Assessment of foot posture, morphology, intersegmental mobility, strength and motor control the ankle-foot complex are commonly used clinically, but measurement properties many assessments unclear.To determine test-retest inter-rater reliability, standard error measurement, minimal detectable change joint excursion play, strength, complex.Reliability study.24 healthy, recreationally-active young adults without history injury were assessed by two clinicians on occasions, three to ten days...

Running biomechanics have traditionally been analyzed in laboratory settings, but this may not reflect natural running gait. Wearable sensors offer an alternative.A concurrent validation study to determine agreement between the RunScribeTM wearable sensor (triaxial accelerometer and gyroscope) 3D motion capture system was conducted. Twelve injury-free participants (6 males, 6 females; age = 23.1 ± 5.5 years, weekly mileage 16.1 9.3) ran 1.5 miles on a treadmill. Ten consecutive strides from...

Running biomechanics research has traditionally occurred in the laboratory, but with advent of wearable sensors measurement running may shift outside laboratory. The purpose was to determine if RunScribe™ could detect differences kinematic, kinetic and spatiotemporal measures during runs at two speeds on different surfaces. Fifteen recreational runners (7 males, 8 females; age = 20.0 ± 3.1 years) participated. While wearing heels their shoes, participants completed four 1600 m both track...

The primary sources of injuries in the workplace are improper manual material handling (MMH) motions, forklift collisions, slip, and fall. This research presents a Digital Twin (DT) framework to analyze fatigue humans while performing lifting MMH activity laboratory environment for purpose reducing these types injuries. proposed methodology analyzes worker's body joints detect biomechanical as factor change back, elbow, knee joint angles. Using dynamic time warping (DTW) algorithm, angles...

Context : Kinesiophobia is a substantial psychological factor that may impact sport performance and activities of daily living for individuals with chronic ankle instability (CAI). The purpose this study was to determine the levels kinesiophobia between collegiate athletes nonathletes without CAI using quantitative qualitative analyses. Design Cross-sectional survey. Methods A Qualtrics survey distributed college students. Ankle health status evaluated Foot Ability Measure Sport subscale,...

Background: Variations in ankle injury rates and distributions among competition levels are unclear, but such data may help inform strategies to prevent sprains during American football. Purpose: To describe the epidemiological patterns of youth, high school (HS), collegiate Study Design: Descriptive study. Methods: Data regarding HS, college football athletes were collected from 3 surveillance programs: (1) Youth Football Safety (YFSS), (2) National Athletic Treatment, Injury Outcomes...

Our purpose was to analyze the effects of 4 weeks visual gait biofeedback (GBF) and impairment‐based rehabilitation on biomechanics patient‐reported outcomes (PROs) in individuals with chronic ankle instability (CAI). Twenty‐seven CAI participated this randomized controlled trial (14 received no (NBF), 13 GBF). Both groups 8 sessions rehabilitation. The GBF group reduce frontal plane angle at initial contact (IC) during treadmill walking. NBF walked for equal time but without biofeedback....

Context Exercise-related lower leg pain (ERLLP) is common in runners. Objective To compare biomechanical (kinematic, kinetic, and spatiotemporal) measures obtained from wearable sensors as well extremity alignment, range of motion, strength during running between runners with those without ERLLP. Design Case-control study. Setting Field laboratory. Patients or Other Participants Of 32 young adults who had been regularly (>10 mi [16 km] per week) for ≥3 months, 16 ERLLP ≥2 weeks were...

The purpose of this study was to assess the effects stroke rate and sex on trunk shoulder kinematics Olympic athletes during rowing an ergometer. Fifty-eight participants (31 females 27 males) from Chinese National Rowing Team were recruited. Trunk (i.e., pelvis, lumbar thoracic spine) measured using inertial measurement unit system for three rates (18, 26, 32 strokes/min). Range motion angles at catch finish assessed mixed model ANOVA correlation analyses with power. increased significantly...

This research presents a digital twin concept and prototype to represent human operators in the material handling industry. To construct twin, we use simulation-based framework for data collection analysis. The consists of three modules: Data Collection Module, Operator Analysis Feedback Module Digital Twin Module. A motion capture system assists development which captures simulated activities, similar those take place an actual environment. paper outlines processes involved summarizes...

This study examined lower extremity joint kinematics in individuals with chronic ankle instability (CAI) and controls during unanticipated anticipated single-leg drop landings onto a laterally inclined platform. Physically active adults CAI 15 (n = 15) performed an 30 cm landing 20° Three-dimensional ankle, knee hip-joint were recorded 200 ms pre- to post-landing analysed 2 (group) × (landing condition) SPM ANOVA (p < 0.05). Results revealed displayed significantly greater internal rotation...

Limited evidence exists comparing running biomechanics between individuals with chronic ankle instability (CAI) and those who fully recover (copers). The purpose of this study was to simultaneously analyse gait kinematics, kinetics, surface electromyography (sEMG) sprain copers CAI. Twenty-six (13 CAI, 13 Coper) recreationally active females participated ran shod on an instrumented treadmill at 2.68 m/s. We assessed lower extremity kinematics kinetics sEMG amplitude for the fibularis longus,...

To evaluate the effects of ankle taping, bracing, and fibular reposition taping (FRT) on running biomechanics as measured with wearable sensors.A randomized crossover study design was employed 12 young adults (six males, six females) history sprain completed four 400 m runs at self-selected pace an outdoor track. One conditions (control, taped, braced, FRT) applied prior to each run. RunScribe™ sensors were heel-mounted shoe kinematic (maximum pronation velocity, excursion), kinetic (braking...

Ankle sprains result in pain and disability. While factors such as body mass prior injury contribute to subsequent injury, the association of number ankle on anthropometrics self-reported function are unclear this population. Therefore, purpose investigation was assess differences anthropometric measurements between utilizing a large, pooled data set.Cross-sectional.Data were from 14 studies (total N = 412) collected by Chronic Instability Outcomes Network.
