Treating Hand Tremor

Tremor is the most common movement disorder with more than 10 million Essential Tremor (ET) patients and 1 million Parkinson Disease (PD) in North America. Our research lab is currently conducting the largest and longest comprehensive Parkinson and Essential Tremor diagnostic sensor study in the world. The involuntary rhythmic movements of tremor in limbs are caused by the synchronized or alternating contraction of agonist-antagonist muscle groups. ET patients often exhibit postural and kinetic tremor while PD patients predominantly show resting tremor, however, both groups may show all these tremor symptoms during disease progression. Further ET patients exhibit tremors on both sides earlier on. The LondonMDC hopes to advance diagnostic procedure that will accelerate the recovery of tremor patients and allow for improved arm function following treatment.
