Category Selection Instructions

To optimize the selection and ensure amputee’s safety, follow the two steps below to

determine the appropriate category.

  1. Locate the column that corresponds with the amputee’s impact level.
  2. Within the selected column, locate the amputee’s weight.

Important Note: If the amputee has a long BK, carries heavy loads or will reach a higher impact level within a year, choose the next category higher.
Warning: Choosing a lower strength category than what is suggested based on the above procedure and patient data will void the warranty. If your patient’s weight exceeds the limits of the chart please call Trulife Customer Service.
