A Study to Analyse the Relationship Between Visuospatial Ability and Hand Function in Normal Individuals

Abstract

Introduction: Conditions like Stroke and Cerebral palsy patients have disturbance of both hand function and visuospatial ability. The parietal cortex is involved in visual control of hand movement. In bilateral posterior parietal lesions, subjects may have easy in object recognition but cannot point to it.
Objectives: This study intends to analyse the relationship between visuospatial ability and hand function in normal individuals based on the above background. The aim of this study is to analyse the relationship between visuospatial ability and hand function in young individuals.
Methods: 100 subjects were participated with the age of 20-30 years included. They performed mirror drawing task with both hands and answered ABILHAND questionnaire.
Results: The data has been analyzed by the SPSS 22nd version software. The Nonparametric correlation test [Kendall’s tau_b] was used for analysing the derived data for time taken and errors committed in completing the visuospatial tasks and hand function. The right side error committed for completing visuospatial task decreases the right side hand function will increases it is statistically significant. The left side error committed for completing visuospatial task increased the left side hand function decreased but it is not statistically significant
Conclusions: It has been concluded that visuospatial ability has a more significant impact over hand function. As visuospatial ability components should also be considered in rehab protocol for various motor and function impairment of hand.
