Hand Grip

With increasing number of women entering into jobs traditionally held by men, it has been found that tools and equipment originally deisgned for the “average man” do not fit women, smaller mean or other persons. Thirty college students (7 females, 8 dominant left handed males and 8 dominant right handed males) squeezed alternately with both dominant and non-dominant hands twice a Lafayette dynamometer at 5 grip span settings. The results indicated that grip strength increased with increasing grip span up to the preferred grip span. Female grip strength was 53% of male grip strength. The non-dominant hand produced 89.6% of dominant hand grip strength. More interestingly both male and female left handers exihibited nearly identical grip strengths for both hands, leading one to suspect that left handed people are being forced to adapt to a right handed world. It thus appears that certain female workers may be at a double disadvantage with gender and left handedness reducing grip strength by 2/3. However, tools and equipment can be modified to accommodate weaker individuals.

The Relationship

Lateralization, which is also known as hand preference, and 2D:4D finger ratio is a sign of prenatal testosterone and known to be associated with strength. The aim of this study is to investigate the relationship between 2D: 4D, lateralization and hand grip strength in relation to hand and forearm that are thought to be effective in handball in elite handball players. 67 female and 67 male elite players participated in this study. The height, weight, body-mass index and hand preference of these athletes have been identified and 2D: 4D finger measurements and hand grip strength tests were performed. When identifying the preferences regarding lateralization, the hand distribution preference was determined by the Oldfield questionnaire and evaluated using the Geschwind score. After photocopy images of the two hands of the athletes were taken, their finger lengths were measured Hand grip strength was determined by a Jamar hydraulic dynamometer. Strong correlation was found especially between 2D: 4D and dominant hand grip strength in male and female elite handball players. The ratio of left-handedness due to the positions of players during the game among male and female athletes has been found to be higher than that of the general population. With regard to gender, 2D: 4D was found to be lower in males than females but hand grip was found to be higher in males than females. Besides, a significant correlation between height and BMI with 2D:4D, sport age, height, body weight and hand grip strength was found. This study emphasizes the importance of 2D: 4D, handgrip strength and hand preference in handball.

Attempted Replication

A double-blind experiment with 50 adults was conducted to replicate a finding that proximity to sugar reduces human grip strength. Grip strength of the dominant hand was measured by a chart-recording hand dynamometer for 12 trials. For half of the trials, the subject held an opaque, sealed bottle containing sugar; for half of the trials, the subject held a control bottle of equal weight containing sand. Statistical analysis indicated no significant effect of held substance upon grip strength.

Aim: The purpose of this study is to determine the relationship between isokinetic wrist muscle strenght and grip strength in tennis players aged between 12-14. Methods: This study was carried out with the participation of 9 (3 female and 6 male) tennis players aged between 12-14 (means 13,22±0,83). Weight, height, body mass index and dominant extremity of the players were recorded. İsokinetic measurement was performed with Isomed 2000® device. İsokinetic testing protocol; before the test all players performed the wrist flexion and extension isokinetic test with the 5 repeating at 90 º/sec as a warm-up and for comprehenting the test. Then, wrist flexion and extension concentric-concentric strength measurements were performed with the 5 repeating at 60 º/sec and with the 15 repeating at 240 º/sec with the angle between 50 degrees of wrist flexion and 60 degrees of wrist extension and peak torque values were recorded. Standard Jamar® Dynamometer was used for grip strength measurements. Grip strenght was performed firstly in sitting position, which is the position of standard measurement. Secondly, in standing position, the elbow was in full ekstansion and the forearm was in neutral position. Thirdly, in standing position the wrist was positioned approximately 30° extension and 10° ulnar deviation. This test was repeated 3 times in all test position and the mean of three scores were recorded. Firstly, the dominant hand, then the non-dominant hand was evoluated. They were allowed to rest for 30 seconds between each grip measurement. Correlation between peak tork of isokinetic muscle strenght and grip strength was done having been used Spearman correlation test. Findings: It was determined that there was a significant positive relation between wrist flexion-extension isokinetic muscle strength and grip strenght in tennis players aged between 12-14. Clinically, grip strength measured in the standard sitting position was found more as compared to the other positions but these values were not statistically significant (p>0,05). Accordingly, grip strength measured in the standard sitting position correlated with much more of the parameters which we evaluated for isokinetic muscle strength comparing to grip strenght measured in the other two positions (p<0,05). Results: It was concluded that isokinetic muscle strength of wrist can be affected by grip strength, therefore measurement needs to be done in the sitting position which maximum grip strength may reveal.

Background. Neurorehabilitation interventions in children with unilateral cerebral palsy (UCP) target motor abilities in daily life yet deficits in hand skills persist. Limitations in the less-affected hand may affect overall bimanual hand skills. Objective. To compare hand function, by timed motor performance on the Jebsen-Taylor Test of Hand Function (JTTHF) and grip strength of children with UCP to children with typical development (CTD), aged 8 to 18 years old. Exploratory analyses compared hand function measures with regard to neurophysiological outcomes measured by transcranial magnetic stimulation and between group comparisons of hemispheric motor threshold. Methods. Baseline hand skills were evaluated in 47 children (21 UCP; 26 CTD). Single-pulse transcranial magnetic stimulation testing assessed corticospinal tract and motor threshold. Results. The mean difference of the less-affected hand of children with UCP to the dominant hand of CTD on the JTTHF was 21.4 seconds (95% CI = 9.32-33.46, P = .001). The mean difference in grip strength was −30.8 N (95% CI = −61.9 to 0.31, P = .052). Resting motor thresholds between groups were not significant, but age was significantly associated with resting motor threshold ( P < .001; P = .001). Children with UCP ipsilateral pattern of motor representation demonstrated greater mean differences between hands than children with contralateral pattern of motor representation ( P < .001). All results were adjusted for age and sex. Conclusions. The less-affected hand in children with UCP underperformed the dominant hand of CTD. Limitations were greater in children with UCP ipsilateral motor pattern. Rehabilitation in the less-affected hand may be warranted. Bilateral hand function in future studies may help identify the optimal rehabilitation and neuromodulatory intervention.

The Mean

Grip strength is an important measure used to monitor the progression of a condition, and to evaluate outcomes of treatment. We assessed how various physical and social factors predict normal grip strength in an adult Malaysian population of mixed Asian ethnicity (254 men, 246 women). Grip strength was recorded using the Jamar dynamometer. The mean grip strength for the dominant hand was 29.8 kg for men and 17.6 kg for women. Multiple regression analysis demonstrated that the dominant hand grip strength was positively associated with height and body mass index, and negatively associated with age for both sexes. Dominant hand grip strength was related to work status for men ( p < 0.05) but not for women. However, there was no difference in grip strength among ethnic groups.
