QUESTION What is the effectiveness of 12 weeks of nightly stretch in reducing thumb web-space contracture in people with neurological conditions? DESIGN Assessor-blinded, randomised controlled trial. PARTICIPANTS Forty-four (one dropout)community-dwelling patients with a neurological condition (14 stroke, 7 traumatic brain injury, 23 spinal cord injury) who had uni or bilateral thumb web-sp...

Thumb duplication is a rare anomaly. Here we describe two neonatal cases of thumb duplications, one type II and the other IV. Seven types have been described in medical literature. Radiological assessment important differentiating between these types.

We present a simple kinematic model of the thumb for the animation of virtual characters. The animation is made through a pure kinematics approach, thus needing very precise limitations on the rotations of the thumb to be realistic. The thumb is made opposable thanks to the addition of two bones simulating the carpometacarpal complex.

BACKGROUND For surgical reconstruction of lateral pinch following tetraplegia, the function of the paralyzed flexor pollicis longus is commonly restored. The purpose of this study was to investigate if one of the intrinsic muscles could generate a more suitably directed thumb-tip force during lateral pinch than that of flexor pollicis longus. METHODS Endpoint force resulting from 10 N applied...

Finger-thumb coordination is crucial to manual dexterity but remains incompletely understood, particularly following neurological injury such as stroke. While being controlled independently, the index finger and thumb especially must work in concert to perform a variety of tasks requiring lateral or palmar pinch. The impact of stroke on this functionally critical sensorimotor control during dyn...

BACKGROUND Thumb sucking habits make up the majority of oral habits. While thumb sucking is considered normal during the first two years of life, if it is not controlled and persists beyond the preschool period it may cause deleterious effects on dentofacial structures. Reminder therapy using Bluegrass appliance has been proven successful to intercept thumb sucking habit. CASE REPORT We prese...

TRAUMATIC amputation of the thumb is a particularly severe hand injury, because of the unique functional role of the thumb, and several methods exist for reconstruction of the thumb, all of which have disadvantages. Microvascular technique allows the transfer of a block of tissue from one site to another, by anastomosis of vessels with a known vascular territory to the vessels in the recipient ...

The aim of this study is to establish whether the thumb is represented independently of the palm. An exogenous spatial cueing paradigm was used, where participants had to detect a tactile stimulus that could appear on the proximal and distal phalanges or metacarpus of the thumb (thenar area; Experiment 1) and the metacarpus of the thumb or hypothenar area of the palm (Experiment 2) of the left ...

Bowler's thumb is a rare perineural fibrosis involving the ulnar digital nerve of the thumb. Affected patients present with pain, neuropathy, and mass lesion. The condition is caused by chronic repetitive impaction of the ulnar soft tissues of the thumb against the thumbhole of a bowling ball. In our case, MRI showed decreased signal intensity on both T1- and T2-weighted images surrounding an e...
