Cryotherapy does not affect peroneal reaction following sudden inversion . CONTEXT If ankle joint cryotherapy impairs the ability of the ankle musculature to counteract potentially injurious forces , the ankle is left vulnerable to injury . OBJECTIVE To compare peroneal reaction to sudden inversion following ankle joint cryotherapy . DESIGN Repeated measures design with independent variables , treatment ( cryotherapy and control ) , and time ( baseline , immediately post treatment , 15 minutes post treatment , and 30 minutes post treatment ) . SETTING University research laboratory . PATIENTS OR OTHER PARTICIPANTS Twenty-seven healthy volunteers . INTERVENTION ( S ) An ice bag was secured to the lateral ankle joint for 20 minutes . MAIN OUTCOME MEASURES The onset and average root mean square amplitude of EMG activity in the peroneal muscles was calculated following the release of a trap door mechanism causing inversion . RESULTS There was no statistically significant change from baseline for peroneal reaction time or average peroneal muscle activity at any post treatment time . CONCLUSIONS Cryotherapy does not affect peroneal muscle reaction following sudden inversion perturbation .
