At TheraMove & Diagnostics, we use only the DRY CUPPING using either glass cups or silicone cups. Your therapist with place the appropriately sized cups on the area of tightness, either on your back, calves, thighs, hands, etc., using a rubber pump which will create a suction and blood pooling in that area. The cup stays on for 3-5 minutes and maybe moved over the length of muscle for greater benefits.
