Final answer:
The question deals with different types of walkers: Standard Walker, Rolling Walker, and Reciprocal Walker, which are mobility aids, and the 3 point (NWB) gait pattern used for non-weight bearing assistance.
Step-by-step explanation:
The question presented refers to different types of walkers, which are mobility aids used by individuals with difficulty walking due to illness, injury, or disability. The Standard Walker is a simple, frame-based walker that requires the user to lift it and place it forward before stepping into it. It is primarily used by those with ample upper body strength but poor balance. The Rolling Walker, also known as a rollator, typically features wheels on the bottom and may come with a seat and hand brakes, allowing for smoother movement and less physical strain as it does not need to be lifted. The Reciprocal Walker allows each side to move alternately, giving a more natural walking rhythm and can be especially helpful for those who have partial weight-bearing capacity. When mentioning '3 point (NWB)', it usually refers to a three-point gait pattern used with crutches or a walker, where 'NWB' stands for non-weight bearing on one limb.
