Which component would you recommend for a patient with no volitional strength of the thumb?

Recommending a thumb post for a patient with no volitional strength of the thumb is beneficial because this component is specifically designed to provide support and stabilization to the thumb without requiring active muscle contraction. A thumb post functions to keep the thumb in a functional position, allowing for better grasp function and improving the overall hand function by facilitating pinch and grip actions.

By using a thumb post, the patient can maintain the thumb in an optimal position for grip despite the lack of strength. This component helps in positioning the thumb effectively, which is crucial for enhancing overall dexterity and functional use of the hand. It can also alleviate any potential deformities resulting from a lack of strength, promoting better alignment and potentially reducing discomfort.

In contrast, while wrist supports and forearm straps offer general support to the wrist and forearm, they do not specifically address the needs of the thumb. A palmar bar can provide support for the palm and fingers but does not provide the targeted stabilization and positioning required for the thumb to function effectively. Thus, the thumb post stands out as the optimal choice for the patient's condition, focusing specifically on the thumb's support.
