Usable three-dimensional (3D) interaction techniques are difficult to design, implement, and evaluate. One reason for this is a poor understanding of the advantages and disadvantages of the wide range of 3D input devices, and of the mapping between input devices and interaction techniques. We present an analysis of Pinch GlovesTM and their use as input devices for virtual environments (VEs). We...

Objectives: Carpal tunnel syndrome (CTS) is a common peripheral entrapment neuropathy with squeezing of the median nerve and the patient is unable to function properly. There are different physiotherapy interventions for the management of these patients and recently, shock wave therapy and low-power laser (LPL) have been widely used, but there is no strong evidence comparing the effect of shock...

A biased electrode is used in the Madison Symmetric Torus ~MST! reversed-field pinch @Fusion Technol. 19, 131 ~1991!# to manipulate plasma flow in order to study flow damping and momentum transport. Finite radial conductivity allows a radial current, which provides the toroidal torque that spins up the plasma. The applied torque is balanced by a viscous force that opposes toroidal flow accelera...

The dynamics of an idealized, infinite, MIT-type flux tube is followed in time as the interior evolves from a pure gluon field to a q q plasma. We work in color U(1). q q pair formation is evaluated according to the Schwinger mechanism using the results of Brink and Pavel. The motion of the quarks toward the tube endcaps is calculated by a Boltzmann equation including collisions. The tube under...

This study investigates the relationship of hand use to the deforming hand joint changes of rheumatoid arthritis. Measurements of metacarpophalangeal lateral mobility, loss of metacarpophalangeal hyperextension, thumb metacarpophalangeal range of motion, and lateral pinch strength were statistically compared across dominant and nondominant hands of 51 adult subjects who had definite or classica...

INTRODUCTION In Parkinson's disease (PD), a resting tremor of the thumb may affect the flexor pollicis longus (FPL) and influence hand functions. We investigated the relationship between FPL tendon thickness and hand function in PD patients and compared these characteristics with those in healthy controls. METHODS The hand grip and pinch strengths were measured. The participants completed the...

PURPOSE To evaluate the efficacy of the technique of dual Mini TightRope suspensionplasty for treatment of trapeziometacarpal joint arthritis. METHODS We conducted a retrospective study investigating the use of a dual Mini TightRope suspensionplasty technique from 2010 to 2013 at a single institution. We identified 11 patients (12 thumbs). Grip and pinch strength, thumb range of motion, and c...

We apply QCD Finite Energy Sum Rules to the scalar-isoscalar current to determine the lightest uu+ dd meson in this channel. We use ‘pinch-weights’ to improve the reliability of the QCD predictions and reduce the sensitivity to the cut-off s0. A decaying exponential is included in the weight function to allow us to focus on the contribution from low mass states to the phenomenological integral....
