Completed clinical trials

Feasibility Study of the MyoRegulator® Device to Treat ALS

PathMaker Neurosystems was the sponsor of the Feasibility Study of the MyoRegulator® Device to Treat ALS, a single-site US feasibility study funded by Muscular Dystrophy Association (MDA) that was a first-in-human trial evaluating the safety and feasibility of treatment using the MyoRegulator® device in people with amyotrophic lateral sclerosis (ALS). Results of this successful clinical trial are being presented at upcoming clinical conferences and are anticipated to be published in a forthcoming paper.

RECOVER Trial in Post-stroke Upper-Limb Spasticity

PathMaker Neurosystems was the sponsor of the RECOVER trial, a multi-center US pivotal trial funded by NIH that was evaluating treatment using the MyoRegulator® device in people with post-stroke upper-limb spasticity. The purpose of this study was to determine whether the treatment provided by the MyoRegulator® device for motor neuron hyperexcitability suppression can reduce chronic upper-limb spasticity following stroke. Results of this clinical trial are anticipated to be published in a forthcoming paper.

SPAST Trial in Post-stroke Lower-Limb Spasticity

The SPAST trial is the European pivotal trial that evaluated treatment using the MyoRegulator® device in people with post-stroke lower-limb spasticity. The SPAST trial was sponsored by France’s INSERM (Institut National de la Santé Et de la Recherche Médicale), and was conducted at the Paris Brain Institute (ICM). The purpose of this study was to evaluate the performance and safety of the treatment provided by the MyoRegulator® device for motor neuron hyperexcitability suppression in reducing chronic lower-limb spasticity following stroke. Results of this successful clinical trial are being published in a forthcoming paper.


Effect of Treatment with the MyoRegulator® Device in Patients with Severe Hand Spasticity after Stroke

A US single-site clinical study was conducted to evaluate treatment using the MyoRegulator® device in people with post-stroke upper-limb spasticity. The purpose of this study was to evaluate whether treatment provided by the MyoRegulator® device for motor neuron hyperexcitability suppression could significantly reduce spasticity of the wrist and hand following stroke. Results of this successful clinical trial have been published.
