A randomized study of manual therapy with steroid injections in low-back pain. Telephone interview follow-up of pain, disability, recovery and drug consumption.

A total of 101 outpatients with acute or sub-acute low-back pain was randomly allocated to one of two treatment groups. One group was given standardised conventional and optimised activating treatment by primary health care teams. The other group received, according to a pragmatic approach, another treatment programme including manipulation, specific mobilisation, muscle stretching, autotraction and cortisone injections. The treatment effect was evaluated by standardised telephone interviews 3, 7, 14, 21 and 90 days after the start of treatment. The two groups were similar in most of the pretrial variables, including age, sex, occupation, education, previous low-back pain problems, previous treatment, sick-leave, findings at the physical examination, quality-of-life score, presence of common symptoms, disability rating and pain score. In the early phase as well as at the 90 days' follow-up, the group receiving manual therapy had significantly less pain, less disability, faster rate of recovery and lower drug consumption, indicating that this type of treatment is superior to conventional treatment.
