Quadriceps muscle strength after training with a cycloergometer in patients on hemodialysis

Abstract

Introduction: Functional disability is common in patients with chronic kidney disease, especially in those on hemodialysis. Muscle strength can be evaluated by a dynamometer; however, no study using this technique on the quadriceps of patients undergoing hemodialysis was found in literature. Objective: To assess the effects of cycloergometer training on the quadriceps muscle strength of patients with chronic kidney disease undergoing hemodialysis. Method: This was a clinical trial including 46 patients, both men and women, over 18 years old who had been undergoing hemodialysis for more than six months and signed an informed consent form. Patients were allocated into two groups: intervention group (n = 22) and control group (n = 20). The intervention group underwent intradialytic training in a physical therapy protocol with the cycloergometer for two months, whereas the control group, in turn, was only reevaluated two months after the initial evaluation. All patients were assessed for demographic data at baseline and, two months later for quadriceps muscle strength by standardized dynamometry and with the use of a rigid belt and suction cups. Results: A significant increase was detected in quadriceps muscle strength in the right and left lower limbs in the intervention group when compared with the control group. Conclusion: Quadriceps muscle strength improved after patients with chronic kidney disease on hemodialysis underwent training with the cycloergometer.

Impacto da fisioterapia intradialítica em doentes renais crônicos: uma revisão integrativa

“…O treinamento físico na modalidade intradialítica pode ser realizado de forma segura beneficiando o fortalecimento muscular. Abdo et al [8] avaliaram o impacto do aumento da força de membros inferiores, relacionado ao treino aeróbico com cicloergômetro sem carga incremental, através de um dinamômetro. Os pacientes com DRC submetidos a reabilitação aeróbica tiveram um acréscimo de força, devido ao movimento de pedalar que gera uma tensão sobre as fibras musculares e uma possível alteração no seu metabolismo, o que pode explicar o ganho de força e resistência do músculo quadríceps [8].…”

“…Embora todos os avanços na HD contribuam para melhora na sobrevida dos pacientes, a terapia isoladamente não garante qualidade de vida (QV), devido às limitações implicadas ao quadro urêmico associado [1]. Gerando complicações sistêmicas, metabólicas com prevalências em desordens pulmonares, como a formação de derrames pleurais, hipertensão pulmonar e síndrome do desconforto respiratório agudo, resultado da sobrecarga hídrica apresentada pelo balanço positivo de sódio e toxinas urêmicas circulantes [1,8].…”
