What is the difference between the thigh to trunk angle, thigh to pelvis angle, and sagittal pelvic angle? How do they relate to hip flexion and posterior pelvic tilt? In this webinar, I’ll first review the difference between joint range of motion and body segment angles so that you can relate mat exam findings to seated posture and wheelchair seating angles. Then we will delve deeper into the distinctions between the relative body segment angles of the trunk, pelvis and thigh, and how these angles relate to typical postures of the spine and pelvis such as kyphosis, lordosis, and posterior or anterior pelvic tilt. Being able to visualize and measure these angles can help you to better understand and describe complex postural deviations, which will improve your ability to provide appropriate seating interventions. Case studies will be used to show the clinical application of these concepts.
Participants will be able to translate a hip flexion angle measure from a mat exam into a thigh to trunk angle measure and corresponding seating angle.
Participants will be able to define and explain the differences between the thigh to trunk angle, thigh to pelvis angle, and sagittal pelvic angle.
When provided with two hypothetical measures of thigh to trunk angle and thigh to pelvis angle, participants will be able to distinguish if the seated person’s posture is kyphotic or lordotic.
