Bioeletric Stimulation in Patients With Chronic Kidney Failure

Status Not yet recruiting

Clinical Trial Summary

This study aims to evaluate the effects of electrical stimulation on renal function and physical capacity in patients with chronic kidney disease (CKD). This is a randomized controlled trial with patients from the HD outpatient of Santa Clara hospital at Irmandade Santa Casa de Misericórdia de Porto Alegre (ISCMPA), who will be allocated to a control group (it will be evaluated and reassessed) or intervention group (it will receive electrical stimulation). Interventions will occur during the HD session, twice a week, for eight weeks, totaling 16 sessions. The groups will be evaluated prior to physiotherapy intervention and at the end. The following outcomes will be measured: renal function, functional capacity, muscle strength of lower limbs and quality of life.

Clinical Trial Description

Chronic kidney disease consists of kidney damage, with consequent progressive and irreversible loss of kidney function. Lower circulating levels of α-klotho protein are related to worsening kidney function and as it is affected, systemic changes occur and lead to the involvement of other organs. Supplementation of soluble α-Klotho protein carried out in experimental studies has been shown to be effective in protecting renal function, in addition to slowing the progression of CKD. Endogenously, physical exercise seems to be a way to increase circulating levels of α klotho. In addition, it is suggested that the contractile activity of the skeletal muscle modulates the expression of circulating Klotho. The practice of physical exercise is considered fundamental in the treatment of patients with CKD, since they present loss of muscle mass and decline in muscle function, and consequently low rates of physical activity and physical inactivity, which is strongly associated with mortality in this population. As an alternative to mitigate the deleterious effects of sarcopenia in this population, studies have shown beneficial effects of electrical stimulation, such as increased muscle strength, functional capacity and protection against muscle atrophy of the lower limbs. In addition to the clinical and functional effects, electrostimulation reduces DNA damage in patients on hemodialysis (HD), suggesting that electrical stimulation has a systemic effect. In this context, the aim of this study is to evaluate the effects of electrical stimulation on renal function and physical capacity in patients with CKD on HD. The sample will consist of 20 patients of both sexes, with CKD in stage V of the DRC recruited from the HD outpatient of Santa Clara hospital at ISCMPA. Patients will be randomized into an control or electrical stimulation group. The control group will be evaluated and reassessed. Evaluations will be carried out before and after follow-up: analysis of the plasma content of soluble α-Klotho and creatinine to assess renal function, six-minute walk test (6MWT) to assess functional capacity, sit-and-stand test (STS) with 10 repetitions and dynamometry per load cell to assess muscle strength of lower limbs and application of the EuroQoL-5D questionnaire for quality of life. Electrical stimulation will be performed during HD, twice a week, for eight weeks, totaling 16 sessions. In the same session, a protocol of neuromuscular electrical stimulation will be applied to quadriceps muscle for 20 min. After, a protocol of sensory electrical stimulation will be applied on kidney anatomical region for 45 min. At the end of the study, is expected from patients who received electrical stimulation an increase in kidney function and improvement on physical capacity, muscle strength and quality of life. ;
