Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A study to use transcutaneous spinal cord stimulation to characterize sensorimotor deficits in a pediatric population of individuals with spina bifida.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study's goals involve understanding how transcutaneous stimulation affects motor deficits across three dimensions; weakness, coordination, and spasticity. This will be investigated by an electrophysiological characterization lower-extremity deficits, using TS to interrogate neuromotor topography and connectivity of the spinal cord to specific muscles. These evaluations will enable a unique patient-specific understanding of the electrophysiological mechanisms underlying motor deficits. Furthermore, these evaluations will assess the therapeutic potential of a novel closed-loop TS plasticity induction protocol to strengthen weakened muscles in a pediatric SB population.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Functional motor training with transcutaneous spinal cord stimulation

Transcutaneous spinal cord stimulation will be delivered to the skin over the lower thoracic and lumbar spine region using adhesive electrodes for ages 5-11 for one multi-hour visit. The effects of stimulation will be recorded via electrophysiological and biomechanical metrics described within the outcomes measures.

Extended functional motor training with transcutaneous spinal cord stimulation

An extended functional training arm for a subset of 10 subjects, ages 12-18, in which they will receive up to twelve multi-hour sessions of a therapeutic neuromuscular strengthening intervention within a 6 week period.
