Mason Chiropractic has practiced chiropractic neurology on Baltimore Drive in La Mesa's Fletcher Hills corridor since 1987, with its principal holding DACAN (Diplomate of the American Chiropractic Academy of Neurology) board certification and California QME (Qualified Medical Evaluator) designation. Neurological examination protocols — including cranial-nerve assessment, cerebellar function testing, and dermatomal sensory mapping — distinguish the practice from general-chiropractic offices and require cross-referral with Grossmont Medical Plaza for MRI and nerve-conduction studies. The QME designation authorizes independent medical evaluations for California workers' compensation cases, generating forensic-grade impairment reports that carry evidentiary weight in administrative hearings. Clinical treatment addresses fibromyalgia, carpal tunnel syndrome, whiplash-associated disorder, and chronic low-back pain through neurologically informed adjustment sequences calibrated to each patient's functional-neurology findings. Athletic patients from contact-sport disciplines, including grapplers training at Jiu Jitsu Foundation, present with cervical and thoracic subluxation patterns that require sport-specific force-vector analysis before manipulation. Highest-complexity engagements involve QME impairment evaluations requiring AMA Guides to the Evaluation of Permanent Impairment methodology, whole-person impairment calculation, and apportionment analysis for multi-injury workers' compensation claims.
