Collection: Sai Therapeutic Brands

OTC, CSX, and Touch are three separate Sai Therapeutic Brands product lines with different purposes. OTC focuses on orthopedic braces and supports for joints and injuries, CSX focuses on athletic compression socks and sleeves for active performance and recovery, and Touch focuses on fashion-patterned compression knee-highs for everyday wear. All three are manufactured by Surgical Appliance Industries, a Cincinnati company with roots going back to 1893, but each line has its own distinct focus.

OTC takes its name from the Ohio Truss Company, Surgical Appliance Industries' original name when it was founded in 1893. Today the OTC line is designed for therapeutic performance and everyday comfort across several body areas, including:

• Wrist & Hand: Wrist splints, wrist-thumb splints, thumb immobilizers, and arthritis gloves.
• Knee: Knee stabilizers, hinged and orthopedic knee supports, knee wraps, and patellar stabilizers.
• Ankle: Ankle braces, stirrup splints, and ankle supports with straps or gel inserts.
• Back & Abdomen: LS supports, sacro braces, abdominal binders, and hernia supports.
• Neck & Shoulder: Cervical collars, cervical traction kits, clavicle straps, and shoulder immobilizers.
• Elbow: Elbow straps, night splints, and supports with gel inserts.

The right OTC product depends on the specific joint or area needing support, and your healthcare provider's recommendation when treating an injury or condition.

CSX was launched in 2014, building on Sai Therapeutic Brands' existing expertise in braces and supports to bring that same engineering to athletic compression. CSX compression socks and calf sleeves are available at CompressionSale in 15-20 mmHg and 20-30 mmHg, depending on the style, using breathable, moisture-wicking materials to support performance, muscle stability, and post-activity recovery. Check each product page for its exact compression level and sizing.

Touch compression knee-highs are available in fashion patterns including argyle, herringbone, fine checkered, and ribbed designs, in both men's and women's styles. Backed by the same Sai Therapeutic Brands family that manufactures OTC and CSX, Touch combines graduated compression with knit patterns designed to look more like everyday dress socks than traditional clinical compression hosiery.

OTC braces and supports are typically sized by the specific body measurement for that product, such as wrist circumference for a wrist splint or knee circumference for a knee support, so check the size chart for the exact product before ordering. CSX and Touch compression socks are sized similarly to other compression hosiery, based on ankle and calf circumference and shoe size. Because sizing varies by product and line, comparing your measurements against the specific product's size chart is the most reliable way to get the right fit.
