TMD symptoms were assessed using the Fonseca Anamnestic Index (FAI) and the Clinical Examination Form. Pressure pain threshold (PPT), craniovertebral angle (CVA), and masseter muscle activation (superficial EMG) were measured. Static and dynamic balance performance was analyzed with the Korebalance System. All measurement tools had established validity and reliability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Using Spearman correlation analysis, there was no significant correlation between TMD symptom severity and balance performance (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; 0.05), while a negative correlation was found between masseter muscle pressure pain threshold and balance scores (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05).

Additionally, correlations between masseter sensitivity, head posture measures, and balance performance suggest a potential neuromuscular interaction between the stomatognathic system and postural control. These findings are exploratory and hypothesis-generating, and further studies are required to clarify this potential relationship.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/njcp.njcp_490_25","type":"journal-article","created":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T06:00:15Z","timestamp":1772604015000},"page":"181-189","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Spontaneous Activation of the Masseter Muscle in Balance Tasks: The Functional Relationship Between Postural Control and the Stomatognathic System in Healthy Adults"],"prefix":"10.4103","volume":"29","author":[{"given":"M","family":"Durukan","sequence":"first","affiliation":[{"name":"Department of Physiotherapy and Rehabilitation, Institute of Health Sciences, Band\u0131rma Onyedi Eylul University, Band\u0131rma-Bal\u0131kesir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HC","family":"Guzel","sequence":"additional","affiliation":[{"name":"Department of Therapy and Rehabilitation, Physiotherapy Program, Vocational School of Health Services, Band\u0131rma Onyedi Eylul University, Band\u0131rma-Bal\u0131kesir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"R1-20260416","doi-asserted-by":"crossref","first-page":"1974","DOI":"10.38124\/ijisrt\/IJISRT24OCT1053","article-title":"Temporomandibular joint and mandibular movement: A review temporomandibular joint","volume":"9","author":"Rathee","year":"2024","journal-title":"Int J Innov Sci Res Technol"},{"key":"R2-20260416","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1186\/s12903-021-01773-z","article-title":"Temporomandibular dysfunction experience is associated with oral health-related quality of life: An Australian national study","volume":"21","author":"Hanna","year":"2021","journal-title":"BMC Oral Health"},{"key":"R3-20260416","doi-asserted-by":"crossref","first-page":"507","DOI":"10.5604\/17322693.1051002","article-title":"Muscle activity in the course of rehabilitation of masticatory motor system functional disorders","volume":"67","author":"Kijak","year":"2013","journal-title":"Postepy Hig Med Dosw (Online)"},{"key":"R4-20260416","first-page":"43","article-title":"Occlusion, sternocleidomastoid muscle activity, and body sway: A pilot study in male astronauts","volume":"24","author":"Sforza","year":"2006","journal-title":"J Craniomandib Pract"},{"key":"R5-20260416","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1016\/j.jelekin.2017.08.006","article-title":"Postural stability in subjects with temporomandibular disorders and healthy controls: A comparative assessment","volume":"37","author":"Nota","year":"2017","journal-title":"J Electromyogr Kinesiol"},{"key":"R6-20260416","doi-asserted-by":"crossref","first-page":"228","DOI":"10.1016\/j.neulet.2003.11.055","article-title":"Effects of different jaw relations on postural stability in human subjects","volume":"356","author":"Bracco","year":"2004","journal-title":"Neurosci Lett"},{"key":"R7-20260416","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/S0304-3940(02)00779-6","article-title":"Unilateral trigeminal anaesthesia modifies postural control in human subjects","volume":"330","author":"Gangloff","year":"2002","journal-title":"Neurosci Lett"},{"key":"R8-20260416","doi-asserted-by":"crossref","first-page":"378","DOI":"10.1590\/S1806-83242008000400016","article-title":"Analysis of the postural stability in individuals with or without signs and symptoms of temporomandibular disorder","volume":"22","author":"Ries","year":"2008","journal-title":"Braz Oral Res"},{"key":"R9-20260416","doi-asserted-by":"crossref","first-page":"615","DOI":"10.5005\/jp-journals-10024-3094","article-title":"Effect of occlusal splints on posture balance in patients with temporomandibular joint disorder: A prospective study","volume":"22","author":"El Zoghbi","year":"2021","journal-title":"J Contemp Dent Pract"},{"key":"R10-20260416","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1590\/bjpt-rbf.2014.0061","article-title":"Static body postural misalignment in individuals with temporomandibular disorders: A systematic review","volume":"18","author":"Chaves","year":"2014","journal-title":"Braz J Phys Ther"},{"key":"R11-20260416","first-page":"e934593","article-title":"Static balance in participants with temporomandibular joint disc displacement without reduction versus healthy participants: A cross-sectional study","volume":"28","author":"Zhang","year":"2022","journal-title":"Med Sci Monit"},{"key":"R12-20260416","doi-asserted-by":"crossref","first-page":"4473","DOI":"10.3390\/app11104473","article-title":"Is any feature of the stabilometric evaluation clinically relevant in patients with temporomandibular disorders?
