Which of the following is NOT a con of the seal-in liner?

The choice indicating that being perceived as heavier is not a con of the seal-in liner is accurate because the weight of the liner itself does not inherently limit its functionality or use. Seal-in liners are designed for comfort, fit, and improved suspension in prosthetic limbs; thus, their perceived weight does not typically result in negative implications for the user’s overall experience or performance.

In contrast, the other options suggest specific functional limitations. The necessity for good hygiene is critical with seal-in liners to prevent skin irritation or infection, as they maintain close contact with the skin. Standing to don the liner may be important for achieving the best fit or seal, which is a consideration during daily use. Finally, requiring good hand strength can impact a user’s ability to manipulate the components of the liner and prosthetic system effectively, which could hinder performance for those with limited dexterity. Therefore, while all the other options reflect challenges associated with the use of seal-in liners, the perception of weight does not serve as a substantial drawback.
