What is one of the main benefits of using a liner with a lock or lanyard?

• A. Eliminates the need for hygiene
• B. Reduces swelling in the limb
• C. Increased range of motion
• D. Improved weight distribution

Answer: (C)

Using a liner with a lock or lanyard primarily enhances the fit and stability of the prosthetic device, which can greatly contribute to an increased range of motion. This design allows for more secure attachment between the residual limb and the prosthetic socket, which can facilitate movement and prevent shifting during activities. A secure fit ensures that the prosthesis works in harmony with the user's natural biomechanics, leading to improved mobility and confidence during movement. The other options, while they may have some merit in different contexts, do not directly relate to the primary advantages offered by a liner with a lock or lanyard. For instance, while proper hygiene practices are essential in prosthetic care, the liner with a lock or lanyard does not eliminate the need for hygiene. Similarly, while swelling management is important, the primary function of these components is not directly related to reducing swelling. Presenting an improved weight distribution can often be a result of the overall design of the prosthesis, but it is not the primary benefit specifically attributed to the use of a liner with a locking mechanism or lanyard.
