From: A comprehensive scheme for the objective upper body assessments of subjects with cerebellar ataxia
Instrumented version of the upper limb assessments and the movement waveform of a control and a patient diagnosed with CA. a Finger Chase (ballistic, FCT) using Kinect© system. b I. An IMU sensor with tri-axial accelerometer directions (Ax,Ay,Az) with a gyroscope directions (Gx,Gy,Gz) b II. Sensor placement around the wrist b III. Sensor placement around the palm. Testing with the IMU system denoting the direction of the primary movement; movement along the direction of effective axis in order to accomplish the task objectives: c Finger tapping (FTT), d Finger to nose (FNT), e dysdiadochokinesia (DDKT)
