Mapping knee skin surface sensitivity and temperature following cryotherapy
Keywords:cryotherapy; cooling; knee; thermal imaging; skin sensation
To investigate the effects of cryotherapy on knee skin surface sensitivity and temperature using monofilaments and thermal imaging.
Following a 20-minute cryotherapy exposure (crushed ice), knee skin surface sensitivity and temperature was mapped in 19 healthy participants using infrared camera and tactile sensory evaluation. The data were collected before and up to 20 minutes after cryotherapy exposure.
Comparing to baseline, in women, significant decrease in skin surface sensitivity in the upper medial section of photographic knee pain map was observed up to 20-minutes after cryotherapy exposure. In men, the respective difference was observed only immediately after the explosion.
Crushed ice application may reduce skin surface sensitivity around a knee medial aspect and result in impeding return to play due to affected joint position sense following cryotherapy.
