N2 - The 2D PEAK Motus motion analysis system was used to measure the sagittal lumbofemoral rhythm during active hip (knee) flexion in standing in 34 healthy older adults whose movement may be influenced by age-related changes in the neuromusculoskeletal system. When the thigh was raised, the lumbar spine moved concurrently with the hip joint throughout the movement. Approximately 5° of initial hip flexion occurred before 1° of lumbar flexion. Overall, the lumbar spine contributed 26.6% (29.3°) of the total thigh movement (pelvis + hip joint) during the upward (110.2°) movement phase. Compared to children and young adults, older adults demonstrated some age-related differences in sagittal lumbofemoral rhythm, including decreased hip flexion and a large variation in the hip-to-lumbar movement ratio. Clinicians and exercise instructors need to be aware of the concurrent movement interaction between the hip joint and lumbar spine when measuring hip flexion range or when instructing abdominal, hip, or lumbar exercises. The potential influence of limited range of motion of either hip or lumbar component on the movement should also be addressed.
