A scar can be fully closed and medically stable yet remain painful, numb, itchy or sensitive to touch. Treatment options may include education, graded exposure, movement, manual care, needle-based treatment or non-invasive electrical stimulation.

Dry needling and Dolphin Neurostim are different approaches. The choice should not be made from a headline claiming that one is automatically more effective.

How do they differ?

Dry needling inserts a fine needle through the skin. Technique, depth, target and professional scope vary.

Dolphin Neurostim applies localized electrical stimulation through intact skin without a needle. It may appeal to someone who prefers non-invasive, low-force care or does not tolerate needling or heavier pressure well.

At Lee Strength, this article does not advertise dry needling as a current service.

What does the evidence show?

A 2024 systematic review of dry needling and acupuncture for scars found only two randomized trials, eight case reports and one case series. The studies used different methods and outcomes, so the authors could not perform a meta-analysis or reach a firm conclusion about effectiveness.

Dolphin-related scar publications report encouraging short-term changes, but much of that evidence consists of small or uncontrolled studies. No credible direct head-to-head trial establishes that Dolphin is superior to dry needling for scar-related pain.

The manufacturer's comparison uses percentages from separate studies. Comparing those numbers does not create a randomized comparison between treatments.

What should guide a treatment trial?

Before treating a scar, I would consider:

  • whether the wound is fully healed and medically stable
  • pain quality, numbness, swelling and skin integrity
  • the person's comfort and preference
  • the activity being limited
  • whether progress can be measured

A useful outcome might be greater comfort with clothing, touch, kneeling, reaching, bending or exercise. An immediate change can be informative, but durability and improved function matter more.

Neither approach should be presented as dissolving every adhesion, erasing scar tissue or correcting distant symptoms throughout the body.
