Cognitive Behavioral Therapy for Chronic Pain

I attended a seminar on Cognitive Behavioral Therapy (CBT) for Chronic Pain. It was extremely enlightening and helpful in understanding additional methods to increase quality of life with chronic pain. I have been seeing more articles and information about mental health being included in the management for chronic pain but haven't had the opportunity to yet to complete a deep dive on all the information I've found. This idea of how mental health can affect chronic pain was more unfamiliar to me than I would have guessed, and it wasn't until I attended this seminar that the brief amounts of information I had been reading, finally made sense to me. I actually didn't realize either that there are CBT protocols for specific issues including pain and even insomnia. 

CBT is a therapy method that I believe whole-heartedly in for a variety of areas in life from improving mental health to even helping raise children and train pets. The premise and tools of CBT are that versatile. And when I combined the understanding I gained from this chronic pain seminar with my new knowledge of how the brain works to develop everything from how we interpret interactions, emotions, moods, to our core beliefs about ourselves and the world...holy cow, did CBT for chronic pain make even more sense. 

CBT for Chronic Pain (CBT-CP) has been researched for over two decades with strong evidence for its ability to improve quality of life. Unfortunately, not a lot of medical providers are aware of this, so they don't refer their chronic pain patients to mental health counseling. But that doesn't mean a chronic pain patient is out of luck. The manual for CBT-CP is available online, at no cost, so any qualified mental health professional can access and implement it into their therapy practice. And since it's free online, anyone who wants to implement the practices into their own lives can do so too. 

The protocol is spread across 12 sessions, although this can be lengthened as indicated. The basis of CBT-CP is that there is a connection not only between thoughts, behavior, and emotions but also with chronic pain. We know that in the cognitive triad of thoughts, behavior, and emotions there can be a cycle established that reinforces each of these aspects. For example, I'm sad so I decrease my activity participation, I then feel isolated, and I start to develop depression, my depression tells me to isolate more, this makes me feel sadder and lonelier, I then feel more depressed and hopeless, etc. Introduce chronic pain into this cycle and it also becomes reinforced while reinforcing the other aspects. For example, I hurt so I'm not going to do this activity, that makes me sad, and I feel more isolated from others, I think others don't want to bother with me because I can't do this activity, I focus on my pain, that makes me more irritable and hopeless feeling, I start feeling more depressed, etc. 

CBT-CP focuses on identifying (with collaboration from the client's medical providers) an exercise and pacing routine followed by increasing cognitive coping skills. By targeting chronic pain indirectly by addressing one's thoughts, emotions, and behavior that affect pain, it will help make it easier for a person to do what they are wanting to do and thereby increase quality of life. It's important to understand that CBT-CP does not cure or fix pain nor is perfection the goal, it is a tool for increasing quality of life in the self-management of chronic pain.

This first part of exercise and pacing allows for increased activity without the pain flares we so often experience every time we start to feel better again. When I learned this, I also had an "a-ha" moment for a deeper understanding of why I had been seeing an emphasis on "pacing" in the chronic illness community for the last several of years. It was, again, a term or practice I didn't really understand and hadn't researched much. I simply did activities as I was able to, often to an extreme level, and then dealt with the consequences afterwards - whatever those might or might not be. And I didn't think about it or analyze my actions and my symptoms. But this idea of pacing would be something that I would start to have more familiarity with following my gallbladder removal as I would find myself restricted to one day of increased activity without a pain flare that would last 3 days. And to help get past the one-day limit, I finally gave into attending physical therapy. But it was during this year that I would unknowingly be playing around with the concept of pacing. 

A common cycle for chronic pain patients is: I hurt so I restrict my activity and rest during my pain flare, once my pain flare subsides, I'll engage in all the activities I can that I wanted to do before that I now feel well enough to do, but then I engaged into much for my body, and I have another pain flare requiring another rest period. However, these recovery periods become longer and longer over time and the longer the recovery period, the more deconditioning our bodies go through creating a vicious cycle of increased pain and decreased activity. 

To the cognitive coping skills part of CBT-CP, think about the 5,000-6,000 thoughts a day a person has on average. How many of those thoughts do you remember from yesterday? We have so many automatic thoughts that whip through our brain and a large number of those tend to be negative, discouraging thoughts that our brain keeps hearing and those thoughts can influence our emotions and our behavior. And when chronic pain is involved...we have even more negative thoughts. Have you noticed when you focus your thoughts on pain that you're having in the moment, that the pain tends to increase? 

Pain is a subjective experience that can only be quantitated by one's subjective view or rating of it up to a degree. This isn't to say at all that pain is just in our heads but that there is a difference in the body for measuring and identifying pain levels once pain starts to affect the nervous system. 

Pain is influenced not only by biological factors but also social and psychological factors. The way that we're treated by others can affect our pain level as well as how we treat ourselves psychologically and how our body responds. 

The body reacts to pain with autonomic endocrine, and immune responses that can increase pain and activate the sympathetic nervous system - the fight or flight mode. When the sympathetic nervous system is activated, it can be measured by heart rate, galvanic skin response, muscle contraction, and EMG procedure that shows muscle response to electrical activity. 

When I'm having to wait longer in a provider's lobby, I start to think about  how long I've been sitting there and how uncomfortable the chair is and then the next thing I know, my body is aching because I've been sitting in an uncomfortable chair for a long time without feeling able to move or walk around because the more I move, the more likely I'll have to go to the bathroom and if I have to go to the bathroom before I'm called back then I worry I'll get called while I'm in the bathroom and they'll think that I'm not there so my appointment will get overlooked or delayed even longer. So, I get into this cycle of spiraling anxious thoughts and a focus on how uncomfortable my body feels trapped in this chair for an unknown length of time. 

What can one do about this to help with chronic pain? 

The cognitive work in CBT-CP is vital as a preparation for implementing behavioral changes to address chronic pain, which in turn will address the emotions we develop as a response to pain and our health conditions. It is also important to obtain medical clearance from one's medical provider for behavioral changes to be implemented and worked on in conjunction with various medical modalities as indicated, such as neurology, pain management, or physical therapy.

An integral tool for assessing progress in CBT-CP is pain measurement tools such as SUDS - Subjective Units of Distress. This identifies where one is starting in their pain level and how it's affecting their quality of life. As the sessions continue, SUDS also identifies not only progress but also what is and isn't working for the individual. There are several different pain assessment models that can be used including ones specifically for children and nonverbal individuals. 

Once the current level of pain, its impact on quality of life, multidisciplinary collaboration and goals are established, it's time to start learning and implementing CBT itself. 

Part of that is realizing that chronic pain is not acute pain. Pain tells our body to activate the fight or flight mode as a proactive, protective response. Our body isn't able to distinguish between acute and chronic pain, we must learn how to instead. The fight flight mode is appropriate when experiencing acute pain but not chronic pain. This is because during acute pain, our body is telling us to stop or get out of the situation to protect itself, it is under threat and harm. This alarm tells us to not engage in activity out of fear of causing harm. Which can occur during acute pain with increased activity, whereas with chronic pain this is usually not the case. Therefore, due to the ongoing condition of chronic pain, the pain that one experiences no longer is a reliable warning that harm is occurring. Rather than withdrawing from activity in fear of causing harm with chronic pain, it is to our benefit to engage in activity with pacing practices in place. Movement not only helps with muscle recovery but also maintaining joint maneuverability and flexibility. When I was in physical therapy to correct the deconditioning that I experienced following my gallbladder removal, there were days that I had a pain flare following the initial sessions and with new exercises. On those days, my therapist explained the importance to continue engaging in movement so that my body would better recover and maintain progress through the pain flare. To do this, I was taught recovery exercises to complete during pain flares than my every day strengthening exercises. 

When we over engage in activity, our pain increases requiring longer and longer recovery periods each time as our body becomes more deconditioned during each recovery period. To break this cycle, we must engage in activity in regular intervals to recondition our bodies and reduce the chronic pain cycle of crashing and burning.

The intervals for regular activity of what a person can tolerate is extremely individualized and may require a trial-and-error approach to determine where someone's limits lie. Limits can be determined by starting with intervals of activity as small as needed. An important part of this is physical exercise to recondition the body to allow for greater activities as the sessions progress.

Identifying that one has pain when doing X activity for Y amount of time. This can be determined in two ways - 

1. I do activity until I start to feel pain and I know I need to start with a shorter time interval than that 2. I am able to do activity for this amount of time without pain, I will increase the time incrementally to determine what time interval I can tolerate.

Pacing comes into play by stopping the activity at the identified interval and allow for a recovery period. To further reduce deconditioning, pacing amounts can also be determined by pacing at 50% rather than 100%. The goal is to reach a steady pace of activity and rest to avoid pain flares, deconditioning, and increase quality of life.

Moderation is the key principle to pacing. This is a hard concept for many of us as we are used to over engaging in activity on our good days leading to us crashing and burning. We often think that it takes less time, and we can be more productive if we get everything done when we feel our best. In actuality though, this takes more time away from us and what we may be needing to do. Moderating our activity allows for more things to be done in total with less recovery periods required. 

For example, we can go full throttle for two days straight but then have a flare that requires a week recovery.  Or we could pace ourselves for the week at a certain percentage each day of activity and rest and not have a pain flare that requires an extended recovery period.

As we rebuild our bodies with exercises and engage in activities with pacing, we can monitor our ability to increase that activity time with incremental increases to the intervals between activity and rest. This is not to say pain will no longer occur, but that with moderation we can better control the balance between activity and pain so that our chronic pain is more tolerable and what we enjoy becomes our focus rather than our level of pain. 

Relaxation training becomes more integral for quality of life with the deeper understanding of how emotions and pain affect out nervous system and therefore our stress responses. As mentioned previously, stress responses can increase pain. If we reduce our stress responses, we can reduce our pain as well. Enter relaxation training. There are a multitude of relaxation practices that one may implement in addition to breathing exercises and meditations. Relaxation exercises are not cookie cutter as some are more enjoyable or more effective depending on individual preference. Therefore, it's helpful to experiment with different techniques to discover what is best suited for a person.

The next integral part for increasing quality of life, is engaging in enjoyable activities of interest. I discovered how integral this is to experiencing joy that allowed me to start living my best life. It's the things of interest that really give us quality of life and the ability to engage those things, even when it's in a modified way, we can still extract joy from the experience.

It would not be uncommon along the way of these sessions to encounter cognitive resistance. As discussed earlier, throughout life and in reaction to everyday life experiences, we train our brains to think in certain ways. Unfortunately, we don't always train our thoughts to be the most helpful. Learning and identifying the distorted thoughts we use to view the world with allows for starting to change those negative thought patterns. There are 13 common distortion patterns that we are all guilty of using at some point or another. These include:

• filtering out the positives so that we aren't even aware of them
• discounting positives so they don't even matter
• polarizing thoughts to it's all or nothing, black or white, there is nothing in between
• overgeneralizing one thing and applying it to everything in a never-ending situation
• jumping to conclusions or mind-reading without actually knowing the real situation
• catastrophizing every situation to the worst possible situation, regardless of likelihood
• personalizing things that have transpired as having occurred solely because of ourselves
• fallacies that you have all the control or none of the control in a situation, measuring behavior or situation based off how fair they feel to us and believing that others should change to suit what we want
• blaming others for our feelings
• shoulding ourselves or others to what we expect without allowing for exceptions
• emotionally reasoning that because we feel a certain way about something, that must be a fact
• labeling or mislabeling ourselves or others with judgement and without considering context
• believing we're always right despite evidence and the feelings of others

As we become more familiar with when we're engaging in cognitive distortions, the more we will become aware of them and be able to catch them so that we can change them. My favorite way to change thought patterns is using cognitive reframing or restructuring to challenge the thought and replacement with a slightly updated new thought. 

Cognitive reframing isn't changing a thought completely, it's simply tweaking it. When we whole-heartedly believe a thought to be fact, we're going to have resistance to the idea and attempt to completely change that thought to the opposite. Instead, if we complete a simple, small tweak, we will be more successful and over time, with repeated use, that thought pattern will change.

Let's use the thought that "I can't do any activity without having a pain flare!". Breaking that thought down and earnestly looking for what activities do I do that haven't caused a pain flare, no matter how small of an activity it is. It doesn't have to be activities we enjoy even. Simply tweaking the thought from an all or nothing thought to allow for the positive - "I still have pain flares, but I have been able to do X without a flare". 

Challenging questions for that thought could include what small things am I able to do without a pain flare? (Sitting up, drinking water, however small it needs to be). When something is painful to do, how long does the pain last? Does it last the same amount for every single activity I do? Are some things less painful to do or require less recovery time? 

As we challenge thoughts and find exceptions to the thoughts, the more we give back to ourselves, the more grace we allow, and the better we become at seeing the exceptions. In turn, our behaviors change and in turn, our mood. When we feel less hopeless, defeated, even angry about something the more motivated we become and likely to do things and focus on things in life that add to our quality of life. 

Not only does changing negative thought patterns improve mental health and reduce painful emotions that trigger our sympathetic nervous system, but it also increases our coping ability with pain. 

The last piece in CBT-CP is to look at the pain and sleep interaction. Sleep is necessary for body recovery physically and emotionally. Poor sleep can increase our sensitivity to pain. Therefore, practicing good sleep hygiene and even participating in CBT for insomnia can affect pain levels.

Good sleep hygiene includes:

• only going to bed when sleep, not just tired or fatigued
• using one's bed only for sleep and sex
• if unable to sleep after 20 minutes, get out of bed and only return to bed when sleepy
• awakening at the same time every day and going to bed at the same time each night
• avoiding naps during the day
• keeping the bedroom dark, quiet, and comfortable for sleeping
• limiting caffeine intake after 2 pm
• limiting food intake for 3 hours prior to going to bed

Learning how to implement each of these parts in my life has significantly increased my quality of life and how I manage my chronic pain. It took me about a year to find and maintain an effective self-care practice of exercise, pacing, and activity for what works for me. There are times I slip back into old habits, and I have to catch myself so that I can correct. I hope that with time and practice, you'll start seeing changes soon as well.
