14.10.4.5 Stimulation energy
The energy is gradually increased on the second channel (TENS), in order to cause a distinctive tingling
sensation along the painful irradiation of the sciatic nerve.
The gradual energy increase on the first channel must be sucient to obtain visible (or at least palpable)
muscle twitches of the muscles of the lumbar region, which cause hyperaemia.
Note
When TENS is used in combination with an endorphinic programme (such as the Low back pain
programme in this case) the mi-TENS function is inactive.
