Dermatoglyphics is the study of patterns of epidermal ridges and these patterns do not change through entire life and thus are unique features of identification. This study aimed at finding a relation between the dermatoglyphic patterns and the academic performance among the physiotherapy students of Teerthanker Mahaveer University with the sole intent of using these patterns for categorising students into above average, below average and average performance. A total of 100 physiotherapy students of 3rd and 4th year were included in the study (31 male and 69 female). The students were categorised as average, above average and below average performers on the basis of cumulative percentage of end term exams of last 2 years. The dermatoglyphic patterns were recorded using the flat-bed scanner method. Students with above average academic performance had prevalence of loop pattern (Whorls 37 %, loops 58 %, arches 4 %) while students with below average academic performance had prevalence of whorl pattern (Whorls 58 %, loops 39 %, arches 2 %) and a negative correlation of ‘atd’ angle to the academic performance was observed. Thus, these patterns may be used as adjunct tool for identifying and differentiate individuals on the basis of academic performance so that different methods and educational strategies may be made a part of the curriculum for enhancing the performance of low scoring individuals.
Keywords: Dermatoglyphics, fingerprint, atd angle, academic performance
Dermatoglyphics is the study of patterns of epidermal ridges that exist in palms and soles of an individual. The term dermatoglyphics was given by Cummins which is derivative of two words ‘derma’ which refers to ‘skin’ and ‘glyphe’ which refers to ‘curves’. These ridges get differentiated in their permanent pattern during 3rd-4th month of fetal development and do not change through the entire life except for change in dimensions in proportion to individual’s growth also, the characteristic ridge patterns of an individual are not distorted unless the epidermis is damaged to a depth of 1mm.
The dermatoglyphic patterns are analysed in different ways such as – Finger print analysis (e.g. arches, loops and whorls), Finger ridge counts, Position of the axial triradii ‘atd’ angle, No. of palmar triradii, a-b ridge count [3,4]
Studies have shown that the palm and fingerprint patterns are closely linked with brain functions as these patterns develop at the same period when brain development takes place from the ectoderm. If there is any abnormality present in the genetic trait, the children inherits it and it is reproduced in the dermatoglyphic pattern of the individual . Thus, it serves as a tool in identifying diseases having hereditary origin and is used to screen genetic anomalies. Identification is based on characteristics which are unique for an individual which may be physical, mental or psychological and derm toglyphics play a major role in identification.
Fingerprints are basically the impressions of patterns that are formed by epidermal or papillary ridges of fingertips. Fingerprint patterns are determined genotypically and do not change from birth till death. Each finger relates to a lobe of brain and each fingerprint relates to a specific learning type for e.g. Ulnar Loop pattern- Affective Learning, Radial loop pattern- Critical Thinking, Whorls are related with cognitive learning and Arch pattern is related with reflective learning.
The term achievement is used in contrast with the term ability, which implies that achievement is a result of ability or effort.[11,12] However genetic researches suggest that the differences in academic achievement of an individual are significantly heritable.[13,14,15] The heritable nature of academic achievement is as significant as the heritability of intelligence. The academia is premediated to enhance the learning ability and critical thinking by offering students with challenges. In the educational settings, intelligence has a critical role in academic performance of an individual and numerous studies have established that less IQ= Intelligence Quotient and attention deficits result in lower achievement levels.[19,20,21] Dermatoglyphic studies also help in making an individual aware of his potential, strengths and personality traits and also assists in analysing multiple intelligences and thus can be used as a way to recognize and develop talents and for providing proper educational training. Thus understanding about the factors that affect academic achievement is necessary to carry out efficient educational interventions for an individual’s optimal performance.
Thus, this study attempts to find the relation of dermatoglyphic patterns with academic performance of students in order to use dermatoglyphics as a tool for identifying and differentiate individuals on the basis of academic performance so that different methods and educational strategies can be made the part of curriculum for enhancing the performance of low scoring individuals.
MATERIALS AND METHODS
In this study 100 subjects (males 31 and females 69) were included. The subjects were taken through purposive sampling from Department of Physiotherapy, Teerthanker Mahaveer University, Moradabad; who fulfilled the inclusion and exclusion criteria. To fulfil the inclusion criteria both male and female subjects between the age of 18-25 were included. Subjects involved in any sports activity, or with any physical disability or injury on hand were excluded from this study. A consent form was signed prior to the start of the procedure to ensure safety. The subjects received detailed explanation of the aims and procedure of the study.
The fingerprints of each participant were scanned bilaterally using Canon Lide 300 flatbed scanner. The hands of the subjects were clean, and fingerprints were scanned by placing the subject’s hand against the scanning surface with fingers apart. Thumb images were scanned separately due to orientation of thumb in different plane. The dermatoglyphic patterns of the subjects were evaluated according to the classification given by Cummins and Midlow. 
For the atd angle, ‘a’, ‘t’, ‘d’ delta points were marked and joined using a marker & magnifying glass and the angle was measured using a protractor.
The students were divided in 3 categories on the basis of their academic performance: above average, average and below average. The parameter for measuring academic performance was taken as cumulative percentage of two consecutive end term exams. Students with above average performance scored 70 % and above (n= 26), students who scored between 60 % to 70 % were average performers (n=58) and students with below 60 % were categorised as below average (n=16). The data was recorded in MS excel (2016 version) and was analysed using SPSS software (version 20).
RESULTS AND DISCUSSION
The data was analysed using SPSS software. Correlation between both the variables was achieved using Pearsons test. ‘atd’ angle– Readings of ‘atd’ angles in above average students is Mean= 41.31, S.D= 3.42 of left hand and Mean= 39.77, S.D= 4.30 of right hand. In average students the readings are Mean= 41.34, S.D= 4.89 of left hand and Mean= 40.69, S.D= 5.55 of right hand. In below average students Mean= 41.13, S.D= 3.94 of left hand and Mean= 39.69, S.D= 3.36 of the right hand.
Fingerprint Patterns and Academic Performance
Correlation between readings of academic performance [Mean= 65.41, S.D= 5.90] and frequency of finger print patterns i.e. whorls [Mean= 4.26, S.D= 3.07] shows a weak negative correlation, r= -.199 that of loops [Mean= 5.24, S.D= 2.73] shows a weak positive correlation, r= .206 and arches [Mean= .51, S.D= 1.01] shows a very weak positive correlation, r= .047 i.e. the r lies from 0 to 1.
‘atd’ Angle and Academic Performance
Correlation of readings of the average percentage of marks in end term exams [Mean=65.41, S.D= 5.90] and readings of ‘atd’ angle of the dominant hand [Mean= 40.28, S.D= 4.93] is very weakly negative, r= -.015 i.e. the r value lies between 0 and 1.
ATD angle and academic achievement
Previous researches have also shown that angles <30° and >65° are associated with mental retardation.  It was observed that majority of the sample group had ‘atd’ angle in the range 34° to 47° irrespective of their academic performance.
Cesarik concluded through their study that the ‘atd’ angle decreases in males and females with super intelligence but this trend was not observed in present work as both the students with higher academic performance and lower academic performance were found in similar range of the ‘atd’ angle.  This finding is analogous to a study done by Rishi and Sharma in which they found that there is no direct relationship between the academic performance and the atd angles.
The results of the study show a very weak negative correlation between academic performance and ‘atd’ angle. The results confirm the alternative hypothesis and the correlation established is weak but the nature being negative indicates that with the increase in atd angle there may be a decrease in academic performance of the individual though it cannot be postulated as the correlation between them is very weak.
Finger print patterns and academic achievement
Analysis of finger print patterns from this study suggest that loop pattern is the most commonly occurring pattern followed by whorls and arches in both males and females which is in consonance with the previous studies.
Kanchan T et.al in their study among medical students found that loops were the most frequently occurring patterns followed by whorls and arches in both hands among males and females. While loops were predominant on index, middle and little fingers and whorls were predominant on the thumb and ring fingers.  Nayak et.al in their study among Malaysian medical students found that loops were the most dominant pattern followed by whorls. 
However, some studies suggest that whorls are the most commonly occurring pattern followed by loop and arch. Nayak et.al in their study studied about the correlation between dermatoglyphic pattern of right thumb, academic performance and learning methodologies of medical students and found that whorl pattern was the most commonly occurring pattern in their study. But they also found that the loop pattern was associated with better academic performance of students  which is similar to the results of our study that reveal the students with higher academic performance have prevalence of loop pattern while ones with lower academic performance have a prevalence of whorl pattern.
Adenowo and Dareb in their study of fingerprint patterns of medical students have found that distribution of loop pattern was the highest among the category of good students.  Mostaf in his study of association of finger print patterns with intelligence quotient reported that the loop pattern is associated with better academic performance and higher IQ.
Ourresults also show a weak negative correlation between whorls and academic performance and a very weak positive correlation between loop pattern and academic performance. The results of our study confirm the alternative hypothesis that there may be a significant correlation between fingerprint patterns and academic performance.
This study shows that there is a negative co-relation of whorl pattern to the average percentage of marks of last 2 consecutive end term exams and a significant positive co-relation of loop patterns to the average percentage which suggests that students with prevalence of loop patterns show a better academic performance than individuals with prevalence of whorl patterns.
A negative correlation of ‘atd’ angle (dominant hand) was found to the average percentage of last 2 consecutive years end term exams which was very weakly significant which suggests that individuals with greater ‘atd’ angle may have a lower academic performance but this cannot be used as a method to segregate students who tend to score higher as the relation is very weakly significant.
