Abstract

|
In an attempt to investigate the effect of exercise on pain, helplessness, and perceived benefits of exercise of patients with knee osteoarthritis, a pre-experiment, one group pretest & post-test design, was planned.
Exercise was carried out from May through July, 1995 at isokinetic exercise room in rehabilitation department of University Hospital in Taejon and patients home. The subjects were twelve female clients conveniently sampled from University Hospital located in Taejon, between 39 and 61 years of age, who had a osteoarthritis in knee. 10 subjects completed 6 weeks exercise program.
In this study, exercise was composed of three sessions per week for 6 weeks, one isokinetic exercise session at angular velocity of 60° and 180° with Cybex isokinetic dynamometer and two resistance home exercise sessions with elastic band. In one session, patients exercised about 30?40 minutes.
Data were analyzed with mean, percentage of change, and Wilcoxon signed rank test using SAS program.
Results were obtained as follows
1) Pain was decreased after 6 weeks exercise than that of before experiment, but there was no statistically significant difference(SR=12, P=0.1172).
2) Helplessness was decreased after 6 weeks exercise than that of before experiment, and it was a statistically significant difference(SR=26, P=0.0059).
3) Perceived benefits of exercise was increased after 6 weeks´ exercise than that of before exercise. But, there was no statistically significant difference(SR=-7.5, p=0.0625).
This study was a pre-experiment with small size subjects. So, controlled experimental study is necessary to determine the effect of exercise program on pain, helplessness, and perceived benefits of exercise of patients with knee osteoarthritis.
