Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic kidney disease is a systemic disease that affects not only renal function, but also, several organs, bringing social, psychological and physical impact to the patients under this condition. Due to long periods of inactivity during hemodialysis, electrical stimulation becomes a feasible alternative for development physical activity in these patients. Objective: Assess the efficacy of combined low and high frequency electrical stimulation in peripheral muscle function during hemodialysis. Methods: A randomised double-blind clinical trial with chronic kidney disease patient's under hemodialysis, whose will be allocated in four groups: low frequency electrical stimulation (LF) ; high frequency (HF); low and high frequency (LHF); and sham electrical stimulation. The groups will receive quadriceps application bilaterally, for sixty minutes, three times a week, for two months. In the intervention groups will be used highest intensity tolerated by the individual, and in the sham will be maintained the minimum intensity after beginning of the perception of the electric current. The individuals will be evaluated for anthropometry, functional capacity, quality of life and biochemical parameters.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients in the present study will be submitted to an evaluation protocol that must be started after the consent of the responsible medical team, and the patient through the Informed Consent Term. On the first day, patients will be evaluated for their personal antecedents, life habits, inflammatory and nutritional status, quality of life, Medical Research Council (MRC) and biochemical markers. On the second day, anthropometry, body composition and functional capacity will be performed. On the third day, the muscular function will be assessed by isokinetic evaluation. After completing the evaluations, patients will be allocated into four groups: low frequency (LF), high frequency (HF), low and high frequency (LHF), and sham.
