In a recent study, a simple exercise program carried out at home improved dialysis patients' walking performance and quality of life.
Published in the Journal of American Society of Nephrology (JASN), the study included 296 dialysis patients.
The team randomized normal physical activity or a low intensity exercise program--20 minutes of walking at low-moderate speed every second day--of gradually increasing intensity over 6 months.
After 6 months, the distance covered during a 6-minute walking test improved in the exercise group (average distance: baseline 328 m; 6 months 367 m) but not in the control group (baseline 321 m; 6 months 324 m).
Similarly, the 5 times sit-to-stand test time improved in the exercise group average time: baseline 20.5 seconds; 6 months 18.2 seconds) but not in the control group (baseline 20.9 seconds; 6 months 20.2 seconds).
Cognitive function and quality of scores improved significantly in the exercise arm compared with the control arm.
"Poor physical functioning is perhaps the most pervasive and disabling disturbance in patients with advanced kidney disease who are on chronic dialysis," said lead researcher Zoccali.
Adding, "While the effect of regular physical exercise training on physical performance in selected dialysis patients studied in standardized experimental settings in the laboratory is well documented, how exercise training should be articulated and implemented still remains an open problem. Our study shows that simple, home-based exercise programs hold potential for improving physical functioning in dialysis patients.
