Magnetic resonance imaging findings in painful hemiplegic shoulder patients with or without subluxation: A retrospective cohort study.

The relationship between hemiplegic shoulder pain (HSP) and subluxation is unclear. This study aimed to determine the differences of magnetic resonance imaging (MRI) findings in HSP patients with or without subluxation after stroke, and to analyze the etiology of shoulder pain. This retrospective study included 53 patients with HSP after stroke from September 2013 to February 2020.

Regional brain atrophy in patients with chronic ankle instability: A voxel-based morphometry study.

The objective of this study was to investigate whether brain volume changes occur in patients with chronic ankle instability (CAI) using voxel-based morphometry and assessing correlations with clinical tests. Structural magnetic resonance imaging data were prospectively acquired in 24 patients with CAI and 34 healthy controls. CAI symptoms and pain intensity were assessed using the Foot and Ankle Ability Measure (FAAM), Cumberland Ankle Instability Tool (CAIT), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and visual analog scale (VAS).

Effects of Different Static Progressive Stretching Durations on Range of Motion, Myofibroblasts, and Collagen in a Posttraumatic Knee Contracture Rat Model.

Objective: The purpose of this study was to investigate the effects of different durations of static progressive stretching (SPS) on posttraumatic knee contracture in rats, including range of motion (ROM), gait analysis, myofibroblast proliferation, and collagen regulation.

Methods: The posttraumatic knee contracture model was established, and male Wistar rats were randomly divided into the 20-minute SPS treatment, 30-minute SPS treatment (S30), 40-minute SPS treatment, untreated, immobilization, and control groups. At Week 1, 2, and 4 of treatment intervention, joint ROM and gait were measured and compared.

[Research advances in pathomechanism and treatment of joint contracture].

Joint contracture is one of the common musculoskeletal disorders. It has seriously disturbed patients' activities of daily living in various aspects. The pathogenesis of it is eager to explore to distinct degree.

[The Therapeutic Effect and Mechanism of Static Progressive Stretching in Different Durations on Traumatic Knee Contracture in Rats].

Objective: To investigate the effect and mechanism of static progressive stretching (SPS) in different durations on traumatic knee contracture in rats.

Methods: Seventy male Wistar rats were randomly divided into three groups, including surgical modeling group ( =50), control group (CON, no surgery, no treatment, =10) and trauma without immobilization group (TRA, no treatment, =10). The knee contracture model was established, and 50 surgical modeling rats were randomly divided into five groups including static progressive stretching treatment for 20 minutes group (S20 min, =10), treatment for 30 minutes group (S30 min, =10), treatment for 40 minutes group (S40 min, =10), untreatment group (UNT, no SPS, =10) and modeling group (MOD, =10, euthanized after immobilization for histological staining and Western blot).

Radiofrequency ablation micro-dissecting of eyelid nevus with XL-RFA device under operating microscope.

Aim: To study the effect of an innovative micro-dissection procedure by radiofrequency ablation (MRA) in removing eyelid nevus.

Methods: Fifty-six consecutive outpatients with eyelid nevus were treated with MRA using a monopolar device. The effect of MRA was determined after following-up for 6mo to 5y.

Paclitaxel reduces formation of hypertrophic scars in the rabbit ear model.

Background And Objective: The onset and progression of pathological scarring involves multiple cytokines and complex mechanisms. However, hyperplasia of fibroblasts and neovascularization plays important roles, which can be inhibited by paclitaxel. The aim of this study was to investigate the efficacy of paclitaxel in the treatment of hypertrophic scars on rabbit ears.
