Purpose:
The effects of abducted standing on hip migration percentage (MP) and range of hip and knee motion in children with cerebral palsy were studied for more than 7 years in 2 case-control groups. One group had adductor-psoas tenotomy and the other did not.
Methods:
Case participants performed 15° to 30° of abduction per hip. Controls performed 0° to 10° of abduction and were matched on age, surgery, and follow-up time.
Results:
Median MP decreased 7.0% in the participants without surgery, increased 6.5% in their matched participant, and decreased 3.5% in the participants who had adductor-psoas tenotomy. Migration percentage decreased 18% in participants who after surgery performed abducted standing. Range of motion was greater after surgery in participants who performed standing abduction.
Conclusions:
Standing abduction at 15° to 30° for 10 h/wk reduces MP and preserves range of motion for up to 7 years. This is a new contribution to research for children with cerebral palsy.
