We used positron emission tomography (PET) to test the hypothesis that illusory movement of the right wrist activates the motor-related areas that are activated by real wrist movements. We vibrated the tendons of the relaxed right wrist extensor muscles which elicits a vivid illusory palmar flexion. In a control condition, we vibrated the skin surface over the processes styloideus ulnae, which ...

We examine mobile gesture interaction while the user is encumbered by holding bags and boxes. This is a frequent situation in everyday life and one that can cause problems when using mobile devices. A Fitts’ Law study was conducted to examine wrist rotation, a ‘hands free’ interaction method, to assess the effects of carrying objects on interaction performance. The aim was to understand if, and...

This study aimed to examine the effects of different taping pressures with or without external force on the maximum dorsal flexion angle (DFA). Twenty-two healthy male university students with >5 years of athletic experience participated. A qualified trainer wound a rigid tape thrice around subject’s wrist joint. Taping pressure was measured using the pressure measuring system AMI3037-SB. Indep...

Past studies have suggested that acupuncture may reduce spasticity in stroke survivors. We do not know, however, whether acupuncture may enhance the effect of strength training on motor function. This study compared upper-limb motor functional improvement in chronic stroke survivors who received a combination of acupuncture and strength training with that of subjects who received strength train...

[Purpose] The purpose of this study was to examine the effect of the Schroth method (three-dimensional convergence exercise) of emphasis of active holding on pain and Cobb's angle in patients with scoliosis. [Subjects and Methods] It applied the Schroth method program of emphasis of active holding individually to three subjects three time per week for 15 weeks. All subject were measured Cobb's ...

BACKGROUND Occupational computer use has been associated with upper extremity musculoskeletal disorders (UEMSDs), but the etiology and pathophysiology of some of these disorders are poorly understood. Various theories attribute the symptoms to biomechanical and/or psychosocial stressors. The results of several clinical studies suggest that elevated antagonist muscle tension may be a biomechanic...

BACKGROUND The quality of the floor is essential to the welfare of piglets as abrasions often are recorded in newborn piglets, and such lesions may lead to lameness. Apart from animal suffering, lameness contributes to losses in form of dead piglets, decreased growth, and increased use of antibiotics and manual labour. METHODS In a herd with three different farrowing systems, 37 litters (390 ...

The mechanical effect of a muscle following agonist-to-antagonist tendon transfers does not always meet the surgeon's expectations. We tested the hypothesis that after flexor carpi ulnaris (FCU) to extensor carpi radialis (ECR) tendon transfer in the rat, the direction (flexion or extension) of the muscle's joint moment is dependent on joint angle. Five weeks after recovery from surgery (tendon...

Background & Aims: Treatment of osteoporotic distal radius fracture with metaphyseal defect is often complicated by secondary displacement, because of posterior cortex comminution. The aim of this study was to investigate functional outcomes and advantages of injection of bone cement in stabilizing and maintaining this fracture reduction. Methods: This prospective study was performed on 20 ...
