Purpose: Identifying risk factors for breast cancer-related lymphedema (BCRL) is crucial for its prevention, necessitating large-scale epidemiological studies. Despite their suitability for large-scale surveys, to our knowledge, databases have not been the basis of any study done to investigate BCRL risk factors. This study aimed to test the hypothesis that a database-based study would be useful for identifying BCRL risk factors.

- High-density surface electromyography (HD-sEMG) is used to analyze motor unit activity in the suprahyoid muscles of Parkinson's disease (PD) patients, focusing on muscle recruitment and action potential changes.
- This study involved measuring electrical activity during tongue elevation in both PD patients and healthy controls, assessing various metrics, and evaluating the effects of cervical percutaneous interferential current stimulation over 8 weeks.
- Results indicate that PD patients had lower muscle activation compared to controls, but stimulation improved some muscle activity metrics, suggesting HD-sEMG is a valuable tool for studying swallowing-related issues in PD.
Article Synopsis
- The study investigates the mechanisms behind chronic knee osteoarthritis pain and pain after knee surgery, focusing on brain connectivity, specifically involving the anterior insular cortex (aIC).
- Fifteen patients with knee osteoarthritis underwent magnetic resonance imaging and clinical assessments before and six months after knee arthroplasty, along with 15 matched control patients for comparison.
- Results revealed that changes in resting-state functional connectivity (rs-FC) between the aIC and specific brain regions correlated with pain levels, suggesting that rs-FC may help understand knee OA and postoperative pain.

Objective: Muscle fatigue contributes to anterior cruciate ligament (ACL) injuries, with increased knee and hip abduction observed during fatigue. However, there have been no reports revealing the differences between fatigue tasks or the duration of these changes. In this study, we conducted single-leg drop landings before and after hip and knee fatigue tasks to elucidate the changes in lower limb biomechanics over time.

The incidence of silent aspiration is high in such patients owing to decreased pharyngeal and laryngeal sensation; thus, interventions for this condition may help prevent pneumonia. In this single-arm, open-label study, we used a cervical percutaneous interferential current stimulation device to activate pharyngeal and laryngeal sensory nerves.
