Bridging the Gap: What Athletic Trainers Know About AMI
Arthrogenic muscle inhibition (AMI) is a common but often under-addressed consequence of joint injury. This neurophysiological condition limits muscle activation around the injured joint, contributing to prolonged weakness and impaired recovery. As a condition regularly encountered in athletic training practice, AMI demands attention not only from researchers but also from clinicians on the front lines of rehabilitation.
Our 2021 study, "Understanding Athletic Trainers’ Knowledge, Intervention, and Barriers Toward Arthrogenic Muscle Inhibition," explored how athletic trainers (ATs) approach this critical issue. The findings revealed both strengths and gaps in clinical practice, pointing to opportunities for improvement in education, resources, and application of evidence-based interventions.
Key Findings from the Study
Knowledge of AMI:
Over two-thirds of surveyed ATs correctly defined AMI and understood its mechanisms, such as joint effusion and altered joint receptor activity.
However, gaps remain in recognizing the long-term consequences of untreated AMI, such as chronic muscle weakness and impaired neuromuscular control.
Clinical Interventions:
Disinhibitory interventions like neuromuscular electrical stimulation (NMES), transcutaneous electrical nerve stimulation (TENS), and focal joint cooling were the most commonly used evidence-based treatments.
Misuse of these interventions was common, with timing often inconsistent with evidence—for example, applying cooling after exercise instead of before, where it would have a greater disinhibitory effect.
Barriers to Effective Treatment:
The top barriers included difficulty quantifying AMI in clinical settings and lack of education on appropriate interventions.
ATs who didn’t use disinhibitory interventions were more likely to perceive barriers like limited knowledge, time, and access to therapeutic modalities.
What This Means for Athletic Trainers
These findings underscore a need for enhanced education and training on AMI, particularly on the timing and application of interventions. Simple adjustments, like using focal joint cooling or TENS before exercise, could significantly improve patient outcomes. Additionally, better tools to quantify AMI in real time could empower ATs to track progress and tailor treatments more effectively.
Moving Forward: A Call to Action
For ATs and other clinicians, understanding AMI isn’t just about solving a clinical puzzle—it’s about giving patients the best chance at a full recovery. Here’s how we can make a difference:
Improve Education: Incorporate AMI-specific content into athletic training curricula and continuing education programs.
Apply Evidence: Ensure that interventions align with current research, optimizing timing and technique to maximize benefits.
Expand Access: Advocate for affordable, widely available tools to identify and treat AMI effectively.
By bridging the gap between research and practice, we can empower athletic trainers to address AMI head-on, improving outcomes for athletes and active individuals alike.
