Difference in Two Point Discrimination Values in Dominant and Non Dominant Hand in Healthy Young Adults

Objective: To study the Difference in Two Point Discrimination values in Dominant and Non Dominant Hand in healthy young adults.

Materials and Method: A commercially available aesthiometer was used to determine limits of twopoint discrimination sensitivity in skin areas on the subject's dominant side and nondominant side of young healthy adults.

Result: In this study, mean two-point discrimination values on right hand varied from 0.15 mm to 0.19 mm. and that of left hand varied from 0.14mm to 0.19mm.An important observation was that normative values of two-point discrimination were higher over the right hand and were lower over left hand. Also, study was done between males and females. Mean two-point discrimination values in Males varied from 0.14 mm to 0.20 mm and that of Females varied from 0.13 mm to 0.18 mm. The importance in this observation was that normative values of two-point discrimination were higher in males and were lower in females.

Conclusion: This study concluded that considerable differences do exists in normative values for Two Point Discrimination ability in the dominant and non dominant hand in a sample of normal healthy males and females
