Purpose: To collect age-specific vestibular evoked myogenic potential (VEMP) data and to characterize age-related differences in VEMP parameters using a modified blood pressure manometer (BPM) method of sternocleidomastoid (SCM) muscle monitoring.
Methods: VEMPs were recorded on healthy adults ranging in age from 23 to 84 years with no history of dizziness, neuromuscular pathologies, or cervical complaints. Participants were assigned to 3 groups using a nonprobability static group assignment based on their age. VEMP P1 and N1 latency, threshold, peak-to-peak amplitude, and interamplitude difference (IAD) ratios were obtained at 130 dB SPL.
Results: Statistical differences were detected in peak-to-peak mean amplitude and threshold measures among groups. Post hoc analysis revealed that differences shown were between the young group and both older groups. No significant differences were noted in P1 and N1 latencies or IAD ratios.
Conclusions: This study confirmed a significant decline in VEMP amplitude and increase in VEMP thresholds in healthy older persons. Normative age-related data may be necessary to properly interpret VEMP recordings in a clinical setting when evaluating aging populations. The BPM method utilized for controlling SCM muscle may be a valuable alternative to control SCM muscle contraction when electromyography equipment is not available.

Background: There is limited evidence to inform exercise prescription for deep neck flexor activation out of supine.
Objective: To compare activation of longus colli (LC) and sternocleidomastoid (SCM) from supine to sitting, and to compare the effect of craniocervical flexion (CCF) exercises in sitting on activation.
Methods: Twenty-four individuals without neck pain (mean age 28.

The haptic fidelity of biomimetic materials used in the design of procedural task trainers is of growing interest to the medical community. Shore hardness has been proposed as a method for assessing tissue biomechanics and replicating the results as a way to increase the fidelity of biomimetics to tissues. However, there is limited research on the reliability of human tissue measurements using Shore scales.

Purpose: Assessment of tissue perfusion using near-infrared fluorescence (NIR) with indocyanine green (ICG) is gaining popularity, however reliable and objective interpretation remains a challenge. Therefore, this study aimed to establish reference curves for vital tissue perfusion across target tissues using this imaging modality.
Methods: Data from five prospective study cohorts conducted in three Dutch academic medical centres between December 2018 and June 2023 was included.

Posterior neck, trapezius, and interscapular pain, exacerbated by poor posture such as forward head and rounded shoulders, is common. In this study, we aimed to assess the clinical outcomes of isotonic saline injections at nerve entrapment points (NEPs) within the sternocleidomastoid (SCM) and scalenus medius (SM) muscles for alleviating spinal accessory nerve (SAN) and dorsal scapular nerve (DSN) compression in patients suffering from posterior neck, trapezius, and interscapular pain. In this retrospective study, 68 patients were included, with 34 receiving isotonic saline injections and 34 undergoing Extracorporeal Shock Wave Therapy (ESWT) as a control.

Aim: This study aimed to investigate the relationship between PET and CT parameters and sarcopenia, adipose tissue, and tumor metabolism in esophageal carcinoma (EC) and its impact on survival in EC.
Method: Our study included 122 EC patients who underwent PET/CT for staging. Muscle and adipose tissue characteristics were evaluated, including lumbar (L3) and cervical (C3) muscle areas, psoas major (PM) and sternocleidomastoid muscle (SCM) parameters, and PET parameters for visceral and subcutaneous adipose tissue (SAT).
