Neurologists assess vibratory sense as part of routine neurological exams, typically using a 128 Hz tuning fork. The patient is asked to verbally indicate when they feel and stop feeling the vibration. However, this method is unreliable because it depends on subjective patient responses and the manual striking force of the tuning fork, leading to inconsistent results. Without a standardized measurement system, diagnosing neurological conditions becomes challenging, especially in early stages.
This new electronic vibratory sense evaluation device provides a precise, objective measurement by replacing verbal feedback with a push-button system. Patients simply press a button when they first feel the vibration and again when it stops. The device follows a pre-set vibration pattern, ensuring accurate, repeatable, and unbiased results. By eliminating examiner variability and improving diagnostic precision, this innovation is a valuable tool for neurologists, physical therapists, and medical researchers, enhancing neurological testing in clinical and remote healthcare settings.
