Used by therapists in a wide variety of clinical settings for patients who suffer from muscular pain and discomfort. Thera-Cane makes it possible for patients to self-apply pain-relieving deep compression directly to hard, knotted “trigger points” even in the hardest-to-reach muscles between your shoulder blades. Thera-Cane can provide temporary relief from muscular tension, stiffness, tenderness and soreness.
