Brief Summary

In the literature, it has been observed that traditional balance training (TBT) and robot-assisted walking training (RAGT) in stroke patients stimulate the balance mechanism by supporting the spinal muscles symmetrically and functionally. However, it is seen that there is no clear protocol for RAGT in the chronic period. Combined RAGT and TBT approaches over ten weeks have been shown to be more effective than TBT alone for the acute and subacute period. However, there is no definite expression for chronic period effects. No study was found in the literature in which an objective measuring device was used for balance assessment of patients receiving TBT and RAGT. If changes are detected between the two treatment groups in balance education in stroke patients as a result of objective evaluation, our study will lead to the necessity of including these changes in the treatment. Considering the effect of balance on activities of daily living, we believe that objective evaluation of the changes in balance after TBT and RAGT in stroke patients and shaping the treatment according to the evaluation results will contribute to the literature.

Outcome Measures

Primary Outcomes (4)

• Berg Balance Scale

  It is used to evaluate postural control and to determine fall risk. It consists of 14 questions with parameters such as standing up from sitting, standing, transfers, taking a step, turning. A score of 0-4 is given for each question and the time the person performs the desired activity is recorded. At the end of the test, the total score received by the subject is calculated.

  5 weeks

• EncephaLog by Montfort® App

  The phone, which is fixed to the sternum of the participant, evaluates the static and dynamic balance with the integration of accelerometer and gyroscope. Static balance is evaluated in a neutral stance with feet open, feet together, feet together and eyes closed, in tandem stance for 10 seconds for each test. Starts the dynamic balance assessment with a 5 second countdown followed by a short audible tone and vibration. Participants stand up without any assistance or arm support and walk at their natural speed towards a cone positioned on the ground 3 m from their chair, then turn around the cone and walk back and sit. It provides objective data by recording the walking time and the test is repeated twice.

  5 weeks

• International Fall Efficiency Scale (FES-I)

  It was developed to assess the fear of falling. The cut-off point is 24 to distinguish between people who have a fear of falling and those who do not. The participant is asked to rate his/her concern about the possibility of falling while performing activities of daily living. Fear of falling is determined by adding the scores between 1-4 obtained from each question after completing 16 questions.

  5 weeks

• Timed Get Up and Go Test

  It is a measure for assessing balance and functional mobility. A chair and a stopwatch are required to administer the test. The shoes that are always used during the test are used and the test is continued with the assistive device if used. The person is asked to get up from a chair, walk 3 meters, turn around, walk back and sit, and the score is calculated by measuring how many seconds he or she completes the test. Completing the test in more than 12 seconds indicates that the risk of falling is high.

Study Arms (2)

Combined RAGT and TBT

EXPERIMENTAL

Participants will be treated with Lokomat for 40 minutes, twice a week for 5 weeks, and RAGT with a body weight support system and combined TBT for 40 minutes each session 3 times a week. During RAGT, 30-40% of each participant's body weight will be taken with the body weight support system. In patients without drop foot and knee instability in the sessions after the first session, the body weight will be reduced by 10% and progression will be achieved. The speed of the treadmill will be adjusted between 1.2-2.6 km/h and the maximum speed tolerated by the patient will be reached during the sessions. TBT exercises 3 times a week for 40 minutes (weight transfer to the paretic leg during sitting and standing, weight transfer during sitting and standing with or without an assistive device) will be personalized according to the patient. Progression of exercises will be provided by adding upper extremity and trunk activities in addition to exercises.

Other: Combined RAGT and TBT

TBT Only

ACTIVE COMPARATOR

Participants were given balance exercises (weight transfer to the paretic leg during sitting and standing, weight transfer during sitting and standing without an assistive device, walking on a flat surface to the forward and sideways) for 5 weeks, 5 times a week and for 40 minutes in each session. lying down while sitting and standing) will be applied.

Other: balance exercises
