Individuals Following Anterior Cruciate Ligament Reconstruction Respond Differently To Limb Loading Instruction: A Clustering Analysis, Willa Ma, Susan Sigward
Individuals Following Anterior Cruciate Ligament Reconstruction Respond Differently To Limb Loading Instruction: A Clustering Analysis, Willa Ma, Susan Sigward
International Journal of Exercise Science: Conference Proceedings
Individuals following anterior cruciate ligament reconstruction (ACLr) demonstrate altered loading strategies such as shifting mechanical demand away from the surgical knee. Previous work found that individuals can restore limb loading symmetry with instruction to equalize weight distribution between limbs during a squat task. However, when looking at individual responses to these instructions, it appear that not all individual responded similarly. PURPOSE: To use k-means clustering to describe the variation in response to instruction to equalize weight between limbs in individuals 3-4 months post-ACLr. METHODS: We performed a secondary analysis of a dataset including two groups: individuals 110.4 days …

Altered Cortical Activation Patterns In The Motor Cortex Post Acl Reconstruction Compared To Healthy Control, Ryan Kim, Lana Kayali, Abi Rae Stine, Yong Woo An Facsm

Following anterior cruciate ligament reconstruction (ACLR), patients often experience persistent knee dysfunction, such as knee strength deficit, possibly correlated with altered cortical activation in the brain. However, it remains unclear if ACLR patients exhibit different cortical activation patterns in the primary motor cortex (M1) during strength tasks, when compared to healthy control. PURPOSE: To examine electrocortical activation patterns in the M1 during submaximal isometric contraction of the quadriceps between an ACLR patient and a healthy control. METHODS: Both ACLR (female, 21yrs,180.34cm, 77.11kg) and control (female, 39yrs, 160.02cm, 61.23kg) performed isometric extension of the reconstructed or matched knees at …
