Questionnaire items will be created in two stages. First, 5 experts will independently review the literature on "telerehabilitation" and "usability". In addition, these experts will be asked to create a pool of questions based on their experiences in telerehabilitation and by taking the opinions of patients receiving telerehabilitation about usability. Then, 5 experts will come together and obtain a single question pool containing the questions they deem important in their question pool. The second step will involve scaling the elements. In this study, scale items will be scored on a five-point Likert scale, ranging from 1, strongly disagree to 5, strongly agree. Then, it will be applied to a pilot group of 10 people and it will be evaluated whether the items prepared by the experts are understood by the patients. In line with the expert opinion and the result of the pilot study, the final version of the scale will be decided and applied to MS, PD, and stroke patients who make up the study group. Finally, the validity and reliability of the questionnaire will be calculated.
