The aim of this study was to investigate the effect of robot-assisted gait training on quadriceps muscle thickness, balance and gait parameters in individuals with chronic stroke. Stroke refers to a neurological disorder caused by cerebrovascular damage. It is defined as a sudden brain attack that causes partial or complete brain dysfunction due to blockage or rupture of blood vessels of the brain. The primary symptom of stroke is hemiparesis. In addition, stroke negatively affects senses, motor function, perception, cognition and language, depending on location, etiology and infarct volume. One study reported that 85% of stroke patients had hemiparesis and more than 69% had upper limb dysfunction. Balance and gait disturbances are closely related in chronic stroke patients; balance is an İmportant determinant of walking ability and motor function. Impairments in the strength and standing balance of the paretic lower limb are consistently associated with gait performance. Changes in segmental transverse range of motion and coordination are associated with poor gait and balance abilities \[5\]. Research has shown a continuous relationship between quadriceps muscle thickness and gait parameters in chronic stroke patients. Sánchez-Sánchez (2019) found that reduced quadriceps muscle thickness was associated with a lower ability to produce maximal force and postural instability, especially in those with limited mobility in the community. It was showed that fewer muscle modules, which may be indicative of reduced muscle thickness, were associated with poorer gait quality. A study found that decreased quadriceps muscle thickness and increased intramuscular fat were associated with decreased gait independence.These findings suggest that maintaining or improving quadriceps muscle thickness may be important in improving gait performance in chronic stroke patients. Robot-assisted gait training has been frequently used in research in recent years and positive improvements in gait speed and stride length have been obtained. In some studies, it has been shown that there is no significant difference in gait compared to traditional treatment, only improving clinical scales more . In contrast, Aprile (2017) found that both robotic and traditional gait training improved clinical scales, but only the robotic group showed higher percentage changes in certain scales.However, no significant difference was found in gait analysis. Ronchi (2015) also showed no additional gains in gait rehabilitation with robotic therapy compared to conventional treatment.Therefore, although robotic gait training offers some benefits, more research is needed to determine the different or similar effects on balance, gait and lower extremity muscle thickness compared to traditional methods. The aim of our study was to investigate the effect of robot-assisted gait training on quadriceps muscle thickness, balance and gait parameters in individuals with chronic stroke. The following hypotheses will be examined in the study. H0: Robot-assisted gait training has no effect on quadriceps muscle thickness, balance and gait parameters in individuals with chronic stroke. H1: Robot-assisted gait training has an effect on quadriceps muscle thickness, balance and gait parameters in individuals with chronic stroke

RECRUITINGFugl Meyer Lower Extremity Assessment:
In this scale, reflexes, synergy-dependent or independent voluntary movement, coordination and speed are evaluated, with each item scoring Yazım alanları gerektiği kadar uzatılabilir 2 points. 0: Cannot complete movement/No active movement. 1: Partial movement. 2: Movement is completed/movements can be performed normally. The lowest clinically significant score in the Fugl-Meyer test is considered to be 6
Time frame: 15 minutes
Ten meter walk test
For this test, a 16-meter walking track is created with starting and ending points and the test is completed without considering the first 3 and last 3 meters of this track. When the patient starts walking, the stopwatch is started after the first three meters and the stopwatch is stopped at the end of the tenth meter. After the patient walks the last 3 meters, walking is terminated. The completion time of the test is recorded in seconds
Time frame: 5 minutes
Berg Balance Scale
The Berg Balance Scale (BBS) is a scale that includes 14 instructions and for each instruction, the patient's performance is observed and a score between 0-4 is given. A score of 0 is given when the patient cannot perform the activity at all, while a score of 4 is given when the patient completes the activity independently. The highest score is 56, with 0-20 points indicating impaired balance, 21-40 points indicating acceptable balance, and 41-56 points indicating good balance. The scale takes between 10 and 20 minutes to complete. It has been validated in patients with chronic stroke
Time frame: 15 minutes
Examination of muscle thickness by ultrasound
The muscle thickness of the quadriceps and tibialis anterior muscles on the hemiplegic and intact side will be measured and recorded by ultrasound before and after treatment.
Time frame: 10 minutes
Gait Analysis with Kinovea
Walking distances of 3 meters will be recorded with the camera to be placed on the sagittal. Colored marks will be placed on the right and left heels. The colored marks will be marked on the video and step lengths, walking speed and arm swing will be calculated with Kinovea motion analysis software. Several gait cycles will be recorded in the video and cadence (number of steps per minute), right and left step lengths will be expressed
Time frame: 10 minutes
The Timed Up and Go Test
The Timed Up and Go Test is a simple, widely used and quick test to assess mobility, balance and fall risk. To perform the test, participants need to get up from a standard chair, walk comfortably to a location 3 meters away from the floor, turn around, walk back to the chair and sit down in the same chair. All steps of the test will be measured using a stopwatch
Time frame: 5 minutes
Stroke Specific Quality of Life Scale
This scale, which was created to assess the quality of life of people diagnosed with stroke, consists of 12 domains including 49 items and is scored with a five-point Likert scale. In determining the mean score of each domain of the scale, the scores obtained from all items belonging to the domain are summed and divided by the number of items belonging to the domain. The total score of the scale is calculated by dividing the sum of the average scores obtained from each domain by 12. A high scale score indicates a high quality of life
