PhysioFuturism: How Technology is Changing the Future of Physical Therapy

The number of Americans suffering from a chronic disease is skyrocketing – in 2016, one out of every five Americans had chronic pain, which means that the demand for physical therapy is on the rise. This, in addition to the aging population, means we need the capacity to care for more people with musculoskeletal problems, so they do not resort to higher risk and higher cost treatments like surgery and opioids when they are not required.

As physical therapists, we have the skills to help, now we need to find ways to make sure that all these people are getting the help that they need.

One way to deal with this issue is through job creation. In 2014, the Bureau of Labor Statistics predicted that 71,800 new physical therapy jobs will be created by 2024.

However, less than one out of every ten people, who could benefit from physical therapy, received physical therapy treatment. Why is that? While we don’t know for certain, we believe a few of the main reasons are awareness, accessibility, and affordability.

Perhaps technology can allow existing physical therapists to treat more patients. This can be achieved through harnessing technology through automation of repetitive tasks such as the measurement and logging of patient movement. By creating more time, clinicians have either extra time to spend educating their patients and treating them or have time to treat more patients. The aim of this is to improve clinic efficiency and allow existing physical therapists to better help current patients and to treat more patients.

Technology can also be used to spread awareness, generate excitement about seeking musculoskeletal care, and enable new business models catering to the nine out of ten non-consumers of physical therapy.

This may sound very far in the future, but technology like this already exists.

Computer vision is when a camera can recognize objects such as people in their frame of view. While this may sound simple, this step-in technology is completely changing the assessment process for our profession.

Imagine having your patient stand in front of a camera, which instantly recognizes and locks onto each joint and measures all their joint angles as they move. With no markers, no attachments, your patient just has to perform your prescribed movements. Instant motion capture with zero set-up time.

Now imagine that this data is instantly compared with normative movement data and issues in specific body areas are instantly flagged to the clinician.

Markerless motion analysis is transforming patient flow in clinics across the country by automating the analysis of movement. It’s been proven to be more accurate than visual assessment and it’s quicker because multiple body joints can be dynamically assessed at once. Pretty cool, right?

Why Now?

Historically, academic biomechanics labs and Hollywood adopted multi-camera, marker-based systems, which are the gold standard of accuracy. However, operational complexity meant that mocap was largely impractical in the clinical setting. Recent advances in computer vision, as well as hardware, have made markerless systems accessible to the clinic, enabling practical (or as we say, clinical) motion analysis.

How it Works

Many motion analysis systems use a standard color image camera, just like your cell phone’s camera. 3D motion analysis systems use depth-sensing components (e.g. infrared depth sensors and wearables). Computer vision algorithms allow for the elimination of wearables and markers. These algorithms are trained to recognize the shape of the human, and the person’s body joints.

Clinical markerless motion analysis products eliminate the need to post-process motion capture data. This saves physical therapists sweet precious time and allows for more time to help more patients.

You, my friend, are irreplaceable.

I know this article may be setting off alarm bells for some of you, mostly regarding being replaced by robots. But the great news is that physical therapy is not the kind of profession that can be fully automated. Physical therapy is a highly specialized, manual, and a human-centered profession. So do not fear, physical therapy is unlikely to be replaced but you can harness technology to make your clinic more efficient on an operations level. By automating repetitive, lower-level tasks, we can focus on our skills that can never be automated: empathy, perception, and manual therapy.

Are you ready to use technology to your clinic’s advantage? PhysioFuturism is now!
