About

This study was conducted in patients with ischemic stroke; This study was conducted to examine the effect of robotic rehabilitation and transcutaneous auricular vagal nerve stimulation applied in addition to robotic rehabilitation on the patient's functional level and autonomic nervous system.

40 people over the age of 18 participated in the study. They were randomly divided into two groups: robotic rehabilitation and transcutaneous auricular vagal nerve stimulation applied in addition to robotic rehabilitation. While the robotic rehabilitation group received Lokomat and neurological rehabilitation, the other group received stimulation with the Vagustim device, which is applied non-invasively through the ear, in addition to Lokomat and neurological rehabilitation. Spasticity, autonomic nervous system, walking speed, motor function, quality of life, muscle activity and pain were evaluated in both groups before starting treatment and six weeks after treatment. In the study, significance was evaluated at p<0.05 level.

Full description

A study group was formed, consisting of individuals who had an ischemic stroke over the age of 18, who complied with the research criteria and who signed the voluntary consent form. Age, gender, height, weight, body mass index, dominant side, affected side and time since stroke of the participants who met the inclusion criteria were recorded and randomly divided into 2 groups.

The groups are; They were divided into Robotic Rehabilitation (RRG) (n=20, 11 women, 9 men) and Transcutaneous Auricular Vagal Nerve Stimulation (VRRG) applied in addition to Robotic Rehabilitation (n=20, 9 women, 11 men) groups.

A 6-week protocol was applied in the study. In addition to the neurological rehabilitation program, robotic rehabilitation was applied to the RRG group 2 days a week. In addition to the neurological rehabilitation program, both robotic rehabilitation and transcutaneous auricular vagal nerve stimulation were applied to the VRRG group 2 days a week. Some evaluations were made by the researcher at two different time periods throughout the study. Evaluation times; T0 (before robotic rehabilitation/vagal nerve stimulation application in addition to robotic rehabilitation), T1 (robotic rehabilitation/after vagal nerve stimulation application applied in addition to robotic rehabilitation). These time periods were planned and carried out immediately before the study and after 6 weeks of treatment.

40 participants in 2 patient groups

Robotic Rehabilitation Group (RRG)

Experimental group

Description:

A 6-week protocol will be applied in the study. In addition to the neurological rehabilitation program, robotic rehabilitation will be applied to the RRG group 2 days a week. Some evaluations will be made by the researcher at two different time periods throughout the study. These time periods will be planned and carried out immediately before the study and after the 6-week treatment.

Treatment:

Device: Robotic Rehabilitation

Vagal Nerve Stimulation With Robotic Rehabilitation Group (VRRG)

Experimental group

Description:

In addition to the neurological rehabilitation program, the VRRG group will receive both robotic rehabilitation and t-VNS 2 days a week. Some evaluations will be made by the researcher at two different time periods throughout the study. These time periods will be planned and carried out immediately before the study and after the 6-week treatment.
