Fig. 4From: Qualitative ultrasonography scale of the intensity of local twitch response during dry needling and its association with modified joint range of motion: a cross-sectional studyThe ultrasonography scale of local twitch response intensity (US-LTR) and scale and effects in maximal range of motion (ROM). a Pre-post maximal ROM (n = 14 legs). b Differences in the ROM between the strong (n = 7 legs) and weak-medium (n = 7 legs) intensities. Values are means and 95 % confidence intervals. *p < 0.05 and **p < 0.001Back to article page
