Why Rehab Innovation Needs Real-Time Feedback with Brent Pekarski and Ankit Shah

Rehab Innovation with Real-Time Feedback

Physical therapy outcomes depend heavily on what patients do between appointments, yet that is often where clinicians have the least visibility.

Rehabilitation is not limited to the clinic. For many patients, the real work happens at home: repeating exercises, rebuilding strength, restoring range of motion, and relearning proper movement patterns. But the current model often relies on a fragile handoff. A patient receives instructions, maybe a video, maybe a printed home exercise program, and then returns days later to report how it went.

That leaves physical therapists working with limited information. Did the patient complete the exercises? Were they done correctly? Did pain interfere? Did the patient compensate with the wrong muscle group? Did they move too fast, rotate improperly, or unknowingly reinforce a poor pattern?

For rehabilitation to become more effective, care needs to extend beyond the appointment itself. That is where real-time feedback, wearable sensors, and better movement data could meaningfully change the patient and clinician experience.

The home exercise gap is a clinical blind spot

Home exercise programs are essential to physical therapy, but they are difficult to monitor. Even a highly engaged patient may misunderstand an exercise, forget key instructions, or perform a movement differently at home than they did in the clinic.

For clinicians, that creates a major gap. Progress is often evaluated through patient self-reporting, observation during the next visit, and the therapist’s best interpretation of what happened in between.

As Brent Pekarski put it, “There’s very little insight that we are given as far as physical therapists outside of maybe them doing the honor system.”

That matters because missed or incorrect home exercises can change the entire course of care. If a patient is not improving, the therapist may assume the plan is ineffective and adjust treatment, when the real issue may be that the patient was not able to complete the program correctly or consistently.

Better visibility could help clinicians separate a plan problem from an execution problem.

Real-time feedback can help patients move correctly

Movement quality matters. In physical therapy, it is not enough for a patient to simply perform repetitions. The way they move can determine whether they build strength, restore function, compensate poorly, or reinforce the wrong pattern.

This is especially important because humans adapt to what they repeatedly practice.

As Ankit Shah explained, “If you teach wrong movements, you’re gonna learn wrong movements. If you teach right movements, you will learn right movements.”

Wearable sensors that track three-dimensional motion can help close that gap by providing feedback while the patient is moving. Instead of waiting until the next clinic visit to discover that an exercise was performed incorrectly, patients can be corrected in the moment through visual, audio, or haptic cues.

That kind of immediate correction could be especially valuable for orthopedic rehabilitation, sports recovery, neurological rehabilitation, and any care pathway where movement quality affects outcomes.

Better data can make clinic visits more useful

The goal of rehabilitation technology should not be to replace the physical therapist. The stronger opportunity is to make the therapist’s time more valuable.

When clinicians can see whether patients completed exercises, how they moved, what range of motion they achieved, and whether pain was reported, appointments can become more targeted. Instead of spending the first portion of a visit reconstructing the previous week, the therapist can begin with objective information.

That changes the conversation from “What happened?” to “Here is what the data shows. Let’s build from there.”

It also helps reduce guesswork. If a patient is struggling, the clinician can identify whether the issue is compliance, pain, range of motion, incorrect form, or a need to modify the plan.

As Brent said, “Now my session’s more valuable.”

Workflow is the difference between useful and unusable

In healthcare, even a promising technology can fail if it disrupts the clinical workflow. A tool that adds too much documentation, creates extra steps, or does not fit naturally into how clinicians already deliver care will struggle to gain adoption.

That is why rehabilitation innovation has to be built with a deep understanding of the clinical environment. The technology must fit into scheduling, evaluation, home exercise assignment, documentation, follow-up, billing, and patient communication.

For founders, the lesson is clear: clinical workflow is not a later-stage implementation detail. It is part of the product.

Why this matters

Physical therapy is facing a growing set of pressures: clinician shortages, patient dropout, limited appointment availability, access barriers, and rising demand for care that supports longer, healthier, more active lives.

At the same time, patients are becoming more comfortable using technology to understand their bodies. Wearables have already trained people to care about steps, sleep, heart rate, recovery, and performance. Movement quality may be one of the next major frontiers.

If rehabilitation technology can help patients move correctly at home, help clinicians see what is happening between visits, and generate better data across populations, it could improve both outcomes and efficiency.

What to watch

The biggest opportunity may be the evolution from individual exercise tracking to broader movement intelligence.

If enough structured movement data can be collected across patients with similar diagnoses, clinicians may eventually be able to identify which exercises, progressions, and interventions produce the best outcomes for specific conditions. That could make rehabilitation more measurable, personalized, and evidence-informed.

For startups, the practical implication is simple: build around real clinical problems, not just technical possibilities. The most valuable tools will be the ones that help patients follow through, help clinicians make better decisions, and fit naturally into care delivery.

Rehab innovation is not only about getting people back to movement. It is about helping them move correctly, consistently, and with better support between visits.
