Special Issue Information

Dear Colleagues,

EMG, MRI, and ultrasound provide complementary insights into muscle physiology by linking neural activation, tissue structure, and mechanical function. Electromyography, including electrodiagnostic techniques such as nerve conduction studies and needle EMG, evaluates how effectively nerves activate muscles and helps identify neuropathies, myopathies, or impaired motor unit recruitment. However, EMG alone cannot reveal underlying structural changes within the muscle or nerve.

MRI and ultrasound address this gap by providing visualization of muscle size, architecture, edema, and fat infiltration. These measures show whether the muscle has the structural capacity to generate force or is affected by injury, aging, or disease. Ultrasound provides real-time functional context by capturing fascicle behavior, tendon stiffness, and dynamic architectural changes during movement.

Together, these modalities allow researchers and clinicians to connect neural drive, muscle tissue health, and mechanical output, greatly expanding diagnostic and research capability. This Special Issue aims to provide a platform for researchers to share contemporary evidence generated from the integration of imaging and electromyography. Original articles, reviews, and case reports may be submitted to this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Functional Morphology and Kinesiology is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Objectives: This study aimed to examine the intra- and inter-rater reliabilities of panoramic ultrasonographic measurements of the pectoralis minor length (Pm_L), pectoralis minor thickness (Pm_T), and pectoralis minor cross-sectional area (Pm_CSA). Methods: Twenty young male participants aged 19–35 years were recruited [...] Read more.
Objectives: This study aimed to examine the intra- and inter-rater reliabilities of panoramic ultrasonographic measurements of the pectoralis minor length (Pm_L), pectoralis minor thickness (Pm_T), and pectoralis minor cross-sectional area (Pm_CSA). Methods: Twenty young male participants aged 19–35 years were recruited for this study. All participants had asymptomatic rounded shoulder posture (RSP), with a mean acromion-to-table distance of 59.316 ± 9.631 mm. Longitudinal panoramic scans of the Pm of the dominant arm were acquired in three trials of four measurements for all participants. The first two measurements were examined by the same rater on the same day, and the third measurement was performed by a different rater. The same procedure was carried out by the first rater after 30 days for inter-day reliability. Intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs), and minimal detectable changes (MDCs) were calculated to estimate the reliabilities. Results: The intra- and inter-rater reliabilities of Pm_L, Pm_T and Pm_CSA were excellent (all ICC > 0.932; all SEM < 7.4%; all MDC < 20%). Bland–Altman plots demonstrated good agreement with nearly zero mean differences between measurements. Conclusions: Using panoramic ultrasonography to measure Pm_L, Pm_T and Pm_CSA may be considered a reliable method with excellent inter-day, intra- or inter-rater reliabilities. Full article
