RESUMEN
Objective To evaluate the effect of weight-bearing alignment training (WBAT) in correcting anterior pelvic tilt in children with cerebral palsy.Methods Twenty-seven children with cerebral palsy and anterior pelvic tilt were recruited and randonly assigned to a WBAT group,a strengthening group and a standing group,each of 9.In addition to routine medication and rehabilitation training,the 3 groups received WBAT,strengthening training or standing training respectively for 20 minutes a day,5 times a week for 4 weeks.Before and immediately after the treatment,the subjects' anterior superior iliac spine-posterior superior iliac spine angles (ASIS-PSIS angles) were assessed along with their anterior-posterior angles (A-P angles) and distances in a 1-minute walk test.Results The WBAT group showed significant improvement in their average ASIS-PSIS angle (to 18.61 ± 3.13°),A-P angle (to 23.31±3.81°) and the distance in the 1-minute walk test after the treatment.The standing group had significant progress in improving their A-P angles (to 24.48±4.33°),and the strengthening group had significant improvement in the distance walked in the 1-minute walk test.The average improvements in the ASIS-PSIS angle and walk distance in the WBAT group were significantly better than in the other 2 groups.Conclusion WBAT is superior to strengthening and standing training in improving the ASIS-PSIS angle,A-P angle and walking ability of children with cerebral palsy and anterior pelvic tilt.
