Background: Quadriceps dysfunction is ubiquitous after anterior cruciate ligament (ACL) reconstruction (ACLR). Addressing quadriceps dysfunction is crucial to improve function, reduce the reinjury risk, and maintain long-term knee health. While deficits specific to the quadriceps are well documented, less is known about the effect of an ACL injury on other lower extremity muscle groups.

Previous literature, on the basis of small sample sizes, concludes that there are several risk factors for the development of PPCS.
Objective: We seek to identify protective and risk factors for developing slow recovery or persisting post-concussion symptoms (PPCS) by analyzing medical history, contact sport level, setting, and the Sport Concussion Assessment Tool (SCAT) and Brief Symptom Inventory (BSI-18) assessments at baseline and post-injury.
Article Synopsis
- This study aims to create a prognostic model to predict recovery times for concussion patients, benefiting early treatment interventions worldwide.
- The research involved analyzing diffusion-weighted MRI data from collegiate athletes who suffered concussions, categorizing recoveries into early and late groups based on their return-to-play timelines.
- Advanced data processing techniques were used to assess microstructural properties of brain tracts, with statistical analyses employed to evaluate their correlation with recovery outcomes, ultimately using logistic regression for classification.
Background: Early medical attention after concussion may minimize symptom duration and burden; however, many concussions are undiagnosed or have a delay in diagnosis after injury. Many concussion symptoms (eg, headache, dizziness) are not visible, meaning that early identification is often contingent on individuals reporting their injury to medical staff. A fundamental understanding of the types and levels of factors that explain when concussions are reported can help identify promising directions for intervention.

Moderate hypoxic exposures, fractions of inspired oxygen (FiO2) of 0.11 to 0.
