Intraoperative sarcomere length measurements reveal differential design of human wrist extensor muscles.
The design of the wrist extensor muscles was studied using a combination of intraoperative laser diffraction and biomechanical modelling of data obtained from human patients and previously published data. Intraoperatively, the change in sarcomere length per degree joint angle rotation (i.e. dSL/d omega) was measured as the wrist was moved from neutral to full flexion in both the extensor carpi ...
متن کاملThe application of an external wrist extension force reduces electromyographic activity of wrist extensor muscles during gripping.
STUDY DESIGN Experimental repeated-measures study. OBJECTIVE To investigate the effect of different extension forces applied to the palm of the hand on electromyographic (EMG) activity of the wrist extensor muscles during hand gripping. BACKGROUND Lateral epicondylitis is usually caused by repetitive wrist extension that leads to an overuse injury. The current theory is that the process of ...
متن کاملBiomechanical Analysis of Force Distribution in Human Finger Extensor Mechanisms
The complexities of the function and structure of human fingers have long been recognised. The in vivo forces in the human finger tendon network during different activities are critical information for clinical diagnosis, surgical treatment, prosthetic finger design, and biomimetic hand development. In this study, we propose a novel method for in vivo force estimation for the finger tendon netw...
متن کاملProximal wrist extensor tendinopathy
Proximal wrist extensor tendinopathy, which is also known as tennis elbow, is pain at or just distal to the lateral humeral epicondyle within the proximal wrist extensor tendon. It occurs commonly in certain athletes but can also occur in people with jobs that require repetitive movements of the hand and upper limb. In most cases the tendon involved shows no signs of inflammation or tendonitis,...
متن کاملAnatomical Variation of Radial Wrist Extensor Muscles: A Study in Cadavers
OBJECTIVE The tendons of the extensor carpi radialis longus and brevis muscles are quite useful in tendon transfer, such as in correction of finger clawing and restoration of thumb opposition. Knowledge of additional radial wrist extensor muscle bellies with independent tendons is useful in the above-mentioned surgical procedures. METHODS The skin, subcutaneous tissue, and antebrachial fascia...
