Effects of Reformer Pilates and Vestibular Exercise Programs on Balance and Gait in Children With Visual Impairment
31 août 2026 mis à jour par: Marmara University
Effects of Different Exercise Programs on Balance Performance and Gait Biomechanics in Children With Visual Impairment
This study looks at whether Reformer Pilates can help children and adolescents with visual impairment improve their balance, walking patterns, and muscle strength.
Participants are between 10 and 17 years old. They are randomly placed into one of two groups: an exercise group or a control group.
Those in the exercise group take part in 12 supervised Reformer Pilates sessions over 6 weeks, meeting twice a week. Those in the control group keep up with their usual daily activities and do not join the exercise program during this time.
Before and after the 6-week period, researchers measure each participant's balance, walking patterns, and muscle strength. They then compare how much each group changed.

Muscle Strength: Isometric Knee Extensor Muscle Strength
Délai: Baseline and post-intervention at Week 6
|
Knee Extension Isometric Strength Assessment: Participants will sit with knees at ~90° flexion, feet unsupported, distal posterior thigh positioned ~10 cm from the chair's front edge, arms on the armrests with hands gripping the handles, and thighs/pelvis stabilized with a strap.
A dynamometer will be fixed to an apparatus mounted behind the chair using a rigid, non-stretch strap positioned ~2 cm proximal to the lateral malleolus and secured across the anterior tibial surface; participants will perform knee extension, applying maximal isometric force against the dynamometer through the strap.
Three 5-second maximal contractions will be performed, with 1-minute rest between trials and verbal encouragement to ensure maximal effort; peak force will be recorded for each trial.
