At its core, a joystick controller operates by translating the user's movements into signals that control the wheelchair's direction and speed. Historically, these controllers were relatively simplistic, often resembling the joystick found in gaming consoles. However, as technology progressed, so did the sophistication of these controllers. Modern joystick controllers often incorporate features like proportional control, allowing for more nuanced responses based on the degree of joystick movement. This means that the further the joystick is pushed, the faster the wheelchair moves, giving users greater control over their speed and direction.

2. Walkers Walkers are more substantial than canes, offering additional support. They come in different designs, including standard walkers, wheeled walkers, and rollators. Standard walkers require lifting to move, which can be challenging for some users, while wheeled walkers and rollators allow for smoother movement. They often feature hand brakes and seats, making them versatile for resting while on the go.
