What should you know about Chattanooga Primera TENS NMES?

TENS sends mild electrical pulses through skin electrodes and is used to change how pain signals are perceived. NMES is set to produce a visible muscle contraction and may support muscle re-education or strengthening during rehabilitation. The modes are not interchangeable: electrode placement, intensity, pulse pattern, and session plan should match the intended goal. A strong sensation is not evidence that treatment will work better.

Use the programme, electrode positions, and session schedule supplied by your physiotherapist or prescribing clinician. Apply intact electrodes to clean, dry skin, connect the leads before raising intensity, and increase stimulation gradually. TENS should feel firm but comfortable; NMES may create a controlled contraction without sharp pain. Switch the unit off before moving electrodes. Check the skin afterward and replace worn or poorly adhering pads.

Do not place electrodes across the chest, over the front or side of the neck, on the head, or over broken, infected, or numb skin. Get clinical guidance before use if you have a pacemaker or another implanted electronic device, are pregnant, have epilepsy, impaired sensation, circulation problems, or an unexplained painful area. Do not use stimulation while driving, bathing, or operating machinery.

Stop stimulation and remove the electrodes if you develop burning pain, marked skin irritation, dizziness, palpitations, new weakness, or worsening symptoms. Seek urgent medical care for chest pain, breathing difficulty, fainting, sudden one-sided weakness, or a severe allergic reaction. For persistent redness, blistering, or pain after a session, keep the device off and contact the treating clinician before using it again.

Ask which mode matches your goal, exactly where each electrode belongs, what sensation or contraction to expect, and which programme and intensity range to use. Confirm how to judge skin reactions, when the plan should be reviewed, and whether your medical conditions or implanted devices change where or whether stimulation is appropriate.
