Arthrogenic muscle inhibition (AMI) has been observed in this population; however, relationships with injury-related impairments are unclear, potentially due to the resting, prone position in which AMI is typically measured. Assessing AMI during bipedal stance may provide a better understanding of this relationship.</p><p><strong>Methods: </strong>AMI was assessed in 38 young adults (19 ALAS within 72 h of injury: 10 males, 21.4 ± 2.7 years; 19 healthy controls: 10 males, 21.9 ± 2.2 years; mean ± SD) using the Hoffmann reflex (H-reflex) during bipedal stance. Electrical stimulation was administered to identify the maximal H-reflex (H<sub>max</sub>) and maximal motor response (M<sub>max</sub>) from the soleus, fibularis longus, and tibialis anterior muscles. The primary outcome measure was the H<sub>max</sub>/M<sub>max</sub> ratio. Secondary outcomes included acute symptoms (pain and swelling), postural control during bipedal stance, and self-reported function.</p><p><strong>Results: </strong>No significant group-by-limb interactions were observed for any muscle. However, a significant group main effect was observed in the soleus muscle (F<sub>(1,35)</sub> = 6.82, p = 0.013), indicating significantly lower H<sub>max</sub>/M<sub>max</sub> ratios following ALAS (0.38 ± 0.20) compared to healthy controls (0.53 ± 0.16). Furthermore, lower H<sub>max</sub>/M<sub>max</sub> ratios in the soleus significantly correlated with acute symptoms and self-reported function but not with postural control.</p><p><strong>Conclusion: </strong>This study supports previous evidence of AMI in patients with ALAS, providing insight into neurophysiologic impacts of musculoskeletal injury. Our results suggest that assessing AMI in a standing position following acute injury may provide valuable insight into how AMI develops and guide potential therapeutic options to curb and offset the formation of joint instability.</p>","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":" ","pages":"559-568"},"PeriodicalIF":11.7,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11184308/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140013528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
