Clinical Trial Summary

Tactile localization stimuli are fundamental in forearm to the somatosensory perception.Tactile localization reverse the touch internal organization of the forearm and in the normal development of children.It is helpful in quick estimation of tactile localization among the children in the age group, eight to thirteen years.Study design is cross-sectional study it is conducted from September 2017 to April 2019 and use stratified random sampling. subject recruitment is healthy school going children of age group between eight and thirteen year will be included in this study.The procedure will be explained to the children's before starting the test. Ascent will be obtained from the participant. Anthropometrics will be measured before beginning the procedure. The acuity of TL will be determined by the point-to-point tactile localization (PPTL) technique. For performing PPTL, the child will be seated and the examiner will locate a point on the participants forearm of the blinded child by a black pen marker. Then the child will be asked to relocate the point with the help of red pen marker in blindfolded state. The distance between black point and red point (in cm) will be noted this distance will be measure by measuring tape as the acuity of tactile localization. Mean of three readings will be used for estimating the normative reference value of tactile localization by PPTL technique.

Description:

For performing Point to Point Tactile Localization, the child will be seated and the examiner will locate a point on the forearm of the blinded child by a black marker pen. Then the child will be asked to relocate the point with the help of red marked in blindfolded state. The distance between black point and red point (in cm) will be noted as the acuity of tactile localization. 15 areas in upper limb will be selected and PPTL will be performed on them. The fifteen areas are, phalanges of the palmer area of the little finger (palm 1), phalanx of the middle finger of the Palmer area (palm 2), phalanx of the thumb area of palm (palm 3), first dorsal interosseous (palm 4), mid last part of the forearm (forearm 1), middle of the medial forearm (forearm 2), medial side of the forearm (forearm 3), the lower portion of the arm (arm 1), middle posterior of arm (arm 2), lateral side of upper arm (arm 3), lower portion of medial arm (arm 4), middle portion of arm (arm 5), the median upper arm (arm 6), lower side arm (arm 7), and upper side of arm (arm 8). Mean of three readings will be used for estimating the normative reference value of tactile localization by PPTL technique.
