In recent years, considerable research efforts have been devoted to the development of wearable multi-functional sensing technology to fulfill the requirements of healthcare smart detection, and much progress has been achieved. Due to the appealing characteristics of flexibility, stretchability and long-term stability, the sensors have been used in a wide range of applications, such as respiration monitoring, pulse wave detection, gait pattern analysis, etc. Wearable sensors based on single mechanisms are usually capable of sensing only one physiological or motion signal. In order to measure, record and analyze comprehensive physical conditions, it is indispensable to explore the wearable sensors based on hybrid mechanisms and realize the integration of multiple smart functions. Herein, we have summarized various working mechanisms (resistive, capacitive, triboelectric, piezoelectric, thermo-electric, pyroelectric) and hybrid mechanisms that are incorporated into wearable sensors. More importantly, to make wearable sensors work persistently, it is meaningful to combine flexible power units and wearable sensors and form a self-powered system. This article also emphasizes the utility of self-powered wearable sensors from the perspective of mechanisms, and gives applications. Furthermore, we discuss the emerging materials and structures that are applied to achieve high sensitivity. In the end, we present perspectives on the outlooks of wearable multi-functional sensing technology.

Objective: The aim of the study is to evaluate the effect of different traditional Chinese and western medicine rehabilitation techniques on motor dysfunction after stroke using a network meta-analysis. Methods: CNKI, Wanfang, PubMed, Embase, and Cochrane databases were searched from inception to September 2022. We independently searched and screened randomized controlled trials of rehabilitation techniques for poststroke motor dysfunction treatment, evaluated the quality, and analyzed the data using Stata 14.0. Results: Seventy-four randomized controlled trials involving nine rehabilitation techniques and 5128 patients were included. The results of network meta-analysis showed the following orders regarding improvement of the total scores of Fugl-Meyer Assessment, Action Research Arm Test, and Berg Balance Scale: biofeedback therapy > mirror therapy > repetitive transcranial magnetic stimulation > acupuncture therapy > transcranial direct current stimulation > Taichi > common therapy, virtual reality > transcranial direct current stimulation > repetitive transcranial magnetic stimulation > mirror therapy > common therapy, and acupuncture therapy > virtual reality > neuromuscular electrical stimulation > mirror therapy > common therapy > transcranial direct current stimulation, respectively. Conclusions: Biofeedback therapy had the best comprehensive effect, while virtual reality was the best intervention for improving the index of action research arm test and Fugl-Meyer Assessment–lower extremity. Acupuncture therapy improved lower limb balance function.

With the gradual improvement of people’s health awareness, wearable devices occupy an important position in daily health care and human physiological activity monitoring. As traditional silicon-based electronic products face problems such as interface mismatch, silk fibroin has gradually become an alternative choice for next-generation wearable electronic devices due to its excellent performance. Herein, an ultra-thin transparent and flexible multi-functional sensor based on silk hydrogel with self-patterned microstructure is proposed. The silk hydrogel exhibits superior transparency (>82%) and thin thickness (∼100 μ m). Furthermore, the self-patterned microstructure on the silk hydrogel surface is beneficial for the high sensitivity of pressure sensing response (1.6 kPa ⁻¹ ). This device exhibits advantageous performance on temperature (top sensitivity of 6.25% °C ⁻¹ ) and humidity (top sensitivity of 0.16% RH ⁻¹ ) sensing response. It also shows fast response (0.16 s) and durable stability (over 2000 dynamic cycles). Moreover, this device can be applied to monitor human facial expression, joint movements, temperature change, breathing and other health indicators. It is worth mentioning that this multi-functional sensor can monitor the signal of breathing and throat, so it can be applied to the clinical physiological activity monitoring of patients with upper respiratory tract infection. In addition, we also demonstrate a grasping and relaxing experiment of intelligent manipulator to verify the pressure and temperature sensing performance, providing a possibility for its application in the field of prosthetics. According to these advantages, the reported ultra-thin transparent multi-functional sensor based on silk hydrogel has broad prospects in the fields of health monitoring, intelligent prosthetics, and electronic skin, etc.

Introduction: This study aimed to comprehensively evaluate the therapeutic efficacy of cerebellar repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of post-stroke dysphagia (PSD). Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched PubMed, Cochrane Library, Embase, and Web of Science to identify relevant randomized controlled trials (RCTs) investigating the application of cerebellar rTMS in the treatment of PSD. Inclusion and exclusion criteria were rigorously applied during the screening process, and pertinent characteristics of the included RCTs were meticulously extracted. The I2 statistic was employed to assess heterogeneity, and meta-analysis was conducted using Stata 17 software. The Cochrane Risk of Bias 2 tool and PEDro scale were utilized to evaluate bias risk and literature quality. Results: Our analysis encompassed a total of 5 RCTs involving 673 patients with dysphagia who met the inclusion criteria. The findings indicated a significant positive impact of cerebellar rTMS when combined with traditional swallowing exercises on PSD, demonstrating superior efficacy compared to conventional swallowing exercises in isolation. Furthermore, the study revealed no statistically significant differences based on stimulation site (unilateral vs. bilateral cerebellum), stimulation mode (rTMS vs. intermittent theta-burst stimulation), and stimulation frequency (5 Hz vs. 10 Hz). Conclusion: The amalgamation of cerebellar rTMS with conventional swallowing exercises demonstrates notable efficacy, surpassing the outcomes achievable with traditional exercises alone. The sustained effectiveness observed underscores the potential of cerebellar rTMS as an innovative avenue in the field of neurorehabilitation for PSD. This study contributes valuable insights into the prospect of utilizing cerebellar rTMS as an adjunctive therapeutic strategy in the management of PSD, emphasizing its relevance for further exploration and clinical application.

Objective: To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) combined with repetitive peripheral magnetic stimulation (rPMS) on upper limb motor dysfunction after stroke.Methods: We systematically searched databases up to May 2024, including PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang, and CBM. Randomized controlled trials (RCTs) examining the application of rTMS combined rPMS on upper limb motor dysfunction after stroke were included based on predefined inclusion criteria. We used Cochrane Risk of Bias 2 tool to assess bias risk of the included RCTs. Meta-analysis was conducted using RevMan 5.4 and Stata 17.0 software.Results: A total of 9 RCTs involving 483 participants were included in this study. Compared with the control groups that used either conventional therapy or rTMS alone, the experimental group that used rTMS combined rPMS showed significant improvements in stroke patients' upper limb motor function [MD = 3.65, 95% CI (2.75, 4.54), P < 0.05], ability of daily living [MD = 4.50, 95% CI (3.50, 5.50), P < 0.05], and spasticity [MD = –0.34, 95% CI (−0.48, −0.20), P < 0.05]. Meanwhile, in terms of neurophysiological indicators, significant differences were found both for motor evoked potential latency [MD = −1.77, 95% CI (−3.19, −0.35), P < 0.05] and motor evoked potential amplitude [MD = 0.25, 95% CI (0.01, 0.49), P < 0.05].Conclusion: This study provides low-level evidence that the therapy of LF-rTMS or HF-rTMS combined with rPMS can improve the upper limb motor function and daily living ability of stroke patients. However, given that the low quality of the evidence for the evaluation results, further evidence from high-quality studies is needed to substantiate this conclusion.Systematic review registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024539195, PROSPERO Platform [CRD42024539195].

Background: To evaluate the efficacy of multiple acupoint combinations for the treatment of post-stroke cognitive impairment (PSCI) using a network meta-analysis method. Methods: Searches for clinical randomized controlled trials (RCTs) of various types of acupuncture treatments for post-stroke cognitive dysfunction were conducted, data were extracted from studies selected according to the inclusion criteria, and the RCTs included in the analysis were assessed separately for risk of literature bias. Network meta-analysis was performed using Stata 14.0. Results: Sixteen RCTs involving 1257 patients were included, which involved 9 groups of acupoint treatment plans. The best treatment plan for improving the mini-mental state examination score of PSCI was a cephalic plexus spur (99.7%). The best treatment option for improving the montreal cognitive assessment score for PSCI was Zishen Yisui acupuncture therapy (ZSYSA) (77.3%). The best option for improving the barthel index score of PSCI was ZSYSA (99.2%). In terms of improving the overall clinical outcomes of PSCI, the best treatment option for improving the overall clinical effectiveness of PSCI is ZSYSA Therapy (92.2%). Conclusion: The analysis of all results shows that ZSYSA can significantly improve PSCI compared to other acupuncture therapies. Strengths and limitations of this study: This is the 1^st study on the treatment of PSCI with different acupoint combinations based on a network meta-analysis method, which provides a reference for clinical rehabilitation workers; all included studies were randomized controlled trials, which increased the reliability of this study. Limitations; The number of relevant clinical studies retrieved was too small, and all included clinical trials were located in China; therefore, there is a great possibility of publication bias; Most of the included studies did not clearly explain the random distribution mode, follow-up, distribution concealment, or other experimental conditions. Therefore, selection and reporting biases cannot be excluded, suggesting that the quality of the literature is not high; Because of the strict inclusion criteria, the number of studies was limited, and subgroup analysis could not be performed according to the time of onset and the length of the disease course.
