At first glance, Gua sha treatment looks like it would be painful, but it is actually healing. This traditional East Asian treatment sometimes results in red splotchy marks on the skin that look like scrapes or light bruising, but in actuality it is a vascular response called transitory therapeutic petechiae.
The technique, which is offered by ATI’s physical therapists in the Chattanooga region, involves continuous scraping of the skin to intentionally improve blood flow and reduce swelling. According to Andrew Marini, DPT, MS, ATC, Regional Director, ATI Physical Therapy in Chattanooga, TN, modern research has shown that Gua sha has a therapeutic effect.
“The continuous rubbing on the skin pushes blood through the capillaries, causing a histamine response and more blood flow and oxygen to the tissues. Anytime you can increase blood flow, you increase healing,” said Marini.
Marini explains it works better for some diagnoses than hands-on therapy alone because you can concentrate the pressure.
“The surface area of my finger doesn’t allow for high level of pressure in a small area the same way that Gua sha does,” said Marini.
The increased blood flow causes the small red dots, called petechiae, which usually fade within two to three days after treatment. And while the scraping can cause a little discomfort, Marini says the more persistent muscle or tissue pain improves.
“Some people really love it. It can hurt a little, but the overall impact is positive,” said Marini.
Marini specializes in the treatment of the foot and ankle and has found the technique to be a good treatment for the Achilles tendon, or bruises in the calf or shin.
“Gua sha reduces swelling and pain. By dispersing the swelling so that it doesn’t accumulate in one area, it takes pressure off of the nerves, decreases lactic acid and has a desensitizing effect to reduce pain, resolve spasms, and improve mobility,” said Marini.
Other diagnoses that may benefit from Gua sha include:
- Plantar Fasciitis
- Lateral/Medial Epicondylitis
- DeQuervain’s
- Trigger Finger
- Frozen Shoulder
- Scarring
- Iliotibial (IT) Band Syndrome
- Hamstring Strains
- Achilles Tendinopathy
