Prototype of the wearable thermo-device (WTD) used in this study. (a) The stimulation area that cools/heats the skin surface is approximately 4.5 × 5.5 cm. (b) Intervention scene using WTD. A thermocouple (solid arrows) was set up to measure the skin temperature during the intervention. (c) The measurement point of trapezius muscle hardness and skin temperature (solid arrow) and the stimulation area of WTD (dotted area)
