Does a light pressure instrument assisted soft tissue mobilization technique modulate tactile discrimination and perceived pain in healthy individuals with DOMS?

This investigation measured the effects of a light pressure instrument assisted soft tissue mobilization (IASTM) technique on tactile discrimination and pain perception in individuals after strenuous exercise. Twenty-three subjects underwent three different testing sessions: baseline measures and exercise, 24-hours (post) treatment and measures, and 48-hours (post) treatment and measures. Outcomes included two-point discrimination (TPD) and pressure pain threshold (PPT). Statistical analysis included parametric tests. For TPD, a significant difference was observed between all time points (p <.001). Post-hoc testing revealed a significant difference from baseline to 24 hours post (p <.001) and 48 hours post (p <.001). For PPT, a significant difference was observed between all time points (p <.001). Post-hoc testing revealed a significant difference from baseline to 24 hours post (p =.005) and 48 hours post (p =.003). A significant difference was not observed between 24 to 48 hours post for TPD and PPT (p =1.00). The results suggest that a light IASTM technique may produce a neuromodulation effect on local tactile descrimination and pain perception in individuals with DOMS.
