUSIONS: The varying combinations of interventions studied in the RCTs and the wide range of outcome measures used make it hard to form conclusions across studies. Strong evidence did not emerge in respect to any single intervention, though preliminary support of moderate strength existed for aerobic exercise. There is a need for larger, more methodologically rigorous RCTs in this area.

Effects of cilazapril on exercise tolerance in the chronic phase of acute myocardial infarction.

The present study was conducted to investigate the effects of cilazapril on exercise tolerance and the hormone kinetics of catecholamines, the reninangiotensin-aldosterone system and alpha-atrial natriuretic peptide (ANP) in patients in the chronic phase of acute myocardial infarction (AMI). The subjects consisted of 19 cases of AMI. Cardiopulmonary exercise testing was performed 1 month after the onset of AMI, and patients were randomly assigned to either a group treated with 1 mg/day of cilazapril (9 cases) and or an untreated group (10 cases). After the completion of 2 months of exercise training at the anaerobic threshold (AT), blood samples were taken during a cardiopulmonary exercise test and various hormones were measured. In comparing the parameters of exercise tolerance before and after the completion of exercise training there were no significant differences between the 2 groups with respect to oxygen uptake, oxygen pulse, or exercise time at AT or at peak exercise. With regard to temporal changes in exercise tolerance, oxygen uptake, oxygen pulse and exercise time all tended to increase in both groups. With regard to hormone kinetics, the alpha-ANP concentration at peak exercise was significantly lower, and the noradrenaline secretions also tended to be lower, in the cilazapril-treated group, even though the peak exercise time was similar in both groups. These results may be support the hypothesis that cilazapril mitigates the left ventricular load during exercise therapy in patients in the chronic phase of AMI.

Physical therapy outcomes for persons with bilateral vestibular loss.

OBJECTIVE: The purpose of the study was to assess the efficacy of physical therapy for patients with bilateral vestibular loss. STUDY DESIGN: Retrospective case series. METHODS: Twenty-four patients with a diagnosis of bilateral vestibular loss were identified by a retrospective chart review. Thirteen of the 24 patients met the inclusion criteria of having a moderate or greater loss of vestibular function bilaterally as rated by an otoneurologist based on the patient's vestibular function tests. These patients were treated with a custom-designed physical therapy program for a mean of 4.6 visits over an average period of 3.8 months. Patients completed the Dizziness Handicap Inventory and the Activities-specific Balance Confidence Scale at initial evaluation and discharge. Patients were asked to perform the balance and gait tasks of the Dynamic Gait Index, Sensory Organization Test of computerized dynamic posturography, and the Timed "Up and Go" test at their first and last physical therapy sessions. The number of falls in the previous 4 weeks and the use of an assistive device at initial evaluation and discharge were reported. Composite score, an overall score of clinical outcome, was calculated to determine clinically significant changes in physical performance and subjective information. RESULTS: On a population basis, statistically significant improvement was observed after physical therapy for each of the outcome measures including the composite score (P < .05). Clinically significant changes were demonstrated by 33% to 55% of the patients on the various outcome measures. No change was noted in the patients' risk of falling, their number of falls, and the use of assistive devices. CONCLUSION: Many patients with bilateral vestibular loss benefit from an individualized vestibular physical therapy exercise program based on improved physical function and reduced self-perceived levels of handicap.

Nonpharmacologic therapy of osteoarthritis.

Studies of the nonpharmacologic treatment of osteoarthritis (OA) have fallen behind that of pharmacologic therapy for a variety of reasons. The design of studies that involve a therapist-delivered physical intervention presents several problems with respect to patient and observer blinding, the beneficial effect of therapist contact alone, and separation of the effects of individual components of the "package" of delivered care. Important developments in the design and reporting of OA trials are discussed. Recent studies have demonstrated the modest but definite benefits of exercise therapy for OA of the knee, delivered either in hospital, primary care, or community settings. The reduction in pain and disability through an arthritis self-management group education program may extend to at least 1 year. Recent data that low intake of micronutrients (vitamins C, E, and D, and beta-carotene) may adversely influence the progression of knee OA and the incidence of hip OA suggest potential avenues for primary and secondary prevention of large joint OA.

The effect of age on vestibular rehabilitation outcomes.

OBJECTIVE: The purpose of the retrospective chart review was to compare vestibular rehabilitation outcomes in young versus older adults. STUDY DESIGN: Retrospective matched design. METHODS: Twenty-three persons with vestibular disorders aged 20 to 40 years were matched by gender, vestibular diagnosis, and vestibular function test results to 23 older adults aged 60 to 80 years. The patients were treated with a custom-designed physical therapy exercise program. Patients completed the Dizziness Handicap Inventory, the Activities-Specific Balance Confidence (ABC) scale, and the Dynamic Gait Index; number of falls; and rated the severity of their dizziness. The two-sample test, the Mann-Whitney test, and McNemar's test for correlated proportions were used to determine whether there was a difference in scores between the two age groups at the beginning and end of physical therapy. RESULTS: During the initial evaluation, older adults reported having statistically greater space and motion discomfort and more severe symptoms on a scale of 0 to 100. Younger adults had more impaired DGI scores and a higher proportion of caloric testing abnormalities. After rehabilitation, overall improvement was seen in both the younger and older populations. There were no statistical differences between the two groups on the DHI, the DGI, reported symptoms at discharge, or number of falls. When only the complete matched-pair data were analyzed, there were no statistically significant differences between the age groups in the proportion of patients demonstrating clinical improvement. CONCLUSION: Age does not significantly influence the beneficial effects of vestibular rehabilitation for persons with vestibular disorders.

Individually tailored treatment targeting activity, motor behavior, and cognition reduces pain-related disability: a randomized controlled trial in patients with musculoskeletal pain.

UNLABELLED: This study compares the outcomes of an individually tailored behavioral medicine intervention (experimental) with physical exercise therapy (control). The experimental intervention was systematically individualized according to each participant's behavioral treatment goals and functional behavioral analyses. One hundred twenty-two patients seeking care at 3 primary health care clinics because of musculoskeletal pain were randomized. Ninety-seven completed the trial. Data were collected at baseline, immediately after treatment, and at a 3-month follow-up. Analyses of data from completers, as well as intention-to-treat analyses, showed that the experimental group experienced lower levels of disability (P = .01), lower maximum pain intensity (P = .02), higher levels of pain control (P = .001), and lower fear of movement (P = .022) as a result of treatment condition. Self-efficacy (P = .0001) and physical performance (P = .0001) increased over time for both groups. Participants in the experimental group generally reported more positive effects after treatment. Treatment fidelity was maintained during the course of the study. Activity can be resumed and pain might be managed by the patients themselves if treatment incorporates the biopsychosocial explanatory model of pain and strategies are tailored according to individual's priorities of everyday life activities and empirically derived determinants of pain-related disability. PERSPECTIVE: This study shows that the biomedical and the psychosocial perspectives of the experiences and consequences of pain complement rather than contradict each other. Primary health care patients with persistent musculoskeletal pain benefit more from a systematic tailoring of treatments according to biopsychosocial factors than from a physically based exercise intervention.

Randomized controlled study of in-hospital exercise training programs in children with cystic fibrosis.

The aim of this study was to compare aerobic and resistance training in children with cystic fibrosis (CF) admitted to hospital with an intercurrent pulmonary infection with a control group. The subjects were randomized into three groups on the first day of admission. The fat-free mass (FFM) was calculated, using the skin fold thickness from four sites (biceps, triceps, subscapular, and iliac crest). Pulmonary function tests were performed within 36 hr of admission and repeated on discharge from the hospital, and again at 1 month after discharge. All subjects performed an incremental treadmill exercise test, using a modified Bruce protocol. Lower limb strength was measured using a Cybex dynamometer. An assessment of quality of life was made using the Quality of Well Being Scale, as previously reported. Activity levels were measured using a 7-day activity diary, and subjects also wore an accelerometer on their hips. There were no significant differences between the three groups in terms of disease severity, and length of stay in hospital. Subjects in all three groups received intravenous antibiotics and nutritional supplementation as determined by the physician. Children randomized to the aerobic training group participated in aerobic activities for five sessions, each of 30-min duration, a week. The children randomized to the resistance training group exercised both upper and lower limbs against a graded resistance machine. Subjects in the control group received standard chest physiotherapy. Our study demonstrated that children who received aerobic training had significantly better peak aerobic capacity, activity levels, and quality of life than children who received the resistance training program. Children who received resistance training had better weight gain (total mass, as well as fat-free mass), lung function, and leg strength than children who received aerobic training. A combination of aerobic and resistance training may be the best training program, and future studies to assess optimal training programs for CF patients are indicated.

Conservative treatment of sciatica: a systematic review.

Most patients with sciatica (often caused by disc herniations) are managed conservatively at first. The natural course seems to be favorable. The additional value of many conservative therapies remains controversial. Because a systematic review of the conservative treatment of sciatica is lacking, such a review was carried out. After a standardized literature search and selection procedure, methodology and outcome of randomized controlled trials (RCTs) were assessed by three observers. If possible, trial results were statistically pooled (= metaanalysis). The 19 RCTs that were selected showed greatly varying methodologic quality. Pooled odds ratios were calculated for several treatment types. Neither traction, exercise therapy, nor drug therapy was unequivocally effective. Epidural steroids may be beneficial for subgroups of nerve root compression. The literature suggests possible effectiveness of epidural steroids for sciatica. The authors recommend trials to investigate this treatment option further, especially with regard to patient subgroups (e.g., acute sciatica). The effects of clinical heterogeneity and methodology on review results are illustrated.

Combined inpatient rehabilitation and spa therapy for breast cancer patients: effects on quality of life and CA 15-3.

The present study investigated the changes of quality of life, mood, and the tumor marker CA 15-3 associated with a 3-week inpatient breast cancer rehabilitation program incorporating spa therapy. One hundred forty-nine women, 32 to 82 years, participated in the study 3 to 72 months after breast cancer surgery. Quality of life (QoL, EORTC QLQ-C30), anxiety, and depression (HADS) were measured 2 weeks before, at the end, and 6 months after rehabilitation; CA 15-3 at the beginning, end, and at 6 months follow-up. Patients received an individualized rehabilitation program incorporating manual lymph drainage, exercise therapy, massages, psychological counseling, relaxation training, carbon dioxide baths, and mud packs. Quality of life and mood improved significantly, the greatest short-term improvements found for mood-related aspects of quality of life, the most lasting improvements found for physical complaints (eg, fatigue). Also, the tumor marker CA 15-3 declined significantly to follow-up. Patient characteristics, as well as the time since surgery, moderated rehabilitation outcome to a limited extent. Older patients, nonobese patients, patients with a greater lymphedema, and patients with an active coping style showed slightly greater improvements. Hot mud packs inducing hyperthermia did not affect CA 15-3. In conclusion, the combination of inpatient rehabilitation with spa therapy provides a promising approach for breast cancer rehabilitation.

The effectiveness of outpatient pulmonary rehabilitation in chronic lung disease: a randomized controlled trial.

BACKGROUND: Patients with chronic pulmonary disease have been shown to benefit from pulmonary rehabilitation programs. Published work has often been from specialized teaching centers and has involved inpatient stay. We assessed an entirely outpatient-based program of pulmonary rehabilitation in patients with chronic lung disease, using the St. George's Respiratory Questionnaire (SGRQ) (which measures health-related quality of life) as the primary outcome measure. METHODS: We undertook a randomized, prospective, parallel-group controlled study of an outpatient rehabilitation program in 65 patients with COPD (44 men and 21 women; mean age, 69.5 years [SD, 9.2 years]; FEV(1), 41% predicted [SD, 18.5%]). The active group (n = 36) took part in a 6-week program of education (2 h weekly) and exercise (1 h weekly). The control group (n = 29) were reviewed routinely as medical outpatients. The SGRQ was administered under supervision by a blinded observer at study entry, 12 weeks, and 24 weeks. RESULTS: The SGRQ in the active group was 59.9 (SE, 2.0) at study entry (n = 36), 47.4 (SE, 2.3) at 12 weeks (n = 32), and 50.6 (SE, 2.5) at 24 weeks (n = 24). The SGRQ in the control group was 59.3 (SE, 2.5) at study entry and did not change significantly over 24 weeks. There was a difference of 10.4 points (confidence interval [CI], 3.6 to 17.3) between the two groups at 12 weeks (p < 0.001) and of 8.1 points (CI, 1.4 to 14.9) at 24 weeks (p = 0.02) in favor of the active group. CONCLUSIONS: A 6-week outpatient-based program significantly improved quality of life in patients with moderate-to-severe COPD. Benefit was still evident after 24 weeks.

Pulmonary hypertension and chronic obstructive pulmonary disease: a case for treatment.

Current pharmacotherapy for chronic obstructive pulmonary disease (COPD) relieves symptoms and reduces exacerbation through improving airflow limitation. Such drugs do not effectively improve exercise tolerance due in part to pulmonary hypertension associated with severe COPD, nor impact on its increased morbidity and mortality. Exercise intolerance is often improved (temporarily) by lung volume reduction surgery and pulmonary rehabilitation. Ambulatory oxygen is the most effective treatment of exercise limitation. Chronic cigarette smoking is the principal cause of COPD. An early change in smokers' lungs is pulmonary artery intimal thickening and vessel narrowing, which, as COPD develops, is correlated with both the severity of emphysema and bronchiolitis. This may be the consequence of combined smoking-induced apoptosis, inflammation, and imperfect repair. End-stage bronchiolitis and emphysema are likely to limit the effectiveness of bronchodilators and corticosteroids. There are effective treatments for idiopathic and scleroderma pulmonary arterial hypertension, which increase exercise tolerance and improve survival. Because idiopathic and COPD pulmonary hypertension share a common vascular intimal thickening, excess endothelin receptor expression, and plasma endothelin-1, an important therapeutic question to address is whether an oral endothelin-1 antagonist can improve exercise tolerance in severe COPD.

[Diabetes update: preventing type 2 diabetes. Individualized stepwise therapy (oral antidiabetic agents). Multifactorial intervention].

Preclinical disorders of glucose metabolism should be systematically included in the high-risk group for diabetes mellitus and affected individuals provided with preventive measures. Their underlying insulin resistance is determined with the help of a checklist and a method called homeostasis model assessment (HOMA). Patients with impaired fasting glucose (IFG) must change their lifestyles. If this does not lead to a response or the patient is unable to modify behavior, medication is required. In the case of manifest type 2 diabetes mellitus, a graded schedule is used for differential management, which should be based on nutritional and exercise therapy. Oral medication with metformin is probably the drug of choice in both obese and non-obese patients. It is crucial not to delay raising the level of treatment until HbA1c has fallen to within an unsatisfactory range (wait-and-see strategy). Rather, the level should be intensified when persistent exacerbation starts to become apparent (proactive therapy). In diabetes mellitus, the same guidelines for secondary prevention apply to the associated cardiovascular risk factors as with coronary heart disease. An intensified and, especially, early treatment is to be preferred over a conservative, wait-and-see approach, in this case as well.
