| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Individualized stimulation group | Experimental | Based on transcranial direct current stimulation (tDCS) simulation, individualized stimulation on leg motor areas during 30 minutes. |
|
| Conventional stimulation group | Active Comparator | Conventional stimulation on leg motor areas during 30 minutes. |

|---|---|---|---|---|
| Individualized transcranial direct current stimulation | Device | Based on tDCS stimulation, individualized stimulation during 30 minutes with sitting position. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Changes in cortical activation | changes in cortical activation is measured by functional Near-Infrared-Spectroscopy (fNIRS) (NIRScout, NIRx, Germany) during treadmill gait. | Change from baseline (before stimulation) after stimulation during 30 min |
| Measure | Description | Time Frame |
|---|---|---|
| 10 meter walk test (10MWT) | Measure of self selected speeds by measuring the time it takes an individual to walk 10 meters. To perform the test, patient walks 10 meters (33 ft) and the time is measured when the leading foot crosses the start line and the finish line. The instructions are: "Please walk this distance at your normal pace when I say go." | Before stimulation (baseline); After strimulation during 30 min |

| Conventional transcranial direct current stimulation | Device | Conventional tDCS stimulation during 30 minutes with sitting position. |
|
| Timed Up and Go test (TUG) | The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. It uses the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. | Before stimulation (baseline); After strimulation during 30 min |
| Gait analysis using surface electromyograph | Gait analysis is a process of measuring and evaluating the walking patterns of patients by using surface electromyograph. | Before stimulation (baseline); After strimulation during 30 min |
| Gait analysis using motion analysis system | Gait analysis is a process of measuring and evaluating the walking patterns of patients by using motion analysis system. | Before stimulation (baseline); After strimulation during 30 min |
