Sensory Thresholds: The minimum amount of stimulus energy necessary to elicit a sensory response.Thermosensing: The sensation of cold, heat, coolness, and warmth as detected by THERMORECEPTORS.Sensation: The process in which specialized SENSORY RECEPTOR CELLS transduce peripheral stimuli (physical or chemical) into NERVE IMPULSES which are then transmitted to the various sensory centers in the CENTRAL NERVOUS SYSTEM.Pain Threshold: Amount of stimulation required before the sensation of pain is experienced.Touch: Sensation of making physical contact with objects, animate or inanimate. Tactile stimuli are detected by MECHANORECEPTORS in the skin and mucous membranes.Vibration: A continuing periodic change in displacement with respect to a fixed reference. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Fecal Incontinence: Failure of voluntary control of the anal sphincters, with involuntary passage of feces and flatus.Peripheral Nervous System Diseases: Diseases of the peripheral nerves external to the brain and spinal cord, which includes diseases of the nerve roots, ganglia, plexi, autonomic nerves, sensory nerves, and motor nerves.Pressure: A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Manometry: Measurement of the pressure or tension of liquids or gases with a manometer.Pain Measurement: Scales, questionnaires, tests, and other methods used to assess pain severity and duration in patients or experimental animals to aid in diagnosis, therapy, and physiological studies.Pain: An unpleasant sensation induced by noxious stimuli which are detected by NERVE ENDINGS of NOCICEPTIVE NEURONS.Hot Temperature: Presence of warmth or heat or a temperature notably higher than an accustomed norm.Differential Threshold: The smallest difference which can be discriminated between two stimuli or one which is barely above the threshold.Auditory Threshold: The audibility limit of discriminating sound intensity and pitch.
