Repeated discharges with doublets and triplets were observed without fibrillations, positive sharp waves (PSWs) and myotonia along with normal recruitment pattern gastrosoleus, anterior tibialis, abductor pollicis brevis, first dorsal interossei, brachioradialis bilateral.
The muscles sampled were extensor indicis proprius, extensor digitorum communis, brachioradialis, triceps brachii, deltoid, flexor carpi radialis, pronator teres, flexor pollicis longus, and cervical paraspinals.
Nerve conduction study showed left ulnar compression mononeuropathy at the elbow of moderate severity as well as mild left-sided carpal tunnel syndrome with no evidence of left-sided C5-T1 radiculopathy Electromyography (EMG) showed no evidence of myopathy (including inflammatory myopathy) in the left deltoid, biceps, brachioradialis, extensor indicis muscle, extensor digitorum muscle, flexor digitorum profundus, adductor pollicis brevis, right deltoid, right rectus femoris, and iliopsoas muscle.
Deep tendon reflexes 2+ and symmetric at the biceps, triceps, brachioradialis; 3+ at patellas and ankles bilaterally.
EMG of C5, C6 myotomes namely deltoid, biceps brachii and brachioradialis was normal.
MRI of the right forearm mass showed a well-defined, lobulated, heterogeneous mass with high signal intensity on T2WI and a strong heterogeneous enhanced mass at the brachioradialis muscle.
Therefore, in cases where other nerves are included in the flap, embedment of the proximal segment of the nerve in the donor site in the brachioradialis muscle was recommended.
The etiology of the isolated superficial radial nerve neuropathy is often associated with repeated use of wrist watches, falling, forearm fractures, surgical operations such as fracture fixation and arthroscopic procedures, steroid injections, acupuncture, use of handcuffs, repetitive supination, pronation, ulnar flexion activities, compression of extensor carpi radialis and/or brachioradialis tendons, presence of neuroma, lipoma or ganglion cyst in the wrist as well as exposure to excess cold.
They were subcutaneously tunneled to the following target muscles: adductor pollicis (AP), abductor pollicis longus (APL), flexor digitorum profundus (FDP), and extensor digitorum communis (EDC) for hand muscles; flexor carpi ulnaris (FCU), and extensor carpi radialis (ECR) for wrist muscles; brachioradialis (BRA) and triceps lateral head (TRA) for elbow muscles; biceps long head (BIL) and triceps long head (TRO) for shoulder-elbow double joint muscles; and pectoralis major clavicular head (PECM) and deltoid clavicular part (DELP) for shoulder muscles.
reported the intersession reliability of maximal contraction of the elbow flexor group (BB, brachialis, and brachioradialis muscles) using sEMG.
Deltoid, biceps brachii, triceps brachii, and brachioradialis have more influences on the abnormal movement pattern.
