Workshop: clinical implications for clinicians treating patients with non-specific arm pain, whiplash and carpal tunnel syndrome

Nerve sheath inflammation without significant axonal degeneration can result in c fibres (both axons in continuity and the nervi nervorum) becoming spontaneously active and mechanically sensitive. This may help explain the painful responses when examining neural dynamics in patients with non specific arm pain, carpal tunnel syndrome and arm pain following whiplash injury, when longitudinal nerve excursion (measured using ultrasound imaging), appears to be within normal ranges. These findings have implications for the clinical examination and treatment of these patients groups.
