This Is What PT and Prosthetist Collaboration Can Look Like

During the Amputee Rehabilitation Specialist Certification Course in Chicago, we had a patient model come in for the gait and prosthetic training portion of the lab. About ten minutes in, everyone in the room started noticing the same thing.

Every time she shifted her weight over the prosthetic side, the prosthesis was dropping laterally. She was an above-knee amputee, and once we saw it, it was hard to miss. We kept working and trying to progress through the activities, but it became impossible to ignore. Some of the interventions we wanted to walk through with her just weren't realistic because she was fighting the prosthesis the entire time.

After watching her move for a while, it seemed like a combination of things. She was losing socket fit, the alignment probably needed to change, and there was likely a muscular engagement piece as well. Her limb volume had decreased as she became more active and started wearing the prosthesis more consistently. At the same time, she'd moved from a wider base of support toward a narrower and more efficient gait pattern, so the alignment that worked before may not have been working as well anymore.

That's pretty common early in the process. The prosthetist is trying to fit and align a person who's actively changing, which means the target is moving. In a lot of ways, those changes are a good sign. They usually mean the patient is progressing.

This is where the story gets good.

One of the PTs attending the course had worked with her in the past and knew her prosthetist. Right there during the course, she picked up the phone and helped get her scheduled for an appointment two days later.

Before the patient left, I told her to have her prosthetist call me during the appointment so I could explain directly what we were seeing. We ended up talking during the appointment, and I was able to describe what I observed, when it was happening, and what I thought might be contributing to it.

He tightened up the socket, made some alignment changes, and sent me a picture afterward. The improvement was significant.

Two days from identifying the problem to having it addressed.

I've said before how fortunate I was to work in the same clinic as my prosthetists. That kind of setup makes collaboration a lot easier. This situation had none of that. Different city, not a current patient of anyone in the room, identified mid-course during a lab. It still got addressed in two days because one therapist took the initiative to make the call and get the appointment scheduled, and the prosthetist was ready and willing to help.

If that information had only been relayed through the patient, important details likely would've been lost and the appointment may have been delayed. The patient knew something felt wrong, but socket fit, alignment, lateral instability, and gait mechanics aren't easy to describe when that isn't your language.

As clinicians, we can observe what's happening, describe it clearly, and communicate it in a way the prosthetist can immediately act on. In this case, he heard exactly what we were seeing, made the appropriate changes, and his patient moved better because of it.

The takeaway isn't complicated: when PTs and prosthetists actually talk to each other, problems get solved faster. This didn't require a shared clinic, a formal referral process, or perfect circumstances. It required one therapist to take initiative, one prosthetist willing to respond, and a direct conversation that helped the patient move better two days later.
