Inter-rater and intra-rater reliability of head-mount laser device on assessing cervical spine proprioception in patients with cervicogenic headache . International Journal of Research in Medical Sciences. 2024 Oct; 12(10): 3698-37022320-60712320-6012https://imsear.searo.who.int/handle/123456789/246849Background: Relationship exist between the occurrence of cervicogenic headache (CGH) and head posture, due to a reduction in proprioception from the cervical spine. Active joint position sense of the cervical spine can be assessed using head-mount LASER device. This study evaluated the reliability of the head-mount LASER device in assessing cervical proprioception in adults with CGH. Methods: A total of 50 adults of both genders with a clinical diagnosis of CGH were recruited for the study. The assessment for cervical proprioception was done using the device using a pre-determined test protocol, by two different therapists. The tests were repeated on the next day as well. The accuracy of relocation of the LASER pointer from the pre-determined target spot were evaluated in centimeters, during both flexion and extension. Results: The study found good inter-rater reliability for flexion (ICC=0.888; 95% CI: 0.743 to 0.945) and extension (ICC=0.873; 95% CI: 0.754 to 0.931), and good to excellent intra-rater reliability for the device (ICC for flexion and extension being 0.952 and 0.951, respectively). Conclusions: This study concluded that head-mount LASER device can be used as a clinical tool in assessing cervical proprioception, and demonstrated good inter-rater and intra-rater reliability when used on patients with cervicogenic headache.Cervical proprioceptionCervicogenic headacheHead-mount LASER deviceInter-rater reliabilityIntra-rater reliabilityJournal ArticleIndiaRVS College of Physiotherapy, Coimbatore, Tamil Nadu, India; KMCH College of Physiotherapy, Coimbatore, Tamil Nadu, IndiaRVS College of Physiotherapy, Coimbatore, Tamil Nadu, IndiaRVS College of Physiotherapy, Coimbatore, Tamil Nadu, IndiaKMCH College of Physiotherapy, Coimbatore, Tamil Nadu, IndiaKMCH College of Physiotherapy, Coimbatore, Tamil Nadu, IndiaMother Theresa Post Graduate and Research Institute of Health Sciences, Puducherry, IndiaDepartment of Physiotherapy, National Institute of Mental Health and Neuro-Sciences, Bengaluru, Karnataka, India
