ABSTRACT
OBJECTIVE: Patient-reported outcome measures (PROMs) are traditionally used to track patients’ recoveries after spine surgery. Wearable accelerometers have adjunctive value because of the continuous, granular, and objective data they provide. We conducted a prospective study of lumbar laminectomy patients to 1) determine if time-series data from wearable accelerometers could delineate phases of recovery and 2) compare accelerometry data to PROMs during recovery tracking.
METHODS: We prospectively recruited lumbar stenosis patients indicated for lumbar laminectomy. Subjects wore accelerometers that recorded their daily step counts from at least 1 week preoperatively to 6 months postoperatively. Subjects completed the Oswestry Disability Index (ODI) and the 12-Item Short Form Survey (SF-12) preoperatively and at 2 weeks, 1, 3, and 6 months postoperatively. Daily aggregate median steps (AMS) and individual visit-specific median steps (VSMS) were calculated. The Pruned Linear Exact Time method was used to segment AMS into distinct phases. Associations between VSMS and PROMs were identified using Spearman rank correlation testing.
RESULTS: Segmentation analysis revealed three distinct postoperative phases: step counts rapidly increased for the first 40 days postoperatively (acute healing), then gained more slowly for the next 90 days (recovery), and finally plateaued at preoperative levels (stabilization). VSMS was significantly correlated with PROMs throughout the postoperative period. However, PROMs significantly exceeded baseline at 6 months postoperatively while step counts did not (all p < 0.05).
CONCLUSION: Continuous data from accelerometers allowed for identification of 3 distinct stages of the postoperative period after lumbar laminectomy. PROMs remain necessary to capture subjective elements of recovery.
