The concepts of Envelope of Function and Physical Stress Theory are very useful in rehabilitation applications. We review these constructs and give ideas for use in the clinic.

Our understanding of the ACL, it's related pathophysiology, surgical strategies, and postoperative rehabilitation has an interesting history. We take a tour of the history and interview a couple guests who lived it.

So we're not the best with chronic nonspecific low back pain. We also tend to underload our patients in general. Maybe if we increased the intensity of our exercises, we would be more effective with chronic nonspecific low back pain. Well, at least we can test it!

Clinical depression is a very real part of many of our patients' lives. As a matter of fact, our current understanding of many commonly treated PT diagnoses suggests that clinical depression may be a huge driver of symptoms. How do we identify it in our patients? Assuming we can do that, what do we do about it once we identify it?

One of the most important components of ethical healthcare is patient education. A fully informed patient makes everything easier later during the care. But that includes educated on the good and the bad. Sometimes "being hopeful" can actually be a disservice.
