Sergančiųjų parkinsono ir esencialinio tremoro liga viršutinės galūnės biomechanikos tyrimas ; Research of upper limb biomechanics of subjects with parkinson‘s disease and essential tremmor

Parkinson’s disease (PD) is a common neurodegenerative disease with symptoms of bradykinesia, rest tremor, rigidity and postural instability. PL is diagnosed by a clinician who qualitatively evaluates patient’s visible symptoms during a physical exam. In addition, differentiating PD from essential tremor (ET) can be challenging because their clinical symptoms are similar. Once diagnosed, only qualitative tools such as the UPDRS are available to monitor symptom severity and disease progression. The purpose of this study is to evaluate the changes of biomechanical parameters of upper limb of subjects diagnosed either PD or ET, estimate differences and compare them with healthy subjects in facilitate a creation of an additional instrumental clinical assessment of PD subjects via biomechanical evaluation of motor function tool and develop methods and indices for differentiating PD from ET.
