Learning Objective #1: Understand the bone mineral density and physical functioning in hemodialysis patients.
Learning Objective #2: Understand the effects of exercise training in hemodialysis patients.
The purpose of this quasi-experimental study was to explore the effects of an exercise program designed to help hemodialysis patients improve their bone mineral density (BMD) and physical functioning. An intervention study with pre-and-post test design was used. Thirty-seven subjects were recruited from a dialysis centers by purposive sampling and assigned into two groups by their preference: the exercise intervention group (EX) and non-exercise, usual care group (NX). The exercise training was to perform the exercise on dialysis day, 20~30 minutes each session, three sessions per week, persisting 3 months. Nineteen of these patients were assigned to the EX group who received the routine medical care plus exercise training, and 18 were assigned to the NX group who received the routine medical care. The results showed that the mean age was 55.4¡Ó12.7 years. Sixty-eight percent of subjects were male. The mean time on dialysis was 24.6¡Ó22.6 months. The BMD and T-score of femoral neck (FN) and lumbar spine (L1-4) were 0.68¡Ó0.12g/cm2 (T: -1.3¡Ó1.0) and 0.98¡Ó0.17g/cm2 (T: -0.4¡Ó1.4), respectively. The BMD of FN was increased 0.96% in the EX group and decreased 0.01% in the NX group, respectively. It had no statistics significantly, but there was a trend that the more exercise the less bone density loss. After exercise training, the physical functioning was improved significantly in the EX group. The EX group had significantly higher cycles of sit-to-stand in 60 seconds (STS-60) than the NX group. The percentage of improvement in physical functioning in the EX group was higher than those in the NX group. Based upon our findings, we suggest that the change of BMD in 3-month period wasn¡¦t a sensitive indicator, and STS-60 and the distance of 6-minute walk (6MW) will be the sensitive outcome indicators for the physical functioning.
