Severe hip joint motion restriction in a patient with diffuse idiopathic skeletal hyperostosis: A case report.

Rationale: Severe limitation of motion (LOM) in the spine occasionally occurs in patients with diffuse idiopathic skeletal hyperostosis (DISH). However, in extraspinal areas, significant LOM has rarely been reported. In this study, we report a patient with DISH who had severe motion restriction within both hip joints.

Abnormal spontaneous activities on needle electromyography and their relation with pain behavior and nerve fiber pathology in a rat model of lumbar disc herniation.

Study Design: This longitudinal experimental study was conducted to investigate electrophysiologic characteristics, pain behavior, and histological changes in a rat model of lumbar disc herniation.

Objective: To observe abnormal spontaneous activity (ASA) on needle electromyography (EMG) and to determine its relation with neuropathic pain behavior and histological changes longitudinally in a rat model of lumbar disc herniation.

Summary Of Background Data: Needle EMG is generally performed to determine the existence and the degree of radiculopathy caused by disc herniation.
