Brachial amyotrophic diplegia (BAD) is a subtype of sporadic lower motor neuron disease (LMND) presenting with adult onset, mainly in men, and remaining largely restricted to proximal arm and shoulder girdle muscles without involvement of the lower limbs or appearance of pyramidal signs. 1,2 Mutations in the cop-per/zinc superoxide dismutase (SOD1) gene have been described in familial cases of ...
Ulnar nerve lesions at the elbow can usually be recognized by a characteristic combination of physical signs. In the hand, there is wasting and weakness of ulnar-innervated muscles with or without sensory loss of appropriate distribution; in the forearm there is often weakness of the ulnarinnervated portion of the flexor digitorum profundus and sometimes of the flexor carpi ulnaris. Further con...
To define the anatomical relationships of the nerves to the common arthroscopy portals at the elbow an arthroscope was introduced into 20 cadaver elbows and the positions of the nerves were then determined by dissection. In all cases the posterior interosseous nerve lay close to the radiohumeral joint and to the anterolateral portal. Pronation of the forearm displaced the nerve away from the ar...
OBJECTIVE The startle reflex elicits involuntary release of planned movements (startReact). Following stroke, startReact flexion movements are intact but startReact extension movements are impaired by task-inappropriate flexor activity impeding arm extension. Our objective was to quantify deficits in startReact elbow extension movements, particularly how these deficits are influenced by impairm...
OBJECTIVE The aim of this study was to investigate and compare the conduction parameters of nerve bundles of median and ulnar nerves that innervate proximal and distal muscles. SUBJECTS AND METHODS Thirty male and 30 female healthy volunteers between 18 and 70 years of age were enrolled in the study. The conduction parameters were recorded from the proximally located flexor carpi ulnaris, pro...
Torque-angle relations at the elbow and ankle joints of relaxed normal controls and patients with hemiparetic stroke were compared. Low velocity flexion/hold/extension angular perturbations were applied to the joint under examination. The resulting torque-angle profiles described a hysteresis loop with similar slopes during the extension and flexion stages but separated by a vertical torque off...
In total brachial plexus palsy, fingers flexion restoration is a real challenge. Nerve surgery can generally restore shoulder abduction and elbow flexion. However, results of nerve grafts or nerve transfers are generally poor for hand function. As a matter of fact, the long distance between nerve sutures and terminal nerve branches in muscles decreases the rate of reinnervation. When finger fle...
