Summary
This study found no link between neck disability and mandibular range of motion in women. Interventions for the temporomandibular joint do not impact neck function, and vice versa.
Area of Science:
- Biomechanics
- Neurology
- Orthodontics
Background:
- The mandibular and cervical systems exhibit close neurological and biomechanical interactions.
- Understanding the relationship between neck disability and mandibular range of motion is crucial for comprehensive patient care.
Purpose of the Study:
- To investigate the association between neck disability and mandibular range of motion (ROM).
- To determine if interventions targeting the temporomandibular joint affect neck disability and vice versa.
Main Methods:
- Fifty-two women (18-40 years) were grouped based on Neck Disability Index (NDI) and Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) scores.
- Mandibular ROM was assessed using RDC/TMD criteria.
- Statistical analyses included ANOVA, Tukey's test, and Spearman's correlation.
Main Results:
- Significant differences in mandibular opening ROM were observed between healthy volunteers and those with temporomandibular disorders (TMD) without neck disability (p=0.009).
- Significant differences were also found between those with TMD without neck disability and those with neck disability without TMD (p=0.024).
- No significant correlation was found between mandibular ROM and NDI scores (p > 0.05).
Conclusions:
- No association exists between mandibular ROM and neck disability in the studied population of university women.
- Clinical interventions for temporomandibular joint flexibility do not appear to influence neck disability, and conversely, neck interventions do not affect temporomandibular joint function.
