Does Chiropractic Work?: Chiropractors

Chiropractic Scientific Evidence:Toronto Downtown Chiropractor

Have you thought about seeing a chiropractor for your pain?


Is there evidence for what chiropractors do?


In this article I give you the plain evidence for what chiropractors treat, proven by research.  I also point out the conditions that aren’t proven.


If you are looking for a chiropractor you should seek out a chiropractor that does treatment that is backed up by evidence. This is an evidence-based chiropractor. For more articles on choosing a chiropractor look here and here,


The Evidence For Chiropractic


Chiropractic spinal manipulation is widely used for the treatment of lower back pain, neck pain, and headaches, whether acute or chronic. It is also frequently used for pain in other areas, such as the shoulders, knees, jaw, ankle and foot.

Numerous studies proves that chiropractic is safe and effective backed up by research. Not all research is created equally though. The best types of research are:


  • Randomized Controlled Trails.
  • Systemic Reviews (A Review of Many Studies).


The evidence I present here are restricted to only these two types of research.

Levels of Evidence: Chiropractors: Does Chiropractic Work:Toronto Downtown Chiropractor



Effectiveness of manual therapies: the UK evidence report


Chiropractic & Osteopathy 2010, 18:3  Systems Review


Chiropractic is effective for:


    1. Acute, Subacute, and Chronic low back pain.
    2. Migraine and cervicogenic (headache that comes from the neck).
    3. Cervicogenic dizziness (Dizziness that comes from the neck).
    4. Acute/subacute neck pain.


Evidence is not conclusive for the following conditions according to the research. My experience has been that chiropractic is highly effective for the conditions listed below (except #7 and #8) especially when combined with rehabilitation, acupuncture, postural exercises,  modalities like laser and ultrasound. For the most part though researchers likes to check only one thing at a time to find out what is working. Thus most research doesn’t test real-life clinical treatments. Why? Most chiropractors do more than just manipulate.

  6. Fibromyalgia
  7. Premenstrual syndrome
  8. Pneumonia in older adults.


Chiropractic has not been proven to help any of the following conditions. If a chiropractor is making these claims the research to date has shown that chiropractic is ineffective at treating these disorders..


If a chiropractor tells you that there is research that backs up these claims, they are unsubstantiated. You should leave the clinic. [7],[8],[9]

  2. Dysmenorrhea (Menstrual Cramps)
  3. Hypertension (High Blood Pressure)

  5. Enuresis (Bed Wetting at night)
  6. Infantile colic
  7. Mental Health Conditions such as depression phobias or anxiety disorders


British Study Comparing Chiropractic and Hospital Treatment [1],[2]


British Medical Journal 1990 & 1995: Randomized Controlled Trail


The Medical Research Council (government funded) in England did a large study of 741 people to compare hospital outpatient treatments to chiropractic clinical treatment.


  • This Randomized Controlled Trail showed that the chiropractic care group had significantly better long term benefits that started soon after treatment started.
  • The greatest benefit was for chronic and severe low back pain patients.
  • A longer term follow-up study showed longer lasting effects for the chiropractic group.
  • Less lost time at work in the chiropractic group.


This means that chiropractic when compared to medical care and physiotherapy resulted in better results in less time, and a longer term benefit. Unlike most trails this was real situation in which chiropractors were able to provide all the treatments chiropractors believe would help their patients like, exercises, posture advice, muscle work like myofascial releases and spinal manipulation.

British Study Comparing Manipulation, Medical Care and Exercises[3]


British Medical Journal 2004: Randomized Controlled Trail


The Medical Research Council in England did a third follow-up study of 1334 people to compare spinal manipulation, exercise classes and general medical care.



  • Spinal Manipulation is cost effective compared to “best care” for lower back pain currently offered.
  • Spinal Manipulation is a significantly better treatment compared to medical care for the full year of the trail.
  • The “right” exercises improve people only up to 3 months.
  • Spinal Manipulation alone and manipulation followed by exercise provide cost-effective additions to care in general practice.


This means that spinal manipulation followed by exercises provide the best care for people.


Chiropractic Hospital Treatment Compared to Medical Managment for Acute Low Back Pain [4]


Spine Journal 2010: Randomized Controlled Trail



  • Chiropractic care was compared to family physician care for acute low back pain.
  • Chiropractic care included reassurance, tylenol, 4 weeks of chiropractic manipulation,  and return to work in 8 weeks.
  • Physician care was usually what was recommended  ie physiotherapy, medication.

Chiropractic care including spinal manipulation significantly improves acute low back pain compared to the usual family physician care. This study was performed by medical doctors and chiropractors.

North American Spine Society Study for Spinal Manipulation for Acute Low Back Pain [5]


Spine Journal  2010: Systems Review



  • This study reviewed 14 randomized controlled trails with spinal manipulation.
  • Results suggest that lower back manipulation (chiropractic adjustments) achieve equivalent or superior improvement in pain and function when compared to other treatments.
  • Other treatments included modalities (machines like laser, ultrasound and shockwave), medications, education and exercise.

    Hi Dr Ken,
    My sister has really terrible TMJ. Any advice for finding a chiro who specializes in treatment (we live in Vancouver BC) Thank you kindly in advance for any suggestions.

      Thanks for your question Jennifer. Use keywords TMJ, TMD, chiropractor, reviews in different combinations with possibly Vancouver.

      Hope that helps your sister’s TMJ.

    Please will you advise if I should follow your guidance of self rectification and scrap any manipulation that my Chiro is insisting I see him once a week for. I have a disk bulge / hernia. Some websites say that Chriopractic methods for this type of issue is ineffective as they refer to it like trying to squeeze toothpaste back into the tube apparently and therefore spinal manipulation is not suggested?

      Thanks for your question Nicola. Chiropractic works well for disc herniation as does mobilization and exercises.

      Why don’t you try these exercises.
      You should do these supervised by your chiropractor. Your chiropractor should have exercises for you. Ask what kind of exercises they are like are they stabilization exercises or exercises designed to help put the disc back into place, along with mobilization and manipulation.

      If the chiropractor can’t do that get yourself a different chiropractor that does rehabilitation. Sounds from first impressions that your chiropractor doesn’t do this but you should look in to it.

      Hope that helps your possible disc bulge or disc herniation.
