Abstract
This study aims to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and muscle tone, targeting the children with spastic diplegic cerebral palsy. 16 children with spastic diplegic cerebral palsy in IV phase of GMFCS were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, only trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. The trunk muscle strengthening exercise consisted of 2 exercises to strengthen abdominal muscles and back muscles. BPM(Balance Performance Monitor) was used to measure balance performance and MMAS(Modified Modified Ashworth Scale) was used to measure muscle tone. As a result, the changes of sitting balance performance in experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05), the comparison of changes in sitting balance performance in between experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05). Knee flexor muscles and hip adductor muscles in both groups show no significant difference in changes of the muscle tone(p>.05). Therefore, the balance performance in both experimental groups and control groups was improved. However, the experimental group had more significant improvement in balance performance and no change in muscle tone was detected in both groups. Thus, these findings show trunk muscle strengthening exercises are effective in improving the balance performance of sitting posture for the children with spastic diplegic cerebral palsy without changing muscle tone.
