Parkinson’s disease patients face numerous motor symptoms that eventually make their life different from those of normal healthy controls. Out these symptoms, tremor and bradykinesia, are relatively prevalent in all stages this disease. The assessment is usually performed by traditional methods where the accuracy results still an open question.
