Article Synopsis
- Athletes at risk for ACL injuries often have issues with visual cognitive function and brain connectivity related to motor skills.
- This study tested a training method called visual perturbation neuromuscular training (VPNT) to see if it could enhance physical and cognitive demands, improve landing safety, and decrease neural activity for knee control.
- Results showed that VPNT led to better landing mechanics and reduced brain activity in key areas, suggesting it can effectively improve athletic performance and may pave the way for more thorough studies in the future.
Article Synopsis
- Yohimbine is an alpha-2 adrenoreceptor antagonist commonly used in supplements for libido, erectile dysfunction, and weight loss, but can cause toxicity leading to serious health issues like intracranial hemorrhage (ICH).
- A case study describes a 39-year-old woman who experienced severe symptoms including high blood pressure and neurological damage after taking a supplement containing yohimbine, resulting in hospitalization and rehabilitation.
- The patient's pre-existing conditions, including chronic clonidine use and other medications, likely heightened her risk for severe reactions to yohimbine, though it's unclear if yohimbine was definitively responsible for her ICH due to lack of confirmatory testing.
Context: Proprioception is an individual's awareness of body position in 3-dimensional space. How proprioceptive acuity changes under varying conditions such as joint position, load, and concentric or eccentric contraction type is not well understood. In addition, a limitation of the variety of techniques to assess proprioception is the lack of clinically feasible methods to capture proprioceptive acuity.

While neural activity associated with upper extremity force control has been documented, extrapolation to lower extremity force control is limited. Knowledge of how the brain regulates force control for knee extension and flexion may provide insights as to how pathology or intervention impacts central control of movement.
