Triggered by Trigger Points? Maybe It's Nerves Playing Tricks on You!

The concept of muscle trigger points, often associated with myofascial pain syndrome, is a contentious one in the world of physical therapy and medicine. While many practitioners believe in the existence of trigger points and find value in techniques like dry needling or manual releases to address them, there's an ongoing debate regarding their true nature and the evidence surrounding them.


Here's a breakdown of the arguments against the existence of trigger points:

  1. Lack of Standardized Diagnostic Criteria: One major issue is that there is no standardized, objective method to identify a trigger point. Most of the time, diagnosis is based on subjective clinical findings, including patient complaints and practitioner palpation. Without objective measures, it's hard to consistently define and study trigger points.

  2. Inconsistent Findings in Studies: Studies that have tried to locate and define trigger points often come up with inconsistent findings. For instance, when multiple practitioners are asked to identify trigger points on the same patient, they frequently do not agree on the locations.

  3. Microscopic Evidence is Limited: On a microscopic level, research has not consistently found any distinct or unique structures in tissues alleged to contain trigger points. This makes some researchers skeptical about their very existence.

  4. Efficacy of Treatments is Debated: While some studies have shown benefit from trigger point therapies like dry needling, others have not. Additionally, the mechanisms by which these treatments may work are not clearly understood, and there's debate over whether any observed benefits are due to the treatment itself or are simply a result of placebo.

  5. Alternative Explanations: Some argue that what are perceived as "trigger points" may just be areas of increased muscle tension or other normal variations in muscle tissue. Others believe that the pain might be due to neurological or psychological factors rather than a specific physical "point" in the muscle.

  6. Comparisons to Historical Practices: Some critics compare trigger point therapy to historical medical practices that were once widely accepted but later debunked.

However, it's worth noting that despite these criticisms, many clinicians still find value in the concept of trigger points and the associated therapeutic techniques. They argue that just because we don't fully understand the mechanism doesn't mean the phenomenon doesn't exist or that the treatments aren't beneficial.


The debate about muscle trigger points is emblematic of the larger challenges in understanding and treating pain. Pain is a complex and multifactorial experience, and there's still much we don't know about how it works and how best to address it.


Moreover, some researchers and clinicians argue that nerve entrapments provide a more plausible explanation for localized pain often attributed to trigger points. Nerve entrapments occur when a peripheral nerve is compressed or irritated, leading to pain, tingling, numbness, or muscle weakness in its distribution area. The symptoms arising from nerve entrapments can mimic those described for trigger points. Given that nerves run through and around muscles, fascia, and other soft tissues, they can be impinged upon by tight muscles or fascial adhesions. This perspective suggests that addressing the underlying nerve compression or irritation might be more effective and precise than attempting to treat a poorly-defined and debated muscle phenomenon.
