Older adults with concurrent low back and hip pain are predisposed to reductions in physical performance and health-related quality of life. The objective of this study was to determine if hip osteoarthritis (OA) signs and symptoms per American College of Rheumatology (ACR) criteria are associated with fall risk over a 1-year span.

Falls were prospectively monitored for 1 year via fall calendars. Age, sex, body mass index (BMI), anxiolytic use, balance confidence, LBP-related disability, and prior fall history were identified as covariates. Hip pain, pain with hip internal rotation (IR), hip IR range of motion (ROM) more than 15°, and morning stiffness lasting less than?60?min were evaluated at baseline and summed to represent hip OA impairment burden. A generalized linear model with a Poisson distribution and log link function assessed the association between ACR criteria and fall risk beyond established covariates. As a secondary analysis, binary logistic regression assessed ACR criteria and the odds of falling two or more times within a year.

--Data from 210 participants were analyzed.

--Hip OA signs and symptoms were present in 97.1% of the participants, and hip OA impairment burden was significantly greater in participants who fell more than 2 times compared to single and non-fallers.

--Higher hip OA impairment burden was associated with significantly increased fall risk and odds of falling multiple times after adjustment for covariates.

Conclusively, Older adults with chronic low back pain CLBP and concomitant hip impairments are an at-risk group for falling. Healthcare professionals should employ falls screening and preventive measures to avoid negative sequelae in this vulnerable population.
