Abstract We aimed to use hand dexterity and grip strength test as objective measures to compare the difference in surgeon fatigue associated with robotic and laparoscopic colorectal surgery. We used the Purdue Pegboard Test to assess hand dexterity and the Camry Electronic Handgrip Dynamometer to assess hand grip strength. Eighteen patients were operated on, including 10 robotic and 8 laparoscopic cases. Statistical analysis revealed no difference in dexterity or muscle fatigue after operating with the robot. In contrast, there was a significant difference in the hand grip strength of both hands after laparoscopic surgery. Our results show that the resultant fatigue after laparoscopy affects both hands of the surgeon. In contrast, there was no difference in dexterity or muscle fatigue after operating with the robot. Given the demands of complex colorectal surgeries, robotics may be a means of optimizing surgeon performance by reducing fatigue.

Abstract Background: Minimally-invasive surgery has been shown to more demanding on the surgeon than open surgery. This can be manifested as physical fatigue and impaired dexterity, affecting the performance of the surgeon. In this study, we aimed to use hand dexterity and grip strength test as objective measures to compare the difference in surgeon fatigue associated with robotic and laparoscopic colorectal surgery. Methods: A pilot study was conducted between February 2019 and May 2019, recruiting consecutive colorectal patients operated on by a single surgeon using laparoscopy or robotics. We used the Purdue Pegboard Test (PBT) to assess hand dexterity, and the Camry Electronic Handgrip Dynamometer to assess hand grip strength. Before each operative procedure, the surgeon was tasked to perform both tests in a standardized sequence. These tests were repeated two hours into surgery.Results: Eighteen patients were operated on, including 10 robotic and 8 laparoscopic cases. Statistical analysis revealed no difference in dexterity or muscle fatigue after operating with the robot. In contrast, there was a significant difference in the hand grip strength of both hands after laparoscopic surgery (P = 0.04 and 0.02, respectively).Conclusions: Our results show that the resultant fatigue after laparoscopy affects both hands of the surgeon. In contrast, there was no difference in dexterity or muscle fatigue after operating with the robot. Given the demands of complex colorectal surgeries, robotics may be a means of optimizing surgeon performance by reducing fatigue.

Background: Pain of the hand distal interphalangeal joints may result from trauma, osteoarthritis or inflammatory arthritis. When symptoms are not controlled by non-operative means, surgical arthrodesis may be performed, resulting in complete stiffness of the joint and possible weakening of grip strength. This study aims to quantify the effect of a stiff ring finger distal interphalangeal joint on overall grip strength. Methods: One hundred participants were screened to exclude upper limb pathology. A Jamar dynamometer was used to assess overall hand grip strength. A splint was used to prevent distal interphalangeal joint flexion, thus replicating a fused distal interphalangeal joint. Participants were tested with and without the splint and the results compared. The mean of three grip strength tests was taken. Results: The participants included 55 females. Mean age was 31 (18–60 years). 76 participants had a reduction in grip strength with splinting, with a significant difference seen (p < 0.05) on Wilcoxon signed rank test. The median reduction in grip strength with splinting was 1.67 kg. However only 10 participants (10%) had a grip strength loss of greater than 6.5 kg, which is the minimal clinically important difference. Conclusions: This study found a significant loss in overall hand grip strength when the ring finger distal interphalangeal joint was stiffened. However, despite this significant change, only 10 (10%) participants experienced a reduction of greater than 6.5 kg. This is the level of weakness felt to be required to reduce function. Thus our results suggest that 90% of patients with a stiff ring finger distal interphalangeal joint are unlikely to have a clinically identifiable functional reduction in grip strength as a result.

Introduction: Nutritional content of diet of vegetarian and non-vegetarian differs in terms of food composition and vegetarian diets are often low in protein, probably causing a difference in body composition, structure and strength characteristics. Purpose of study: To study anthropometric, body composition and hand strength differences among 641 vegetarian and 424 non-vegetarian Indian women, aged 20–60 yrs. Methods: ANOVA, t-test, multivariable stepwise regression and logistic regressions were performed to analyse association between BMI, hand grip strength and potential confounders using SPSS Version 17 for Windows. p < 0.05 referred to as statistically significant. Results: Vegetarians had less body fat than non-vegetarians. Statistically significant difference was found in their grip strength (GS) (t = 2.459, p < 0.05) and BMI (t = 2.188, p < 0.05). Height and weight were positively associated with grip strength in the vegetarian group while height and fat free mass were seen to be positively associated with grip strength in the non-vegetarian group. Grip strength was greater in non-vegetarian group and the vegetarians had lower BMI (25.33 kg/mt2 ± 4.56) than nonvegetarians (25.95 kg/mt2 ± 4.45, t-test = 2.188, p<0.05). Conclusion: Those with greater grip strength (non-vegetarian group) had greater chance of being obese than those with lower grip strength (vegetarian group). (OR = 2.609, 95% CI 1.487 - 4.577). However, lower levels of body mass indices of the vegetarian women suggest that they are healthier than non-vegetarians in terms of BMI.  DOI: http://dx.doi.org/10.3126/ajms.v4i3.8096   Asian Journal of Medical Sciences 4(2013) 43-51

Although recent clinical studies have suggested that water intake enhances muscle mass, its impact on muscle strength remain unclear, especially in older adults. This cross-sectional, population-based study using a representative sample of Koreans investigated the relationship of water intake with hand grip strength (HGS) in 4443 older adults, including 2090 men aged ≥50 years and 2253 postmenopausal women. A digital grip strength dynamometer was used for HGS assessment. Low muscle strength was defined by the Korean-specific HGS cut-off value and adequate water intake was defined according to the Korean dietary reference intakes. In an unadjusted model, water intake was significantly higher in men and women without than with low muscle strength (both p < 0.001), but this difference disappeared after adjustment for confounding variables in both men (p = 0.050) and women (p = 0.245). Similarly, the correlation between water intake and HGS, the difference in HGS depending on adequate water intake status, and the risk of low muscle strength depending on water intake quartile were significant only in the unadjusted model. These data indicate that factors such as age, body size, and resistance exercise contribute to improvements in HGS in older adults, whereas water intake may not.

Abstract The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student’s t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were nonmodifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations.

Objectives: Thumb metacarpophalangeal (MCP) joint injury is frequently seen due to dynamic character of handball game. Spica taping is generally applied to protect thumb during returning to sports activities following rehabilitation in handball player. The aim of this study was to investigate the effect of spica taping on grip strength and grip endurance in professional handball players. Methods: Thirteen female handball players who was playing in Turkey Handball Federation Super League participated in the study. Mean age was 25.23±5.47 years, mean age of beginning to sports was 13.15±5.62 years, mean body mass index was (BMI) 22.38±2.74 kg/cm2. Hand grip strength and grip endurance in dominant side were evaluated before and after spica taping. “Jamar Hand Dynamometer” was used to assess hand grip strength. Grip endurance was measured in seconds during half of average grip strength sustaining for each players. All assessments were applied while sitting during shoulder adduction and neutral rotation with 90° elbow flexion, forearm midrotation, and neutral wrist position. Measurements were repeated 3 times and average values were recorded. Results: There was a statistically significant difference in grip strength between before and after spica taping application (p<0.001). There was a statistically difference in grip endurance between before and after spica taping application (p<0.001). Conclusion: Our results demonstrated that thumb spica taping is effective in improving grip strength and grip endurance in handball players. We suggest that supporting thumb stabilization without limiting hand functions might protect the MCP joint, and contribute injury prevention accompanying with improving sports performance. Consequently, thumb taping is recommended to handball players before competition.

Background.Assessment of hand grip strength is vital for the evaluation of upper limb impairments and effective exercise prescription. Present study primarily aimed to investigate the effect of head-neck positions on the hand grip strength in healthy young adults. Secondarily, the present study compared hand grip strength between left versus right hand in different head-neck positions.Methods.Healthy young adults (age 19 – 30 year; n = 40) participated in this cross-sectional study. Hand grip strength was assessed in three head-neck positions (neutral, rotation left, and rotation right) using the standard adjustable Jamar hand dynamometer.Results. Hand grip strength in both sides (left and right) was greatest in the head-neck neutral position. Hand grip strength measured in head-neck left rotation position displayed the least strength in both sides. There was no significant difference noted between left and right side hand grip strength measured in head-neck neutral and right rotation positions. However, there was a significant difference noted between left and right side hand grip strength measured in head-neck left rotation positions. There was no significant effect of head-neck positions on hand grip strength noted in both sides.Conclusions. Hand grip strength was highest in the head-neck neutral position followed by head-neck rotation to the right. However, head-neck positions did not significantly affect hand grip strength in healthy young adults. Further studies assessing the hand grip strength in different neck positions in patients with neck pain and upper limb dysfunction may have significant implications for the assessment of hand grip strength.

Hand Grip Strength (HGS) is an indicator of muscle strength tha has been a predictor of physical capacity and long-term health. There has been a a decrease in HGS among youth and is related with several factors such us body mass index (BMI) and protein intake, but the available researches are still inconsistent. This cross sectional study examined the level of HGS and it’s relationship with BMI and protein intake among female college student of UHAMKA Jakarta. HGS were measured by Smedley Dynamometer and were carried out according to the Southampton Protocol. Anthropometric measurements and self 3-day food records were performed to obtain BMI and total protein intake. Chi square test was performed to reveal the difference proportion of low HGS among various groups. The results showed that the average HGS score was 21.70 ± 7.09 kg, of which 48.7% of respondents were classified as low HGS. There was no significant difference of low HGS proportion between normal BMI and abnormal BMI (less and more) (P value = 0.481). However, the proportion of low HGS was significantly higher among those who had deficit protein intake compared to normal (P value = 0,000). Therefore, an adequate protein intake is needed to maintain muscle strength among youth.   Keywords: Muscle strength, hand grip strength, BMI, protein intake, youth

It is believed that exposure to whole-body vibration (WBV) may increase seated occupant drowsiness and seated. The purpose of this paper is to investigate the strength of the hand grip among the young adults in Malaysia. Also, to examine the correlation between anthropometry factors such as hand length (HL), hand breadth (HB), wrist circumference (WC) and body mass index (BMI) with average full hand grip strength of young adults. 40 Malaysian young adults with equal females and males and the range age of 23 to 28 years old voluntarily basis participated in this study. Three experiments were conducted in sitting position according to American Standard Hand Therapist (ASHT) with 45º, 90o and 135o of hand flexion using dynamometer. The results show the significant different full hand grip strength between Malaysian young adult females and females, the difference full hand grip strength for different hand flexion angles in sitting position and difference correlations between anthropometry factors and full hand grip strength for both young adult males and females.
