Postural analysis of children with muscle retraction after six-month exercise or heel cup interventions in a randomized trial.

研究概要

One hundred fifty children with triceps surae retraction were randomized to stretching exercises (n=76) or 5 mm EVA heel cups (n=74). The primary outcome of interest was postural control quantified as elliptical area of oscillation (cm²) with the Gyko system across eyes-open/closed on firm and foam surfaces; models adjusted for sex, age, and physical activity. Secondary variables included ankle dorsiflexion (lunge test) and physical activity level. Outcomes were assessed at baseline, 3 months, and 6 months. Overall, the results revealed stretching produced progressive reductions in sway by 6 months, whereas heel cups increased sway. Consequently, a simple daily stretching routine improved postural control, while heel cups worsened it over six months.
