Background It is assumed that the lumbar movement pattern observed during a clinical test is representative of the movement pattern used during a functional activity. Very little is known about how the lumbar movement pattern during a clinical test is associated with the lumbar movement pattern during a functional activity and how the lumbar movement pattern is associated with functional limitation. Objective The purpose was to examine the lumbar movement pattern during a clinical test and a functional activity test in people with and people without low back pain (LBP), and the relationship of lumbar motion to LBP‐related functional limitation. Design Observational study. Participants 16 back‐healthy adults and 32 people with chronic LBP. Methods Participants performed a standardized clinical test of forward bending and a functional activity test of picking up an object. Main Outcome Measurements Maximal lumbar excursion and lumbar excursion at 0% to 50% and 50% to 100% of movement time were examined. Results Significant associations were present between the two movement tests for both back‐healthy people and people with LBP (r = 0.47‐0.73). In people with LBP the amount of lumbar motion in the 0% to 50% of movement time interval for both tests was significantly associated with functional limitation (r = 0.43‐0.62). Conclusion Lumbar movement patterns were similar between the two tests, and lumbar motion early in the movement of a functional test was related to self‐report of functional limitation.
