In many species of frog, the forelimb muscles important in amplexus are known to be much larger in males than in females. We studied this dimorphism in three forelimb muscles in the bullfrog [abductor indicus longus (AIL), flexor carpi radialis (FCR) and extensor carpi radialis (ECR)] by testing their isometric contractile properties. One muscle that is not dimorphic, the extensor carpi ulnaris...

Srijit Das I read with great interest the article entitled 'Anatomical variation of radial wrist extensor muscles: a study in cadavers' by Nayak et al., which was published in the 2008;63(1) issue of Clinics. 1 The article had meticulous descriptions of some of the variations in the extensor muscles. The authors highlighted the clinical importance of the anomalous muscle in tendon transfer. It ...

Background: The Extensor Carpi Radialis Longus (ECRL) and the Extensor Carpi Radialis Brevis (ECRB) are muscles of the posterior forearm compartment. variations in this area of the forearm are common and are usually diagnosed during surgery. Sometimes these variations are symptomatic and can be helpful in clinical procedures such as surgery. Diagnosis and identification of abnormalities can be ...

INTRODUCTION Adequate needling at LI11 (Quchi) can be achieved by perpendicular angulation of the needle so that the needle tip enters the extensor carpi radialis longus (ECRL) muscle, which corresponds to the dermatomes and myotomes of the fifth and sixth cervical spinal segments. Although indirect methods using modern technology can be used to examine the variable effects of different depths ...

This review describes a series of experiments in which sarcomere length was measured in human wrist muscles to understand their design. Sarcomere length measurements were combined with studies on cadaveric extremities to generate biomechanical models of human wrist function and to provide insights into the mechanism by which wrist strength balance is achieved. Intraoperative measurements of the...

Work-related musculoskeletal disorders (WRMSDs) in massage practitioners is prevalent due to physically demanding nature of practice. Given that changes techniques may occur over the course a day accommodate for fatigued muscles and use proper also be compromised with fatigue musculature upper extremity, research regarded effects different on muscular demands needed further explored. In this st...

background lesions in peripheral nerves are highly prevalent in the upper extremity. the present study compares different tendon transfer surgeries in patients with radial nerve palsy. methods fifty patients with radial nerve palsy were randomly selected among patients who referred to tehran 15th khordad hospital during 2006-2011. they were divided into two groups of 17 and 33 subjects. single ...
