PurposePhysical rehabilitation is one of the major forms of treatment of chronic low back pain. The ability of some patients to cooperate is limited by pain. Since 1992 continuous epidural analgesia has been combined with a physical rehabilitation programme for patients with chronic low back pain who have been unable to make progress with conventional physical rehabilitation due to severity of pain.MethodThis study reports a series of 46 consecutive patients with chronic back pain admitted over a 6 month period to a 5-day inpatient rehabilitation programme. A lumbar epidural catheter was inserted and bupivacaine 0.125% was infused at a rate that produced analgesia without sensory or motor deficit over a period of 5 days. An intensive mobilizing physiotherapy programme was instituted. Physical and psychological parameters were measured on day 1, after 1 week, after 1 month and after 1 year.ResultsTime to complete a 50 m walk, time from sitting to standing, and spinal flexion were improved at 1 week and 1 month, but only time to complete the walk remained improved at 1 year. In Goldberg's General Health Questionnaire 28 scores were improved for social dysfunction, somatic symptoms, anxiety and insomnia, and depression, at 1 week and 1 month but only social dysfunction remained improved at 1 year. Using a Visual Analogue Scale pain ratings were unaltered after 1 year.ConclusionContinuous 5 day epidural analgesia combined with intensive physiotherapy may offer a means of initial rehabilitation of chronic low back pain. The initial benefit was most marked at 1 week, with benefit still evident after 1 month. However, the benefit decreased with time. This technique may be of value as part of a more comprehensive programme of physical and psychological rehabilitation.
