Arterial entrapment syndrome (AES) at elbow level is very rare and to our knowledge no case of AES by lacertus fibrosus in the cubital fossa in presence of brachial artery duplication has been described to date. We describe a rare case of acute arterial thrombosis of one of two brachial arteries highlighted in the cubital fossa which developed after strenuous right elbow flexor muscle activity ...

Previous studies have shown modulation of corticospinal output of the agonist muscle when a known-movement is prepared but withheld until a response signal appearance, reflecting motor preparation processes. However, modulation in the antagonist muscles has not been described, despite the fact that reaching movements require precise coordination between the activation of agonist and antagonist ...

background: exercise is a widely prescribed treatment for chronic low back pain. the purpose of the present study was to investigate the effect of 8 weeks exercise on pain, disability and endurance of trunk flexor-extensor muscles in female with chronic idiopathic low back pain. methods: this clinical trial study has been done on 12 patients who referred to the arak city clinics. the function o...

Abstract Introduction Improved outcome measures of muscle reinnervation would facilitate clinical translation new therapies which hope to enhance human peripheral nerve repair. Valid should be receptive the biological process and correlate with assessments muscular function. This study investigated responsiveness volumetric MRI its relationship indices Method Twenty-five patients who underwent ...

The consistency and the number of attempts required to achieve maximal voluntary muscle activation have not been documented and compared between young and old adults. Furthermore, few studies have contrasted activation between functional pairs of muscle groups, and no study has tested upper limb muscles. The purpose of this study was to measure and compare voluntary muscle activation of the elb...

Background & Aims: Forward head posture deformity is a disorder in head weight balance condition leading to some alterations in cervical muscles, strength. This research aimed to determine the strength of deep and superficial cervical flexor muscles in female students with forward head posture compared to the normal group. Methods: From the total of 724 female students in Shahid Bahonar Univers...

8.1.1 The Modeling Challenge: Keeping the Goal in Mind It is doubtful that anyone would argue that biological motor control systems are less complex than robots. Given that modeling and designing robotic control systems that can walk or manipulate objects is quite challenging to engineers [e.g. (Lee, 1989)], is there any hope for those of us who wish to develop "adequate" models of biological m...

The purpose of this study was to use paired-pulse transcranial magnetic stimulation (TMS) to examine the effect of eccentric exercise on short-interval intracortical inhibition (SICI) after damage to elbow flexor muscles. Nine young (22.5 ± 0.6 yr; mean ± SD) male subjects performed maximal eccentric exercise of the elbow flexor muscles until maximal voluntary contraction (MVC) force was reduce...

Exercise performance is impaired by increased respiratory work, yet the mechanism for this is unclear. This experiment assessed whether neural drive to an exercising muscle was affected by cortically driven increases in ventilation. On each of 5 days, eight subjects completed a 2-min maximal voluntary contraction (MVC) of the elbow flexor muscles, followed by 4 min of recovery, while transcrani...
