Evaluating Face Validity and Patients' Comprehension of a Mobile Tele-Assessment Interface for Detecting Sensory Impairment in Dermatomal Segments Among Individuals with Spinal Cord Injury: A Semi-Structured Interview Study

This study assesses the face validity and patients’ understanding of a mobile tele-assessment interface designed to identify sensory impairments in dermatomal segments. Using a semi-structured interview methodology, qualitative data were collected from patients who interacted with the tele-assessment tool. The primary objectives were to evaluate patients’ comprehension and usability experiences. Participants provided insights into the ease of use, clarity of instructions, and overall satisfaction with the mobile interface. Results indicate that the tele-assessment tool is perceived as an alternative and user-friendly method for remote sensory evaluation, with potential to improve patient care, particularly in underserved or remote areas. Suggestions for enhancing the interface and recommendations for broader implementation are discussed. This research adds to the expanding field of telemedicine and mobile health technologies, emphasizing the importance of patient-centered design in creating effective digital health solutions.
