Both biofeedback training (EMG) and group treatment using operant techniques are effective in reducing chronic pain. The aim of this research study is the analysis of the variables which can predict the success of these treatments at the end and after the 6-month follow-up period. The research study involved 50 patients aged between 18 and 65 who suffered from chronic pain for at least six months (23 patients with pain in the lumbar region and 27 patients with pain in the cervical and dorsal regions). The patients were assigned randomly to one of the two foreseen treatment conditions: 12 sessions of about 60 minutes of EMG biofeedback, with the electrodes placed in the region of pain and 12 sessions of about 80 minutes in a small group. Both treatments had a duration of 9 weeks; both treatments included instructions for exercises at home. 23 out of the initial 25 patients completed the EMG biofeedback treatment, whereas only 15 out of the initial 25 patients completed the operant treatment. At the end of both treatments a reduction in the quantity of analgesics assumed, the subjective pain intensity, the self-evaluations quoted during the «diaries of pain» was observed. These improvements continued at the 1-month and at the 6-month follow-ups. However, no changes in the psychophysiological variables (stress profile) were recorded. Successful prognostic variables in the biofeedback training scored low on the «solicitous responses» scale and scored high on the «life control» scale of the Multidimensional Pain Inventory (MPI). The high drop-out rate (15 out of 25) compromises the analysis of the successful prognostic variables as far as the operant treatment group is concerned.
