AI Article Synopsis
- The study examined the link between how individuals with fibromyalgia (FM) perceive their physical function and their actual physical and cognitive abilities, using objective tests.
- Conducted in Southern California, it involved 68 adults who met the criteria for FM and utilized various assessment measures, including balance and cognitive tests.
- Results showed that better performance in physical tests correlated with higher cognitive abilities, suggesting that physical activity may positively impact brain function; further research is recommended to understand underlying mechanisms.
Article Abstract
Objective: To investigate the associations between perceived physical function (self-report) and physical and cognitive performance (objective assessments) in persons with fibromyalgia (FM).
Design: Correlational study.
Setting: Exercise testing laboratory in Southern California.
Participants: Community-residing ambulatory adults meeting the American College of Rheumatology 1990 criteria for FM (N=68; mean age, 59.5y).
Interventions: Not applicable.
Main Outcome Measures: Composite Physical Function scale, Senior Fitness Test (3 items), Fullerton Advanced Balance scale, 30-foot walk, Trail Making Test parts A and B, Digit Symbol Substitution Test, a composite score of these 3 cognitive measures, attention/executive function composite, processing speed composite, problem solving, inhibition, and episodic memory composite.
Results: Hierarchical regression analyses showed that after controlling for age and FM symptoms, better physical performance (based on assessments, not self-report) was associated with higher cognitive function in attention/executive function, processing speed, problem solving, and inhibition.
Conclusions: Researchers should continue to investigate the relationship between physical and cognitive function in both clinical and nonclinical populations, as well as explore changes across time. Because physical activity has been associated with neural improvements, further research may identify whether particular mechanisms, such as neurogenesis, synaptogenesis, or changes in inflammatory marker levels, are involved.

Background: Young adults are in the period of the formation and establishment of values. Even though previous research has revealed that personal values are important factors influencing young adults' life satisfaction, it is still unknown when and under what circumstances values affect life satisfaction among young adults. Therefore, this study explored the relationship between personal values and life satisfaction among Chinese young adults, focusing on the mediating roles of resilience and emotional intelligence.

Attention deficit/hyperactivity disorder (ADHD) is characterized by inattention, hyperactivity, and impulsivity, as children may present developmental and chronic impairments in cognitive-emotional and sensory-motor aspects. This study examined the changes in self-efficacy, muscle tone, and mood following a single session of Equine-Assisted Occupational Therapy (EAOT) within Attention Skills Therapy (ASTride) intervention, designed to improve emotional and cognitive functions. Notably, 31 children diagnosed with ADHD aged 6-12 (mean age 10.
