step 2/8

We will start with the legs. There will be a pair of electrodes on each leg (positions shown in the images) that will reveal any restless leg movements overnight.

If you have hair on your legs, shave the area discussed here before proceeding.

Beginning with the left leg, use an alcohol swab to clean a 5cm wide, 10cm long area in the 'valley' between the outer shin and calf, about one third to one half of the way down the leg (see image for guide).

Abrade the area with abrasive gel for 30 seconds.

Repeat with the other leg.

Once the area is dry (or after using a discarded alcohol wipe to remove excess gel), attach 2x square electrodes to each leg (where the white dots are in the images)
