Objective : The study examined the validity and reliability of tele-assessment of cervical range of motion (ROM) through video conferencing.
Design : A cross-sectional study
Methods : The study included 22 healthy adults as subjects and 10 physical therapists as evaluators. The subjects underwent both face-to-face and tele-assessment of cervical ROM. The CROM (Cervical Range of Motion) device was used for reference measurements in the face-to-face assessment. The evaluators assessed the subjects' ROM through visual inspection (VI) and using a Universal Goniometer (UG) in the tele-assessment.
Results : The results showed a significant correlation between the face-to-face and tele-assessment measurements for all ROM contents. The correlation coefficients ranged from r＝0.54 to 0.71 (p<0.05), indicating concurrent validity. In terms of inter-rater reliability, the ICC values for both VI and UG assessments in the tele-assessment were high, with ICCs of 0.93 and 0.92, respectively. Additionally, the study investigated the usability of the tele-assessment method and environment. The satisfaction of the participants and evaluators was assessed using the Telehealth Usability Questionnaire (TUQ), which evaluates perceptions, usability, and satisfaction with telehealth services.
Conclusions : In conclusion, tele-assessment of cervical range of motion using video conferencing was valid and reliable. Also, investigated participant and evaluator satisfaction and opinions, providing insights into the clinical value of tele-assessment. It is important to note that the study was conducted only healthy adults, and further research may be needed to validate the tele-assessment method in populations with cervical dysfunction or neck pain. These findings support the potential effectiveness of telerehabilitation services in assessing and managing musculoskeletal disorders.
