Brief Summary

This cross-sectional study investigates neck-related disability in individuals with chronic neck pain by examining the combined influence of temporomandibular disorders, sleep quality, and cervical sensorimotor function within a single analytical model. Although these factors have previously been investigated separately, their combined contribution to disability has not been sufficiently explored. By integrating these clinical variables within one framework, our study aims to provide a multidimensional clinical perspective relevant to assessment and rehabilitation planning in musculoskeletal practice. Given the increasing clinical recognition of the interaction between temporomandibular and cervical systems, this study may help clinicians better understand multidimensional contributors to disability in chronic neck pain.

Conditions

Neck Disability; Temporomandibular Disorders (TMD)

Keywords

Neck pain; Temporomandibular disorders; Sensorimotor control; Proprioception

Outcome Measures

Primary Outcomes (1)

• neck disability

  Neck disability was evaluated by The Neck Disability Index (NDI) total score The NDI consists of 10 questions in total, and each question evaluates a different area of daily life. Each question is scored between 0 and 5 points: 0 = no problem at all, 5 = maximum limitation. The total score range can be: Minimum: 0 and Maximum: 50.

  Primary outcome (NDI) was measured once at baseline during the cross-sectional assessment.

Secondary Outcomes (1)

• Sleep quality

  at baseline

Other Outcomes (2)

• Cervical Proprioception, Deep Neck Flexor Endurance, and Posture

  at baseline

• Deep neck flexor muscle endurance

  at baseline

Study Arms (2)

TMD-positive

TMD-negative

TMD-negative

Eligibility Criteria

• Age: 18 Years - 55 Years
