PURPOSE The aim of this study was to explore the total and regional grip forces in the hand when propelling two different manual one arm drive wheelchairs: the Neater Uni-wheelchair (NUW) and a foot steered Action3 wheelchair. METHODS 17 nondisabled users were randomly assigned to each wheelchair to drive around an indoor obstacle course. The Grip, a multiple sensor system taking continuous m...

BACKGROUND Wrist disorders are common in force demanding industrial repetitive work. Visual assessment of force demands have a low reliability, instead surface electromyography (EMG) may be used as part of a risk assessment for work-related wrist disorders. For normalization of EMG recordings, a power grip (hand grip) is often used as maximal voluntary contraction (MVC) of the forearm extensor ...

The aim of this study was to investigate aging-related changes in the contribution of genetic and environmental influences to hand-grip strength in late adulthood. Subjects in this study are 152 intact twin pairs (77 monozygotic and 75 dizygotic pairs) from the National Heart, Lung, and Blood Institute Twin Study assessed repeatedly for hand-grip strength at mean ages of 63 and 73 yr. Structura...

BACKGROUND The complications associated with type 2 Diabetes Mellitus (DM) may cause functional impairment in older people. Recently it has been proved that motor dysfunction in the form of skeletal muscle dysfunction does occur in type II DM. However very few studies have assessed the upper limb skeletal muscle dysfunction. OBJECTIVES The study was aimed to assess the hand grip strength, end...

The aim of the present study was to evaluate the grip strength between the two sides for the right and left handed male and female collegiate Indian population, as grip strength provides an objective index for the functional integrity of upper extremity. The study is based on151 males (103 right handed and 48 left handed) and 152 females (129 right handed and 23 left handed) collegiate populati...

This paper proposes H, an anthropomorphic prosthesis hand with 5 fingers and human hand size. It consists of the combination of direct actuated and underactuated system for a dexterous grip. The H also has modularized 2 DOF of MCP mechanism in a thumb for power grip. The adduction-abduction and antepositon-retroposition movements are generated by this structure of thumb which is the function of...
