Description Objective: Hand grip strength can provide an objective index of general upper strength, but hand dynamometer has not been validated for use in Colombia. The objective was to determine the interchangeability between Camry electronic and Jamar hydraulic hand grip dynamometers in a population found on the campus of the Universidad Nacional de Colombia and the elderly living in a community.
Methods: This was a cross-sectional concordance study on 18-88-year-old males and females. Data regarding their demographics, health, and anthropometric variables were collected/measured and the Lin concordance correlation coefficient (CCC) along with Bland-Altman plots were used for evaluating concordance regarding both devices.
Results: One hundred and thirty-three subjects participated in this study (average age 47±20.74 years-old). Right hand (RH) grip strength was 32.15 ± 9.96 kg with the Jamar dynamometer and 29.95 ± 9.18 kg with the Camry device. It is worth highlighting that the Jamar instrument presents higher values than the Camry instrument (p <0.05). CCC was only significant at the population level and for the 40-59-year-old age group. Bland-Altman plots had narrow limits of agreement.
Conclusion: We concluded that the Camry dynamometer could replace the Jamar dynamometer in the 40-59-year-old age group; furthermore, it would be appropriate for medical use in patient monitoring or follow-up due to the close values observed.
Objetivo. La fuerza de agarre de la mano puede proporcionar un índice objetivo de la fuerza de los miembros superiores, pero no se dispone de un dinamómetro de mano validado para su uso en Colombia. El objetivo fue determinar la intercambiabilidad entre los dinamómetros hidráulicos Jamar y el dinamómetro electrónico Camry en una población que se encuentra en el campus de la Universidad Nacional de Colombia y personas mayores que viven en una comunidad.
Métodos. Estudio transversal de concordancia realizado en hombres y mujeres de 18 a 88 años de edad. Se recolectó información sobre variables demográficas, de salud y antropométricas. El coeficiente de correlación de concordancia de Lin (CCC) y los gráficos de Bland-Altman se utilizaron para evaluar la concordancia entre ambos dispositivos.
Resultados. Participaron 133 sujetos (edad promedio de 47 ± 20,74 años). La fuerza de agarre de la mano derecha fue de 32,15 ± 9,96 kg con el dinamómetro Jamar y de 29,95 ± 9,18 kg con el dispositivo Camry, destacando que el equipo Jamar presenta valores superiores al Jamar (p<0.05). La CCC solo fue significativa a nivel de la población y para el grupo de edad de 40 a 59 años. Los gráficos Bland-Altman presentaron límites de acuerdo estrechos.
Conclusión. Concluimos que el dinamómetro Camry podría reemplazar el dinamómetro Jamar en el grupo de edad de 40-59 años; además, sería apropiado para uso médico en el monitoreo o seguimiento de pacientes debido a los valores cercanos observados.
