Sensorimotor reaction is assessed when performing movements by both hands. It is offered to execute one of 5 models. Models differ in quantity and sequence of visual signals’ emergence. It is also possible to estimate functional asymmetry level of left and right hand. Test result includes (for both hands): - Tap number at each stage of the test; - Total taps; - Reaction time at each stage of the test; - Average value of reaction; - Min, max values of reaction; - Coefficient of variation; - Touch duration at each stage of the test.
