Virtual reality exercise intradialysis to improve physical function: A feasibility randomized trial.

Area of Science:

• Nephrology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Patients undergoing hemodialysis often experience physical decline.
• Exercise interventions are crucial for improving physical function in this population.
• Virtual reality (VR) offers a novel approach to intradialysis exercise.

Purpose of the Study:

• To assess the feasibility of an intradialysis non-immersive virtual reality exercise intervention for a future randomized controlled trial (RCT).
• To explore the impact of conventional versus VR exercise on physical function in dialysis patients.

Main Methods:

• A feasibility randomized trial involving 18 subjects undergoing a 16-week intradialysis exercise program.
• Participants were assigned to either a combined exercise or a VR exercise group for an additional four weeks.
• Physical function was assessed using sit-to-stand-to-sit tests, gait speed, one-leg heel-rise, and the 6-minute walk test at baseline and after 20 weeks.

Main Results:

• A significant improvement in physical function was observed in both groups over the 20-week period.
• Improvements were noted in sit-to-stand-to-sit tests (10 and 60), gait speed, left leg one-leg heel-rise, and the 6-minute walk test.
• Adherence rates did not significantly differ between the conventional and VR exercise groups.

Conclusions:

• Non-immersive virtual reality exercise is a feasible intradialysis intervention.
• Both conventional and VR exercise programs effectively enhance physical function in dialysis patients.
• The study supports the integration of VR exercise into dialysis care to improve patient outcomes.
