About this trial
This randomized, assessor-blinded controlled trial will evaluate the preliminary efficacy and safety of a 12-week supervised intradialytic multimodal exercise program for improving postural abnormalities in adults receiving maintenance hemodialysis. Participants will be randomized to either supervised intradialytic exercise plus usual care or usual care alone. The exercise program will be performed three times per week during scheduled hemodialysis sessions and will include postural correction exercises, resistance-band strengthening, core stabilization, stretching, breathing exercises, and seated aerobic cycling. The primary outcome will be change in thoracic kyphosis angle from baseline to Week 12. Secondary outcomes will include craniovertebral angle, balance, mobility, functional exercise capacity, gait speed, physical activity level, adherence, and adverse events. The findings may provide preliminary evidence on the feasibility, safety, and potential clinical value of incorporating postural correction exercises into routine hemodialysis care.
Eligibility criteria
Qualifiers
Age 18-80 years
Diagnosed with ESRD and receiving stable maintenance hemodialysis for at least 3 months at the participating center, with a dialysis frequency of three sessions per week
Confirmed presence of at least one postural abnormality (hyperkyphosis ≥53° in women or ≥55° in men, or CVA <53°) assessed at screening
Written informed consent obtained, indicating decision-making capacity and willingness to participate
Disqualifiers
Unstable cardiovascular status, including recent (within 3 months) myocardial infarction, unstable angina, decompensated congestive heart failure (NYHA Class III-IV), or uncontrolled arrhythmia
Active infection, acute febrile illness, or acute medical condition requiring hospitalization
Hemodynamic instability defined as systolic blood pressure <90 mmHg or >200 mmHg, or severe orthostatic hypotension, at screening or prior to exercise sessions
Uncontrolled diabetes mellitus with labile glycemic control (blood glucose <4 mmol/L or >22 mmol/L at dialysis session start)
