This study was aimed at the distribution, the frequencies and the correlation between the laterality of handedness, arm folding, digital interlocking, foot preference and foot overlapping. The subjects who were selected for this study were teenagers between the age group of 13 to 15 years. The study was conducted at Belgaum city which is situated in North Karnataka, India, during 2000. There is no relevant information in the literature regarding a similar study which was done in this part of the country. The population here exhibits a wide diversity in cultural and traditional lifestyles and hence this study was taken up. Personal data was collected from the subjects by providing them a questionnaire. Various tests were conducted to determine the handedness, the laterality of arm folding, digital interlocking, foot preference and foot overlapping. The data which were collected were subjected to tabulation and statistical analysis and those were tested for statistical significance. The Chi square test was used with the paired ‘T’ test. Male subjects exhibited a highly significant correlation between handedness and digital interlocking (P<0.01) Female subjects showed a highly significant correlation between handedness and digital interlocking (P<0.005)
A highly significant correlation existed between digital interlocking and arm folding in both the sexes (P<0.0001). A significantcorrelation was seen between handedness and foot overlapping (P<0.005) in both males and females. Both females and males showed a significant correlation between foot preference and foot overlapping (P<0.01).
