| Summary: | Background
Motor impairments caused by stroke result in impaired diaphragmatic and respiratory muscle function, changes in thoracic biomechanics on the hemiparetic side ultimately resulting in decreased efficiency of lung ventilation. This study aimed to examine the efficacy of chest expansion resistance exercise (CERE) on respiratory function, trunk control ability, and balance in patients with chronic stoke. Following a purposive sampling, thirty-five patients with chronic stroke were randomly allocated into two groups, i.e., the experimental group receiving CERE with conventional therapy and the control group receiving conventional therapy alone. Both the groups received therapy four times per week for a period of four weeks (total 16 sessions). Following assessments were done before and after treatment in both the groups: chest expansion ( axillary, nipple, xiphisternal levels) using measure tape, respiratory muscle strength using micro-respiratory pressure meter, trunk control using the Trunk Impairment Scale, and balance using mini-Balance Evaluation Systems Test.
Results
Both groups had 17 participants each (
n
= 34, drop-outs = 1) consisting of 12 males and 5 females having a mean age of 56.5 ± 12.98 years and 59.7 ± 10.2 years, respectively. Intra-group analysis showed a statistically significant increase in mean values of chest expansion, respiratory muscle strength, trunk control ability, and balance in the experimental group whereas the control group showed improvement only in trunk control ability and balance. Inter-group comparison revealed a better improvement in all the outcome variables in experimental group compared to the control group.
Conclusions
Based on these results, this study proved that CERE was more effective in improving respiratory function, trunk control, and balance in patients with chronic stroke. |
