Investigation of Grip Force, Normal Force, Contact Area, Hand Size, and Handle Size for Cylindrical Handles
Objective: To investigate relationships among grip forces, normal forces, contact area for cylindrical handles, handle diameter, hand size, and volar hand area. Background: Data describing thoseExpand

The effect of torque direction and cylindrical handle diameter on the coupling between the hand and a cylindrical handle.
Pheasant and O'Neill's torque model (1975) was modified to account for grip force distributions. The modified model suggests that skin friction produced by twisting an object in the direction ofExpand

Phalanx force magnitude and trajectory deviation increased during power grip with an increased coefficient of friction at the hand-object interface.
This study examined the effect of friction between the hand and grip surface on a person's grip strategy and force generation capacity. Twelve young healthy adults performed power grip exertions onExpand

Contribution of intracortical inhibition in voluntary muscle relaxation
Terminating a voluntary muscle contraction is an important aspect of motor control, and yet, its neurophysiology is unclear. The objective of this study was to determine the role of short-intervalExpand

Delays in grip initiation and termination in persons with stroke: effects of arm support and active muscle stretch exercise.
Stroke survivors' difficulty in releasing grasped objects may be attributable not only to impaired finger extension but also to delays in terminating activity in the gripping flexor muscles. ThisExpand

Biomechanical analysis for handle stability during maximum push and pull exertions
This study investigated the effect of handle stability on maximum push/pull force. It was hypothesised that people apply force in directions deviated from the pure push/pull direction to generate aExpand

Remote vibrotactile noise improves light touch sensation in stroke survivors’ fingertips via stochastic resonance
Background and purposeStroke rehabilitation does not often integrate both sensory and motor recovery. While subthreshold noise was shown to enhance sensory signal detection at the site of noiseExpand

Investigating the Role of Vibrotactile Noise in Early Response to Perturbation
Timely reaction to perturbation is important in activities of daily living. Modulation of reaction time to and early recovery from perturbation via vibrotactile noise was investigated. It wasExpand
