Individuals with rotator cuff tears unsuccessfully treated with exercise therapy have less inferiorly oriented net muscle forces during scapular plane abduction

Luke T. Mattar, Arash B. Mahboobin, Adam J. Popchak, William J. Anderst, Volker Musahl, James J. Irrgang, Richard E. Debski

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

The effects of peeling on finite element method-based EEG source reconstruction

Santtu Soderholm, Joonas Lahtinen, Carsten H. Wolters, Sampsa Pursiainen

Summary: The problem of reconstructing brain activity from electric potential measurements is challenging due to the ill-posed inverse problem and inaccuracies in the utilized forward solution methods. This study investigates the impact of source location restriction on the accuracy of two inverse methods, sLORETA and Dipole Scan, in different signal-to-noise ratios. The findings demonstrate that peeling can significantly enhance the regularity of reconstructed distributions when appropriate depth and low noise level are selected. The applied inverse algorithm and observed brain compartment also influence the accuracy.

Multimodal coupling and HRV assessment characterize autonomic functional changes in congestive heart failure patients with sinus rhythm or severe arrhythmia

Deshan Ma, Li Li, Wenbin Shi, Mengwei Li, Jian Zhang, Yong Fan, Yu Kang, Xiu Zhang, Pengming Yu, Qing Zhang, Zhengbo Zhang, Chien-Hung Yeh

Summary: Autonomic nervous system dysfunction is a significant characteristic of congestive heart failure patients. This study introduced HRV and MMCA-derived parameters to quantify ANS function in CHF patients and compared their clinical efficacy. The results showed that most parameters improved after treatment in SRHF patients, while only a few showed significant differences in ARHF patients. PNS function and ANS balance were recovered in all CHF patients after treatment. These metrics can be used for prognosis and therapeutic efficacy monitoring.

Medical image fusion method based on saliency measurement improvement and local structure similarity correction

Qing Pan, Yunhang Li, Nili Tian

Summary: Medical image fusion is an important tool in medical diagnosis. This paper proposes a medical image fusion method based on saliency measurement improvement and local structural similarity correction. The method decomposes the source images using multi-level decomposition and nonsubsampled shearlet transformation, and then improves the saliency measurement of the base layer fusion rule using the source image mask. Furthermore, a correction method based on structural similarity index measure is used to deal with information distortion. Experimental results show that the proposed method has excellent subjective visual effects and outperforms other state-of-the-art methods in objective indexes.

Binarized spiking neural network optimized with momentum search algorithm for fetal arrhythmia detection and classification from ECG signals

Deepika Shekhawat, Deevesh Chaudhary, Ashutosh Kumar, Anju Kalwar, Neha Mishra, Dimpal Sharma

Summary: Diagnosing fetal cardiac abnormalities by fetal electrocardiogram (FECG) is challenging but crucial. Fetal ECG monitoring provides accurate information on the fetal state. However, the noisy and artifact-ridden ECG signals make ECG extraction difficult. Misdiagnosis of fetal arrhythmias can lead to inappropriate treatment and further complications. This paper proposes a Binarized spiking neural network optimized with Momentum search algorithm for Fetal Arrhythmia Detection and Classification. The proposed technique accurately classifies the output as normal or arrhythmia and outperforms existing approaches.
