Therapeutic exercise putty also provides benefits like increased blood flow for healing, optimizing functional hand range of motion, improving fine motor skills, and even stress relief. For gently increasing range of motion or to reduce stiffness, use the softer putty. For developing a stronger grip, use firmer putty. Each color-coded putty is a different consistency ranging from extra soft yellow to firm blue for a variety of hand and finger exercises. CanDo Theraputty is non-toxic, non-oily, bleed-proof, latex-free, and leaves no residue. The putty will not fragment, separate, stain, or stick to the skin. Users will find squeezing, stretching, twisting, pinching, pulling the therapy in different ways will meet a wide range of strengthening needs. Theraputty can be formed into various shapes, included in the manual, providing a balanced exercise program. Strengthening opposing muscles in the hand requires a delicate muscular balance. We recommend supervision by your therapist or doctor regarding repetitions and intensity of use and notification in case pain is experienced. To care for Theraputty, avoid the use of lotion and wash hands before use to prevent soiling and to help maintain the resistance of the putty. Theraputty should be kept in the storage container when not being used. It should not be placed on rugs or fabrics for a prolonged period of time.
