Would you or your practice have better piece of mind if one of the computers in your office had a summary of every original chiropractic research article conducted since the beginning of time? Mine does. Of course this would not be so worth while if the data-bank was not easily searchable by technique, health condition, and more. The fact that I can print a bibliography on any searches I do and can choose whether to include a summary of each individual research paper found in my search helps as well. A nice fringe benefit of being involved with the ICA’s Best Practices and Practice Guidelines (BPPG) project (www.IcaBestPractices.org) is the fact that the database our group compiled sits on a computer in my office for quick reference anytime.
One day, this database should be available online where it can be used by any ICA member the same way I can use it right now in my own office. Just for fun, I would like to overview selections from Chapter’s 10 and 11 of the ICA BPPG document here to elaborate some of the 339 or so named health conditions published chiropractic research has shown chiropractic has been helpful for. For those of you wondering how much of this information is based on symptom outcomes and how much is based on subluxation correction, I would ask the individual authors of the individual research studies their intent. From reading through, most research has been conducted with the focus and intent of correcting subluxation. Because of the chasm in our profession between those who embrace the correction of subluxation and those who refute it as clinically trivial, I would emphasize the information here is based on outcomes from the chiropractic procedures used regardless of the chiropractic clinicians intent. In other words, the research shows chiropractic works.
Curious for Some Search Results…
Search 1: Searching on, “Gonstead,” which I believe is the second most utilized chiropractic technique (diversified is the first), I found the average number of treatment visits was 29 over 20 weeks of care. Conditions in these papers shown to improve are as follows: Bell's Palsy, TMJ, Low Back Pain, Myasthenia Gravis, Bone Fracture, Headache - Migraine, Enuresis - Nocturnal, Occulomotor Palsy, Colitis, Vertigo, Otitis Media, Attention Deficit Hyperactivity Disorder, Dejerine-Sottas Disease, Asthma, Erb's Palsy, Scoliosis, General Chronic Degenerative Diseases, Infertility, Hot Flashes, Headache - Tension , Encopresis, Hypertension, Colic, Occupational Stress Syndrome, Whiplash, Anxiety, Nursing - Trouble Breast Feeding, And High Blood Pressure. One scoliosis paper did not show improvement, but others did. All other listed conditions showed improvement.
Search 2: Since I mentioned it I then searched on, “Diversified,” and found the average number of treatment visits shown was 20 over 18 weeks. Is 20 visits a magic number? Remember, this is research and many studies only treated once before re-evaluating so these studies skew the number of visits to the low end. 15% of the papers looked at only showed one or two treatments for the sake of maintaining research controls. 30% of these papers showed treatment visits between a low of 40 and a high of 250 to achieve their clinical results. One percent of studies did not show positive outcomes (this means 99% showed positive outcomes at low consumer cost) and 24% of these studies never mentioned how many visits were seen at all. The average number of weeks treated here was 18 but when excluding studies where only one or two or three treatments were applied, the average changes quickly to 26 weeks of treatment. Remember, the visit numbers commonly are for research to show measurable improvement and not resolution of the problem.
Conditions shown in this search to improve are as follows: ADHD, Allergies - Hay Fever, Angina Pectoris, Ankle Inversion Sprain, Ankle Pain, Ankle Sprain, Ankylosing Spondylitis, Anxiety, Aphasia - Acquired Verbal, Arnold-Chiari Malformation, Asthma, Auditory Neuropathy, Developmental Delay, Autism, Back Pain, Bladder Infection, Breathing - Difficulty, Capsular Fibrosis, Cardiac Arrhythmia, Carpal Tunnel Syndrome, Chest Pain, Child-Bed Fever, Colic, Constipation, COPD, Cough, Cranial Plagiocephaly, Deafness, Diffuse Idiopathic Skeletal Hyperostosis (DISH), Disc Degeneration, Disc Disease, Disc Herniation, Doule Crush Syndrome, Dysarthria - Cervical, Dysmenorrhea, Eczema - Acute Ectopic, Elbow Pain, Encopresis, Enuresis, Eustachian Tube Blockage, Eye Pain, Failed Back Surgery, Femoral Nerve Entrapment, Foot Pain, Gastroesophegeal Reflux Disease, Hallux Rigidus, Hamstring Strain, Headache, Headache - Cervicogenic And Vertigo, Headache - Migraine, Headaches - Cluster, Hearing Loss, Hiccups, Hip Pain, Hot Flashes, Hypertinsion, Hypertonia & Hyperreflexia, Immune Status, Infertility, Insomnia, Intercostal Neuralgia, Irritable Bowel Syndrome, Klippel Feil Syndrome, Knee Pain, Lateral Epicondylitis, Lateral-Flexion Asymmetry, Low Back Pain, Menopause Symptoms, Menstrual, Meralgia Paresthetica, Metabolic Disorders, Metatarsalgia - Primary, Motion Asymmetry - Cervical, Musculoskeletal Pain, Myasthenia Gravis, Myofascial Pain Syndrome, Neck Pain, Nursing - Difficulty, Nursing - Dysfunctional, Nursing - Hypolactation, Ochronotic Arthropathy, Otitis Media, Pain, Paralysis, Paralysis - Infantile, Paralysis - Left Arm, Patellofemoral Pain Syndrome, Pelvic Pain, Plagiocephaly - Non-Stenotic Deformational, Plantar Fasciitis, PMS, Pneumonia, Pregnancy, Pregnancy - Low Back Pain, Premature Ventricular Contractions, Radiculopathy - Cervical, Reiter's Syndrome, Rett Syndrome, Rotator Cuff Tear, Sacroiliac Syndrome, Sciatica, Scoliosis, Scoliosis - Mechanical, Shoulder Injury, Shoulder Pain, Shoulder Pain - Chronic, Shoulder-Hand-Syndrome, Sinusitis, Spasmodic Dysphonia, Spinal Cord Encroachment, Swimmer's Shoulder, Thoracic Disc Herniation, Thoracic Nerve Root Injury, Tight Muscle, TMJ, TMJ Pain, Torticollis - Congenital, Torticollis - Congenital Muscular, Transient Syncope, Tremour - Intention, Ulnar Neuropraxia, Urinary Incontinence, Uveitis, Vertigo.
Incidentally, a whopping 1.6% of diversified research studies failed to show improvement in the things being measured.
Search 3: How about, “Headaches?” I show approximately 138 research studies where headaches were looked at and 3 (2%) showed no significant improvement. Of these three studies not showing improvement, one showed an exacerbation of symptoms after the first adjustment, the second discovered the patient had renal cell carcinoma and the third showed headache as related to sleep apnea and did not report on whether the headache changed during treatment. Subjects of these studies were seen an average of 39 visits in 22 weeks.
Headache related conditions in these papers shown to improve are as follows: Asthma, Colitis, Constipation, Difficulty Walking, Disc Rupture, Dysmenorrhea - Primary , Eye Pain, Fracture - Lamina, Fracture - Pelvic, Gangrene, Headache, Headache - Cervicogenic, Headache - Cervicogenic And Vertigo, Headache - Migraine, Headache - Occipital, Headache - Tension, Headaches - Cluster, Headaches - Suboccipital, Hemiparesis, Hyperflexion-Hyperextension Syndromes, Hypertension, Indigestion, Infection - Acute, Infertility, Klippel Feil Syndrome, Leg Pain, Mid Back Pain, Neck Pain, Nervous Breakdown, Numbness In The Upper Extremities, Pinched Nerve, PMS, Polyuria, Purulent Discharge, Radicular - Arm, Sinusitis, Sprained Shoulder, T4 Syndrome, Tic Doloreux, Tinnitus, TMJ, Unexpected Weight Loss, Uterine Cramps, Vertigo, Visual Defect - Monocular, Visual Field - Narrowed, Visual Perception Deficit, Whiplash, Wrist Pain.
Incidentally, 15 of these studies were randomized clinical control trials (Level I Evidence) which are considered to be the gold standard of clinical research.
Chapter 11 of the BPPG document on treatment frequency and duration states, “It has been estimated that, among studies providing a break down on direct costs, the largest proportion of direct medical costs for LBP was spent on physical therapy (17%) and inpatient services (17%), followed by pharmacy (13%) and primary care (13%).”1 While only 3% was reported for Chiropractic Workers Compensation costs in the USA,1 Dagenais et al2 reported an average of 5% from studies in Australia, Sweden, United Kingdom, USA, and Korea. This data is very misleading because these authors stated… that, “Chiropractic,” included Osteopathy costs. Since Osteopathy has a bigger percentage of the health care pie world-wide than does Chiropractic, it is likely, based on this data, Chiropractic represents less than 2% in industrial nations.… “It is a known fact that costs of CAM (Complimentary and Alternative Medicine - Chiropractic) utilization are less than that for standard medical care.3 Thus, to reduce Workers Compensation budgets, it becomes apparent that standard Medical Care and Physical Therapy also need to be audited and guidelines developed to reduce costs within these two areas, not merely in Chiropractic.”
What might lawmakers and insurance companies or even your patients do if some of this information were to become more readily available? All indicators point to chiropractic as a safer, more natural and less costly way to help people. In this environment of evidence based practice, one major problem is only few know what the evidence actually shows. Even still, few understand how to accurately represent the evidence.
This ICA Best Practices and Practice Guidelines is not so much an ICA document as it is a chiropractic document. There is no spin on what research exists as the document shows simply the original clinical chiropractic research that does exist without filter or bias. At that point, the data starts speaking for itself. As a closing note, I want you to know the document is easy to read and not too long (there are many pages of references). It is available for professional review and reference in its draft form at www.IcaBestPractices.org. Please give it a look and then fill out our online survey for practicing chiropractors.
