Progressive Muscle Relaxation: What Clinical Resources Describe
Progressive muscle relaxation (PMR) is a structured relaxation technique developed in the 1930s by American physician Edmund Jacobson. This summary pulls from clinical resources and published research to describe what the technique involves, what it is used for, and what the evidence supports.
This article does not claim personal experience with PMR. The information below reflects what published clinical resources and research describe.
The Technique
Progressive muscle relaxation involves systematically tensing and then relaxing different muscle groups throughout the body. The original Jacobson protocol involved 30+ muscle groups and tensing for extended periods. Modern abbreviated versions typically use 7 to 16 muscle groups and shorter tension periods.
The basic procedure for a common abbreviated version:
- Find a quiet, comfortable position (typically seated or lying down).
- Begin with the feet: tense the muscles for 5 to 10 seconds, then release and notice the relaxation for 20 to 30 seconds.
- Move progressively through muscle groups: calves, thighs, abdomen, hands, arms, shoulders, face.
- End with several minutes of focused breathing and overall body awareness.
The American Psychological Association’s stress resources describe PMR as one of several structured relaxation techniques that can be useful for managing stress responses.
What the Evidence Supports
Published research on PMR includes:
Acute anxiety reduction: Multiple studies, including those indexed in PubMed Central, find that PMR produces measurable acute reductions in self-reported anxiety and physiological markers including heart rate and blood pressure.
Use in clinical settings: PMR has been studied as a component of treatment for various conditions, including generalized anxiety disorder, insomnia, and chronic pain. Reviews note that PMR is often used alongside other interventions rather than as a standalone treatment.
Pregnancy and childbirth: Some evidence supports PMR for anxiety and pain management during pregnancy and labor. The clinical resources note that pregnant users should consult healthcare providers before starting any new relaxation practice.
Chronic conditions: PMR has been studied as a complementary intervention for conditions including hypertension, cancer-related anxiety, and chronic pain. Reviews note effects are typically modest and PMR is one component of broader treatment.
Common Variations
Several abbreviated PMR protocols have been developed:
Bernstein-Borkovec: A widely-used 16-muscle-group protocol from the 1970s, used in much of the published research. Reviews note this protocol is the basis for many therapist-led PMR training programs.
Brief PMR: Shortened versions using 4 to 7 muscle groups, often used in self-help contexts and apps.
Autogenic training combined with PMR: Some programs combine PMR with autogenic training (focused phrases suggesting warmth and heaviness). Reviews note this combination has been studied in clinical settings.
Body scan variations: Many modern apps and programs offer “body scan” variations that include elements of PMR alongside mindfulness practices.
What the Evidence Does Not Support
There are claims about PMR that outrun the evidence:
- That PMR can replace medical treatment for diagnosed anxiety disorders or other conditions. The clinical resources consistently position PMR as a complement to professional care.
- That PMR produces instant or dramatic effects. Most published research describes modest effects that accumulate with practice.
- That any specific protocol is universally best. Different versions may suit different users and contexts.
When PMR May Not Be Appropriate
Clinical resources note several situations where PMR may not be appropriate or requires modification:
- Muscle injuries or pain: Tensing injured or painful muscles may worsen the condition.
- Pregnancy: Some muscle groups (particularly abdominal tensing) require modification during pregnancy. Healthcare provider consultation is recommended.
- High blood pressure: While PMR is often used for blood pressure management, sudden tensing can briefly raise blood pressure. Modifications exist for users with hypertension.
- Severe anxiety or PTSD: For some users, intense body focus can increase rather than decrease anxiety. Modifications or alternative approaches may be needed.
- Specific physical conditions: Some neurological or musculoskeletal conditions may make tensing certain muscle groups inadvisable.
Learning the Technique
Clinical resources consistently recommend:
- Initial instruction from a qualified teacher, audio recording, or video.
- Daily practice for several weeks to develop proficiency.
- Starting with shorter sessions (5 to 10 minutes) and gradually extending.
- Using PMR in various contexts (not just during acute stress) to build the skill.
Reviews note that the most common reason for dissatisfaction is inadequate practice time — the technique generally requires several weeks of regular practice before becoming effective for stress management.
Combining PMR with Other Approaches
Clinical resources consistently note that PMR is often most effective when combined with other approaches:
- Cognitive behavioral therapy (CBT): PMR as a relaxation component within broader CBT.
- Mindfulness practices: Combining body-based relaxation with mindfulness of thoughts.
- Sleep hygiene: PMR as a component of pre-sleep routines.
- Other stress management: Breathing exercises, exercise, social connection, and other practices.
The Cleveland Clinic’s relaxation resources describe PMR as one tool among several for stress management.
