Gua Sha: The Ancient Treatment That Paved The Way for Physical Therapists

Gua sha (pronounced gwahshah) is an ancient healing technique that originates from traditional East Asian Medicine practices. Gua sha is also called Instrument Assisted Soft Tissue Mobilization, or simply IASTM. Traditionally, Gua sha was used to move energy throughout the body. Contemporary IASTM is primarily focused on the treatment of musculoskeletal injuries and conditions. However, there is crossover between the two practices and the names are often used interchangeably.  

What is Gua Sha?

Gua sha involves scraping the skin to stimulate blood circulation to the soft tissues. Typically, the practitioner will apply a massage oil to the skin, then scrape the affected area repeatedly, using a downward motion. Gua sha is generally performed on the back, neck, arms, legs, and buttocks; however, some providers may also scrape the feet, hands, or use mild pressure on the face. 

Gua sha can cause light bruising as tiny blood vessels, called capillaries, near the surface of the skin burst. These bruises usually disappear within a few days of the treatment. Gua sha bruises are a form of microtrauma, which create a response in the body that assists in breaking down scar tissue and fibrosis, a condition in which there is a buildup of too much connective tissue formed around an injury.

How Does Gua Sha Work in the Body?

What are the Benefits of Gua Sha Treatments?

What to Expect Before Your First Treatment

Your provider might not manipulate where you think they should. Like many conditions involving nerves, muscles, and bones, the pain is not always in the same location as the injury. Pain radiates and moves through the body and oftentimes the greatest amount of pain is in a different location than the injured area, such as a trigger point or the insertion point of a muscle. A professional trained in Gua sha methods will be able to locate the proper area of treatment based on your condition and injury. 

Like getting a tissue massage, you can expect to feel pressure during the treatment as your practitioner uses the tool on your skin; however, you should not be in pain during the treatment. A professionally trained Gua sha practitioner will be able to use the right pressure for your specific condition and treatment plan. You should communicate with your provider if you feel pain or if the pressure becomes too intense so they can modify the level of pressure being used. 

Some patients need a few treatments with mild or moderate pressure before they are ready for the full pressure needed for effective healing. Some patients report also feeling sore immediately after treatment, but this is typically minimal and not enough to require pain medications. 

Are There Any Side Effects or Risks?

There are no serious side effects for Gua sha treatments when provided by a medical professional that specializes in this treatment. The most common side effect is bruising, which tends to heal quickly and disappear within a few days after treatment. Infrequent side effects include minor bleeding or skin indentation at the treatment site. 

Gua sha is not recommended for people with certain medical conditions or who are taking certain drugs. People who have recently had surgery need to wait before beginning Gua sha treatments, usually for about six weeks after surgery. Patients taking blood thinners or who have an implant, such as a pacemaker, should avoid these treatments. Gua sha is typically not appropriate for people with medical conditions including infections, tumors, open wounds, blood clotting disorders, deep vein thrombosis, or other conditions affecting the skin or veins. 

How does TORQ PT utilize gua sha?

Here at TORQ PT, we offer Instrument Assisted Soft Tissue Mobilization (IASTM) as part of a comprehensive Physical Therapy treatment plan or with our Cup, Scrape, and Tape sessions. IASTM is a modernized form of gua, sha, involving a scraping motion using metal instruments on specific areas of the body. The benefits of IASTM mirror that of gua sha and have produced many positive results for our patients. 

The Takeaway

When used properly, Gua sha can provide an effective and safe alternative to other conventional treatments or can be used alongside conventional practices. Gua sha may provide healing and pain relief, especially for people who prefer to avoid medications, injections, or invasive surgeries. Gua sha can be used in conjunction with other alternative therapies and treatments as well.

Although the side effects are very minimal with proper treatment, Gua sha should be performed by a trained practitioner. Excessive force can cause pain, muscular strains, vascular trauma, severe bruising, or worsening of condition. More likely though, someone who is not trained in the practice of Gua sha will likely not be able to provide any functional results as the instruments must be used in a specific way.
