Double crush syndrome: chiropractic care of an entrapment neuropathy

Upton and McComas first proposed the existence of the "double crush syndrome." Their hypothesis was that neural function could be impaired when single axons, having been compressed in one region, become especially susceptible to damage in another. A case report of a man with both cervical radiculopathy and carpal tunnel syndrome, i.e., "double crush syndrome" is presented. Conservative management consisting of chiropractic manipulative therapy as well as ultrasound, electrical nerve stimulation, traction and a wrist splint is outlined. The experimental basis, clinical evidence, etiology, symptomatology and findings of this condition are discussed.
