bacKGrouNd: appropriate evaluation and management of dysphagia are essential in neurological disorders. however, there is currently a lack of a simple yet reliable method for dysphagia evaluation. aiM: this study aimed to investigate the usefulness of new dynamic M-mode ultrasonography (us) parameters of suprahyoid muscle (shM) to evaluate dysphagi...
The measurement of skeletal muscle mass is essential for the diagnosis of sarcopenia. Muscle ultrasonography has emerged as a useful tool for evaluating sarcopenia because it can be used to assess muscle quality and quantity. This study investigated whether muscle ultrasonography is effective for estimating appendicular skeletal muscle mass (ASM) a...
Objective
The diagnostic values of measuring median nerve (MN) stiffness and vascularity with shear wave elastography (SWE) and high-definition (HD) color were investigated in carpal tunnel syndrome (CTS).
Methods
Seventy patients (123 wrists) with CTS and thirty-five healthy volunteers (70 wrists) were enrolled. Based on nerve conduction studies...
Objective
This study aimed to investigate the utility of facial nerve ultrasonography in the functional and structural assessment of early-stage Bell’s palsy and the prognostic value of facial nerve ultrasonography in Bell’s palsy.
Study Design
Prospective longitudinal study.
Setting
Single center, a university-affiliated neurology clinic.
Subje...
Background:
Because of limitations of conventional tools for diagnosing optic neuritis (ON), transorbital ultrasonography (TOUS) was introduced as a promising tool to evaluate the optic nerve. However, studies demonstrating its utility are scarce.
Objective:
To assess the practical diagnostic value of TOUS in patients with ON along with other di...
Introduction
Visual evoked potentials (VEP), magnetic resonance imaging, and the optical coherence tomography (OCT) have been used to evaluate the functional and morphologic status of the afferent visual pathway. However, these utilities have some limitation to evaluate optic nerve pathology in the early stage. Recently transorbital ultrasound (US)...
Background and purpose:
Diabetes mellitus (DM) has been proposed as a risk factor for carpal tunnel syndrome (CTS), but this remains controversial. We investigated the association between DM and CTS using both ultrasonography (US) and nerve conduction study (NCS) data.
Methods:
We analyzed a prospectively recruited database of neuromuscular US a...

... The golden years, as always, spawn their own issues, with sarcopenia and gradual muscle mass and function loss being the leading ones [53]. Ultrasonography using a feature that provides with muscle mass and quality assessment becomes an unreplaceable tool in detecting age-related pathology [54]. The ultrasonography method that includes the assessment of body areas, such as muscle thickness, area of crosssection, and intramuscular fat concentration, provides a comprehensive picture on the structural changes due to age and helps to define the influence of age on muscle alterations [55]. ...

... CSA measurements at the outlet had possibly shown other results. In addition, other promising ultrasound techniques were not used in this study-particularly, the evaluation of echogenicity, the intraneural blood flow using Doppler ultrasound [9], or ultrasound elastography-to assess changes in stiffness of the nerve [34,35]. These techniques may provide additional information for CTS diagnosis but need more clinical evaluation. ...
... ONSD of the unaffected eye was similar to controls [17]. Kwon et al. studied 17 patients with new-onset unilateral optic neuritis and found median ONSD to be modestly higher in affected eyes than in unaffected eyes, measuring 5.51 mm and 5.05 mm, respectively [18]. While their findings are modest, they are supportive of the findings from Lochner's study. ...
... Additionally, recent studies outlined the procedure and confirmed the validity and reliability of ultrasound use in the management of facial nerve pathologies including Bell's palsy. 3 To conclude, we highlight the potential/novel role of ultrasound examination in Bell's palsy in two ways: First, ultrasound allowed precise confirmation of the inflamed/edematous facial nerve along with ruling out any local pathologies. Second, and perhaps more important, US permitted localization of the exact site for injection, which helps reduce the required blood drug concentration of corticosteroids and contributes to better recovery (with fewer side effects) during follow-up. ...
... Similar findings were observed in comparison of parameters of electrodiagnostic tests between CTS and DM-CTS groups another study. [14][15][16] Comparison between diabetic participants using oneway ANOVA revealed that impaired glycaemic status made a statistically significant difference in the electrophysiological severity of CTS in right and left hand at only 10% level of significance (F= 2.465 p = 0.089). No significant association was found between duration of diabetes and severity of CTS. ...
