Brief Summary

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

This study will evaluate the effects of non-invasive stimulation of the spinal cord in people with spinal cord injury.

Detailed Description

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

This study will use a non-invasive form of spinal stimulation, called transvertebral direct current stimulation, or tvDCS. It currently is not clear what effects this type of stimulation has on the excitability of the brain and spinal cord in people with spinal cord injury. In this study, subjects will participate in 3 sessions, with at least 1 week in between sessions, during which they will get a different condition of tvDCS. We will test the excitability of the brain and spinal cord before and after tvDCS in each session.

Study Groups

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

Anodal tvDCS

20 minutes of anodal tvDCS will be applied over the spine at 2.5mA.

Group Type EXPERIMENTAL

transvertebral direct current stimulation (tvDCS)

Intervention Type DEVICE

tvDCS is a painless, non-invasive form of spinal stimulation which delivers safe, low levels of electrical current to the spinal cord through the back. It is believed to be able to influence the excitability of the brain and spinal cord.

Cathodal tvDCS

20 minutes of cathodal tvDCS will be applied over the spine at 2.5mA.

Group Type EXPERIMENTAL

transvertebral direct current stimulation (tvDCS)

Intervention Type DEVICE

tvDCS is a painless, non-invasive form of spinal stimulation which delivers safe, low levels of electrical current to the spinal cord through the back. It is believed to be able to influence the excitability of the brain and spinal cord.

Sham tvDCS

20 minutes of sham tvDCS will be applied over the spine.

Group Type SHAM_COMPARATOR

transvertebral direct current stimulation (tvDCS)

Intervention Type DEVICE

tvDCS is a painless, non-invasive form of spinal stimulation which delivers safe, low levels of electrical current to the spinal cord through the back. It is believed to be able to influence the excitability of the brain and spinal cord.
