AbstractIntroduction: The quantification of knee range of motion is a clinically relevant measurement in the healthcare setting, as its decrease can alter activities of daily living. Collecting reliable measurements of the range of motion allows us to evaluate the reliability of interventions, or the severity of the pathology. The objective of this study was to obtain the intra- and inter- rater reliability of a protocol for the knee the range of joint motion, measured with an inertial sensor in asymptomatic subjects. Methods: The range of motion of 32 asymptomatic knees was measured. Two measurement sessions were performed by two different evaluators. A total of 8 measurements were made in each session: 2 measurements for flexion in supine decubitus position, 2 measurements for extension in supine decubitus, 2 measurements for flexion in standing position and 2 measurements for extension in standing position. Results: For inter-rater reliability, good results were achieved, with an ICC > 0.79 for all movements. The obtained data for intra-rater reliability in all the movements was excellent, with an ICC > 0.88. Conclusion: This study obtained excellent inter-rater and intra-rater reliability for healthy subjects.
