The Effect of Robotic Rehabilitation in Stroke Patients

The Fugl-Meyer Motor Assessment Scale reflects the stages of motor development. Each item in the assessment is scored out of 2 points. Each parameter is scored as follows: 0: Failure, 1: Partially successful performance, 2: Completely successful performance. The maximum achievable upper extremity motor performance score is 66 points. In upper extremity assessment, 53-66 points indicate full capacity, 48-52 points indicate sufficient capacity, 32-47 points indicate limited capacity, and 31 points and below indicate poor capacity. The Fugl-Meyer Motor Assessment Scale (FMAS) evaluates upper extremity motor function totals 66 points, with a maximum of 36 points for the upper arm, 10 points for the wrist, 14 points for the hand, and 6 points for coordination. A high score indicates good motor function. In our study, only the FMAS upper extremity motor function score was used to evaluate upper extremity motor functions.

This is a test that evaluates the motor development of hemiplegic individuals. In this test, the recovery process of a hemiplegic individual is defined in six stages. According to this staging, the lowest stage is stage I (flaccid, lack of voluntary movement), and the highest stage is stage VI (isolated joint movement). The upper extremity, lower extremity, and hand are evaluated separately. Higher Brunnstrom stages indicate better motor development.

Muscle tone was assessed using the Modified Ashworth Scale (MAS). MAS is an updated version of the Ashworth Scale, first described by Ashworth in 1964 to measure the increase in muscle tone. This scale evaluates the resistance during passive movement of an extremity on a scale of 6 points (0, 1, 1+, 2, 3, 4) from 0 to 4. Although its validity and reliability are debated due to the lack of guidelines regarding positioning and application, MAS is widely used today in the assessment of spasticity because it does not require any tools and is easy to apply. The tone of the shoulder flexor and adductor, elbow flexor, wrist, and finger flexor muscles in the upper extremity of the individuals included in the study was assessed according to their MAS. All muscle groups were scored according to their MAS after a single, rapid, passive stretch, starting from their shortest position.

It uses numerical rating scales from 0 to 10. The BPI scale defines pain as follows: 1 - 4 = Mild Pain, 5 - 6 = Moderate Pain, 7 - 10 = Severe Pain.

Since pain can vary significantly throughout the day, the BPI asks patients to rate their pain at the time they respond to the questionnaire. In addition, the questionnaire asks the participant to indicate the worst, least, and average pain in the previous week. "0 = no interference; 10 = completely interferes". The BPI evaluates pain by dividing it into 2 subheadings: pain intensity and interference of pain with daily functioning. Pain intensity is calculated by averaging the worst, least, average, and current pain scores, which are queried between items 3 and 6. Interference of pain with daily functioning is calculated by averaging 7 items that assess interference with general activity, mood, walking ability, normal work, relationships, sleep, and enjoyment of life. In the study, patients were questioned about shoulder pain.

MoCA was developed as a rapid screening test for mild cognitive impairment. MoCA assesses various cognitive functions, including attention and concentration, executive functions, memory, language, visualization skills, abstract thinking, calculation, and orientation. The MoCA takes approximately 10 minutes to administer. The maximum possible total score is 30. Therefore, a score of 21 or higher is considered normal.

This is a palpation technique used by clinicians to determine whether shoulder subluxation is actually present. The space between the acromion and the humeral head is palpated to determine how many finger widths can fit into it. The number of fingers is related to a subluxation grading system. The grading increases with the amount of subluxation.

A 0-5 grading scheme is used:

0: No subluxation

• ½ finger width space
• 1 finger width space
• 1½ finger width space
• 2 finger width space
• 2½ finger width space

This scale helps identify and classify cognitive and motor disabilities, and determines independence in daily life. It is a measure that assesses a person's performance in daily living activities. It consists of two sections: motor function and cognitive function. Items are scored from 1 to 7 (1 = full assistance, 7 = full independence). The total score ranges from 18 to 126. A score of 18 indicates complete dependence, while a score of 126 indicates complete independence.

Through a demographic information form, participants' gender, age, height, body weight, body mass index, education level, employment status, occupation, marital status, number of children, dominant hand, smoking and alcohol use, contact information, chronic diseases, medication use, psychological disorders, and stroke-related information such as date of stroke, date of hospitalization, side of the body affected by the stroke, type of stroke, and assistive devices used were recorded.
