Kinematics of sagittal spine and lower limb movement in healthy older adults during sit-to-stand from two seat heights

Abstract

Study Design. A cross-sectional study to examine the sagittal kinematics of spine and lower limb movement during sit-to-stand (STS). Objective. To describe the sagittal kinematics of the spine and lower limb in healthy older adults during STS from 2 seat heights. Summary of Background Data. Older adults with age-related changes in the neuromusculoskeletal system are likely to have difficulty in STS. However, little is known about movement of the spinal regions and their interaction with the lower limb during STS, and the effect of seat height. Methods. Thirty-two healthy older adults aged over 60 years were videotaped performing STS from 2 seat heights. A 2-dimensional video motion analysis ..
