Administration of Transcutaneous Electrical Nerve Stimulator (TENS) Manipulation in a Chronic Constriction Injury Rat Model

1 Begin by fixing the rat2 from the transcutaneous electrical nerve stimulation, 3 or, TENS treatment group, in a rodent restraint, 4 exposing the affected limb laterally. 5 Administer a low-frequency electrical stimulation 6 with the electrode applied on the leg around the nerve, 7 and to the Zusanli and Sanyinjiao points 8 using the TENS device for 10 minutes. 9 The sciatic function index, or SFI, 10 in the injury with TENS group 11 improved significantly 12 compared to the injury group alone.

13 The improvement was significant in the FSN group 14 relative to the TENS group. 15 The SFI of the Sham, FSN, and TENS groups 16 did not have any significant difference from each other, 17 proving the safety of the treatment groups. 18 Improved amplitude of CMAP 19 relative to the injury alone group was observed.

20 Similar observations were observed 21 with the latency peak in the injury 22 with TENS treatment group. 23 The CMAP and latency peaks of the treatment groups 24 did not differ significantly from each other. 25 The CMAP amplitudes and latency of all three groups 26 were statistically similar.
