Left Hand Length Research Articles

Preliminary study on hand dimensions as potential predictors of female populations native to forest and savanna zones in Ghana.

The hand is a versatile structure that performs numerous tasks, ranging from exertion of great force such as grip, pinch and torque to execution of precise fine motor skills. The aim of current study was to undertake a preliminary study on hand dimensions as potential predictors of female populations native to the forest and savanna zones of Ghana. A total of one hundred (100) female students aged between 17 and 24years were recruited into this study, comprising of 53 native to the forest zone and 47 native to savanna zone of Ghana between 12th June to 27th July, 2023 at the Department of Anatomy, School of Medicine and Dentistry, Kwame Nkrumah University of Science and Technology. Statistically significant positive correlation was observed between left hand length and right hand length (R = 0.923, p = 0.000). From the binary regression model, it could be speculated that left-hand breadth could predict female populations native to the savanna zone (LHB: β = -2.37, Expβ = 0.09, p = 0.014). However, right-hand breadth and length and left hand length did not show any potential of prediction (RHB: β = 0.900, Expβ = 2.460, p = 0.410; RHL: β = 0.168, Expβ = 1.683, p = 0.803; LHL: β = -0.300, Expβ = 0.741, p = 0.656). The study therefore may speculate that left handbreadth could have the potential to differentiate female populations native to savanna zone from females native to forest zone in Ghana.

Prediction of Body Height Using Hand Length and Hand Breadth in Pharmacy and Nursing Students at Misrake Ghion College, Northeast Ethiopia: An Anthropometry Study.

To predict body height using hand length and hand breadth in pharmacy and nursing students at Misrake Ghion College, Northeast Ethiopia. A cross-sectional prospective study was conducted from October 15 to January 20, 2021. The study was carried out on 316 students (160 males and 156 females). The study participants were from the Amhara ethnic groups, with the age range of 18 to 25 years. Body height, hand length, and hand breath were measured and analyzed using SPSS version 23. The strength of association was evaluated using correlation analysis. The significance level was set at p < 0.05. A paired sample t test was performed. Regression equations were derived using simple and multiple linear regression analysis. Hand length and hand breadth had a positive significant correlation with body height in both male and females. In both males and females, left hand length had a strong significant correlation (males r = 0.768, females r = 0.670), followed by right hand length (males r = 0.711, females r = 0.626). Regarding hand length, right hand breadth (males r = 0.671, female r = 0.438) and left hand length (males r = 0.504, females r = 0.525). There was a significant bilateral difference in hand length and hand breadth on its right and left sides (p < 0.05). Simple and multiple regression equations were formulated for each sex. In both males and females, body height can be estimated from hand length and breadth using simple or multiple regression equations.

Association between anthropometric, physical and demographic characteristics and performance among NCAA Division III swimmers.

Anthropometric, physical and demographic characteristics have the potential to affect performance in competitive pool swimmers. Study aimed were therefore to examine the effect of 26 anthropometric, physical and demographic characteristics on qualification for Nationals and swim times among both male and female collegiate swimmers in separate analyses. Swim times were determined by swimmers' best swim time for their best swim stroke as a percent of the top swim time among Division III collegiate swimmers during the 2017-2018 swim season. Lower body fat measured mid-season and a greater ratio of height to arm span were associated with qualifying for Nationals among females. For males, associations were present for older age, shorter left-hand length and larger left arm circumference; and qualifying for Nationals. In relation to percent of top swim times, there was an association between larger right-hand width and left foot length among males. None of the other associations achieved statistical significance. Owing to the large number of analyses performed and the resultant likelihood of type I errors as well as the small effect sizes in most statistically significant associations, study results suggest that collegiate swimmers should not be chosen for swim teams based on any of the non-modifiable anthropometric or physical characteristics that were measured in this study. Results suggest however, that swim speed times are decreased among female collegiate swimmers with lower body fat percent when measured mid-season.

Correlation Between Hand Length And Stature

Objective: The main objective is to know the correlation between hand length and height so that a regression equation could be obtained to use for personal identification. Method: A correlational study conducted at Sialkot medical college between April, 2022 to June, 2022. Only female students of Sialkot medical college were selected by non-probability purposive sampling technique. Sample size was 141. Those having any deformity of vertebral column and hand deformity were not selected. After taking informed consent measurements were taken. Stadiometer was used to measure the height and vernier caliber was used to measure hand length. The measurements were taken in inches. Descriptive data was calculated by using SPSS 25. Correlation was found and regression equation was obtained. Regression curve was also obtained. Graphs and table were formed. Results: Value of pearson coefficient between right hand length and height was 0.780 and between left hand length and height was 0.752. Conclusion: Hand length can be used to estimate height of the person helping to short list the persons to be identified.

Forensic tool for sex prediction- hand dimensions.

Determination of sex from mutilated body fragments can perform vital role for identification of departed soul. Forensic authority pacts with human identification from the hand measurements which is of prodigious assessment during tragedies, terror attacks and in criminality. Present study explored the analytical role of the anthropometric measurements of hand dimensions, find demarking points for male and female, check percentage exactitude of sex determination in Western Indian population. The study was piloted on a sample of 504 individuals. All the measurements were taken by standard procedure. Discriminant analysis and demarking points were created for all hand measurements. Males have a significantly higher values of all measurements than females. The left-hand length measurement unveiled a noteworthy sexual dimorphism index (110.80). The higher value of the demarking point labelled as males. The best sexually dimorphic hand dimensions showed the utmost precision left hand length (95% in the male), followed by right hand length (76.1%). All hand measurements like length, breadth and index are displaying sexual dimorphism, hence they can be used for determination of sex when isolated hand is found.

The Influence of Parents’ Education on Growth Pattern of Children Aged 5-12 Years From Kazaure Emirate, Jigawa State, Nigeria

Anthropometry is defined as the measurements of different parts of the body and is widely used in surveys as an indicator of nutritional and health status. Studies revealed that large number of socio-economic variables are associated with the physical development of children. These variables consist of parental profession, income, education, birth order, family size, and urbanization. Materials used for the study were Stadiometer, non-elastic measuring tape, Skin fold caliper. The study involved a cross-sectional survey comprising of 863 pupils randomly selected from public primary schools in Kazaure emirate. The subjects were noted for sex and age. A stadiometer was used to measure height to the nearest 0.1 cm and weight to the nearest 0.5 kg. A non-elastic measuring tape was used for the measurement of head, neck, chest, mid upper arm, hip, waist and calf circumferences to the nearest 0.1cm respectively. A Harpenden skin fold caliper was used for the measurement of biceps and triceps skin fold thicknesses to the nearest 0.1 mm respectively. The study participants were apparently healthy public primary school pupils aged between 5 - 12years, from Kazaure Emirate and ofHausa ethnic group (parents and grandparents are Hausa). Based on lack of parents’ formal education, males had higher values of neck circumference (NC) and chest circumference (CTC) than females with statistical difference at p&lt;0.05. However,females had higher values ofcephalic index (CI) than males with statistical difference at p&lt;0.05.Based on the level of education of parents (primary, secondary and tertiary education), males had higher values of height (HT), weight (WT), BMI, head circumference (HDC), NC, CTC, waist circumference (WC) and calf circumference (CC) than females with statistical difference at p&lt;0.05. However, females showed higher mean values of triceps skinfold thickness (TSF) and hip circumference (HC) than males with statistical difference at p&lt;0.05. Males had higher values ofhead length (HDL), head breadth (HDB), facial length (FL) and facial breadth (FB) than females with statistical difference at p&lt;0.05. Conversely, females showed higher mean value ofcephalic index (CI) than males with statistical difference at p&lt;0.05.Males had higher values of right humerus length (RHML), left humerus length LHML), right ulna length (RUL), left ulna length (LUL), right radial length (RRL), left radial length (LRL), right hand length (RHNL), left hand length (LHNL), right hand breadth (RHNB) and left hand breadth (LHNB) than females with statistical difference at p&lt;0.05. Males had higher values of right tibial length (RTBL), left tibial length (LTBL), right fibula length (RFBL), left fibula length (LFBL), right foot length (RFTL), left foot length (LFTL), right foot breadth (RFTB) and left foot breadth (LFTB) than females with statistical difference at p&lt;0.05.

Sex estimation using discriminant analysis of hand dimensions among adult population in Ghana

The identification of a person forms a significant aspect of forensic investigations. Hand index derived from hand dimensions plays an important role in determining sex, age and population affinity in forensic and legal sciences. Sex estimation from anonymous body parts has been very important in forensic and legal sciences. Sexual dimorphism has been reported using various body parts including hand dimensions in several countries, but no study using hand dimensions has been conducted among Ghanaians. This study, therefore, is aimed at using discriminant analysis in the estimation of sex from hand dimensions. A sample size of 150 participants was recruited into the study. They were made of 79 females and 71 males aged between 18 and 90 years (as maximum growth of hand is attained from age 18 years onwards). The lengths and breadths of both hands of each participant were measured. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 20 for Windows. The mean right-hand length was 17.42 ± 01. cm (females) and 19.1 ± 1.38 cm (males) while the left-hand length was 17.7 ± 1.18 cm (females) and 19.0 ± 1.38 cm (males). The predominant palmar type was the mesocheri and demonstrated high accuracy for the estimation of sex. The accuracy of sex estimation using the formula derived was 74.0 %. This serves as a preliminary study and further study in larger sample size would be helpful in sex discrimination among Ghanaians.

Estimation of stature from anthropometric measurements of hands in living population of central India

Estimation of stature from dismembered body parts, as seen in cases of explosion or high impact vehicular trauma, is a challenge for forensic pathologist. There is need for population specific data for correct estimation of stature from dismembered limbs, as morphological traits of populations differ in different geographic regions. Present study was aimed at finding the correlation of stature with dimension of hands and estimating the stature by deriving regression equation in living population of central India region. Study included 300 young healthy adults (male=150, female=150). Standing height and dimension of right and left hands were measured in millimeter. Among males the highest correlation was exhibited by right hand length (r=0.592) and the lowest by left hand breadth (r=0.068) and among females highest correlation was exhibited by left hand length(r=0.524) and lowest by the right hand breadth (r=0.052). It is concluded that dimensions of hands can provide good reliability in estimating the stature, in the central India region population.

Estimation of stature based on hand length among students of Uttar Pradesh

Stature is one of the most useful anthropometric parameters which can be used to determine the identity of an individual. Stature and measurements of various body parts have become useful in forensic medicine and medico-legal cases to identify bodies that may have been destroyed in mass disasters like plane crashes, blasts and accidents etc.The aim of this study was to determine anthropometric values for stature and hand length in Uttar Pradesh population and to estimate height from hand length with the help of a regression equation formula. The present study was conducted on a sample of 400 students of Integral University (200 males and 200 females). Hand length (right and left) was measured and height was also recorded.In this study a significant and positive correlation was found between stature, right and left-hand length in males and females. In the present study, we concluded that the mean stature of males was higher than females and using regression equation accurate stature can be calculated from hand length.

Comparison of Upper Extremities of Children Who Playing and Not Playing Basketball

In this study, it is aimed to compare the upper extremities of children who play and do not play basketball. In this study, measurements were taken in the upper extremities of a total of 200 secondary school students playing basketball and non-playing, with a mean age range of 11 ± 1.08 (did play sports) - 11 ± 0.8 (did not play sports). The average height and weight ratio of the students who did and did not play sports were 153.5 ± 12.9 - 149.2 ± 8.1 cm and 46.7 ± 12.04 - 43.08 ± 12.9 kg respectively. In the right and left upper extremities of the students who play sports, arm length was 28.4 ± 3.1 - 28.4 ± 3.01, the forearm length was 24.1 ± 2.4 - 24.1 ± 2.4, hand length was 15.9 ± 1.8 to 15.9 ± 1.6, arm circumference was 23.2 ± 3.9 - 23.0 ± 3.8, the circumference of forearm was 20.8 ± 2.5 - 20.6 ± 2.5, hand width was 7.8 ± 0.8 to 7.9 ± 0.8. The results of the biacromial width and bideltoid width measurements were 25.5 ± 3.13 and 39.2 ± 4.7, respectively. In the right and left upper extremities of students who did not do sports, arm length was 26.8 ± 2.5 - 26.6 ± 2.4, forearm length was 23.3 ± 2.1 - 23.3 ± 2.0, hand length was 16.0 ± 1.5 - 16.2 ± 1.5, arm circumference was 22.4 ± 3.5 to 22.4 ± 3.5, circumference of forearm was19.4 ± 2.5 - 19.4 ± 2.5, hand width was 7.6 ± 0.9 - 7.7 ± 0.9. The results of the biacromial and bideltoid width measurements were 28.8 ± 3.8 and 37.6 ± 4.4, respectively. As a result of the evaluation made, there was a difference between arm circumference measurements (p = 0.02) when the measurements taken from the right and left extremities of the students who did sports and did not do sports were compared. It was observed that the difference between right - left arm length (p = 0.001) and right - left hand length (p = 0.02) was significant in the students who did not do sports. Playing basketball increases the arm circumference and forearm circumference in children.

Determination of Stature from Hand Length in Adults: A Regional Study in Chennai

Introduction: Estimation of stature from dismembered body parts assumes great significance and interest in the field of forensic medicine. Stature can be determined using the measurements of different body parts. Hand anthropometry is found to yield good predictive information about an individual’s stature. The aim of the present study was to formulate regression equations from hand length for stature estimation of both sexes in Chennai region. Materials and methods: In this cross sectional study, 619 subjects of both sexes with age ranging from 18 to 59 years of Chennai region were studied for stature and its relevance with that of hand length. Simple regression equations were derived by using two parameters – right hand length (RHL) and left hand length (LHL) - for estimation of stature of an individual for either sex separately. Findings: In the present study we found a significant (p<0.01) positive correlation between stature and hand length in both sexes. Stature estimation was relatively more accurate in males compared to females. Conclusion: The present study gives statistically significant positive correlation between stature and hand length. Stature can be successfully and accurately determined in this regional population by applying these regression equations.

Investigation of the Relationship Between Basic Swimming Instruction and Some Physical and Motor Characteristics

In this study, it was aimed to investigate whether basic swimming training has effects on height, body weight, right and left hand grip strength, right and left hand lengths, shoulder width, chest circumference, standing long jump characteristics. The study is important in terms of making individuals in the growth period and investigating the physical development of major technical studies from force studies. It is known that regular sport has also developed physical features along with many other features. However, there is not a complete consensus about the sport, its violence, its frequency and duration. The study using the experimental research method included 114 individuals with a mean age of 11.03 ± 1.23 years. The study group, consisting of 58 subjects, received regular swimming lessons twice a week for two hours at a time over a period of 7 months. The sedentary control group included 56 subjects who received no sports instruction apart from their standard physical education classes. Prior to the start of the study, measurements were taken for height, body mass, right and left hand grip strength, right and left hand length, shoulder width, chest circumference, and standing long jump for both groups. The same measurements were taken again 7 months later, at the conclusion of the study. The differences between the initial and final measurements of both the study group and the control group were statistically compared within the group and between the groups. In this comparison, the General Linear Model method was used in the SPSS 21 Package program. As a result, it was found that the increase in height, body weight, right hand grip strength, right and left hand lengths, chest circumference and standing long jump mean values of swimming training subjects were found to be different at p &lt;0.001 in the control group in seven months period. It was also found that the increase in the mean value of left hand grip strength in both groups was significantly different in favor of swimming training subjects (p &lt;0.005). The increase in shoulder width mean values of the study group and the control group did not differ between the groups (p&gt; 0,005).

Estimation of stature from hand length and hand breadth in medical students of Maharashtra, India

Background: For identification, stature can be estimated from body parameters using regression equation or multiplication factor. However, regression equations and multiplication factors are specific for the region only and same formulae cannot be used in all population. Aim: To formulate regression equation and multiplication factor for estimation of stature from hand length (HL) and hand breadth (HB) for a region in Maharashtra, India. Materials and Methods: It was a cross-sectional study and 400 students of three Government Medical Colleges of Maharashtra, aged 18-24 years were enrolled for the study during 2011-2013. Stature, HL, and HB were measured and subjected to statistical analysis. Unpaired t-test and simple linear regression were used. Results: Stature, HL, and HB of 400 medical students (219 males and 181 females) were measured. Subjects were divided into six groups depending upon age. Simple regression equation and multiplication factor for male and female, and for each age group were derived for estimation of stature. We found correlation coefficient (R) of 0.74 for right HL (RHL), 0.75 for left HL (LHL), 0.45 for right HB and 0.46 for left HB in male, and 0.75 for RHL, 0.74 for LHL, 0.56 for right HB and 0.55 for left HB in female by using simple regression, which showed strong correlation between stature and HL, and HB. Conclusion: Stature can be accurately estimated from HL and HB by using simple regression equation or multiplication factor.

Age estimation in subadults based on general anthropometric parameters in a population of Romania

In Romania the cases of anthropological forensic exams performed in order to estimate the age of subadults include mostly people with an extremely low socioeconomic status, frequently homeless people, whose parents did not have a certified copy of the medical birth certificate issued. Given that the population for which these exams are done is relatively homogeneous in terms of socio-economic and ethnic factors, the purpose of this paper is to identify the utility of the isolated anthropometric exam in order to establish age. The study was conducted on a total of 181 forensic cases which required an anthropological forensic exam so as to estimate the age in subadult individuals (under 13 years old). The cases were selected from among those where one knew the exact age with a reasonable degree of certainty. The variables included in the study were: sex, weight, head circumference, teeth, maximum arm span, arm length, forearm length, left hand length, chest circumference, thigh length, calf length. For each parameter, a linear regression equation for males and respectively females was created. The adjusted R 2 values for the equations created based on the above parameters were in all cases over 0.5; the highest values were obtained, in the case of both sexes, for the waist and the maximum arm span. Conclusions: Based on the regression equations obtained for age estimation based on general anthropometric parameters one can create, either in Excel or in programming languages, algorithms that may, in many cases, allow the age identification with a few weeks as a margin of error. The best results in terms of age estimation were obtained using a combined method. However, even using a small number of markers one can reach a reasonable age estimation (+/-6 months), which is sufficient to correlate the anthropological data with those of the medical birth certificate. he subadults' age estimation is usually based on the analysis of the growth and development processes, while in adults it is based on skeletal and dental degeneration processes. The growth and development processes are much more homogeneous within the population, which makes them have a higher degree of certainty than those based on osteo-dental degeneration processes, which have been proved to have the tendency to overestimate young people's age and

Analysis of Selected Hand Anthropometric Measurements among South West Zone Inter University Male Handball Players

The purpose of this study was to analyse the selected hand anthropometric measurements among south zone inter university male handball players. The selected players right and left hand length and width were measured on 144 male handball players who had right hand as dominant hand. These players took part in south west zone inter university handball tournament for the year 2010-2011 organized by S.R.T.M University, Nanded, Maharashtra. In this study date was collected from teams who reached quarter finals and Annamalai University team. The hand length and width was selected as criterion variable and measured by vernier caliper, gulick tape and measuring scale. The collected data was analysed using ANOVA, when F is found to be significant Tukey HSD post hoc test was applied. The result of the study showed that right hand length (F = 1.61, p = 0.126) and left hand length (F = 1.19, p = 0.308) show no significant difference between the groups. However, right hand width (F = 5.450, p = 0.000) and left hand width (F = 6.302, p = 0.000). It shows that Rajasthan university handball players showed greater hand width on both hands than other team players. It can be concluded that hand width shows significant variations among the south west zone inter university handball tournament. The criterion variables which are selected in the present study show significant impact on griping the ball.

Prediction of stature using hand dimensions

In this study, an attempt was made to find out possible correlations between hand dimensions and stature using linear and curvilinear regression models for both genders. The study was conducted amongst 250 medical students (125 male and 125 female) aged 18–30 years. Each student has been studied for measurements of stature, hand length and hand breadth. To explain stature, all the explanatory variables like age, sex, hand length (right and left) and hand breadth (right and left) were included for model generation using SPSS. A general linear regression model was found to be best explanatory in both males and females, however, amongst the curvilinear models; the exponential model emerged as the ‘best’ in explaining stature of the individual. Left hand length alone explained very significantly ( P < 0.001).

Prediction of Stature From Hand Length and Breadth – An Anthropometric Study on Christian Garo tribal Bangladeshi females

Context: Body physique is influenced to a greater extent by climatic, hereditary, nutritional and racial factors. Since in Bangladesh variegated ethnic groups inhabit in different conditions, no single anthropometric formula is suitable. The stature prediction occupies relatively a central position in the anthropometric research. And estimation of stature of an individual from the mutilated or amputated limbs has obvious significance in the personal identification in the events of murders, accidents or natural disasters. The present study was undertaken to measure the stature, as well as some length and breadth of hand and to determine whether there is any correlation between the stature and the hand variables. And to estimate using respective multiplication factors the stature from these variables and to assess the effectiveness of the above estimations by comparing the ‘estimated' values with the ‘measured' values. Methods: The study was carried out with a total number of 100 Christian Garo adult females aged between 25 to 45 years. Hand length and breadth along with their stature were measured directly from the subjects by using anthropometric sliding, spreading calipers and measuring tape. The data were then statistically analyzed by computation to find out its normative value. Multiplication factors were estimated for estimating stature and comparison were made between measured and estimated stature using paired "t" test. Result: The mean normal values of the hand measurements (right and left hand length were 16.39 ± 0.72 cm and 16.33 ± 0.67 cm respectively and breadth of right and left hand were 7.22 ± 0.38 cm and 7.18 ± 0.3 cm respectively) and the stature (152.79 ± 5.62 cm) were found. The multiplication factors were estimated for the same hand measurements with the stature. Significant positive correlation was found in case of hand length with the stature. There was positive correlation (r=0.17, p=0.09 and r=0.15, p=0.12) between the stature and breadth of the right and left hand (Figure 3.21) but the result did not reach any statistically significant level.
