Studies have indicated that muscle strengthening can increase muscle strength; however, the effectiveness of strengthening for motor function is still controversial. The movement pattern of isolated and open kinetic chain under traditional strengthening program does not similar to the functional movement used in activity of daily living. A functional sitto- stand loading testing (STSLT) and exercise (STSLE) method was developed in our laboratory before. That STSLT method is a multi-joint, closed kinetic chain activity with strength and movement control dimensions. Our previous study found that STSLT was a reliable test for children with CP and non-disabled children. The purpose of this study was to investigate the relations between (1) functional strength and gross motor; and (2) STSN1RM and the individual muscle strength in children with CP. Methods: A convenience sample of 20 children with spastic diplegia in Northern Taiwan was recruited. Their age ranged from 892314B002454.doc2001/10/29 72 – 122 months (88 ± 14 mo). Gross Motor Function Measure (GMFM), normalized 1 repetitive maximum of STSLT (STSN1RM), speed of sit-to-stand 5 times and maximum isometric contraction in lower extremities with Nicholas hand-held dynamometer were measured. STSN1RM represents the functional strength of lower extremities. Results: There was significant correlation between STSN1RM and the scores of 3 dimensions of GMFM (r = 0.76~ 0.80, p <0.01), and between STSN1RM and muscle strength of 12 muscles of lower extremities(r = 0.4~ 0.78, p <0.05). The stepwise regression test found that the muscle strengths of knee extensor and hip abductor were the best predicting factors for STSN1RM ( r2 = 0.72, p <0.01). Conclusion: STSN1RM is highly correlated with the gross motor function and the muscle strength of lower extremities in children with CP. However the effects of STSLE need further studies. |
