Noxious TENS used for what?

• A. Trigger points
• B. Sleep disturbance
• C. Edema
• D. Muscle strengthening

Answer: (A)

Noxious TENS uses a high-intensity, painful electrical stimulus aimed at a localized muscle area to produce counterirritation. The strong input activates pain-modulating pathways and can provoke a local twitch response in a taut muscle band, which helps disrupt a myofascial trigger point and reduce referred pain and muscle guarding. This targeted approach makes it especially useful for relieving symptoms from trigger points.

It’s not typically used for sleep disturbance, edema, or strengthening. Sleep-related issues are better addressed with relaxation or other therapies; edema requires management like elevation and lymphatic techniques; strengthening relies on resisted contractions or NMES—not a noxious, pain-inducing stimulus.
