Table 1

The relative flick threshold (RFT) before, immediately after, two days, and four days after the injections in three groups: hydrogel injected into LHRP, saline injected into LHRP, and hydrogel injected into HHRP.

Groups	Before	After	2 days	4 days
LHRP	1.45±0.62	1.22±0.46	0.94±0.31^∗Δ	0.81±0.29^∗Δ

				Means ± SD, 𝑛=20

^∗𝑃<0.05 compared with the value before the injection.
^Δ𝑃<0.05 compared with the value immediately after the injection.
