Investigation of fall prediction factors in elderly population using isokinetic assessment of the lower extremities
Journal Title: Biology of Exercise - Year 2011, Vol 7, Issue 2
Abstract
The purpose of the present study was to investigate for predictive factors for falls in elderly population after lower extremity strength assessment in an isokinetic dynamometer. 59 community dwelling elderly men and women aged 60 years and older with or without a history of falls all in good health were selected to participate in the study. For the assessment, we used six concentric and two eccentric speeds isokinetically and four different angular positions isometrically. All measures were conducted with a Cybex Norm® Isokinetic Dynamometer in the knee joint for both legs in flexion and extension. Stepwise discriminant analysis performed in order to reveal the factors for classification of the elderly in fallers / non - fallers group. Three variables out of the initially 42 that included in the discriminant analysis were present in the discriminant model: Mean peak torque in 120°/sec in extension, mean total work in 60°/sec in flexion and mean total work ratio in 60°/sec and classified correctly the 91.4% of the cases in the fallers/non - fallers groups. The researchers concluded that isokinetic and isometric assessment of the lower extremities strength in the elderly population can discriminate fallers from non - fallers.
