Contraindications include pregnancy, implanted cardiac devices, uncontrolled epilepsy, and open skin lesions at electrode sites. Always start with the lowest intensity, monitor skin for irritation, and consult a healthcare provider if you have chronic cardiovascular or neurological conditions.

How do I choose the right type of TENS therapy for my specific pain condition?

For acute, localized pain, a high‑frequency (50–150 Hz) stimulation with short pulse width works best; for chronic deep‑tissue pain, a low‑frequency (1–10 Hz) mode with longer pulse width is more effective. Match the unit’s program options to the pain pattern—musculoskeletal versus neuropathic—to optimize analgesic response.

What maintenance and usage tips will help me get the most benefit from my TENS unit?

Clean electrode pads with a damp cloth after each session and replace them when conductivity declines (usually after 200‑300 hours). Store the device in a dry environment, rotate pad placement to avoid skin sensitization, and limit sessions to 20‑30 minutes to prevent tolerance buildup.
