the keyhole approach to cryotherapy

Thermal imaging pictures comparing a large area cooling device to ProMOTION EV1 tell us an interesting story: Just because it feels cold, doesn’t mean it is cooling effectively!

ProMOTION EV1 can accurately control and maintain the desired temperature between 6-40 °C for the full therapy program and only targets the affected area. Our thermal imaging camera shows skin temperature taken after completing a 10-minute cryotherapy program with 75 mmHg compression, at 6 °C, comparing ProMOTION EV1 to a large area cooling device.



Achieve the Same Pain Relief as Large Area Cooling
Research has shown that targeted cryotherapy can achieve the same pain relief as traditional cryotherapy modalities covering a larger area. 

Without Impacting Muscle Strength & Stability
Cooling a large area has been shown to reduce muscle strength and stability, which risks re-injury when returning to load bearing. (1)

Allows Early Activity to Speed Up Recovery and Get Back to Fitness Faster
Using targeted therapy can reduce the effects on strength and stability and support individuals to return to rehabilitation exercises earlier, at a lower risk of re-injury. (2-6)
