How quickly might you expect a profound loss of sensation to come back "online"?

Throughout the development of the Vari-Chrome Pro, crazy-fast "quick events" made the team skeptical.

The outcomes challenged notions about how long a loss of sensation or abnormal motor functions might be expected to last.

Could this diagram unify 20 years of data?

Could the quick events occur only if the healing processes are complete except for the last step?


The switch back to the healing state may occur as a quick event that surprises the patient. Patients may flinch, gasp, or spontaneously verbalize their surprise. They quizzically look at their "returned" body parts while adding cross sensory stimulation.


What might these quick events be called?

For lack of finding a googled term, we propose a general term "cross-sensory correction" (CRC) for the outcomes of the quick sensory and motor quick events. The team's nerdy software engineers suggested that some "if/then" branch opened up awareness.

Volunteers in PhotoMed sponsored studies typically reported that they had volunteered to relieve chronic pain and that had zero expectation of getting back normal functions.


Conversations shifted from pain to "I can't believe..." as they tested their newly resumed sensory abilities.


The volunteers who experienced a quick return of sensations typically had experienced numb fingers or feet for more than a year. The numbness ranged from partial ("Brenda") to profound ("George").

The return to normal healing prompts stalled processes to resume at the state that they are at that instant. For example, cold hands don't sudden become a different temperature but warm like they normally would.


1. Could touch sensation have been turned "off" and the therapy turned it "on" again?

“Brenda’s” right fingers were numb after an elbow surgery that did not relieve her elbow pain. She enrolled in a PhotoMed sponsored feasibility study to see if the therapy might relieve her pain. Brenda’s pain was temporarily relieved. The Instant Verification System recorded her visits.

However, Brenda was excited to explore her “new” finger sensations as she put them to a test. (0:54)


The unexpected resumption of sensation maybe tested via cross-sensory perception. The person may be perplexed such that they look intently at their fingers while touching or moving them. Touching familiar objects also seems to help with accepting the sensations that would normally have been taken for granted.


Interesting events may be efficiently found by reviewing clips at high speed (5x in this video). The high-angle camera in the Instant Verification System recorded details that the not noticed by the technician.

2. Weird, could sensations come back online, but not be aligned with his feet?

“George” arrived at his first visit walking stooped over from back pain, or so the practitioner thought.


Rather than responding to pain, he was looking at his profoundly numb feet to keep from falling. 40 years of diabetes had taken a toll on his body. He and his wife reported that he hadn’t felt his feet for about the last 8 years.

During his first visit, his back pain lessened. That was a win for George. He hadn’t considered that the “dead” nerves in his feet might be revived.

Therapy to his feet at his first visit yielded a “maybe” to strong pressure applied to his toes.

George returned a week later not looking at his feet. He complied with a request to not move or look at his feet until asked. The technician didn't explain how often that sensations in other volunteers had returned after years of being offline.

Within minutes after the test therapy began, George reported touch sensations from a 19 grams vonFrey monofilament. Then on down to 5.1gm.

However, George reported erroneous locations when he reported being touched. He didn't know that his answers were wrong.


Could cross-sensory stimulation be needed to keep touch maps normally aligned?

For more than 20 minutes, George could feel being touched but reported being touched at a different location. The maps would have realigned if George had moved or looked at where he was being touched.

Watch as George looks at his feet for the first time after a few minutes of testing. The time bar starts when he first received a treatment during his 2nd visit. (2:05)

Events captured by the Instant Verification System suggest that future researchers might save time and $$ exploring the underlying phenomena. Contact PhotoMed for more information.
