PREPARE: presurgery physiotherapy for patients with degenerative lumbar spine disorder: a randomized controlled trial.

BACKGROUND CONTEXT

Surgery because of disc herniation or spinal stenosis results mostly in large improvement in the short-term, but mild to moderate improvements for pain and disability at long-term follow-up. Prehabilitation has been defined as augmenting functional capacity before surgery, which may have beneficial effect on outcome after surgery.

PURPOSE

The aim was to study if presurgery physiotherapy improves function, pain, and health in patients with degenerative lumbar spine disorder scheduled for surgery.

STUDY DESIGN

A single-blinded, two-arm, randomized controlled trial (RCT).

PATIENT SAMPLE

A total of 197 patients were consecutively included at a spine clinic. The inclusion criteria were patients scheduled for surgery because of disc herniation, spinal stenosis, spondylolisthesis, or degenerative disc disease (DDD), 25-80 years of age.

OUTCOME MEASURES

Primary outcome was Oswestry Disability Index (ODI). Secondary outcomes were pain intensity, anxiety, depression, self-efficacy, fear avoidance, physical activity, and treatment effect.

METHODS

Patients were randomized to either presurgery physiotherapy or standardized information, with follow-up after the presurgery intervention as well as 3 and 12 months post surgery. The study was funded by regional research funds for US$77,342. No conflict of interest is declared.

RESULTS

The presurgery physiotherapy group had better ODI, visual analog scale (VAS) back pain, EuroQol-5D (EQ-5D), EQ-VAS, Fear Avoidance Belief Questionnaire-Physical Activity (FABQ-PA), Self-Efficacy Scale (SES), and Hospital Anxiety and Depression Scale (HADS) depression scores and activity level compared with the waiting-list group after the presurgery intervention. The improvements were small, but larger than the study-specific minimal clinical important change (MCIC) in VAS back and leg pain, EQ-5D, and FABQ-PA, and almost in line with MCIC in ODI and Physical Component Summary (PCS) in the physiotherapy group. Post surgery, the only difference between the groups was higher activity level in the physiotherapy group compared with the waiting-list group.

CONCLUSIONS

Presurgery physiotherapy decreases pain, risk of avoidance behavior, and worsening of psychological well-being, and improves quality of life and physical activity levels before surgery compared with waiting-list controls. These results were maintained only for activity levelspost surgery. Still, presurgery selection, content, dosage of exercises, and importance of being active in a presurgery physiotherapy intervention is of interest to study further to improve long-term outcome.
