Is Abnormal Electrodiagnostic Finding Related to the Cross-Sectional Area of the Nerve Root in Cervical Radiculopathy?

Objective: To assess the relevance of electrodiagnosis (EDX) in the cross-sectional area (CSA) of the nerve root of patients with cervical radiculopathy (CR) by using high-resolution ultrasonography (HRUS).

Methods: The CSAs of the cervical nerve roots at C5, C6, and C7 were measured bilaterally using HRUS in 29 patients with unilateral CR whose clinical symptoms, magnetic resonance imaging (MRI) findings, and EDX results corresponded with each other (CR-A group), and in 26 patients with unilateral CR whose clinical symptoms and MRI findings matched with each other but did not correspond with the EDX findings (CR-B group).

Results: The CSA of the affected side in each nerve root was significantly larger than that of the unaffected side in both the CR-A and CR-B groups.

Change in Center of Pressure Progression in the Foot Provides Clues for Functional Improvement of the More Affected Lower Limb During Post-stroke Gait Rehabilitation.

Objective: The aim of this study was to determine the clinical significance of the anterior-posterior displacement of the center of pressure in the foot (apCoP) in post-stroke gait rehabilitation.

Design: This observational study was conducted in a tertiary hospital. Forty-two subacute post-stroke patients were included.

Risk Assessment of Injury to Palmar Cutaneous Branch of the Median Nerve Using High-Resolution Ultrasound.

Objective: To evaluate the relationship between the palmar cutaneous branch of median nerve (PCBMN) and surrounding anatomical structures by using high-resolution ultrasound (HRUS) to assess the risk of PCBMN injury.

Methods: The PCBMN course and the characteristics of bilateral distal forearms and wrists of 30 healthy volunteers were identified. The distance between PCBMN and other anatomical structures at three different levels along its course were measured using HRUS.

Retrospective study on the impact of ulnar nerve dislocation on the pathophysiology of ulnar neuropathy at the elbow.

Introduction: High resolution ultrasonography (US) has been used for diagnosis and evaluation of entrapment peripheral neuropathy. Ulnar neuropathy at the elbow (UNE) is the second most common focal entrapment neuropathy. The ulnar nerve tends to move to the anteromedial side and sometimes subluxates or dislocates over the medial epicondyle as the elbow is flexed.
