Context
The combined effects of strength and proprioception training, especially in individuals with ankle instability, have not been studied extensively.
Objective
To examine the influence of 6 weeks of strength and proprioception training on measures of muscle fatigue and static balance in those with unilateral functional ankle instability (FAI).
Design
Pretest–posttest, randomized groups.
Setting
A climate-controlled sports-medicine research laboratory.
Subjects
38 subjects with self-reported unilateral FAI.
Measurements
Muscle fatigue was determined using the median power frequency ( f med ) from an electromyographic signal, and static balance was assessed using center-of-pressure values obtained from a triaxial force plate.
Results
There were no significant effects of the strength or proprioception training on our measures of muscle fatigue and static balance.
Conclusions
Strength training, proprioception training, and the combination of the 2 failed to improve postural-stability characteristics in a group of subjects with FAI.
