Inter and Intra-rater Reliability of the Craniocervical Flexion Test by Using Modified Sphygmomanometer as a Pressure Bio-feedback
Subscribe/Renew Journal
Background and Objective: The Cranio-Cervical Flexion Test (CCFT) is a reliable clinical and research test to measure the endurance of the Deep Cranio-Cervical Flexors (DCCF) muscles via Activation Score (AS) and Performance Index (PI) by using Chattanooga Pressure Biofeedback unit (CPBU). In India, we use modified sphygmomanometer instead of CPBU for this test, but the data on reliability of the instrument is scarce. So present study was carried out to check inter and intra-rater reliability of the CCFT by using modified sphygmomanometer.
Methods: 50 subjects were selected from the age group of 17 to 22 years. For inter-rater reliability the AS and PI were measured on each subject by two different experienced Physiotherapists and For intrarater reliability the same was measured on two occasions with 7 days gape by the same therapist. ICCPearson was calculated to check inter and intra-rater reliability.
Results: For AS and PI good inter-rater reliability determined by the ICC= 0.709 and 0.752 respectively and excellent intra-rater reliability determined by the ICC=0.820 and 0.885 respectively.
Conclusion: The CCFT by using modified sphygmomanometer showed good inter-rater and excellent intra-rater reliability.
