简要总结
Neck pain is a common cause of disability worldwide, especially among middle-aged women in wealthy countries. It often occurs in episodes and can become chronic, affecting physical, psychological, emotional, and social aspects of life, which reduces quality of life for both patients and their families. Research has shown that neck pain is linked to problems with movement control, such as reduced neck mobility, increased activity in surface muscles, and poor body position awareness. These issues may lead to breathing problems because surface neck muscles are involved in inhalation. Studies have found that people with chronic neck pain have reduced lung function and altered breathing patterns compared to healthy individuals. However, no research has yet explored how respiratory endurance and balance control relate to neck pain severity. This study will assess respiratory muscle strength, endurance, and postural control in people with chronic neck pain. Participants will be divided into groups based on the severity of their neck disability, and their respiratory and balance measurements will be compared to healthy individuals. The goal is to understand whether worsening neck disability is associated with greater respiratory problems.
详细描述
This study designed as cross-sectional study. Aim
The aim of this study is to investigate the presence of respiratory dysfunction in individuals with chronic non-specific neck pain by evaluating respiratory muscle strength, endurance, and postural control. It also aims to classify the data obtained according to the severity of neck disability and to determine whether respiratory dysfunction is associated with the severity of neck involvement.
Research Hypotheses
H0: There is no difference in respiratory muscle strength, endurance, and postural control parameters between individuals with chronic non-specific neck pain and asymptomatic individuals.
H1: There is a difference in respiratory muscle strength, endurance, and postural control parameters between individuals with chronic non-specific neck pain and asymptomatic individuals.

结局指标
主要结局
Measurement of Respiratory Muscle Endurance
时间窗: 4 weeks
Respiratory muscle endurance refers to the ability of the respiratory muscles to sustain performance during prolonged or repetitive contractions. This parameter is typically assessed with specific endurance tests and may vary depending on the measurement protocol. During the endurance test, the participant sustains respiratory muscle activity under a given load or intensity for a specified duration, and performance values are recorded.
Assessment of Cervical Disability:
时间窗: 4 weeks
Cervical disability will be evaluated using the Turkish version of the Neck Disability Questionnaire. This is one of the most commonly used questionnaires for neck pain. It is used to assess the patient's current condition and progress during treatment. The questionnaire consists of 10 sections completed by the patient, covering pain, personal care, lifting heavy objects, reading, headaches, concentration, work, driving, sleeping, and recreation. Each section is scored from 0 (no disability) to 5 (complete disability). The total score ranges from 0 (no disability) to 50 (total disability). An increase in the score indicates greater disability, while a decrease indicates improvement. Based on the total score, disability is classified as follows: 0-4 points (0-8%) no disability, 5-14 points (10-28%) mild disability, 15-24 points (30-48%) moderate disability, 25-34 points (50-64%) severe disability, and 35-40 points (70-100%) complete disability (Vernon et al., 1991; Telci et al., 2009).
Maximum Expiratory Pressure
时间窗: 4 weeks
Maximum Expiratory Pressure is the intraoral pressure measured during maximum expiration against a closed airway valve. For the measurement, the participant first performs a maximum inspiration. Then, the airway valve is closed, and the participant performs maximum expiration, maintaining it for 1-3 seconds. The highest value out of three attempts will be selected and recorded in cmH₂O. Results will be expressed as a percentage of normal reference values calculated according to age and gender.
respiratory function test
时间窗: 4 weeks
Lung function will be measured with a portable spirometer. The test will record forced vital capacity, the amount of air exhaled in one second, their ratio, and peak flow. Results will be given in liters and compared to predicted normal values. The test follows official guidelines and uses sterilized, personal mouthpieces to ensure safety.
Maximum Inspiratory Pressure
时间窗: 4 weeks
Maximum inspiratory mouth pressure is the intraoral pressure measured during maximum inspiration against a closed airway valve. For the measurement, the participant is asked to perform a maximum expiration first. Then, the airway valve is closed, and the participant performs a maximum inspiration, maintaining it for 1-3 seconds. The best value out of three attempts will be selected and recorded in cmH₂O. Results will be expressed as a percentage of normal reference values calculated according to age and gender.
