Handgrip Fix



Handgrip strength is an important biomarker of healthy ageing and a powerful predictor of future morbidity and mortality both in younger and older populations. Therefore, the measurement of handgrip strength is increasingly used as a simple but efficient screening tool for health vulnerability. This study presents normative reference values for handgrip strength in Germany for use in research and clinical practice. It is the first study to provide normative data across the life course that is stratified by sex, age, and body height. The study used a nationally representative sample of test participants ages 17-90. It was based on pooled data from five waves of the German Socio-Economic Panel (2006-2014) and involved a total of 11,790 persons living in Germany (providing 25,285 observations). Handgrip strength was measured with a Smedley dynamometer. Results showed that peak mean values of handgrip strength are reached in men's and women's 30s and 40s after which handgrip strength declines in linear fashion with age. Following published recommendations, the study used a cut-off at 2 SD below the sex-specific peak mean value across the life course to define a 'weak grip'. Less than 10% of women and men aged 65-69 were classified as weak according to this definition, shares increasing to about half of the population aged 80-90. Based on survival analysis that linked handgrip strength to a relevant outcome, however, a 'critically weak grip' that warrants further examination was estimated to commence already at 1 SD below the group-specific mean value.

Mean HGS was significantly higher in the survivors (24.235.86) compared to non- survivors (18.044.82) (P=0.0011). When handgrip was quantified in the deceased and the patients still alive, significant difference was found (Table 2). Mean HGS in deceased patients was 18.044.82 kg and HGS in patients still alive was 24.235.86 kg (P=0.001). Multivariate logistic regression analysis to assess the risk factors for death showed handgrip to be in the suggestive significance range (P=0.072) (Table 3).


Functional loss in malnourished patients is attributed to decreased body cell mass. Therefore, use of a technique capable of assessing functional capacity is of paramount importance [12] and helps detect malnutrition at an early stage. To satisfy these requirements, HGD is a reliable method which can assess the muscle strength and functional capacity [13]. HGD is tool for the nutritional screening and has been used in diagnosis of malnutrition in healthy populations [14] and hospitalized individuals [12]. HGS was used as a proxy for muscle strength in many studies as mentioned in previous literature [15]. In the study of Alvares-da-Silva et al, HGD was reported as a simple method to detect malnutrition among patients who are at nutritional risk, and after comparison with SGA they have concluded that handgrip examination can be considered a reliable method to identify malnutrition and is easy to perform [16].


In our study handgrip was strongest in CTP class A followed by CTP class B and C, suggesting the inverse relation between HGS and CTP score. Abbott et al found an association of reduced muscle mass with higher CTP score and showed an increase in total morbidity as well as early morbidity in post-liver transplantation patients. Reduced HGS was associated with increased duration of hospitalization, increased postoperative complications, higher numbers of rehospitalization and decreased physical capability [4].


Our study has a number of limitations. Subjective components in the SGA may differ amongst individuals so classifying patients according to SGA class is difficult. On multivariate analysis handgrip showed a trend towards significance (suggestive significance) but not statistical significance. Futures larger studies and with a longer duration are required to accurately validate the accuracy of HGD in predicting mortality.


Subjects and methods: Descriptive study of 517 healthy volunteers (267 females and 229 males) aged 17-97 years. Grip strength was measured using two different handgrip dynamometers. Three consecutive measurements were made in both the dominant and the non-dominant hands. The results were analysed after stratification by age, gender, weight, height and dominant/non-dominant hand.


Conclusions: Normal reference values for handgrip strength should be established and stratified according to age and gender. The variations associated with height do not warrant adjustments in relation to this variable.


Objectives: To test the hypothesis that ICUAP is independently associated with increased mortality. Secondarily, to determine if handgrip dynamometry is a concise measure of global strength and is independently associated with mortality.


Measurements and main results: We measured global strength and handgrip dynamometry. The primary outcome was in-hospital mortality and secondary outcomes were hospital and ICU-free days, ICU readmission, and recurrent respiratory failure. Subjects with ICUAP (average MRC score of


Previous studies have relied either on cross-sectional or prospective cohort models and have focused mostly on a specific country, "not accounting for time-varying changes of both handgrip strength and relevant covariables."


Moreover, previous evidence has been mixed regarding the "extent to which handgrip strength levels may associate with lower risk of depression, with study results ranging from weak to strong associations," the investigators write.


Overall, the findings "warrant strength training programmes aimed at older adults to reduce depression risk," the investigators write. Clinicians "may consider using the observed handgrip strength thresholds to screen for potential depression risk in older adults," they add.


A team led by researchers from North Dakota State University looked at data over an eight-year period from almost 14,000 people, age 50 or older, in the NIA-supported Health and Retirement Study. A handheld instrument called a dynamometer was used to assess handgrip strength, and a modified screening tool from the Mini-Mental State Examination was used to measure cognitive function every two years. Of the 13,828 participants who were assessed, 1,309 had some degree of cognitive impairment.

The purpose of the handgrip strength test is to measure the maximum isometric strength of the hand and forearm muscles. Handgrip strength is important for any sport in which the hands are used for catching, throwing or lifting. Also, as a general rule people with strong hands tend to be strong elsewhere, so this test is often used as a general test of strength. See also the finger pinch strength test.

The handgrip maneuver is performed by clenching one's fist forcefully for a sustained time until fatigued. Variations include squeezing an item such as a rolled up washcloth.[citation needed]


There is a wide variety of tests and tools available for sarcopenia stratifications in clinical practice and in research6,7. According to the European Working Group on Sarcopenia in Older People (EWGSOP2), sarcopenia diagnosis is based on parameters of skeletal muscle mass and strength, and physical performance1. In clinical practice, for sarcopenia screening and diagnosis, EWGSOP2 recommends the use of muscle strength tests such as handgrip strength (HGS) to identify probable presence of sarcopenia8. HGS is an easy measure with practical applicability and is associated with lower limb strength and disability9. The use of dual-energy X-ray absorptiometry (DXA) is recommended to detect low skeletal muscle quantity10. In addition, physical performance measures are often used to determine sarcopenia severity1.


The general characteristics of the participants showed differences between the groups regarding anthropometric variables and body composition due to sarcopenia. These findings are consistent with previous studies on aging sarcopenia36,37. Regarding muscle strength, both handgrip strength and respiratory muscle strength were lower in individuals with sarcopenia when compared to the non-sarcopenic elderly. Thus, the data of the present study is in accordance with the findings of previous studies that identified lower MIP, MEP, and HGS in older adults with sarcopenia1,8,22,24,38. 041b061a72
