Accessory Inspiratory Muscles in Chronic Neck Pain

NCT07782099 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 10

Last updated 2026-08-24

No results posted yet for this study

Summary

This cross-sectional case-control study aims to investigate the ultrasonographic structural and functional characteristics of accessory inspiratory muscles in individuals with chronic non-specific neck pain and compare them with healthy controls. In addition, the relationships between accessory inspiratory muscle characteristics, diaphragm function, respiratory muscle strength, and pulmonary function parameters will be examined. The findings may improve understanding of the respiratory involvement associated with chronic neck pain and contribute to more comprehensive assessment strategies.

Conditions

  • Chronic Neck Pain
  • Healthy (Controls)

Interventions

DIAGNOSTIC_TEST

Diaphragm Ultrasonography

Diaphragm thickness was assessed by ultrasonography while the participant was in a standardized position. Measurements were obtained at the end of expiration and during maximal inspiration.

DIAGNOSTIC_TEST

Anterior Scalene Muscle Ultrasonography

Anterior scalene muscle thickness was assessed by ultrasonography while the participant was in a standardized position. Measurements were obtained at rest and during maximal inspiratory effort.

DIAGNOSTIC_TEST

Upper Trapezius Muscle Ultrasonography

Upper trapezius muscle thickness was assessed by ultrasonography while the participant was in a standardized position. Measurements were obtained at rest and during maximal inspiratory effort.

DEVICE

Maximal Inspiratory Pressure Measurement

Maximal inspiratory pressure was measured using a respiratory pressure measurement device. The participant performed a maximal inspiratory effort against an occluded airway after complete expiration. Repeated measurements were performed with appropriate rest intervals.

DEVICE

Maximal Expiratory Pressure Measurement

Maximal expiratory pressure was measured using a respiratory pressure measurement device. The participant performed a maximal expiratory effort against an occluded airway after maximal inspiration. Repeated measurements were performed with appropriate rest intervals.

DEVICE

Pulmonary Function Testing

Pulmonary function testing was performed using spirometry while the participant was in a standardized seated position. The participant completed maximal forced expiratory maneuvers following standardized instructions, and technically acceptable measurements were recorded.
