The anatomical structures vulnerable to acupuncture around the PC6 acupuncture point were investigated. Needles were inserted in PC6 of eight wrists from four cadavers to a depth of 2 cm, the forearms were dissected and the adjacent structures around the path of the needles were observed. The needles passed between the tendons of the palmaris longus and flexor carpi radialis muscles and then pe...

OBJECTIVE To investigate the accuracy of manual needle placement for injection of botulinum toxin type A into the forearm muscles of adults with spastic flexed wrist and clenched fist as a consequence of stroke. DESIGN Prospective clinical study. PATIENTS A total of 41 adults with chronic stroke who were scheduled to receive botulinum toxin type A injection into the following forearm muscle...

Abstract A subthreshold pulse of transcranial magnetic stimulation (TMS) on the motor cortex can modulate amplitude monosynaptic reflex (H-reflex) elicited in flexor carpi radialis (FCR) muscle, a method known as TMS-conditioning H-reflex. The purpose this study was to establish intersession reliability over course three sessions. Eleven healthy participants received either peripheral nerve (PN...

In 143 normal subjects latencies of H-reflexes of the flexor carpi radialis muscle were well correlated with arm lengths. In 32 patients with injury to cervical roots C5 to C8 it was shown that latencies were only abnormal in lesions of roots C6 or C7. It is suggested that in most instances root C6 or C7 and, probably both roots in some cases are involved in the reflex pathway. Repeat electroph...

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...

Voluntary contractions induce thixotropic changes in intrafusal muscle fibres and hence, by induction or removal of "slack", the background discharge and sensitivity of spindle endings to stretch is altered. This study assessed whether such changes also altered the "excitability" of the motor cortex. Eleven subjects performed a series of voluntary conditioning contractions of the wrist flexors ...

The aim of this paper is to propose an exploratory study on simple, accurate and 19 computationally efficient movement classification technique for prosthetic hand application. The 20 surface myoelectric signals were acquired from 2 muscles – Flexor Carpi Ulnaris and Extensor Carpi 21 Radialis of 4 normal-limb subjects. These signals were segmented and the features extracted using a 22 new comb...
