Study to identify the normative values of left-right discrimination for Indian population aged 20 to 60 years

Abstract

Background: Graded Motor Imagery is a rehabilitation tool to manage pain and improve function. Left right discrimination is one of the component of GMI. People in pain often reduce the ability to identify left and right image of their painful parts .When viewing picture of the body parts they are less slow and less accurate at determining whether the image is left or right than someone without pain.Objective: The objective of the study is to identify the response time and accuracy in both left and right side of the body by performing the left right discrimination test using the Recognize app for shoulder, hand, knee and foot. And identifying the difference between male and female.Method: A total of 279 participants were included in the study based on the selection criteria. All the participants completed left right discrimination test for 30 hand image, 30 shoulder image, 30 foot image and 30 knee image in 10 inch tablet tablet using recognize application where accuracy and response time (RT) were noted down.Outcome Measures: Recognise mobile application version 1.0.6 by NoigroupResults: The baseline characteristics age and gender wise results was calculated .The normative response time and accuracy for hand image is 2.43 sec with accuracy of 78%. The normative response time and accuracy for shoulder image is 1.90 sec with accuracy of 83.9%. The normative response time and accuracy for foot image is 1.90 sec with accuracy of 87.9%. The normative response time and accuracy for knee image is 2.95 sec with accuracy of 70.5%.Conclusion: Our study present data in both genders we have found out that in some age category women took longer response time and the accuracy to identifying left right image in less in compared to the men. Overall performance was done and compare with healthy participants. If the further left right discrimination research done on subject with affected body parts this research provide additional data and arguments for maintaining activity in context to pain rehabilitation and self-management.
