What prosthetic feature can help accommodate a patient’s varying activity levels throughout the day?

A dynamic response heel is designed to accommodate varying activity levels by providing energy return during walking and transitioning between different surfaces and inclines. This feature utilizes materials and structures that store energy during the stance phase of gait and release it during the push-off phase, enhancing the patient's mobility and efficiency. It allows for a more natural gait pattern and adapts well to different speed demands and terrain variations throughout the day.

The other options present valuable features but do not primarily focus on adjusting to varying activity levels over time. Adjustable foot resistance may provide some flexibility, but it typically does not offer the same level of energy return and adaptability as a dynamic response heel. A split housing design often emphasizes comfort and ease of use rather than direct activity adaptation. Weighted forearm support is important for stability and function but does not relate directly to accommodating changes in activity levels.
