“What are the differences between Gua Sha and the Graston technique?”

---

Both Gua Sha and Graston Technique involve using a tool to scrape the skin, a method broadly known as Instrument-Assisted Soft Tissue Mobilization (IASTM). However, they are fundamentally different in their origins, philosophies, and objectives.

Here is a comparison of the key differences:

Feature	Gua Sha (刮痧)	Graston Technique
Origin	Traditional Chinese Medicine (TCM).	Modern Western Physical Therapy/Sports Medicine (Developed in the U.S.).
Philosophy	Based on TCM principles: moving Qi (energy) and blood, and releasing “Sha” (stagnant blood, heat, or toxins).	Based on Western principles: identifying and breaking down fascial restrictions, adhesions, and scar tissue (fibrosis) to promote soft tissue healing.
Tools	Simple, smooth-edged instruments made of materials like jade, ceramic, buffalo horn, or stone.	Patented set of six surgical-grade stainless steel instruments. Certification is required to purchase and use them.
Technique	Long, broad, and unidirectional strokes over lubricated skin to “raise Sha.” Pressure varies from gentle (face) to firm (body).	Highly controlled, targeted strokes using specific instrument contours to detect fibrotic areas and treat them precisely.
Primary Goal	Holistic wellness, pain relief, detoxifying the body, and restoring internal balance.	Rehabilitation, treating specific musculoskeletal conditions (e.g., Achilles tendonitis, carpal tunnel), and restoring range of motion.
Visual Effect	Intended to cause petechiae (red or purple spots/bruising) known as “Sha.”	May cause minor redness (hyperemia), but the goal is not to produce bruising.
Practitioner	TCM practitioners, acupuncturists, or general wellness therapists.	Physical Therapists (PTs/DPTs), Chiropractors (DCs), or Athletic Trainers (ATCs) who have completed Graston certification.

Summary of Differences

1. Intent: Gua Sha focuses on energetic and circulatory balance (releasing Sha and stagnation), while Graston focuses on structural and mechanical repair (breaking up scar tissue and fascial restrictions).
2. Tools: Gua Sha uses simple, traditional tools; Graston uses specialized, patented stainless steel instruments.
3. Certification: Gua Sha is a general TCM practice; Graston is a trademarked technique that requires specific certification for legal use.
