Analysis of the Relationships between Balance Ability and Walking in Terms of Muscle Activities and Lower Limb Kinematics and Kinetics

There is a lack of evidence about the ways in which balance ability influences kinematic and kinetic parameters muscle activities during gait among healthy individuals. The hypothesis that would be associated with lower limb kinematics, kinetics gait. Twenty-nine volunteers (Age 32.8 ± 9.1; 18 males 11 females) performed Star Excursion Balance test to measure their dynamic walked for at least three trials order obtain good quality data. A Vicon® 3D motion capture system AMTI® force plates were used collection movement selected recorded using Delsys® Electromyography (EMG). EMG compared maximum values root mean squared (RMS) within participants. joint angle, moment, power calculated Vicon Plug-in-Gait model. Descriptive analysis, correlation analysis multivariate linear regression SPSS version 23. In activities, positive correlations found between walking all muscles, e.g., multifidus (r = 0.800 p < 0.0001), vastus lateralis 0.639, 0.0001) tibialis anterior 0.539, 0.0001). models showed there was strong association (i.e., reaching distance) medialis–RMS) (R 0.885, also kinematics 0.906, conclusion, results medialis activity mainly contributes ability,
