Course: Class #: Acupuncture Treatment of Disease 3 1 - Low back pain, glomerulonephritis Date: April 13, 2009 Syllabus review Class attendance: 3 tardies (15 min late or 15 min early departure) = 1 absence. Low Back Pain Low back or lumbar pain (also called lumbago in some publications) affects something like 6 million cases in the US per year. As such, it is widely seen in student clinics and in professional clinics. There are a wide range of etiologies, types and differentiations for low back pain. What follows is a discussion of lumbar pain in some it’s wide variety of flavors. Low back pain can be classified as acute, subacute, and chronic in nature. ☯ Acute: Acute or short term low back pain lasts from a few days to a few weeks. Most causes are mechanical in nature, resulting from trauma such as a sudden jolt (like a car accident or a fall) which stresses the bones and soft tissues (intervertebral discs, muscles, ligaments and tendons). Patients can often pinpoint the painful parts in these injuries. Very serious accidents or osteoporosis can result in breaks to the bone, either lumbar or tailbone, as well as damage to the SI (sacroiliac) joint. Symptoms can range from muscle aches to shooting/stabbing pain, limited range of motion or an inability to stand up straight without pain. While most acute back pain will resolve within a couple of months, some acute injuries may become chronic if not treated. Rest generally results in an improvement in the pain. ☯ Sub-acute: Well, honestly, we didn’t discuss this in class so much and neither does any other source I found, including the Dr. Luo handout. One to 3 months perhaps? ☯ Chronic: Any low back pain persisting for more than 3 months = chronic pain. This suggests deficiency, no? Physically this may be due to osteoarthritis, rheumatoid arthritis, spinal disc herniation, and osteoporosis. Rarer causes include tumors and infections. Sidebar: Pain in the upper back is less likely to be trauma induced, though it can certainly happen. More likely causes are wind-cold invasion affecting the upper back and stress. Bear in mind, however, that aortic disorders such as aneurysms, chest tumors and inflammation of the spine can also result in upper back pain. Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 1 of 13 Interviewing Your Lumbar Pain Patient When you interview a patient with a complaint of low back pain it is important to gather some basic information about their condition. Find out: ☯ Duration How long has it been painful? Helps you determine excess or deficiency, chronic and acute. ☯ Character How do they characterize the pain? ☯ Radiation Does the pain radiate to any area? If so, where and when? ☯ What makes it better or worse ☯ Associated symptoms What other symptoms came along with this pain? Fever, pain on the anterior of the body, etc. ☯ Neurologic symptoms Numbness, tingling and weakness for instance. ☯ Trauma Was there an injury that caused the pain? Find out how the injury occurred – this can help you determine what is injured. Often low back pain will start in one place and refer to another or will start in a localized area and spread to surrounding areas as the muscles “guard” the injury. ☯ Previous treatment What has the patient tried already and what kind of success did they have? Differential Diagnoses for Low Back Pain Aka, conditions associated with low back pain…and there’s a bunch of ‘em! Sciatica OK, this is really a lecture unto itself even though it only got an honorable mention in class. Sciatica isn’t really a diagnosis unto itself so much as it is a collection of symptoms associated with inflammation or impingement of the sciatic nerve. The sciatic nerve is a large nerve exiting the spine in the lumbar and sacrum (L2 to S4), traveling down the leg and branching to supply enervation to the lower limbs. The yellow and green bundle in the pic to the right represent the sciatic nerve. It’s big – about as big around as your index finger. This bundle passes behind the hip joint and goes down the buttock to the back of the leg and foot. Compression of the sciatic nerve in the spine is the most likely suspect for sciatica pain. This happens most often as a result of disorders of the vertebral column, usually the rupture of an intervertebral or lumbar disc. Less likely is primary sciatica which is a disorder of the sciatic nerve itself. (Diabetics sometimes suffer from this. The pain in this case is felt bilaterally. Pain from disc compression on the other hand is unilateral.) Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 2 of 13 Symptoms of sciatica due to compression include shock-like or burning low back pain combined with pain in the buttocks and pain down one leg. Pain is most often felt to about the knee, either on the posterior or lateral aspect of the leg. Pain can go down below the knee, however, sometimes even wrapping to the anterior or medial aspect of the leg and/or foot. You can do some quick clinical tests to determine sciatic pain. The simplest one to do is the straight leg test which stretches the sciatic nerve and spinal nerve roots. Have the patient lay flat on their back and then you lift their affected leg to the 30 degree mark. Pain felt between 30 and 90 degrees is a fairly good indicator of sciatica. You may need to dorsiflex the foot in order to get the stretch you need. This can also indicate piriformis syndrome (in which the piriformis muscle is pinching the sciatic nerve rather than the bone or disc) or sacroiliac joint involvement. Some practitioners suggest that pain felt between 35 and 70 degrees indicates possible disc pathology while pain felt between 70 and 90 degrees is a good indicator of lumbar joint involvement. Though it’s not covered in class and not on the test, Maciocia and several others recommend Jiaji points in the lumbar, UB 54, GB 30, Huan Zhong extra point, GB 34, and UB 40 to treat sciatica. Herniated nucleus pulposus (with/without nerve impingement) This is also called a protruding, bulging and sometimes a ruptured disc. The intervertebral discs, under constant pressure, can be partially pushed into another space, often space containing the spinal cord or nerve root causing pain. Most herniated discs occur in the lumbar portion of the spine, as this is where most of the weight of the body is carried. Spondylosis (with or without spondylolysthesis) This is a degenerative process of the spine causing narrowing of the spinal canal due to bony overgrowths which results in compression of the spinal cord and nerve roots as well as the intervertebral discs and vertebral facet joints. This can be caused by wear and tear on the discs. Patients with spondylosis may experience stiffness in the mornings after waking from a nights’ sleep and/or may feel pain after walking or standing for a long time. Anther term for this is spinal stenosis which also refers to bony overgrowth. Spinal stenosis is most often used to refer to bony overgrowth which results in stiffening of the spine. When X-rayed the spine looks like bamboo. This is often caused by an autoimmune disorder. A blood test for B-27 can show a propensity for this type of spinal anomaly. Spinal (and cervical) stenosis can also narrow the spinal canal leading to impingement of the nerves and discs. Spondylolisthesis refers to the anterior dislocation of one vertebra over another producing pressure on the spinal nerves. Scoliosis and Other Skeletal Irregularities Skeletal irregularities produce strain on the vertebrae and supporting muscles, tendons, ligaments, and tissues supported by spinal column. These irregularities include: Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 3 of 13 ☯ ☯ ☯ ☯ ☯ Scoliosis, a curving of the spine to the side Kyphosis, in which the normal curve of the upper back is severely rounded Lordosis, an abnormally accentuated arch in the lower back Back extension, a bending backward of the spine Back flexion, in which the spine bends forward. Sacroiliac Joint Dysfunction The sacroiliac joint is fairly fixed large joint in the body. It is held together by some very large ligaments. The SI joint forms part of the ring that is the pelvis and these ligaments hold the whole thing together rather like a hoop of metal around a barrel. If the ligaments are torn or stretched…like in pregnancy (which causes the release of hormones to relax these ligaments) the joint gets more flexible. The more pregnancies, the more flexible it is. Later in life it tends to ankylose…grow together. This takes away the shock absorbing capabilities of the joint. Also, with multiple pregnancies, the incidence of arthritis in the SI joint increases. Lumbar Transverse Process Syndrome L3-L4 especially L3 transverse process hurts to palpate. Muscle on the affected side will feel stiff. Rare Causes… ☯ Infection (such as kidney infection, shingles, tuberculosis) ☯ Connective tissue disease (such as ankylosing spondylosis) ☯ Tumor ☯ Referred pain (from a kidney stone, abdominal aortic aneurysm, etc.) ☯ Spinal stenosis A physical exam to check for causes of lower back pain would include ☯ Range of motion tests such as flexion, extension, and rotation to the left and right. ☯ Inspection for obvious signs of deformity While forward flexing, look for one shoulder higher than the other, suggesting scoliosis ☯ Palpate the spinous process and surrounding tissues for tenderness ☯ Note any paraspinal muscle spasms ☯ Neurological exams Should you be interested, check out the Physical Assessment 2, specifically class 5. That was all about spinal evaluation. Class 4 was about neurological testing. Biomedical treatments for low back pain are largely dependent upon the cause. If there are no symptoms that might cause long term problems, pain is usually managed conservatively since 80-90% of low back pain resolves without further problems in 2-3 months. Further treatment includes: ☯ Reduced activity and rest ☯ Pain management with NSAIDS and Tylenol Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 4 of 13 ☯ Modalities such as ultrasound, ice, and heat ☯ Gentle flexibility exercises for the back and hamstrings ☯ Strengthening of the support muscles of the abdomen and trunk If symptoms don’t improve over the course of 4 weeks most practitioners will then consider radiographic studies. TCM Mechanism The low back is the “Residence of the Kidneys,” as this area of the body is the most closely related to the Kidney system. The health of the Kidneys is often reflected in the status of the lower back. Kidney deficiency or blockage in the lumbar channel(s) TCM Etiology 1. Invasion and retention of pathogenic cold, wind and damp. Retention of cold, wind and damp in the channels and collaterals that flow through the lower back causes constriction and obstruction of the Qi in the meridians and collaterals (often this is cold attacking the Yang meridians, especially the BL, GB, Du vessels) which causes pain. The Neijing says, “ If there is free flow there is no pain; if there is no free flow, there is pain.” Precipitating factors causing this retention are likely to be living in cold damp places, exposure to rain, wading in water, being drenched in sweat. 2. Damp heat retention in the lower jiao This is more often damp heat attacking the Liver, Spleen, and Kidney channels – Yin channels. Patients may have a short or long history of low back pain. Damp heat can come from chronic damp retention, acute damp and heat retention. 3. Blood stasis obstructing channels and collaterals Often due to traumatic accident causing acute lumbar muscle sprain which is then not treated correctly, lingers a long time and becomes a chronic condition. This also happens to patients whose jobs or lifestyles involves repeat strain to the lower back (i.e., due to carrying heavy loads frequently). 4. Kidney deficiencies This is most frequently a result of aging. Kidney deficiency of Yin, Yang, or Qi leads to low back pain due to pinching and compression of the nerve. Kidney Essence xu, however results in congenital kidney deficiency such as Adult Polycystic Kidney Disease (APKD) for instance or Infantile Polycystic Kidney Disease (IPKD). Both result in cysts of fluid in the Kidney expressed at different ages. Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 5 of 13 Kidney xu can involve both the Kidney organ and associated channels, Kidney, Bladder, Du, and Dai channels. Dai crosses the regular channels of the Stomach, Bladder, and Gallbladder channels; Liver, Spleen, and Kidney. All channels are bound by the Dai channel. The lumbar area holds most of the weight of the body – as such part of the Dai channel’s job is to support the lumbar area. Weakness of Kidneys can also be to overwork or excessive sexual activity which results in poor nourishment of the meridians of the lumbar region. Differention and Treatment Treatment involves dredging the meridian passages in the case of excesses and tonifying Kidney Qi in the case of Kidney deficiencies of any kind. Points are mainly selected from the Du and Foot Taiyang (BL) channels in treating lower back pain. Basic points: ☯ KI 3 Treats any kidney deficiency (qi, yin, yang, essence). This is the “Tai xi” or Great River, the Shu Stream point for the Kidney. ☯ UB 40 Use bleeding, cupping, needling. This is one of the 4 key points. ☯ GB 34 Influential point of the tendons - relaxes ligaments and tendons, and is especially good for sprains ☯ Ashi points of the lumbar region Differentiations See http://www.yinyanghouse.com/treatments/acupuncture_for_low_back_pain if you want a more thorough discussion of the differentiations and treatment plans than we got in class.

Look for congenital problems. Dr. Luo didn’t talk about it much, but the only way to build essence according to Will Morris is to do Qigong. Other Treatments: ☯ LI 10 – for acute injury. Insert needle, get strong stimulation, have the patient do gentle movement with the back. But keep the arm still! ☯ Yao Tong – 2 points on the dorsal aspect of the hand, just distal to the junction where the 1) 2nd and 3rd and 2) 4th and 5th bones meet. This too is a movement treatment for lumbar pain due to sprain, etc. ☯ Bleeding/cupping Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 8 of 13 ☯ UB 40 ☯ Local points – treat the tender point specifically. ☯ ST 38 – for lumbar pain.

Manipulate the needle with the reducing method for 1-2 minutes. If the patient responds well, repeat this process a few times then insert auxillary/local points and retain for 15-20 minutes. Empirical Points: ☯ GV 26 - if pain is only on the midline of the back and patient has flexion/extension difficulty ☯ SI 3 - if pain is on the posterior-midline and also lateral and/or patient has torso rotation difficulty ☯ Yaotongxue - if pain is on either side of the posterior midline, pain above UB 23 ☯ UB 40 - acute back pain on the UB meridian, pain below UB 23 ☯ UB 37 - in lieu of UB 40 if there is pain and tenderness here and no congestion of blood vessels at UB 40 ☯ GV 8 - stiff and/or rigid spine Acupuncture Treatment of Disease 3 – Spring 2009 www.CatsTCMNotes.com Page 9 of 13 Glomerulonephritis Glomerulonephritis (also called glomerular nephritis or GN) is a renal disease characterized by inflammation of the glomeruli of the kidney. For a biomedical review of this functional unit of the kidney, please click here. GN can be of primary cause (causes intrinsic to the kidney) or of a secondary nature (bacterial, viral or parasitic infections, drugs or systemic disorders like SLE or vasculitis). It can present with: ☯ isolated hematuria or proteinuria ☯ as part of a nephrotic or nephritic syndrome in which the kidneys are damaged and thus leaking proteins or blood into the urine ☯ as a component of acute renal failure ☯ as part of a chronic renal failure In many cases the cause is unknown – approximately 25% of patients with chronic GN have no prior history of kidney disease and the disorder first appears as chronic renal failure. Autoimmune disorders have been known to result in GN. The chronic form of glomerulonephritis may develop after an acute phase. Symptoms: ☯ Lumbar pain This is a common first symptom. ☯ Proteinuria Protein in the urine can result in foamy urine. Patient will often get very slender as well since the body is not being nourished. ☯ Hematuria ☯ Edema ☯ Hypertension ☯ Abnormal BUN and Cr results – higher than normal Chronic renal failure patients may eventually manifest with the following symptoms: ☯ Unintentional weight loss ☯ Nausea/vomiting ☯ Fatigue ☯ Decreased urinary output ☯ Need to urinate at night ☯ Easy bruising ☯ Decreased levels of alertness (i.e., drowsiness, delirium, coma) ☯ Muscle twitching and cramping ☯ Seizures ☯ Generalized itching Treatment depends upon the cause. Common treatments include blood pressure medications to relieve hydraulic pressure in the kidneys, corticosteroids, immunosuppressants, and dietary restrictions on fats, proteins, fluids, and salts.
