PainSci summary of Lederman 2011: ?This page is one of thousands in the bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible.

This article is a bloody brilliant deconstruction of the underlying assumptions of the vast majority of pseudo-quackery in the manual therapies. It’s technical and academic, not for the lay reader, but absolutely required reading for professionals. Be sure to read his other excellent essay, “The Myth of Core Stability”.

Manual and physical therapists often use a postural–structural–biomechanical (PSB) model to ascertain the causes of various musculoskeletal conditions. It is believed that postural deviations, body asymmetries and pathomechanics are the predisposing/maintaining factors for many musculoskeletal conditions. The PSB model also plays an important role in clinical assessment and management, including the choice of manual techniques and the exercise prescribed. However, this model has been eroded by research in the last two decades introducing profound challenges to the practice of manual and physical therapy. This article will examine how the sciences are challenging the PSB model, using lower back pain (LBP) as an example.

This page is part of the PainScience BIBLIOGRAPHY, which contains plain language summaries of thousands of scientific papers & others sources. It’s like a highly specialized blog. A few highlights:
