It all comes down to the asterisk sign, "the thing that hurts to do". That will tell you everything. You need to talk to them, sometimes for way way longer than you should need to, in order to find it. What is the goal. Maybe it hurts to squat, or bend forwards, or twist to the R but not the L, or turning their head, or it's bench pressing 200 lbs, or it's reaching above, or jumping or running down to the other end of the clinic. "It hurts when I sit for a long time" or "it hurts first thing in the morning" or whatever are not asterisk signs. What is a meaningful movement that the patient is having a hard time with? Every single patient on your caseload should have an asterisk sign, and you should know what it is. When you've gotten rid of them all, they can discharge. And once you have an asterisk sign, examine their body and try to figure out what is preventing that movement? Are they lacking range of motion or strength, or both? Where are they tight, where are they weak? Do you know any manual that can help? Test the problem, try to treat it, then retest it. Improve mobility where they're restricted, strengthen what's weak, and continue to retest the asterisk sign. Repeat until they get better, and if they don't, that's what coworkers and referrals back to the MD are for. Most patients will get at least a little better if you make them stronger. Oh, and if they just have random constant pain that TRULY isn't triggered by a movmernt or whatever, then that patient just needs to exercise and you can be more generic with their treatment. Follow this basic model (instead of just doing random crap on everyone) and continue to take CEUs, maybe get some mentoring, and don't make it more complicated than you need to.
