Wearable Systems for Posture Monitoring and Spine Rehabilitation

Wearable technologies have emerged as a transformative approach to the assessment and management of spinal health, combining miniaturised sensors, data processing algorithms and user feedback mechanisms to deliver continuous, non-invasive monitoring of posture and rehabilitative progress. By integrating inertial, magnetic or optical sensing modalities into garments, braces or standalone devices, these systems capture biomechanical parameters such as segmental angles, curvature indices and dynamic range of motion in real time. Advanced signal-processing methods, including machine learning techniques, enable automated classification of fault postures and early detection of maladaptive movement patterns. Beyond mere monitoring, novel actuated solutions provide corrective forces or haptic cues to facilitate active rehabilitation and habit retraining. Collectively, these wearable platforms offer the potential to bridge the gap between clinic and daily life by delivering objective, quantitative assessments outside specialised environments, personalising therapeutic regimens, enhancing patient engagement and reducing reliance on intermittent imaging or laboratory-based motion capture. As low-cost manufacturing and wireless communication continue to advance, such systems are poised to play a central role in preventive strategies, postoperative rehabilitation and long-term management of common spinal disorders on a global scale.
