“How should I apply this information?”

This study was a case series in which 2 groups of children with cerebral palsy who were nonabmulatory were followed for 1 year to determine the effect of standing with maximal hip abduction and extension from ½ to 1½ hours per day. One group of 3 children who underwent bilateral adductor-iliopsoas-tenotomies was matched with 20 control subjects. Another group of 8 children, the prevention group, received the standing intervention and did not require surgery. This second group was matched with 63 control subjects. Pre- and postintervention radiographs were used to determine migration percentage (MP) and range of motion.

* In the surgery group, those using the stander demonstrated the largest decrease of MP.

* In the prevention group those receiving intervention for 1 hour per day demonstrated a significant improvement in MP.

* In the prevention group, those who stood for shorter periods of time (½ hour per day) maintained the MP or had MP increases less than the control group.

* Contractures were noted only in the involved hip and knee musculature in the control group that did have surgery.

* Families and children reported that manual stretching was easier after standing and that while in the stander they were able to perform other skills, that is, play activities.

* This intervention is relatively easy to carry out in home or school environments by parents/caregivers.

“What should I be mindful about in applying this information?”

* This is a case series with a very small number of subjects in both intervention groups and not a clinical trial.

* Children received other therapeutic interventions during the year; thus, the influence those therapies had on MP and range of motion is difficult to determine.

* This study only investigated the abduction angle of 30°. The authors state that it is yet to be determined if 30° is necessary to keep the acetabular rim free from pressure.

* Clinicians should exercise caution if using the stander for children with hip flexor and knee flexor contractures.

* Care should be taken to not apply the results to populations other than children with cerebral palsy of similar age who are nonambulatory.
