background due to the fundamental role of gripping in most upper limb activities, grip strength promotion is a chief goal in the treatment of patients with upper limb musculoskeletal disorders. kinesio taping is a novel and effective therapeutic technique believed to facilitate muscle contraction through stimulating mechanoreceptors and increasing the sensory feedback around the taped region. o...

Repetitive, high-force pinch grip exertions are common in many occupational activities. The goal of the current study was to quantify the relationship between lateral pinch grip span (distance between thumb and index finger) and lateral pinch grip strength. An experiment was conducted in which 40 participants performed maximal lateral pinch grip exertions at 11 levels of grip span distances (0,...

Purpose: Muscle activation of the proximal parts is necessary for distal activities. In fact, proximal muscles provide stabilized and controlled base for distal parts activities. The purpose of this systematic review was to determine whether hand grip task can alert the activation of shoulder girdle muscles. Methods: A literature search was done in PubMed, Scopus, Elsevier, Ovid, CINAHL, S...

Grip kinetics and their variation are emerging as important considerations in the clinical assessment of handwriting pathologies, fine motor rehabilitation, biometrics, forensics and ergonomic pen design. This study evaluated the intra- and inter-participant variability of grip shape kinetics in adults during signature writing. Twenty (20) adult participants wrote on a digitizing tablet using a...

INTRODUCTION Healthy subjects scale grip force to match the load defined by physical object properties such as weight, or dynamic properties such as inertia. Patients with Parkinson's disease (PD) show an elevated grip force in dynamic object handling, but temporal aspects of anticipatory grip force control are relatively preserved. In PD patients, beta frequency oscillatory activity in the bas...

INTRODUCTION To evaluate the impact of needle driver design on laparoscopic suturing skills by experts and novices. METHODS Three experienced laparoscopic surgeons and 3 novice junior residents were asked to perform a fixed set of suturing tasks in a laparoscopic pelvic-trainer. The laparoscopic needle drivers compared were (1) the Ethicon driver (E 705R), (2) Karl Storz (KS) pistol grip (261...

While task-dependent changes in motor cortical outputs have been previously reported, the issue of whether such changes are specific for complex hand tasks remains unresolved. The aim of the present study was to determine whether cortical inhibitory tone and cortical output were greater during precision grip and power grip. Motor cortex excitability was undertaken by using the transcranial magn...

Musculoskeletal Disorders (MSDs), especially those of the upper limb are a common concern in modern industry, and physical risk factors such as force and posture are linked to their causation. The effects of the combination of forceful gripping or grasping (especially pinch grips) and awkward postures should be considered in the causation of MSDs. Current guidelines recommend that wherever poss...
