Another in our ‘getting your thesis out there‘ series. This one from Adriaan Louw, PT, PhD. Congrats Adriaan on finishing your thesis!
Background: On average one in three patients following lumbar surgery (LS) for radiculopathy experience persistent pain and disability following surgery. No perioperative treatments have shown any ability to decrease this persistent pain and disability. In another challenging low back pain (LBP) population, chronic LBP, pain education focusing on the neurobiology and neurophysiology of pain, has shown an ability to reduce reported pain and disability. The purpose of this research study was to develop and test a preoperative neuroscience education program for LS and determine its effect on pain and disability following LS.
Research Design and Methods: After a series of studies, a newly designed preoperative neuroscience educational tool (PNET) was developed. Eligible patients scheduled for LS for radiculopathy participated in a multi-center study where they were randomized to either receive usual care (preoperative education), or a combination of usual care plus one session covering the content of the PNET, as delivered by a physical therapist in a one-on-one verbal session. Prior to LS, and one, three and six months after LS, 67 patients completed a series of self-report outcome measures consisting of LBP and leg pain rating (Numeric Rating Scale), function (Oswestry Disability Index), fear avoidance (Fear Avoidance Beliefs Questionnaire), pain catastrophization (Pain Catastrophization Scale), pain knowledge (Pain Neurophysiology Questionnaire), various beliefs and experiences related to LS (Likert Scale), and post-operative utilization of healthcare (Utilization of Healthcare Questionnaire).
Results: At one year follow up there were no statistical difference (p <0.05) between the experimental and control groups in regards to the primary outcome measures of function (p = 0.296), LBP (p = 0.077) and leg pain (p = 0.074). The experimental group scored significantly better on various questions regarding beliefs and experiences having undergone LS, compared to the control group indicating a more positive surgical experience. Analysis of healthcare utilization showed that patients who received the preoperative neuroscience educational program had dramatically less health care utilization (medical tests and treatments) in the one-year following LS (p = 0.001), resulting in a 42% savings in healthcare cost.
Conclusion: The addition of a preoperative neuroscience educational program to usual care for LS for radiculopathy resulted in a profound behavioral change leading to a more positive surgical experience, decreased healthcare utilization and resultant savings, despite persistent pain and disability.
