1 1 Principles of Exercise Therapy Lower Back Pain 1. Facet joint pain 2. Spondylolysis & Spondylisthesis 1. Exercise Therapy turns the patient into an active participant and not just a passive recipient of therapy, making possible a natural and gradual transition from treatment to exercise. 2. The responsibility for his or her own health is transferred to the patient, forming the basis for his or her own mastery, a precondition for permanent improvement.

2 O Sullivan P.B., Twomey L.T. Method and Classification Evaluation of specific stabilizing exercise in the treatment of chronic low back pain with radiologic diagnosis of spondylolysis or spondylolisthesis Spine 24: , patients randomized in two groups Training for 10 weeks Group 1: Trained transversus abdominis and multifidus Group 2: Conventional physiotherapy including training Training in Group 1 Stabilizing exercise ; Pulling-in navel 1) Initially Training in non pain-inducing positions 2) Later Training in static positions that were previously pain-inducing 3) After that Training in functional activities Training in Group 2 - Strengthening exercise + Conventional treatment Follow-up after 30 months Conclusion Group 1 (Transversus abdominis + multifidus) significant pain reduction significant improvement of function Group 2 (Conventional treatment) No significant pain reduction No significant improvement of function Low-graded training of the stabilizing musculature of the lumbar spine reduces pain and improves function O Sullivan 1997, Hides

5 Pathomechanics Spondylolisthesis Complication of spondylosis Highest incidence with L5 slipping on S1 Goal of treatment Pain relief Arrest of slip progression Minimizing deformity Type 1 Type I is called dysplastic spondylolisthesis and is secondary to a congenital defect of either the superior sacral or inferior L5 facets or both with gradual slipping of the L5 vertebra Type II A Type II A is sometimes called Lytic or stress spondylolisthesis and is most likely caused by recurrent micro-fractures caused by hyperextension. It is also called a "stress fracture" of the pars interarticularii and is much more common in males. Type II B Type II B probably also occurs from microfractures in the pars. However, in contrast to Type II A, the pars interarticularii remain intact but stretched out as the fractures fill in with new bone. Type II C Type II C is very rare in occurrence and is caused by an acute fracture of the pars. Nuclear imaging may be needed to establish diagnosis 5

$Type IV Type IV, traumatic spondylolisthesis, is associated with acute fracture of a posterior element (pedicle, lamina or facets) other than the pars interarticularis.$

6 Type III Type III, is a degenerative spondylolisthesis, and occurs as a result of the degeneration of the lumbar facet joints. The alteration in these joints can allow forward or backward vertebral displacement. This type of spondylolisthesis is most often seen in older patients. In Type III, degenerative spondylolisthesis there is no pars defect and the vertebral slippage is never greater than 30%. Type IV Type IV, traumatic spondylolisthesis, is associated with acute fracture of a posterior element (pedicle, lamina or facets) other than the pars interarticularis. Type V Type V, pathologic spondylolisthesis, occurs because of a structural weakness of the bone secondary to a disease process such as a tumor or other bone diseases.
