Pain Control for Athletes: What Works?

Athletes often fight through their pain to reach their ultimate goals. Specific pain therapies may get them back to performing at their best.

When athletes in pain seek medical help, they tend to have one thing in common. Whether they are professionals or amateurs, they want to get back to their workouts and events as soon as possible. Ankle sprains, shin splints, shoulder injuries, tennis elbow, plantar fasciitis, spine-related pain conditions and ACL tears are just some of the common pain-specific musculoskeletal conditions a practitioner may come across in athlete patients.1

Ongoing research from Canada reveals that pain does not affect the performance of all athletes equally. Some, in fact, perform better when in pain, according to Karen D. Davis, PhD, professor of surgery at the University of Toronto, and head of brain imaging and behavior-systems neuroscience at the Krembil Brain Institute at Toronto Western Hospital. These findings, replicated in her previous studies over the years, has led Dr. Davis to classify athletes in pain as either A-type or P-type. The A-types can focus their attention on making their sports goal: running the race, beating the competition, etc. Their intent is so strong that they do well in their sport despite the pain—and sometimes even perform better than when not in pain. P-types, however, focus intently on the pain and do not usually perform well, as their attention is diverted.

Consider the Type of Athlete Being Treated

In a recent study, Dr. Davis first classified 51 healthy people as either A-types or P-types, based on how they performed a complex mental task when exposed to a painful stimulus, compared to when they were not exposed to it. Next, she administered a functional MRI (fMRI) scan, focusing on neural activity in the executive control (EC) network and the salience network. EC is known to optimize a person's behavior in response to what is occurring in their environment, while the salience network helps to determine which stimuli deserve attention.2

A-types demonstrated more flexibility in both networks, which may explain how they are able to prioritize performance over pain, Dr. Davis explained. “About half the people in our initial sample actually did the task faster and better when we were administering a painful stimuli,” she told Practical Pain Management (PPM). With her research ongoing, Dr. Davis could not conclude if it is possible to change a P-type into an A-type.

As a physician trying to help athletes in pain, simply knowing that pain affects an athlete’s performance differently may guide approaches for pain control. Below are a few tried-and-true therapies that may be used, according to clinicians who work regularly with athletes.

Elevation & Ice—In the Correct Form

Asking a patient to “elevate and ice” is a common first-line technique, but this approach is often not explained correctly or misinterpreted, said Craig Spurdle, MD, an orthopedic surgeon and sports medicine specialist at Nicklaus Children's Hospital in Miami. A physician for the United States Ski Team, Dr. Spurdle works with pediatric and young adult athletes at all levels.

According to Dr. Spurdle, most people think about elevating only the injured area. “Instead, the whole extremity needs to be elevated.” It is also important that the heart be lowest, he said. For instance, if the foot is the painful, injured site, it should be highest, while the heart should be lowest. “It keeps a lot of the swelling down, and inflammation [from swelling] is a big component of pain,” he said.

Icing is also often done insufficiently. “Patients need more specific instructions,” and while icepacks are often coldest, “they can give you frostbite,” Dr. Spurdle said. He suggests putting ice in a bag with a towel over the skin for protection. He tells patients to ice for 10 to 15 minutes every hour, and individualizes the length of time to continue the remedy on a case-by-case basis. Despite differences in the literature about the effectiveness of this method, Dr. Spurdle said, in his clinical experience, it has made a substantial difference, both short-term for acute pain and long-term for chronic pain.

TENS Makes a Comeback

Transcutaneous electrical nerve stimulation (TENS) units are making a comeback, said Elmer Pinzon, MD, MPH, medical director of the University Spine and Sports Specialists in Knoxville, TN, and an editorial advisor for PPM. While the devices do not work for everyone, they may be worth a try, he said. The small, battery-operated devices deliver low-voltage electrical pulses to the painful area. Prices vary from about $30 to around $100, he said, noting that some are available over-the-counter, but not all are covered by insurance. Dr. Pinzon suggests having patients try a TENS unit as part of a physical therapy setting first before purchasing one.

While published research has produced mixed findings on the efficacy of TENS, in a recent study, researchers concluded that TENS does indeed lead to pain reduction, possibly due to the activation of the descending pain-inhibitory pathway. In the study, patients given a painful stimuli without the TENS unit during the exposure had significantly higher pain and unpleasantness ratings than those given the TENS unit during exposure to the painful stimuli. The researchers administered functional MRI (fMRI) scans to detect brain activity in both those who had and did not have the TENS unit, suggesting that this activation of the pain-inhibitory pathway was key to pain reduction.3

Electrotherapy such as TENS is typically used along with other treatments, and it may help alleviate pain enough for a patient to participate more actively in targeted physical therapy exercises, Dr. Pinzon said. He clarified that TENS units often prove more effective in treating chronic pain than acute pain.

Self-Help, Yoga, and Meditation

Also better for chronic pain than acute pain, yoga may help athletes suffering from neck and back conditions, Dr. Pinzon said. They may experience gains in strength, flexibility, and endurance fairly quickly, he added. In one recent study, experts compared physical therapy with yoga in 320 people who had moderate to severe chronic low back pain and found that yoga was as effective as going to physical therapy.4
