Which disorders responded to PhotoMed’s new algorithm?


Hundreds of volunteers attended clinics and studies that aimed to identify disorders that might respond to PhotoMed’s non-invasive therapy. The Instant Feedback System™ connected dots among inputs, responses, and outcomes year before AI became popular.

The new algorithm didn’t produce responses or relief in about 2/3 of cases. That was expected because the people hadn’t responded as expected to previous attempts.

Some responses, when the therapy worked, puzzled PhotoMed’s team. They wondered, how could gait and swallowing improve in people with Huntington’s disease? Or, normal sensation return after years of absence due to diabetes.

Recorded data let the team solve the puzzle. They organized the disorders by innate function rather than by clinical description.


Because many disorders had no defined target to zap. Some disorders did not have an “ouch” factor.


Disorders that responded organized by functional impairment:


Sensory impairments

  • Loss of sensation in fingers or toes

  • Diabetic peripheral neuropathy (DPN)

  • Complex regional pain syndrome (CRPS or RSD)

  • Post-surgical pain

  • Post-chemotherapy pain

  • Neuropathy from other causes, such as stroke or spinal cord injury

  • Fibromyalgia

  • Sympathetically mediated (or maintained) pain, especially people who have benefited from a sympathetic nerve block or sympathectomy

  • Post-herpetic pain (shingles)

  • Phantom pain in limbs and reconstructed skin

  • Mirror-neuron synesthesia


Motor impairments

  • Loss of grip strength and movement

  • Lost range-of-motion

  • Loss of movement after stroke (therapy helps overcome acquired non-use)

  • Carpal tunnel syndrome

  • Muscle imbalance, i.e. scoliosis

  • Loss of coordination in gait & swallowing, and choreic movements from Huntington’s disease



  • Restart non-healing wounds at any stage

  • Accelerate slow-healing wounds

  • Diabetic foot ulcers and loss of sensation

  • Venous stasis ulcers, bed sores

  • Improve scars, keloids


  • Abnormally cold or hot hands, with or without pain

  • Thermoregulation, gut, bowel, and bladder function after spinal cord injury

  • Complex regional pain syndrome (CRPS or RSD)

  • Raynaud's syndrome
