We recorded motor-evoked potentials (MEPs) to transcranial magnetic stimulation from the right opponens pollicis (OP) muscle while participants observed an experimenter operating two types of pliers: pliers opened by the extension of the fingers and closed by their flexion ("normal pliers") and pliers opened by the flexion of the fingers and closed by their extension ("reverse pliers"). In one ...

In order to study the interaction between proprioceptive information and motor imagery, we herein investigate how compatible and incompatible postural signals influence corticospinal excitability during the mental simulation of hand movements. Subjects were asked to imagine themselves joining the tips of the thumb and the little finger while they maintained one of the two following hand posture...

An AB single-subject research design was used to assess the effectiveness of a short thumb opponens splint on hand function in a 4-year-old girl with cerebral palsy. Baseline data for active range of motion, grip and pinch strength, grasp patterns, the Box and Block Test of manual dexterity (Mathiowetz, Voland, Kashman, & Weber, 1985), and 1-in. cube stacking were collected twice a week for 4 w...

BACKGROUND Functional loss is a common complication of the fractured distal part of the radius. The purpose of the present study was to determine if the moment arms of the first dorsal extensor compartment are altered by distal radial fracture malunion. We hypothesized that the moment arms of the abductor pollicis longus and extensor pollicis brevis are significantly affected by dorsal angulati...

OBJECTIVE To determine the outcome and devise a protocol for emergency management of cut injuries in Flexor Zone 5 of hands. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of Plastic Surgery and Burn Unit, Mayo Hospital, KEMU, Lahore, Pakistan, from January 2009 to March 2013. METHODOLOGY All patients above 12 years of age with single sharp cut injuries in Flexor Z...

Rupture of the flexor pollicis longus tendon is a major complication after volar locking plate fixation of distal radius fracture. This study used ultrasonography to assess the flexor pollicis longus tendon and intermediate tissue. The study assessed 27 patients (28 wrists) who underwent removal of the volar locking plate. Before plate removal, radiography and ultrasonography were performed to ...
