What to Expect – The POSI Process

Initial Evaluation

Subjective and objective prosthetic evaluation performed each time a patient is in need of a new prosthesis or socket replacement. A thorough evaluation is an essential first step in choosing the most appropriate plan of orthotics and prosthetics management to meet your needs and achieve your goals.

Before the physical evaluation begins, we ask very important questions about your hobbies, vocation, daily activities, family life, associated health concerns, and your living environment. Physical evaluation will then be conducted consisting of limb shape and condition, general muscle strength and flexibility, and gait mechanics. At the time of your evaluation, we will discuss your aspirations and goals, as well as your time frame to accomplish them. We will talk about what barriers you see that may impact the realization of your goals and a plan to mitigate those barriers.

Hand Cast

The first step in making the prosthesis is obtaining an impression of the residual limb. Impressions of the residual limb will be captured by hand casting with plaster. The cast will be filled with plaster to make a model of the limb. Model will then be modified to obtain appropriate weight bearing characteristics and shape to fit the needs of the patient.

Multiple diagnostic fittings

Diagnostic test sockets (DTS) are clear plastic sockets used to check fit and mock up alignment of components. Sockets should contact limb in all areas, have no visible gapping, be comfortable, and offer control through gait cycle or range of motion. At this stage definitive componentry will be set up and aligned both statically and dynamically. The DTS allows us to continually fine tune fit throughout the alignment process. After all adjustments have been made to the DTS socket, fit and alignment will be captured and transferred to a definitive socket.

Delivery of Prosthesis

Prosthesis will be completed with all definitive materials and componentry. Fit and alignment will be verified and necessary adjustments will be made. At this point we will refer you to a therapist for formal gait training. Even though the prosthesis is in its definitive state, we will continue to monitor your progress through frequent follow- up care.

Coordinated Rehab Process

Our practitioners will assist you to coordinate your complete orthotics and prosthetics rehab experience. This includes follow-up throughout the rehab process, often in person at the rehab facility. Additionally, we will advise you on how to find the correct therapist to meet your needs. We will help you to find any referrals and supports you may need throughout the process to help you achieve your goals.
We realize goals and aspirations may change or evolve as your confidence improves. In addition, your body and residual limb will continue to have changes. We will manage you through those changes, until it become necessary to replace sockets or components. At this time the orhtotics and prosthetics evaluation process repeats itself.
