          Abstract

          Abstract Background and objectives: The objective of this study was to establish reference values for hand grip strength, compare the results obtained with Collin and Jamar type dynamometers and determine their association with anthropometric and lean mass measurements. Material and methods: This cross-sectional population-based study was undertaken in Pizarra (Málaga, Spain). The grip strength of the dominant hand was measured using Collin and Jamar dynamometers. Skinfolds (triceps, abdominal, biceps of dominant arm and subscapular) were measured, and body composition was estimated. Eight hundred seventeen adults randomly selected from the census were recruited. Dynamometry reference values are presented for the dominant hand, by gender and age groups. Results: No determinations could be made with the Collin dynamometer in 69 women due to the difficulty in grasping the dynamometer. We found significant positive correlations between the measurements with Jamar and Collin dynamometers (r = 0.782; p < 0.001) and between grip strength and lean mass index (LMI), determined by both dynamometers (r = 0.538, p < 0.001 and r = 0.462, p < 0.001, respectively). Malnourished patients according to LMI had significantly lower grip strength than normally nourished patients (p < 0.001 for Jamar; p < 0.02 for Collin). Conclusions: Dynamometry reference values in the Spanish population are presented. We recommend the use of the Jamar type dynamometer versus the Collin type dynamometer. Hand grip dynamometry is associated with lean mass, which confirms its usefulness in nutritional assessment.

          Resumen Antecedentes y objetivos: no existen valores de normalidad en España con el dinamómetro Jamar. El objetivo fue determinar valores de normalidad de fuerza muscular, comparar los resultados obtenidos con los dinamómetros tipo Collin y tipo Jamar entre sí, y determinar su asociación con medidas antropométricas y de masa magra. Material y métodos: estudio transversal de base poblacional en Pizarra (Málaga). Se determinó la fuerza de prensión de la mano dominante mediante dinamómetros Collin y Jamar. Se midieron los pliegues cutáneos (tricipital, abdominal, bicipital del brazo dominante y subescapular) y se estimó la composición corporal. Se reclutaron 817 adultos seleccionados aleatoriamente del censo. Se presentan valores de referencia de dinamometría para la mano dominante, por género y grupos de edad. Resultados: no se pudieron realizar determinaciones con el dinamómetro Collin en 69 mujeres debido a la dificultad para agarrar el dinamómetro. Encontramos correlaciones positivas significativas entre las medidas de los dinamómetros Jamar y Collin (r = 0,782; p < 0,001) y entre la fuerza muscular determinada mediante ambos dinamómetros y el índice de masa magra (IMM) (r = 0,538, p < 0,001 y r = 0,462, p < 0,001, respectivamente). Los pacientes desnutridos según IMM presentaron una fuerza muscular significativamente menor a la de los pacientes normonutridos (p < 0,001 para Jamar y p < 0,02 para Collin). Conclusiones: se presentan valores de referencia de dinamometría en población española. Recomendamos el uso del dinamómetro tipo Jamar frente al dinamómetro tipo Collin. La dinamometría de mano se asocia con la masa magra, lo que avala su utilidad en la valoración nutricional.

            Hand grip strength: outcome predictor and marker of nutritional status.

            Among all muscle function tests, measurement of hand grip strength has gained attention as a simple, non-invasive marker of muscle strength of upper extremities, well suitable for clinical use. This review outlines the prognostic relevance of grip strength in various clinical and epidemiologic settings and investigates its suitability as marker of nutritional status in cross-sectional as well as intervention studies. Studies investigating grip strength as prognostic marker or nutritional parameter in cross-sectional or intervention studies were summarized. Numerous clinical and epidemiological studies have shown the predictive potential of hand grip strength regarding short and long-term mortality and morbidity. In patients, impaired grip strength is an indicator of increased postoperative complications, increased length of hospitalization, higher rehospitalisation rate and decreased physical status. In elderly in particular, loss of grip strength implies loss of independence. Epidemiological studies have moreover demonstrated that low grip strength in healthy adults predicts increased risk of functional limitations and disability in higher age as well as all-cause mortality. As muscle function reacts early to nutritional deprivation, hand grip strength has also become a popular marker of nutritional status and is increasingly being employed as outcome variable in nutritional intervention studies.

              Age-associated changes in skeletal muscles and their effect on mobility: an operational diagnosis of sarcopenia.

              Sarcopenia, the reduction of muscle mass and strength that occurs with aging, is widely considered one of the major causes of disability in older persons. Surprisingly, criteria that may help a clinician to identify persons with impaired muscle function are still lacking. Using data from a large representative sample of the general population, we examined how muscle function and calf muscle area change with aging and affect mobility in men and women free of neurological conditions. We tested several putative indicators of sarcopenia, including knee extension isometric torque, handgrip, lower extremity muscle power, and calf muscle area. For each indicator, sarcopenia was considered to be present when the measure was >2 SDs below the mean. For all four measures, the prevalence of sarcopenia increased with age, both in men and women. The age-associated gradient in prevalence was maximum for muscle power and minimum for calf-muscle area. However, lower extremity muscle power was no better than knee-extension torque or handgrip in the early identification of poor mobility, defined either as walking speed <0.8 m/s or inability to walk at least 1 km without difficulty and without developing symptoms. Optimal cutoff values that can be used in the clinical practice to identify older persons with poor mobility were developed. The findings of the study lay the basis for a cost-effective, clinical marker of sarcopenia based on a measure of isometric handgrip strength. Our findings should be verified in a longitudinal study.
