For whom is the TF MAS socket principle indicated?

The TF MAS socket principle is particularly indicated for patients requiring less voluntary control because it is designed to provide a more forgiving and accommodating fit. This type of socket allows for greater pelvic stability and control without demanding excessive muscle activity from the user. It is beneficial for individuals who may have difficulty managing more active or restrictive prosthetic designs, thus enabling them to engage in daily activities more comfortably.

In contrast, the other options are less appropriate for the TF MAS socket principle. While individuals with high physical activity levels typically benefit from more advanced suspension systems that offer more dynamic range and control, this specific socket design may not provide the necessary responsiveness required in high-energy situations. Additionally, those with long residual limbs may have different socket design considerations focusing on support and alignment rather than the MAS principles. Lastly, the TF MAS socket is not limited to unilateral amputees; it can also be used for bilateral cases, making the inclusion of unilateral criteria too restrictive for its application.
