About

The main aim of this study is to identify factors that may be associated with a better or worse response to interventional pain management therapies for the treatment of chronic lumbar pain in adult patients. If several predictive factors are to be identified, a predictive model will be developed.

Full description

Chronic lumbar pain is a common affection in the adult population, and an important source of chronic incapacity and impaired quality of life. There is a wide range of therapeutic options for the treatment of chronic lumbar pain. This study will analyze the response to several interventional pain management techniques and will search for factors that may be associated to a better or worse response to the techniques.

Enrollment: 400 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients older than 18 years old with chronic lumbar pain to whom one of the following interventional pain management techniques has been indicated:
• Radiofrequency lumbar facet joint injection
• Radiofrequency lumbar facet joint denervation
• Lumbar epidural corticosteroid injection
• Caudal epidural corticosteroid injection
• Pulsed radiofrequency of the lumbar dorsal root ganglion
• Dorsal root ganglion injection

Exclusion criteria

• Patients that have not undergone the interventional pain management technique. The interventional pain management technique is considered not performed if it is not done after a twelve month period after recruitment.
• Patients who are not willing to participate.
• Patients of whom it is impossible to obtain data of response.
• Patients who undergo low back surgery while they are in the study.
• Patients who suffer from an intercurrent disease that may interfere with the evaluation of chronic lumbar pain.
• Patients who suffer from myofascial pain syndromes.
• Patients who undergo pulsed radiofrequency denervation for the treatment of sacroiliac joint syndrome.
