Kovarik M, et al. - In COPD patients, researchers performed a direct dynamometric assessment of hand grip endurance and strength in relation to the stage of disease, multidimensional predictors of mortality, and 6-minute walk test (6MWT). In comparison with the control group, both hand grip strength and endurance were impaired in COPD patients. They identified that area under the force/time curve could be considered as an attractive option not only to assess exercise capacity but also as a predictive marker with a better prognostic value than 6MWT in COPD patients. This study revealed the dependence of hand grip endurance on combined COPD assessment.
