Which of the following solutions can be implemented if the TD opens too late during elbow flexion?

When addressing the issue of the terminal device (TD) opening too late during elbow flexion, it's important to evaluate strategies that enhance the coordination between elbow movement and TD function.

Shortening the forearm section can be beneficial as it reduces the distance that the elbow must travel before the TD begins to function. This can help synchronize the movements better and allow for a more immediate response from the TD as the elbow flexes.

Lightening the TD is another viable option. A lighter terminal device requires less effort to activate, which can make it more responsive and reduce the delay experienced when trying to open it. This is particularly helpful for individuals who may have reduced muscular strength or control.

Adding a forearm lift assist can also be effective as it aids in elevating the forearm during the flexion movement. This assistance can facilitate a quicker engagement of the TD, making it open sooner in relation to elbow flexion.

Implementing any one of these solutions can improve the timing of the TD's opening, but selecting all of them can provide a comprehensive approach to more effectively coordinate the opening of the terminal device with the flexion of the elbow. Each method addresses different aspects of the issue, making the combination of solutions particularly beneficial.
