Inertial Sensors and Wavelets Analysis as a Tool for Pathological Gait Identification

The human gait analysis by using wavelets transform of signal obtained from six inertial ProMove mini sensors is proposed in this work. The angular velocity data measured by the gyro sensors were used to estimate the translational acceleration in the gait analysis. As a result, the flexion - extension of joint angles of the knees were calculated for healthy people and with impaired locomotion system. After measurements we propose to use one of wavelet transform (wavelet type) in order to analyze the signals, indicate a characteristic feature and compare them.

Human Gait Feature Detection Using Inertial Sensors Wavelets

The human gait analysis by using wavelets transform of signal obtained from six inertial ProMove mini sensors is proposed in this work. The angular velocity data measured by the gyro sensors is used to estimate the translational acceleration in the gait analysis. As a result, the flexion–extension, the adduction–abduction joint angles of the hips, flexion–extension of the knees and dorsi and plantar flexion of the ankle are calculated. After measurements we propose to use one of wavelet transform (wavelet type) in order to analyze the signals, indicate a characteristic feature and compare them.

Body part accelerations evaluation for chosen techniques in martial arts

The authors have applied microelectromechanical systems (MEMS) for the motion analysis in sports activities by attaching them onto the judoist body segments. The inertia sensor has been attached onto the most often injured body region as head, torso and legs. MEMS can measure acceleration and provide real-time feedback to judoists so they can perfect their form. Therefore, authors proposed the judoist’s skill evaluation and techniques harmfulness, extracting the body segment accelerations. The purpose of this study was to assess the acceleration profile of judoka during ukemi. Ukemi in a literary is the technique that must incorporate the least chance for injury during falling. When judoist falls to the mat, the more area of impact it has, the less damage it receives.
