解析

Tetraplegia/,tetrə'pli:dʒiə/        

释义   n. 四肢瘫痪,四肢麻痹(等于 quadriplegia)

例句   Spinal cord injury may cause tetraplegia or paraplegia, which is a great damage to the abilities of people' daily living. 脊髓损伤往往造成不同程度的四肢瘫或截瘫,是一种严重致残性的创伤。


概述

随着社会现代化程度的提高,特别是交通工具的发展,脊髓损伤的发病率逐年升高。 全球统计脊髓损伤发生率是223 ~755 例/百万人,各地区患病率和发病率的数据相差很大,与当地人口和社会经济因素有关,50%患者诊断是科学完整的,其中 1/3 为四肢瘫痪患者。我国发病率也有明显上升,据有关资料表明,我国脊柱损伤发病率25 ~35 例/10万人,其中1/7 ~1/6 伴有脊髓损伤,多以青壮年为主。病因及病理机制颈髓损伤是 SCI中最常见损伤类型,占 SCI损伤 55% ~75%,病死率可高达26%,

Generalizability can also refer to the number of grip types that a user can switch between using the same decoder. A limitation of training minimal-class decoders for individual test items is that additional setup time is needed to switch grips, resulting in standardized testing that stretches across days. This can confound effects specific to objects (eg, weight, shape) with time effects (eg, learning) and limit opportunities for reassessing performance over time. It also fails to address user priorities of spontaneity, decreased setup times, and number of functions available per decoder. For this reason, multiclass GRT decoders were implemented that allowed assessment of all objects without retraining. Performance with the multiclass decoder (see fig 5D) was similar to the single-class decoder for some objects (peg, weight, fork, video tape) but not others (can, block). For block and can, the participant required more time to select the appropriate grip decoder-calibration, reducing transfer rate in multiclass conditions compared to simpler 1 to 2 class decoders. The additional selection time for block was likely related to observed overlap in cortical representation with other GRT object or grips.

通用性还可以指代用户可以使用同一解码器在各种握持类型之间进行切换的数量。为单个测试项目训练最低级别的解码器的局限性在于,需要额外的设置时间来切换手柄,从而导致跨越几天的标准化测试。这可以将特定于对象的效果(例如,重量,形状)与时间效果(例如,学习)混淆,并限制了随时间推移重新评估性能的机会。它还无法解决用户的自发优先级,减少的建立时间以及每个解码器可用功能的数量。因此,实施了多类GRT解码器,可以对所有对象进行评估而无需重新训练。对于某些对象(钉子,重量,叉子,录像带),多类解码器(参见图5D)的性能类似于单类解码器,而其他对象(罐头,块)则没有。对于块和罐,参与者需要更多时间来选择适当的抓地力解码器校准,与更简单的1至2类解码器相比,降低了在多类条件下的传输速率。额外的阻滞选择时间可能与观察到的皮层表现与其他GRT对象或夹具的重叠有关。
