Equitation Science: Effects of Lumbar Curve on Shoulder Hip Heel Alignment. Tsang et al 2024. 

When riders are directed to adopt shoulder-hip-heel postural alignment, it is critical for postural health to evaluate the rider's lumbar spinal alignment. Analysis by Caroline Lindsay. In this presentation I analyse a scientific paper on an equitation topic as part of my doctoral studies focusing on rider posture, pain and performance. This recent paper investigates postural control across three conditions of erect (neutral), hyperlordosis and swayback lumbar conformation in healthy adults who simulated those spinal alignments. The researchers created predictable and unpredictable conditions for each of the three postures to determine the effects across the three spinal alignments. I add my own comments to this study throughout. The researchers are SMH Tsang, EHW Chan, JYH Chan, GPY Huang, KKT Lam, EWY Lam, ACL Fu and ER Sun. The title of the paper is Reactive postural adjustment in response to predictable and unpredictable perturbations in healthy adults: A comparison between swayback, hyperlordotic and erect postures.
