For Applied Functional Science rehabilitation near Sharp Grossmont Hospital in La Mesa, Brittany Hollenbeck treats patients at Rehab United's 7,200-square-foot Fletcher Parkway clinic. The facility's 60-plus feet of indoor turf and mezzanine-level training floor support multi-plane movement progressions used in post-surgical knee and shoulder recovery, a functional-loading methodology also incorporated into the orthopedic protocols at Synergy Orthopedics Physical Therapy. Rehab United, founded in 2003, built its clinical model on Applied Functional Science's biomechanical cause-and-effect approach, evaluating kinetic-chain dysfunction rather than isolated symptom sites. Vestibular therapy and BPPV screening address dizziness, vertigo, and balance dysfunction through canalith-repositioning maneuvers and gaze-stabilization drills, complementing the lymphatic-drainage and acupressure work at Lex Acupressure & Lymphatic Drainage on Jackson Drive. The clinic's highest-acuity service line involves ACL-reconstruction rehabilitation using progressive closed-kinetic-chain loading on the turf surface, blood-flow-restriction training for quadriceps hypertrophy, and force-plate-based return-to-sport testing protocols.
