David JohanssonFormer neurofeedback practitioner. Retired hockey player. Runner, hiker, and the guy who tested the device on himself before he'd let a client near it.

Achilles tendonitis. Left heel. Years of it.

David had tried everything. Physical therapy. Stretching. Not stretching. Nothing moved it.

But he played hockey, and hockey doesn't wait for your heel. So the routine became the routine: play a game, limp for a week, lace them up for the next game, play through it, limp for another week.

That is not a story about toughness. It's a story about running out of options and deciding to live with the one you've got.

About a week.

He ran the Tendonitis protocol on the heel, alternating with General Inflammation, back and forth, for roughly a week.

Then one morning he noticed the thing you notice when something is missing: no stiffness.

He didn't trust it. So he walked out to the field next to his house and ran sprints. Not a jog. Sprints, on a heel that had punished him for years.

Felt great.

The next day he played a hockey game. Still felt good the day after that.

"I mean, it felt miraculous. It really did. I was elated. It was the best feeling ever."

David, on the week the limp stopped

That was his first experience with the device. It was supposed to be an experiment for the clients. It turned into the end of a years-long problem instead.

The Ron rule.

When David told Resona Health's founder, Mark L Fox, the story about his heel, Mark told one back. He'd given a device to a friend and business partner named Ron. Three months later, Ron called him up out of nowhere.

"So this thing is insane. I've not breathed this well since I was like twelve years old."

Ron, three months after Mark gave him the device

Mark asked the obvious question: you're just now using it? I gave it to you three months ago.

Yeah. Last night was the first time.

David, the guy who tested his on himself the week it arrived, didn't need the lesson. But it's worth writing down for everyone else: devices do not work if you don't use them. The one in the drawer has a zero percent success rate.

What a measurement guy does with a result like that.

David and Shari have since sold the practice. He does training, consulting, and coaching now, and he's building a site where he writes about every product he's tested over the years. The VIBE is at the top of that list. His review covers his own experience, how PEMF works, why a device this small does what it does, and how it compares to units he's tried that cost many thousands of dollars.

He also brings a neurofeedback habit with him: people forget how bad they felt. In the practice, every ten sessions he'd check a client's top ten symptoms, because someone will tell you "I'm not improving" in the same breath as "I only had three meltdowns last week instead of one every day."

So when he coaches someone through the VIBE, he tells them to pick something they can actually measure. The easiest one is sleep. Shari started with the Sleep protocol herself, and it helped her considerably.

And he starts people slowly. A sensitive client gets thirty minutes, not a marathon, until he knows how they respond.

• TendonitisThe one that ended the week-long limp.
• General InflammationAlternated with Tendonitis on the heel; paired with Allergy in the spring.
• AllergyFive pills the first season. Zero this year.
• SleepShari's protocol. Run about an hour before bed, not in bed.

One thing Mark L Fox told David that's worth passing on: run every protocol start to finish. The VIBE doesn't play a single frequency; it plays pairs that change every one to four minutes, like chords in a song. Stopping halfway is like cutting your favorite song off in the middle. Finish the song.
