Surface EMG to Measure Paratonia in Dementia

The behavioral paradigm consist of a passive and active movement condition. Both conditions consist of arm movements along the entire range of motion by moving the distal segment of the arm towards the proximal segment and back under varying conditions. In the 'passive' condition, this arm movement will be performed by researcher at 3 different velocities in sinusoidal (continuous) and linear (non-continuous) fashions whereas in the 'active' condition, the participant will be instructed to move the arm in one velocity under internal and external focus of attention.
