Finally, we compared our values to those from three studies which considered age-related differences in grip strength during the decline phase. 0000006896 00000 n Department of Epidemiology and Public Health, University College London, London, United Kingdom. 0000001718 00000 n Results are expected to differ between male and females, between left and right (dominant and non-dominant) hands, and with age. No, Is the Subject Area "Epidemiology of aging" applicable to this article? "How forearm position affects grip strength." We defined a T-score for grip strength as an individuals value expressed as a multiple of the number of standard deviations below the peak mean value encountered in young adult life. The TILDA study in Ireland [11] stratified values into two height groups; our values were around 15% higher the average of the groups. Pleasee-mail us!

For all subjects, Jamar dynamometer is set at the level II. We have combined data from 12 general population studies conducted in GB to produce normative data for grip strength across the life course. The second study was the meta-analysis by Bohannon et al [12] which combined data from a range of studies in developed country settings. (2008). Then they declined gradually thereafter. However as the aim of this paper was to produce normative data for current use, the recent period of data collection seems appropriate. (2009). [11] where there were only 2 left hand dominant individuals out of 477). Among 235 male patients, 213 patients (90.6%) were right hand dominant and 22 patients (9.4%) were left hand dominant. 0000010747 00000 n Jamar dynamometer and pinch gauge have been found to give the most accurate and acceptable measures of grip and pinch strength respectively. Existing normative data have focussed mainly on older ages [11] with relatively few studies examining childhood, adolescence, and early adult life. Our objective was to produce cross-sectional centile values for grip strength across the life course. Toll-Free U.S. "Estimating minimal clinically important differences of upper-extremity measures early after stroke." This is the first study to provide normative data for grip strength across the life course. It is also important for any sport in which the hands are used for catching, throwing or lifting.

M., Mercier, C., et al. [1] reported that dominant hand was 5-10% stronger than non-dominant hand and can be stronger up to 30%. 5OP@V+oVjqDz q{f2c!j [11] reported that all pinch strengths peaked in thirties except key pinch in men (peaked in forties : 8.32.3kg) and tip pinch in women (peaked in twenties : 3.91.5kg) and tripod pinch was the strongest among them. The study included 515 volunteers older than 10 years, 235 male (45.6%) and 280 female (54.4%). It may therefore be that a T-score of 2.5 (equivalent to 16 kg in females and 27 kg in males) produces a more discriminatory cut-off for weak grip with 23.0% of males and 26.6% of females at or below this level at age 80. xZs6*|dRkPJ>w!,L&x!1RYHjuvm[~]=~W*{ Bx!'K4Hw{7a9p0 D%iDVz'|SmTNr 3{YJUU|}tJe 8[P Eight of the twelve studies had measured grip strength in mid-late adult life, as reflected by the median age of the observations: 58 years (IQR 3669 years). (2000). Sensitivity analyses suggested our findings were robust to differences in dynamometer type and measurement position. Richards, L. G., Olson, B., et al. 0000053789 00000 n "Validity of the Dexter Evaluation System's Jamar dynamometer attachment for assessment of hand grip strength in a normal population." Several attempt is usually required to get the maximum score. We used restricted cubic splines to model the relationship between age and each of the three model parameters: the median, variation and skewness. All data used for this study are owned by third parties. (r = .84) (Figure 4). Bohannon et al [12] have previously combined data from 12 studies in adulthood; however, these studies were predominantly modestly-sized samples drawn from the USA. [10] reported that repeated measuring of hand strength more than 2 times can cause fatigue and was not beneficial than a single measurement. Arch Phys Med Rehabil 89(9): 1693-1700. Grip strength is a key component of the sarcopenia and frailty phenotypes and yet it is unclear how individual measurements should be interpreted. First, we included data from many large general population studies in GB covering all stages of the life course. The prevalence of weak grip increased rapidly in late adult life; using a T-score of 2.5, our results suggested that by age 80, around a quarter had weak grip strength (23.0% of males and 26.6% of females).

Journal of hand therapy 18(4): 426-428. No, Is the Subject Area "Cohort studies" applicable to this article? First, the grip strength of the right and the left hand were measured, subsequently the tip pinch of the right and the left hand were measured. 0000126999 00000 n The MRC National Survey of Health and Development is funded by the UK Medical Research Council. There have been various methods for the evaluation of grip and pinch strengths. vk0(Hb/I2. Taken together, this meant that the total number of grip strength values we could use in analyses varied: either three (ADNFS and LBC1921), four (N85 and the first wave of NSHD) or six (the remainder). This measuring tools should be performed by having the patients in seated position with the shoulder adducted, not rotated to either side, and the elbow flexed to 90 degrees with the forearm and wrist in neutral position, as recommended by the American Society of Hand Therapist. Figure S2, Centiles stratified by dynamometer type. It showed that tip, key and tripod pinch strengths had a positive linear correlation with the grip strength. Values shown in brackets are the gender-specific cut-off values calculated by subtracting the relevant number of standard deviations (2 or 2.5) from the young adult peak mean. We have shown that grip strength increases to a peak in early adult life, and is then followed by a period of broad maintenance prior to decline with increasing age. Philanthropic support truly drives our mission and vision. Data Availability: The authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. here. Seven studies used the Jamar dynamometer (including the second wave of HAS, which used the Harpenden dynamometer at the first wave), two studies (ELSA and UKHLS) used the Smedley dynamometer, two studies used the Nottingham electronic dynamometer (ADNFS and NSHD), and N85 used the Takei dynamometer.

Fourteen subjects, although left hand dominant, said that they were taught and forced to use the right hand, and thus could not say which one was dominant. No, Is the Subject Area "Longitudinal studies" applicable to this article? For more information about PLOS Subject Areas, click Fluctuation in grip and pinch strength amongnormal subjects. Right hand dominant individuals: Comparisons between the left and right hands of right hand dominant individuals demonstrated that the right hand was stronger than the left hand in all measures that we performed (grip strength and 3 types of pinch strengths) and the differences were statistically significant via paired t-test (p < .05) (Figure 5) The average of the left grip strength was 94.05% of the right grip strength. stream Copyright: 2014 Dodds et al. However they can be influenced by many factors such as hand size, the forearm circumference, height, weight, occupation, level of physical activities. We therefore always used the maximum of these values for our analyses, since the maximum is less likely to be affected by the number of trials than the mean [26]. "Hand dynamometer: effects of trials and sessions." It appears that normal Korean grip and pinch strengths are improved and are closed to the average of Caucasians. The subject is in a seated position with the shoulder adducted, not rotated to either side, and the elbow flexed to 90 degrees with the forearm and wrist in neutral position (Figure 1 & Figure 2).

Make the best use of Scientific Research and information from our 700 + peer reviewed, Open Access Journals. Grip strength is associated with a variety of ageing outcomes [1][3] and forms a key component of sarcopenia [4] and frailty [5], [6] phenotypes. The normative values from the fourth study [38], based in Switzerland, were on average 11% higher than ours. The age of the male patients ranged from 10 to 78 years with the mean age of 40 years, and the age of the female patients ranged from 14 to 84 years with the mean age of 44 years. We considered differences between previously published mean values and our median values for grip strength at a selection of ages, expressed as a percentage of our value. Males reached a peak median grip of 51 kg (to the nearest whole kg) between ages 29 and 39, compared to the peak female median grip of 31 kg between ages 26 and 42.

RC and DK are supported by the UK Medical Research Council (programme code MC_UU_12019/4). These centile values have the potential to inform the clinical assessment of grip strength which is recognised as an important part of the identification of people with sarcopenia and frailty. Second, we used a modelling approach which allowed grip strength to vary as a smooth function of age and to incorporate any non-normality in grip (skewness or kurtosis). Find it on PubMed. This study had some limitations. To keep up with the latest in sport science and this website, subscribe to our newsletter. So, we measured grip and pinch strengths twice with one minute of break between each measure and the average scores were used in this study.
