Summary:An abstract of a study by Davi et al comparing measures of arthrogenic muscle inhibition (AMI) in cases of anterior knee pain (AKP) with or without diagnostic evidence of structural patellar tendon (PT) damage to determine whether pain alone contributes to quadriceps AMI is presented. Knees with structural PT damage demonstrated reduced volitional muscle activation and alterations in afferent pathways of AMI. In contrast, knees with only AKP demonstrated levels of quadriceps neural activity that are equal to that of healthy normative values. Taken together, these data lead them to believe that structural damage, potentially originating from altered mechanoreceptors, not pain, is primarily responsible for quadriceps AMI in this population. Continued investigation is needed in order to confirm these relationships but the findings may have important implications for clinical care of athletes suffering knee pain.
