Objective measurement of free-living physical activity (performance) in lumbar spinal stenosis: are physical activity guidelines being met?

摘要: Abstract Background Research suggests that people with lumbar spinal stenosis (LSS) would benefit from increased physical activity. Yet, to date, we do not have disease-specific activity guidelines for LSS, and the nature of free-living (performance) in LSS remains unknown. care providers could endorse 2008 United States Physical Activity Guidelines; however, know if this is realistic. The goal present study was determine proportion individuals meeting Guidelines. A secondary better understand performance population. Study Design Retrospective study. Patient Sample People Lumbar Spinal Stenosis Accelerometry Database, all whom both radiographic clinical are seeking various treatments their symptoms. Outcome Measures Seven-day accelerometry (functional outcome) demographics (self-reported). Methods For study, analyzed only baseline data were obtained before any new treatments. Patients at least 4 valid days included. We determined US Guidelines 150 minutes moderate-vigorous (MV) per week bouts 10 or more. also used novel Performance analysis designed by our group time spent varying intensities There no conflicts interest disclose. Results 75 a mean age 68 (SD 9), 37% male. Three (4%) considered Meeting (at MV minutes/week), 56 (75%) Inactive even 1 minute/week. With 10-minute bout requirement removed, (13%) achieved 150-minute threshold. average sedentary 82%, nonsedentary activity, 99.6% light range. Conclusions In conclusion, confirms symptomatic neurogenic claudication, walking limitations, LSS-related disability extremely an urgent need interventions aimed reducing behavior increasing overall level improve function but prevent diseases inactivity. time, intensity higher may be appropriate as initial goals exercise transitioning moderate when appropriate. demonstrate importance employing measures assessment highlight potential value these methods developing targeted realistic personalized using objective accelerometry. one step toward medicine approach focusing on function.
