      First off, I really like the first Figure in the paper. I think it provides a nice glimpse of how this cascade occurs. This is a great article to follow-up with after hearing Eric’s neuroscience education talk our last course weekend.
      The paper states that hypersensitivity has been found in a variety of pain conditions including LBP, neck, TMJ, elbow and knee pain, tension-type headaches, and fibromyalgia. Who doesn’t see these patients on a daily basis?! Therefore whenever we suspect that sensitization processes are relevant components of the patient’s complaints, we may need to employ some of our skills in providing neuroscience education.

      Recently Eric and I have been discussing strategies to educate patients in a way they understand their symptoms or pain. This is an area I have come to realize through residency that I struggle with. As much as I love the education piece to our job, I do a pretty awful job at explaining items like postural correction, motor control, and reasons the patients are experiencing pain or symptoms as a result of their given movement patterns. So here are a couple things Eric has shared with me that he’s found success with (which now I’m finding success with) that not only provides the patient with a clearer understanding of their pain, but also utilizes patient sensitive descriptions to avoid driving fear and biopsychosocial issues. Here are just a few…

      • Rather than using terms like joint degeneration, wearing/breaking down, cartilage thinning, joint space narrowing, ect., try stating these things as simply “changes” as we age or get older. These “changes” can easily be related to the changes we see in the mirror like grey hair, increased wrinkles etc. Patients seem to easily understand this idea and it seems to sit better with them. Then I throw the joke, wine only gets better with age, ha.

      • Patients with disc pathology like annular tears; ask these patients if they’ve ever had an ankle sprain (which should almost be everyone). You can use this as a platform to discuss how the annulus is ligamentous just as the ligaments in the ankle. Say you’re walking through the woods and step on a twig, 99% of the time you’re able to move along without even noticing. Say you’ve now sprained your ankle 1 day prior and you’re walking along the woods and you step on that same twig. You’re now probably going to notice the twig and you’re ankle’s probably going to hurt, you may lose your balance, you may even have some increased swelling and inflammation, and you may want to rest more to unload your ankle..….well that’s exactly like when we “sprain” the disc in your back. Just as your pain improved in your ankle, you’re pain in your back can improve as well. (and I would only name drop disc pathology if the patient comes in having already been contaminated with their images or has been told about all the awful “normal changes” that have appeared on their images that probably have nothing to do with their pain anyways.

      And on a side note and somewhat relative to this discussion, just yesterday I listened to a podcast from the Cleveland Clinic Health Talks. The title of the talk was; Pain Management of the Hip and Knee. This was a 19 minute talk given by Dr. Shrif Costandi one of the pain management staff at the Cleveland Clinic who has a special interest in Management of Chronic Pain. The talk began to specifically discuss management of osteoarthritis. He goes in to discuss how you can manage OA by prevention and treatment; treatment being that of conservative care and surgical. However this was where I kind of got mad because he reports conservative management as being that of medications and injections; specifically stating if your pain is not controlled with medications, the next step is injections. REALLY?! Not once in the 19 minutes did he mention the use of physical therapy as a conservative treatment option to manage pain from chronic osteoarthritis. So take away from this talk- manage pain with drugs. Maybe that’s what’s wrong with our current healthcare model. How about try moving which a million papers have provided strong evidence to suggest increased movement and activity in this population can decrease pain and stiffness. So just wanted to share and see what others may think.

      Awesome suggestions, thanks for sharing! I am definitely an over-educator and have been trying to focus more on just the tip of the iceberg to share with my patients lately. It’s easy to forget not everyone has the same educational background and when you are thinking you are helping with giving them information, they may only be retaining bits and pieces and sometimes, those bits can be construed into something completely different than what you intended. I am learning, less is more.

      For patients whom I suspect have some central hypersensitivity, I have found it helpful to explain to them that when you are in pain, your brain changes and starts to interpret touch that is not harmful as painful (easily proven by gently touching their leg, for example and helping them make the connection that touch from their finger gently on the skin does no damage, however, for some reason, they still feel pain). I think patients appreciate when we acknowledge that there are actual changes in their brain that they can’t control, versus them making it up or being crazy (I find that a lot of patients that have dealt with many doctors or unsupportive family members suffer from this fear). Once they understand that the brain has made some changes, I then tell them it is their job to help retrain the brain and help reteach it what is painful/harmful and what isn’t again. If they can understand that the brain is faulty at interpreting pain, and not that they are actually hurting themselves, then they are more willing to work through some pain in an attempt to help play an active role in “reteaching” it. This hasn’t been enough for everyone, but it has helped me get over the hump of willing to participate despite some pain with some patients.

      Hey Casey- I really like that idea. I was just telling Michelle at lunch that I had a 27 yo. female patient in this morning who’s a grad student at UVA. She has complaints of neck pain with cervicogenic headaches (I see a lot of these patients secondary to poor postural habits with academics). However while I was working with her this morning she told me her R. shoulder had been hurting and then her R. ankle had started hurting when she went on a short walk. Per her subjective hx, she is a healthy young lady with no previous orthopedic hx or co-morbidities. Therefore I definitely think she may be demonstrating some central sensitization as she’s explained her neck has been bothering her for some time. So I definitely used the ankle/twig story this morning, haha. But I really like the idea of actually touching her leg with some gentle pressure to see how she responds. I think that will be another great platform to educate her on how the brain is changing and possibly perceiving non-noxious stimuli as threatening. Nice suggestion Casey. I’ll keep you posted how it goes. Spring Break is next week so it may be in 2 weeks, ha.

      Stephanie and Casey- I enjoy hearing your process with patients and how to educate the patient on the change in pain threshold and the change in the neuromatrix of the patient’s brain. It is very difficult and you have to make sure you are putting your words in the right context when you say “it’s all in your head”. From Eric’s lecture and from listening to Louie Puentedura, using video or images (“Why I hurt” cards) have helped quite a bit, especially with individuals returning to a work setting and have a high FABQ. As well, Aaron and I have gone as far as allowing the patient to watch the Lorimer Moseley TED talk (in side lying) while doing Elveys for lumbar spine. The neat thing about this patient population is that you can be creative and tap into your non-ortho skills. From the article, I think this is a good start to quantify a person’s pain response. I do see the ultimate limitation that pain is an output and there are a million and one variations of how pain is generated and then processed as an output from each person. As well, the population measured in this article is those with chronic pain but I wonder how different those with simply a “revved up” nervous system would vary.

      I think that PT is a backburner for the medical world. To have such a high researched hospital not mention a thing about PT is nuts. We have done nothing but keep people away from the knife and improve quality of life. That is very frustrating to hear but the only want to improve this is keep doing research, and finally treat some of these docs for their injuries and make them believers

      As for the article,I like the NWR as this seems to maybe help differentiate how the pain is being sent and which area is being affected
      I liked the idea of temporal summation never thought about this and maybe explaining this to patients that you are not changing intensity (could be why after walking a while the pain gets worse when its the same forces and rate)

      I showed the Why I hurt video to a patient the other day and she came back with a great point (she is a teacher) She said it was a great 14 min speech, but he never gave one solution or something a patient can do. And of course that is where we come in, but it makes a good point…. education is key and it will help a ton in the long run to get to the source and figure out the problem …. but we need to have a solid foundation of WHAT WE ARE GOING TO DO TO HELP THEM FIX IT!
      I would love some great advice of the next step after we give these great explanations that everyone is working on Its hard to get someone to believe it is nervous system and only exercise will help Thanks for the help

      For me. I love using laymen terms and breaking it down nice and easy. My problem is that I sometimes get so basic that can make me sound almost uneducated and not very reliable.

      Hey guys,
      Sorry to jump on the bandwagon late on this one. Great article on central hypersensitivity and something that we may not think of initially when our patients complain of pain. I have one patient in particular that I think of with this topic. He’s an active college student that has been coming to the clinic since November for bilateral shoulder pain. He presents with significant bilateral shoulder instability and secondary impingement as well as scapular dyskinesia. He has been treated by three different therapists with minimal symptom relief. Pt. had exploratory arthroscopic surgery two months ago and the surgeon found nothing structurally wrong with shoulder. He reports no symptom relief following surgery and continues to have subjective reports of significant pain with even the most basic exercises and activities. His orthopod also prescribed him an anti-inflammatory. After reading this article and the posts, I stole one of Eric’s analogies (thanks Steph!) and had a conversation about his symptoms last week. Kyle—great suggestion about using the “Why I Hurt Video” –that might be something beneficial for my patient to watch as well.

      sounds like an anti anxiety may help this dude too. I am surprised that after the surgery showing nothing that he didn’t realize it was ok. Does he have some type of conversion disorder?
      you have your hands full. I hope you get through his shell and turn the leaf for him!
