Obstructive sleep apnea (OSA) is a breathing disorder characterized by the repeated collapse of the pharyngeal airway during sleep. Previous studies have reported that tongue base deformation may be a major contributing factor. However, overnight monitoring of tongue motion in patients with OSA has previously been impracticable. We developed a wearable ultrasound device for prolonged recording during natural sleep of the changes in tongue base thickness (TBT) in patients with OSA. The maximum TBT was fed into a polysomnography system so that physiologic signals and TBT data were simultaneously monitored. Subject trials revealed that TBT increased significantly during snoring, hypopnea and apnea events during natural sleep in patients with OSA. Moreover, the data revealed that the location of the maximum TBT during normal breathing was significantly different compared with the location during obstructive respiratory events, which implies a posterior or inferior displacement of the tongue base during sleep apnea.  相似文献

【】目的 通过数字化测量双脚运动参数的方法,分析光线视觉提示对帕金森患者冻结步态的影响。 方法 选取10名具有冻结步态症状的帕金森患者,其中男性5名,女性5名,平均年龄62.3岁,Hoehn-Yahr评分为3-4级,以可穿戴设备采集光线视觉提示开和关两种状态下患者直线行走时的加速度数据,并对比分析步长、步频、步速、最大冻结指数(maxFI)和平均冻结指数(avrFI)等步态特征参数。 结果 在光线视觉提示开的状态下帕金森患者的步长、步频、步速、maxFI和avrFI等特征参数较光线视觉提示关的状态明显改善,均有显著性差异(P<0.01)。 结论 可穿戴设备可用于评估冻结步态,光线视觉提示可以显著改善帕金森病患者冻结步态的步态参数。  相似文献

Several assistive technologies are available to help visually impaired individuals avoid obstructions while walking. Unfortunately, white canes and medical walkers are unable to detect obstacles on the road or react to encumbrances located above the waist. In this study, I adopted the cyber-physical system approach in the development of a cap-connected device to compensate for gaps in detection associated with conventional aids for the visually impaired. I developed a verisimilar, experimental route involving the participation of seven individuals with visual impairment, including straight sections, left turns, right turns, curves, and suspended objects. My aim was to facilitate the collection of information required for the practical use of the device. My findings demonstrate the feasibility of the proposed guiding device in alerting walkers to the presence of some kinds of obstacles from the small number of subjects. That is, it shows promise for future work and research with the proposed device. My findings provide a valuable reference for the further improvement of these devices as well as the establishment of experiments involving the visually impaired.  相似文献

Context

Quality of life (QoL) is increasingly recognized as an important outcome of cancer treatment. Previous studies have examined clinical predictors of QoL, but with the increasing prevalence of wearable sensors that monitor sleep and activity patterns, further investigation into whether these behaviors are predictive of post-treatment QoL is now feasible. Among patients receiving aggressive cancer treatment such as hematopoietic cell transplantation (HCT), analysis of circadian rhythms (24-hour patterns of sleep and activity) via wearable sensors is limited.

Objective

To evaluate the relationship between overall QoL and circadian rhythms in patients receiving allogeneic HCT.

Methods

Patients wore an ActiGraph GT3X (Pensacola, FL) activity monitor for at least 72 hours before the initiation of conditioning chemotherapy and transplantation and completed a QoL (Functional Assessment of Cancer Therapy-General [FACT-G]) assessment. QoL assessments were also completed 1, 3, and 6 months after HCT.

Results

Patients (n = 45, M age = 55) were mostly male (66%) with a total FACT-G score of 80.96 (SD = 16.05) before HCT. Mixed models revealed robust cross-sectional associations between overall QoL and multiple circadian rhythmicity parameters, including durations of high physical activity, overall circadian rhythmicity, and earlier starts of daily activity (P's < .01). Recovery of QoL after transplant was predicted by longer pre-transplant durations of high physical activity (P = .04) and earlier evening retirement (P = .04).

Conclusion

Our findings suggest that wearable sensor information is a promising method of predicting recovery of QoL after HCT. Additional studies are needed to confirm these findings in a larger sample.  相似文献

目的:研究可穿戴式智能足底压力视觉反馈技术对脑卒中患者平衡功能的影响,并探讨此技术在临床平衡功能训练中的应用方式和价值。方法:选择病程为8个月内的脑卒中患者30例,随机分配到试验组和对照组,每组15例。对照组接受常规平衡训练,试验组在可穿戴式智能足底压力视觉反馈技术配合下进行平衡训练,每次30min,每周5次,共训练4周。比较训练前及训练4周后两组患者的平衡功能评分,包括Berg平衡量表(BBS),"起立—行走"计时测试(TUG)和采用可穿戴式智能足底压力视觉反馈鞋垫记录的睁眼和闭眼静态平衡率,以评估训练的有效性和对照组与试验组间训练效果的差异。结果:训练前两组患者的一般资料、BBS及TUG评分和静态平衡率均无显著性差异(P0.05);训练后,试验组和对照组患者各观察指标与训练前相比均有显著改善(P0.05)。试验组的训练后与训练前各平衡功能评分差值与对照组相较更大,且有显著性差异(P0.05)。结论:应用可穿戴式智能足底压力视觉反馈技术进行平衡功能训练可以改善偏瘫患者的平衡功能,且较常规方法更有效。  相似文献
