FDA Registration
IASTM, Gua Sha, and muscle scraping tools are classified as ‘Therapeutic Manual Massagers’ under Physical Medicine. These devices, with the product code LYG, are Class I and exempt from premarket review and regulated under number 890.5660 by the Office of Neurological and Physical Medicine Devices.

Scope of Practice
The administration of Gua Sha or Instrument-Assisted Soft Tissue Mobilization (IASTM) is generally performed by licensed healthcare professionals, depending on the regulations in the specific region or country. The following professionals are commonly allowed to administer Gua Sha or IASTM:
1. Physical Therapists (PTs) – Trained to perform IASTM as part of rehabilitative therapy.
2. Chiropractors – Often use IASTM techniques in their practice for musculoskeletal issues.
3. Occupational Therapists (OTs) – May use IASTM as part of hand therapy or other treatments.
4. Massage Therapists – Some are trained in Gua Sha or IASTM, depending on their certification and state regulations.
5. Acupuncturists – Frequently perform Gua Sha as part of traditional Chinese medicine practices.
6. Athletic Trainers – May be trained to use IASTM techniques, especially in sports settings.
7. Licensed Physicians – In some cases, physicians may also administer these techniques if they have received proper training.
The specific scope of practice and the legality of administering these techniques can vary widely, so it’s essential for practitioners to be licensed and certified according to their local regulations.

FDA Requirement
All medical devices sold in the United States are regulated by the U.S. Food and Drug Administration (FDA). Any device manufactured, repackaged, relabeled, or imported for sale in the U.S. must comply with FDA regulations. Devices that pass the 510(k) review process are considered ‘cleared,’ while those meeting safety and effectiveness standards in the PMA process are ‘approved.’ Once cleared or approved by the FDA, the device can be marketed for sale and use in the United States.
If you are aware of a medical device being marketed in the U.S. without FDA registration, you can report it to the FDA.

What is stereolithography?
Stereolithography (SLA) is a 3D printing technology, also known as optical fabrication, photo solidification, or resin printing. This process creates models, prototypes, patterns, and production parts layer by layer using light to initiate a photochemical reaction. This reaction causes chemical monomers and oligomers to bond, forming durable polymers that make up the structure of the three-dimensional object. SLA is renowned for its ability to produce highly accurate and high-resolution parts.
Here’s how the SLA (Stereolithography) fabrication process works:
Technical Specifications Overview:
The Somos WaterShed XC 11122 material features a clear to translucent appearance with ABS-like properties, making it ideal for a variety of applications. It boasts a flexural strength of 69 MPa/KSI and an elongation at break of 15%, alongside a heat deflection temperature (HDT) at 0.46 MPa of 50°C. The standard resolution setup offers two build envelopes, with the large measuring 29” x 25” x 21” and the small 10” x 10” x 10”. Tolerances in the XY plane are maintained at +/- 0.005” for the first inch, with an additional +/- 0.002” for each subsequent inch, while in the Z plane, tolerances start at +/- 0.010” for the first inch, also adding +/- 0.002” per inch thereafter. Layer heights are set at 0.004” for the large build and 0.002” for the small. Feature resolution limits indicate that in the large build, features under 0.030” are at risk and those under 0.020” will not build, whereas in the small build, features under 0.020” are at risk and under 0.010” will not build. The minimum radial feature size is 0.035” for the large build and 0.030” for the small. These detailed parameters ensure that users can accurately assess the material’s suitability for complex designs, providing a reliable foundation for precision in advanced manufacturing applications.
