Abstract
BACKGROUND Strength training or aerobic exercise programmes, or both, might optimise muscle and cardiorespiratory function and prevent additional disuse atrophy and deconditioning in people with a muscle disease. This is an update of a review first published in 2004 and last updated in 2013. We undertook an update to incorporate new evidence in this active area of research. OBJECTIVES To assess the effects (benefits and harms) of strength training and aerobic exercise training in people with a muscle disease. SEARCH METHODS We searched Cochrane Neuromuscular's Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL in November 2018 and clinical trials registries in December 2018. SELECTION CRITERIA Randomised controlled trials (RCTs), quasi-RCTs or cross-over RCTs comparing strength or aerobic exercise training, or both lasting at least six weeks, to no training in people with a well-described muscle disease diagnosis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included 14 trials of aerobic exercise, strength training, or both, with an exercise duration of eight to 52 weeks, which included 428 participants with facioscapulohumeral muscular dystrophy (FSHD), dermatomyositis, polymyositis, mitochondrial myopathy, Duchenne muscular dystrophy (DMD), or myotonic dystrophy. Risk of bias was variable, as blinding of participants was not possible, some trials did not blind outcome assessors, and some did not use an intention-to-treat analysis. Strength training compared to no training (3 trials) For participants with FSHD (35 participants), there was low-certainty evidence of little or no effect on dynamic strength of elbow flexors (MD 1.2 kgF, 95% CI -0.2 to 2.6), on isometric strength of elbow flexors (MD 0.5 kgF, 95% CI -0.7 to 1.8), and ankle dorsiflexors (MD 0.4 kgF, 95% CI -2.4 to 3.2), and on dynamic strength of ankle dorsiflexors (MD -0.4 kgF, 95% CI -2.3 to 1.4). For participants with myotonic dystrophy type 1 (35 participants), there was very low-certainty evidence of a slight improvement in isometric wrist extensor strength (MD 8.0 N, 95% CI 0.7 to 15.3) and of little or no effect on hand grip force (MD 6.0 N, 95% CI -6.7 to 18.7), pinch grip force (MD 1.0 N, 95% CI -3.3 to 5.3) and isometric wrist flexor force (MD 7.0 N, 95% CI -3.4 to 17.4). Aerobic exercise training compared to no training (5 trials) For participants with DMD there was very low-certainty evidence regarding the number of leg revolutions (MD 14.0, 95% CI -89.0 to 117.0; 23 participants) or arm revolutions (MD 34.8, 95% CI -68.2 to 137.8; 23 participants), during an assisted six-minute cycle test, and very low-certainty evidence regarding muscle strength (MD 1.7, 95% CI -1.9 to 5.3; 15 participants). For participants with FSHD, there was low-certainty evidence of improvement in aerobic capacity (MD 1.1 L/min, 95% CI 0.4 to 1.8, 38 participants) and of little or no effect on knee extension strength (MD 0.1 kg, 95% CI -0.7 to 0.9, 52 participants). For participants with dermatomyositis and polymyositis (14 participants), there was very low-certainty evidence regarding aerobic capacity (MD 14.6, 95% CI -1.0 to 30.2). Combined aerobic exercise and strength training compared to no training (6 trials) For participants with juvenile dermatomyositis (26 participants) there was low-certainty evidence of an improvement in knee extensor strength on the right (MD 36.0 N, 95% CI 25.0 to 47.1) and left (MD 17 N 95% CI 0.5 to 33.5), but low-certainty evidence of little or no effect on maximum force of hip flexors on the right (MD -9.0 N, 95% CI -22.4 to 4.4) or left (MD 6.0 N, 95% CI -6.6 to 18.6). This trial also provided low-certainty evidence of a slight decrease of aerobic capacity (MD -1.2 min, 95% CI -1.6 to 0.9). For participants with dermatomyositis and polymyositis (21 participants), we found very low-certainty evidence for slight increases in muscle strength as measured by dynamic strength of knee extensors on the right (MD 2.5 kg, 95% CI 1.8 to 3.3) and on the left (MD 2.7 kg, 95% CI 2.0 to 3.4) and no clear effect in isometric muscle strength of eight different muscles (MD 1.0, 95% CI -1.1 to 3.1). There was very low-certainty evidence that there may be an increase in aerobic capacity, as measured with time to exhaustion in an incremental cycle test (17.5 min, 95% CI 8.0 to 27.0) and power performed at VO2 max (maximal oxygen uptake) (18 W, 95% CI 15.0 to 21.0). For participants with mitochondrial myopathy (18 participants), we found very low-certainty evidence regarding shoulder muscle (MD -5.0 kg, 95% CI -14.7 to 4.7), pectoralis major muscle (MD 6.4 kg, 95% CI -2.9 to 15.7), and anterior arm muscle strength (MD 7.3 kg, 95% CI -2.9 to 17.5). We found very low-certainty evidence regarding aerobic capacity, as measured with mean time cycled (MD 23.7 min, 95% CI 2.6 to 44.8) and mean distance cycled until exhaustion (MD 9.7 km, 95% CI 1.5 to 17.9). One trial in myotonic dystrophy type 1 (35 participants) did not provide data on muscle strength or aerobic capacity following combined training. In this trial, muscle strength deteriorated in one person and one person had worse daytime sleepiness (very low-certainty evidence). For participants with FSHD (16 participants), we found very low-certainty evidence regarding muscle strength, aerobic capacity and VO2 peak; the results were very imprecise. Most trials reported no adverse events other than muscle soreness or joint complaints (low- to very low-certainty evidence). AUTHORS' CONCLUSIONS The evidence regarding strength training and aerobic exercise interventions remains uncertain. Evidence suggests that strength training alone may have little or no effect, and that aerobic exercise training alone may lead to a possible improvement in aerobic capacity, but only for participants with FSHD. For combined aerobic exercise and strength training, there may be slight increases in muscle strength and aerobic capacity for people with dermatomyositis and polymyositis, and a slight decrease in aerobic capacity and increase in muscle strength for people with juvenile dermatomyositis. More research with robust methodology and greater numbers of participants is still required.

Abstract
BACKGROUND Polymyositis (PM) and Dermatomyositis (DM) are chronic, inflammatory and autoimmune skeletal muscle disorders characterized by reduced muscle strength, fatigue and myalgia. While inflammation causes muscle damage in the early phase, metabolic alterations such as an impairment of oxidative metabolism seem to be responsible for the disability in the chronic phase of the disease. AIM To assess muscle oxidative efficiency and to test the effect of aerobic training in a group of PM/DM patients. DESIGN A case-control study and a within-group comparison. SETTING. Outpatients of the Unit of Neurorehabilitation of the University Hospital of Pisa. POPULATION 20 patients with myositis (15 PM and 5 DM) and 15 healthy subjects as a control group. METHODS The test consisted of an incremental, sub-maximal aerobic exercise on a treadmill; haematic lactate was assessed at rest and after 1', 5', 10' and 30' minutes from the end of the exercise. A within-group comparison was conducted on four of the PM patients (P group). They were subjected to six weeks aerobic training. Lactate curve and functional tests were assessed before and after the treatment. RESULTS A precocious fatigability and significantly higher values of lactate at rest and after the exercise were observed in patients. In the P group mean lactate levels were significantly decreased after the treatment and an improvement of muscle performance was observed. CONCLUSION Abnormal blood lactate levels suggested an impaired muscle oxidative efficiency in PM/DM patients. A specific aerobic training program reduced lactate levels and relieved fatigue symptoms in a within-group of four of the PM patients. CLINICAL REHABILITATION IMPACT Such a specific aerobic training program could be introduced in everyday practice for the rehabilitative treatment of PM/DM patients.

Abstract
BACKGROUND Strength training or aerobic exercise programmes might optimise muscle and cardiorespiratory function and prevent additional disuse atrophy and deconditioning in people with a muscle disease. This is an update of a review first published in 2004. OBJECTIVES To examine the safety and efficacy of strength training and aerobic exercise training in people with a muscle disease. SEARCH METHODS We searched the Cochrane Neuromuscular Disease Group Specialized Register (July 2012), CENTRAL (2012 Issue 3 of 4), MEDLINE (January 1946 to July 2012), EMBASE (January 1974 to July 2012), EMBASE Classic (1947 to 1973) and CINAHL (January 1982 to July 2012). SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing strength training or aerobic exercise programmes, or both, to no training, and lasting at least six weeks, in people with a well-described diagnosis of a muscle disease.We did not use the reporting of specific outcomes as a study selection criterion. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted the data obtained from the full text-articles and from the original investigators. We collected adverse event data from included studies. MAIN RESULTS We included five trials (170 participants). The first trial compared the effect of strength training versus no training in 36 people with myotonic dystrophy. The second trial compared aerobic exercise training versus no training in 14 people with polymyositis and dermatomyositis. The third trial compared strength training versus no training in a factorial trial that also compared albuterol with placebo, in 65 people with facioscapulohumeral muscular dystrophy (FSHD). The fourth trial compared combined strength training and aerobic exercise versus no training in 18 people with mitochondrial myopathy. The fifth trial compared combined strength training and aerobic exercise versus no training in 35 people with myotonic dystrophy type 1.In both myotonic dystrophy trials and the dermatomyositis and polymyositis trial there were no significant differences between training and non-training groups for primary and secondary outcome measures. The risk of bias of the strength training trial in myotonic dystrophy and the aerobic exercise trial in polymyositis and dermatomyositis was judged as uncertain, and for the combined strength training and aerobic exercise trial, the risk of bias was judged as adequate. In the FSHD trial, for which the risk of bias was judged as adequate, a +1.17 kg difference (95% confidence interval (CI) 0.18 to 2.16) in dynamic strength of elbow flexors in favour of the training group reached statistical significance. In the mitochondrial myopathy trial, there were no significant differences in dynamic strength measures between training and non-training groups. Exercise duration and distance cycled in a submaximal endurance test increased significantly in the training group compared to the control group. The differences in mean time and mean distance cycled till exhaustion between groups were 23.70 min (95% CI 2.63 to 44.77) and 9.70 km (95% CI 1.51 to 17.89), respectively. The risk of bias was judged as uncertain. In all trials, no adverse events were reported. AUTHORS' CONCLUSIONS Moderate-intensity strength training in myotonic dystrophy and FSHD and aerobic exercise training in dermatomyositis and polymyositis and myotonic dystrophy type I appear to do no harm, but there is insufficient evidence to conclude that they offer benefit. In mitochondrial myopathy, aerobic exercise combined with strength training appears to be safe and may be effective in increasing submaximal endurance capacity. Limitations in the design of studies in other muscle diseases prevent more general conclusions in these disorders.

Abstract
OBJECTIVE To compare muscle fiber type composition and muscle fiber area in patients with chronic polymyositis or dermatomyositis and healthy controls, and to determine whether physical training for 12 weeks could alter these muscle characteristics. METHODS Muscle fiber type composition and muscle fiber area were investigated by biochemical and immunohistochemistry techniques in repeated muscle biopsy samples obtained from 9 patients with chronic myositis before and after a 12-week exercise program and in healthy controls. Muscle performance was evaluated by the Functional Index (FI) in myositis and by the Short Form 36 (SF-36) quality of life instrument. RESULTS Before exercise, the proportion of type I fibers was lower (mean +/- SD 32% +/- 10%) and the proportion of type IIC fibers was higher (3% +/- 3%) in patients compared with healthy controls. After exercise, percentage of type I fiber increased to 42% +/- 13% (P < 0.05), and type IIC decreased to 1% +/- 1%. An exercise-induced 20% increase of the mean fiber area was also observed. The functional capacity measured by the FI in myositis and the physical functioning subscale of the SF-36 increased significantly. Improved physical functioning was positively correlated with the proportion of type I fibers (r = 0.88, P < 0.01) and type II muscle fiber area (r = 0.70, P < 0.05). CONCLUSION Low muscle endurance in chronic polymyositis or dermatomyositis may be related to a low proportion of oxidative, slow-twitch type I fibers. Change in fiber type composition and increased muscle fiber area may contribute to improved muscle endurance and decreased muscle fatigue after a moderate physical training program.

Abstract
OBJECTIVE To investigate the benefits and safety of an intensive muscular training program in patients with chronic polymyositis (PM) and dermatomyositis (DM). METHODS Nine patients with chronic PM or DM (median age 53 years, range 44-61) were included. Assessments of impairment (10-15 voluntary repetition maximum [VRM], the Functional Index 2 [FI-2], the Grippit, and pain rated on the Borg CR-10 scale), activity limitation (Myositis Activities Profile), and participation restriction (patients' disease impact on well-being) were performed 4 weeks prior to baseline, at baseline, and after 7 weeks of exercise. A 6-item core set of disease activity measures was administered and muscle biopsy samples of vastus lateralis were obtained at baseline and after 7 weeks of exercise. Response criteria at an individual level were set for disability and disease activity. The patients exercised 3 days per week for 7 weeks on loads allowing 10 VRM. RESULTS On a group level there were no significant differences between assessments at 4 weeks before baseline compared with baseline. The group improved significantly regarding 10-15 VRM and FI-2 at 7 weeks compared with baseline (P < 0.05). All patients were responders with respect to impairment and 2 were activity limitation responders whereas participation restriction remained unchanged in all. Two patients were responders with reduced disease activity and no patient had signs of increased muscle inflammation in the muscle biopsy sample after 7 weeks of exercise. CONCLUSION Patients with chronic, stable PM and DM can perform this intensive resistive exercise program with beneficial effects on impairment and activity limitation without increased muscle inflammation.

Abstract
Polymyositis and dermatomyositis (PM/DM) are representative inflammatory muscle diseases. In treatment of PM/DM, drug therapies are cardinal but rehabilitation may be another option. Since muscles with PM/DM are fragile for muscle exercise, rehabilitation has been recommended mainly in chronic phase. Some researchers considered that rehabilitation for PM/DM patients in acute phase may improve their functional prognosis without major sideeffect. However, there are controversies about rehabilitation for PM/DM patients from acute phase. To consider advisability, I reviewed literatures concerning rehabilitation for PM/DM patients in acute phase.

Abstract
PURPOSE OF REVIEW Juvenile dermatomyositis is a rare chronic inflammatory disease that primarily affects the muscles and skin. Immunosuppressive therapy has played a very important role in reducing mortality rates and morbidity. The review focuses on the spectrum of medications currently used in the treatment of juvenile dermatomyositis, highlighting new advances and unanswered questions. RECENT FINDINGS Data regarding the treatment of juvenile dermatomyositis come almost entirely from retrospective studies with relatively small numbers of patients. Corticosteroids continue to be the accepted first-line therapy. Evidence that the addition of methotrexate at initiation of treatment allows corticosteroids to be tapered more rapidly with good outcomes exists. High-risk, refractory patients may benefit from intravenous cyclophosphamide. Results in refractory patients treated with rituximab are also encouraging. Topical immunosuppressant agents have been largely disappointing in treating rash. The effect and role of exercise in the treatment and rehabilitation of patients with juvenile dermatomyositis is an interesting new area of research. SUMMARY Future research in the treatment of juvenile dermatomyositis should focus on improving the understanding of disease course and its predictors such that treatment protocols can be developed to provide the most benefit and least amount of medication toxicity for the individual patient.

Abstract
OBJECTIVES To present the outcome of patients with idiopathic inflammatory myositis, focusing on functional ability and quality of life. METHODS Analysis was performed using data from 105 adult patients with definitive polymyositis, dermatomyositis or overlap myositis, who were followed up at a single centre. The diagnosis was made between 1979 and 2000 based on Bohan and Peter's criteria. Functional ability was assessed after a minimum follow-up of 3 yr with the Health Assessment Questionnaire Disability Index (HAQDI) and quality of life was measured with the Short Form 36-item questionnaire (SF-36). RESULTS Fifteen patients in our cohort died and 87 participated in the evaluation of functional outcome. Functional ability after a median follow-up of 107.1 months (range 36.4-273.3) was heterogeneous. The median HAQDI score was 0.875 (range 0-2.875). Polyphasic or chronic-progressive disease course, osteoporosis and long-term follow-up were predictive of higher HAQDI scores. In terms of quality of life, significant differences from population norms were shown in all domains of the SF-36. There were no significant differences in the SF-36 scores among the patients according to clinicopathological subset or disease course. CONCLUSIONS Although the mortality of our cohort was favourable, myositis continues to have a great impact on life in the medium and long term. The present work indicates that myositis patients have a significantly poorer quality of life than the normal population, but there was no difference among the patients according to clinicopathological subsets.

Abstract
Physical exercise plays a crucial role in the treatment of inflammatory myopathies. In the phase of active muscle inflammation the prevention of contractures in the joints and physiotherapy for the respiratory system are the most important goals, whereas in the recovery phase of dermatomyositis and polymyositis the emphasis must be on the strengthening of the remaining muscle fibers and the treatment of the myopathy caused by corticosteroids. The authors discuss in detail the special rehabilitation problems of myositis patients depending on the activity and subtype of the disease and the possible solutions.

Abstract
OBJECTIVE To study the effect of physical exercise shortly after an acute episode of dermato/polymyositis (DM/PM). DESIGN Pilot study of a descriptive nature. SETTING Rehabilitation unit of a large general hospital. SUBJECTS Ten patients 2-3 weeks after an acute phase of DM/PM (early recovery group) and 11 patients in the inactive stage of DM/PM for at least three months (chronic stage group). INTERVENTIONS Isotonic muscle training consisted of several series of different repeated movements at 65-70% of individual maximal repetition limit. Special training was applied for the respiratory muscles. Relaxing baths, mud packs and massages were also applied. OUTCOME MEASURES Dynamometer and spirometer were used for measuring the changes in muscle strength and respiratory function. Disability tests were done before and after therapy. RESULTS No disease relapses or decreases in muscle function were seen. In the early recovery group, the average muscle strength improvement was 17 +/- 31 % (p > 0.05) in the proximal muscles and 37 +/- 23% (p < 0.05) in the distal muscles, while the vital capacity also increased by 17 +/- 21% (p < 0.05). In the chronic stage group the average improvement in muscle strength was 46 +/- 34% (p < 0.05) in the proximal muscles and 37 +/- 29% (p < 0.05) in the distal muscles. By the end of the therapy both groups showed improvements in disability tests (p < 0.05). CONCLUSIONS Physical training started 2-3 weeks following an acute exacerbation of the disease seems to be useful and safe. Some improvement in muscle strength and respiratory function can be obtained, muscle atrophy due to inactivity may be partially prevented and the level of disability can be decreased.

Abstract
The clinical features of inflammatory myositis are determined by the severity and extent of muscle weakness and systemic manifestations. The benefits and limitations of physical training programs and rehabilitation strategies depend on the clinical phase of the disease and analysis of underlying impairments responsible for functional limitations in the patient. Patients with early stage disease and severe weakness will be treated differently than patients who have responded to medication and are improving. Not all patients will respond to medications; their therapy programs will have different requirements. This article reviews available data on the physiologic responses to exercise in patients with inflammatory muscle diseases. New data support more aggressive approaches to progressive strengthening exercises for patients with inflammatory myositis.

Abstract
OBJECTIVE During the last few years, in an attempt to reduce the side effects of glucocorticoid (GC) therapy, we have been treating polymyositis-dermatomyositis (PM-DM) patients with a lower starting dose of GC than is classically recommended. In order to validate this approach, we performed a functional re-evaluation of these PM-DM patients. METHODS A comprehensive protocol evaluating muscle strength, muscle function, CK levels, persistence of spontaneous activity on electromyography, disability in daily life activities and degree of dependence was applied in 25 non-cancer-associated biopsy-proven PM-DM patients, 15 of whom had been treated with a high-dose regimen (i.e. > 0.5 mg prednisolone/kg/day) and 10 with a low-dose regimen (i.e. < or = 0.5 mg prednisolone/kg/day). RESULTS Our results indicate that the functional outcome of PM-DM patients given a low-dose starting regimen of GC does not differ from that observed in patients given higher doses. Interestingly, vertebral fractures were less common in patients treated with lower GC doses. CONCLUSIONS Although our analysis has certain shortcomings, including the small number of patients investigated and their uncontrolled assignment to a low-dose or a high-dose GC regimen, the results of this retrospective study suggest that a low-dose starting regimen of GC can achieve a good functional outcome in PM-DM patients, with a reduction of treatment-related disability. This approach would be welcome as a step forward should it be validated by a longitudinal study.

Abstract
OBJECTIVE The benefit of long-term physical training in patients with chronic polymyositis or dermatomyositis (PM/DM) was studied prospectively. METHODS Eight patients with chronic PM/DM participated in a training programme for 6 months. A group of five PM/DM patients without any physical training was observed for control purposes. RESULTS While there was no significant change in serum creatine phosphokinase (CPK) levels, the 'activities of daily living (ADL)' score improved significantly (P < 0.03), peak isometric torque (PIT) generated by muscle groups in the lower extremities rose significantly (P < 0.03) and there was a statistically highly significant increase in peak oxygen uptake (VO2max) relative to body weight (P < 0.02) due to the long-term training. The patients improved their aerobic capacity by 28%, which is clinically significant. In the untrained patients, no improvement in these target parameters was observed. CONCLUSION In clinically stable DM/PM patients, long-term physical training can safely be performed and is recommended as part of a comprehensive rehabilitation management, particularly in view of the cardiopulmonary risk in these patients.

Abstract
Myopathies, regardless of their varied etiologies, are associated with muscle damage and, often, other organ system involvement causing physical impairment. The resultant adverse impact on mobility, activities of daily living, communication, and cardiorespiratory fitness results in disability, handicap, and reduced quality of life. The extent of the functional impact depends on the type of myopathy and the extent of clinical involvement caused by it, duration of the disease, time to diagnosis and treatment, and rate of progression and response to medical management. The usefulness of rehabilitation in maintaining function in muscular dystrophy has been addressed in the literature for several decades. However, the need for and efficacy of specific rehabilitation interventions and assessment tools to measure function in inflammatory myopathy have just recently emerged this decade. Although studies are few in number, they are useful. More research is needed and should be encouraged. The overall goal of rehabilitation is to enhance function and quality of life.

Abstract
In the present investigation, the benefit of physical training in patients with inflammatory myopathy was studied. In this prospective, randomized, controlled study, 14 patients with polymyositis (PM) or dermatomyositis (DM) were investigated. The training, consisting of bicycle exercise and step aerobics, took place over a 6 week period. Baseline and endpoint measurements included an 'activities of daily living' (ADL) score, peak isometric torque (PIT) generated by muscle groups in the lower extremities, peak oxygen consumption (VO2max), and creatine phosphokinase (CPK) levels. There was no significant rise in disease activity in the training group in comparison to the controls. The ADL score for the treatment group, in comparison to the control group, improved (P < 0.02), PIT rose (P < 0.05) and there was a statistically significant increase in oxygen uptake relative to body weight (P < 0.05). No rise in inflammatory activity, but significant improvement in muscle strength, oxygen uptake and well-being, were found in patients with inflammatory myopathy as a result of physical training. Besides medication, a physical training programme consisting mainly of concentric muscle contractions should therefore be an integral part of therapy, particularly in view of the cardiopulmonary risk of these patients.

Abstract
This article reviews the current status of the classification and treatment of the juvenile idiopathic inflammatory myopathies. The intent of classification is to define homogeneous groups that share similar clinical features, disease courses, and responses to therapy. The classification scheme proposed includes clinicopathologic subsets, serologic subjects based on the presence of myositis-specific and myositis-associated autoantibodies, and environmental triggers of myositis. Juvenile dermatomyositis is the most common and widely recognized of these disorders. The second part reviews the history of treatment of juvenile dermatomyositis and discusses agents to consider for patients with refractory disease, unacceptable steroid toxicity, or poor prognostic factors.

Abstract
This article discusses the principles of rehabilitation of the most common childhood rheumatic diseases, especially juvenile rheumatoid arthritis, dermatomyositis, and scleroderma. Any rehabilitation program must be undertaken in conjunction with understanding of disease processes, appropriate medical management, and patient and family education. Investing effort into avoiding contractures, weakness, osteoporosis, and disability is considerably less time-consuming, painful, and costly than trying to reverse established problems.

Abstract
OBJECTIVE To determine the effect of a resistive exercise program in the rehabilitation of patients with polymyositis/dermatomyositis (PM/DM). METHODS Five patients participated in a rehabilitation program that included resistive exercises. In 4 of the patients, these exercises were randomly alternated with nonresistive exercise. Each type of exercise was assigned for periods of 2 weeks, and at the end of each one, muscle strength was measured by means of manual muscle testing (MMT), an activities of daily living (ADL) score, and peak isometric torque (PIT) generated by muscle groups in the lower extremities. Creatine phosphokinase (CPK) levels were used to measure disease activity. The acute response to resistive exercise was studied in 4 of the patients by measuring serial levels of CPK following a session on an exercise bicycle. RESULTS Of the 4 patients who participated in both types of exercises, 3 experienced increases in strength during both resistive and nonresistive exercise periods. The patient who participated only in resistive exercises had considerable improvements in muscle strength. One patient made no improvements in strength with either type of exercise. None of the patients experienced clinically significant elevations in CPK attributable to either type of exercise. Following a session of resistive exercise, the mean CPK elevation in 4 patients was 7.7%, returning to pre-exercise levels by 8 h in all cases. CONCLUSIONS Patients with PM/DM may participate in a rehabilitation program which includes resistive exercises. Such programs may be accompanied by increased strength without clinically significant rises in serum levels of muscle enzymes.
