What feature is typical of K1-K2 knee control?

• A. Fluid responsiveness
• B. Single-speed operation
• C. Microprocessor control
• D. Variable cadence

Answer: (B)

The characteristic that is typical of K1-K2 knee control is single-speed operation. Individuals classified at these levels typically have lower functional mobility demands. As such, their prosthetic knees are designed for straightforward functionality without requiring complex adjustments or responsiveness to varying speeds or terrains. Single-speed operation means that the knee joint can be set to a fixed speed of movement during the gait cycle, which suits the limited activities that K1 and K2 users generally engage in, such as walking on flat surfaces or performing basic transfers. In contrast, more advanced features like fluid responsiveness, microprocessor control, and variable cadence are associated with higher classifications (K3 and above), where users require knees that adapt to different speeds, terrains, and activities, allowing for more dynamic movement and functionality.
