About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age between 18 and 65 years

Presence of chronic non-specific neck pain for at least 3 months

Non-traumatic origin of neck pain

Pain intensity ≥ 3 on the Numeric Pain Rating Scale (NPRS) or Visual Analog Scale (VAS)

Disqualifiers

History of whiplash injury or cervical trauma

Previous cervical spine surgery

Cervical radiculopathy or neurological deficits

Chronic respiratory diseases (e.g., COPD, asthma)

Trial population

The study population will consist of adults aged 18 to 65 years. The case group will include individuals with chronic non-specific neck pain lasting at least 3 months, while the control group will consist of age-matched healthy volunteers without neck pain during the previous 3 months. Participants will be recruited from the Physical Medicine and Rehabilitation outpatient clinic and the surrounding community.

Treatments tested in this trial

  • Diaphragm Ultrasonography

    Diagnostic test

    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.

  • Anterior Scalene Muscle Ultrasonography

    Diagnostic test

    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.

  • Upper Trapezius Muscle Ultrasonography

    Diagnostic test

    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.

  • Maximal Inspiratory Pressure Measurement

    Device

    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.

  • Maximal Expiratory Pressure Measurement

    Device

    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.

  • Pulmonary Function Testing

    Device

    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.

Maximal Inspiratory Pressure (MIP)

Maximal inspiratory pressure will be measured using a respiratory pressure measurement device. Participants will perform a maximal inspiratory effort against an occluded airway after complete expiration. The highest technically acceptable value will be recorded in cmH₂O. Higher values indicate greater inspiratory muscle strength.

Forced Vital Capacity (L)

Forced vital capacity will be measured using spirometry during a maximal forced expiratory maneuver performed after maximal inspiration.
