Table 4.

Short-term and long-term effects of FSN and TENS groups on NDI.

	Pre-tx on day 1	Day 8	P a	Day 15	P b
FSN	8.43 ± 4.09	6.83 ± 4.39	0.010	4.96 ± 4.23	<0.001
TENS	10.16 ± 5.84	8.33 ± 5.73	0.036	7.36 ± 5.70	0.001

Data were expressed as mean ± SD; P value was tested with a paired sample t-test. ^aCompares 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. FSN: Fu's subcutaneous needling; TENS: transcutaneous electrical nerve stimulation; NDI: neck disability index.
