Gait events (i.e., heel strikes and toe-offs) are essential for extracting spatiotemporal parameters segmenting biological signals. While force platforms optical motion capture (OMC) ideal identifying such events, inertial measurement units (IMUs) cheaper more applicable, especially applications outside traditional lab settings. This study aimed to compare IMU- OMC-based gait event detection plates. Seventeen adults walked on a walkway, stepping two plates while an IMU the sacrum...

Abstract Neck pain is a common musculoskeletal problem often accompanied by reduced exercise-induced hypoalgesia (EIH) or hyperalgesia compared with an asymptomatic population. This study investigated EIH in healthy population during experimental neck pain. Forty participants were randomized into this double-blinded parallel-group study. On 4 separate test days (day 0, day 2, 4, and 15), completed the Disability Index scored intensity head movements on numerical rating scale. At end of 0...

Purpose: Altered head range of motion (RoM) and repositioning accuracy (HRA) are commonly reported in neck pain. However, the quality (QoM) is currently not easy to assess clinically. This study investigated agreement rotation recordings using a 3D camera system compared commercially available inertial measurement unit (MOTI).Materials methods: Thirty participants, mean age 26.5 years old (SD 4.4), partook this study. Participants wore Headband with MOTI markers for capture analysis during...

Objective To study the prevalence of foot pain in patients with rheumatoid arthritis (RA) and whether including a 12‐joint count addition to 28‐joint (from Disease Activity Score 28 [DAS28]) improved detection or ankle pain. In addition, association between self‐reported score (SEFAS), patient‐reported function, disease‐specific factors was studied. Methods Physician‐reported data (swollen/tender count, DAS28, medication) (foot/ankle pain, physical global health, SEFAS) were assessed during...

Introduction: Preventative foot self-care is vital for avoiding diabetic ulcer episodes and lowering the risk of amputations. Yet, it demands high levels health literacy cognitive function. Objective: To investigate function in persons presenting with a ulcer. Methods: Participants type 2 diabetes were recruited from tertiary clinic at Steno Diabetes Center North Denmark. The European Health Literacy Survey Questionnaire Addenbrooke’s Cognitive Examination applied. A semi-structured...

Abstract Purpose This study aims to evaluate the accuracy of predicting one-repetition-maximum (1RM) using load-velocity relationship and different repetition-to-failure estimation equations for ten lower-extremity exercises. Methods A total 22 healthy participants were recruited. The tested exercises included ankle, knee, hip joint flexion extension, as well abduction, adduction, leg press. Velocity during concentric phase was measured a linear transducer, individual regression models...

High-intensity interval training (HIIT) has been suggested as an effective treatment approach of childhood obesity. The objective the present study was to examine intensity, enjoyment, and perceived exertion a 4x4-minute play-based HIIT program for children adolescents with 83 participants (42.2% girls, 12.3±1.5 years, 57.8% boys, 12.0±1.6 years) completed 12-week intervention comprising three weekly sessions. After nine sessions (weeks 2, 6, 11), rated (RPE) Borg scale enjoyment activities...

Reducing compressive knee contact forces (KCF) during walking could slow the progression and reduce symptoms of osteoarthritis. A previous study has shown that compensating for hip flexion/extension moment KCF peak occurring early stance (KCFp1). Therefore, this aimed to identify if monoarticular muscle allow compensation while considering different strategies. Gait trials from 24 healthy participants were used make musculoskeletal models, five load-cases examined: (I) Normal, (II) with an...

Patients with spinal pain often exhibit movement limitations and altered motor control, which can be challenging to measure accurately in clinical practice. Inertial measurement sensors present a promising new opportunity develop valid, low-cost, easy-to-use methods for assessing monitoring motion setting. This study aimed investigate the agreement of an inertial sensor 3D camera system range (ROM) quality (QOM) head trunk single-plane movements. Thirty-three healthy, pain-free volunteers...

Foot pain is frequent among people with rheumatoid arthritis (RA). orthoses (FO) are commonly prescribed the intention to reduce symptoms and improve function.How do a custom-made FO affect pain, gait biomechanics daily activity RA?Twenty-five participants RA foot completed this quasi-experimental study using control insole for four weeks then in following weeks. The were customized by plantar shape targeting optimal restoration of normal arch height. A visual analog scale was used monitor...

The purpose was to investigate differences in reliability of running economy measurements between familiar and unfamiliar shoes. Thirty-seven runners were included who all ran shoes while measured at steady state using a treadmill. Each participant tested on two different visits (three sessions total), with trials each the three shoe conditions completed visit. Coefficient variation, standard deviation differences, limits agreement used quantify repeatability (within-visit variation)...

Dysfunction of the tibialis posterior muscle is most common cause adult acquired flat foot. Tibialis weakness has been observed in several patient populations, including those early stages rheumatoid arthritis. However, influence on gait mechanics not fully understood, although instability reported. In 24 healthy participants, 3-dimension lower limb kinematics and kinetics during walking were evaluated bilaterally, before after, a fatigue protocol aiming to decrease right foot adductor...

Acetabular retroversion is a form of hip dysplasia that may cause femoroacetabular impingement syndrome (FAIS), leading to pain and restricted range motion. An exercise intervention aiming at altering pelvis tilt related functional biomechanics be useful first-line for patients who are not eligible surgical repositioning.Does squat gait change following an 8-week targeted program in individuals with symptomatic acetabular FAIS?This prospective study used participants as their own controls....

This study aimed to identify proteins associated with clinical manifestations of knee osteoarthritis (KOA), including performance-based joint function and patient-reported outcome measures (PROM).

Background In magnetic resonance imaging (MRI) segmentation research, the choice of sequence influences accuracy. This study introduces a method to compare sequences. By aligning sequences with specific objectives, we provide an example comparative analysis various for knee images. Methods Based on profile information virtual rays, devised metrics compute edge sharpness and contrast. Edge was performed in five edges (E BB : between cancellous cortical bone, E BC bone cartilage, CF cartilage...

Multidisciplinary lifestyle interventions for children with obesity in Denmark often include recommendations regarding physical activity, but no structured exercise program. We hypothesized that adding high-intensity interval training (HIIT) to a multidisciplinary intervention would improve BMI z-score (primary outcome), waist circumference, blood pressure, and health-related quality of life (HRQOL). This randomized controlled trial included 173 adolescents obesity. Participants were...

Body weight support (BWS) technologies offer effective gait training for individuals with neurological impairments. However, varying dynamic BWS levels may impact specific kinematics, potentially introducing maladaptive movement patterns.
