CHT Peripheral Nerve Injury 2025/2026 | 130+ Solved Questions on Nerve Anatomy, Seddon & Sunderland Classifications, Brachial Plexus, Entrapment Syndromes & Sensory Rehab

This comprehensive CHT exam prep guide for 2025/2026 offers 130+ high-yield questions with correct answers, centered on peripheral nerve anatomy, injury mechanisms, clinical syndromes, and evidence-based rehabilitation. Perfectly tailored for Certified Hand Therapist (CHT) candidates, this resource presents in-depth coverage of both theoretical foundations and practical applications, helping clinicians diagnose, treat, and manage nerve-related conditions in the upper extremity. Key content areas include: Peripheral nerve structure: endoneurium, perineurium, epineurium functions Spinal cord pathways: afferent vs efferent fibers, dorsal/ventral roots, cervical levels Brachial plexus anatomy & syndromes: Erb’s palsy (C5–C6), Klumpke’s palsy (C8–T1), Horner’s syndrome Nerve injury classification: Seddon (Neuropraxia, Axonotmesis, Neurotmesis) and Sunderland I–V with prognosis, healing rates, and functional implications Anastomoses: Martin-Gruber, Marinacci, Riche-Cannieu, Berretini connections Entrapment syndromes: Pronator syndrome, AIN syndrome, PIN syndrome, Radial Tunnel, Wartenberg’s syndrome Thoracic Outlet Syndrome: compression sites (scalene interval, costoclavicular, subcoracoid) and provocative tests (Adson’s, Roos, Wright’s, Halstead) Myotomes, dermatomes, and reflexes: segmental innervation C2–T1 with associated muscle actions and sensory zones Sensory testing and reeducation: Semmes-Weinstein, tuning fork tests, 2-point discrimination, stereognosis Phased rehabilitation: protection, sensory stimulation, motor retraining, adaptive orthoses and functional reintegration This resource is ideal for: Candidates preparing for the Certified Hand Therapist (CHT) exam Occupational and physical therapy students studying upper extremity neurorehab Hand therapists and orthopedic clinicians focusing on nerve injuries and post-op care Professionals reviewing nerve entrapment syndromes, diagnostic signs, and motor/sensory rehab Well-structured and clinically grounded, this guide blends academic rigor with hands-on clinical relevance, ensuring confidence in both exam settings and real-world treatment scenarios.
