Virtual Reality Based Mirror Therapy

Fugl-Meyer Assessment

It is a scale based on measuring upper extremity performance in stroke patients. Test; reflex activity, flexor and extensor synergy, combined synergistic movements, non-synergy movements, normal reflex activity, wrist and hand evaluation, coordination and speed evaluation subsections. It consists of 33 items in total, and each item is scored between 0 and 2 points (0: unable, 1: partially able, 2: fully able). The total score is 66.

Evaluation of Cortical Activation with EEG

EEG signals will be recorded over the mu rhythm during rest and imagery tasks. Mu rhythm activity increases during rest and is suppressed during purposeful exercise or activity observation. This mu rhythm suppression is expressed as activation of relevant brain areas.

Motor Activity Log-28

It will be used to assess the spontaneous use of the hemiparetic limb in daily life. The MAG-28 is one of the commonly used assessment tools to assess activity according to the ICF. The MAG-28 consists of two scales and assesses the frequency of use and quality of movement of the affected upper extremity during 28 activities of daily living such as buttoning a shirt, opening a drawer, brushing teeth.In the scale, activity is scored between 0-5. A high score on the scale indicates that the frequency of upper limb use and quality of movement during activity is better.

Simulator Sickness Questionnaire

It has been widely used to assess various forms of illness triggered by virtual environments. It is constructed by transforming symptoms that participants subjectively report the presence and severity of on a scale. The Simulator Sickness Questionnaire assesses 16 symptoms such as eyestrain, nausea, sweating and headache on 4 different severity ratings (none, mild, moderate and severe). Higher scores indicate stronger beliefs about the underlying symptoms of illness. Military pilots with a total score above 20 are considered " poor-failure". The Virtual Reality Sickness Questionnaire, specifically developed to evaluate symptoms triggered by virtual environments. The questionnaire categorizes symptoms into two non-exclusive categories: general symptoms and ocular symptoms. Symptoms are rated on a scale of four severity levels (none, mild, moderate, and severe). A higher number of symptoms and total scores indicate lower tolerance to the virtual environment.

System Usability Scale

It consists of 10 statements that allow evaluating the ease of use (or lack thereof) of websites, software, hardware, mobile devices and other technological applications at a glance. Using a 5-point Likert scale, the SUS is basically a questionnaire for assessing usability and has Turkish validity. The average value of the SUS score is taken as 68, and an SUS score greater than 68 indicates that the system is above average, while a score below 68 indicates that the system is below average. The products with the highest usability ratings are classified as A+ and the percentage range is between 96-100.
