Influencer prescription: Why TikTok and AI can’t replace sports medicine expertise

If you spend any time scrolling through TikTok, Instagram, or YouTube, you have probably seen them: confident creators demonstrating the “one exercise” that fixed their knee pain or eliminated their back pain.

When you are frustrated by an injury, a simple answer is appealing. Unfortunately, human anatomy is rarely as simple as a 30-second video suggests.

When views start looking like credentials

Social media allows athletic trainers, physical therapists, and physicians to share valuable education. The problem begins when popularity starts to look like expertise.

Someone can accumulate millions of followers without having the education, training, or credentials to provide medical advice. High view counts do not equal accuracy, and a comment section filled with “this worked for me” does not make a treatment safe or appropriate for you.
Algorithms are designed to keep you watching, not to determine whether the information is medically appropriate.

The “one exercise” problem

Imagine you are a recreational runner with knee pain searching online for solutions. One creator advocates glute strengthening, another suggests stretching, and a third claims KT tape is the ultimate fix. Which one is correct? The reality is: maybe one, or maybe none.
Knee pain is a symptom, not a diagnosis. Two runners can feel similar pain in the exact same spot for entirely different reasons. Taping or stretching might offer temporary relief, but it will not uncover why the knee hurts or whether continuing to run could make the problem worse.
A clinical evaluation helps fill this gap. A sports medicine professional considers your health history, movement patterns, strength, previous injuries, and activity demands. The key question should never be, “What exercise fixed someone else’s pain?” It should be, “Why does this specific intervention make sense for my injury?”

Now add AI to the equation

Artificial intelligence introduces another dynamic to self-diagnosis. AI chatbot agents can be useful for explaining medical terminology, summarizing general concepts, and helping you prepare for a conversation with your healthcare provider.
However, there is a fundamental boundary between information and evaluation. You can tell an AI, “My shoulder hurts when I lift,” and receive an impressive list of possible causes. But technology cannot perform a hands-on physical exam, accurately test your strength, or observe your movement firsthand. AI can also provide information that sounds confident and convincing while being incomplete or incorrect.
AI can help you ask better questions; it cannot replace the clinician evaluating the answers.

Parents, this one is for you

For young athletes, whether running cross country, playing club soccer, or competing under the Friday night lights here in Las Cruces, the stakes can be even higher. Teenagers have unprecedented access to sports advice, often learning how to manage injuries from unverified influencers.
We cannot monitor every video our kids see, but we can teach young athletes to evaluate content critically. Before trying an online solution, ask: Who is offering this advice, and what are their credentials? What evidence supports the claim? Could this exercise be harmful if my injury is different? Most importantly, have they discussed the issue with an athletic trainer, physical therapist, physician, or parent?
If an injury involves significant swelling, an inability to bear weight, obvious deformity, numbness or weakness, or worsening pain, that is not the time to experiment with an online solution. It is time to seek professional evaluation.

Your feed isn’t your athletic trainer

Exploring health concepts online can be valuable when approached with critical thinking. The key is recognizing the difference between general education and individualized care.
Your phone can show you an exercise, but it cannot evaluate your injury. A TikTok video can show someone else’s recovery, but it cannot confirm your injury is the same. AI can generate possibilities, but it cannot perform a physical assessment.
Use social media and AI to start the conversation, not replace it. If a video catches your eye, bring the question to a qualified sports medicine professional. Whether training for a race or staying active in the Mesilla Valley, your health deserves more than an algorithm’s best guess.
Your health isn’t a trend.
Expertise still matters.
