    Background: Measuring satisfaction with telerehabilitation provides a way to evaluate and improve the effectiveness of both the technology used and the rehabilitation provided. On the other hand, valid and reliable tools are needed to evaluate satisfaction of patients receiving physiotherapy via telerehabilitation. Aims: The purpose of the current study was to develop Telerehabilitation Satisfaction Questionnaire (TrSQ) and evaluate its validity and reliability. Methods: Sixty-three patients with stroke, Multiple Sclerosis, or Parkinson's disease participated in this study. Content validity was reviewed by a panel experienced in telerehabilitation. Construct validity of the model was investigated using and Confirmatory Factor Analysis (CFA) and Explanatory Factor Analysis (EFA). Test-retest reliability and Internal consistency were used to evaluate the reliability of the TrSQ. Results: A one-factor structure was determined based on EFA. The structure fitted well in terms of the fit indices according to the confirmatory factor analysis results (x2/df = 1.016, p = 0.442, IFI=0.997, CFI=0.997, and RMSEA=0.016). The questionnaire was proven to have an acceptable reliability level (Cronbach's alpha = 0.858) and it was found that all items were necessary. Finally, an 11-item version was obtained and tested twice on 30 patients. The questionnaire was shown to have acceptable test-retest reliability (ICC=0.753). Conclusions: TrSQ can be used as a valid and reliable questionnaire in evaluating patient satisfaction with telerehabilitation in neurological diseases. However, in order for it to be widely applicable, adaptation to different languages is needed.

    Development, Reliability, and Validity of the Telerehabilitation Usability Questionnaire in Neurological Diseases
    (Gumushane University, 2025) Eldemir, Kader; Eldemir, Sefa; Saygılı, Fettah; Özkul, Çağla; Kasikci, Merve; Gündüz, Arzu Güçlü
    The purpose was to develop Telerehabilitation Usability Questionnaire (TrUQ) and evaluate its validity and reliability in neurological diseases. Ninety-five people with Multiple Sclerosis, stroke, and Parkinson’s disease participated in this study. Content validity was assessed by an expert panel of 5 physiotherapist experienced in telerehabilitation. Construct validity was investigated using Confirmatory Factor Analysis (CFA) and Explanatory Factor Analysis (EFA). Test-retest reliability and Internal consistency were used to evaluate the reliability of the TrUQ. A three-factor structure was determined based on EFA. Accordingly, three factors correspond to three subscales, on the TrUQ: system availability, exercise feasibility, and telerehabilitation security. Furthermore, the model fits well according to CFA results: χ²/df = 1.573, CFI = 0.925, IFI = 0.929, GFI = 0.909, and RMSEA = 0.078. The questionnaire was proven to have an acceptable reliability level (Cronbach’s alpha= 0.712) and it was found that all items were necessary. Finally, a 10-item version was obtained, and TrUQ was shown to have acceptable test–retest reliability (ICC=645) TrUQ is a valid and reliable questionnaire can be used to measure usability of the telerehabilitation systems in neurological diseases. Adaptation to different languages and diseases is recommended to be widely applicable.
