Knee kinematics during gait is an important assessment tool in health-promotion and clinical fields. This study aimed to determine the validity and reliability of a wearable goniometer sensor for measuring knee flexion angles throughout the gait cycle. Twenty-two and seventeen participants were enrolled in the validation and reliability study, respectively. The knee flexion angle during gait was assessed using a wearable goniometer sensor and a standard optical motion analysis system. The coefficient of multiple correlation (CMC) between the two measurement systems was 0.992 +/- 0.008. Absolute error (AE) was 3.3 +/- 1.5 degrees (range: 1.3-6.2 degrees) for the entire gait cycle. An acceptable AE (<5 degrees) was observed during 0-65% and 87-100% of the gait cycle. Discrete analysis revealed a significant correlation between the two systems (R = 0.608-0.904, p <= 0.001). The CMC between the two measurement days with a 1-week interval was 0.988 +/- 0.024, and the AE was 2.5 +/- 1.2 degrees (range: 1.1-4.5 degrees). A good-to-acceptable AE (<5 degrees) was observed throughout the gait cycle. These results indicate that the wearable goniometer sensor is useful for assessing knee flexion angle during the stance phase of the gait cycle.
