A guided tendon concept in the context of rotating helicopter blades is proposed to modify their dynamic characteristics, so that rotorcraft can operate under a wide range working conditions. In this paper, pre-twisted beam with bending-bending-torsion coupling axially loaded by used model system. An internally attached at several spanwise locations avoid resonant vibrations due insufficient se...

Unlike the inverse kinematics problem of n-tendon continuum robots, forward lacks a closed-form analytical solution. In this paper, novel algorithm for single-segment flexible robots is developed that can determine resulting beam configuration any given set actuator displacements. The determines key parameters all possible n- to 1-tendon combinations and examines them against evaluation criteri...

We assessed 20 shoulders with rotator cuff tendinopathy and partial tendon tears treated with FIT® plasters (far infrared technology). The criteria for inclusion were pain at night and during active shoulder movement. Patients with restricted passive movement (adhesive capsulitis) and complete tendon tears were excluded. Two different types of FIT® plasters were used according to the different ...

BACKGROUND There has been no published report assessing the mechanical properties of a repaired Achilles tendon after surgery using shear wave elastography (SWE). The aim of this study was to investigate the changes in mechanical properties of the healing Achilles tendon after surgical repair of a tendon rupture using ultrasound SWE and how these changes correlate with tendon function. MATERIAL...

BACKGROUND The purpose of this investigation was to evaluate if clinical assessment, Ultrasound + Colour Doppler (US + CD) and Ultrasound Tissue Characterisation (UTC) can be useful in detecting plantaris tendon involvement in patients with midportion Achilles tendinopathy. METHODS Twenty-three tendons in 18 patients (14 men, mean age: 37 years and 4 women: 44 years) (5 patients with bilatera...

Abaamet The wound healing process of New Zealand rabbit extensor digitorum communis tendon was studied from the fifth through th&ecnth post-surgical day by concurrent observation of physical, mechanical, and biochemical properties. Me&an&l testing was by isometric thcrmic denaturation followed by biochemical assay of tendon and the physiological saline bathing medium for collagen protein and ac...

The objective of this study was to compare tissue Doppler imaging and speckle tracking ultrasound to assess the relative motion of flexor tendon and surrounding subsynovial connective tissue (SSCT). Twenty normal human wrists were imaged with an ultrasound scanner. The two ultrasound methods measured the excursion and maximum velocity of the tendon and SSCT while subjects gripped three differen...

BACKGROUND Chronic Achilles tendon tears could hinder patients and represent a challenge to surgeons. Although many different surgical techniques have been proposed for reconstruction of a neglected Achilles tendon rupture, there is no clear evidence to support one technique over the others, but the use of a technique that could allow for an "anatomical" reconstructions seems desirable. METHO...

Active Achilles tendon kinesitherapy facilitates the functional recovery of a ruptured Achilles tendon. However, protein expression during the healing process remains a controversial issue. New Zealand rabbits, aged 14 weeks, underwent tenotomy followed immediately by Achilles tendon microsurgery to repair the Achilles tendon rupture. The tendon was then immobilized or subjected to postoperativ...
