Sistema de telerrehabilitación Guiado Por electrogoniometrÃa, lúdico y de Bajo Costo, Para la recuperación Funcional Posterior a Una Artroplastia de Rodilla en Personas Mayores
This study evaluated a wearable electrogoniometry-based telerehabilitation system designed to support recovery after total knee arthroplasty. Participants followed a home-based rehabilitation program, while patients in the intervention group additionally used a wearable knee device connected to a digital application that provided exercise guidance, real-time feedback, and remote monitoring. Knee range of motion, functional performance, and patient-reported outcomes were evaluated during postoperative recovery.
Participants were allocated sequentially in a non-randomized manner. The first 50 enrolled participants constituted the control group, and the subsequent 32 participants were allocated to the intervention group and received the wearable electrogoniometry-based telerehabilitation system. All participants underwent a preoperative baseline assessment. Following total knee arthroplasty, participants were followed weekly during the first 8 postoperative weeks, with a final assessment at 12 weeks. Clinical and functional outcomes included knee range of motion, functional performance, and self-reported assessments. Participants in the intervention group additionally completed a questionnaire evaluating the usability of and their experience with the technology-assisted rehabilitation system.
Inclusion Criteria:
Adults older than 60 years. Scheduled for primary total knee arthroplasty for knee osteoarthritis. Able to attend weekly postoperative range-of-motion assessments.
Exclusion Criteria:
Revision arthroplasty. Use of constrained implants. Cognitive impairment preventing adherence to rehabilitation instructions. Inability to participate in follow-up assessments.
