Objectives of this paper were to elucidate key factors of hip circle forward on horizontal bar from electromyographic point of view. Subjects employed in the experiments were 7 healthy male adults, ranging from skilled subjects to non-skilled. Electromyograms (EMGs) were recorded by conventional method using surface electrodes from the flexor carpi radialis, the extensor carpi radialis brevis, ...

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 ...

Forelimb trajectory and the activity of eight muscles operating at the elbow, wrist and digit joints were analyzed during contact placing (CP) reactions elicited by tactile stimuli applied to the lateral (L) or medial (M) side of the cat's forepaw to verify whether a common movement strategy was used in these reactions. A tactile stimulus applied to the lateral side of the paw led, most frequen...

Lateral epicondylitis, commonly referred to as tennis elbow, affects 1% to 3% of the population.1 It is thought to be an overuse injury, originating in the wrist extensor muscles, rather than an inflammatory problem. It is brought on by occupational activities and sports that involve a repetitive wrist motion or a power grip. The condition is most commonly associated with workrelated activities...

[Medical Research Council (MRC) 2–3] was detected in the triceps brachii, f lexor carpi ulnaris and median nerve-innervated hand muscles. The flexor carpi radialis and ulnaris, extensor carpi ulnaris and finger flexors were mildly impaired. The shoulder girdle muscles, the biceps brachii, brachioradialis and extensor carpi radialis were spared. The muscle stretch reflexes were normal, except fo...

The purpose was to evaluate the interexaminer reliability of experienced and inexperienced examiners on location and classification of myofascial trigger points (MTrPs) in two epicondylar muscles and the association between the MTrP found and the diagnosis of lateral epicondylalgia (LE). Fifty-two pianists (some suffered LE) voluntarily participated in the study. Three physiotherapists (one ine...

Repetitive valgus stress of the elbow can result in excessive strain or rupture of the native medial ulnar collateral ligament (MUCL). The flexor-pronator mass (FPM) may be particularly important for elbow valgus stability in overhead-throwing athletes. The aim of this study was to identify the relative contribution of each muscle of the FPM--that is, the flexor carpi ulnaris (FCU), flexor digi...

Our knowledge about the mechanisms of human motor cortex facilitation induced by repetitive transcranial magnetic stimulation (rTMS) is still incomplete. Here we used pharmacological conditioning with carbamazepine, dextrometorphan, lorazepam, and placebo to elucidate the type of plasticity underlying this facilitation, and to probe if mechanisms reminiscent of long-term potentiation are involv...

The objective of this study was to investigate the significance of pulse configurations and current direction for corticospinal activation using transcranial magnetic stimulation (TMS). In 11 healthy subjects (8 female), a motor map for the motor evoked potentials (MEPs) recorded from the first dorsal interosseus (FDI), abductor digiti minimi (ADM), extensor carpi radialis, and biceps brachii (...
