Isolated lesions of the posterior interosseous nerve of the forearm are uncommon. Most follow injury to the elbow region The clinical features of a long-standing lesion of the nerve are wasting of the posterior forearm muscles (excepting brachio-radialis and extensor carpi radialis longus), diminution or loss of active extension of the fingers at the metacarpo-phalangeal joints, and weakness or...

Fractures of both the radius and ulna are usually treated with two separate incisions and rarely with one single incision. However, both methods have disadvantages. For this we describe a relatively safe single straight posterior incision for exposure of the whole shafts of both the radius and ulna with the forearm rested on a board across the chest. This procedure was used in 116 forearms in 1...

Purpose: To develop a musculo-skeletal dynamic model for simulating hand grasp by means of FES in paretic hand. Methods: The skeletal model, which consisted of humerus, radius, ulna and bones of hand, was developed from CT data of. The muscle model, which had been designed by Hase, was developed about flexor carpi ulnaris, felxor carpi radialis, extensor carpi ulnaris, extensor carpi radialis l...

Since 1895, when de Quervain first described stenosing tenovaginitis of the tendons of abductor pollicis longus and extensor pollicis brevis at the radial styloid, a number of similar lesions have been described around the wrist joint. The tendons involved include extensor digiti minimi (Drury 1955), extensor carpi ulnaris (Dickson and Luckey 1948), flexor carpi radialis (Fitton, Shea and Goldi...

The aim of this study was to test the hypothesis in the literature that torque resistance of parkinsonian rigidity is the difference between the independent contributions of stretched and shortened muscles. The hypothesis was tested using muscle-specific stretch-shortening (MSSS) EMG ratio in this study. Nineteen patients with idiopathic Parkinson's disease (PD) and 18 healthy subjects (the mea...

[Purpose] This study investigated the difference in muscle activation of the dominant upper extremity in right-handed and left-handed persons during writing. [Subjects] There were 36 subjects (16 left- handers/ 20 right- handers), and the study was conducted from 03/01/2012 to 30/3/2012. [Methods] Six electrodes were attached to the FCU (flexor carpi ulnaris), FCR (flexor carpi radialis), ECU (...

[Medical Research Council (MRC) 2–3] was detected in the triceps brachii, f lexor carpi ulnaris and median nerve-innervated hand muscles. The flexor carpi radialis and ulnaris, extensor carpi ulnaris and finger flexors were mildly impaired. The shoulder girdle muscles, the biceps brachii, brachioradialis and extensor carpi radialis were spared. The muscle stretch reflexes were normal, except fo...
