What is a main advantage of using a Cushion liner in prosthetics?

The use of a cushion liner in prosthetics primarily enhances the suspension of the prosthetic limb during the swing phase of gait. This increased suspension is crucial because it helps to secure the prosthesis more comfortably and effectively against the residual limb, reducing the likelihood of movement that could lead to discomfort or instability. A well-suspended prosthesis allows for a more natural gait, improving mobility and confidence for the user.

In contrast, options that suggest no rotational control or a universal fit do not reflect the intended functions of cushion liners. Cushion liners are designed with specific characteristics that cater to individual anatomy, so they are not universally fitting for all patients. Additionally, while cushion liners can be used for individuals with various activity levels, they do not specifically indicate that they are best suited for low activity levels alone, as active individuals can also benefit from their use.
