The monofilament test (MFT) is a reliable method to assess sensory nerve function in leprosy and other neuropathies. Assessment of the radial cutaneous and sural nerves, in addition to nerves usually tested, can help improve diagnosis and monitoring of nerve function impairment (NFI). To enable the detection of impairments in leprosy patients, it is essential to know the monofilament threshold ...

This study seeks to extend the observations of previous studies of projection of primary afferent fibres from the forelimb nerves and muscles to the external cuneate nucleus (ECN) of mammals using a neurotoxic lectin, Ricinus communis agglutinin (RCA) to achieve chemical ganglionectomy of the dorsal root ganglia. Following intraneural injection of RCA into the three main forelimb nerves, namely...

OBJECTIVE To investigate the spatial pattern of lesion dispersion in posterior interosseous neuropathy syndrome (PINS) by high-resolution magnetic resonance neurography. METHODS This prospective study was approved by the local ethics committee and written informed consent was obtained from all patients. In 19 patients with PINS and 20 healthy controls, a standardized magnetic resonance neurog...

Nerve transfers for peripheral nerve injuries have become increasingly popular over the past two decades. While techniques ulnar repair been well-documented, more recent median and radial branch reinnervation are still being explored. This review describes outcomes of common emerging distal branches nerves.

Recognizing the arterial variations of human upper extremities is of potential clinical practice because this area is involved in arterial handling and invasive medical procedure. During dissection of the left upper limb of a 35-year-old male embalmed cadaver, we saw brachial artery bifurcation in the middle third of proximal portion of the arm. Its medial branch descended along the medial side...

The somatosensory cortex of primates contains patch- and bandlike aggregates of neurons that are dominantly activated by cutaneous inputs from the radial, median, and ulnar nerves to the hand. In the present study, the area 3b hand cortex of adult monkeys was mapped immediately before and after combined median and ulnar nerve transection to evaluate the consistency, extent, and location of earl...

INTRODUCTION To date, only scant data has been reported regarding the anatomy of the radial nerve and profunda brachii artery and their relationships while within the triangular interval of the posterior arm. As this area has recently gained attention for using motor branches of the triceps muscle for nerve transfers, the present study was conducted. MATERIALS AND METHODS Fifteen adult cadave...

1348 CMAJ, September 6, 2011, 183(12) © 2011 Canadian Medical Association or its licensors Isolated radial nerve palsy in the newborn is uncommon. However, pediatricians and primary care physicians need to be aware that it has a good prognosis, particularly if the history and clinical examination suggest a palsy related to intrauterine pressure. In this issue of CMAJ, Alsubhi and colleagues des...

Objective: The purpose of this study was to assess the measurement nerve gliding, resulting from joint motion and changes upper extremity position. Methods: extremities ten fresh human cadavers were dissected delineate relationship between positioning gliding distance nerves. Nerve mobilization – stretching therapy (SMG) techniques are mentioned in literature for each radial, medial ulnar excur...

Electrical activity in the radial nerve cord of the sea urchin Diadema setosum has recently been reported by Takahashi (1964), who recorded nerve impulses following direct photic stimulation of the isolated nerve cord. No other electrical activity has been recorded from sea-urchin nervous systems. The following is a report on electrical phenomena in the isolated radial nerve cord and ampullae o...
