Quantitative analysis of angular movements of knee during treadmill barefoot walking / N. Lovecchio, D. Galante, M.C. Turci, C. Sforza, V.F. Ferrario. - In: THE OPEN SPORTS MEDICINE JOURNAL. - ISSN 1874-3870. - 2:6(2008), pp. 28-33. [10.2174/1874387000802010028]
Abstract:
Background and Purpose: Cinematic analyses of human walking are widely carried out, but the assessment of
sex-related differences is still incomplete. Knee range of motion was investigated in healthy sedentary subjects during
standardized speed treadmill walking.
Subjects and Methods: One hundred and three subjects aged 20-79 years were filmed by an optoelectronic system. Threedimensional
knee joint angular data were obtained from trajectories of markers using Euler operators.
Results: On average, within sex, flexion-extension and internal-external rotation were symmetric (Watson-Williams'' test,
p > 0.05). During walking, women had a larger knee flexion-extension (mean 67.5°, SD 0.8°) than men (mean 64.8°, SD
0.8°, p < 0.05), but similar internal-external rotation (women, 22.6°, SD 0.6°; men, 21.2°, SD 0.5°). No significant correlations
between movements and age or anthropometric characteristics were found.
Conclusions: In healthy sedentary adults, treadmill walking is performed with knee range of motion that is largely independent
from age, sex or anthropometry.
