Abstract:
The primary goal of this project was to investigate a novel model for motion capture that differentiated thoracic and lumbar kinematics during running in an effort to identify age-related differences in thoracolumbar, pelvic, and lower extremity running kinematics, running speed, and physical measures. This cross-sectional, comparative analysis included 100 healthy participants between the ages of 18-39 (n=50) and 50-75 (n=50). All participants underwent three-dimensional video analysis while running on a treadmill at self-selected (SSS) and controlled (CRS) running speeds. The results of the study revealed that the novel thoracolumbar marker set was a reliable technique for measuring thoracic and lumbar spine range of motion in runners across the age spectrum. Older healthy adults (OHA) moved through less angular excursion at SSS in all planes of motion with significant findings observed in 12 of the 14 angles reported. At controlled running speed (CRS), despite moving through less angular excursion than younger healthy adults (YHA), the differences between OHA and YHA angular excursions were less pronounced. Significant age-related differences were identified in initial T1 postural angles, T12 extension active range of motion (AROM), and thoracic 14 AROM. However, these differences in physical measures across the age spectrum did not correlate to angular excursion at SSS in OHA. The results of this study revealed that SSS does influence angular excursion. However, angular excursion in OHA is not correlated to age related changes in spine posture and spine AROM. Comprehensive biomechanical analysis of the entire kinematic chain is necessary to determine the impact musculoskeletal imbalance has on running form. The results of this study have established a framework for future studies to build upon. Specifically, if biomechanical parameters related to aberrant spine and LE kinematics can be identified, the potential exists to reduce the risk of injuries in runners via targeted interventions developed based on these findings that improve spine and LE kinematics during running.
