Abstract
|

PURPOSE: This study compared the effects of chest expansion resistance exercise (CERE) and breathing retraining (BRT) on stroke patients’ chest expansion and maximal inspiratory pressure(MIP), thereby intending to present an effective intervention method for enhancing their respiratory functions.
METHODS: The subjects were 30 stroke patients and randomly and equally assigned to a CERE group (10), a BRT group (10), and a control group (10). The intervention was applied to each group five times per week, 30 minutes per each time, for six weeks. A tapeline was used to measure upper and lower chest expansion and MIP prior to and after the intervention and the results were compared.
RESULTS: After the intervention, the upper and lower chest expansion was considerable in the CERE group (p<.01), significant in the BRT group (p<.05) but was not significant in the control group (p>.05). According to the post-hoc test result, the upper and lower chest of the CERE group and the BRT group significantly expanded compared to that of the control group (p<.05) and the upper and lower chest of the CERE group statistically significantly expanded relative to that of the BRT group (p<.05). According to the MIP evaluation result, the CERE group saw considerable improvement (p<.01) and the BRT group underwent significant changes (p<.05), but there were no significant changes in the control group (p>.05). The post-hoc test result was that the CERE group and the BRT group saw significant improvement compared to the control group (p<.05) and the CERE group experienced statistically significant enhancement relative to the BRT group (p<.05).
CONCLUSION: As an intervention for respiratory function improvement, CERE is considered effective for strengthening respiratory muscles and promoting chest expansion through manual resistance by a therapist.
