Clinical Study On Lower Limb Robot For Lower Limb Dysfunction After Stroke

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical trial is to learn about effect of lower robot in stroke population. The main question[s] it aims to answer are: the efficacy of lower limb robot assisted training in improving walking ability, lower limb function, cognition, and quality of life in stroke patients.The robot group of patients received lower limb robot assisted training combined with routine rehabilitation treatment. The control group only received routine rehabilitation treatment.Compare two groups to explore the therapeutic effect of lower limb robots on lower limb dysfunction after stroke.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline Berg Balance Scale at 4 weeks | The Berg Balance Scale is a commonly used scale for evaluating balance ability in stroke Participants.Participants cooperate to complete the corresponding projects, and specialized assessors with professional knowledge in rehabilitation assessment will score based on the patient's completion status. The scale has a total of 14 items, including standing up from a sitting position, standing to sitting, standing independently, sitting independently, bed to wheelchair transfer, standing with eyes closed, standing with feet together, standing with upper limbs extended forward, standing with objects picked up from the ground, turning back to look, turning around for a week, alternating steps with both feet, standing with both feet in front of and behind, and standing with one leg. Each project has a maximum score of 4 and a ，minimum score of 0. The higher the score, the better the balance ability. | baseline and 4 weeks | 
| Change from Baseline functional ambulation category scale at 4 weeks | The functional ambulation category scale is a commonly used scale for evaluating walking ability, with ratings ranging from 0 to 5. The higher the level, the better the walking ability. | baseline and 4 weeks | 
| Change from Baseline fugl-meyer assessment-lower extremity at 4 weeks | The scale assesses the presence or absence of reflexes in the participants' lower limbs, as well as the presence of hyperreflexia, flexor coordination, extensor coordination, activities accompanied by coordination, activities without coordination, and speed.The higher the score, the better the lower limb motor ability | baseline and 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from Baseline modified barthel index at 4 weeks | The evaluators rated participants on items such as grooming, bathing, eating, toileting, dressing, bowel control, urination control, going up and down stairs, bed and chair transfer, and walking on level ground. The higher the score, the better the daily living ability. | baseline and 4 weeks | 
| Change from Baseline Gait parameters at 4 weeks | Use a gait analysis device to measure the patient's walking speed, stride frequency, stride length, and stride length. The linear distance traveled in the direction of travel per unit time during walking at a pace. Step frequency refers to the number of steps taken per minute during walking. Step length refers to the distance traveled by one foot following the ground during walking to the next foot following the ground. When walking, the distance traveled from one foot following the ground to another heel landing on that side. | baseline and 4 weeks | 
| Change from Baseline Minimum Mental State Examination at 4 weeks | This scale is a commonly used scale for evaluating participants' cognitive status. Participants are required to answer the corresponding questions or complete the corresponding actions according to the instructions. If the answer is correct or the corresponding actions are completed, 1 point will be awarded, otherwise no point will be awarded. The total score is 30 points, and the higher the score, the better the cognitive ability. | baseline and 4 weeks |
