Flexor carpi radialis muscle atrophy due to cervical spondylotic amyotrophy.

Key Clinical Message: Presenting a rare case of flexor carpi radialis atrophy secondary to cervical spondylotic amyotrophy.

Abstract: A 52-year-old man with a history of cervicobrachial neuralgia presented with an advanced atrophy of the right flexor carpi radialis muscle with a groove hollowed out on the anterior surface of the right forearm. The spine MRI showed that this rare atrophy was related to a cervical spondylotic amyotrophy.

Flexor Carpi Radialis Muscle: Anatomic Features and Electromyography Technique Under Ultrasound Control.

The electromyographic assessment of the flexor carpi radialis muscle (FCRM) in the context of an upper limb extensors' deficiency helps physicians in differentiating radial nerve damage from C7 radicular impairment. Ultrasound (US)-guided electromyography (EMG) is mandatory to locate this muscle, particularly in the case of muscle atrophy, denervation, and neuromuscular disorders. The aim of this manuscript is to illustrate the anatomical specific features of the FCRM and the technical procedure of FCRM EMG with US guidance.

Importance of Anatomic Peculiarities and Ultrasound-Guided Electromyography of the Extensor Indicis Proprius Muscle.

The extensor indicis proprius muscle (EIPM) is considered a key muscle in the assessment of the level of the neurologic lesion causing any motor or sensory medio-cubital impairment of the hand. The aim of this study is to illustrate the anatomical peculiarities of the EIPM, the ultrasound (US) anatomy of the inferoposterior part of the forearm, and the technique of US-guided electromyography (EMG) of the EIPM. The US-guided EMG of the EIPM is technically easy and safe for young practitioners, provided there is a good knowledge of US anatomy of the inferoposterior part of the forearm.

Clinical Significance of Anatomic Peculiarities and Ultrasound-Guided Electromyography of the Posterior Tibial Muscle.

The posterior tibial muscle (PTM) is a key muscle in diagnosing the level of the neurologic lesion that causes steppage gate that is a paralysis of nervous origin of the muscles ensuring the foot dorsiflexion. The aim of this manuscript is to illustrate the anatomical peculiarities of the PTM, the ultrasound (US) anatomy of the infero-posterior part of the leg, and the technique of US-guided electro-neuro-myography (ENMG) of the PTM, which is considered a key muscle in the diagnosis of the neurological lesion causing steppage gate. The US-guided ENMG of the PTM is technically easy and safe for young practitioners provided there is a good knowledge of US anatomy of the infero-posterior part of the leg.

Efficacy of botulinum toxin A for the treatment of hemiparesis in adults with chronic upper limb spasticity.

Introduction: this study aimed to evaluate the effectiveness of botulinum toxin A (BoNT-A) injection in hemiparetic patients with chronic spasticity in the upper limb resulting from stroke or traumatic brain injury.

Methods: we conducted a retrospective study including 45 patients seen, in our department of Physical Medicine and Rehabilitation, between January 2014 and December 2016. All patients received an injection of BoNT-A (Dysport, 100 U/ml).
