Variations in Observations of Geosynchronous Magnetopause and Last Closed Drift Shell Crossings With Magnetic Local Time by Thomas A. Daggitt, Richard B. Horne, Sarah A. Glauert, Giulio DelZanna, Mervyn P. Freeman

“…Abstract We analyze a set of events in which both electron flux dropouts caused by magnetopause shadowing and geosynchronous magnetopause crossings (GMCs) are observed. These observations are compared to event‐specific last closed drift shell (LCDS) models derived from the TS05 and TS07 external field models and magnetopause standoff distance. …”

Exercise Intervention in Women with Fibromyalgia and Its Influence on Pain, Psychological Variables, and Disability: An Observational Study by María Elena González-Álvarez, Víctor Riquelme-Aguado, Giacomo Rossettini, Josué Fernández-Carnero, Jorge Hugo Villafañe

“…This study aims to examine the effects of a 6-week telerehabilitation combined exercise program—including mobility, strength, and high-intensity exercises—on pain, psychological variables, and disability in women with fibromyalgia. (2) Methods: In this observational study involving 53 FM patients, the outcomes measured were the pressure pain threshold (PPT), the conditioned pain modulation (CPM) paradigm, levels of pain on the measurement day and the average of the last week (using NRS) the impact of the fibromyalgia (using Fibromyalgia Impact Questionnaire (FIQ), and anxiety (using the Spanish version of the State–Trait Anxiety Inventory—STAI). (3) Results: Statistically significant changes were observed in the intervention group in PPT, CPM, NRS, and FIQ. (4) Conclusions: A six-week telerehabilitation therapeutic exercise intervention consisting of two scheduled exercise sessions per week lasting approximately 45 min each is associated with reduced pain levels, enhanced pain inhibitory pathways, and a decreased impact of fibromyalgia compared to patients who do not adopt a more active lifestyle.…”
