Biomarker for Concussions

I am Jessillyn Howard, one of MOG’s athletic trainers.  Driving down the road one day, I heard two radio hosts discuss a blood test that is able to identify a concussion. “That’s awesome!” I thought, “A test to identify concussion would eliminate any guess work and be proof to athletes, coaches, and parents when return to play is questioned.” My hopes, however, were crushed when I read the article published by NATA named “How to Address the New Blood Biomarker Test.”

In this article, the author disproves these claims made about this test. This biomarker can be used to detect intracranial hemorrhage, or bleeding between the brain and the skull, without use of a CT scan. This is helpful in limiting x-ray exposure to patients in which intracranial hemorrhage is suspected. This test, along with any other test or imaging, cannot diagnose concussion. The article states, “concussion remains a clinical diagnosis determined by the mechanism of injury, on-field signs and patient-reported symptoms.” This only solidifies the need for athletic trainers not only in schools, but anywhere sports-related concussion may be possible.

Hey Trainer! My neck can do what?!?

My name is Jay Phillips and I am a Certified Athletic Trainer. I want to talk briefly about neck strength and the possible relationship between neck strength and reducing the risk for concussion in high school sports. As spring football and spring sports arrive I am constantly hearing one question over and over again from coaches, players, and parent’s alike, ‘what else can be done to reduce the risk of concussions?’ Well, there has been research that shows for every one-pound increase in neck strength, odds of concussion decreased by 5%. The research also shows that observing an athlete’s neck size might be a useful tool in screening athletes that just might be at a higher risk of concussions and could possibly be included in early prevention programs. So, if you work with your athlete to increase his or her neck strength and neck size, your efforts should result in a decrease risk of concussion.

Glenohumeral “Shoulder” Arthritis

Have you even woken up in the morning with stiffness in one of your joints? Do you find yourself noticing clicking, popping, or grinding when you move your joints? What about swelling especially after using the joint? You may be one of several million people in the United States who is affected by osteoarthritis. Osteoarthritis is a process that may affect any joint in the body including the shoulder. Arthritis is known as general “wear and tear” of the cartilage in the joint and generally affects people older than 50. The purpose of the cartilage is to provide a smooth surface so that the bones move with ease. As this cartilage wears away, the ragged surface of the cartilage and then the surface of each bone begins to rub together causing inflammation to occur which leads to pain. Once the process begins there is no cure, but fortunately there are several treatments to help alleviate the associated symptoms.

Today we’ll discuss arthritis of the shoulder, or glenohumeral joint. As demonstrated in the picture below, the shoulder is made of three bones: the scapula, clavicle and the humerus. Shoulder arthritis occurs in the glenoid of the scapula and the head of the humerus.

Symptoms include pain, a grinding sensation with movement, and stiffness. The severity may range from a mild nuisance to debilitating. When discussing your symptoms with your healthcare provider, they may obtain an x-ray of your shoulder. Some of the findings of an arthritic shoulder are demonstrated in the picture below. The x-ray on the left demonstrates a normal healthy shoulder and the one on the right demonstrates an arthritic shoulder. As we compare the two x-rays, we notice that the arthritic shoulder has a loss of the joint space and bone spurs (aka osteophytes).

It is always important to discuss your symptoms with your healthcare provider before beginning any treatment regime. Nonoperative treatments may include suggestions such as over-the-counter non-steroidal anti-inflammatories (NSAIDs), such as Ibuprofen or Aleve, application of heat or ice, home exercises, and steroid injections. For those with advanced arthritis, your healthcare provider may refer you to an orthopedic surgeon for consideration of a total joint replacement.

In the past few years, we have seen the media bring the subject of concussions into the spotlight. One movie in particular, “Concussion” starring Will Smith highlighted the potential long-term effects of repetitive brain trauma in NFL players. The Center for Disease Control estimates that 1.6 to 3.8 million people in the United States will suffer a sports-related mild traumatic brain injury this year, which we can all agree is a significant number. This raises several questions with athletes, parents, coaches, and athletic trainers. How do we know if an athlete has sustained a concussion? How should they be treated? When can they return to their daily activities, school, and sports? How are they prevented?

Concussions have several different definitions ranging from “complete loss of consciousness” to “getting your bell rung”. In the 2016 Journal of the American Academy of Orthopaedic Surgeons article Concussions in Sports: What Orthopaedic Surgeons Need to Know? it was stated “The Concussion in Sport Group formally defined concussion as a complex pathophysiological process affecting the brain, induced by biomechanical forces.” What does this mean? Essentially, after the brain sustains an injury whether direct or indirect, the chemicals produced in the brain go into overdrive leading to symptoms such as confusion, headaches, irritability, nausea, vomiting, depression, or dizziness. Why don’t we just order a CT or MRI to determine if a concussion is present? A great question! The answer is that these tests are typically normal in a concussed patient and do not help us with diagnosis. This is why it is important for players, parents, coaches, and athletic trainers to know the symptoms. The severity of the symptoms can range from person to person. This in turn can make it difficult to determine if an athlete has sustained a concussion, but once the symptoms are recognized it is essential for them to be removed from the sport until cleared by a medical provider.  Your family physician, a sports medicine physician, or a neurologist are doctors that can treat patients with concussions. If a player returns to sports too soon or before being cleared by a doctor, it may prolong or even worsen their symptoms.

Once we have determined an athlete is concussed, how should they be treated? The answer always incorporates REST in the treatment plan! Both mental and physical rest may be necessary until patients are symptom free. We all know what physical rest is, but what is meant by mental rest? This includes limiting television, video games, and occasionally reading until symptoms resolve. Both players and parents of young athletes must be educated on the importance of being symptom free prior to return to play. While concussions may not be 100% avoidable, prevention is still an important factor. Making sure players have proper equipment and understand safe techniques for their sport can potentially aid in the prevention of concussions.
