Acute non-specific low back is an enigma that has plagued society for centuries and little progress has been made to manage its prevalence and reported incidence. There are many concepts aimed at treating the condition but they have not been able to answer the important questions of what is, how and why is low back pain such a problem, going forwards. Core stability exercises is a relatively recent concept for the management of low back pain with the assumption that it may be the answer to not only the treatment but also a route by which an explanation for its onset can be based. There is an increasing scepticism that this is indeed the case. The work within this book explores how this concept may indeed be valuable but also offers a new way to consider what actually happens during an episode of acute low back pain and why historical methods of evaluation may not suffice in providing supporting measurable outcome measures because of the increasing evidence that suggests that the evaluation of low back pain should be about spinal kinematics and not range of movement or areas of spinal tenderness alone.
