Final answer:
The Terminal Stance phase of gait starts when the opposite limb contacts the ground and ends just before the lifted foot leaves the ground, transitioning weight and momentum for walking.
Step-by-step explanation:
The phase of gait that begins when the opposite limb contacts the ground and ends just prior to lift off is termed the Terminal Stance. This phase follows mid-stance and is characterized by the body weight moving in front of the foot, preparing for the foot to leave the ground. It is an important part of the gait cycle that ensures efficient transfer of weight and momentum for the progression of movement. The other options provided, such as Loading Response, Pre-swing, and Mid-stance, represent different parts of the gait cycle, each with their own unique characteristics and timing during the walking process.
