Brief Summary:
The purpose of this study is to determine the immediate effects of cryotherapy on the lower extremity biomechanics during running.

Condition or disease Intervention/treatment Phase
Musculoskeletal Injury Other: Cryotherapy Other: Control Not Applicable

Detailed Description:
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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 26 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Basic Science
Official Title: Effects of Cryotherapy on Lower Extremity Joint Biomechanics During Running in Healthy Adults
Study Start Date : November 2012
Actual Primary Completion Date : December 2012
Actual Study Completion Date : January 2013

Arm Intervention/treatment
Experimental: Cryotherapy
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 cold (~ 12° C) water immersion tub at the umbilical level for 20 minutes.

Placebo Comparator: Control
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 non-cold (~ 26° C) water immersion tub at the umbilical level for 20 minutes.




Primary Outcome Measures :
  1. Knee frontal plane moments [ Time Frame: 20 minutes ]
    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.
