The Effects of Scraping Therapy on Local Temperature and Blood Perfusion Volume in Healthy Subjects

Table 1

Blood perfusion volume at different time points in scraping area and non-scraping area (PU), (𝑛=23, 𝑥±𝑆𝐷).

PU	Scraping area (right)	Non scraping area (left)	𝑃 values
Before scraping	0.469±0.103	0.453±0.105	𝑃>0.05
immediately	0.966±0.203	0.465±0.089	𝑃<0.001
15 min	0.685±0.158	0.483±0.076	𝑃<0.001
30 min	0.586±0.075	0.510±0.080	𝑃<0.001
60 min	0.553±0.064	0.504±0.061	𝑃<0.001
90 min	0.558±0.066	0.514±0.052	𝑃<0.001
