Abstract: Objective To explore the feasibility of professional computer-aided design prosthetic software and processing systems for tele-process of lower-limb prosthesis. Methods The residual limb size data of 8 leg-amputation patients in prosthetic clinical reception were transferred to the computer prosthetic processing center. The appropriate lower-limb prosthetic socket mouth circles were selected in the software data model library, and were modified in accordance with the size table, and then they were processed and sent to the prosthetic clinical reception for the patients. The clinical function of lower-limb prosthesis was evaluated after try-on. Results The clinical function met the requirements in 7 patients wearing the prosthesis. Conclusion It is possible to design and tele-process lower-limb prosthesis through elaborate dimensional measurement, which can be a mode to serve lower-limb prosthesis to remote areas.
