Welcome to PhotoMed Technologies' Feasibility Study Systems Site

Wellness depends upon myriad bodily systems communicating and working in harmony.

Unfortunately, healing after an injury may stall with no end in sight:

  • Pain-masking medications satisfactorily "manage" the pain for millions of Americans

  • Yet 19 million Americans suffer "unmanageable" chronic pain

  • Another 11 million suffer chronic wounds.

  • Other millions suffer "ouchless" loss of sensation or movement

  • All are waiting for an efficient solution.

The Healing Systems are Waiting to Resume

This site is about the people with impaired sensory & motor functioning, chronic wounds, or unmanageable chronic pain. Future research will be needed to learn how a few photons can prompt the body to resume its ordinary functioning.

The early outcomes from apparently disparate impairments were puzzling. Various conventional explanations could be ruled out. The outcomes provided a unique opportunity to look for common factors among the cases. The detection of improvements was simplified by welcoming people with impairments that were not expected to improve. This website aims to stimulate research using objective feedback for prompting or accelerating healing. Perhaps a researcher can figure out how healing actually works.

PhotoMed's team created the Instant Verification System to collect data as events occurred. The examples introduce phenomena that would not be noticed if they had occurred at the right time. By methods of exclusion, an explanation for the events suggest that the body's automated healing processes can stall for years yet restart in seconds to minutes. The concepts seemed crazy until the team tested them by re-examining events recorded over the past 20 years. Please contact us with your comments, questions, and suggestions.

PhotoMed Technologies' feasibility studies included real-time data recording systems developed by the team to document the therapy, responses, and outcomes. The modular Instant Verification System can be re-configured for follow-on research. The system could save years and $$ for graduate studies.

Figure 1 – Healing state diagram showing that healing is waiting to resume despite that the impaired functioning appears to be unmanageable. Non-invasive therapies often aim to prompt healing to resume with normal functioning (R2N) as the endpoint. Healing is automated in the normal state and requires no interventions (but don't forget diet and exercise) to continue. The Instant Verification System collected real-time recordings of the events when the healing resumed. The value of the data increases by helping to answer old and new questions.

Like with nature videos, real-time recordings show events that unfold, unseen, in everyday life. The events are all ordinary. Would the events be noticed if they had occurred at the proper time?

PhotoMed's real-time recordings show events that can start and progress during a single session (not necessarily the first). Slower progress, like healing after bringing the ends of a broken bone together, might be better captured in slow-motion.


Could it be the time to think differently about the notion that "chronic" means forever?

Could "chronic" mean an interruption on the way back to wellness?

Wellness – healing does its job and doesn’t care what humans name the problem.

However, healing can get stuck. Sometimes for a long time. Like with gravity, healing waits for the time when it can resume its progress.


Non-invasive therapies can restart healing and then get out of the way. The unabsorbed photons from PhotoMed's therapy depart at the speed of light.

Figure 2 – Schematic of healing waiting for the return to normal functioning (R2N). The endpoint is normal functioning. The evidence is that the patient doesn't need more therapy for that injury. Of course, healing may not complete its tasks while you watch. Models support comparisons among different types of inputs, operations, and outputs without requiring knowledge of how each element works. Real-time recordings of events show events surrounding the R2N.

Could it be the delay that makes healing feel special?


Isn't healing the default program of living things?

​​​(Note: many of the website pages were published before this shift in the team's perspectives.)


Could "chronic" mean not-healing?

The team's software engineers spend their days thinking about how "states" switch off or on. They wondered,  could changing "chronic" to the "not-healing state" solve the "it's forever problem"?

Figure 3 - Non-invasive therapies often aim to prompt the return of normal functioning. When ordinary functioning resumes, the outcomes may appear to defy the open-ended logic of "chronic". "Not-healing" and "Healing" can cycle as needed. Please feel free to contact us with ideas about how to present alternatives to the notions about "chronic".

The team tested the new idea by quickly reviewing previously recorded data. They were surprised that almost all of the events appeared to be ordinary. You had to know the "before" state for the events to feel special.


Could persistently cold hands result from a stuck thermostat?

PhotoMed’s developments have been guided by one simple principle: collect as much objective data as possible. Hopefully, the meaning will emerge like a skeleton from dinosaur bones.

Studying chronic pain was challenging because of its invisible nature. The team couldn’t directly measure the pain but they could observe and record the associated impairments.

The team developed thermal imaging systems to record the therapy, responses, and outcomes as they occurred.

Figure 4 - Real-time thermal recording of cold hands responding to the 1st variable-wavelength stimulation. Lighter gray is warmer.

The thermal recordings show that ordinary skin temperature regulation can go offline and resume just like sensory functions. For example, the low temperatures can remain cold and feel cold when they should have become warm or when the feeling would ordinarily be ignored.


Note that the feeling of coldness usually occurs only during the transition toward colder. Keep your hands or body in cold water and the feeling of coldness diminishes. This phenomenon may be life threatening in cold climates.

Figure 5 - This man had had uncomfortably cold hands for 30 years. Everyone was surprised when his hand temperature regulation came back online during the first attempt. The quickness and completeness of his recovery didn’t appear to fit any conventional paradigm. The return to normal functioning (R2N) concept suggests that the ordinary thermo-cycling can get “stuck” and then get "unstuck" to resume ordinary responsive temperature adjustments. Click here for additional examples.

The real-time recordings show that a warming event typically occurs bilaterally when both hands start out cold. Because normal is bilateral, the stuck function appeared to before the left-right control split in the brain. Robert E. Florin, MD, a neurosurgeon suggested that the problem may be like a thermostat that sets the temperature for multiple rooms.

Of course, normal may not mean for the rest of your life. Relief usually doesn't last as long in people having multiple health issues. Could it be that multiple impairments may have a greater tendency towards their functions getting "stuck"?

Could the patient need a different wavelength?

PhotoMed's variable-wavelength therapy allows the user to continuously vary the stimulation across different wavelength ranges. However, healing may require specific but unknown wavelengths. With no missing wavelengths, the user can efficiently test them all from 430 to 690nm.

Figure 6 - Depiction of the output from fixed vs.variable wavelength therapy devices. The Varichrome Pro user can adjust the rate of wavelength variation while using preset wavelength ranges. The aim is to re-direct the body's attention and to provide the energy needed by healing factors.

Like with conventional interventions, you have to try “it” to learn if it works. The VWT testing advances 1000x faster.

How might the variable-wavelength therapy (VWT) work?

Could the therapy’s varying stimulation merely get the body’s attention to prompt a "stuck" function to resume its ordinary tasks? Many non-invasive therapies "work". The variable-wavelength therapy often prompts responses during therapy. The Instant Verification System records events in real time. The ability to replay events bring additional value. The data already collected might save years and $$ for a researcher to make the next big breakthrough. Contact us.

Figure 7 - schematic depiction of responses to a varying or a non-varying stimulus. PhotoMed's variable-wavelength therapy may provide stimulation that would otherwise be insufficient to prompt the R2N.

The team invested years trying to find “how it works” from existing invasive intervention perspectives. That is, to find a complex solution in terms of nerves and bodily systems.  

By rule-it-out logic, the last complex concept flamed out in 2020. The team examined the “it works” data for common features. The “aha” moment arrived upon recognizing that "healing is automated". That is, most injuries heal without becoming chronic.

Data from PhotoMed's studies suggest that the R2N can be prompted by many different wavelengths and other non-invasive therapies. The real-time recordings tell that story.

By analogy, consider what happens when you startle a friend to end their hiccups. There are many ways to startle or re-direct someone's attention.

Could the concept of re-directing attention "explain" how many energy-based therapies might work?


Could the responses be the ordinary next step in the body's automated processes?

For non-healing wounds, could the myriad wound healing factors be waiting for the "right" bit of energy. The factors select which photons to absorb for their quantum bit of energy (wavelength). Could the precise wavelength change from millisecond to millisecond?

The variable-wavelength therapy overcomes the "which-wavelengths-are-needed by the body?" problem.


How long might normal last?

The variable-wavelength therapy (VWT) appears to work more like a jump start than replacing a worn out battery. The photons that aren’t absorbed depart at the speed of light. When the therapy ends, it is up to the body to do the rest.

The return to ordinary functioning doesn’t imply a durability of any length. It represents a return to the functioning that was ongoing prior to the patient’s injury.

In many cases, the return to normal functioning can resolve more than one sign or symptom. For example, re-coordinating muscles can relieve pain because the pain signal is no longer necessary after the underlying problem has been resolved.


Of course, the re-direction of the body's attention doesn't explain all of beneficial outcomes prompted by non-invasive therapies.
