#46 Introduction to Assistive Devices for Mobility | Mechanics of Human Movement

Welcome to 'Mechanics of Human Movement' course !

This lecture provides an overview of assistive devices for mobility, with a focus on prostheses and orthoses:
Types of Assistive Devices: Discuss various assistive devices used for walking, including crutches, walkers, prostheses, orthoses, and exoskeletons.
Prostheses, Orthoses, and Exoskeletons: Define:
Prosthesis: A device that replaces a missing limb.
Orthosis: A supportive device that assists a limb with existing function.
Exoskeleton: A wearable robotic system that provides external support and assistance.
Active vs. Passive Devices: Differentiate between active devices, which utilize external power sources (e.g., batteries and motors), and passive devices, which rely on human body movements for actuation.
Challenges in Prosthetic Design: Discuss the complexities in designing prostheses, particularly those replacing limbs with complex articulation like the hand and foot.
Components of a Prosthesis: Describe the various components of a typical prosthesis, including the socket, liner, pylon, connectors, and prosthetic foot. Emphasize the importance of socket fit for user comfort and functionality.
Prosthetic Foot Design Considerations: Highlight the challenge of replicating the complex functionality of the human foot in a prosthetic design. Introduce the Solid Ankle Cushioned Heel (SACH) foot as the simplest type of prosthetic foot.
