John Rich, ATC
Decreased Spasm and edema formation
Decreased Pain sensation
Lasting effects of cold play a role in the healing process
An optimal environment for healing
An essential component to the initial treatment of acute injuries
Limited research to examine the role of elevation in vascular and temperature changes during cryotherapy
A valid and reliable tool for measuring tissue temperature
Tracks dynamic changes in tissue temperature
Ideal tool for monitoring recovery of tissue temperature
The physiological changes following cryotherapy can be measured and can remain consistent
Compare the physiological effects of ice with elevation, and ice with a sub-maximal movement (walking), and how elevation alone will effect the healing process.
To determine the cooling effects of skin temperature and the peripheral blood flow at the lateral ankle joint.
The “wrap and go” technique will provide the therapeutic effects necessary for healing.
The RICE method will produce more beneficial therapeutic effects that will last longer after the ice is removed, allowing for more decreased inflammation and healing time.
Heavy duty ice bags (9 ½” x 18”)
