Purpose: Revealing the relationship between mobility impairment and life satisfaction can help to propose effective interventions to secure mobility and life satisfaction. However, the relationship remains unclear and lacks quantitative evidence in China. This study therefore assesses the association of mobility impairment, social engagement, and life satisfaction among the older population in China.
Methods: Based on the sample of China Health and Retirement Longitudinal Survey database in 2013, a structural equation modeling is established. The sample size is 4245 with 55.9% with mobility impairment.
Results: The model shows that the length of suffering from disability is significantly related to mobility impairment (β = 0.058, p < 0.001). Mobility impairment is inversely related to social engagement (β = -0.300, p < 0.001) and life satisfaction (β = -0.311, p < 0.001). Social engagement is positively related to life satisfaction (β = 0.211, p < 0.001). Moreover, the relationships have some differences for the seniors with different sociodemographic characteristics and living in different residential areas.
Conclusions: As seniors get older, they tend to have more severe mobility impairment and participate less in social activities. Those with higher mobility impairment are more likely to report lower life satisfaction partly because they usually participate less in social activities. Different strategies are suggested to be adopted to improve the life satisfaction of the older population from the aspects of promoting mobility and social engagement, including improving the design of transport facilitates, providing assistive facilities for the seniors with severe mobility impairment, promoting the accessibility of community leisure and healthcare services, and constructing more community senior activity centers.

Background: Clinical research has offered many definitions and fragmented perspectives of joint morbidity in haemophilia. As joint damage, pain and mobility impairment can be present without clinical record of persistent bleeding, a person-centric joint morbidity characterisation remained a priority for the haemophilia community, giving rise to the 'problem joint' concept. As diagnosing and managing joint morbidity is critical, the aim of this study was to analyse the holistic burden of problem joints in people with moderate or severe haemophilia A (HA).

In this paper, we undertake a systematic exploration of soliton turbulent phenomena and the emergence of extreme rogue waves within the framework of the one-dimensional fractional nonlinear Schrödinger (FNLS) equation, which appears in many fields, such as nonlinear optics, Bose-Einstein condensates, plasma physics, etc. By initiating simulations with a plane wave modulated by small noise, we scrutinized the universal regimes of non-stationary turbulence through various statistical indices. Our analysis elucidates a marked increase in the probability of rogue wave occurrences as the system evolves within a certain range of Lévy index α, which can be ascribed to the broadened modulation instability bandwidth.

Purpose/objective: The present review examined the evidence for a potentially bidirectional association between mobility function and cognitive function in midlife and older adulthood.
Research Method/design: In 2023-2024, we conducted a scoping review by carrying out systematic searches on Google Scholar, PubMed, and PsycINFO for articles that included measures of mobility function and cognitive function.
Results: Of the 1,504 articles screened, 40 were included for review.
Mechanically stable polymer networks incorporating polymeric ionic liquids for enhanced conductivity in solid-state electrolytes.

Enhancing both ionic conductivity and mechanical robustness remains a major challenge in designing solid-state electrolytes for lithium batteries. This work presents a novel approach in designing mechanically robust and highly conductive solid-state electrolytes, which involves ionic liquid-based cross-linked polymer networks incorporating polymeric ionic liquids (PILs). First, linear PILs with different side groups were synthesized for optimizing the structure.

Clinical practice guidelines (CPGs) are developed to synthesize evidence into recommendations for clinical practice. Minimal evidence exists on the evaluation practice of physical therapists in the treatment of patients with neck pain. : We sought to describe (1) the extent to which clinicians perform the Neck Pain CPG-recommended examination measures and (2) the percentage of patients properly classified.
