Experimental Design Showing Treatment Parameters for Each Modality in Each Model

Condition	Treatment
	SCS	TENS	MA
SNI	Internal implantation, 4 day, 15 min per day, starting 2 wk after SNI, behavior test before and after 30 min treatment.	Four electrodes on paravertebral muscle, 4 day, 15 min per day, starting 2 wk after SNI, behavior test before and after 30 min treatment.	Two needles one on left Sanyinjiao (SP6) and other on left Zusanli (ST36) acupoints, 4 day, 15 min per day, starting 2 wk after SNI, behavior test before and after 30 min treatment.
Inflammatory	Internal implantation, 4 day, 15 min per day, starting 24 hr after 3% carrageenan injection, behavior test before and after 30 min treatment.	Two electrodes on knee joint on ipsilateral side, 4 day, 15 min per day, starting 24 hr after 3% carrageenan injection, behavior test before and after 30 min treatment.	Two needles one on left SP6 and other on left ST36 acupoints, 4 day, 15 min per day, 24 hr after 3% carrageenan injection, behavior test before and after 30 min treatment.
Non-inflammatory	Internal implantation, 4 day, 15 min per day, starting 24 hr after second injection of saline, behavior test before and after 30 min treatment.	Two electrodes on gastrocnemius muscle on ipsilateral side, 4 day, 15 min per day, starting 24 hr after second injection of saline, behavior test before and after 30 min treatment.	Two needles one on left SP6 and other on left ST36 acupoints, 4 day, 15 min per day, 24 hr after second injection of saline, behavior test before and after 30 min treatment.

SCS: spinal cord stimulation, TENS: transcutaneous electrical nerve stimulation, MA: manual acupuncture, SNI: spared nerve injury.
