Chronic Kidney Diseases Hemodialysis | Behavioral: Intradialytic exercise intervention Behavioral: Usual Care | Not Applicable |
The primary objective of this trial is to assess the effectiveness of intradialytic exercise training (ET) and health literacy counselling (HLC) over 12 months intervention in patients undergoing chronic outpatient hemodialysis as compared to usual care (UC). The primary endpoint is change in Sit-to-Stand (STS60) test, from baseline to after 12 months intervention. The ET consists of both resistance and endurance training, focusing on improving patients' health status and physical functioning. Health literacy counseling aims at improving education, proficiency and self-awareness of the patient.
All patients undergoing hemodialysis in participating centers (clusters) for at least four weeks are eligible to participate in the study. Irrespective of randomized center (cluster) group assignment, all dialysis and overall medical treatments will remain unchanged and follow standard of care and center routine without adaptations to the training intervention.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 1211 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Random assignment in 1:1 ratio into either intervention group (12 months intradialytic exercise intervention; 50% aerobic exercise, 50% resistance training; thrice a week for 60 min per dialysis session) and health literacy counselling (HLC) or control group/usual care (Usual care without any exercise intervention or HLC) |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | Exercise During Hemodialysis: The Dialysis Training Therapy (DiaTT) Trial |
