Brief Summary
Cryotherapy after surgery is widely utilised and has numerous practical applications for post-operative rehabilitation. Previous research has suggested that during cold therapy, the skin temperature of the knee should be reduced to 10-15°C to maximise the therapeutic benefits of cooling while avoiding the risk of cold injuries such as nerve damage and frostbite (Wilke and Weiner, 2003; Bleakley, McDonough and MacAuley, 2004). The temperature range at which a device cryocompression device should be set in order to achieve a skin temperature within the therapeutic range of 10-15°C is unknown. Furthermore, there is evidence to suggest that the temperature of the device does not equal that to which the skin is reduced, plus different devices do not achieve the same reduction in skin temperature despite the ice-water within the knee sleeve being maintained at similar temperatures (Selfe et al., 2009). Therefore, it is not sufficient to assume that the temperature setting of a cryo-compression device reflects the skin temperature achieved. The aim of this study is to determine which temperature of ice-water flowing through a Physiolab S1 cryocompression device is able to reduce skin temperature around the knee to within the previously stated therapeutic range.

Outcome Measures
Primary Outcomes (1)
Skin Temperature
Skin temperature will be measured using a thermocouple positioned 20 mm distal to the patella. This sensor will be attached prior to the cryocompression device being applied, and will remain in place until the testing session is complete and skin temperature is \>15℃. (The therapeutic skin temperature range for cryotherapy is thought to be 10-15℃). Temperature will be measured prior to the cryocompression device being applied; every 5 minutes during the test; and every 5 minutes after a test until the skin temperature reaches \>15℃.
up to 14 days
Study Arms (5)
Control
NO INTERVENTIONParticipants will wear the cryocompression device for 30 mins without any cold or pressure being applied to the lower limb by the cuff.
Condition A
EXPERIMENTALParticipants will wear the cryocompression device for 30 minutes while ice-water at a temperature of 6℃ and a pressure of 25 mmHg is applied to the lower limb by the cuff.
Condition B
EXPERIMENTALParticipants will wear the cryocompression device for 30 minutes while ice-water at a temperature of 8℃ and a pressure of 25 mmHg is applied to the lower limb by the cuff.
Condition C
EXPERIMENTALParticipants will wear the cryocompression device for 30 minutes while ice-water at a temperature of 10℃ and a pressure of 25 mmHg is applied to the lower limb by the cuff.
Condition D
EXPERIMENTALParticipants will wear the cryocompression device for 30 minutes while ice-water at a temperature of 12℃ and a pressure of 25 mmHg is applied to the lower limb by the cuff.
Interventions
A cryocompression device will be attached to the lower limb of participants using a cuff spanning from the mid-thigh to mid-calf. The device will exert a constant pressure of 25 mmHg throughout each test session. The device will pump temperature-controlled cold water through the cuff in order to reduce the skin temperature around the knee (and intra-articular temperature). Depending on the condition, the temperature of the water being pumped through the device will be either 6, 8, 10, or 12℃. Each test session will last for 30 minutes. Participants will take part in all conditions, with at least 24 hours rest in between test sessions. Skin temperature around the knee will be measured prior to the cryocompression device being applied; every 5 minutes during the 30 minute test; and every 5 minutes after the test until skin temperature \>15℃.
Eligibility Criteria
You may qualify if:
- \>18 years of age.
You may not qualify if:
- BMI \>40 kg/m2
- History of nerve damage or sensory deficit in the lower limbs (including frostbite)
- Hypersensitivity to cold, including hives
- Active inflammation or pain of the knee
- History of thrombosis, embolism, or other conditions related to impaired peripheral circulation
