Introduction Sustained, repetitive, prehensile activities that require precision and stability, necessitate a sustained static shoulder girdle posture over long periods of time, which can result in abnormal activation the musculature consequent scapular misalignments. Aim, Aim this study was to establish test-retest inter-tester reliability six (6) clinical tests commonly used measure parameter...

Seahorses (Genus Hippocampus; Family Syngnathidae) are iconic fish characterised by tails with prehensile capabilities, which develop after the transition from planktonic to benthonic lifestyle. As a result, seahorses remain attached vegetal structures or other elements most of time, both in wild and under rearing conditions. In present simulation study, we assessed effect artificial holdfast o...

The European leaf toed Gecko, Euleptes europaea , is a strictly nocturnal species endemic to the western Mediterranean and has long been considered rock-specialist as it associated with this habitat during its entire daily life cycle. In study, we report observations of arboreal behaviour in E. collected field research over 40-year period from across range. We provide review available informati...

The biogeography of islands is often strongly influenced by prior geological events. Corucia zebrata (Squamata: Scincidae) is endemic to the geologically complex Solomon Archipelago in Northern Melanesia. We examined the level of divergence for different island populations of C. zebrata and discussed these patterns in light of Pleistocene land bridges, island isolation, and island age. Corucia ...

Consistent evidence suggests that the way we reach and grasp an object is modulated not only by object properties (e.g., size, shape, texture, fragility and weight), but also by the types of intention driving the action, among which the intention to interact with another agent (i.e., social intention). Action observation studies ascribe the neural substrate of this 'intentional' component to th...

A kinematic model has been developed for simulation and prediction of the prehensile capabilities of the human hand. The kinematic skeleton of the hand is characterized by ideal joints and simple segments. Finger-joint angulation is characterized by yaw (abduction-adduction), pitch (flexion-extension) and roll (axial rotation) angles. The model is based on an algorithm that determines contact b...

We introduce a reconfigurable underactuated robot hand able to perform systematic prehensile in-hand manipulations regardless of object size or shape. The utilizes two-degree-of-freedom five-bar linkage as the palm gripper, with three three-phalanx fingers, jointly controlled by single actuator, connected mobile revolute joints palm. Three actuators are used in system total, one for controlling...

Programmable vector elds are an abstraction to represent a new class of devices for distributed, non-prehensile manipulation for applications in parts feeding, sorting, positioning, and assembly. Unlike robot grippers, conveyor belts, or vibratory bowl feeders, these devices generate force vector elds in which the parts move until they may reach a stable equilibrium pose. Recent research in the...
