Physiotherapist David Putrino was engaged on a vibrating glove to assist deaf individuals expertise reside music when a pal talked about that the identical expertise would possibly cease tremors in individuals with Parkinson’s illness.
Putrino, director of rehabilitation innovation for Mount Sinai Well being System in New York Metropolis, was intrigued. The pal’s father had Parkinson’s, so that they positioned the brand new gadget on his wrist, and the tremors stopped of their tracks.
“He was a former pianist and sat down and began enjoying. It was fairly dramatic,” Putrino recalled.
And that is when Putrino and his group pivoted and commenced investigating the brand new gadget for Parkinson’s-related tremors.
A new study exhibits that they are on to one thing. The gadget, which is worn on the wrist or ankle and is roughly the scale and weight of a smartwatch, could also be a protected and efficient option to cut back resting tremors in individuals with Parkinson’s illness.
The expertise sends indicators to the mind to disrupt the irregular rhythms that trigger resting tremors. The standard Parkinson’s tremor tends to happen when muscle tissues are relaxed, corresponding to when fingers are resting on the lap. The tremors have a tendency to minimize when the physique is engaged in one other exercise or throughout sleep.
“Drugs and even a number of the extra invasive interventions like deep brain stimulation (DBS) remedy intention to interrupt up the irregular synchrony between mind areas to enhance signs” for Parkinson’s sufferers, Putrino defined.
For the brand new examine, 44 individuals with Parkinson’s used the gadget on their wrists or ankles with two vibration patterns to verify it was protected.
The reply was sure.
“Sufferers didn’t report any critical hostile occasions,” Putrino mentioned. “Some individuals turned the depth down, whereas others mentioned it was nice.”
The examine was not designed to point out if or how nicely the gadget works, however most people reported a discount in tremors whereas receiving the vibrating pulses.
“Sending competing messages to the mind to disrupt irregular synchronicity by the wrist or ankles will help cease tremors,” Putrino mentioned.
The following step is a bigger examine evaluating the gadget to a placebo gadget for each day use, he mentioned.
If follow-up research present comparable outcomes, the gadget could also be right here before . “There isn’t any purpose why this cannot be made inside 5 years so long as research proceed to be encouraging, and we proceed to see no hostile reactions,” Putrino mentioned.
The gadget will not be a panacea for different forms of tremors with completely different neurologic causes. Researchers do plan to check the vibrating gadget in spinal cord injury, stroke and different forms of neurologic disabilities, he mentioned. It is now getting used to permit deaf individuals to expertise reside music.
The findings had been printed Nov. 18 within the journal Frontiers in Human Neuroscience.
Dr. Michele Tagliati, director of the Motion Issues Program at Cedars-Sinai in Los Angeles, reviewed the findings.
“Tremor in Parkinson’s illness is an attention-grabbing symptom, however it’s typically not probably the most disabling symptom,” he mentioned.
There aren’t nice methods to deal with tremors in Parkinson’s illness proper now. Surgical procedures corresponding to that for DBS are extraordinarily efficient however they’re invasive and never everyone seems to be a candidate. Medicine corresponding to levodopa does not all the time curb tremors both.
“We do not have excellent management of tremors, so a noninvasive methodology can be very nice,” Tagliati mentioned. But it surely’s too early to say whether or not this gadget will fill this want. “Extra examine is required earlier than any conclusions could be drawn about this wearable gadget,” he added.
Be taught extra about managing tremors on the Parkinson’s Foundation.
