WebSensitivity and specificity mathematically describe the accuracy of a test which reports the presence or absence of a condition. If individuals who have the condition are considered "positive" and those who don't are considered "negative", then sensitivity is a measure of how well a test can identify true positives and specificity is a measure of how well a test can … WebVibratory. Vibratory sensation ( pallesthesia) is one of the sensory modalities of the DCML system. It is tested by using a 128 Hz tuning fork and placing the vibrating instrument over a bone or boney prominence. By varying the force of vibration and comparing the patient to yourself you can detect any deficits.
