The Challenges and Pitfalls of Detecting Sleep Hypopnea Using a Wearable Optical Sensor: Comparative Study.

J Med Internet Res 2021 Jul 29;23(7):e24171. Epub 2021 Jul 29.

Center for Sleep Medicine, Sleep Research and Epileptology, Barmelweid, Switzerland.

Background: Obstructive sleep apnea (OSA) is the most prevalent respiratory sleep disorder occurring in 9% to 38% of the general population. About 90% of patients with suspected OSA remain undiagnosed due to the lack of sleep laboratories or specialists and the high cost of gold-standard in-lab polysomnography diagnosis, leading to a decreased quality of life and increased health care burden in cardio- and cerebrovascular diseases. Wearable sleep trackers like smartwatches and armbands are booming, creating a hope for cost-efficient at-home OSA diagnosis and assessment of treatment (eg, continuous positive airway pressure [CPAP] therapy) effectiveness.

Task Oriented Training Activities Post Stroke Will Produce Measurable Alterations in Brain Plasticity Concurrent with Skill Improvement.

Top Stroke Rehabil 2021 Jul 28:1-14. Epub 2021 Jul 28.

Department of Exercise and Nutrition Science, George Washington University, Washington, DC, USA.

Background: Task-oriented training with upper extremity (UE) skilled movements has been established as a method to regain function post stroke. Although improved UE function has been shown after this type of therapy, there is minimal evidence that brain plasticity is associated with this training. The accelerated skill acquisition program (ASAP) is an example of an approach for promoting UE function using targeting movements. Read More

Examining the influence of mental stress on balance perturbation responses in older adults.

Exp Gerontol 2021 Jul 24;153:111495. Epub 2021 Jul 24.

University of Maryland School of Medicine, Department of Physical Therapy and Rehabilitation Science, Baltimore, MD 21201, USA. Electronic address:

Background: Reach-to-grasp responses following balance perturbations are important to fall prevention but are often ineffective in older adults. The ability to shift attention from an ongoing cognitive task to balance related processes has been shown to influence reach-to-grasp effectiveness in older adults. However, the added influence of stress and anxiety - known to negatively affect attention shifting ability - has not yet been explored in relation to recovery from balance perturbations. Read More

Wrist-worn Hand Gesture Recognition while Walking via Transfer Learning.

IEEE J Biomed Health Inform 2021 Jul 27;PP. Epub 2021 Jul 27.

Walking, one of the most common daily activities, causes unwanted movement artifacts which can significantly deteriorate hand gesture recognition accuracy. However, traditional hand gesture recognition algorithms are typically developed and validated with wrist-worn devices only during static human poses, neglecting the critical importance of dynamic effects on gesture accuracy. Thus, we developed and validated a signal decomposition approach via empirical mode decomposition to accurately segment target gestures from coupled raw signals during dynamic walking and a transfer learning method based on distribution adaptation to enable gesture recognition through domain transfer between dynamic walking and static standing scenarios.

Advances in forensic diagnosis of electric shock death in the absence of typical electrical marks.

Int J Legal Med 2021 Jul 27. Epub 2021 Jul 27.

Forensic and Pathology Laboratory, Judicial Expertise Center, Jiaxing University Medical College, Jiaxing, 314001, ZJ, China.

Electrical injury is a relatively uncommon but potentially devastating form of multi-system injury with high morbidity and mortality. In common electric injury cases, it is usually difficult to find characteristic changes of electric injury in major organs by using routine histopathological test methods unless there are landmark traces of electric injury, known as electric marks. How to determine electric shock death, especially in the absence of typical electrical marks on the body surface in some cases (which account for about two-thirds of electric injury cases), remains a challenging problem in forensic practice.

Reproducibility of bone age assessment from DXA hand scans: expert versus novice.

Ann Hum Biol 2021 Jul 26:1-3. Epub 2021 Jul 26.

School of Sport, Exercise and Health Sciences, Loughborough University, Loughborough, UK.

Dual-energy x-ray absorptiometry (DXA) scans are frequently used in human biological research to study bone health and body composition. Hand-wrist scans for the assessment of skeletal maturity can also be easily obtained in immature research participants who are being scanned to assess bone health. Whilst assessment by an expert is the desired arrangement such expertise may not be available, and thus knowledge of the relative reproducibility of a trained novice and an acknowledged expert is pertinent.
