Effects of a postoperative strength-training program on the walking ability of children with cerebral palsy: a randomized controlled trial

Abstract

Objective: To investigate the effect of a postoperative strength-training program on the walking of children with cerebral palsy (CP).

Design: Randomized controlled trial.

Setting: Hospital rehabilitation department.

Participants: Thirty-nine children with CP (age range, 6-16 y). After orthopedic surgery, the control group (n=20) followed a conventional physiotherapy (PT) program, and the strength-training group (n=19) followed a strength-training program in addition to the conventional PT. Twenty-nine age-matched healthy children were used as references.

Intervention: A 9-month strength-training program.

Main outcome measures: Spatiotemporal, kinematic, and kinetic parameters during gait analysis were analyzed before (E0) and 1 year after (E1) the surgery. For 22 children, a 2-year postoperative gait analysis (E2) took place as well.

Results: At E1, several kinematic and kinetic parameters improved, although there was no significant difference between the groups. Spatiotemporal parameters showed a worsening at E1 and a recovery to preoperative values at E2.

Conclusions: The examined parameters may be more substantially influenced by factors such as the surgery outcome and the variability of pathologic characteristics than by the strength-training program per se. However, a more significant effect of the strength-training may appear if more intense and short-term training protocols are used, considering factors such as patients' motivations, ages, and postoperative statuses.
