Analysis of compressive load on intervertebral joint in standing and sitting postures

BACKGROUND: There have been some disagreements on the comparison of disc pressures in the standing and sitting postures in literature. Most research on in vivo pressure needle measurement found higher disc pressure in sitting than in standing. The disc pressure data can help to advocate better postures for clinical advice. OBJECTIVE: The aim of this paper is to develop a procedure to study the compressive load on intervertebral joint in the standing and sitting postures through the approach of motion capture and musculoskeletal modeling. METHODS: The marker data of six subjects performing various standing and sitting postures was obtained during the motion capture experiment and used to train the musculoskeletal model with an enhanced discretized spine developed for subject in the inverse and forward simulations. RESULTS: Compressive loads on L3-L4 and L4-L5 joints are found higher in upright sitting than in upright standing. Slumped sitting, cross-legged sitting and flexion sitting can introduce higher compressive loads on intervertebral joints compared with upright sitting. CONCLUSIONS: These findings indicate the effects of standing and sitting postures on the spinal joint loads. The results can provide doctors and therapists with more information on clinical advice on better postures for people with spinal problems.

Joint action: essays in honour of John Shotter

Joint Action: Essays in honour of John Shotter brings together a cross-disciplinary group of fifteen respected international scholars to explain the relevance of John Shotter’s work to emerging concerns in twenty-first century social science.Shotter’s work extends over forty years and continues to challenge conventional scientific thinking across a range of topics. The disciplines and practices that Shotter’s work has informed are well established throughout the English-speaking world. This is the first publication to examine the importance of his influence in contemporary social sciences and it includes authoritative discussions on topics such as social constructionism, democratic practice, organisational change, the affective turn and human relations. The geographical diversity and disciplinary breadth of scholarly contributions imbues the book with international scope and reach.Joint Action presents a contemporary reflection on Shotter’s work that demonstrates its influence across a range of substantive topics and practical endeavours and within disciplines including management studies and philosophy as well as psychology. As such, it will appeal to researchers and postgraduate students of social sciences and related disciplines, as well as to those who have heard of Shotter’s work and want to know more about its utility and value in relation to their own research or practice.
