![]() ![]() ![]() The W6 responder status (clinically meaningful improvement) ranged between 81.3% (VAS leg pain) and 29.7% (EQ-5D index) of patients.CONCLUSIONSThe TUG test is a quick and easily applicable tool that reliably measures OFI in patients with LSS. The mean W6 OFI T-score was significantly decreased (103.1 ± 13.6 p < 0.001). At W6, 60 (93.8%) of 64 patients had a TUG test result within the normal population range (no OFI) 3 patients (4.7%) had mild and 1 patient (1.6%) severe OFI. The preoperative rates of severe, moderate, and mild OFI were 4.7% (n = 3), 12.5% (n = 8), and 7.8% (n = 5), respectively, and the mean OFI T-score was 116.3 ± 23.7. Preoperatively, they reported a mean VAS back pain score of 4.1 ± 2.7, VAS leg pain score of 5.4 ± 2.7, RMDI of 10.4 ± 5.3, ODI of 41.9 ± 16.2, SF-12 PCS score of 32.7 ± 8.3, and an EQ-5D index of 0.517 ± 0.226. Objective functional impairment (OFI) was measured using age- and sex-standardized TUG test results.RESULTSSixty-four patients (n = 32 male, mean age 66.8 ± 11.7 years) were included. The subjective functional status was estimated using PROMs for pain (visual analog scale ), disability (Roland-Morris Disability Index and Oswestry Disability Index ), and health-related quality of life (HRQoL 12-Item Short-Form Physical Component Summary and the EQ-5D) preoperatively, as well as on postoperative day 3 (D3) and week 6 (W6). Currently, only a few studies report pre- and postoperative TUG test assessments in patients with lumbar spinal stenosis (LSS).METHODSA prospective two-center database was reviewed to identify patients with LSS who underwent lumbar decompression with or without fusion. Subjective outcome measures are increasingly complemented by objective ones, such as the "Timed Up and Go" (TUG) test. ![]() OBJECTIVEPatient-reported outcome measures (PROMs) are standard of care for the assessment of functional impairment. ![]()
