Your Guide to the Most Common Physical Therapy Abbreviations

No matter what setting you work in, you likely encounter physical therapy abbreviations on a regular basis—but it's not always easy to keep them all straight, and new ones are seemingly created every day. Yet in an environment where clear communication is essential, a misunderstood abbreviation could be dangerous.

With that in mind, here's a list of some of the more common cross-setting physical therapy abbreviations. There will never be a truly exhaustive list, and your own setting likely has its own unique shorthand, but this collection should give you a strong foundation.

We also have created a list of common OT abbreviations here.

Don't Forget to Confirm, Confirm, Confirm!

Across physical therapy, abbreviations are understandably popular for saving time—but they don't come without a risk. For example, as you can see in the list above, some medical abbreviations (such as BOS) have multiple meanings, which can muddle clarity.

We hope this article helps you navigate abbreviations better and lower the risk of misunderstanding, but remember that whenever in doubt, confirming meaning via in-person communication is still essential for patient safety.
