PURPOSE: The purpose of this study was to investigate the effects of biofeedback exercise training on muscle activity and activities of daily livings (ADL) in hemiplegic patients. An experimental group consisting of 17 people, was given biofeedback exercise training for 30- 60 minutes per week for 5 weeks, while a control group consisting of 18 people, was given normal exercise with quasi-experimental design. RESULT: The results of the study show that biofeedback exercise is effective for improving muscle activity in hemiplegic patients, especially in the hemiplegic limbs. However, this study found no significant differences in ADL and IADL between the experimental and the control groups. It implies that ADL and IADL may not be improved for a short period of time, such as 5 weeks, for people with more than five years of hemiplegia. The study suggests that the effect of biofeedback exercise on ADL and IADL should be determined in hemiplegic patients in acute stage.
The purpose of this study was to investigate the effects of constraint-induced (CI) movement using self-efficacy on U/E function of chronic hemiplegic patients. CI movement discourages the use of the unaffected U/E, combined with intensive training of the affected U/E.
A non-equivalent pretest-posttest design was used. Study subjects were 40 hemiplegic patients conveniently selected from 2 different community health centers. The experimental subjects participated in the CI movement program for 6 hours daily over a period of two weeks. The exercises for affected U/E consisted of warming up, main exercise and ADL practice. To encourage the participants' behaviors self-efficacy enhancing strategies were used, which included performance accomplishment, vicarious experience, verbal persuasion and emotional arousal.
After 2 weeks of treatment, the grip power, pinch power, wrist flexion/extension, elbow flexion, and shoulder flexion/extension were significantly higher in the experimental subjects than in the control subjects. However, there was no significant difference in hand functions of the two groups.
The above results show that the constraint-induced movement using self-efficacy could be an effective nursing intervention for improving U/E function of chronic hemiplegic patients. Long term studies are needed to determine the lasting effects of constraint-induced movement.
The purpose of this study was to identify the mediating effect of depression in the relationship between muscle strength of extremities and falls among community-dwelling elderly.
Two hundred forty-seven participants were recruited from a public health center, a hall for the aged and a school for the aged in B city. Face-to-face interviews were conducted using questionnaires from May to September of 2007. Data was analyzed with descriptive statistics, Pearson correlation, and multiple regression using the SPSS WIN 14.0 program.
There was a significantly negative relationship between muscle strength of lower extremities and falls, muscle strength of left upper extremity and falls, and muscle strength of right upper extremity and falls. Depression positively correlated with falls. Depression showed mediating effects between muscle strength of extremities and falls. Weakness of muscle strength of extremities increased depression and the increased depression increased the frequencies of falls.
For the effective management and prevention of community-dwelling older adults’ falls, exercise programs including depression-decreasing strategies should be established. These exercise programs can decrease depression which is the mediator role between the degrees of muscle strength of extremities and falls.
