Abstract
Gait analysis is an important method to evaluate individuals with motor disabilities. Accelerometer and inertial sensors have been an alternative for kinematic gait parameters detection, since they are easy-to-use, affordable, and low-cost. The objective of this study is to verify the possibility of using accelerometer to identify kinematic gait parameters of healthy and stroke individuals. Fourteen volunteers (average age 29 ± 4 years) participated of the first experiment, using one biaxial accelerometer placed on the lateral malleolus, and 5 volunteers (average age 26 ± 3 years) of the second experiment, using the accelerometer located on L2 vertebrae. One stroke individual (48 years) participated in both experiments. The accelerometer placed on the ankle identifies two gait phases of a single leg, and when placed on the lower back, data from both legs can be obtained. Some pathologic gaits, such as stroke, present kinematic asymmetry, which requires both limbs to be analyzed. In those cases, the lower back placement can provide greater amount of data using the same sensor and processing.
