How do assistive devices assist physical therapy patients?

The correct answer is B, as assistive devices are specifically designed to help individuals with functional limitations improve their mobility and independence. These devices range from simple tools, such as canes and walkers, to more complex equipment, like wheelchairs and prosthetics. By enabling patients to move more easily and safely, assistive devices play a crucial role in the rehabilitation process, allowing them to perform daily activities with greater ease and confidence. This support is vital for enhancing their overall quality of life and promoting self-sufficiency in various environments.

While the other options mention aspects of patient care and rehabilitation, they do not accurately describe the primary function of assistive devices. For example, while enhancing therapeutic exercises is important, it is not the main purpose of assistive devices. Similarly, providing entertainment or monitoring vital signs does not align with the core use of these tools in aiding movement and independence during therapy sessions.
