Two point discrimination among school going children age between 13 years and 17 years : A Normative Research

The shortest distance between two stimuli (applied with equal pressure simultaneously) that can be measured and interpreted as two separate stimuli is referred to as two point discriminative sense. To our best knowledge there is no reference value for the two point discrimination sense for the upper extremity in high school going children .Hence, we intended to determine the same. A total of 160 (90 males and 70 females) healthy school going children aged 13 to 17 were randomly selected for the cross- sectional study. Demographics were documented and with a help of commercially available aesthesiometer two point discriminative sense was estimated in 12 areas namely, upper lateral arm (ULA), lower lateral arm (LLA), mid posterior arm (MPA), mid medial arm (MMA), mid lateral forearm (MLFA), mid medial forearm (MMFA), mid posterior forearm (MPFA), first dorsal interossei (FDI), distal of thumb (DOT), distal of long finger (DOLF), distal of short finger (DOSF), dorsal proximal long finger (DPLF).

两种刺激（同时以相等压力施加）之间可测量的最短距离，当其被解读为两个独立的刺激时，被称为两点辨别感觉。据我们所知，目前尚无针对高中生上肢两点辨别感觉的参考值。因此，我们旨在测定该值。本研究共随机选取了160名（其中男性90名，女性70名）年龄在13至17岁的健康在校儿童进行横断面研究。记录了人口统计学数据，并借助市售的触觉测量仪，在12个区域（即上臂外侧（ULA）、下臂外侧（LLA）、中后臂（MPA）、中臂内侧（MMA）、中臂外侧前臂（MLFA）、中臂内侧前臂（MMFA）、中后臂前臂（MPFA）、第一背侧骨间肌（FDI）、大拇指末端（DOT）、长指末端（DOLF）、短指末端（DOSF）、背侧近端长指（DPLF））估算了两点辨别感觉。
