Therabody's RecoveryTherm Hot and Cold Vibration Knee improves rehabilitation and recovery time, enhances range of motion, lessens tensions and aches, reduces pain and inflammation and accelerates blood flow and pain relief. Three built-in treatment programs and vibration modes offer enhanced relief in a one-size-fits-all design. Wrap is made of neoprene and germanium fabric (made of fibers which include, among other things, germanium [a metalloid element] alloy particles) which naturally emits far infrared light to help regulate temperature, increase circulation and enhance the body's natural healing process. Removable battery is compatible with other RecoveryTherm products and will last 60 minutes on cold mode, 90 minutes on hot mode and 30 minutes on contrast mode. RecoveryTherm Hot and Cold Vibration Knee device also includes soft case and USB-C charging cable. Package/UOM: Each (EA); manufacturer item TB03250-01; UPC 810036059732.
