Effectiveness of FSN and TENS groups on sleep quality via self-reported PSQI questionnaire.

	Pre-tx on day 1	Day 8	P a	Day 15	P b
FSN	10.67 ± 3.05	10.43 ± 2.69	0.504	9.93 ± 2.74	0.030∗
TENS	10.80 ± 3.81	10.26 ± 3.67	0.290	10.26 ± 3.18	0.252

Data were expressed as mean ± SD; P value was tested with a paired sample t-test.^a Compares the value in pre-Tx and on day 8 of FSN or TENS group. ^bCompares the value on day 8 and on day 15 of FSN or TENS group. Asterisks (^∗) showed the P < 0.05. FSN: Fu's subcutaneous needling; TENS: transcutaneous electrical nerve stimulation; PSQI: Pittsburgh sleep quality index.
