Certified Hand Therapist Cynthia Larsen, OTR/L, CHT practices in Carlsbad from Palmer Way in the 92010 ZIP code near Palomar Airport Road, specializing in upper-extremity rehabilitation under NPI 1861441099. Post-surgical hand and wrist patients discharged from ambulatory facilities such as Jason Curry, MD Surgical Center in Carlsbad are referred to certified hand therapists for the structured rehabilitation protocols that restore grip strength, range of motion, and fine-motor dexterity following operative repair. The CHT credential, administered by the Hand Therapy Certification Commission, requires a minimum of 4,000 hours of direct hand-therapy clinical experience and passage of a comprehensive specialty examination covering anatomy, pathology, and treatment of the upper extremity from shoulder to fingertip. Musculoskeletal cases involving cervical-radiculopathy-related hand weakness or carpal-tunnel syndrome sometimes require parallel spinal evaluation through chiropractic providers such as West Coast Chiropractic Center Carlsbad, which addresses the cervical-spine component of referred upper-extremity symptoms. Highest-complexity interventions include custom thermoplastic orthosis fabrication for post-tendon-repair immobilization, progressive resistive exercise protocols following flexor-tendon-zone-II repair, and desensitization programs for complex regional pain syndrome of the hand using graded-motor-imagery and mirror-therapy techniques.
