Abstract

Introduction: The aim of this review was to systematically evaluate the available evidence on the effectiveness of internet-based telerehabilitation among patients after total joint arthroplasty regarding pain, range of motion, physical function, health-related quality of life, satisfaction, and psychological well-being. Methods: This was a systematic review with meta-analysis based on the Cochrane Handbook for Systematic Reviews of Interventions guidelines. Studies published in English or Chinese were searched using defined search periods, databases, and search terms. Two reviewers assessed independently the quality of studies. RevMan 5.3 was used for meta-analysis. Heterogeneity was assessed using the χ 2 and I 2 statistic. A random effect model and mean difference (MD) with 95% confidence interval (CI) was adopted. Standardised mean difference (SMD) was used if the outcome was measured by different scales. Results: Eleven studies with 1020 participants were analysed. Compared to face-to-face rehabilitation, internet-based telerehabilitation showed no significant difference in outcomes of pain (SMD–0.11, 95% CI–0.32 to 0.10), range of motion in flexion (MD 0.65, 95% CI–1.18 to 2.48) and extension (MD–0.38, 95% CI–1.16 to 0.40), patient-reported physical function (SMD 0.01, 95% CI–0.15 to 0.17), health-related quality of life (SMD–0.09, 95% CI–0.26 to 0.07), satisfaction (SMD–0.04, 95% CI–0.21 to 0.14), and psychological well-being (SMD 0.10, 95% CI–0.13 to 0.33). Internet-based telerehabilitation showed better outcomes in physical functional tests (SMD–0.54, 95% CI–1.08 to–0.01). Discussion: This review suggests that internet-based telerehabilitation has comparable effectiveness to face-to-face rehabilitation on rehabilitation outcomes among patients after total joint arthroplasty.

Abstract

In this paper, we are concerned with distributed finite-time optimisation of multi-agent systems with unknown high-frequency gain signs under switching digraphs. First, a distributed finite-time gradient estimator-based optimal signal generator is constructed by adopting finite-time stability theory and graph theory. Then, considering the existence of unknown high-frequency gain signs in multi-agent systems, we propose new distributed asymptotic optimisation algorithms via the Nussbaum-type function. Additionally, in order to accelerate convergence, the novel distributed finite-time optimisation algorithms are presented. Both of the newly proposed algorithms can realise optimal consensus of multi-agent systems with unknown high-frequency gain signs under switching digraphs. Finally, two simulation examples are illustrated to verify the proposed algorithms. [ABSTRACT FROM AUTHOR]

Abstract

Abstract A method for the synthesis of high quality indium-doped zinc oxide (In-doped ZnO) nanocrystals was developed using a one-step ester elimination reaction based on alcoholysis of metal carboxylate salts. The resulting nearly monodisperse nanocrystals are well-crystallized with typically crystal structure identical to that of wurtzite type of ZnO. Structural, optical, and elemental analyses on the products indicate the incorporation of indium into the host ZnO lattices. The individual nanocrystals with cubic structures were observed in the 5% In–ZnO reaction, due to the relatively high reactivity of indium precursors. Our study would provide further insights for the growth of doped oxide nanocrystals, and deepen the understanding of doping process in colloidal nanocrystal syntheses.
