A partial list of disorders that have responded within 2 visits

PhotoMed's team sponsored and supported feasibility studies for the variable-wavelength therapy. The responses and outcomes to the therapy exceeded everyone's imagination.

A primary reason for skepticism was (and still is) that the team found no predictions of the observed responses and outcomes in tomes on chronic pain.


How could unrelenting "nothing works" chronic pain simply vanish? It would take nearly 20 years to find the solution --> in the language of rehabilitation. The practitioner uses non-invasive devices aimed to prompt the body to resume its normal healing.  The measure of success, normal functioning, is easy to detect when completed - the patient doesn't need more therapy.

The founder, a skeptical mechanical engineer, led the team to utilize industrial strategies for testing the new therapy while collecting real-time data. Today, PhotoMed's sophisticated recording system is called the Instant Verification System.


Objective measures (sensory, motor, skin temperature, & wounds) and TIME provided comparative data for improving the therapeutic efficiency. The efficiency of the therapy improved through finding wavelengths that appeared to be more efficient at prompting a physiological response and beneficial outcome.

Attempts failed to quantify possible wavelength-dose-response relationships for abnormally cold hands or feet. The problem was that there were 300 wavelengths to test. Worse, the dose calculations didn't compute when no more therapy was needed. It now appears that the body had received the right signal to restart its normal functioning or healing.

Another challenge for studying non-invasive therapies is that the body continues with its own healing after the therapy ends. The responses may be indistinguishable from "normal" except for the months or years of delay. Could it be the "before" story that makes the responses seem special?


Pioneering relief for patients enduring "nothing works" chronic pain

The team specifically asked researchers to reduce selection bias by primarily inviting their patients with long duration and high-impact pain for whom nothing had worked before. Traditional pain studies that aim to confirm a hypothesis intentionally exclude  people that aren't expected to respond to the intervention.

PhotoMed's team intentionally invited people with the "nothing works" types of pain. These unfortunate people were enrolled that everyone agreed that the injury presented no reasonable expectation of improved functioning. These zero-expectation "controls" responded by returning to normal functioning while being documented by the recording system.

The previously failed interventions provided randomized "control arms" to test the null hypothesis: "the new therapy will not provide greater relief than any previous intervention". At the beginning, no one (including the founder and team) expected that the therapy might "work" for so many seemingly disparate disorders.


The engineers focused on quick events that could be measured during a single visit without the person leaving the room. With their permission, the entire visit was recorded, sections were cropped and shown on this site.

For example, "George" showed that sensations in BOTH of his feet can resume so quickly that his skin-touch-location maps are not aligned with his feet. His feet had been off-line for 8 years a probable side effect from 40 years of diabetes. To be enrolled patients with numb feet were asked if it would be okay if their "before numb" pain returned along with improved sensations. Only one person opted out.

Quick Events 2021-06-04.png

Patterns emerged from the data surrounding quick events. Many, possibly most, events involved the whole body. Like many wellness therapies, both hands warm and return to normal functioning rather than an interventions such as a nerve block which shuts off thermoregulation in a single limb. See the skin temperature page.

The quick-event functional-level responses and outcomes suggest new areas of research that may be economically achieved using the Instant Verification System.

Reproducing the return to normal functioning

More than 500 people volunteered in the studies at 7 sites (California [2], Massachusetts, Colorado, Pennsylvania [2], Florida). Many participants arrived with multiple sites of unresponsive pain. Review of study data suggests that many volunteers had been sent for physical medicine and rehabilitation (PM&R) after “nothing worked” with conventional interventions.

Today, it appears that the people who have had their pain adequately "managed" by pain-masking interventions do not respond with quick events or fully return to normal functioning. They may report feeling "better" but few would report that they "feel normal again".

Practitioners may recognize similar responses and outcomes from other non-invasive therapies.

Doesn't the return to normal functioning describe the basic program of life itself?
