Table 4 Associations of total C-GAITS score and subscale scores with age group, lower extremity strength, balance function, fall history, and fear of falling

From: Development and validation of Comprehensive Gait Assessment using InerTial Sensor score (C-GAITS score) derived from acceleration and angular velocity data at heel and lower trunk among community-dwelling older adults
