In the past, researchers evaluated walking speed and stride during a gait ability test. However, recently, there have been developed methods which evaluate exercise performance beyond result-based assessment. In the past, the individual ability was estimated according to walking index, but the trend has been gradually expanding the scope of researching boundary with questions on the process of walking. The purpose of this study is to explain the muscle synergies that occur during walking. The muscle synergy refers to a pattern in which various muscles present in the human body are simultaneously activated to achieve a given task. Currently, muscle synergy research is actively underway in the exercise regulation and the neurodynamic field. Theoretically, the number of cases of performing the same task due to the many joint freedom degrees in the human body varies greatly. From this point of view, it can be concluded that the simultaneous activity pattern of muscles can be varied by repeating the task for everyone. However, when the actual muscle activity pattern is analyzed, there is no significant difference between the individuals. Considering that there are few differences among individuals with very important patterns in the task performance process, a common strategy for achieving goals in the central nervous system may be a necessary pattern for the successful execution of specific behaviors. Through this common pattern, spatiotemporal data for muscle synergy can provide the theoretical base for gait training in rehabilitation.
