Lumbar spinal stenosis (LSS) results in significant pain and disability. This paper proposes a new objective scoring system, the GPi, for LSS patients. Four key objective health metrics, which can be measured using wearable devices have been identified to correlate with health status: (I) step count; (II) gait velocity; (III) step length; (IV) posture. An algorithm combining these metrics was established to ‘score’ patient’s ambulation from 0 (bed bound)–100 (excellent mobility and gait function). 13 surgical patients were scored with GPi and compared with traditional subjective systems (ODI and PSI), showing similar preoperative and postoperative mobility. GPi provides a relevant measure of patient outcome and real-time recovery dynamics after LSS decompression.
