“…Several small studies (with 104 or fewer participants) have used comparisons of repeat measurements with two or more dynamometers to investigate whether similar readings are produced. Their findings have varied, with some reporting that readings from different dynamometers are comparable [41][42][43][44], or can be converted using an equation [45], and others concluding that the limits of agreement are too broad and the devices are not interchangeable in either way [41,46]. From our results, we conclude that the different dynamometers used produce acceptably similar normative data, albeit within the ages at which measurements were observed.…”

Introduction: Epidemiological studies have shown that weaker grip strength in later life is associated with disability, morbidity, and mortality. Grip strength is a key component of the sarcopenia and frailty phenotypes and yet it is unclear how individual measurements should be interpreted. Our objective was to produce cross-sectional centile values for grip strength across the life course. A secondary objective was to examine the impact of different aspects of measurement protocol. Methods: We combined 60,803 observations from 49,964 participants (26,687 female) of 12 general population studies in Great Britain. We produced centile curves for ages 4 to 90 and investigated the prevalence of weak grip, defined as strength at least 2.5 SDs below the gender-specific peak mean. We carried out a series of sensitivity analyses to assess the impact of dynamometer type and measurement position (seated or standing). Results: Our results suggested three overall periods: an increase to peak in early adult life, maintenance through to midlife, and decline from midlife onwards. Males were on average stronger than females from adolescence onwards: males' peak median grip was 51 kg between ages 29 and 39, compared to 31 kg in females between ages 26 and 42. Weak grip strength, defined as strength at least 2.5 SDs below the gender-specific peak mean, increased sharply with age, reaching a prevalence of 23% in males and 27% in females by age 80.

Introduction. Grip strength is a reflection not only of the strength of the hands, but also the strength of the muscles of the whole body, the functional capabilities of the body and an important diagnostic marker of the overall health of a person. The aim of this work was to compare the measurements obtained with the DK-50 and JAMAR® Plus digital handheld dynamometers.Methods. A convenience sample was used of 94 health participants, men and women, aged from 15 to 65 years old. Grip strength of a dominant hand was conducted using a carpal mechanical dynamometer DK-50 (Nizhni Tagil, Russian Federation) and JAMAR® Plus digital handheld dynamometer. The simple Pearson correlation test, linear regression method and the procedure of Bland and Altman were used to estimate difference between an average value of results of measurements of grip strength (AGS) and maximum measurement of grip strength (MGS) of the dominant hand of two dynamometers.Results. The grip strength using JAMAR® Plus dynamometer was higher than with the DK-50 dynamometer by 5.6 ± 4.2 kg for the average grip strength (AGS) and by 6.7 ± 4.3 kg for the maximum grip strength (MGS). The formulas for transferring the data of the car dynamometry of the DK-50 dynamometer to the values obtained from the JAMAR® Plus dynamometer are calculated: AGS JAMAR® Plus == 1,7874 + 1,1208 × AGS DK-50 and MGS JAMAR® Plus = 1.7667 + 1, 1275 × MGS DK-50.Conclusion. For avoiding errors in the interpretation of the results from different studies, it is necessary to take into account which type of dynamometer was used. The resulting formulas (AGS JAMAR® Plus == 1,7874 + 1,1208 × AGS DK50 and MGS JAMAR® Plus = 1,7667 + 1,1275 × MGS DK50) can be used to correct the data of the dynamometer DK-50 for value of JAMAR® Plus dynamometer and to compare the results of Russian studies with data from foreign studies organized using JAMAR® Plus dynamometers.

“…Os valores encontrados na avaliação do TPP são influenciados por diversos fatores, entre eles o sexo, idade, nível de atividade física e até mesmo a motivação na hora da avaliação [11,12]. Em concordância com achados da literatura, nossos resultados documentaram uma diferença no TPP entre os gêneros, sendo esta maior nos homens [11].…”

Resumo: O dinamômetro analógico manual (DAM) tem sido amplamente utilizado para avaliação do torque de preensão palmar (TPP), trata-se de um equipamento de baixo custo e fácil utilização, entretanto, sua aplicação no meio científico é limitada. Por outro lado, a utilização de um dispositivo de registro eletromiográfico (EMG) com sensor de força digital (SFD), fornece uma avaliação mais completa dos músculos, porém de alto custo. Objetivou-se desenvolver um SFD associado ao registro EMG, de baixo custo e que possa ser comparável ao DAM comercial. As adaptações de hardware incluíram a construção de um dispositivo para captação dos sinais, por meio de uma célula de carga em um apoio anatômico para medição do TPP. O software consiste em um sistema de amplificação e filtragem do sinal elétrico. Para avaliação, foram estudados 63 voluntários, 38 mulheres (20,57±0,87anos) e 25 homens (20,24±0,98anos evaluation, 63 volunteers, 38 women (20.57 ± 0.87 years) and 25 men (20.24 ± 0.98 years) were studied. The forearm circumference and PGT were collected in the dominant limb using ADM and DSS. Largest circumference of the men's forearm was observed in relation to the women (25 ± 0.46 vs 20 ± 0.42cm, p <0.0001). A significant difference was found in the evaluation of PGT between the genders by both ADM (47.15 ± 1.85 vs 29.87 ± 0.67Kgf) and DSS (31.61 ± 0.88 vs 28.65 ± 0 , 62mV). When all patients were evaluated, there was a significant correlation between forearm circumference and ADM (r = 0.62) and DSS (r = 0.44). A significant correlation was observed between TPP measured by ADM and DFS (r = 0.65 IntroduçãoO torque de preensão palmar (TPP) é um parâmetro que mede não somente a força exercida pelos músculos responsáveis por gerar força na mão, mas também, tem sido amplamente utilizado para avaliar a força total do corpo, bem como a redução fisiológica da força corporal total com o envelhecimento [1,2,3].Somado a isto, estudos recentes tem documentado a importância do TPP na identificação de distúrbios musculoesqueléticos, assim como na fragilidade e
