What percentage of the gait cycle is constituted by the swing phase?

The swing phase of the gait cycle typically comprises approximately 40% of the entire cycle. This phase begins when the foot leaves the ground and ends when the foot is set to make contact again. During the swing phase, the leg moves forward to prepare for the next step, allowing the individual to cover ground while the opposing leg is in the stance phase. This movement is crucial for maintaining forward momentum and balance during walking or running.

In understanding the percentages of the gait cycle, it is helpful to note that the gait cycle is divided into two main phases: the stance phase and the swing phase. The stance phase accounts for the remaining 60% of the gait cycle, as it involves various actions such as weight acceptance, single limb support, and pre-swing.

Recognizing that the swing phase constitutes around 40% supports a comprehensive understanding of the mechanics of walking, which is essential for physical therapy assessment and treatment strategies related to mobility and ambulation.
