Main Article Content
Abstract
Introduction: Cervical spine instability is a disorder in which the cervical spine cannot maintain its normal alignment under physiological loads to protect the blood vessels, nerves, and spinal cord from damage or irritation. The symptoms of cervical spine instability present include neck pain, dizziness, inability to prolong holding the head, and impaired movement. The more severe symptoms can cause cervical spondylolisthesis. Therefore, it is necessary to have an early screening tool for cervical spine instability to avoid complications and consequences. However, this screening tool is limited in its use by language for the Thai therapist who is a non-English speaker.
Objective: The primary objective of this study was to translate the 16 items of the cervical spine instability screening tool from English to the Thai language. The secondary objective was to test the content validity of the cervical spine instability screening tool Thai version.
Methods: The cervical spine instability screening tool was translated from the original English language into the Thai language by the process of cross-cultural adaptation. Then, the content validity was tested by using the index of Item-Objective Congruence (IOC) which was obtained by a group of expert. 5 independent experts with clinical experience more than 5 years in treating neck pain patients including 3 physiotherapists and 2 orthopedic surgeons.
Results: The IOC index rating by 5 independent experts reached an average of 0.90 (range 0.60-1.00).
Conclusion: The screening tool (Thai version) for patients with cervical instability has satisfactory content validity (average IOC = 0.90) for application in clinical practice.
