In patients undergoing physical therapy after stroke, extracellular thiol-disulfide balance and intracellular oxidized-reduced glutathione balance levels will be monitored. The main objectives of this study are; (1) to determine the differences between thiol-disulfide and GSH-GSSG balances in stroke patients compared to healthy volunteers, (2) to evaluate the relationship of these balances with the severity of stroke, (3) to determine the predictive value of the levels of these balances on clinical prognosis and functional recovery outcomes, and (4) to investigate and to examine the effects of the physical therapy process on these parameters and functional recovery and their relationship with each other.

Stroke is among the most common causes of all deaths and Disability-Adjusted Life Years (DALYs) in the world. There is a close relationship between stroke pathophysiology and post-stroke clinic with oxidative stress. Thiol-disulfide homeostasis systems, which is one of the important extracellular and intracellular oxidative stress markers, showing antioxidant capacity with SH form, and oxidative status with disulfide (SS) form. In this study, we aimed to evaluate the relationship between the clinical outcome of subacute stroke patients and extracellular thiol-disulfide (SH-SS) and intracellular oxidized-reduced glutathione (GSSG-GSH) homeostasis and the comparison of these with healthy volunteers. In addition, the effect of the rehabilitation program on these oxidative stress markers and clinical scores and the predictive value of these oxidative stress parameters on prognosis were also evaluated. The main objectives of this study are; (1) to determine the differences between thiol-disulfide and GSH-GSSG balances in stroke patients compared to healthy volunteers, (2) to evaluate the relationship of these balances with the severity of stroke, (3) to determine the predictive value of the levels of these balances on clinical prognosis and functional recovery outcomes, and (4) to investigate and to examine the effects of the physical therapy process on these parameters and functional recovery and their relationship with each other. In this study, which is designed as a prospective observational study, patients with subacute stroke who have a stroke for the first time and are admitted to the hospital for the first rehabilitation treatment and healthy volunteers (control group) will be included. The clinical conditions of the patients will be evaluated at the beginning and after the 4-week rehabilitation program at the time of discharge by National Institutes of Health Stroke Scale Scores (NIHSS), modified Rankin Scale (mRS) and Barthel Daily Living Activities Index (BI). Serum and whole blood samples will be obtained from the patient group at the beginning and at discharge, and from the control group. The SH-SS homeostasis parameters (SH, Total SH, SS and SS / SH percent ratio) from serum samples and GSSG-GSH homeostasis parameters (GSH, Total GSH, GSSG and GSSG / GSH percentage ratio) from whole blood samples will be determined. Age, gender, hemiplegic side, type of stroke will be noted. Later, statistical analysis will be conducted.
