Impact of Fatiguing Exercises on Movement Strategies in Chronic Ankle Instability, Lateral Ankle Sprain Copers, and Controls.

While research exists to induce fatigue using isokinetic dynamometers or simple repetition tasks in patients with chronic ankle instability (CAI), there is a lack of research examining landing movement strategies using fatigue protocols that mimic actual sports. Therefore, we aimed to investigate the effects of CAI and fatiguing exercises on the lower-extremity kinematics and kinetics during single-leg drop landings among patients with CAI, lateral ankle sprain (LAS) copers and controls. A cross-sectional study recruited 20 patients with CAI, 20 LAS copers, and 20 controls in a biomechanics laboratory.

How Medial Tibial Stress Syndrome Is Affected by Alignment, Range of Motion, Strength, and Gait Biomechanics: A Systematic Review and Meta-Analysis.

Context: Medial tibial stress syndrome (MTSS) is a common chronic injury of the lower-extremity in the physically active population. However, the risk factors for MTSS remain unclear.

Objective: This study identified the risk factors for MTSS and established the continuum model of lower-extremity alignments, range of motion, muscular strength, and gait kinematics affecting each other and MTSS development.

Stroke walking and balance characteristics via principal component analysis.

Balance impairment is associated gait dysfunction with several quantitative spatiotemporal gait parameters in patients with stroke. However, the link between balance impairments and joint kinematics during walking remains unclear. Clinical assessments and gait measurements using motion analysis system was conducted in 44 stroke patients.

Effects of community ambulation training with 3D-printed ankle-foot orthosis on gait and functional improvements: a case series of three stroke survivors.

Introduction: Many of the patients using ankle-foot orthoses (AFOs) experience poor fit, pain, discomfort, dislike of the aesthetics of the device, and excessive range of motion restrictions, which diminish the use of AFOs. Although 3D-printed ankle-foot orthoses (3D-AFOs) affect patient satisfaction and overall gait functions such as ankle moment, joint range of motion (ROM), and temporal-spatial parameters, the material properties and manufacturing process of 3D-AFOs are still diverse; the clinical effects of community ambulation using 3D-AFOs and satisfaction in patients with stroke are poorly understood.

Case Description: Case 1: A 30-year-old man, with a history of right basal ganglia hemorrhage, presented with marked foot drop and genu recurvatum.

Mechanisms of Sports Concussion in Taekwondo: A Systematic Video Analysis of Seven Cases.

Sports-related traumatic brain injuries are the most common injury in adolescents and young adults due to recurrent concussion experiences and head shock. Therefore, this study was designed to describe player characteristics and situational factors associated with concussions in the World Taekwondo Championships using systematic video analysis. Athlete injury data were collected using a web-based injury surveillance system at the World Taekwondo Championships organized by World Taekwondo from 2017 to 2019.

Altered Biomechanics in Individuals With Chronic Ankle Instability Compared With Copers and Controls During Gait.

Context: Given that motions of 1 segment affect those of an adjacent segment, the authors of biomechanical studies must thoroughly investigate the kinematics and kinetics of the proximal joints (hip and knee) as well as the ankle joints in patients with chronic ankle instability (CAI). However, few researchers have investigated the altered movement strategies of the lower extremities of patients with CAI compared with lateral ankle-sprain (LAS) copers and control participants throughout the full gait cycle of walking and jogging.

Objective: To evaluate lower extremity biomechanical differences in patients with CAI, LAS copers, and control individuals during gait.

Alterations of lower extremity function, health-related quality of life, and spatiotemporal gait parameters among individuals with chronic ankle instability.

Objective: To identify differences in patient-reported outcome questionnaires and spatiotemporal gait parameters during walking between individuals with and without chronic ankle instability (CAI) and to identify relationships between patient-oriented outcome and spatiotemporal gait parameters.

Participants: Twenty-four individuals with CAI and 24 controls were included in this study.

Main Outcome Measures: All participants completed the Foot and Ankle Ability Measure including the Activities of Daily Living and Sport Subscales, the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), the Lower Extremity Functional Scale, and the Korean version of the EuroQol 5-Dimension (KEQ-5D).

Ankle Instability Patients Exhibit Altered Muscle Activation of Lower Extremity and Ground Reaction Force during Landing: A Systematic Review and Meta-Analysis.

This review aimed to investigate characteristics of muscle activation and ground reaction force (GRF) patterns in patients with ankle instability (AI). Relevant studies were sourced from PubMed, CINAHL, SPORTDiscus, and Web of Science through December 2019 for case-control study in any laboratory setting. Inclusion criteria for study selection were (1) subjects with chronic, functional, or mechanical instability or recurrent ankle sprains; (2) primary outcomes consisted of muscle activation of the lower extremity and GRF during landing; and (3) peer-reviewed articles with full text available, including mean, standard deviation, and sample size, to enable data reanalysis.

Injury and Illness in World Taekwondo Junior Athletes: An Epidemiological Study.

Taekwondo has been reported to be one of the most injurious sports in the summer Olympics, however, there is a dearth of data about injury profiles for junior athletes. Therefore, we aimed to identify the incidence and profiles of the injuries and illnesses that occurred during the 2018 World Taekwondo Junior Championships and recorded using an online system. Among the 889 athletes, 67 injuries and four illnesses were reported, corresponding to an overall clinical incidence of 7.

Can Neurocognitive Function Predict Lower Extremity Injuries in Male Collegiate Athletes?

The purpose of this study is to demonstrate whether neurocognitive evaluation can confirm the association between neurocognitive level and postural control and to analyze the relationship between neurocognitive level and acute musculoskeletal injury in male non-net sports athletes. Seventy-seven male non-net sports athletes participated in this study. The Standardized Assessment of Concussion (SAC), Landing Error Scoring System (LESS), Balance Error Scoring System (BESS), and Star Excursion Balance Test (SEBT) were used for testing; we collected data related to injury history for six months after testing.
