Design: Descriptive study SETTING: Department of physical medicine and rehabilitation.
Participants: Healthy individuals (age, 20-70y) without any diseases (N=29; 15 men, 14 women; 58 forearms).

Methods: Thirty-one healthy subjects without a history of trauma or neurological disease were recruited. For the orthodromic procedure, the recording electrode was attached immediately superior to the supraorbital notch.
The holotype of Deinocheirus mirificus was collected by the 1965 Polish-Mongolian Palaeontological Expedition at Altan Uul III in the southern Gobi of Mongolia. Because the holotype consists mostly of giant forelimbs (2.4 m in length) with scapulocoracoids, for almost 50 years Deinocheirus has remained one of the most mysterious dinosaurs.

Objective: The aim of this study was to determine the criteria for ultrasonographic measurement of the cross-sectional area (CSA) of the median nerve and differential diagnosis of patients with carpal tunnel syndrome (CTS) with or without diabetic polyneuropathy (DPN).
Design: One hundred eighty-seven patients were divided into five groups: healthy controls, CTS, diabetes with CTS but without DPN, DPN only, and both DPN and CTS. The CSAs of the median nerve were measured at four levels, and cutoff values to diagnose CTS with DPN were obtained.
Superficial peroneal neuropathy is a known complication of foot and ankle arthroscopy. A 27-year-old man developed pain and paresthesia on the medial side of the dorsum of his left foot after ankle arthroscopy. An electrodiagnostic study revealed conduction abnormality in the medial branch of superficial peroneal nerve, in which neuroma-in-continuity was subsequently detected by ultrasonography.

Methods: Sixty diabetic patients, 30 patients with carpal tunnel syndrome (CTS) and 30 healthy volunteers participated. The participants were divided into 4 groups: Control Group; Group I, diabetic patients without diabetic polyneuropathy (DPN); Group II, diabetic patients with DPN; and Group III, patients with CTS.
Objective: This study is designed to derive a normative database for nerve conduction values of the ulnar nerve in the wrist.
Methods: Ulnar nerve study at the wrist (UNSW) was performed in 204 hands of 102 control subjects. The UNSW was composed of motor and sensory tests.
