HD, a rare disease affecting young men in the second to third decades of life, is characterised by insidious onset and slowly progressive course followed few years later by static phase of unilateral or asymmetric atrophy of the hand(s) and forearm(s) with sparing of the brachioradialis characterised as oblique amyotrophy.
The radial nerve, originating from the C5-T1 root of the spinal cord and the posterior cord of the brachial plexus, innervates the brachioradialis, extensor carpi radialis longus, and brevis muscles and, then, divides into superficial and deep branches at the level of the forearm.
Although the FMG sensor was designed to monitor the muscles responsible for finger and wrist movements, structures related to the elbow flexion and forearm pronation, such as the brachioradialis and the pronator teres, respectively, also produce mechanical stimuli due their activation [29], affecting the magnitude and range of the FMG signals related to specific hand poses.
Painful mechanical pressure increased corticomotor excitability of the brachioradialis muscle [34].
It is generally thought that functional limitations following a proximal biceps rupture are relatively minimal, due to the work of other flexors and supinators, including the brachialis and brachioradialis. However, because strength and endurance of the muscle can decrease by about 25%, physical laborers and high-demand athletes may notice a degree of residual weakness with supination and elbow flexion.
Areflexia was detected in biceps, patellar and Achillian deep tendon reflexes bilaterally and hypoactive in brachioradialis and triceps muscles; bilateral plantar flexor responses were observed.
The biceps, triceps, and brachioradialis muscle stretch reflexes were present and equal in BUE.
Underneath that is a muscle called brachialis, and then there's a third muscle called brachioradialis that kind of helps with elbow flexion.
Scores for several muscles that contribute to elbow movement (left brachialis, left brachioradialis, right brachioradialis) were also significantly higher in the Third Intermediate/Napatan sample.
Two schanz pins were passed proximally in the middle third radius between brachioradialis and ECRB and two distally in the 2nd metacarpal, for radiocarpal distraction.
The patient's neurological assessment was significant only for hyperreflexia of the left upper limb (+3 for left brachioradialis, biceps, and triceps reflexes).
The biceps brachii and brachioradialis are essential muscles that are frequently used in activities of daily living such as eating, dressing, and opening a door [3].
