Comprehensive concussion assessments first completed for all patients, followed by testing with phybrata...

Concussion injuries remain a significant public health challenge. A unmet clinical need remains for tools that allow related physiological impairments and longer-term risks to be identified earlier, better quantified, more easily monitored over time. We address this challenge by combining head-mounted wearable inertial motion unit (IMU)-based vibration acceleration ("phybrata") sensor several candidate machine learning (ML) models.

Participants across activities were monitored for head impacts using sensors. Intervention suffering a concussion underwent neurocognitive testing entered supervised...

Abstract Background Balance parameters derived from wearable sensor measurements during postural sway have been shown to be sensitive experimental variables such as test duration, number, and location that influence the magnitude frequency-related properties of measured center-of-mass (COM) center-of-pressure (COP) excursions. In this study, we investigated effects number sensors, on reliability standing balance using body-mounted accelerometers. Methods Twelve volunteers without any prior...

A candidate neuromechanical biomarker is demonstrated for monitoring cumulative head impact trauma. This demonstrates a pronounced threshold behavior, corresponding to the onset of physiological changes observed using high resolution brain imaging, and may enable universally deployable wearable dosimeter.

This paper discusses the design and performance of a wearable head impact dosimeter that can be utilized to detect onset, spatial variation, temporal evolution physiological changes in brain caused by sub-concussive impacts, enabling important new injury prevention initiatives.

In this paper, we propose a mesh-based method for motion estimation and compensation over low frequency subband wavelet video coding. We concentrate on edge-detection information apply different parameters using edge magnitude angle values to indicate curvature objects. This helps detect patches between adjacent frames meshes. analyze compare coding efficiency with variety of test sequences.

This research vision and challenges paper focuses on microprocessor design activity-recognition data processing for medical devices in student-athlete health care. Sports are the second leading cause of mild traumatic brain injury (mTBI) people aged between 15 24 years. Significant work has been done use sensors to determine linear rotational acceleration head impacts, their potential correlation concussions. However, recent studies have shown that subconcussive trauma may be a better...

Today's video codecs have evolved primarily to meet the requirements of motion picture and broadcast industries, where high‐complexity studio encoding can be utilized create highly‐compressed master copies that are then one‐way for playback using less‐expensive, lower‐complexity consumer devices decoding playback. Related standards activities largely ignored computational complexity bandwidth constraints wireless or Internet based real‐time communications such as cell phones webcams....
