Analysis ofHuntingtonʹs patient gait by imaging systems during three years

Introduction: Different studies have been done on Huntingtonʹ s disease which mostly put emphasis on clinical observations and genetic tests. Direct observation is : the method with the lowest cost however it problem is giving qualitative results which do not lead to careful diagnosis. Utilizing engineering methods of motion analysis, different movement disorders of these patients can be verified carefully which between all of them gait disorders are of great importance and are studied in this paper. Methods & materials: In this research to achieve quantitative and precise gait analysis of Huntingtonʹs patients, an imaging system has been used and by that, gait of a patient with Huntingtonʹs has been assessed for three years with the interval of two months. Results: With the use of mentioned system, angular changes of jointʹs lower extremities and time of movement are measured as kinematic parameters. Conclusion: Experiment results il1ustratd that these parameters can be used to diagnose and evaluate disea e process, which means during disease progress, magnitude of changes of jointʹ . angles in lower extremities decreases and time of movem nt performance increases.
