Kinematic, hemiparetic stroke, simplified video processing


The purpose of the conducted study is to compare and analyse the trajectory and the kinematic variables (displacement, velocity, acceleration) of reaching activity of the upper limb part for hemiparetic stroke patient for normal side and affected side using a low cost video processing method. The research is conducted in  three different categories which are recovery, half recovery and non-recovery stroke patient group.  Six subjects were divided equally in the respective categories and they performed three trials for each reaching task, the trial was conducted by a qualified physiotherapist while the subjects were sitting on a straight-back chair or on their wheel chair. A GoPro video cameras were used to record the reaching movement in two dimensional perspective and from the recorded video, the comparison analysis was done and evaluated based on the maximum, mean and the standard deviation, kinematics performance and reaching trajectory. With this technique, was achieved implement a system that allows viewing kinematic variables as which detected in the cycle of reaching gait. The results showed a significant different between  these three group and were consistence with those reported in the previous literature
