AI Article Synopsis
- Frontal vehicle collisions can severely strain the cervical muscles of drivers, potentially causing injuries during impact.
- This study utilized a modified dummy in sled tests to analyze the muscle responses (strain and load) of key cervical muscles: SCM, SPL, and TRP, revealing that most strains exceeded injury thresholds.
- The findings show the SPL experienced the most significant injury, while the study overall aims to enhance understanding of cervical muscle responses to inform better occupant protection in vehicles.
Article Abstract
Frontal vehicle collisions can cause injury to a driver's cervical muscles resulting from intense changes in muscle strain and muscle load. This study investigated the influence of collision forces in a sled test environment using a modified Hybrid III 50th percentile dummy equipped with simulated spring-type muscles. Cervical muscle responses including strain and load of the sternocleidomastoid (SCM), splenius capitis (SPL), and trapezius (TRP) were analyzed, and muscle injury was assessed. The SCM, SPL, and TRP suffered average peak muscle strains of 21%, 40%, and 23%, respectively, exceeding the injury threshold. The average peak muscle loads of the SCM, SPL and TRP were 11 N, 25 N, and 25 N, respectively, lower than the ultimate failure load. The SPL endured the largest injury, while the injuries to the SCM and TRP were relatively small. This is a preliminary study to assess the cervical muscle of driver during a frontal vehicle collision. This study provides a foundation for investigating the muscle response and injury in sled test environments, which can lead to the improvement of occupant protections.

Objective: In this study, we aimed to determine the effects of 2-week neuromuscular electrical stimulation (NMES) on quadriceps muscle atrophy and lower extremity motor score in individuals with subacute incomplete cervical spinal cord injury (SCI).
Methods: This stratified randomized controlled trial, conducted in the advanced critical care center of a university hospital, comprised 49 individuals with American Spinal Injury Association (ASIA) impairment scale grade C and D incomplete cervical SCI. The participants were stratified based on the ASIA impairment scale grade and randomly assigned to the control (n = 25) or NMES (n = 24) group.

Background: Occult papillary thyroid carcinoma (PTC) refers to the PTC accidentally found due to its occult lesions. Classic, as the most common subtype of PTC, is usually considered to have a low degree of malignancy and a favorable prognosis. Currently, the American Thyroid Association Management Guidelines adopted active surveillance (AS) as an alternative to immediate surgery in some low-risk PTC patients with less than 1 cm in diameter.

The presence of a positive deep surgical margin in tongue squamous cell carcinoma (TSCC) significantly elevates the risk of local recurrence. Therefore, a prompt and precise intraoperative assessment of margin status is imperative to ensure thorough tumor resection. In this study, we integrate Raman imaging technology with an artificial intelligence (AI) generative model, proposing an innovative approach for intraoperative margin status diagnosis.

The patient was a 33-year-old woman with no family history of a similar disorder. At one year of age, she exhibited scoliosis and respiratory failure, necessitating a tracheostomy performed at 5 years of age (1990s). During that time, the patient was provisionally diagnosed with "non-Fukuyama congenital muscular dystrophy" via muscle biopsy.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.
Methods And Materials: A total of 209 patients participated in the study.
