A Powerful Choice for Multiple Pains Our powerful, versatile TENS unit is still easy to personalise and customise. When you have those hard to reach, deep pains that just keep coming back, choose Max Power Relief. It is perfect for those who may experience pain in the lower back or recurring knee and shoulder pain. This highly customizable TENS unit has modes to reach most of your pains. Take it to work, use it at home or while travelling. First, select the pain mode (i.e., lower back or arm) and then choose the intensity level. The programmes are interchangeable and effective for multiple body parts. (Read the complete instruction manual carefully to safely and correctly use this pain management unit). Expect variations of tapping, tingling,massage-like sensations or even mild muscle contractions. Always start with low intensity and increase slowly. If the sensation feels uncomfortable, decrease the intensity and/or change the programme. If the sensation becomes weaker or disappears, increase the intensity. Start with one 15 minute session. Always turn unit off with pads still on. Rate your pain to cheque your progress, 1 low to 10 high. Stop therapy session if pain has reduced or stopped. Caring for long life pads: Omrons Long Life Pads (PMLLPAD) are durable, comfortable and gently adhere to your skin.
