Part of the Physical Rehabilitation Network founded in 1991, PRN Physical Therapy - La Mesa operates from 5905 Severin Drive with certified hand therapy, vestibular rehabilitation, and spine-care programs serving the broader Grossmont area. This location's certified hand therapy program treats post-surgical tendon repairs, fracture fixations, and custom splinting alongside orthopedic and vestibular rehabilitation, drawing referrals from the same musculoskeletal-care network that includes spinal-alignment providers like San Diego Chiropractic Doctors. PRN's minority-equity partnership model allows the La Mesa clinic's treating therapists to hold ownership stakes in the practice while centralized revenue-cycle management, human resources, and business development operate at the network level across 200-plus clinics in 16 states. Dry needling, manual therapy, aquatic therapy, and ergonomic assessment expand the treatment arsenal beyond conventional exercise-based protocols, addressing neurological, vestibular, and chronic-pain populations alongside standard orthopedic caseloads. Temporomandibular joint dysfunction and cervicogenic headache protocols coordinate frequently with dental and maxillofacial providers, including practices like Espire Dental where occlusal-splint therapy and physical rehabilitation often run in parallel. The clinic's highest-acuity hand-therapy cases involve zone-II flexor tendon repair rehabilitation requiring controlled-motion protocols, custom thermoplastic dorsal-blocking splints, and staged tendon-gliding exercises calibrated to healing-tissue tensile thresholds.
