Treatment of Muscle Knots
The most effective approach to treating muscle knots (myofascial trigger points) includes thermal interventions such as heat application, stretching exercises, and physical therapy, while massage therapy may provide symptomatic relief despite limited evidence for OA-specific outcomes. 1
Understanding Muscle Knots
Muscle knots, medically known as myofascial trigger points (MTrPs), are hyperirritable spots within taut bands of skeletal muscle that are painful on compression and can cause referred pain, motor dysfunction, and autonomic phenomena 2. They are extremely prevalent, found in up to 85-95% of people with various pain conditions 3.
Treatment Algorithm
First-Line Treatments:
Thermal Interventions
Exercise Therapy
- Strengthening exercises targeting the affected muscle groups and surrounding areas 1, 4
- Stretching of the affected muscles to release the taut bands 5
- Begin with low-load exercises and gradually progress as tolerated 4
- Aquatic exercises in warm water (86°F) can provide additional pain relief through buoyancy and warmth 1
Pain Management
Second-Line Treatments:
Manual Therapy Techniques
- Despite conditional recommendations against massage therapy for OA specifically, the Patient Panel acknowledged massage may have benefits for symptom management 1
- Techniques such as "spray and stretch" may provide relief for myofascial trigger points 2, 5
- Instrument-assisted soft tissue mobilization has shown to increase pain threshold of trigger points 6
Advanced Interventions (for persistent cases)
Treatment Progression
Follow a phased approach to rehabilitation 4:
- Initial Phase (0-4 weeks): Focus on pain control and protected range of motion
- Intermediate Phase (4-8 weeks): Progressive strengthening exercises
- Advanced Phase (8-12 weeks): Activity-specific training
Important Considerations
- Avoid high-impact activities that may increase joint loading and exacerbate symptoms 1
- Identify and address perpetuating factors such as poor posture, body mechanics, psychological stress, and sleep issues 5
- Return to full activity should only occur when there is complete resolution of pain, full range of motion, and strength symmetry >90% compared to unaffected side 4
Cautions and Pitfalls
- TENS therapy is strongly recommended against for knee and hip OA due to lack of demonstrated benefit 1
- Pulsed vibration therapy is conditionally recommended against due to insufficient data 1
- Iontophoresis lacks published RCTs evaluating its effectiveness for OA 1
- While manual therapy techniques may benefit certain conditions like chronic low back pain, limited data in OA show little additional benefit over exercise alone 1
Remember that early intervention with appropriate thermal treatments, exercise therapy, and pain management can help prevent chronic issues and improve outcomes for muscle knots.
