Tender Points and Trigger Points – Differences and Similarities

Abstract

Objectives: There are two major types of non-inflammatory myalgia conditions, namely fibromyalgia syndrome [FMS] and myofascial pain syndrome [MPS]. In both cases, identifying the so-called tender points characteristic of FMS and trigger points characteristic of MPS is of key importance when making a diagnosis.

Findings: The two syndromes are very similar and the above-mentioned points are difficult to distinguish during examination, which often leads to wrong diagnosis and, consequently, therapy failure. Additional difficulties are caused by the lack of coherence of nomenclature; in the literature the terms “tender point” and “trigger point” are used interchangeably. Moreover, some centers question the existence of FMS and MPS as separate pain entities.

Conclusion: Although the differences in pathophysiology, the two syndromes are often mistaken. Further investigation and new assessment tools are needed to improve outcomes in both entities.
