Unusual Motor Hand Neuropathies: Causes, Diagnosis, and Evaluation of Motor Impairments.

Background Isolated hand motor nerve injuries, specifically those affecting the recurrent motor branch of the median nerve and the deep motor branch of the ulnar nerve, are rarely reported in medical literature. Diagnosing and quantifying these injuries pose significant challenges due to their uncommon nature and the variety of mechanisms that can cause them. Methodology This study reviews six unusual cases of isolated damage to the recurrent motor branch of the median nerve and the deep motor branch of the ulnar nerve, including cases with combined injuries.

Significance of A-waves in Isolated Calf Pain as a Manifestation of Radicular Pain During F-wave Studies: A Case Report.

Although isolated lower leg pain (LPP) without neurological deficit is frequently encountered in clinical practice, some of its aspects remain underexplored in the literature. There is contrasting evidence supporting the use of late responses, namely, F-waves and A-waves, in the assessment of nerve root damage. We describe the case of a 29-year-old female who presented with pain in the left calf.

Distal Acquired Demyelinating Symmetric Neuropathy Associated with Decreased Electrical Excitability of the Femoral Nerves.

There are many phenotypic variants of chronic inflammatory demyelinating polyneuropathy. An Ancient Greek aryvallos painted c. 480-450 BC, now on display at the Louvre museum, was meticulously studied regarding its painted surface, which presents an outpatient clinic in Ancient Greece.

Severe Paraproteinemic Demyelinating Neuropathy With Impaired Excitability of the Distal Segments of the Peripheral Nerves.

We report clinical and detailed nerve conduction findings in case of polyneuropathy associated with kappa light chains monoclonal gammopathy of undetermined significance with progression to lymphoproliferative disorder. A 55-year-old man had a predominantly distal, chronic (5 years duration), slowly progressive, symmetric, predominantly sensory impairment with sensory ataxia, and mild weakness. M protein was identified by serum protein electrophoresis.

Radial motor nerve conduction studies in the upper arm.

Introduction: The main goal of this study was to determine the contribution of the anterior forearm muscles to the compound muscle action potential (CMAP) recorded from the extensor digitorum (ED) after proximal stimulation.

Methods: Twenty-one healthy volunteers and 114 patients with compressive and traumatic radial neuropathies were examined. Stimulation was carried out at six different points: distal third of the upper arm; Erb's point; axilla; medial upper arm; antecubital fossa; and ulnar groove.
