Comparison of Two Point Discrimination of Palmar Surface of Distal Phalanx of Thumb between Dominant and Non Dominant in LabourersBACKGROUND:Two point discrimination test assess the ability to perceive two points applied to the skin simultaneously applied with equal pressures. The finger tips and palm of the hand are considered to be the most sensitive parts which perceive the two-point in a small distance when compared to other parts of the body.
OBJECTIVE: To compare the tactile acuity of the thumb finger between dominant and non dominant hand n labourers.
STUDY DESIGN :Observational study.
PROCEDURE: Subjects were made to sit in a comfortable position and were asked them to close their eyes. With the aesthesiometer stimulus was given and were asked the subjects to perceive the points. Values were noted accordingly.
RESULTS: . Mean and standard deviation of dominant hand is 2.627 and 0.5205. And of non dominant hand is 2.013 and 0.4954.
CONCLUSION:This study concluded that there was a difference in tactile acuity of thumb in dominant and non dominant hand. It differesaccording to their profession and usage of dominant hand.
