Plain English summary of protocol

Background and study aims:
The use of cryotherapy (cooling therapy) in the form of ice packs, gel packs, and ice immersion are frequently used to treat minor muscle injuries. Although ice is known to be effective in decreasing pain and feeling, its effect on balance has received comparatively little attention. In addition to the various benefits of cryotherapy, reduced performance scores have been reported immediately after treatment. The role of quadriceps (thigh) and hamstring (calf) muscles for maintaining standing balance is well established, but the effect of cooling of these muscles on standing balance has not been reported previously. The aim of this study therefore is to compare the effect cooling the quadriceps and hamstring muscles on standing balance in healthy men.

Who can participate?
Healthy men aged between 20 and 30.

What does the study involve?
Participants are randomly allocated to one of three groups. Those in the first group are asked to lie down on their back and have a cool pack placed on their thigh for 20 minutes. Those in the second group are asked to lie down on their front and have a cool pack placed on their calf for 20 minutes. Those in the third group rest for 20 minutes and do not receive any cooling. At the start of the study and after the cooling period (20 minutes), participants in all groups stand on a special plate which measures their balance.

What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating.

InterventionParticipants are randomised to one of three groups by lottery method.

Quadriceps cooling (QC) group: Participants are asked to lie down in a supine position and a cold pack (gel pack, temperature -60 C to -120 C) is placed on the anterior thigh (from apex of patella to mid-thigh) of the both limbs for 20 minutes.

Hamstrings cooling (HC) group: Participants are asked to lie down in a prone position and a cold pack (gel pack, temperature -60 C to -120 C) is placed on the posterior thigh (from base of the popliteal fossa to mid-thigh) of the both limbs for 20 minutes.

Control (no cooling) group: Participants rest without any intervention.

At baseline and post-cooling/rest (20 minutes) participants have their sway velocity assessed using a force plate.
