An innovative 3-in-1 hand therapy and rehabilitation system used to increase range of motion, flexibility and grip strength. Performance Grip's resistance level can be adjusted from light to firm allowing this one product to do the job of three. Available unscented, or in five aromatherapy scents from calming Lavender to stimulating Eucalyptus, it will not stain clothing, carpet, or fabric, and is latex-free. Ideal for post surgical exercise to increase mobility and flexibility while building finger/grip strength. And, when resistance level is adjusted, it offers the added benefit of heat or cold therapy.
