Abstract
Lumbar discectomy is now the operation of choice for lumbosacral radicular syndrome. Few studies of high quality have been performed on the post surgical management of these cases. The studies that have been reported compared one exercise regime to another. This study compares an exercise group with a true control group involving no exercise or formal rehabilitation. This is a randomized controlled trial comparing post surgical lumbar discectomy management regimes.
Ninety three lumbar discectomy patients were randomized to two groups. Group A; the control group followed usual surgical advice which was to resume normal activity as soon as pain allowed. Group B; undertook a six month supervised non aggravating gym rehab programme. Both groups were followed for a one year period using validated outcome measures and a questionnaire. The results are based on an intention-to-treat analysis.
Patients in both groups improved during the one year follow up period (P=0.001). However there was no statistical difference between groups at the clinical end point (Roland Morris P=0.83, Oswestry Low back index P=0.90). Group B patients returned to work seven days earlier than group A patients and had fewer days off work in the one year follow up period but this difference was not statistically significant.
There was no statistical advantage gained by the patients who performed the gym rehabilitation programme after one year follow up. These are the preliminary one year results of a three year follow up study.
