The ground reaction force vector represents the sum of all forces acting between a physical object and its supporting surface. Analysis of the center of pressure is common in studies on human postural control and gait. It is thought that changes in motor control may be reflected in changes in the center of pressure. In biomechanical studies ...
Cutaneous reflexes demonstrate variations in the muscles activated and the timing at which they are activated depending on which portion of the gait cycle the stimulation occurs. This variation suggests a functional role for the reflex to provide us with a smooth gait alteration when encountering or anticipating obstacles and challenging terrain.
Humans are capable of walking at speeds faster than 2.0 m/s, and capable of running at speeds slower than 2.0 m/s. As humans can walk or run at the same pace, researchers have attempted to explain why humans choose the transition speed that they do.
The gait analysis is modulated or modified by many factors, and changes in the normal gait pattern can be transient or permanent. The factors can be of various types: Extrinsic: such as terrain, footwear, clothing, cargo; Intrinsic: sex, weight, height, age, etc. Physical: such as weight, height, physique; Psychological: personality type, emotions
Besides, children of different genders will have different rates of gait development. Significant developmental changes in gait parameters such as stride time, swing time, and cadence occur in a child's gait two months after the onset of independent walking, possibly due to an increase in postural control at this point of development.

The Lokomat, AutoAmbulator, and the Mechanized Gait Trainer were all made to function with a treadmill. Wearable gait trainers would be useful to travel over ground. This adds the complications involved with starting and stopping a stride, changing direction, going up and down hills, and creating more challenging balancing exercises.
These leg mechanisms have applications in mobile robotics and in gait analysis. [3] [4] The central 'crank' link moves in circles as it is actuated by a rotary actuator such as an electric motor. All other links and pin joints are unactuated and move because of the motion imparted by the crank.
Gait training or gait rehabilitation is the act of learning how to walk, either as a child, or, more frequently, after sustaining an injury or disability.Normal human gait is a complex process, which happens due to co-ordinated movements of the whole of the body, requiring the whole of Central Nervous System - the brain and spinal cord, to function properly.
