Jennifer Gruenhagen, DPT, PhD brings vestibular and balance-disorder expertise to Chula Vista's Eastlake corridor from her practice at 1400 East Palomar Street, treating BPPV, vestibular neuritis, labyrinthitis, and post-amputation gait dysfunction under California PT license #34161. Her specialization in return-to-sport rehabilitation parallels the athletic-recovery programming at Sports Performance Physical Therapy, which focuses on sport-specific reconditioning for competitive athletes in the Chula Vista area near the Elite Athlete Training Center. Gruenhagen's dual role as a university-level DPT faculty member informs an evidence-based treatment model that integrates current vestibular-rehabilitation research into clinical practice for patients referred from otolaryngology and neurology providers. Vestibular hypofunction cases requiring audiological co-management often parallel the diagnostic workup at South Bay Hearing & Balance, which performs the caloric and rotary-chair testing that informs PT treatment parameters. Canalith repositioning procedures for posterior-canal BPPV utilize the Epley and Semont maneuvers confirmed by Dix-Hallpike provocative testing to resolve otoconia displacement within one to three clinical sessions.
