Total Knee Arthroplasty (TKA) proposed as an alternative treatment for damaged knee joints of humans is reviewed. The commercial application TKA can help patients to improve their daily normal activities. Here the high-flex type total arthroplasty (High-Flex TKA) typically designed patient’s convenience on which greater range motion be adjusted extreme activities such Seiza and Muslim praying. ...

Adequate knee flexion velocity at toe-off is important for achieving normal swing-phase knee flexion during gait. Consequently, insufficient knee flexion velocity at toe-off can contribute to stiff-knee gait, a movement abnormality in which swing-phase knee flexion is diminished. This work aims to identify the muscles that contribute to knee flexion velocity during double support in normal gait...

This study evaluated the influence of intra-operative soft tissue balance on post-operative range of motion in patients undergoing posterior-stabilized total knee arthroplasty with navigation. After implantation of all components in 31 consecutive patients, the joint component gap was measured manually with the knee at 0°, 90°, and 120° as guided by a navigation system. We designated soft tissu...

The current study analyzed changes in anterior cruciate ligament (ACL) and lateral collateral ligament stress as a result of mechanical varus. In an exploratory pilot study, progressive mechanical varus was introduced to a male finite element model of the lower limb at different knee flexion angles. Nine situations were analyzed (combinations of 0°, 30°, and 60° knee flexion and 0°, 5°, and 10°...

The brachialis muscle (BR) represents an important elbow flexor and its activity has so far mainly been measured with intramuscular electromyography (EMG). The aim of this study was to examine whether the activity of the BR can be assessed with surface EMG without interference from the biceps brachii (BB). With eight subjects we measured surface EMG of the arm flexor synergists, BR, BB, and bra...

[Purpose] This study investigated the flexion-relaxation phenomenon of the erector spinae in elderly women with chronic knee osteoarthritis and determined whether the flexion-relaxation phenomenon can be used as a pain evaluation tool in such cases. [Subjects and Methods] Seventeen elderly females with chronic knee osteoarthritis and 13 healthy young females voluntarily participated in this stu...

Muscle contracture and joint stiffness are a major concern during limb lengthening using the Ilizarov method. The aim of this study was to detect factors that may influence the final loss of knee flexion. We retrospectively studied knee movement in 32 patients undergoing femoral lengthening using the Ilizarov method. The pattern of loss of knee movement showed a rapid fall in knee flexion durin...

For effective rehabilitation of the shoulder, physical therapists must have correct knowledge of shoulder motion. Reports conflict on whether medial or lateral rotation of the humerus accompanies shoulder flexion. The purpose of this study was to determine the relationship between flexion and rotation at the glenohumeral joint. We determined rotation that accompanied active shoulder flexion by ...

1. In the rock lobster, Palinurus vulgaris, study was made of the effect of active flexion of the J3 joint of the flagellum upon the reflex produced by passive movement of this joint. 2. Active flexion was accompanied by activity of motoneurones to musdes assisting the movement. 3. Passive flexion not immediately preceded by active flexion was accompanied by activation of muscles to resist the ...

We prospectively examined the relationship between preand postoperative range of motion utilizing three cruciate retaining knees with various mechanical flexion potential, i.e., two at about 130–135 degrees (one with a bearing having a posterior lip and the other without) and the third at about 140–145 degrees. Combining data from the three cohorts, patients with the following preoperative flex...
