About this trial
Systemic autoimmune myopathies are rheumatic diseases that affect the striatum skeletal muscles. The transcranial direct current stimulation technique has been frequent, for example, in patients with ischemic stroke or for the optimization of muscular performance in athletes. However, to date, there are no studies evaluating this technique in patients with systemic autoimmune myopathies. Therefore, the main objective of the present prospective, randomized, double-blind, placebo-controlled study is to evaluate the safety and efficacy of the application of chronic transcranial direct current stimulation sessions - associated with aerobic exercises - in the patients with systemic autoimmune myopathies.

Myositis Disease Activity Assessment Visual Analogue Scales (MYOACT)
This partially validated tool measures the degree of disease activity of extra-muscular organ systems and muscle. The questionnaire is a series of physician's assessments of disease activity. Score ranges: 0 (best) - 60 (worst).
Time frame
Six times: (a) Before stimulation; (b) Immediately after all stimulation section; (c) after 30, 60, 90 and 300 days after last stimulation section2
Serum levels of Muscle enzymes
This partially validated tool measures the serum activities of at least 2 of the 4 muscle-associated enzymes including creatine phosphokinase (CK), the transaminases (ALT, AST), lactate dehydrogenase (LD) and aldolase. The reference range value of each muscle enzyme will depend on the laboratory anaysis (kits). International Unit: U/L.
Time frame
Six times: (a) Before stimulation; (b) Immediately after all stimulation section; (c) after 30, 60, 90 and 300 days after last stimulation section3
Health Assessment Questionnaire (HAQ)
Especific questionnaire (health assessment questionnaire). Pontuaction 0.00 (best) - 3.00 (worst)
Time frame
Six times: (a) Before stimulation; (b) Immediately after all stimulation section; (c) after 30, 60, 90 and 300 days after last stimulation section4
Manual Muscle Testing (MMT)
This partially validated tool assesses muscle strength using manual muscle testing (MMT). A 0 - 10 point scale is proposed for use. An abbreviated group of 8 proximal, distal, and axial muscles performs similarly to a total of 24 muscle groups, and is also proposed for use for research studies. Pontuaction: 0 (worst) - 80 (best)
Time frame
Six times: (a) Before stimulation; (b) Immediately after all stimulation section; (c) after 30, 60, 90 and 300 days after last stimulation sectionSponsors and contacts
