Einzelfallserie zum gezielten Stabilitätstraining des Vorfußes und Rückfußes bei Fußballern mit chronischer Instabilität des Sprunggelenks

Abstract

BackgroundThe forefoot and rearfoot may individually contribute to the development of chronic ankle instability after an ankle sprain. PurposeTo explore the impact of a training program to increase forefoot and rearfoot stability on clinical outcome measures in three football players with chronic ankle instability. MethodsTwo players began with single-leg stance exercises to improve stabilization of the forefoot for three weeks, whereas one player completed exercises to improve stabilization of the rearfoot. Then, the players changed the conditions for another three weeks. ResultsSlight improvements for the Cumberland Ankle Instability Tool (CAIT) and the Foot and Ankle Outcome Score were observed in all players after six weeks. The CAIT-score of the player who started with the exercise to improve stabilization of the rearfoot improved after three weeks. The Y-Balance- composite score only increased in both players who began with the exercises to improve stabilization of the forefoot after three and six weeks. ConclusionTargeted rearfoot training seems to lead to a slight reduction of the severity of instability and disability. Targeted training of the forefoot may primarily address dynamic balance.
