Tremometriya is a method for investigating

• A. The speed of movement
• B. Sensory thresholds
• C. The accuracy and coordination of movements
• D. Reaction time

Answer: (C)

Tremometriya focuses on motor control by quantifying tremor to see how it affects the precision and steadiness of movements. Tremor introduces instability into small, voluntary actions, so measuring its amplitude and frequency helps determine how accurately and coordinately a person can perform fine motor tasks. This is why it best matches investigating accuracy and coordination of movements.

It isn’t primarily about how fast a movement can be made (speed of movement), nor about sensing thresholds (sensory thresholds), nor about how quickly a person responds after a stimulus (reaction time). In practice, tremor assessment is useful for tasks requiring precise, steady hands, such as detailed assembly or tool handling, and can indicate the impact of fatigue, neurological conditions, or exposures on fine motor control.
