The lower extremity dexterity test as a measure of lower extremity dynamical capability.

摘要: The capability of the lower extremity to dynamically interact with ground is important for skilled locomotor performance. However, there currently no test method designed specifically quantify this sensorimotor ability, which we refer as dexterity. We describe a new dexterity, examine its reliability (n¼ 10), and evaluate extent it associated strength anthropometry in healthy young adults 38). dexterity (LED-test)—an adaptation Strength–Dexterity fingers– consists using isolated compress slender spring prone buckling at low forces. goal LED-test sustain highest compression force possible. Applying higher forces makes increasingly unstable, thus achieving represents better ability control instability levels. As such, provides novel way regulate dynamic unstable footground interactions submaximal performance ranged between 88.6 119.6 N, test-retest was excellent (ICC (2,3) ¼ 0.94), minimal detectable difference 5.5 N. Performance not correlated or height (r 2 r 0.053, p4 0.05), only weakly body mass 0.116, p ¼0.04). propose that unique quantified by could be informative injury risk.
