Immediate Effect of Postural Insoles on Gait Performance of Children with Cerebral Palsy: Preliminary Randomized Controlled Double-blind Clinical Trial.

[Purpose] Improved gait efficiency is one of the goals of therapy for children with cerebral palsy (CP). Postural insoles can allow more efficient gait by improving biomechanical alignment. The aim of the present study was to assess the effect of postural insoles on gait performance of children with CP classified as levels I or II of the Gross Motor Function Classification System (GMFCS). [Subjects and Methods] the study was a randomized controlled double-blind clinical trial. After meeting the legal aspects and the eligibility criteria, 10 children between four and 12 years old were randomly divided into a two groups: a control group (n=5), and an experimental group (n=5). Children in the control group used a placebo insoles, and children in the experimental group used postural insoles. Evaluation consisted of three-dimensional gait analysis under three conditions: barefoot, shoes without insoles and shoes with postural insoles or shoes with placebo insoles. [Results] Regarding the immediate effects of insole use, significant improvements in gait velocity and cadence were observed in the experimental group in comparison to the control group. [Conclusion] The use of postural insoles led to improvements in gait velocity and cadence of the children with cerebral palsy classified as levels I or II of the GMFCS.

Effect of different insoles on postural balance: a systematic review.

[Purpose] The aim of the present study was to perform a systematic review of the literature on the effect of different insoles on postural balance. [Subjects and Methods] A systematic review was conducted of four databases. The papers retrieved were evaluated based on the following inclusion criteria: 1) design: controlled clinical trial; 2) intervention: insole; 3) outcome: change in static postural balance; and 4) year of publication: 2005 to 2012. [Results] Twelve controlled trials were found comparing the effects of different insoles on postural balance. The papers had methodological quality scores of 3 or 4 on the PEDro scale. [Conclusion] Insoles have benefits that favor better postural balance and control.
