“Fear of movement, pain catastrophizing, anxiety and nervous system sensitization appear to be the main contributors to pain and disability.” – Lorimer Moseley
Based on previous experiences with pain, their nervous system has decided that protection against movement is necessary to prevent pain and injury. At that point, the therapist’s goal becomes gaining the trust of the client’s nervous system so joints can be moved passively. Without that trust, you cannot move them. If you cannot move them, you cannot retrain movement and get them out of pain.
I had a new client recently with chronic bilateral low back/sacral pain. She had her left hip replaced 7 years ago and her right hip replaced 2 years ago. She described her right hip replacement as “bad” and that the neck of the femur was too long and femur head was too big. The surgeon thought revision surgery might be necessary. She had many pain issues, but the low back pain was the most prominent so we decided to focus on that.
It is important in cases like this to let the client know, repeatedly, that they are in charge and you are not going to do anything that causes pain. Some discomfort, perhaps, but nothing that exceeds their basic pain tolerance and nothing sudden. That would be counter-productive. With CTB, we are working to down- regulate a pain sufferer’s nervous system by giving them experiences of pain-free movement and gently increasing the pain-free range of motion. That’s why we use a number scale, one through ten, to keep all movements and palpation below the perceived pain threshold of the client. The client tells us what they are experiencing and where so we can keep everything below threshold. This feedback system works very well and most of the time the client’s sensitization will start dropping immediately. However, how you talk to the client is one thing, how you move them is another.
Talk is cheap. Action speaks louder than words.
Talk is cheap and very much at the surface layer of your relationship with the client. Meanwhile, beneath the verbal dialogue, the client’s nervous system is carefully sizing you up to determine if you are a threat. Your nervous system has to prove to their hypervigilant nervous system that you are a friendly, helpful entity that is not going to hurt them. You accomplish this through your own relaxed, confident and controlled movement.
Be patient, start small and slowly build on the successes. Every experience of pain-free movement adds to the evidence that it is possible and down regulates the client’s nervous system. This seems to happen in an exponential expression. So it is very slow going at first but gets better and better, like a snowball gaining momentum and mass as it rolls downhill.
Use the breath.
Our parasympathetic nervous system facilitates relaxation during exhale. Coach the client to inhale and exhale and time your breath with theirs. On the exhale, you both will relax more.
Contract/Relax with breath.
Combining contract/relax movement with breath is a key part of the CTB treatment cycle and greatly facilitates trigger point release and pain desensitization. Instruct the client to gently contract the agonist muscle, have them take an inhale and hold their breath for at least 5 seconds, then have them exhale and relax everything. When you feel them relax fully, take the agonist muscle into passive length. If the client is very guarded and pain sensitized, do this early and often.
Another key principle in CTB is feedback compression on agonist muscles, antagonists and sometimes as many muscles in a functional group that you can touch at once. Our preferred CTB treatment positions are ones in which this is possible. Often I have a client limb totally wrapped up with my body. It not only makes the limb feel totally secure so the client can relax the muscles, the contact gives the client’s nervous system additional inputs to calculate and facilitates a change in pain perception.
Years of constant low back pain, gone in one 90 minute session
In the treatment of this hip replacement client with low back pain, I employed all these techniques and strategies. She got up from the mat, with no back pain for the first time in years and easier movement in her hips. After 2 weeks, no return of the pain. I really only spent 10 minutes on each hip in the optimal treatment position at the end of the session, but it took me 70 minutes of patience and baby steps to get there!
Most sciatic pain is caused by trigger points in muscles.
Sciatica is the most common lower body pain complaint that we see in our clinic. It is a description of radiating leg pain, not a diagnosis. Although most physicians and physical therapists will assume that it is caused by nerve entrapment in the lumbar spine (radiculopathy) or nerve entrapment by the piriformis muscle, we have found that most sciatic pain is caused purely by trigger points (taut muscle fibers) in the gluteal and quadratus lumborum muscles. Knee pain and ankle pain is also often due to trigger points in these hip and low back muscles. Sometimes the client feels the pain down the entire lateral or posterior leg. But sometimes only a portion of the sciatic pain distribution pattern is felt, in the knee or in the ankle. The following case study illustrates this.
Lateral Sciatica Case Study – August 2016
During the interview she reported intermittent right lateral thigh pain, and right lateral knee and ankle pain. Movement seemed to help, but if she walked a lot she would feel lateral thigh pain, knee and ankle pain.
From the initial assessments I postulated that her knee and ankle pain would have strong contribution from her glutes and QL. Her pain is on her right side, same side as her high illiac crest and strong foot hyperpronation. So her QL would habitually be short on the right side and her abducting gluteus minimus and medius fibers would have to work extra hard to stabilize her gait, leading to trigger points.
We started in supine position. I checked the metatarsal-phalangeal joints of her foot and the second toe MTP joint was more distal than the big toe MTP joint, an unstable foot structure (Morton’s foot). I rotated her right ankle and movement was limited in all directions, her lower leg muscles were very dense, probably from having to provide extra stabilization. The vastus lateralis was tender in the mid belly region and also in the more distal oblique fibers that commonly cause lateral knee pain. I could have worked a lot on the quad muscles to treat the knee pain, and on the lower leg muscles including the peroneals to address the lateral ankle pain, but that would not bring lasting relief. The pain source was further upstream.
Leg adduction stretch often reveals myogenic sciatica referral.
Moving up to the hip, there were taut fibers in the TFL and anterior glute minimus but no referral pain on palpation. I had her abduct her leg, contracting the abducting glute fibers, then brought the leg into adduction to stretch those fibers. She reported a “stretch” in her VL. Her knee was straight and the VL was lax, so there was no stretch happening there. This happens a lot. The client reports a “stretch” along the lateral or posterior leg when the only fibers stretching are the glute minimus and medius muscles in the hip. This is sciatic pain referral from the glute minimus muscle. The client has sensation down the leg, and knows the leg is being moved, so perceives the sensation as a stretch.
Satellite pain referral from gluteus maximus.
I had her sit up and round forward so I could look at her spine. As soon as she rounded forward, flexing her spine, she felt pain in her right glute medius area and radiating down her lateral leg. It was possible there was radiculopathy at her lumbar spine when she flexed. As a test, I put her into supine position and lifted her legs, flexing her lumbar spine in the same manner. This time, no report of pain…What was the difference? There was no compression on her gluteus maximus in this supine position. I postulated that when she rounded forward when sitting, the belly of the glute max slipped under the sit bone and the taut fibers there were irritated by the compression. The glute max can refer pain into the glute minimus which then produces the sciatic leg pain. This is known as satellite referral. I put her into side position, palpated the glute max fibers that would slip under the sit bone when she was seated. When compressed, she reported her familiar lateral leg pain. Not radiculopathy – glute satellite referral!
Specific taut fibers can generate specific distal pain.
I proceeded to hunt down taut fibers in her right glute minimus, medius, max and QL. When compressed, all could generate the lateral sciatic leg pain. In her lateral superficial QL I found a particular fiber that would specifically generate only the lateral knee and ankle pain. I also found a specific glute medius fiber that would generate the same specific knee and ankle pain. This is a perfect example of satellite trigger point referral and the “cross referral” that happens between the QL and the glutes. It is also a good example of how a specific taut fiber can refer a distinct distal pain, not the whole sciatic pattern. After releasing the taut fibers with compression during passive movement and contract/relax stretching, the client had no active pain.
I armed her with a lacrosse ball and taught her how to compress her glutes with it, and to get compression on her QL. I also taught her contract/relax stretching for QL and glutes. She has a desk job and is sitting a lot during the day, so I encouraged her to evaluate her posture, to sit upright so her sit bones are directly on the chair without compressing her glute max. And also to get up frequently and move. I saw her twice after the initial treatment. Each time she came to the studio with less initial pain and we got it to zero by the end of the session. Her husband came to the third session and I coached him in compression techniques so he could assist in his wife’s home treatment. By the end of the session they were confident they could eliminate the sciatica with what they had learned.
