Date: Tues 26th Feb 2008Venue: Imperial College, South Kensington, LondonTime: 6.30pm - 9.30pm (3 hours)Cost: £28Details: See www.physiouk.co.uk for full details. This evening lecture will explore the most current evidence on the role of psoas major in stabilising the lumbar spine and sacro iliac joint. Commonly held clinical beliefs will be challenged and a case argued that:-• Psoas is not an effective hip flexor• There is almost no evidence for psoas being short• It does not produce anterior tilt of the pelvis (instead it produces posterior tilt)• It does not produce significant movement in the spine• It has a significant stability role for the lumbar spine, sacro iliac joint and the hip• It is inhibited in the presence of pain• It is easily retrainedThe presentation details a process for reviewing muscle function and dysfunction based on analysis of:1. Muscle structure and anatomy2. Biomechanical potential3. Neurophysiology of muscle recruitment4. Evidence of consistent changes related to pathological statesMuscle functional roles are defined in terms of local or global motor recruitment and in terms of potential for stabiliser or mobiliser function. Psoas major is a multi tasking muscle and the evidence to support the 'real' functional role at the lumbar spine, the sacro iliac joint and the hip joint are detailed. Strategies for retraining psoas function are also presented.
