Frozen shoulder: MET vs Kaltenborn – Which Works Best?
Key insights: 60-second read
- 2023 study compared MET vs Kaltenborn for chronic frozen shoulder – both improved range of motion equally.
- MET (Muscle Energy Technique) was superior for pain and function – active patient involvement led to greater pain reduction and better daily task performance.
- Kaltenborn mobilisation is passive, MET is active – MET uses gentle isometric contractions to recruit the patient's own muscles.
- Why MET may win: neurological inhibition of pain, improved proprioception, and patient control over force.
- Part of a comprehensive plan – both techniques were used alongside heat and pendulum exercises; MET is a valuable component, not a standalone miracle.
If you're struggling with the stiffness, pain, and impracticality of a frozen shoulder (adhesive capsulitis), you'll know that finding relief is the priority. A 2023 clinical study put two uncommon physio techniques - Muscle Energy Technique (MET) and Kaltenborn mobilisation - head-to-head. Let's break down the specific results and what they may mean for your recovery.

The Study at a Glance
Objective: To directly compare the effectiveness of the Muscle Energy Technique (MET) and the Kaltenborn Mobilisation Technique (KMT) on range of motion, pain, and function in chronic frozen shoulder.
Participants: 32 adults with chronic "frozen stage" adhesive capsulitis (stiffness >3 months, significant loss of motion). Both groups received the same baseline care: moist heat, stretching, and pendulum exercises.
Intervention: One group received passive joint glides (KMT), the other received active, resisted contractions (MET), for 10 treatment sessions over two weeks.
How The Techniques Were Specifically Performed
Understanding the difference in application is key to understanding the results.
Kaltenborn Mobilisation (KMT)
The Approach: Passive, therapist-driven. The therapist applies graded glides and traction to the shoulder joint to stretch the capsule.
- Glenohumeral Traction: Gentle pulling to separate joint surfaces.
- Ventral & Caudal Glides: Specific gliding motions to restore accessory joint movement, held for 30 seconds each.
The patient remains relaxed while the therapist moves the joint.
Muscle Energy Technique (MET)
The Approach: Active, patient-involved. The therapist positions the shoulder at its restriction barrier. The patient then performs a gentle, submaximal contraction away from the barrier.
- For a stiff shoulder: A 10-second isometric contraction of the internal rotators to improve external rotation.
- After relaxing, the therapist gently moves the joint to a new, improved barrier. Repeated for 5 repetitions.
The patient is an active participant in unlocking their own stiffness.
The Head-to-Head Results: What Improved More?
Both groups improved, but the between-group comparison tells the crucial story.
| Outcome Measure | Kaltenborn (KMT) Result | Muscle Energy (MET) Result | Clinical Takeaway |
|---|---|---|---|
| Range of Motion (External Rotation & Abduction) | Significantly Improved | Significantly Improved | Statistically Equal. Both techniques were equally effective at restoring lost shoulder mobility. |
| Pain (Numeric Pain Rating Scale) | Significantly Reduced | Significantly Reduced More | MET was superior. The active MET approach led to greater pain reduction than passive mobilisation. |
| Function (SPADI Questionnaire) | Significantly Improved | Significantly Improved More | MET was superior. Greater pain relief and active involvement likely translated to better functional gains in daily tasks. |
A Physio's Analysis: Why Might MET Have an Edge?
This study aligns with a key principle in modern rehab: active strategies often outperform purely passive ones for lasting change. MET's superiority in pain and function could be due to:
- Neurological Inhibition: The gentle isometric contraction may help calm overactive pain signals and relax guarding muscles more effectively.
- Patient Agency & Proprioception: Being actively involved helps retrain the brain's sense of the joint, improving movement confidence.
- Safety & Comfort: MET allows the patient to control the contraction force, which may feel safer and less provocative than a therapist-applied stretch on a very stiff, painful joint.
Study Limitations & Who This Applies To
It's important to interpret these findings within the study's context:
- Specific Population: Results apply to chronic "frozen stage" adhesive capsulitis. Different stages (like the very painful "freezing" stage) may benefit more/less from alternative approaches.
- Short-Term Focus: The study only measured outcomes immediately after 2 weeks of treatment. Long-term durability of results needs more research.
- Part of a Package: Both techniques were applied alongside heat and exercises. The findings support MET as a valuable component of a comprehensive treatment plan, not a standalone miracle.
Integrating This Into Your Rehab
As a physio, this research reinforces a patient-centred approach. For a chronic stiff shoulder:
- Don't Just Stretch It, Engage It: Incorporate active techniques like MET to reduce pain and build confidence alongside mobility work.
- Match the Tool to the Phase: In the very painful phase, gentle MET and pain-modifying strategies may take priority. In the stiff phase, a combination of MET and careful mobilization can be powerful.
- Function is the Ultimate Goal: The superior functional improvement with MET is a critical finding. Rehab must always connect to making daily life and meaningful activities easier.

Frequently Asked Questions
Can I do MET on myself at home?
Some gentle self-MET variations exist, but it's best learned from a physio. The precise positioning and barrier engagement are important for safety and effectiveness. A therapist can teach you a home program tailored to your stage of frozen shoulder.
Which technique is less painful for frozen shoulder?
The study found MET led to greater pain reduction, and its patient-controlled force often feels safer than a passive stretch. However, individual responses vary. A skilled physio will adjust both techniques to your comfort level.
How many sessions are typically needed?
In this study, significant improvements were seen after 10 sessions over 2 weeks. Chronic frozen shoulder often requires a longer course of care, but consistent therapy combined with home exercises can yield meaningful gains.
One profound insight from this post
"Active strategies often outperform purely passive ones for lasting change. MET allows the patient to control the force, which may feel safer and more effective."
Living With Persistent Pain?
If your pain has lasted longer than expected, feels disproportionate to activity, or hasn't responded to standard treatment, you may benefit from a broader approach. Learn more about our shoulder pain physiotherapy services in Port Macquarie.
