Background: Female urologists report higher rates of work-related physical discomfort compared to male urologists. We compared ergonomics during simulated ureteroscopy, the most common surgery for kidney stones, between male and female urologists.
Methods: Surface electromyography was used to measure muscle activation during common ureteroscopic tasks in urology trainees and staff with different surgeon positions and ureteroscopes. Subjective workload was assessed using the NASA Task Load Index (NASA-TLX). Paired t-tests, Wilcoxon rank-sum tests, and multivariate regressions were used to compare muscle activation by gender for each trial condition.
Results: There was no difference in age or distribution of training level between genders, though men had larger glove sizes. Across all conditions, women required greater muscle activation in multiple muscle groups and had greater NASA-TLX scores compared to men.
Conclusions: There may be gender differences in ergonomics during ureteroscopy based on muscle activation and subjective workload, suggesting potential for personalizing surgical ecosystems.

The purpose of this study is to evaluate the effectiveness of intensity-modulated radiation therapy (IMRT) combined with periorbital triamcinolone acetonide injection in treating thyroid eye disease (TED) patients with active extraocular muscle but low CAS. The retrospective observational study was conducted. A total of 156 eligible patients were selected from the TED patient database of the Ophthalmology Department of West China Hospital of Sichuan University.

Mares with endometrosis exhibit histological changes not only in the endometrium but also in the myometrium that suggest possible functional impairment. The molecular background of these changes is not well understood. We hypothesize that the transcriptomic profile of the mare myometrium varies depending on the degree of endometrosis in mares.

Objectives: The study aimed to examine the effects of exercise-induced muscle damage on running kinetics.
Design: Twenty-six adult recreational male runners performed 60 min of downhill running (-10 %) at 65 % of maximal heart rate. Running gait changes, systemic and localized muscle damage markers were assessed pre - and post-exercise induced muscle damage protocol.

Objective: This study aimed to validate the ultrasound speckle tracking (UST) algorithm, determine the optimal probe location by comparing normalized cross-correlation (NCC) values of muscle displacement at two locations (proximal vs. middle) of the biceps femoris long head (BFlh) using the UST, and investigate the effects of Nordic hamstring curl exercise (NHE) training on BFlh displacement.
Methods: UST efficacy was verified with ex vivo uniaxial testing of porcine leg muscles.
Single-centre, double-blinded, randomised placebo-controlled trial to determine the effect of a 12-week home-based programme of footplate neuromuscular electrical stimulation on walking capacity in people with peripheral artery disease: a protocol for the Foot-PAD trial.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.
