Gluteal syndrome (GS), a new low-back-pain subtype mimicking sciatica, has been included in the 11th Revision of the International Classification of Diseases (ICD-11). Low back pain is a symptom, not a disease, and the main problem associated with it is pain complexity. A plausible pain generator of gluteal syndrome is the central sensitization process and the therapeutic target area, which are trigger points located within the gluteal muscles. It has been hypothesized that dysregulated immune and autonomic nervous systems (ANS) are involved in central sensitization development. Changes in ANS regulation, mainly through the sympathetic branch, provoke nociceptor activation indirectly by a vasoconstriction–vasodilatation imbalance, or directly by sympathetic–nociceptor activation resulting in widespread pain, hyperalgesia, and allodynia. The minimally invasive procedure (MIP) uses thermography to confirm a completely new biological phenomenon, which suggests a pathological autonomic response to noxious stimuli and can possibly become an objective marker of some nociplastic pain subtypes related to trigger points. This review provides the biological and technical rationale for the automation of the MIP—a possible future diagnostic tool for an objective gluteal syndrome confirmation.
