2012 – Self Reported Functional Limitations Due to Lumbar Stiffness Correlate with Age and SRS-22 Scores Among Asymptomatic Volunteers

May 7, 2013 by

Summary : The Lumbar Stiffness Disability Index (LSDI) was developed to track functional effects of spine stiffness. Normative data from asymptomatic volunteers demonstrates few stiffness related limitations. Advancing age is associated with an increase in LSDI scores. A significant correlation exists between LSDI scores and SRS-22 pain and function subscales, suggesting that perceived impacts of lumbar stiffness are related to impacts of low back pain.
