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

Abstract

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.

The value of ultrasound-guidance of nerves and muscles for patient tolerance and parameters electrodiagnostic studies

“…The most commonly chosen muscles were the psoas and teres pronator muscles (40 versus 1 and 21 versus 13, respectively), the other muscles were too infrequently punctured to identify a difference between the two groups. USG muscle has been used to facilitate muscle biopsies increase the accuracy of standard needle electromyography (EMG) for non-routine muscles such as the extensor indicis muscle and tibialis posterior, for plegic muscles, for junior resident physicians or scanning EMG ( Billakota et al, 2016 , Connell et al, 2023 , Elleuch et al, 2021a , Elleuch et al, 2021b , Gentile et al, 2020 , Karvelas et al, 2016 , Maitland et al, 2022 , Padua et al, 2023 ). In the study on residents, needle electrode placement accuracy improved with residency years.…”

Energy use and its contributors in hotels: protocol for a systematic review and meta-analysis

“…In the last 20 years, many investigations into the use of resources have been developed in the sectorlargely focused on energy use, but also on the consumption of fuels and water (MECHRI;AMARA, 2021). The number of publications in specialized journals on the subject has also increased exponentially over the last 40 years (MULET-FORTEZA et al, 2019).…”

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

“…The use of US requires expertise, particularly for deep, thin or pathological muscles that are considered key in diagnosing the neural damage level [1,2]. For example, the flexor carpi radialis muscle (FCRM) is considered a key muscle in diagnosing the neurological lesion causing upper limb extensors' deficiency [3].…”
