Differential Effectiveness of Psychological Interventions for Reducing Osteoarthritis Pain
A new randomized, controlled clinical trial from France investigated the effectiveness of 8-session Eriksonian hypnosis and 8-session Jacobsonian progressive relaxation for the reduction of osteoarthritis pain, using subjects with knee or hip pain. Patients were randomly assigned to one of the intervention groups or a control group. Overall, results demonstrated that the two experimental groups had a lower level of subjective pain than the control group, and that the level of subjective pain decreased with time. In addition, pain reduction occurred more rapidly for the hypnosis group. Results also showed that both hypnosis and relaxation are effective in reducing the amount of analgesic medication taken by participants.
