| Summary |
It was hypothesized that aging modifies the oscillatory input between agonist and antagonist muscle pairs during gait. The purpose of the current study is to compare muscle-to-muscle coherence between old and young individuals during gait in different intensities and tasks. EMG data was collect during treadmill walking of antagonistic leg muscles during gait of young and old individuals. The EMG signals' frequency was analyzed using a coherence analysis. The data revealed that the young subjects exhibited statistically significant greater levels of in 4 out of the 6 frequency bands examined. The old adults showed an inability to modulate levels of coherence during differing tasks and intensities. It is thought this insensitivity in modulating coherence demonstrates lower levels of control of and functional connectivity to agonist/antagonist muscle pairs. These data suggest that age affects the functional organization of human voluntary movement. |
