An interventional study of Cryotherapy and Control in Musculoskeletal Injury, sponsored by University of Calgary. Completed at 1 site in Canada. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2014-04-16.

The purpose of this study is to determine the immediate effects of cryotherapy on the lower extremity biomechanics during running.
Cryotherapy or cold therapy has widely been used as a treatment modality in both acute and chronic injuries. It is believe that the application of cryotherapy can help to decrease pain, muscle soreness, soft tissue swelling, and cause vasoconstriction of blood vessels reducing heat loss. The nerve conduction velocity and muscle-spindle firing rate also decreases with cryotherapy, which results in changes in proprioception acuity. Cryotherapy has also been used prior to exercise (pre-cooling) to improve endurance activities. However, given the possible detrimental effects of cryotherapy on proprioception acuity, the use of this treatment modality prior to exercise could pose an increased risk of musculoskeletal injury. The effects of cryotherapy on lower extremity biomechanics during athletic movements is poorly understood despite the wide use among physiotherapists, athletic therapists and clinicians. Therefore, the purpose of this investigation is to determine the effects of cold water immersion on lower extremity biomechanics during running. The investigators hypothesize that cryotherapy as a form of treatment can increase the load in the lower extremity joint during gait biomechanics.

Exclusion Criteria:
The subjects will be exposed to a cold (\~ 12° C) water immersion tub at the umbilical level for 20 minutes.
Other: Cryotherapy
The subjects will be exposed to a non-cold (\~ 26° C) water immersion tub at the umbilical level for 20 minutes.
Other: Control
The subjects will be exposed to a cold (\~ 12° C) water immersion tub at the umbilical level for 20 minutes.
The subjects will be exposed to a non-cold (\~ 26° C) water immersion tub at the umbilical level for 20 minutes.
Knee frontal plane moments
Knee frontal plane loading will be calculated using inverse dynamics based on the ground reaction force data from a force plate and with kinematic data recorded by high speed cameras. Kinematics and kinetics data will be taken during running at 4m/s from each participant prior and after the intervention.
Time frame: 20 minutes
