The Effect of Robot-assisted Walking Training on Hemiplegic Individuals
Study Details
Study Description
Brief Summary
The aim of this study is to compare the effects of robotic rehabilitation on balance, body control, mobility, spasticity, motor function and depression compared to traditional therapy in individuals with chronic stroke. Patients aged between 40-70 years, who applied to the Private Avrasya Hospital Physical Therapy and Rehabilitation Clinic, were diagnosed with hemiplegia based on an epicrisis medical board report, were included in the study on a voluntary basis, regardless of gender. After recording the demographic and clinical information of the participants, based on the physician's decision, they were included in 2 groups: conventional treatment combined with robotic rehabilitation (n=20) and conventional treatment only (n=20).
While one of the groups received traditional treatment, the other group received robotic walking training in addition to conventional treatment. Traditional treatment includes strengthening, balance, range of motion exercises and gait training applied 3 days a week for 4 weeks. Robot-assisted walking training was planned for 20 minutes, 3 days a week.
As assessment methods, number of steps, the 10m Walk Test, Brunnstrom motor staging, Functional Ambulation Classification, Fugl Meyer Rating Scale (lower extremity section), Modified Ashworth Scale, Beck Depression Scale, Tinetti Balance and Gait Test, Postural Assessment Scale in Stroke Patients and Stroke Impact Scale were used. Gender, age and duration of illness showed homogeneous distribution between the groups.

Detailed Description
More than 80% of stroke survivors have impaired walking ability, but most regain their ability to walk. While 40% of them need help while walking, 60% of the group do not have the ability to move independently outside the home. Balance disorder is the most common problem after stroke. Decreased muscle strength and joint range of motion and impaired coordination and sensory organization mechanism prevent balance. 80% of individuals who have had a stroke for the first time have balance disorder in the subacute phase. As a result of restricted balance, postural control deteriorates, the risk of falling increases and mobility decreases.
Interventions to improve gait function should be intense, repetitive, and task-oriented. Intensive efforts of more than one physiotherapist are required in patients who do not have independent gait. Robot assisted walking devices; provides high-intensity, repetitive, task-specific therapy. It both reduces the workload of physiotherapists and improves gait quality, functional results (walking speed and capacity) and motor performance with multi-sensory stimulation.

Outcome Measures
Primary Outcome Measures
- The 10-meter walking test [0-4 weeks]
The 10-meter walking test will be performed in the 16-meter walking area without looking at the first and last 3 meters. The stopwatch will be started after the patient walks for the first 3 meters and the time will be stopped after the 10 meters are completed. The time to complete the 10 meters will be determined in seconds.
- Number of Steps [0-4 weeks]
Calculation of the number of steps in one minute.
- The Fugl Meyer Rating Scale [0-4 weeks]
The Fugl Meyer Rating Scale is a scale used to evaluate sensorimotor impairment in individuals with stroke. The maximum score is 226, which corresponds to full sensory-motor recovery. It is an ordinal scale with 3 points for each item. A given task is given 0 points if it cannot be done, 1 point if it is partially done, and 2 points if it is done completely. Reflex activity is measured using only 2 points, 0 points are given if there is no reflex, and 2 points are given if there is. In the study, the 34-point part of the scale for the lower extremity will used.
- The Postural Rating Scale in Stroke Patients [0-4 weeks]
The Postural Rating Scale for Stroke Patients (PASS-Turk) will be used to assess trunk control. This scale helps to predict prognosis, shape treatment, and monitor time-dependent improvement. It is advantageous in that it is comprehensive, sensitive in evaluating changes in patients, and can be used even in patients with low physical capacity. The scale consists of 12 questions and each question is scored between 0-3 (0 = unable to do, 3 = able to do without assistance).
- Tineti Balance and Gait Assessment [0-4 weeks]
The scale consists of 2 subtests: the first 9 questions are about balance and the next 7 questions are about walking. In 16 questions, the movements during ADL are questioned. If the movement is done correctly, 2 points are given, if the movement is made with adaptations, 1 point is given, if it cannot be done, 0 points are given. If the total score is 18 and below, the risk of falling is high, if it is 19-24, the risk of falling is moderate, and if it is 24 and above, the risk of falling is high.
- The Stroke Impact Scale [0-4 weeks]
The Stroke Impact Scale will be used as a stroke-specific health status measure in the assessment of quality of life. It consists of a total of 59 items and 8 subsections: strength, hand function, activities of daily living, mobility, communication, emotion, memory and thinking, participation. If the patient cannot complete the item, he will be asked to give 1 point, if he has no difficulty in completing it, he will be asked to give 5 points. At the end of the scale, the visual analog scale (0: No recovery, 100: Complete recovery) will evaluate the perception of general recovery after stroke.
- Brunnstrom motor staging [0-4 weeks]
Brunnstrom motor staging is a test that measures motor progress in parts of the central nervous system that regulate motor performance in patients with hemiplegia. The degree of recovery of the central nervous system is evaluated by enabling the patient to perform selected motor actions that require progressively better neuromuscular control. There are 6 stages for the lower extremity
- Functional Ambulation Scale [0-4 weeks]
The amount of physical support that patients need during walking will be determined by the Functional Ambulation Scale. Evaluation is made out of 6 points between 0-5 (0=Cannot ambulatory alone, 5=Can walk independently on all kinds of surfaces).
- The Modified Ashworth Scale [0-4 weeks]
The Modified Ashworth Scale is the most commonly used assessment method for spasticity in the international arena (10). The patient is examined in a supine and relaxed position. The joint is moved passively, repetitively and rapidly, and is scored between 0 and 4 according to the resistance of the joint to movement (0 = no increase in tone, 4 = the affected extremity is rigid in flexion and extension).
- Beck Depression Scale [0-4 weeks]
Emotional symptoms such as hopelessness and guilt and physical symptoms such as weight loss, fatigue and insomnia are also examined in the questions in the scale. There are 21 questions, points are given between 0-3. According to the total score, it is evaluated as follows: 0 to 9 points = minimal depressive symptoms, 10 to 16 points = mild depressive symptoms, 17 to 29 points = moderate depressive symptoms, 30 to 63 points = severe depressive symptoms .
