Wearing the Epitact Flexible Thumb Brace (Left Hand) proprioceptive orthotic on a daily basis helps to relieve the joint pain caused by osteoarthritis at the base of the thumb. It restricts traumatic micro-movements (e.g. moving hands in mid-air while walking or talking etc.), holds the thumb in a resting position, and retains heat locally to the joint. It is flexible, thin, and discreet - this orthotic helps you to retain the full functionality of your hand. It can be worn during the day, as often as you like. It has a lifespan of several months.
