Diagnosis and treatment of posterior interosseous nerve syndrome using soft tissue manipulation therapy: a case study

Peripheral nerve entrapments of the upper and lower extremity are commonly seen in practice. Chronically repetitive movement patterns lead to constriction of the nerve due to the development of local fibrosis within the soft tissues surrounding the nerve which also affects nerve traction, mobility, and function. A case is presented of a patient with motor weakness in the wrist and hand in order to illustrate the diagnosis and treatment of posterior interosseous nerve (PIN) syndrome. Using Active Release Techniques Soft Tissue Management and Peripheral Nerve Release Systems) the patient's symptomatology was resolved. Soft tissue-based management in conjunction with neural gliding may be beneficial in the conservative management of PIN syndrome. Further research into the pathophysiology of nerve entrapments will have immediate impact on the management of neuropathies and likely result in emphasizing conservative management and rehabilitation rather than surgical intervention particularly in cases not involving denervation or paralysis.
