THORACIC SPINE KINEMATICS AND KINETICS (BIOMECHANIS OF SPINE)Physiotherapy Tutorial Instagram: https://www.instagram.com/_movementscience_/ linked in : https://www.linkedin.com/in/adhip-nadkarni-5b45241a6/ twitter : https://twitter.com/adhip_nadkarni summary of the video with the time for reference: 1.Kinematics -Upper thoracic region 0:54 -Flexion is limited due to posterior longitudinal ligament and ligamentum flavum -Extension is limited by spinous process, lamina and capsule -Lateral flexion and rotation is coupled which occur in same direction -lateral flexion and rotation is limited by rib cage -Lower thoracic region 3:28 -facet in saggital plane which increases flexion extension and reduces rotation -Lateral flexion and rotation is coupled which occur in opposite direction -Ribs 5:06 -ribs covexity increases when thoracic vertebra rotates hence the adaptability of ribs influences the mobility at thoracic spine and also mobility at costo vertebral and costotransverse joint 3.Kinetics 7:00 -high compressive forces -Line of Gravity passes anteriorly -This produces flexion moment -Countered by extensors and posterior longitudinal ligament #biomechanicsofspine #spinebiomechanics #vertebralcolumnbiomechanics
