General cognitive level will be evaluated with the Standardized Mini Mental Test to determine the eligibility of the participants for the study. The American National Institutes of Health Stroke Scale will be applied to determine the stroke severity and functional status of the participants. The reliability and validity of the eight-shape gait test and the double-task octagonal gait test will be examined. The reliability of the tests will be evaluated by calculating the test-retest method, standard error measurement and minimum detectable change values. The initial test and retest will be evaluated two days apart. The concurrent validity of the tests will be evaluated by the correlation between the timed get-and-go test, the 10-meter walk test, and the modified four-square step test.

The Standardized Mini Mental Test, The American National Institutes of Health Stroke Scale, the Figure of 8 Walk Test, the double-task octagonal gait test, the timed up-and-go test, the 10-meter walk test, and the modified four-square step test will be applied to the stroke patients.

It is a practical, short and standardized test that evaluates cognition in general. It consists of five subsections and 11 items: orientation, recording memory, attention and calculation, recall and language. A total of 30 points can be obtained from the test. Scores below the 23/24 threshold for the Turkish population indicate dementia (Güngen, Ertan, Eker, Yaşar, & Engin, 2002).

The scale used to determine the severity of stroke consists of a total of 11 items. The highest score of the scale is 36. On the scale, >17 points are severe, 8-16 points are moderate, and <8 points indicate mild stroke (Brott et al., 1989).

Participants will be instructed to stand in the middle of two cones 1.52 m apart and walk around the cones at their normal walking pace, in the direction of their choice, in a figure eight, and stop when they reach the starting point. The time to complete the test will be recorded. The original F8W test also takes into account the number of steps and gait smoothness required to complete the task (Hess et al., 2010). Only the time to complete F8W will be used in this study, as time is more objective than smoothness and number of steps in evaluating changes in walking performance.

It is a valid and reliable tool that evaluates walking performance on flat roads in stroke individuals. The time it takes for an individual to complete 10 meters at normal walking speed at a distance of 14 m (the first and last 2 m distances are not considered) is recorded (Cheng, Nelson, Brooks, & Salbach, 2020).
