The characteristics of standing centroid oscillation by the presence or absence of equinus in ambulant patients with cerebral palsy

Abstract

【Purpose】 This study aimed to investigate the characteristics of standing centroid oscillation by the presence or absence of equinus in ambulant patients with cerebral palsy. 【Methods】 Nineteen patients whose gross motor functions were classified as level I or II were selected (non-equinus group, 8 patients; equinus group, 11 patients). We examined the standing centroid oscillation by eye-opening and eye-closing. We analyzed the data by performing a repeated-measures two-way layout analysis of variance, and multiple comparisons using the Bonferroni method that assumed centroid oscillation as a dependent variable. 【Results】 The total length of body sway had main effect the presence or absence of equinus and both eye-opening and eye-closing, and interaction was confirmed. In the eye-closing, the total length of body sway significantly decreased in the equinus group compared with that in the non-equinus group. 【Conclusions】 Our results suggest that standing centroid oscillation changed according to the equinus group or the non-equinus group. In the equinus group, we concerned important to do preventive intervention for secondary disability because each joints were rocked with standing.
