Abstract
Introduction. Prolonged sitting has been associated with the impairment of microvascular dilator function of the upper limbs with a decrease in blood flow. Ergonomic mouse pad including wrist support could minimize the risk of health disturbances related to impaired blood supply in hands while working with computer.
The aim of this study was to explore an association between body mass index (BMI) and wrist surface temperature in dominant hand while using 4 different types of computer mouse pads.
Material and methods. 4 volunteers, sedentary occupation workers with their dominant right hand were selected. Each volunteer was asked to work with four different mouse pads on different days for three continuous hours. The skin surface temperature of the right wrist was measured with high-resolution medical digital infrared camera ICI ETI 7320 Pro at the start and after every 15 minutes of the experiment. Temperature changes were evaluated in association with BMI of study participants.
Results. Wrist surface temperature decreased in all participants, regardless of BMI, however at different paces. A strong correlation with BMI and wrist temperature was found when using Wristband2 (rs = 0.701, p<0.01), slightly weaker positive correlation – for Wristband1 (rs = 0.484, p<0.01) and standard mouse pad (rs = 0.499, p<0.01), while strong negative correlation (rs = –0.808, p<0.01) was found in a person with the lowest BMI (21.9). On the contrary, no correlation was found between the average temperature of the right wrist surface and volunteer with the highest BMI (31.2).
Conclusions. Higher BMI is associated with higher wrist surface temperature when using a computer mouse for prolonged periods. Low BMI is associated with faster and more prominent decrease in wrist surface temperature due to a thinner fat heat-insulating layer. Mousepad design is associated with extent of changes in wrist surface temperature.
