To identify the single leg balance (SLB) test that discriminates among healthy, coper, and chronic ankle instability (CAI) groups and to determine effects of ankle muscles on the balance error scoring system (BESS) among the three populations. 60 subjects (20 per group) performed the SLB test with eyes open (EO) and eyes closed (EC). Normalized mean amplitude (NMA) of the tibia anterior (TA), fibularis longus (FL), and medial gastrocnemius (MG) muscles and BESS were measured while performing the SLB test. The coper group had a lower error score than the CAI group in the EC...

Previous studies have investigated how additional arm weights affect gait. Although light weights (0.45 kg) seemed to elicit performance improvements in Parkinsonian patients, it was not studied how light weights affect gait parameters in healthy individuals. It is important to understand normal responses in a healthy population so that clinical effects might be better understood. Therefore, the purpose of this study was to investigate the effects of arm weights on arm swing amplitude, gait performance, and muscle activity in healthy people...

INTRODUCTION: Shoulder pain is highly prevalent in competitive swimmers, and generalized joint hypermobility (GJH) is considered a risk factor. Sensorimotor control deficiencies and altered neuromuscular activation of the shoulder may represent underlying factors. RESEARCH QUESTION: To investigate whether competitive swimmers with GJH including shoulder hypermobility (GJHS) differ in shoulder sensorimotor control and muscle activity from those without GJH and no shoulder hypermobility (NGJH)...

CONTEXT:   Anterior cruciate ligament (ACL) reconstruction (ACLR) is the most commonly used method for helping athletes regain function and return to preinjury activity levels after ACL injury. Outcomes after ACLR have suggested that athletes return to a level of function that would support a return to sport participation; however, in a recent meta-analysis, pooled return rates were only 55%. It is unclear whether this discrepancy is a result of functional impairments. OBJECTIVE:   To compare patient-reported outcomes (PROs), dynamic balance, dynamic functional performance, strength, and muscular endurance in athletes who have returned to sport (RTS) and athletes who have not returned to sport (NRTS) after ACLR...

OBJECTIVE The transpterygoid extension of the endoscopic endonasal approach provides exposure of the petrous apex, Meckel's cave, paraclival area, and the infratemporal fossa. Safe and efficient localization of the lacerum segment of the internal carotid artery (ICA) is a crucial part of such exposure. The aim of this study is to introduce a novel landmark for localization of the lacerum ICA. METHODS Ten cadaveric heads were prepared for transnasal endoscopic dissection. The floor of the sphenoid sinus was drilled to expose an extension of the pharyngobasilar fascia between the sphenoid floor and the pterygoid process (the pterygoclival ligament)...

Prior studies of functional connectivity following callosotomy have disagreed in the observed effects on interhemispheric functional connectivity. These connectivity studies, in multiple electrophysiological methods and functional MRI, have found conflicting reductions in connectivity or patterns resembling typical individuals. The authors examined a case of partial anterior corpus callosum connection, where pairs of bilateral electrocorticographic electrodes had been placed over homologous regions in the left and right hemispheres...

Transcatheter mitral valve implantation (TMVI) has been performed in high-risk and inoperable patients for degenerated mitral bioprostheses (TMVIinV) and failed annuloplasty rings (TMVIinR). TMVIinR is more challenging compared to TMVIinV because of the differences in dimensions, shapes, and contours between rings and valves. In this report, we present two clinical cases of TMVIinR that were treated by trans-septal implantation of a balloon-expandable prosthesis. In TMVI cases with an incomplete ring, the ring will be stretched out toward its anterior and commissural side, and the open side of the ring will increase in width...

Due to different disease background of gastric stump cancer(GSC) patients (benign or malignant lesion, reconstruction of digestive tract, etc.), the GSC surgical procedure and the difficulty of lymphadenectomy are also different. The extent of radical lymphadenectomy for gastric stump cancer should extend beyond D2 lymphadenectomy, according to the different backgrounds of initial disease, reconstructions, and tumor location. A lymphadenectomy should include the lymph nodes in anterior (No.17) and posterior (No...

INTRODUCTION AND OBJECTIVE: Robot-assisted sacral colpopexy (RASC) is a fast growing approach for surgeons treating patients with advanced stage pelvic organ prolapse (POP). Open abdominal sacral colpopexy has been the gold standard for advanced POP but requires longer hospital stays and a much larger incision. The indications, preoperative preparation, operative positioning, and operative steps are detailed, and an accompanying video shows the approach. METHODS: RASC can be broken down into 11 steps and the reader will be able to reference the article to the corresponding portion of the video...

AIM: Echo-planar imaging is a common technique used in functional magnetic resonance imaging (fMRI), however it suffers from image distortion and signal loss because of large susceptibility effects that are related to the phase-encoding direction of the scan. Despite this relationship, the majority of neuroimaging studies have not considered the influence of phase-encoding direction. Here, we aimed to clarify how phase-encoding direction can affect the outcome of an fMRI connectivity study of schizophrenia...

PURPOSE OF REVIEW: Treatment of anterior urethral stricture disease (USD) has shifted from endoscopic approaches to urethroplasty with significantly higher success rates among reconstructive urologists. This academic stance has led to a critical evaluation of "success" and developing disease-specific instruments to assess surgical outcomes focusing on patients' satisfaction rather than the historical goal of avoiding secondary procedures. RECENT FINDINGS: Many disease non-specific and/or non-validated patient-reported outcome measures (PROMs) have been utilized to evaluate the voiding symptoms and sexual of function of patients after urethroplasty in the literature...

Early identification of bulbar involvement in persons with ALS is critical for improving diagnosis and prognosis; however, efficacious diagnostic markers have not yet been identified. The purpose of this study was to determine whether kinematic changes of the tongue and jaw during swallowing, measured using 3D electromagnetic articulography (EMA), predate clinically identifiable symptoms of speech and swallowing impairment in persons diagnosed with ALS. Data were collected from 16 adults diagnosed with ALS and 18 neurotypical controls...
