Cupping is a popular soft tissue modality used in physical therapy that involves placing specialized cups on the skin to create suction, which helps mobilize blood flow and promote healing in targeted areas. This technique works by lifting the skin and fascia, encouraging improved circulation, reducing muscle tension, and alleviating pain. 

Patients often report a sense of relaxation and relief from tightness following cupping sessions, as well as enhanced recovery from injuries. Additionally, the increased blood flow can aid in the removal of metabolic waste, further supporting overall tissue health. Cupping is typically used in conjunction with other therapeutic modalities to maximize its benefits.
