Resistance Exercise in Hemodialysis Patients

The Impact of Resistance Exercise on Symptom Burden in Older Patients Undergoing Maintenance Hemodialysis

The goal of this clinical trial is to learn if an intradialytic resistance exercise intervention works to reduce the symptom burden in older maintenance hemodialysis patients. It will also learn about safety of the intradialytic resistance exercise intervention program. The main questions it aims to answer are:

1. Does intradialytic resistance exercise effectively improve the number, frequency, and severity of symptoms in older patients?
2. What adverse events may occur among older dialysis patients during exercise?

Researchers will compare older dialysis patients who undergo the intradialytic resistance exercise intervention with those receiving standard care to observe whether resistance exercise can improve symptom burden.

Participants will:

1. Take an intradialytic resistance exercise intervention program developed through joint decision-making by rehabilitation experts, dialysis center physicians, nurses, and patients, conducted three times a week for 20 minutes each session, over a duration of three months.
2. Visit the hospital a monthly for texts and examinations.
3. Keep a diary of the types and frequency of adverse events during and after the exercise sessions.
