Simulation of Motion Trajectory for Rehabilitation of Finger Flexor Tendons and Extensor Digitorum Tendons
نویسنده
چکیده
Injury to finger flexor tendons or extensor digitorum tendons necessitates operations and rehabilitation to regain normal function. In this study, a system was designed to simulate the rehabilitation motions for injured finger flexor and extensor digitorum tendons, such as making a fist and extending the fingers. The dynamic system (DS) is based on a 16-segment hand model and was designed using Lagrange-Euler (LE) equations of motion for 27 degrees of freedom (DOF). The The minimum energy control (MEC) method was used to simulate the optimal motion trajectory (OMT) for finger rehabilitation. The simulation results showed that under the established boundary conditions (BC) for finger joint motions within a limited time, the designed algorithm can calculate the optimal motion trajectory for finger rehabilitation. Therefore, this algorithm can assist people in adjusting the rehabilitation motions of their injured finger flexor and extensor digitorum tendons. In addition, since this algorithm can calculate the velocity and moment for each segment of the hand, it can be applied to the design of finger rehabilitation equipment for controlling the motion trajectory (MT) of a certain segment.

Effect of Hyaluronic Acid in the Excursion Resistance of the Tendon Graft:a Biomechanical in Vitro Study in a Human Model
Introduction: Postoperative finger function after flexor tendon graft is occasionally unsatisfactory. Postoperative adhesion inhibits the restoration of excursion and strength of the grafted tendons. Hyaluronic acid (HA) is not only a lubricant but also a factor to prevent adhesion. The purpose of this study is to evaluate the changes of excursion resistance between potential graft donor source...

Introduction: The usual causes of flexor tendon injuries in hand are penetrating wounds. Closed injury and avulsion of flexor tendon are rare and mostly occur as avulsion of flexor digitorum profundus tendon of ring finger from its bony insertion at distal phalanx. Closed avulsion of flexor digitorum superficialis is even rarer. The rarest is simultaneous closed avulsion of both flexors in...

Background & Aims: Etiologically the causing factor of carpal tunnel syndrome is not clear and multiple contributing factors such as the presence or absence of Palmaris longus tendon have been cited. The aim of the present study was to compare patients with carpal tunnel syndrome and healthy individuals in regard to the absence and presence of Palmaris longus and fifth flexor digitarum superfic...

In C7 to T1 or C8, T1 root avulsion palsies, restoration of finger active extension is not possible. Only tenodesis may restore hand opening in active wrist flexion. Many techniques have been described to restore this motion. In routine techniques, extensor tendons are fixed on radius or sutured on dorsal retinaculum. However, in these procedures, progressive tendon lengthening or ruptures may ...
متن کاملAnomalous extensor tendons of hand: a case report with clinical importance
The extensor digitorum muscle of the hand originates from the common extensor origin i.e., from the lateral epicondyle of the humerus and ends in four tendons, one for each digit except for the thumb. This paper reports a case, in which the tendon of the extensor digitorum ended as four tendons to the index, middle, ring and little fingers, but displayed variations in the number of tendons to e...
