Background: Motor imagery (MI) was recently shown to be a promising tool in neurorehabilitation. The ability to perform MI, however, may be impaired in some patients with neurological dysfunction. Objective: The objective was to assess the relation between cognitive and motor dysfunction and MI ability in patients with multiple sclerosis (MS). Methods: Thirty patients with MS underwent cognitive and motor screening, and also performed a composite test battery to assess their MI ability. This test battery consisted of a questionnaire, a hand rotation task and a test based on mental chronometry. Patients' MI ability was compared with the MI ability of age-matched healthy controls. Moreover, their MI scores were compared between body sides and were correlated with their scores on tests of motor and cognitive functioning. Results: The average accuracy and temporal organization of MI significantly differed between MS patients and controls. Patients' MI accuracy significantly correlated with impairments in cognitive functioning, but was independent of motor functioning. MI duration, on the other hand, was independent of cognitive performance, but differed between the patients' most and least affected side. Conclusion: These findings are of use when considering the application of MI practice in MS patients' rehabilitation.

Recent Advances in Atherosclerotic Disease Screening Using Pervasive Healthcare

Jingjing Luo, Zhengrong Yan, Shijie Guo, Wei Chen

Summary: Atherosclerosis screening plays an important role in the transformation of the medical model from therapeutic medicine to preventive medicine. This study introduces five cutting-edge pervasive technologies for atherosclerosis screening, including iPPG, laser Doppler, RF, TI, optical fiber sensing, and piezoelectric sensor. These noninvasive and mobile technologies can detect physiological parameters related to atherosclerosis.

Embodied learning in multiple sclerosis using melodic, sound, and visual feedback: a potential rehabilitation approach

Lousin Moumdjian, Joren Six, Renee Veldkamp, Jenke Geys, Channa Van der Linden, Mieke Goetschalckx, Johan Van Nieuwenhoven, Ilse Bosmans, Marc Leman, Peter Feys

Summary: This study investigated the effects of embodied learning on motor and cognitive functions in persons with multiple sclerosis (PwMS). The results showed that balance impairment and information processing speed predicted the speed of executing cognitive sequences. Furthermore, participants who learned performed the sequence faster in the melody condition and overall improved their speed over time.

FIORA : A Flexible Tendon-Driven Continuum Manipulator for Laparoscopic Surgery

Fuhao Wang, Hongbo Wang, Jingjing Luo, Xiaoyang Kang, Haoyang Yu, Hao Lu, Yu Dong, Xiaoxu Jia

Summary: This letter presents a flexible tendon-driven continuum surgical manipulator called FLORA, which aims to solve the problems of low flexibility, poor internal extension, and chopstick effect in most laparoscopic surgical robots. The manipulator is composed of three independent flexible segments in series, driven by twelve tendons, and has good flexibility and rigidity. It also features a compact actuation unit and a kinematic modeling method based on piecewise constant curvature model, which can accurately model and fast decouple the manipulator.

Palpation localization of radial artery based on 3-dimensional convolutional neural networks

Qiliang Chen, Yulin Huang, Xing Zhu, Hong Lu, Zhongzhi Ji, Jiacheng Yang, Jingjing Luo

Summary: In this paper, a regression model using 3D convolution neural networks (CNN) for locating radial artery upon radius at the wrist using near-infrared picture sequences is proposed. Compared to previous 2D models, the 3D CNN model achieved superior performance accuracy and highlighted dynamic changes within image sequences.

Summary: This review analyzes the feasibility and effectiveness of telehealth solutions proposed during the COVID-19 pandemic to ensure the continuity of rehabilitation. The findings suggest that telerehabilitation is a feasible and effective solution for providing continuous rehabilitation while reducing the risk of infection and burden of travel. However, further research is needed to strengthen and confirm these findings.

Hybrid D1DCnet Using Forehead iPPG for Continuous and Noncontact Blood Pressure Measurement

Yunjie Li, Min Wei, Qiliang Chen, Xing Zhu, Hui Li, Hongbo Wang, Jingjing Luo

Summary: Camera-based image sequences can be used to measure blood pressure continuously and noncontactly using a deep-learning approach called Hybrid D1DCnet. The model can predict systolic and diastolic blood pressure by analyzing forehead imaging photoplethysmography (iPPG) waveforms and personal information. The research demonstrates the feasibility and advantages of using this model to monitor circulatory health and contribute to the prevention and intervention of cardiovascular diseases.

Summary: This study analyzed the optimal dosage and effectiveness of aerobic training (AT) and resistance training (RT) on balance, walking capacity, and quality of life (QoL) in stroke survivors. The results showed that AT was the most effective in improving walking capacity, while combining AT and RT was beneficial for improving QoL. High-dose aerobic exercise conducted in rehabilitation facilities was more effective in improving walking capacity in chronic stroke patients.
