“…Contrary to the other studies [40,41], this study concluded that hand circumference had no significant impact on hand grip strength as well as no significant influence of forearm circumference and hand length on hand grip strength. This study disagreed with the Kong and Kim result [42] where they found that the larger the hand length, wrist circumference and palm length, the stronger total grip strength. Also, this study disagreed with the Alahmari et al study [16] where they concluded that age, BMI, forearm circumference, and hand length have an impact on Saudi people hand grip strength.…”

Abstract-Objectives:To determine whether, hand's temperature, wearing glove, body mass index (BMI), and hand anthropometry have an influence on the hand grip strength in healthy male students. Methods: This cross-sectional descriptive study on eighteen healthy male volunteers, the mean of age (Standard Deviation) is 29.78 (2.9) years. Their ages and anthropometric characteristics including BMI, hand length, hand width, hand depth, hand palm and wrist circumference were measured. The hand was exposed to different bath temperatures ( ) and hand grip strength was measured using a Jamar hydraulic hand dynamometer with and without wearing chemical protection gloves. The data were analyzed using Shapiro-Wilk parametric test, Pearson correlation coefficient, and ANOVA. Results: ANOVA results show a significant effect of wearing a glove on hand grip strength, but there is no significant effect of changing skin temperature on hand grip strength. With respect to anthropometry measurements, a Pearson correlation coefficient matrix demonstrated an only significant correlation between the hand grip and hand width, but the other factors haven't any correlation with hand grip strength. Conclusion: Only wearing glove has an influence on the hand grip strength. Hand width has a significant impact on hand grip strength, but the other factors have no significant impact on hand grip strength in this study.

“…In the present study, the second position was selected because of its similarity to K-Force Grip dimensions. Nevertheless, the effectiveness of the handle position should be, and actually is, related to the anthropometric parameters of the hand [32]. Therefore, since the dimensions of the handle were similar but not the same, force level differences are not an unexpected finding.…”

Comparative Study of Validity and Reliability of Two Handgrip Dynamometers: K-Force Grip and Jamar

et al. 2021

Background: Handheld dynamometers are used for diagnosis and rehabilitation at several pathologies. Grip force is essential for a person’s quality of life. Most dynamometers are not equipped with rehabilitation or training protocols, although the bibliography highlights this need. Objective: To compare the validity and reliability of Jamar and K-Force Grip dynamometers in patients with shoulder impingement syndrome and healthy people. Methods: Concurrent validity was assessed using known weights. Forty-four (44) patients and 69 healthy adults performed three maximum repetitions in random order with each hand, at each instrument. Reliability was evaluated using ICCs for each instrument separately, and between the two instruments. The differences between the two dynamometers were evaluated using repeated t-tests. Results: Concurrent validity of the two instruments did not reveal fix or proportional bias. Analyses for reliability yield high correlation coefficients for both groups with the lower one being between the two instruments r = 0.90, p < 0.05, (0.72–0.91) for the healthy group. T-tests showed that all participants had lower force values when using the K-Force Grip (p < 0.05). Conclusion: Both dynamometers were reliable in measuring hand grip strength for both groups. K-Force Grip was reliable and valid with respect to Jamar that was used as a benchmark. The different handle dimensions between the two dynamometers may be the reason for the different force values.

“…Existing literature on ergonomic surgical instrument design suggests precision tools need to be manufactured in multiple sizes to allow ergonomic use through the range of hand sizes [ 12 ]. Further, the limited research we identified on the gender effects of hand mechanics indicates significant differences in force generation between male and female hands [ 13 ]. Multiple fields of surgery, including adult reconstructive surgery and spine surgery within orthopedics, have begun to acknowledge the toll poor ergonomics and work-related injuries can take on surgeons’ careers and their overall health and well-being [ 14 - 19 ].…”

Introduction: Orthopedic instrumentation is generally made as one-size-fits-all. The purpose of this study was to evaluate the effects of hand size and sex on ease of use and injury rates from orthopedic tools and surgical instruments.Methods: An anonymous 21-item online survey was distributed to orthopedic trainees and attendings. Questions regarding demographics, physical symptoms and treatment, perceptions, and instrument-specific concerns were included. The analysis included statistics comparing responses based on sex, height, and glove size, with significance as p<0.05.Results: There were 204 respondents: 119 female and 84 male. Male and female respondents differed significantly in height (mean difference 5.4 in, p<0.001) and glove size (median size 6.5 size for females, size 8 for males, p<0.001). While 69.8% of respondents reported physical discomfort or symptoms they attributed to their operating instruments, female surgeons were significantly more likely to endorse symptoms (87.3% female vs. 45.2% male, p<0.001). Of those reporting symptoms, 47.7% had undergone treatment, with no significant difference by surgeon sex (p=0.073). Female surgeons were significantly more likely than their male counterparts to have negative attitudes toward orthopedic surgical instruments and to report specific surgical instruments as difficult or uncomfortable to use. Conclusion:Female orthopedic surgeons are more likely than their male counterparts to report physical symptoms attributed to orthopedic surgical instruments, to have negative attitudes toward instruments, and to identify a larger number of common instruments as difficult or uncomfortable to use. Further emphasis on ergonomic instrument design is needed to allow all orthopedic surgeons to operate as safely and effectively as possible.
