Not Applicable
Not yet recruiting
Conditions
Hemodialysis
Interventions
Behavioral: Resistance exercise intervention
Behavioral: Routine care
Registration Number
NCT06604221
Lead Sponsor
Teng Zeng
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Dialysis Symptom IndexFrom enrollment to the end of treatment at 12 weeks

Kidney failure-related symptoms were assessed every month using the dialysis symptom index (DSI), a previously validated questionnaire Through this questionnaire, patients indicated the presence of 30 symptoms in the past month, resulting in a total sum score for symptom number ranging from 0 to 30. Additionally, for each symptom present, patients rated symptom burden on a five-point Likert scale, ranging from one for "not at all" to five for "very much" burdensome. Absent symptoms were assigned a score of zero, resulting in an overall symptom burden score ranging from zero to 150, with higher scores indicating larger burden.

Secondary Outcome Measures
NameTimeMethod
30 Seconds Sit To Stand TestFrom enrollment to the end of treatment at 12 weeks

A chair with a hard seat whose floor-to-seat height was 48 cm was stabilized by placing it against a wall. After a researcher explained the requirements and precautions to the participant, the participant was asked to sit with his or her feet exactly flat on the ground and his or her upper limbs folded across his or her chest and then to stand up all the way and sit down again without using his or her arms. And the participant was asked to repeat as many of the sit-to-stand actions as possible in 30 seconds, and the maximum number completed was recorded.

Higher scores mean a better outcome.

Short Physical Performance BatteryFrom enrollment to the end of treatment at 12 weeks

(SPPB) which consists of 3 timed components: 1) a 4-meter usual pace walk, 2) a five-repetition chair stand without using one's arms, and 3) a progressive test of standing balance. Times from each component were scored from 0-4, with higher scores corresponding to better performance.

Number of participants with abnormal laboratory tests resultsFrom enrollment to the end of treatment at 12 weeks

blood urea, blood creatinine, dialysis adequacy (Kt/V), hemoglobin, neutrophil-to-lymphocyte ratio, serum albumin, standardized protein catabolic rate, C-reactive protein, inflammatory factors
