Background: Lumbar vertebrae carry the greatest load from the spinal column, often leading to several pathologies, including degenerative disc disease (DDD), potentially disturbing spinal movement patterns. Mobilisation increases hypomobile segment mobility, however there is little evidence on mobilisation in patients suffering from different types of DDD.
Objective: To assess the efficacy of mobilisation in young patients with DDD, as diagnosed by MRI.
Methods: Thirty patients (24-35 years) participated in this study, and were divided into two groups, based on progression levels of DDD diagnosed by MRI (protrusion-PRO/extrusion-EXT). Twenty sessions of sustained stretch mobilisation (grade III) were applied to both groups over four weeks. Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), straight leg raise (SLR), passive lumbar extension (PLE) and lumbar range of motion (ROM) assessed outcome variables. Three trial stages were investigated: pre-therapy (1), post-therapy (2) and follow-up (3).
Results: Age (p= 0.007) and NRS (p= 0.002) were significantly different before therapy. Patient outcomes were significantly improved for all parameters in both groups, except SLR which improved in the EXT group only (p= 0.043).
Conclusions: Applied treatments improved patient outcomes and were statistically significant in both groups, however, better outcomes were observed in the EXT group during follow-up. Mobilisation was a safe and effective procedure for the treatment of DDD.
