Dr. Thomas Cotter, DC, DACRB: Growing up a very active kid in Goodland, KS, I played every sport I could. After high school, I went to Kansas State University for engineering but quickly realized that wasn’t the career for me. I spent half a semester wondering what I was going to do. Eventually, I thought about my chiropractor back home. He helped people, he seemed to enjoy his job, he worked with athletes, etc. This thought excited me enough that I changed my major to kinesiology and started down the chiropractic path. The next semester I immediately fell in love with my classes, all the questions I ever wondered about the body were being answered. I then started getting into endurance activities. I was biking and running 15-20 miles per week. As a result, I started experiencing subtle leg pain. I thought no problem, I'll go to my local chiropractor. His response to my complaint was to tell me I needed to stop exercising so much and that he didn't really work on legs and arms. I was blown away. Why was someone in the health field telling me not to be as physically active? And why would he only work on my back? At that moment, I told myself I was never going to tell someone they couldn't do something they loved (unless there was imminent danger of severe injury). After that, I attended Palmer College of Chiropractic. I sought to find the best way to treat people without limiting their loved activities or only treating their spine. I became the president of the Motion Palpation Club, was hired as an intern in the much sought-after rehab department, and attended seminars on the weekends. After I graduated I moved back to Kansas City to set up Active Health KC in Prairie Village.

In regards to chiropractic care, my methods of practice include:

I am certified in Dry Needling I and II as well as Webster technique (a technique for prenatal and postpartum individuals). I look forward to meeting and working with all of you!

How are you different from most chiropractors?

All chiropractors are not the same. Most chiropractors only adjust, which limits what they can effectively treat as well as their results. Dr. Cotter has extensive post graduate training which allows him to treat almost all neuromuscular conditions and obtain results faster.

Why should I go to you instead of my medical doctor for my joint or muscle pain?

While medical doctors help with many problems/diagnoses, most do not have much training in the conservative treatment of joint or muscle pain. If the doctor at Active Health KC thinks you can be more effectively treated by a medical doctor, he will refer you to the appropriate one.

What if I don't want to be adjusted?

Adjusting is not essential for every patient. In fact, several of our patients are never adjusted. If poor joint movement is a contributor to your pain, there are other options besides adjusting, such as gentle mobilizations. Discuss your concerns with the doctor and he will discuss options and come up with a treatment plan that works for you. .

Once you go to a chiropractor, do you have to go all the time or forever?

Not at Active Health KC. Our focus is to empower you, the patient. We want you to be able to understand and be able to self-treat your pain. This minimizes you needing to relying on physician care. While several visits may be needed to correct the underlying problem, our end goal is to work ourselves out of a job,

What can I expect on my first visit?

Your doctor will watch you perform various activities such as walking, stepping off a step, standing on one leg, reaching overhead and other functional movements. You may be asked to perform some simple exercises to see how your body responds. The doctor will also extensively assess the joints and muscles to find which ones may need to be treated. After discussing what was found during the examination, treatment options will be discussed. If we do not think we can help you or that you will benefit from another specialist, we will refer you to the appropriate specialty. Due to the type of activities during the first visit, please bring athletic attire (shorts or sweatpants, t-shirt or tank top).

Are X-rays required?

No, the vast majority of our patients are not x-rayed. We only send patients for imaging (x-ray, MRI, CT) when we suspect a fracture, severe degeneration or possible pathology.

Is it safe for me to get treated if I'm pregnant?

Absolutely. In fact, pregnancy is one of the top predictors of back pain. Historically it has just been accepted as a part of pregnancy, but back pain doesn't have to be. Pregnancy is full of other changes, struggles, and excitement, don't let pain add to that. Have our doctors develop a treatment plan to effectively and safely treat your pain.
