Lateral epicondylitis, commonly referred to as tennis elbow, is a syndrome characterized by pain over the origin of the common extensor muscles of the fingers, hand and wrist at the lateral epicondyle. Reports of 70-90% response to conservative treatment at one year have been documented in the literature though refractory cases often require surgical management. Arthroscopic treatment of latera...

We report the case of a 40-year-old woman with pseudoachondroplasia (PSACH), with a heterozygous mutation (c.806A > G, p.Asp269Gly) located in the Type 3 repeats domain of the cartilage oligomeric matrix protein gene, who complained of the unusual symptom of painful locking of the wrist. Her condition was caused by a non-traumatic enlargement of the extensor carpi radialis longus (ECRL) and bre...

Tendon transfers to the extensor carpi radialis brevis (ECRB) are often performed to augment wrist extension. This study was conducted to analyze how transfer of the extensor carpi ulnaris (ECU) to the ECRB affects the moment arms, force-generating capacity, and moment-generating capacity of the ECU over a range of wrist flexion-extension. A graphics-based computer model was developed from anat...

Background: Enthesopathy of the extensor carpi radialis brevis origin [eECRB] is a common idiopathic, noninflammatorydisease of middle age that is characterized by excess glycosaminoglycan production and frequentlyassociated with radiographic calcification of its origin. The purpose of our study was to assess the relationship ofcalcification of the ECRB and advancing age.<br /...

OBJECTIVE This study assessed the muscular activity during root canal preparation through kinematics, kinetics, and electromyography (EMG). MATERIAL AND METHODS The operators prepared one canal with RaCe rotary instruments and another with Flexo-files. The kinematics of the major joints was reconstructed using an optoelectronic system and electromyographic responses of the flexor carpi radial...

The purpose of this study was to evaluate the delayed effects of repetitive sensory stimulation with passive wrist movement on corticospinal excitability of the forearm and hand musculature. Motor evoked potential responses to single and double pulse transcranial magnetic stimulation were recorded from the flexor carpi radialis, extensor carpi radialis, and the first dorsal interosseous muscles...

BACKGROUND The optimal surgical treatment for Kienböck's disease with stages IIIB and IV remains controversial. A cadaver study was carried out to evaluate the use of coiled extensor carpi radialis longus tendon for tendon interposition and a strip obtained from the same tendon for ligament reconstruction in the late stages of Kienböck's disease. METHODS Coiled extensor carpi radialis longus ...

BACKGROUND INFORMATION The present study aimed to investigate the effects of Kinesio Taping on the trajectory of the forelimb and the muscle activity of the M. brachiocephalicus and the M. extensor carpi radialis in horses. 19 horses and ponies of different breeds (body weight: 496±117 kg), gender (8 mares, 10 geldings and 3 stallions) and ages (14.9±6.9 years old) were analysed without Kinesio...

BACKGROUND: Muscle fatigue can be defined as the failure of a muscle to maintain a reasonably expected force output. The multivariate approach to fatigue assessment is used because the multiple (EMG) feature provides more information than anyone. OBJECTIVE: This study presents a method of assessing muscle fatigue during endurance testing at 50% maximal voluntary contraction (MVC) using electro...
