In a healthy individual walking at a normal walking speed, stance phase makes up approximately 60% of one gait cycle and swing makes up the remaining 40%. [3] The lower limbs are only in contact with the ground during the stance phase, which is typically subdivided into 5 events: heel contact, foot flat, mid-stance, heel off, and toe off.
Walk cycle with arm swing. Arm swing in human bipedal walking is a natural motion wherein each arm swings with the motion of the opposing leg. Swinging arms in an opposing direction with respect to the lower limb reduces the angular momentum of the body, balancing the rotational motion produced during walking.

A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body, it is called the midsagittal or median plane. If it divides the body into unequal right and left sides, it is called a parasagittal plane, or less commonly a longitudinal ...
The Oxford English Dictionary indicates that sagittal in the sense of the sagittal suture along the vertex of the skull pre-dates other anatomical usage. [7] Sagittal axis or anterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes
These terms come from Latin words with similar meanings, ab-being the Latin prefix indicating ' away ', ad-indicating ' toward ', and ducere meaning ' to draw or pull '. [ b ] Abduction is a motion that pulls a structure or part away from the midline of the body, carried out by one or more abductor muscles.
It is also known as the plane of communication. The third plane is the combination of the vertical and the sagittal dimensions and is called the sagittal, or wheel plane. It is also called the plane of operations. [8] The Diameters are the lines that connect the opposite corners of the planes. Each plane has 2 diameters, crossing in the middle.
