“…Consistent with the findings of several previous studies, the results of this study showed that hand strength in both hands were significantly greater in males than in females [2,5,[7][8][9][10][11][12][13]19,24,26,[36][37][38]. Female hand strength was between 59.1% and 73% of male hand strength for both hands.…”

“…Among the strength of five hand movements measured in employees in the healthcare industry, the order ranked from strongest to weakest for the right hand was as follows: grip, lateral pinch, ball of thumb, palmar pinch, and thumb press. As mentioned in previous studies, grip strength uses the muscles of the forearm, so it exerts the strongest force of the five different types, and the lateral pinch force is greater than the palmar pinch force [5,6,26]. Fewer muscle groups are used to perform the thumb press than the ball of thumb press, and the force exerted is consequently smaller.…”

“…Hand strength is an important reference used in the medical diagnosis of hand disorders and injuries to evaluate and compare treatments or predict mortality [1][2][3][4][5][6][7][8][9][10][11][12][13]; it is also used in the assessment of the risk of musculoskeletal disorders (MSDs) for the improvement of task processes and design with regard to the manual handling of materials and other manual operations [14][15][16][17]. Therefore, the establishment of hand strength databases is an important issue in many countries.…”

Objectives: The purpose of this study is to establish the norms of hand grip strength in the healthcare industry in Taiwan and propose models to predict the strength of hand movement by regression with demographic and anthropometric factors. Methods: This is a cross-sectional study with a stratified convenience sample of workers in healthcare service industries in central Taiwan. Three hundred twenty-nine healthy subjects were recruited. Strength of different hand movement were tested three times in both hands and rests were given between tests. Results: Female strength of these hand movement was 59.1% to 73.0% that in males (p < 0.001). In general, the hand strength of male workers in the healthcare industry was less than that of male workers in the manufacturing industry (p < 0.001). In the prediction model, sex and weight played important roles in predicting hand strength. Conclusions: The norms of different types of hand strength was investigated the first time in workers in the healthcare industry in Taiwan. The tasks performed by healthcare personnel vary widely, and this variable should be considered in a future prediction model.

“…This study recruited basketball, volleyball, and badminton athletes as experimental participants. The dominant leg for each participant was defined as the limb that the participant would use to kick a soccer ball, and the dominant hand was defined as the hand used for writing [19,20]. This study was approved by the Ethics Committee, and all athletes provided informed consent prior to participation [21].…”

The Effect of Divided Attention with Bounce Drop Jump on Dynamic Postural Stability

AbstractThis study determined the effect of divided attention on controlling postural stability during a drop vertical jump task. In total, 30 participants were tested for drop vertical jumps from a 30-cm high platform and landing on a single leg with or without divided attention tasks. Three-dimensional marker trajectories and ground reaction forces were collected simultaneously. Vertical ground reaction force, loading rate, and dynamic postural stability index were analyzed with or without divided attention tasks. The paired sample t test indicated a significantly low knee flexion angle, high vertical ground reaction force, and increased loading rate in the divided attention task. Moreover, participants showed an increased vertical stability index and dynamic postural stability index in the divided attention task than in the nondivided attention task. Thus, results demonstrated that the divided attention task could affect posture control, leading to poor dynamic posture stability and possibly increasing lower extremity injury risk. The influence of the divided attention task on movement quality likely indicates that an athlete can no longer focus his attention on the bounce drop jump maneuver. Therefore, the bounce drop jump combined with dynamic postural stability index could be used in posture stability screening.

“…Researchers have found that the development of grip strength and pinch strength has certain rules and characteristics in terms of sex, age, and handedness (i.e., left vs. right handedness). 18 – 20 Several studies have shown that grip and pinch strength increases with age and that grip and pinch strength is always greater in boys than girls of the same age. 12 , 21 However, the present study showed that boys had greater grip strength and pinch strength than girls of the same age only in some age groups, especially in the younger age groups.…”

Objective To evaluate the development level of children’s physiological hand shape indicators and their relationship with grip/pinch strength. Methods Hand shape and grip/pinch strength in 1255 Chinese children aged 5 to 13 years were prospectively measured. Development curves of physiological hand shape indicators and grip/pinch strength were constructed. Results The physiological hand shape indicators (full length, middle finger length, width, and wrist thickness) and grip/pinch strength of boys and girls increased with age and showed statistically significant differences at different ages. In most age groups, hand shape indicators and grip/pinch strength were larger in boys than in girls of the same age. After puberty, the physiological hand shape indicators and grip/pinch strength increased more rapidly in girls than in boys of the same age, and the differences gradually decreased thereafter. Moreover, a significant difference in pinch strength between the right and left hands was observed in most age groups. Pearson correlation analysis showed that the physiological hand shape indicators were significantly positively correlated with grip/pinch strength, height, weight, and body mass index. Conclusions This study revealed the relationship between physiological hand shape indicators and grip/pinch strength and provided reference ranges of physiological hand shape indicators and grip/pinch strength for children.
