Normative Reference Value of Double Simultaneous Stimulation in Asymptomatic Young Adults
This research is conducted to estimate the Normative Reference Value (NRV) of Double Simultaneous Stimulation (DSS) in healthy young adults. This study focuses on two aspects of DSS, tactile and visual. Tactile stimulations were given with objects of different textures like sandpaper, satin cloth etc., and visual stimulation were given on laptop screen with likely similar alphabets. Three responses (duration) were documented for each type stimulation in which subject appreciates the type of stimulation. Mean of each type of stimulation was calculated to determine the NRV.
Steps to reproduce
For tactile stimulation, objects of different textures like sand-paper, cotton cloth, satin, velvet, bubble wrap, jute were used. These objects were touched bilaterally concurrently on hands with blindfold. Subjects were asked to appreciate the type of texture and as soon as subjects identifies the texture time was documented with the help of stop watch by an assistant. For visual aspect of DSS, various alphabets which are likely similar of specific height and width with red/green color were displayed on laptop screen with black background at a distance of 100 meters from the subject. Subjects were asked to identify both alphabets and their color and time was documented.
