They have been manufactured with a precise combination of materials to give them the perfect hardness that is required of a therapy ball. They are not children's toys or bouncy balls but are intended for physical therapy. They are similar in size to lacrosse balls and can be used for pinched nerve lower back pain, herniated disc pain relief, and pinched nerve neck pain. Great for acupressure point relief, these provide excellent deep tissue massage to relieve pain and provide muscle knot relief to sore and fatigued muscles.
