Feasibility of an Intradialytic Combined Exercise Program Targeting Older Adults With End-Stage Renal Disease

Intradialytic exercise is feasible and yields substantial clinical benefits in middle-aged patients. However, evidence is scarce in older hemodialysis patients.To assess the feasibility and clinical benefits of supervised, intradialytic exercise in older patients.Multicenter one-arm feasibility study. The main outcome was feasibility (ease of recruitment, dropout rate, adherence, affective valence, and adverse events). The secondary outcomes were physical capacity (five-repetition sit-to-stand, 60-s sit-to-stand tests, and grip strength), quality of life (36-Item Short-Form Health Survey), quality of sleep (Pittsburgh Sleep Quality Index), depressive symptoms (Beck Depression Inventory), and dialysis efficacy (Kt/V and urea reduction ratio).About 79% of the screened patients agreed to participate (n = 25, 73 [66-77] years). The dropout rate was high (32%), but adherence remained high among the participants who completed the study (94%). Improvements were found in the five-repetition sit-to-stand (p < .001), 60-s sit-to-stand tests (p = .028), 36-Item Short-Form Health Survey mental component score (p = .008), depressive symptoms (p = .006), and quality of sleep (p = .035).Supervised intradialytic exercise seems safe and beneficial in older patients.
