Summary: This paper proposes an instance-oriented classification performance metric called degree of credibility (Cr), focusing on the credibility of each instance's prediction, which opens up a new way for classifier evaluation. Additionally, the concept of acceptable classifiers is introduced to judge the model's performance objectively. Experimental results show that Cr has good statistical consistency and physical significance.

Summary: This study characterized the performance of unsupervised 30-second chair stand test (30CST) using accelerometer-derived metrics and assessed its ability to classify fall status in people with multiple sclerosis (PwMS) compared to supervised 30CST. The results showed that non-fallers had different unsupervised 30CST performance compared to supervised 30CST, and the maximum number of 30CST repetitions in unsupervised conditions had a good ability to classify fall status.

Summary: This study examined the effects of fall history on acceleration profiles before, during, and after a near collision with a moving hazard in older adults. It found that older adults without a fall history are more adaptable and able to respond last-minute to unexpected hazards, while older adults with a fall history exhibit more homogenous responses.

Summary: This study explores the relationship between activity during falls and fall-related serious injury in an acute care hospital. The findings suggest that moderate or major injuries caused by falls in this setting are associated with the activity at the time of the fall.

Summary: This study aimed to investigate the effectiveness of ultrasonographic measurements in assessing frailty in the emergency department. The results showed that ultrasound measurements of muscle thickness and asymmetry were moderately associated with frailty, falls, subsequent hospitalizations, and ED revisits.

Summary: Previous studies on obstacle crossing have used expensive optical motion capture systems, which are limited by cost and laboratory requirements. This study developed a practical and inexpensive solution using the Microsoft Azure Kinect to measure obstacle-crossing behavior and validated its performance.

Summary: This study aimed to characterize trajectories in physical performance over time and determine if these trajectories could improve fall prediction. The results showed that the trajectory of physical performance did not meaningfully improve fall prediction from a baseline physical performance assessment.

Summary: A fall-classification framework for patients undergoing total knee replacement (TKR) was proposed and the incidence and circumstances of falls were described. The study found that the incidence of falls decreased after surgery and most falls were caused by disruptions in the base of support and precipitated by extrinsic factors.

Summary: The study found that sensorimotor performance and fall risk worsened with increasing age in community-dwelling adults. Females exhibited slower reaction time, lower muscle strength, and higher fall risk compared to males. Older adults (>= 65 years) in the representative sample performed worse in postural sway and reaction time but better in proprioception and vision compared to Caucasian norms. A significant proportion of younger adults (21-59 years) appeared to have higher fall risk.

Summary: Protective arm reactions are an important mechanism to avoid injuries during unavoidable falls. Previous research has shown that these reactions are influenced by fall height, but it is unclear whether they are also modulated by impact velocity. This study aimed to determine if protective arm reactions are affected by the unpredictable impact velocity of a forward fall.

Summary: This study compared the validity and reliability of velocity field diagram (VFD) and Timed-up-and-go test (TUG) in identifying fall risks among older adults, showing that VFD demonstrated better discriminatory power compared to TUG.

Summary: The COVID-19 pandemic has led to worsened physical function and increased risk of falls, particularly impacting older individuals with reduced physical activity and social isolation. Public health interventions to address decreased physical activity and social isolation among older adults are crucial.

Summary: The study found that the short physical performance battery (SPPB) is not an effective predictor for falls and fall-induced injuries among community-dwelling older Chinese adults. The predictive performance of SPPB alone or in combination with demographic variables and self-reported health conditions was poor.

Summary: Women with low PA-low PF and high PA-low PF are more likely to fall, while worsening PF over time increases fall risk, although increasing PA does not. This highlights the importance of physical activity engagement in reducing fall risk.

Summary: Huntington's disease is associated with motor, cognitive, and behavioral dysfunction. The age of onset is linked to the presentation and severity of behavioral symptoms. As age of onset increases, the odds of reporting behavioral symptoms as the presenting symptom decrease.

Summary: The study found that treadmill training is feasible and safe in individuals with LBD and HD, but longer and more frequent sessions may be needed to see improvements in gait and motor function. Motor and cognitive impairments associated with these diseases may make them less responsive to the effects of treadmill training.

Summary: This study evaluated the perceived benefits and limitations of using community paramedicine for fall prevention strategies from the perspective of older adults, caregivers, and healthcare providers. The results showed that community paramedicine was supported as a model of fall prevention, with strengths such as visibility to the home environment and the ability to implement home modifications. Opportunities identified include providing continuity of care, improving quality and safety, and reducing unnecessary emergency department use. Weaknesses and threats such as funding issues, patient stigma concerns, and struggles with medical data integration were also acknowledged.
