Somatic therapy for chronic pain, in all its current forms, works through the body. Sensorimotor Psychotherapy tracks physical sensation as a gateway to processing trauma. Somatic Experiencing uses pendulation and titration to discharge stored nervous system activation. Embody Lab-style training teaches practitioners to read and work with the client’s physical experience as the primary therapeutic material.
PRT (Pain Resolution Therapy) does none of this.
The distinction matters, because a practitioner who has trained in somatic work and is now considering PRT needs to understand what they’re adding. PRT is a different tool for a different mechanism. Choosing between them depends on what you believe is maintaining your client’s pain.
Somatic approaches operate on a body-based model. The premise: trauma and psychological distress get stored in the body as physical tension, restricted movement, autonomic dysregulation. The intervention works through the body to release what the body is holding. The practitioner guides the client’s attention to physical sensation, supports the body in completing interrupted defensive responses and supports nervous system regulation through breath, movement and awareness.
This model fits a specific presentation. When a client’s pain correlates with visible physical holding patterns, when the pain is accompanied by autonomic dysregulation (startle responses, breath restriction, temperature changes), somatic work has a clear target and a mechanism that makes clinical sense.
PRT operates on a psychological-structural model. The premise: pain persists because it serves a function within the client’s relational system. The pain organizes relationships, prevents confrontations, maintains roles or provides a solution to an interpersonal problem the client can’t solve directly. The intervention is directive: the practitioner identifies the function, designs a specific intervention to disrupt the maintaining structure and assigns behavioral tasks that alter the pattern.
PRT doesn’t ask the client to track physical sensations. There are no body scans, no pendulation, no attention to breath as a therapeutic vehicle. The practitioner reads the psychological and relational structure of the pain and intervenes there.
The practical question for the clinician is which mechanism applies to the client in the room.
Some chronic pain presentations carry a clear somatic signature. The client tenses visibly when discussing certain topics. Their pain maps onto a recognizable pattern of physical bracing. Autonomic markers are present. For these clients, somatic work addresses the mechanism directly.
Other chronic pain presentations have no somatic signature. The client’s body is relaxed in session. The pain has no consistent relationship to physical states or postures. What the pain does have is a consistent relationship to relational situations: it escalates during visits from specific family members, disappears when the client is alone, worsens when a boundary needs to be set. The pain tracks interpersonal dynamics.
For that second population, somatic therapy targets a mechanism that isn’t driving the symptom. The client can track sensations, regulate their breathing and complete pendulation exercises without effect, because the maintaining structure is relational.
PRT was designed for those cases. The intervention reads the relational function of the pain and addresses that function through directive, structured treatment. The pain resolves because its structural basis changes.
Both tools have a clinical purpose. A practitioner who understands both can assess which mechanism is operating in a specific case and choose accordingly. The error, common in the current training landscape, is assuming that all chronic pain with a psychological component requires a body-based intervention. Some chronic pain is maintained somatically. Some is maintained by the psychology and the relational system around the person in pain. Knowing the difference changes what you do and whether it works.
