Unsuitable foot clearance and step length lead falling accidents; thus, these gait parameters should be monitored for fall prevention. According to previous study, users prefer wrist as a position to wear wearable device for daily gait monitoring. Therefore, we have been developing gait monitoring method using wearable device on a wrist. Our previous method classifies gaits with different foot clearance or step length by machine learning technique using 3-axis acceleration data obtained from wearable device on a wrist. The results of our previous study showed that this method could classify gaits for each step. However, accuracy of our previous method was insufficient because individual difference of arm acceleration due to stature or gait speed were not considered. The objective of this study is to propose the gait classification method based on individual difference. The proposed method classifies three gaits with different foot clearance and step length by machine learning technique using combination of arm acceleration, stature, and gait speed. The proposed method was tested for 1800 steps performed from ten participants. The proposed method could classify three gaits with accuracy greater than 0.9. These results indicate possibility that the proposed method can be used for gait monitoring using wearable device.

It is yet not known whether the variation in knee orthotics pressure would lead to changes in muscle activity during-sit-to-stand postural transition in patients with knee osteoarthritis (OA). Participants in this analytical study were patients with knee OA. The research design was a cross-sectional study. They were enrolled in the study through a sample of convenience method. The primary outcome measure was surface electromyography for measuring muscle activity while changing knee orthotics pressure during sit-to-stand motion. Data were summarized with mean and standard devia-tion while Friedman’s test was performed for multiple comparison of variables, at a significance level of p = 0.05. Seven elderly patients with knee osteoarthritis (mean age 71.4 ± 11.8 years) participated in the study. Moderate orthotics (7.3 mmHg) led to a significant increase in the percentage maximum voluntary contraction (MVC) of tibialis anterior compared to that obtained without orthotics. Rectus femoris, vastus medialis, vastus lateralis, and biceps femoris tended to increase the % MVC with an increase in wearing pressure. It was therefore concluded that the muscle activity during sit-to-stand motion could be increased in patients with knee osteoarthritis by wearing flexible orthotics with varying pressure.

Modeling of the Vasorelaxation Mechanism by Acupuncture/Moxibustion Stimulation for Preventing Arteriosclerosis -Review Paper- 査読有り国際誌

Arteriosclerosis requires early detection and treatment. However, its treatment remains insufficiently established. Elucidating the mechanisms of vasorelaxation may lead to early treatment and contribute to the prevention of diseases caused by arteriosclerosis. The ability of acupuncture/moxibustion stimulation to temporarily increase vasorelaxation and vascular flow has been extensively reported, but its mechanism remains unknown. We successfully modeled the mechanism starting from acupuncture/moxibustion stimulation to vasorelaxation/vasodilation by collating the results of numerous studies in various fields, such as medicine, biology, neurosciences, and pharmacology. Ion channels, including transient receptor potential (TRP) channels, exist at free nerve endings. Acupuncture/moxibustion stimulation is sensed by its ion channels and generates nitric oxide in three subsequent pathways, which leads to vasorelaxation. The three pathways are 1) the nNOS activity pathway (based on neural information), 2) eNOS activity pathway (based on vascular wall shear stress), and 3) iNOS activity pathway (based on multiple cytokines produced by macrophages). These pathways differ depending on the external stimulus; however, in each case, they lead to vasorelaxation and contribute to arteriosclerosis prevention. These pathways can be expected to create complex circuits and produce sustained stimulation effects. This model is expected to contribute to the expansion of the research fields and improvement of treatment methods for medical professionals.
