This article examines the treatment of chronic pain. Standard physiotherapy treatments have shown only modest efficacy. We describe here psychological therapies, of proven effectiveness, which may be associated with the physiotherapy treatment. Acceptance and Commitment Therapy is discussed in particular. Following this, we present a study in which psychological techniques were delivered by physiotherapists. The article proposes possible consequences linked to this approach and suggests further studies on the topic, which could have significant repercussions in the clinical field.
