ABSTRACT Objective To investigate if electrical stimulation through Russian current is able to maintain morphology of the cranial tibial muscle of experimentally denervated rats. Methods Thirty-six Wistar rats were divided into four groups: the Initial Control Group, Final Control Group, Experimental...

Abstract Background and objectives: The quadratus lumborum blockade was described by R. Blanco in its two approaches (I and II). The local anesthetic deposition in this location can provide blockade to T6-L1 dermatomes. We performed this fascia blockade guided by ultrasound for treating a chronic neurop...
Summary Objective: The aim was to evaluate the effectiveness of the experimental synergists muscle ablation model to promote muscle hypertrophy, determine the period of greatest hypertrophy and its influence on muscle fiber types and determine differences in bilateral and unilateral removal to reduce th...
ABSTRACT PURPOSE: To evaluate a new model of intraoperative electromyographic (EMG) assessment of the tibial and fibular nerves, and its respectives motor units in rats. METHODS: Eight Wistar rats underwent intraoperative EMG on both hind limbs at two different moments: week 0 and week 12. Supramaxima...
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgi...

Both biceps brachii muscle anatomical variations and the presence of communicating branches between the musculocutaneous nerve and the median nerve are common, and have clinical significance due to their connections and vulnerability. A case found during a routine dissection of the upper limb of a male c...
Piriformis muscle syndrome has been increasingly recognized as a cause of leg pain. Overuse, strain, or anatomical variations of the relationship between the nerve and the piriformis muscle are thought to be the underlying causes of the entrapment of the sciatic nerve. We report a variation not previousl...
In order to explore the change rule of myoblast stem cells (satellite cells, SCs) in the denervated and re-innervated muscle and to investigate the cellular mechanism of the morphological and functional changes of the muscle, denervated muscle atrophy and nerve regeneration models were established in one...
Among the sequelae of central nervous system injury is spasticity which is difficult to manage in rehabilitation. Current treatments consider the administration of the botulinum toxin. However, results have proved highly variable in terms of effectiveness, attributable to the distance between the injecti...
During the laboratory dissection of the brachial region and the arm, an abnormal relation of median nerve with the accessory head of biceps brachii muscle has been observed unilaterally on the right upper limb of a male cadaver. Whereas the short and long heads have their normal origin, additional-excess...
