TheraBand® Hand Exerciser has a unique soft feel that enables users to complete a variety of movements to strengthen grip, increase dexterity and mobility, and improve fine and gross motor skills through a system of progressive compression while offering the added benefit of hot and cold therapy. The softer red model fills the gap between putty and spring devices and it is not as messy as putty. Recommended for arthritis, repetitive stress injury, stress reduction, stroke recovery and general strengthening.
