Vibrotactile Coordinated Reset Stimulation for the Therapy of Parkinson’s Disease: Theory and Clinical Results

Abnormally strong synchronization of neuronal activity is a hallmark of several brain disorders, such as Parkinson’s disease (PD). In PD patients, permanent high-frequency deep brain stimulation suppresses symptoms during stimulus delivery. A qualitatively different, theory-based approach uses dedicated patterns of electrical stimuli delivered to brain tissue to cause a desynchronization-induced decoupling of oscillatory neurons, intending to move neural networks from attractors with abnormal neural synchrony to more physiological (desynchronized) attractors. Corresponding cumulative and long-lasting therapeutic and desynchronizing effects were demonstrated in animal and clinical studies.

By replacing invasively delivered electrical bursts with non-invasively administered vibratory bursts, we have developed a non-invasive approach: Vibrotactile Coordinated Reset (vCR) stimulation delivered to the fingertips was designed to treat PD patients by inducing long-lasting desynchronization. In a feasibility study, six PD patients were treated with vCR stimulation delivered for four hours per day for three months. Patients’ conditions were evaluated after medication withdrawal (‘off medication’) by means of standard clinical scores and EEG recordings before and after the 3-month vCR treatment. In accordance with vCR-related computational studies, months-long vCR therapy causes a statistically and clinically significant reduction of PD symptoms off medication together with a significant reduction of high beta (21-30 Hz) power in the sensorimotor cortex. The ultimate goal of this approach is to induce sustained symptom relief by non-invasively delivering desynchronizing stimulus patterns only regularly or occasionally.


Remembering Frank Moss (1934-2011)

Frank Moss

The Center for Neurodynamics, the UMSL community, and many scientists throughout the world continue to mourn the loss of Frank Moss. January 4, 2021  marked the tenth anniversary of his death, and his friends and colleagues still find it difficult to wrap their minds around the idea that he is gone.

This past year has seen several international workshops held in Frank’s honor. A special Focus Issue of the journal Chaos appeared in December 2011, dedicated to Frank, and collecting a wide range of papers in the field of complex stochastic dynamics in biology, which he helped to found.
