Investigators found the objective functional impairment baseline severity stratification was a valid measure for patients with lumbar degenerative disc disease.
Researchers prospectively collected data for 375 consecutive patients who were scheduled to undergo lumbar surgery for degenerative disc disease. Investigators collected disease-specific parameters, VAS score for leg pain and back pain, Roland-Morris Disability Index (RMDI), Oswestry Disability Index (ODI) and health-related quality of life measures. The timed up-and-go test was conducted in a standardized manner, and investigators determined the objective functional impairment baseline severity stratification (OFI BSS).
Investigators noted there was a 0.53 increase in VAS back pain score, a 0.69 increase in VAS leg pain score, an increase of 1.81 points in the RMDI score and an increase of 5.93 points in the ODI score with each 1-step increase of the OFI BSS. There was also a decrease in the health-related quality of life with a -0.073 decrease in the EuroQol-5D, a -1.99 decrease in the SF-12 physical component summary score and a -1.62 decrease in the SF-12 mental component summary score.
According to researchers, there was an increase in leg pain among patients with mild OFI, moderate OFI and severe OFI by 0.9, 1.54 and 1.94 points, respectively, as well as an increase in ODI by 7.99, 12.64 and 17.13 points, respectively. There was a decrease in the SF-12 physical component summary score for patients with mild OFI, moderate OFI and severe OFI by -2.57, -3.63 and -6.23 points, respectively. – by Monica Jaramillo
