“…Second, the Jamar hydraulic hand dynamometer is the gold standard for measuring HGS, 22 but we used a different digital hand dynamometer. However, a study that compared the Camry and Jamar dynamometers in healthy adults aged 40–59 years showed that the Camry could replace the Jamar dynamometer 23 . Third, we could not examine physical performance, such as 6‐min walk distance, because many participants were too old to safely undergo the test.…”

Background Sarcopenia is a major component of geriatric syndrome and associated with poor clinical outcomes and mortality. However, diagnosing sarcopenia in the very elderly is difficult, and data on its epidemiology and devastating effects in this group are scarce. Phase angle (PA) is measured using bioimpedance spectroscopy and known to reflect cellular integrity and health. This study aimed to clarify the impact of sarcopenia and PA on mortality risk in very elderly people living in long‐term care facilities. Methods This prospective cohort study enrolled elderly residents living in nine long‐term care facilities. We collected the participants' data, such as body mass index (BMI), comorbidities and laboratory data, from September to October 2017 and mortality data until October 2019. Nutritional status was evaluated using the Mini Nutritional Assessment (MNA) score, and multifrequency bioimpedance spectroscopy was used to assess body composition including PA. Appendicular skeletal muscle mass was calculated using the body composition monitor‐derived equation of Taiwan's researchers. Sarcopenia was diagnosed using the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) definition (sarcopenia vs. normal group). We divided the participants into two groups according to the median PA value of 3.65° (high vs. low group) and performed multivariate regression analyses to verify the association with mortality risk according to sarcopenia diagnosis or PA group. Results A total of 279 elderly participants were enrolled; of them, 238 (85.3%) were diagnosed with sarcopenia according to EWGSOP2 guidelines. The median patient age was 83 years, 211 (75.6%) were female and the median BMI was 20.4 kg/m2. The sarcopenia group was older than the normal group (84 vs. 81 years; P = 0.002), had a lower mean BMI (19.8 vs. 26.6 kg/m2, P < 0.001) and had a lower MNA score (9 vs. 12 points, P < 0.001). Sarcopenia was associated with a higher mortality risk after the adjustment for age, sex and diabetes mellitus (hazard ratio [HR], 3.744; 95% confidence interval [CI], 1.155–12.134; P = 0.028). A low PA was associated with sarcopenia, older age, female sex, low MNA score and overhydration volume; it was also a significant predictor of mortality after the adjustment for age, sex, diabetes mellitus and MNA score (HR, 0.593; 95% CI, 0.420–0.837; P = 0.003). Conclusions Sarcopenia is prevalent among the very elderly patients in long‐term care facilities. Sarcopenia and low PA are significantly associated with higher mortality risk.

“…There was a nonsignificant mean difference in readings between the two devices, with the Jamar ® results being marginally higher than the Camry results. This could be attributed to the difference in mechanism and shape of the devices and the feedback that each provides (Amaral, Mancini & Novo 2012 ; Díaz Muñoz & Calvera Millán 2019 ). A number of participants reported differences in tactical feedback between the devices.…”

“…The Camry Digital Handgrip Dynamometer has occasionally been reported in the literature; however, its validity in different populations remains unclear (Wilkinson et al 2021 ). A recent study conducted on healthy individuals and community-dwelling elderly individuals in Colombia comparing the Camry Digital Handgrip Dynamometer to the Jamar ® found significant concordance and agreement between devices, most notably in those aged 40–49 years (Díaz Muñoz & Calvera Millán 2019 ). To the best of our knowledge, the Camry Digital Handgrip Dynamometer has not been validated in a clinical setting.…”

Background: Grip strength has been identified as an important indicator of health status and predictor of clinical outcomes. The gold standard for measuring grip strength is the JAMAR® Hydraulic Hand Dynamometer. Less expensive dynamometers are available but have not been validated within a hospital setting.Objectives: To validate the Camry Digital Handgrip Dynamometer (Model EH101) against the validated JAMAR® Dynamometer (Model J00105) in a hospital population.Methods: A cross-sectional observational study with a randomised single-blind cross-over component was conducted on consenting adult patients admitted to general hospital wards. The best of three measurements taken using the dominant hand was used for analysis.Results: Fifty-one participants (median [interquartile range] age 42 [30–58] years; n = 27 [52.9%] female) were included. The mean difference between the Jamar® and Camry measurements was 1.9 kg ± 3.6 kg (t-value 0.9; p = 0.4). There was a strong positive correlation between the Jamar® and the Camry devices (R = 0.94; r² = 0.88; p 0.0001). Excellent agreement was found between Jamar® and Camry measurements (interclass correlational coefficient 0.97, 95% CI 0.94–0.99, p 0.0001). Hand dominance significantly affected the agreement between devices (p = 0.002).Conclusions: The Camry Digital Handgrip Dynamometer is a valid tool for assessing grip strength in hospitalised adult patients.Clinical implications: The Camry Digital Handgrip Dynamometer could be used as an inexpensive tool to measure grip strength.

“…There is increasing evidence with the Camry dynamometer used to measure muscle strength (LinY et al 2021 ; Park et al 2019 ; Mendes et al 2020 ). However, there is scarce evidence that demonstrates that Camry dynamometer is a reliable device in the geriatric population (Muñoz and Millán 2019 ; Huang et al 2022 ), and to our knowledge no previous studies in a preoperative setting.…”

Background Handgrip strength is a useful measurement of muscle strength and has been proposed as a single predictor of postoperative outcomes in older adults. The aim of this study was to assess the correlation and concordance of Camry digital hand grip dynamometer (EH101) with gold standard Jamar® hydraulic handgrip dynamometer in older adults previous to elective surgery. Methods A cross-sectional study was conducted on patients ≥ 65 years old admitted to a Chilean private hospital for elective surgery between March 2018 and February 2019. Handgrip strength was assessed 2 times with each hand prior to surgery, using both the Jamar® dynamometer and the Camry digital dynamometer. The highest value of each dynamometer was used for analysis. Results We included a total of 220 patients (mean age 73.1 years old ± 6.3). Maximal handgrip strength averaged 26.9 kg ± 9.6 with the Camry dynamometer and 26.9 kg ± 9.7 with the Jamar® dynamometer in the right hand and 25.5 kg ± 9.5 with the Camry dynamometer and 25.7 kg ± 9.2 with the Jamar® dynamometer with the left hand. The difference between both measures did not differ significantly from 0, with Pearson correlation index of 0.95 and Lin’s concordance index of 0.95 (p < 0001). The Bland–Altman graphics show that 90% of the measures were inside the confidence limits, without systematic bias. Conclusion Camry digital dynamometer is an inexpensive and valid device to measure handgrip strength in older adults previous to elective surgery, compared to the gold standard Jamar® hydraulic handgrip dynamometer.
