The effect of intradialytic resistance exercise on physical function and dialysis adequacy in patients on maintenance hemodialysis
Abstract
Background: Chronic kidney disease poses a growing global health concern and is linked to several complications with higher prevalence and intensity in the hemodialysis (HD) population. These complications contribute to high morbidity and mortality and are associated with poor physical function, and poor quality of life. Intradialytic exercise has emerged as a promising strategy to improve HD patients' clinically relevant outcomes.
Aims: Assess the effect of intradialytic exercise on the functional and metabolic status of patients undergoing HD, and on their physical performance and evaluate its safety and feasibility.
Methods: This was a pre-experimental clinical trial conducted between February and August 2024, including adult patients on maintenance HD at Sahloul University Hospital. Patients underwent a supervised intradialytic resistance training twice or three times a week, over a period of 12 weeks.. Dialysis adequacy parameters, physical function, cardiovascular parameters, as well as patients' nutritional status were assessed before and after the intervention.
Results: Our study included 21 patient with a female predominance (76.2%). The population's mean age was 44.5 ± 10.4 years. A total of five patients (23.8%) received hemodialysis twice a week, while the remaining 16 patients underwent dialysis three times a week. Over the three-month intervention, the six minutes walk test distance improved significantly with a mean paired difference of 26.4 m (p = 0.007). As…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 16 participants or records.
