Purpose: This study was conducted to investigate changes in the cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort following the wearing of a trunk brace during smartphone watching. Methods: To calculate the number of subjects for this study, an analysis with G^*Power was performed at a statistical power of 0.8, an effect size of 0.5, and a significance level of 0.05, based on the results of a preliminary experiment on five subjects. In total, 27 adult men and women were recruited who had been informed of the study's purpose and process and had agreed to participate. All subjects watched content on a smartphone for 20 minutes in the same posture and conditions while wearing and not wearing a trunk brace, and then their cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort were measured. Results: Compared to the non-wearing of a trunk brace, the wearing of a trunk brace resulted in a statistically significant smaller decline in cervical extension and right-side cervical rotation (p<0.05). When the subjects wore a trunk brace, their right- and left-side cervical and right-side lumbar pressure pain statistically significantly improved when compared to not wearing a trunk brace (p<0.05). They also perceived a significantly lowered level of comfort 20 minutes after wearing a trunk brace compared to immediately after wearing it (p<0.05). Conclusion: The trunk brace was effective in reducing declines in right-side cervical rotation and the occurrence of left- and right-side cervical and right-side lumbar pressure pain. The findings indicate the need to improve the perceived comfort of trunk braces.

The purpose of this study was to evaluate the comfort and fabric hand characteristics of selected lining fabrics made of acetate and polyester. The comfort of the linings was determined by human subjects wearing suit blazers constructed with different lining materials in an environmental chamber controlled at $30.6^{\circ}C$ air temperature and 50% relative humidity. The hand characteristics of the lining fabrics were determined by five trained panelists using standard fabric reference samples. The effect of lining fabrics on the subjects' thermal sensations was not statistically significant. But the subjects voted warmer when wearing the polyester surah lined blazer or the polyester taffeta blazer than wearing the acetate blazers. The results of the subjective comfort evaluation indicated that, in general, the subjects rated the acetate linings significantly less sticky, clammy, damp, and non-absorbent than the polyester linings. Acetate surah was rated a little higher than the other acetate fabrics on these comfort descriptors. The results of the subjective hand evaluation indicated that the lining fabrics rated low on the geometric and mechanical hand characteristics and rated moderate on noise. Acetate surah scored the highest on most of the hand characteristics, whereas, polyester taffeta scored the lowest.

This study analyzed the pressure, subjective wearing comfort, and design preference of brassiere shoulder straps among women in their 20s and 40s. Experimental clothing was made by different shoulder strap designs on a brassiere. In the four designs (A-D), the front attachment points of the shoulder straps were the same, but the back attachment points were different. Three of them (E, E1, E2) were of a halter neck design, with different front attachment positions. The pressures of A-D were measured at the position passing through the shoulder line (P1), and E-E2 was measured at the back neck (P2) as well as at P1. Subjective wearing comfort and design preference were rated on a 7-point Likert scale. A was determined to exert the highest pressure at the neck side of the design in the pressure measurement analysis of A-E2, whereas E1 exerted the lowest. E was measured to have the highest pressure among the E-E2 designs, whereas E2 had the lowest. Participants preferred A the most and E the least in regards to the subjective wearing comfort of A-E. Thus, participants deem A to be the most comfortable despite the high strap pressure. However, E was the most favored design, despite its poor wearing comfort. Participants' subjective impressions of E-E2 were that E2 was the most uncomfortable, but its design was the most preferred. Consumers' design preferences and subjective impressions of wearing comfort did not match.
