We investigated the electromyographic response to synchronous indirect-localized vibration interventions in international and national table tennis players. Twenty-six male table tennis players, in a standing position, underwent firstly an upper arms maximal voluntary contraction and thereafter two different 30-s vibration interventions in random order: high acceleration load (peak acceleration...

Objective: “Cheiralgia paresthetica” is the term suggested by Wartenberg in 1932, to define isolated neuropathy of the superficial branch of the radial nerve (SRN). Radial nerve compression can occur throughout its course in the forearm, especially in the tunnel region beneath the tendon of the brachioradialis muscle. The authors report three cases with review of the literatures. Methods: The a...

Since its original description by Keizo Hirayama in 1959, "juvenile muscular atrophy of the unilateral upper extremity" has been described under many nomenclatures from the east. Hirayama disease (HD), also interchangeably referred to as monomelic amyotrophy, has been more frequently recognised in the west only in the last two decades. HD presents in adolescence and young adulthood with insidio...

BACKGROUND The use of the mechanomyogram (MMG) which detects muscular vibrations generated by fused individual fiber twitches has been refined. The study addresses a comparison of the MMG and surface electromyogram (SEMG) in monitoring muscle fatigue. METHODS The SEMG and MMG were recorded simultaneously from the same territory of motor units in two muscles (Biceps, Brachioradialis) of the hu...

BACKGROUND Precise and accurate field methods for body composition analyses in athletes are needed urgently. AIM Standardisation of a novel ultrasound (US) technique for accurate and reliable measurement of subcutaneous adipose tissue (SAT). METHODS Three observers captured US images of uncompressed SAT in 12 athletes and applied a semiautomatic evaluation algorithm for multiple SAT measure...

Anterior interosseous nerve syndrome (Kiloh-Nevin Syndrome) is the triad of weakness of the flexor pollicis longus, the flexor digitorum profundus of the index finger, and the pronator quadratus. It is a manifestation of neuropathy affecting either the anterior interosseous nerve itself (anterior interosseous neuropathy) or its fascicles more proximally within the median nerve or brachial plexu...

The purported ergogenic actions of transcranial direct current stimulation (tDCS) applied to motor cortex (M1) on force production and perception of effort were investigated using a 10-item numerical rating scale (0-10 NRS) in nonfatiguing bouts of a force-matching task utilizing isometric elbow flexion. Using a crossover design, 12 healthy volunteers received sham, anodal, and cathodal tDCS ra...

Thirteen patients were operated on for hand palsies in cases of C7 to T1 or C8, T1 root avulsions. Finger flexion and intrinsic function were paralyzed in all patients. Finger extension was paralyzed in 12 patients. Wrist flexion and extension were present in all patients. Tendon transfers were performed to restore the different functions. The extensor carpi radialis longus was transferred to t...

This study proposes the implementation of an algorithm allowing one to derive absolute blood root-mean-square (RMS) velocity values from laser Doppler perfusion meter (LDP) data. The algorithm is based on the quasi-elastic light scattering theory and holds for multiple scattering. While standard LDP measurements are normally applicable to a small region of interest (approximately 1 mm2), the pr...

A case of anomalous terminal branching of the axillary artery, concerning the variant called superficial brachioradial artery (arteria brachioradialis superficialis) was described, with special regard to its embryological origin. The left upper limb of a male cadaver was dissected in successive steps from the axillary fossa distally to the palmar region. A variant artery, stemming from the end ...
