Shock Blocker™ was developed for TendonEaseSM by Dr. Mark Greenberg, a renowned Sports Medicine Specialist – and former Tennis Elbow sufferer – who has treated pro and amateur athletes for 20+ years. He discovered that by targeting the cause of Tennis/Golfer's Elbow, a specially designed and constructed finger ring could absorb the damaging shock created by impact in the hand and reduce the vibration that triggers pain in affected tendons.
