| ObjectiveTo explore the effects of home aerobic exercises in patients who received maintenance hemodialysis, such as physical function, physical activity, Self-efficacy for exercise, fatigue, physiological and biochemical index, quality of life.MethodsThe research design is a randomized controlled study design. From August2010to June2011,90maintenance hemodialysis patients were recruited in the study and they were assigned into intervention group (n=45) and control group (n=45). The patients in the intervention group received routine care and guidance, plus6months home-based aerobic exercises intervention, while the patients in the control group only received routine care and guidance. Data were collected before the intervention and at the3rd month and6th month after intervention, including the normal walking speed, the maximum walking speed, physiological and biochemical index, physical activity(IPAQ), self-efficacy for exercise, fatigue(RPFS) and quality of life(SF-36). The data were analyzed using the SPSS16.0statistical software.Results1. Repeated-measures ANOVA indicated that the maximum walking speed was different between the intervention group and control group after intervention(F=4.353,P<0.05), but the normal walking speed had no statistical significance. At the ends of the3rd and6th month, the maximum walking speed increased significantly in the intervention group compared with the control group. The normal walking speed between two groups had no statistical significance in3rd month (P>0.05), and had statistical significance in6th month (P<0.05).2. The physical activity level and metabolic equivalents increased significantly in the intervention group compared with pre-intervention and were higher significantly than the control group(χ2=6.041,P<0.05).There was no statistical significance in the control group between before and after intervention (P>0.05).3. The score of self-efficacy for exercise of intervention group was higher significantly than the control group after intervention(F=6.150,P<0.05), and there was the same result over corresponding period.4. Except cognitive/mood dimension, the scores of total fatigue and other dimensions were lower in the intervention group than the control group(P<0.05), and there was the same result over corresponding period.5. Repeated-measures ANOVA indicated there was no statistical significance between two groups on physiological and biochemical index including body mass index, hemoglobin, hematocrit, albumin, serum creatinine, blood urea nitrogen(P>0.05) after intervention. Hematocrit between two groups had statistical significance at the ends of the6th month.6. Repeated-measures ANOVA showed that the scores of physical function, vitality, physical component summary between two groups had statistical significance after intervention. Compared with the control group in corresponding period, the scores of physical function, role physical, vitality, physical component summary increased in the intervention group(P<0.05).ConclusionsThe home-based aerobic exercise is safe and convenient. Compared with the control group, the aerobic intervention could increase physical function, the physical activity level, metabolic equivalents, self-efficacy for exercise and could improved level of fatigue and quality of life. But more researchs are needed to explore the effect of home-based aerobic exercise to physiological and biochemical index. |
