Investigation of Method for Selective Induction of AVR, TVR, and KI

It is known that vibratory stimulation to tendons can elicit various reflexes and illusions. For example, when vibratory stimulation is applied to the flexor tendon of the wrist, phenomena such as kinesthetic illusion (KI), where the wrist feels as if it moves in the extension direction without actual movement, antagonist vibratory response (AVR), where the wrist moves in the extension direction, tonic vibration reflex (TVR), where the wrist moves in the flexion direction, or no phenomenon at all, may occur. However, previous studies have not identified a method to selectively elicit these phenomena. This study investigates methods for selectively eliciting these phenomena.
