Swanson™ Hand Cone is shaped to fit the anatomy of a partially closed fist. The hook and loop strap keeps the cone in place -- each finger has its own contoured resting place. No injury-causing hard edges. Firm rubber construction has a pleasant tactile feel and does not stimulate finger flexion or spasticity. Developed by Alfred Swanson, M.D., FACS. Fits left or right hand.
