Effect of Hop-Stabilization Training on Ankle Instability and Function of Adolescent Female Basketball Players with Chronic Ankle Instability: A Double-Blind, Prospective, Cluster-Randomized Controlled Trial.

研究概要

Thirty-two adolescent female basketball players with chronic ankle instability were cluster-randomized to hop-stabilization training (n=16) or traditional balance training (n=16). The primary outcome was self-reported ankle stability (Cumberland Ankle Instability Tool, CAIT) and sport-specific performance (T-test, lateral hop, figure-8 hop). Secondary outcomes included static balance (center-of-pressure ellipse area and velocity), dynamic balance (Star Excursion Balance Test), and isometric ankle strength (dorsiflexion, plantarflexion, inversion, eversion). Outcomes were assessed at baseline and after 6 weeks (3×/week, 20-min sessions). Overall, the results showed both groups improved CAIT and balance, but hop training produced greater gains in agility/hopping tests and larger increases in dorsiflexion and eversion strength. These findings suggest sport-specific hop training more effectively targets neuromuscular deficits relevant to basketball than conventional balance work.
