Brain control of prehension is thought to rely on two specific brain circuits: a dorsomedial one (involving the areas of the superior parietal lobule and the dorsal premotor cortex) involved in the transport of the hand toward the object and a dorsolateral one (involving the inferior parietal lobule and the ventral premotor cortex) dealing with the preshaping of the hand according to the featur...

Hand exercise is recommended for hand osteoarthritis (OA) management, but few efficacy studies have been published. The purpose of the study was to determine the effects of two years of whole body strength training and gripper exercise on hand strength, pain, and function in adults with radiographic evidence of hand OA. Older adults (N=55; 71.5+/-6.5 years; 80% female) participated in a two-yea...

BACKGROUND This study aimed to examine the relationship between hand-grip force and maximum inspiratory pressure (PImax) in healthy young and middle-age individuals. METHODS All individuals underwent assessment of inspiratory muscle strength by maximum inspiratory pressure using a U-type water manometer and evaluation of hand-grip force by a hydraulic hand dynamometer. RESULTS The correlati...

OBJECTIVE A commonly adhered to operating principle in occupational therapy clinics is that a person must exhibit 20 lb of grip strength before his or her hand is considered "functional." This study examined the relationship between hand and finger grip performances with the forces required to open common household containers. METHOD The grip and pinch strengths of 49 college students were ob...

Background: Hand dexterity a measure of hand flexibility and coordination can be affected by many factorsincluding grip strength. However, there are limited studies data about the association between handdexterity strength in Asian population. Hence, we aim to investigate relationship healthy males aged 18 25 years old population.Methods: Fiftyhealthy adult male participants 18-25 were recruite...

Although hand grip strength is critical to the daily lives of humans and our arboreal great ape relatives, human has changed in form function throughout evolution due terrestrial bipedalism, tool use, directional asymmetry (DA) such as handedness. Here we investigate how interact modern gain an insight into evolutionary past. We measured a heterogeneous, cross-sectional sample participants (n =...

When moving objects with a precision grip, fingertip forces normal to the object surface (grip force) change in parallel with forces tangential to the object (load force). We investigated whether voluntary wrist actions can affect grip force independent of load force, because the extrinsic finger muscles cross the wrist. Grip force increased with wrist angular speed during wrist motion in the h...

The hemodynamic responses to isometric exercise (hand grip) were investigated in normotensive subjects during a 150 mEq (n = 8) sodium diet and a 10 mEq (n = 6) sodium diet both before and after the administration of the converting enzyme inhibitor teprotide. Although teprotide significantly decreased the mean arterial pressure during both sodium intakes, the normal pattern of hemodynamic respo...

OBJECTIVE To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. METHODS We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects use...
