Vibration Sense


Also found in: Dictionary, Thesaurus, Medical, Legal.

Vibration “Sense,”

 

a sensation arising under the influence of the successive alternation of mechanical (primarily sonic) stimuli that vary in intensity and frequency. The vibration “sense” is distinct from the sensation of pressure or touch. Vibration is perceived by mechanoreceptors, particularly the Pacinian corpuscles, which are located in various parts of the body (near blood vessels and in the periosteum and hypodermic tissue); they are especially numerous in the wrists and the soles of the feet. Various devices that transform sonic and visual signals into mechanical oscillations permit deaf or blind persons to increase the volume of information received from their environment by means of the vibration “sensed.”

In all, seven sensori-motor measures were identified as significant predictors for one or more of the gait parameters: low-contrast visual acuity, touch, vibration sense, vestibular X test writing performance, quadriceps strength, reaction time and sway.
Touch was included in the multiple regression equation when predicting sway with eyes open, whilst proprioception was included when predicting sway with eyes closed, with vibration sense included in both equations.
After controlling for age, increased sway when standing on a firm surface was associated with poor tactile sensitivity, vibration sense, proprioception, strength and reaction time, but not with the visual or vestibular function measures.
There are limitations to the method, however, in that the compliant surface does not eliminate peripheral input as shown by the positive significant correlations between proprioception, touch and vibration sense and sway on foam.

Vibration sense testing was performed with a 128-Hz tuning fork and documented by a single investigator using an 8-point numeric scale.
A value of 8/8 or 7/8 (almost no residual vibration of the tuning fork) is considered to be normal, and lower values (high levels of vibration of the tuning fork) indicate an impairment of vibration sense.
Vibration sense was tested 3 times at each measurement at the terminal inter phalangeal joint of the great toe and the medial malleolus and calculated as the mean.
Moreover addition of clonidine also improves the quality of blockade as evident by loss of vibration sense.
