The condition associated with number symptoms, such as impaired range motion and anxiety. A wide methods for determining the volume lymphedematous arm have been described. Circumference measurement (CM) commonly used in clinics appraise volume, while water displacement (WD) often studies. aim study was assess performance new method using 3D-technology comparison CM WD....

Wearable sensors are increasingly used to provide objective quantification of spatiotemporal and kinematic parameters post-stroke. This study aimed evaluate the practical value sensor-based gait reports in delivering augmented feedback informing development home training programmes following a 2-week supervised intensive intervention after stroke. Four patients with chronic stroke were assessed on four occasions (pre- post-intervention, 3-month, 6-month follow-ups) using clinical tests,...

Abstract Background/Introduction With cardiovascular disease (CVD) constituting a common factor of death, prevention is important. Public health research for and risk management as well digital twins require access to vast amounts longitudinal population data in multiple domains. Due the sensitive nature electronic records (EHR) such poses privacy concerns even coded samples [1,2]. The use cross-sectional synthetic has been proposed alleviate sharing medical data, instance utilising...

Abstract Background/Introduction Cardiovascular diseases (CVDs) are the leading cause of death worldwide, with atherosclerosis being a major contributor. Early detection carotid artery plaques is crucial for CVD prevention and management. While ultrasound imaging widely used, its manual analysis time-consuming prone to variability. Automating plaque deep learning can improve diagnostic consistency efficiency. Recent advancements in unsupervised anomaly models offer promising approach detect...

This paper presents an assessment tool for objective neck movement analysis of subjects suffering from chronic whiplash-associated disorders (WAD). Three-dimensional (3-D) motion data is collected by a commercially available system. Head rotation, defined in this as the rotation angle around instantaneous helical axis (IHA), used extracting number variables (e.g., angular velocity and range, symmetry motion). Statistically significant differences were found between controls with WAD variables.

For all segments and tests, a modified Kalman filter quasi-static sensor fusion algorithm were equally accurate (precision accuracy ∼2–3°) compared to normalized least mean squares filtering, recursive least-squares filtering standard filtering. The aims to: (1) compare adaptive techniques used for (2) evaluate the precision chosen filter. Motion sensors (based on inertial measurement units) are limited by accumulative integration errors arising from bias. This drift can partly be handled...

Twenty-four competitive powerlifters (n = 14) 10) performed three repetitions exercises using a load equivalent 70% their respective one-repetition maximum. main outcome measures three-dimensional for start position, minimum maximum angle alignment, range motion...

Abstract Innovation has become increasingly important for most industries to cope with rapid technological changes as well changing societal needs. Even though there are many sectors specific needs when it comes supporting innovation, the medical technology sector is facing several unique challenges that both increases lead-time from idea finished product and decreases number of innovations developed. This paper presents a proposed innovation guide been developed evaluated support process...

A hip prosthesis design with larger femoral head size may improve functional outcomes compared to the conventional total arthroplasty (THA) design. Our aim was compare range of motion (RoM) in lower body joints during squats, gait and stair walking using a wearable movement analysis system based on inertial measurement units (IMUs) three age-matched male groups: 6 males THA (THAC), 9 large (LFH) design, 8 hip- knee-asymptomatic controls (CTRL). We hypothesized that LFH would allow greater...

The present study investigated the relationship between individual differences in timing movements at level of milliseconds and performance on selected cognitive fine motor skills. For this purpose, young adult participants (N = 100) performed a repetitive movement task paced by an auditory metronome different rates. Psychometric measures included digit-span symbol search subtasks from Wechsler battery as well Raven SPM. Fine skills were assessed with Purdue Pegboard test. Motor was...

Purpose: This paper aimed to investigate motor proficiency in fine and gross function, with a focus on reaction time (RT) movement skill, patients fibromyalgia (FM) chronic fatigue syndrome (CFS) compared healthy controls (HC). Methods: A total of 60 individuals (20 CFS, 20 FM, HC), age 19–49 years, participated this study. Gross function the lower extremity was assessed using RT task during gait initiation response an auditory trigger. Fine upper measured precision (the Purdue Pegboard...

Ordinal scales with low resolution are used to assess arm function in clinic. These may be improved by adding objective kinematic measures. The aim was analyze within-subject, inter-rater and overall reliability (i.e., including within-subject reliability) check the system’s validity of measures from inertial sensors for two such protocols on one person. Twenty healthy volunteers repeatedly performed tasks, finger-to-nose drinking, during test sessions different raters. Five sensors,...

This paper presents a new method for classification of neck movement patterns related to whiplash-associated disorders (WAD) using resilient backpropagation neural network (BPNN). WAD are common diagnosis after trauma, typically caused by rear-end car accidents. Since physical injuries seldom found with present imaging techniques, the can be difficult make. The active range is often visually inspected in patients pain, but this subjective measure, and more objective decision support system,...

The authors investigated whether the discrepancy noted in literature regarding delayed and decreased activity vastus medialis obliquus (VMO) people with patellofemoral pain (PFP) depends on nature of open kinetic chain (OKC) closed (CKC) experimental task. They hypothesized that VMO would be more CKC tasks than OKC tasks. Women PFP (n = 17) healthy controls performed isometric quadriceps contractions manipulated only application resistance.
