Abstract

This study is a preliminary study to compare the immediate treatment effects of moist hot pack, Thai herbal hot pack, and electrical hot pack on latent trigger point and flexibility of upper trapezius muscle. Eighteen Walailak university students were assessed pain at right upper trapezius muscle and physical activity levels. Pressure pain threshold, visual analog scale, and flexibility of right upper trapezius muscle were recorded before and after 3 hot packs placement for 20 minutes. The result found that there was no statistical significant difference of pressure pain threshold, visual analog scale, and flexibility of right upper trapezius muscle after 3 hot packs placement (p > 0.05). And there are statistical significant difference of pressure pain threshold, visual analog scale, and flexibility of right upper trapezius muscle before and after 3 hot packs placement (p < 0.05). Treatment with 3 hot packs could reduced pain of the latent trigger point and increased flexibility of upper trapezius muscle in the similar result. Nevertheless, Thai herbal hot pack can enhance the feeling of relaxing and relieved pain better than others.
