The metabolic activity of tendinous tissues has traditionally been considered to be of limited magnitude. However, recent studies have suggested that glucose uptake increases in the force-transmitting tissues as a response to contractile loading, which in turn indicates an elevated tissue metabolism. The purpose of the present study was to investigate whether such a mechanism could be observed ...

BACKGROUND Tendon is an integral part of joint movement and stability, as it functions to transmit load from muscle to bone. It has an anisotropic, fibrous hierarchical structure that is generally loaded in the direction of its fibers/fascicles. Internal load distributions are altered when joint motion rotates an insertion site or when local damage disrupts fibers/fascicles, potentially causing...

The authors report a case of a 47-year-old professional driver with an acute, simultaneous tear of patellar tendon and anterior cruciate ligament (ACL). The patient was treated in two stages. Acute patellar tendon repair and delayed (6-month postinjury) ACL reconstruction was performed. The authors discuss the possible mechanism of injury and the rationality of the two-stage surgical treatment.

Achilles tendon ruptures and malleol fractures are commonly seen injuries in orthopaedic and traumatology practice, but what is rare is their concomitant. In this report, we aimed to present a rare case of a patient who has isolated medial malleolar fracture and achilles tendon rupture in ipsilateral ankle after an ankle sprain due to a fall from stairs and mechanism of injury.

Over the past several years, there has been a rapidly expanding interest in the the study and construction o,f a new class of robot manipulators which utilize high degree of freedom, or continuous, backbone structures. I n this paper, we consider and illustrate some basic properties of a class of “hyper-redundant” robots, known as “continuum” robots. W e base our analysis around remotely-driven...

A high degree of freedom (DOF) benefits manipulators by presenting various postures when reaching a target. Using tendon-driven system with an underactuated structure can provide flexibility and weight reduction to such manipulators. The design control composite are challenging owing its complicated architecture modeling difficulties. In our previous study, we developed tendon-driven, high-DOF ...

Background Posterior tibial tendon dysfunction (PTTD) is a progressive and debilitating condition. Flat foot is a known associated factor of PTTD but there are still many questions about the biomechanical etiology of PTTD. Hypermobility in the first ray and first metatarsophalangeal joint (MPJ) is thought to be a causative factor in various foot pathologies including PTTD, however the associati...

Abstract This paper presents the design, analysis, and development of an anthropomorphic robotic hand coined MCR-hand II. takes advantages both tendon-driven linkage-driven systems, leading to a compact mechanical structure that aims imitate mobility human hand. Based on investigation anatomical related existing hands, design II is presented. Then, using D-H convention, kinematics this formulat...

Tendons are composed of longitudinally aligned collagen fibrils arranged in bundles with an undulating pattern, called crimp. The crimp structure is established during embryonic development and plays a vital role in the mechanical behaviour of tendon, acting as a shock-absorber during loading. However, the mechanism of crimp formation is unknown, partly because of the difficulties of studying t...

This paper introduces a novel kinematic model for tendon-driven compliant torso mechanism humanoid robots, which describes the complex behaviour of system characterised by interaction element with rigid bodies and actuation tendons. Inspired human spine, proposed is based on flexible backbone whose shape controlled two pairs antagonistic First, structure analysed to identify main modes motion. ...
