Background: Patients with chronic neck pain have a number of factors that could constitute a predisposition for respiratory dysfunction. However, the existing evidence is limited and not well established, and many questions such as the association of neck pain deficits with respiratory function remain unanswered. Thus, the aim of this study was to investigate whether patients with chronic neck have accompanying respiratory dysfunction and which are the neck pain deficits which principally predispose to these respiratory disturbances.Methods: In this case-control observational study, 45 patients with chronic idiopathic neck pain (>6 months, at least once per week) and 45 healthy age-, gender-, height- and weight-matched controls were voluntarily recruited. A third group of 10 patients with chronic non-spinal musculoskeletal pain was also used, but only for future reference. Participants' neck muscle strength and endurance were measured by an isometric neck dynamometer and craniocervical flexion test respectively. Range of movement was assessed by using an ultrasound-based motion analysis system. Forward head posture was assessed by obtaining lateral photographs and calculating the craniovertebral angle. Disability and neck pain intensity were assessed through the Neck Disability Index and Visual Analogue Scale. Psychological assessment was performed by using the Hospital Anxiety and Depression Scale, the Pain Catastrophizing Scale and the Tampa Scale for Kinesiophobia. Spirometry was used for assessing pulmonary volumes, flows and maximal voluntary ventilation. Respiratory muscle strength was assessed by using a mouth pressure meter. Finally, PaCO2 was assessed by using transcutaneous blood gas monitoring.Results: Patients with chronic neck pain were found to have weaker respiratory muscles than healthy controls (p0.05), whereas their peak flows were reduced (p0.3, p
