Investigating the AX6 inertial-based wearable for instrumented physical capability assessment of young adults in a low-resource setting

Abstract Instrumented balance and gait test are an important component of physical capability assessment in clinical examinations. This study provides insight to a new generation Open Movement inertial-based wearable (AX6, Axivity, UK) compared to a previously validated reference (AX3). The AX6 was assessed for its ability to quantify a battery of tasks that represent a composite physical capability assessment. Participants wore both wearables on the lower back (5th lumbar vertebrae) continuously throughout the testing period. No significant differences (p
