Effect of Stretching vs Heel Cups on Postural Control in Children with Triceps Surae Retraction
Postural analysis of children with muscle retraction after six-month exercise or heel cup interventions in a randomized trial.
Sci Rep. 2025 Apr 19;15:13578.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.
