INTRODUCTION: The objective of the study was to find the relationship between handgrip endurance and handwriting legibility among school going children between age 9-16 years. METHOD: 100 students between age group of 9-16 years were selected from various schools in and around Pune for the study using convenient sampling method. An assent form was obtained from parent of each participant and a thorough explanation about the procedure was provided to them. Static and dynamic handgrip endurance tests were carried out using the dynamometer. Handwriting samples were obtained and handwriting legibility was assessed using the handwriting legibility scale. RESULT: The co-relation coefficient (r) between Static Handgrip Endurance and Handwriting Legibility Score was-0.25 which signifies negative co-relation between them. This means as static handgrip endurance increases the HLS score decreases, i.e, more the endurance better is the handwriting. The co-relation coefficient (r) between Dynamic Handgrip Endurance and Handwriting Legibility Score was 0.68 which signifies negative co-relation between them. This means as dynamic handgrip endurance increases the HLS score decreases, i.e. more the endurance better is the handwriting. CONCLUSION: This study provides evidence that there is significant negative correlation between handgrip endurance and handwriting legibility score among school going children between age group of 9-16 years. We conclude that if static or dynamic handgrip endurance is less than the handwriting is poor and higher handgrip endurance denotes good handwriting.

Handwriting is an important functional task that needs to be performed by children in lower grades of elementary school, and it is an essential ability for academic achievements. To evaluate the ability of handwriting performance in children, various dimensions must be considered including the domain of handwriting, legibility, speed, and ergonomic factors. During the process of handwriting, most of the movements come from the forearm while the shoulder provides the power with minimum movement occurring at fingers and wrist. Muscular endurance is the ability of a muscle or muscle group to do repeated contractions against a less-than-maximum resistance for a given period. Fatigue of the Proximal muscles has been reportedly affected the coordination of Distal muscles. This study studies the correlation between scapular muscle endurance and handwriting legibility in school children. Method: In this study, 70 samples were collected according to the inclusion and exclusion criteria. The test was explained to them and their parents in detail and ascent. Handwriting legibility was assessed using a handwriting legibility scale. Scapular muscle endurance was assessed using the Scapular muscle endurance test. Data was collected and analyzed. Results: The results showed that there was a significant positive correlation between scapular muscle endurance and handwriting legibility. The statistical analysis showed that the correlation coefficient (r=0.5) which states that there is a moderately positive correlation. The p-value was <0.0001 which is considered extremely significant. Conclusion: This study concludes that there is a positive correlation between scapular muscle endurance and handwriting legibility.

Long Term Consistency of Handwriting Grip Kinetics in Adults
Journal of Biomechanical Engineering, 2014
While there is growing interest in clinical applications of handwriting grip kinetics, the consistency of these forces over time is not well-understood at present. In this study, we investigated the short- and long-term intra-participant consistency and inter-participant differences in grip kinetics associated with adult signature writing. Grip data were collected from 20 adult participants using a digitizing tablet and an instrumented pen. The first phase of data collection occurred over 10 separate days within a three week period. To ascertain long-term consistency, a second phase of data collection followed, one day per month over several months. In both phases, data were collected three times a day. After pre-processing and feature extraction, nonparametric statistical tests were used to compare the within-participant grip force variation between the two phases. Participant classification based on grip force features was used to determine the relative magnitude of inter-particip...
Hand Grip Strength in Students: Differences in the Gender Dimorphism
International Journal of Physical Education, Fitness and Sports, 2021
The hands are anatomically specialized for manipulative tasks with different physical objects, where they can cope with certain loads with different forces and intensity. During various physical and sports activities, the hands produce the appropriate muscular force for gripping, which manifests as the hand grip's force. For this reason, hand grip strength (HGS) is recognized as a limiting factor in all manipulative activities performed by the cranial part of the body. The current research included a sample of 22 subjects, 16 male Body Height (BH=180.28±4.65cm); Body Weight (BW=80.05±9.96kg), Body Mass Index (BMI=24.61±2.74kg/m²) and 6 female subjects Body Height (BH=167.42±11.11cm); Body Weight (BW=64.80±10.09kg); Body Mass Index (BMI=23.02±1.57kg/m²) on the third year of study at the Faculty of Physical Education and Sports. This study aimed to determine the maximum isometric muscle force of the handgrip and differences between the same gender of students. A t-test for small samples was applied for data processing, and the relevant statistical parameters were calculated. The obtained t-test results confirmed statistically significant differences between the so-called dominant and non-dominant hands in male subjects (t=4.158; p<0.05) and female subjects (t=3.176; p<0.05). The obtained results of this research will be used for analytical and diagnostic purposes with a wide range of activities in the population of physical education and sports students (assessment of physical ability, trends, and tendencies to monitor and change abilities, influence on the implementation of certain curricula of some subjects studied at the faculty, etc.).
Grip Force Variability and Its Effects on Children’s Handwriting Legibility, Form, and Strokes
Journal of Biomechanical Engineering, 2010
A comprehensive understanding of the underlying biomechanical processes during handwriting is needed to accurately guide clinical interventions. To date, quantitative measurement of such biomechanical processes has largely excluded measurements of the forces exerted radially on the barrel of the writing utensil (grip forces) and how they vary over time during a handwriting task. An instrumented writing utensil was deployed for a direct measurement of kinematic and temporal information during a writing task, as well as forces exerted on the writing surface and on the barrel of the pen. The writing utensil was used by a cohort of 35 students (19 males), 16 in first grade and 19 in second grade, as they performed the Minnesota Handwriting Assessment (MHA) test. Quantitative grip force variability measures were computed and tested as correlates of handwriting legibility, form, and strokes. Grip force variability was shown to correlate strongly with handwriting quality, in particular for students classified by the MHA as nonproficient writers. More specifically, static grip force patterns were shown to result in poor handwriting quality and in greater variation in handwriting stroke durations. Grip force variability throughout the writing task was shown to be significantly lower for nonproficient writers (t-test, p Ͻ 0.01) while the number of strokes and per-stroke durations were shown to be higher ͑p Ͻ 0.03͒. The results suggest that grip force dynamics play a key role in determining handwriting quality and stroke characteris-tics. In particular, students with writing difficulties exhibited more static grip force patterns, lower legibility and form scores, as well as increased variation in stroke durations. These findings shed light on the underlying processes of handwriting and grip force modulation and may help to improve intervention planning.

Background: Handgrip strength (HGS) not only reflects the strength of the upper limb muscles; it also reflects the overall strength of the skeletal muscles and physical fitness. Further, it is being used as an indicator of nutritional status too. Undergraduate students have been described as having low physical fitness due to their sedentary lifestyle in many studies. Therefore, this study describes the HGS and its association with gender, hand dominance, Body Mass Index (BMI), hand and forearm anthropometries in a group of young undergraduate students of the University who do not participate in regular physical training. Methods: This is a cross-sectional descriptive study, and was conducted among healthy first-year residential undergraduate student population (n= 524, 350 females, 174 males, mean age= 21.31 ± 0.93). Main outcome measures were HGS, gender, hand dominance, BMI, hand length, hand span, handbreadth, forearm length, forearm girth, and wrist circumference. Results: HGS of the dominant hand of male students was 35.27 ± 5.91 kg, which is significantly higher (p< 0.05) than that of the females (19.52 ± 4.34 kg). However, it has a significant but weakly positive correlation with other variables measured except for forearm length. Conclusion: This study has provided an insight into the association of low HGS with physical inactivity in an academically oriented group where the BMI is within the normal range and the association of higher HGS with hand dominance and male gender.

Background: Muscular strength of the adult population is the key factor for their potency. Dominant hand plays an important role in most of the daily muscular activities and sport activities. There are many factors which may affect the handgrip strength and very few studies especially in India have shown their correlation with handgrip strength.Aims and Objectives: The cross-sectional study was carried out to find the correlation of age, body height, body weight, body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and hand span of dominant hand with dominant handgrip strength in adult males and females. Material and Methods: The study included 121 healthy adults, 76 males and 45 females. All the parameters to be studied were measured using the standard methods and dominant handgrip strength was measured using the standard adjustable digital hand grip dynamometer in both males and females.Statistical Analysis: The data was analysed by Pearson’s correlation coefficients and 5% level of probability was used to indicate the statistical significance. Results: The dominant hand’s grip strength in males (M) and females (F) have significant positive correlation (P < 0.05 –0.001) with body height (r = 0.245 (M), 0.379 (F)), body weight (r = 0.497 (M), 0.484 (F)), BMI (r = 0.428 (M), 0.350 (F)) and hand span of dominant hand (r = 0.761 (M), 0.418 (F)). Whereas handgrip strength in subjects have non-significant weak positive correlation ship (P > 0.05) with WC (r = 0.180 (M), 0.102 (F)) and WHR (r = 0.058 (M), 0.101 (F)). Conclusion: Our study showed the significant positive correlation of dominant hand’s grip strength with age, body height, body weight, BMI and hand span of dominant hand. Weak positive but not significant, correlation of handgrip strength was also observed with WC and WHR. More research work is needed to obtain the precise correlation of these variables with handgrip strength of dominant hand.
