The effect of torsional shoe flexibility on gait and stability in children learning to walk.

Purpose: To examine the effects of different torsional flexibilities of shoes on gait and stability in children who are newly walking.

Methods: Twenty-five children walking 5 months or less were evaluated barefoot and in 4 shoes with different torsional flexibilities (UltraFlex, MidFlex, LowFlex, and Stiff). Gait pattern was assessed using GaitMatII.

The functional effect of a distal rectus femoris tenotomy in adults with cerebral palsy.

The purpose of this study was to determine the effect of a distal rectus femoris tenotomy on function and gait in adults with cerebral palsy who had diminished knee flexion during swing. A stiff knee gait pattern is commonly seen in individuals with cerebral palsy and frequently leads to tripping and falling. Five subjects, 25-51 years, (34.

Effect of shoe flexibility on plantar loading in children learning to walk.

Background: In a previous pilot study of "cruisers" (nonindependent ambulation), "early walkers" (independent ambulation for 0-5 months), and "experienced walkers" (independent ambulation for 6-12 months), developmental age significantly affected the children's stability when walking and performing functional activities. We sought to examine how shoe structural characteristics affect plantar pressure distribution in early walkers.

Methods: Torsional flexibility was evaluated in four shoe designs (UltraFlex, MedFlex, LowFlex, and Stiff based on decreasing relative flexibility) with a structural testing machine.
