Abstract
10 m fastest gait examination is conducted to investigate the sign of mild cognitive impairment. Inertial sensors composing of accelerometer and gyro sensor are attached on both left and right tiptoes over the shoes. Subjects with age ranges from 19 to 93 were asked to walk at their fastest speed while the inertial sensors measure the acceleration and angular velocity of the toes. Data from men (68.0±10.7 years old, n=634) and women (54.5±8.6 years old, n=856) are used to calculate gait parameters such as stride length, gait rate, gait velocity, toe’s angle, toe’s height, and percentage of swing phase. MMSE (Mini-Mental State Examination) is conducted on all subjects and correlations coefficients R of the MMSE score with parameters including gait parameters are calculated. For men, parameter with highest correlation is age followed by fastest 10 m walking time and walking velocity with value of R is 0.50, 0.38, and 0.38 respectively. For women, parameter with highest correlation is walking time followed by age and walking velocity with value of R is 0.35, 0.35, and 0.34 respectively.
