As part of our ongoing commitment to finding innovative treatments for Parkinson’s disease (PD), we are conducting a Phase 1 clinical trial in Orlando, Florida, aimed at evaluating how Whole-Body Neuromuscular Electrical Stimulation (WB-NMES) combined with exercise can reduce tremors and improve motor function. This trial seeks to provide a non-invasive, non-medication-based approach to addressing the debilitating symptoms of PD.

Parkinson’s Disease: Understanding the Mechanisms

Parkinson’s disease is characterized by the loss of dopamine-producing neurons in the brain, particularly in the substantia nigra, which plays a crucial role in regulating movement. Dopamine is a neurotransmitter responsible for transmitting signals between the brain and muscles, enabling smooth and coordinated movement. As dopamine levels decline, the brain’s ability to control motor functions diminishes, resulting in symptoms such as tremors, muscle stiffness, and slowed movement.

Tremors arise from abnormal electrical activity in the brain’s motor circuits. When these circuits are overactive, they cause unintended muscle contractions, leading to the characteristic shaking observed in Parkinson’s patients.

Leveraging Exercise and WB-NMES to Influence Chemical and Neural Changes

Exercise has long been recognized for its benefits in managing Parkinson’s symptoms. It promotes dopamine release and enhances neuroplasticity, which is the brain’s ability to form new neural connections and repair damaged ones. Neuroplasticity is critical in PD treatment because it allows the brain to compensate for the loss of dopamine-producing neurons, potentially improving motor function and reducing the intensity of symptoms like tremors.

WB-NMES builds on this by directly stimulating muscles through electrical impulses, triggering contractions that are beyond what the patient could voluntarily achieve. This stimulation not only strengthens muscles but also sends signals back to the brain, which further enhances neuroplasticity. The muscle contractions induced by WB-NMES mimic the effects of intense exercise without requiring the physical exertion typically needed. This feedback loop is crucial: as the muscles contract, the brain adapts, potentially reorganizing neural pathways and reducing the abnormal electrical oscillations that cause tremors.

The combination of exercise and WB-NMES amplifies these effects. Chemical changes occur in the brain following WB-NMES-assisted exercise, including increased production of neurotrophic factors like BDNF (Brain-Derived Neurotrophic Factor), which are critical for promoting neural growth and synaptic plasticity. These factors help the brain improve its dopaminergic efficiency, meaning that even with lower dopamine levels, the brain can use the available dopamine more effectively to control movement. This adaptation may lead to fewer and less intense tremor episodes over time.

Neuroplasticity: Rewiring the Brain to Reduce Tremors

Neuroplasticity is at the heart of why our WB-NMES protocol holds so much promise. By consistently engaging the brain and muscles through forced exercise and electrical stimulation, we aim to retrain the motor circuits responsible for movement. As the brain adapts to the signals sent by the stimulated muscles, it can begin to suppress the abnormal oscillations that cause tremors, leading to an overall reduction in their frequency and intensity.

Studies show that forced exercise—exercise that pushes the body beyond its voluntary capacity—has a profound impact on dopamine regulation and neuroplasticity in Parkinson’s patients. WB-NMES acts as a facilitator of forced exercise by driving involuntary muscle contractions, creating an environment where the brain can recalibrate its control over motor functions. This dual mechanism of enhancing both muscular strength and brain plasticity offers a holistic approach to treating Parkinson’s symptoms, particularly tremors.

Our Phase 1 Trial in Orlando

In our ongoing Phase 1 clinical trial, Parkinson’s patients are undergoing a 12-week program that combines WB-NMES with exercise, receiving three 20-minute sessions per week. This approach not only aims to strengthen muscles but also to promote lasting changes in brain function through neuroplasticity.

Metrics of Success

To ensure a comprehensive understanding of the effects of this protocol, we are utilizing several objective measures:

• Accelerometry-based tremor measurements to track changes in tremor frequency and intensity.
• DEXA scans to monitor changes in muscle mass and body composition.
• Unified Parkinson’s Disease Rating Scale (UPDRS) to evaluate both motor and non-motor symptoms.
• Patient-reported outcomes (PROs) to assess improvements in daily function and quality of life.

Through these metrics, we aim to validate that WB-NMES, when combined with exercise, can significantly improve motor function and reduce the occurrence and intensity of tremors in Parkinson’s patients.
