dc.description.abstractInjury statistics report that 45% of all athletic injuries are ankle sprains, with 85% of those occurring at the lateral aspect of the ankle. Cryokinetics is a rehabilitation technique that uses cooling with the goal to decrease neural inhibition, thus allowing for greater pain-free range of motion. The present study evaluated how cryokinetics affected sensory perception, range of motion (ROM) and postural stability with previously injured (asymptomatic) versus uninjured ankles. Tactile sensation at the lateral ankle, dorsiflexion at the ankle, as well as postural stability (with eyes open and closed) before and after a cryokinetic protocol were evaluated. The results demonstrate how cryokinetics effects sensory perception, ROM and postural stability in relation to injury history. Two-point discrimination testing demonstrated a significant reduction in tactile acuity after cryokinetics. Functional range of motion testing demonstrated an interaction between a history of ankle injury compared to no injury history, where functional ROM was significantly greater after cryokinetics for previously injured ankles. Overall, vision had the largest impact on postural stability. However, there was an interaction across previous injury history, intervention and vision for median frequency of medial/lateral-Center of Pressure. The current results highlight that ankle injury history is a significant variable when assessing the affects of cryokinetics on functional ROM of ankles and that vision affects postural stability more than cryokinetics. Future research could investigate the effects of cryokinetics on acute care injury management of ankle sprains, and perhaps to ligamentous or soft tissue injuries at joints other than the ankle.en_US
