RESUMO
OBJECTIVES: Transcranial direct current stimulation (tDCS) combined with aerobic exercise (tDCS-AE) effectively reduces fatigue in patients with fibromyalgia. However, no study has assessed this method in systemic lupus erythematosus (SLE) patients with significant fatigue. Therefore, we evaluated the safety and efficacy of tDCS-AE for significant fatigue symptoms in adult female SLE patients. METHODS: This randomised, sham-controlled, double-blind study included 25 patients with SLE in remission or low disease activity (SLEDAI-2K £4) and with significant fatigue [≥36 points on the Fatigue Severity Scale (FSS) or ≥38 points on the Modified Fatigue Scale (MFIS)]. The patients received sham or tDCS for five consecutive days. The anode and cathode were positioned at M1 and Fp2, respectively (international 10-20 EEG system). tDCS was applied at an intensity of 2mA, and density of 0.057mA/cm2 in the tDCS-AE group. Both groups underwent combined low-intensity treadmill exercise. FSS, MFIS, pain visual analogue scale, physical activity, and sleep quality were evaluated at baseline and on days 7, 30, and 60. Adherence and safety were assessed using a standardised questionnaire. RESULTS: Improvement in fatigue levels was observed in both groups. However, a sustained reduction in fatigue levels on days 30 and 60 occurred only with tDCS-AEs (p<0.05). No significant differences were observed in pain level, sleep quality, or physical activity. No disease flares occurred and the adverse effects were mild and transient. Finally, the patient's adherence to the treatment was satisfactory. CONCLUSIONS: Despite isolated AEs, there was an improvement in fatigue, however, only tDCS-AE maintained significant and sustained improvement.

OBJECTIVES: We aimed to assess the safety and efficacy of transcranial direct current stimulation (tDCS) in patients with systemic autoimmune myopathies (SAMs). METHODS: This prospective, randomised, sham-controlled, double-blind, study included 20 patients with SAMs allocated to receive sham or active tDCS (2mA, 20 minutes, 3 days). Electrodes were positioned with the anode over the C1 or C2, whereas the cathode was placed over the Fp2 or Fp1, respectively. The groups were evaluated in four periods with specific questionnaires and functional tests: pre-stimulation and after 30 minutes, three weeks, and eight weeks post-tDCS. RESULTS: Two patients from the sham group withdrew after the three sessions. The demographic data, type of myositis, disease duration, and disease status were comparable between the active and sham tDCS groups. After interventions, in the active tDCS group, the physical aspects of SF-36 in week eight, mean and better timed up-and-go test at each evaluation, peak torque of stimulated inferior limb extension improved significantly (p<0.05). The emotional aspect of SF-36 decreased only in the active tDCS group (p<0.001). The patients' adherence to the protocol was 100% and no serious adverse event was reported, including disease relapses. CONCLUSIONS: This study evidences the safety of tDCS, as well as its potential efficacy in improving muscle strength and function in SAMs patients. More studies with a larger sample and longer tDCS sessions are necessary to corroborate the results of the present study.

Os autores apresentaram estudo epidemiológico basedo na análise dos caso com lesöes traumáticas da coluna vertebral internados no Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da FMUSP de 1982 a 1987. Dos 428 pacientes 94,3% eram do sexo masculino, estando predominantemente na faixa etária de 21 a 30 anos. O nível mais freqüênte da lesäo foi na regiäo cervical, com déficit neurológico do tipo completo. Os tipos de acidente ou violência mais freqüentes foram os ferimentos por arma de fogo e a seguir os acidentes de tránsito. A freqüência de óbito foi de 21% principalmente por problemas respiratórios
