Objective: This study examined the effects of wearing a tight necktie on cervical range of motion and upper trapezius muscle activity.
Methods And Participants: Thirty computer workers were recruited. First, the active cervical ROM of the participants while wearing or not wearing a tight necktie was measured using the CROM instrument. Subsequently, upper trapezius muscle activity was measured while working at a visual display terminal with and without a tight necktie.
Results: The neck flexion, neck extension, and lateral flexion of the subjects' cervical range of motion were significantly decreased when wearing a tight necktie compared to without it. The activity of the upper trapezius muscle significantly increased when working while wearing a tight necktie compared to without.
Conclusion: It is especially important for male workers to select and tie neckties appropriately in order to prevent musculoskeletal injuries induced by limitation of cervical ROM or repetitive cumulative tension increase of the upper trapezius.

Background: Long-term unobtrusive monitoring of breathing patterns can potentially give a more realistic insight into the respiratory health of people with asthma or chronic obstructive pulmonary disease than brief tests performed in medical environments. However, it is uncertain whether users would be willing to wear these sensor garments long term.
Objective: Our objective was to explore whether users would wear ordinary looking knitted garments with unobtrusive knitted-in breathing sensors long term to monitor their lung health and under what conditions.

The aim of this study was to quantify the number of non-airborne bacteria that can passively penetrate the layers of four mask types (surgical mask, community face mask type 1 (CFM1), biocidal CFM1 and CFM2) and to determine the influence of wearing conditions for the surgical type. A mask wearer simulator consisting of a 3D anatomical replica of the upper airway connected to a breathing pump was used. Wearing time, filtration quality of the mask, fit (loose vs.

Introduction: Wide use of facemasks is one of the many consequences of the COVID-19 pandemic.
Methods: We used an established working memory n-back task in functional magnetic resonance imaging (fMRI) to explore whether wearing a KN95/FFP2 facemask affects overall performance and brain activation patterns. We provide here a prospective crossover design 3 T fMRI study with/without wearing a tight FFP2/KN95 facemask, including 24 community-dwelling male healthy control participants (mean age ± SD = 37.
