Article Abstract
Background: Catheter ablation (CA) can improve exercise tolerance and quality of life (QOL) in patients with atrial fibrillation (AF). However, its differential effects on muscle strength between paroxysmal AF (PAF) and nonparoxysmal AF (Non-PAF) remain unclear.
Methods: We evaluated 94 patients (67.8 ± 10.3 years old, 71% male) who underwent CA (PAF/Non-PAF 46/48) without AF recurrence. Six-minute walk distance (6MWD), leg strength, and an AF-specific QOL questionnaire (AFQLQ) were evaluated at baseline, 3, and 6 months after CA.
Results: At baseline, the 6MWD and AFQLQ subset 3 score were significantly lower in patients with PAF than in those with Non-PAF, but the parameters of muscle strength were comparable between the two groups. Both 6MWD and AFQLQ significantly improved at 6 months after CA in both groups. However, leg strength at 6 months after CA significantly improved in the Non-PAF group (54.9 ± 16.5 to 58.4 ± 15.2, < .05) but not in the PAF group.
Conclusion: Successful CA for both PAF and Non-PAF improved QOL and exercise tolerance. Additionally, CA improved leg strength in Non-PAF patients.

Electrical impedance myography captures features of muscle structure measured by MRI and transcriptomic analysis in facioscapulohumeral muscular dystrophy.

Background: Electrical impedance myography (EIM) has been proposed as an efficient, non-invasive biomarker of muscle composition in facioscapulohumeral muscular dystrophy (FSHD).
Objective: We investigate whether EIM parameters are associated with muscle structure measured by magnetic resonance imaging (MRI), muscle histology, and transcriptomic analysis as well as strength at the individual leg muscle level.
Methods: We performed a multi-center cross-sectional study enrolling 33 patients with FSHD.

It is unknown how knee osteoarthritis pain affects joint power distribution while cycling. The study purposes were to (1) investigate if seat height, workload and any difference in hip or knee extensor strength affected asymmetry of hip, knee and ankle joint power during cycling; and (2) determine the relationship between knee osteoarthritis pain asymmetry and joint power asymmetry at the hips, knees, ankles and total leg. Asymmetry was the difference between dominant and non-dominant legs.
