Study Evaluating Treatment of Upper Limb Spasticity Using the Cryo-Touch III Device

Upper Limb Spasticity Clinical Trial

Official title: A Prospective, Non-Randomized, Unblinded Study Evaluating the Treatment With the Cryo-Touch III Device for Upper Limb Spasticity

Status Completed

Clinical Trial Summary

A proof of concept study to evaluate the feasibility of safe and effective treatment of upper limb spasticity using the Cryo-Touch III Device.

Clinical Trial Description

Spasticity, common in neurological disorders, is part of the upper motor neuron syndrome displaying increased tone, clonus, spasms, spastic dystonia and co- contractions. The impact of spasticity on the patient varies from a subtle neurological sign to severe spasticity causing pain and contractures. Upper limb spasticity (ULS) is the rapid contraction or shortening of the muscles in the arm causing abnormal muscle movements in the elbow, wrist and fingers. It has been reported that over 1 million Americans with traumatic injury to the brain or spinal cord, stroke, multiple sclerosis and cerebral palsy experience ULS. Tightly clenched fists, twisted wrist and elbow joints, and fixed arms in flexed positions result in extreme discomfort, pain and spasm. A nonsurgical, minimally invasive, effective approach to pain associated with ULS is desirable.

Myoscience, Inc. (Redwood City, CA) has developed a pain management device - the Cryo-Touch III - for a novel, minimally invasive procedure using focused cold therapy to target sensory nerve tissue and offer long-lasting pain relief through cryoanalgesia. The device operates on the well-established cryobiology principle that localized exposure to controlled, moderately low temperature conditions can alter tissue function. The therapy treats nerves via a probe in the form of an assembly of small diameter needles, creating a highly localized, low temperature treatment zone around the probe. This focused cold therapy creates a conduction block that prevents nerve signaling. Prior studies of the Cryo-Touch, Cryo-Touch II, Cryo-Touch III (a.k.a. PCP 1.0) devices have provided preliminary evidence of effectiveness on motor nerves and have been shown to be safe with no serious device-related adverse events. ;
