Trunk muscle activation and coactivation changes in patients with multiple myeloma undergoing vertebral consolidation surgery: a study performed by using movement analysis technologies

Multiple myeloma (MM) is a neoplasm characterized by the proliferation of plasma cells, which expand at the level of the bone marrow causing the typical multiple osteolytic lesions.Patients with multiple spinal injuries often complain of pain and stiffness that limit motility and activities of daily and work life.The current scientific scenario supports the positive effects of vertebroplasty on patients' lives. As a matter of fact, the literature shows that such procedure gives patients important and lasting pain relief.This study aims to test the above hypothesis and to objectify how spinal motility and stability vary after vertebroplasty surgery.
