Journal ArticleDOI
Gait Phase Detection for Normal and Abnormal Gaits Using IMU
TL;DR: The proposed method may provide human-understandable insights into the shank’s angular velocity and acceleration to assist clinicians to evaluate the patients’ gaits and is compared with an existing method that uses force sensitive resistors placed under the foot.
Proceedings Article
A Gyroscope Based Accurate Pedometer Algorithm
TL;DR: This approach demonstrated accuracies above 96% even at slow walking speeds on flat land, above 95% when walking up/down hills and above 90% when going up/ down stairs, which has supported the concept that the gyroscope can be used efficiently in step identification for indoor positioning and navigation systems.
Proceedings ArticleDOI
Human gait phase recognition based on thigh movement computed using IMUs
Nimsiri Abhayasinghe,Iain Murray +1 more
TL;DR: This paper presents a method to recognize all major phases of human stride cycle during walking from movement of one thigh, using a single inertial measurement unit (IMU) placed in a trouser pocket of the subject.
Journal ArticleDOI
Validation of foot pitch angle estimation using inertial measurement unit against marker-based optical 3D motion capture system
TL;DR: The results of a systematic validation procedure to validate the foot pitch angle measurement captured by an IMU against Vicon Optical Motion Capture System, considered the standard method of gait analysis are reported.
Journal ArticleDOI
Classification of foot drop gait characteristic due to lumbar radiculopathy using machine learning algorithms.
TL;DR: It is demonstrated that the combination of inertial sensors and machine learning algorithms, provides a promising and feasible solution to differentiating L5 radiculopathy related foot drop from normal walking gait patterns.
