Abstract Sentinel lymph node (SLN) biopsy is the standard surgical approach to detect metastasis in breast cancer. Machine learning a novel tool that provides better accuracy for predicting positive SLN involvement cancer patients. This study obtained data from 2890 cases of patients two referral hospitals Iran 2000 2021. Patients whose status was identified were included our study. The dataset consisted preoperative features, including patient gestational factors, laboratory data, and...

The countermovement vertical jump height, flight time, and duration are used to assess athletic performance. Force-plate motion-capture cameras estimate these parameters, yet, their application is limited dedicated lab environments. Despite the potential of inertial measurement units (IMU) for estimating accuracy has not been validated. This study investigates our proposed method height using a sacrum-mounted IMU, during jumping. Eleven individuals performed four jumps each. To obtain we...

Upper extremity pain and injury are among the most common musculoskeletal complications manual wheelchair users face. Assessing temporal parameters of propulsion, such as propulsion duration, cadence, push recovery is essential for providing a deep insight into mobility, level activity, energy expenditure, cumulative exposure to repetitive tasks thus personalized feedback. The purpose this paper investigate use inertial measurement units (IMUs) estimate these by identifying start end time...

One of the main factors in controlling infectious diseases such as COVID-19 is to prevent touching preoral and prenasal regions. Face a habitual behaviour that occurs frequently. Studies showed people touch their faces 23 times per hour on average. A contaminated hand could transmit infection body by facial touch. Since this spontaneous habit not easy, study aimed develop validate technology detect monitor face using dynamic time warping (DTW) KNN (k-nearest neighbours) based wrist-mounted...

Abstract Ice hockey is a dynamic and competitive sport that requires high level of neuromuscular cardiovascular function. An objective assessment skating helps coaches monitor athletes' performance during training sessions matches. This study aimed to estimate the temporal spatial parameters by proposing an optimized configuration wearable inertial measurement units (IMUs) validating system compared in-lab reference systems. Ten participants were recruited skate on 14 m synthetic ice surface...

Hockey skating objective assessment can help coaches detect players’ performance drop early and avoid fatigue-induced injuries. This study aimed to calculate experimentally validate the 3D angles of lower limb joints hockey skaters obtained by inertial measurement units explore effectiveness on-ice distinctive features measured using these wearable sensors in differentiating low- high-calibre skaters. Twelve able-bodied individuals, six low-calibre skaters, were recruited skate forward on a...

Background Up to 70% of individuals with spinal cord injury (SCI) experience shoulder injuries during their lifetime. Previous studies revealed a link between the risk and propulsion-related kinetic kinematic parameters that were measured using SMARTWheel or in-lab motion-capture systems. Despite high accuracy, these systems are time labour intensive not commonly accessible. Objective To develop validate portable accessible method estimate duration push phase hand-mounted inertial...

Vertical jump performance assessment has been used as a tool to study and monitor physical in both athletic non-athletic populations.One of the key parameters describing vertical is height.Although various methods are available for measuring height, force platforms (FP) most precise, accurate, reliable instrument, usually taken gold standard method.As expensive may not be practical outside lab environment, using wearable technologies like tri-axial inertial sensors (IS) an inexpensive...

Consistency in the sitting direction contributes to decreasing intra-subject variability monitoring interface pressure using mat during sitting.To maintain consistency, it is required perform test a way that body's sagittal plane has stable alignment with coordinate system (CS).Current methods employed repeatable on sessions mostly rely visual checkups or motion capture systems requiring tedious marker placement and data processing.

Individuals living with spinal cord injury who use manual wheelchairs are dependent on their upper limb for mobility.The propulsion of a wheelchair is physically demanding muscles.Repetitive loads applied to the shoulder expose users and pain.In fact, 30% 70% experience pain as results repetitive strain injury.Considering dependence users' lives daily routine mobility, considerable burden directly affects quality life independence.Previous studies identified association between...
