Low-bandwidth telemedicine for remote orthotic assessment.
A model for performing remote orthotic assessments using low-bandwidth computer communication technology (video conferencing) was developed, tested, and evaluated. System evaluation involved comparing a series of remote assessments with on-site assessments. While most on-site and on-line results were similar, discrepancies which occurred were attributed to between-clinician differences, measurement technique differences, technical and learning obstacles at the start of the project, and within subject variations during the day. On-line assessment efficiency improved with each on-line session and corresponded with increased confidence in the system, easier system use, and better overall satisfaction. An on-line debriefing session was held with all project clinicians. These clinicians supported continued use of the communication system for rehabilitation consultation and education. Clinically. preliminary face-to-face meetings and a regular practice schedule were recommended. Technically, the system was considered good; however, suggested improvements included using a high quality speaker-phone system, streamlining the video capture process, and providing more reliable telecommunication connections.
