Brief Summary

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

The overall goal of the proposed project is to perform a preliminary study to assess the potential effects of galvanic vestibular stimulation (GVS) on the outcomes of a cognitive test of attention and the outcomes of robot-assisted upper-limb rehabilitation.

Detailed Description

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

We plan to explore the use of GVS on the severity of attention span deficits and motor training delivered using a spring-based robot. We intend to carry out the study in a small cohort of traumatic brain injury (TBI) survivors (20 subjects). Subjects with attention span deficits but no significant motor impairments will solely undergo a cognitive test of attention with/without GVS. Subjects with both attention span deficits and significant motor impairments will undergo a cognitive test of attention and robot-assisted upper-limb rehabilitation with/without GVS.

Study Groups

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

Cognitive test with/without GVS

Subjects with attention span deficits and no significant motor impairments undergo solely a cognitive test. The test is carried out in multiple trials. For some of the trials (randomly selected), subjects receive galvanic vestibular stimulation (GVS). For other trials, subjects received sham GVS. GVS is delivered using a device by A-M Systems.

Group Type EXPERIMENTAL

GVS

Intervention Type DEVICE

A small current is delivered to the vestibular system via electrodes placed over the subject's mastoid processes.

Sham GVS

Intervention Type DEVICE

Electrodes are placed over the subject's mastoid processes and connected to the device, but the device is not active.

Armeo Spring +GVS

Subjects with both attention span deficits and significant motor impairments undergo robot-assisted upper-limb rehabilitation in combination with galvanic vestibular stimulation (GVS). Robot-assisted training is carried out using the Armeo Spring system by Hocoma AG. GVS is delivered using a device by A-M Systems.

Group Type ACTIVE_COMPARATOR

GVS

Intervention Type DEVICE

A small current is delivered to the vestibular system via electrodes placed over the subject's mastoid processes.

Armeo Spring

Intervention Type DEVICE

A robotic system supports the weak arm of the subject to make it easier to perform therapeutic exercises.

Armeo Spring + sham GVS

Subjects with both attention span deficits and significant motor impairments undergo robot-assisted upper-limb rehabilitation in combination with sham GVS. Robot-assisted training is carried out using the Armeo Spring system by Hocoma AG. Sham stimulation is delivered by connecting the subject to a device by A-M Systems, but the device is not active.

Group Type SHAM_COMPARATOR

Sham GVS

Intervention Type DEVICE

Electrodes are placed over the subject's mastoid processes and connected to the device, but the device is not active.

Armeo Spring

Intervention Type DEVICE

A robotic system supports the weak arm of the subject to make it easier to perform therapeutic exercises.
