Background

:The best approach to rehabilitate the control of everyday whole-body movement (e.g. rise-to-walk) after pathology remains unclear in part because the associated controlled performance variables are not known. Rise-to-walk can be performed fluidly (sit-to-walk) or non-fluidly (sit-to-stand, proceeded by gait-initiation). Biomechanical variables that remain consistent in health regardless of how rise-to walk is performed represent controlled performance variable candidates which could monitor rehabilitative change.

Research Question

:To determine if any biomechanical parameters remain consistent across rising-to-walk (RTW) subtasks (sit-to-stand, gait-initiation, and sit-to-walk) in healthy adults for purposes of movement control assessment in clinical practice.

Methods

:Data sources included Medline, Cinahl, and Scopus databases, and the grey literature. Study selection was based on eligibility criteria and must have reported spatiotemporal, kinematic and/or kinetic biomechanical parameters featuring >1 RTW subtask. Data extraction and synthesis; standardised-mean-differences (SMDs) were calculated (pooled if replicated in >1 study) for each parameter. Consistency was determined if SMD95 %CIs included the zero-effect line.

Results

:Nine studies (n = 99) were included (40 ± 7.5yrs). Seven parameters were replicated in >1 study and subjected to meta-analysis (fixed-effect model). Two were consistent between sit-to-stand and sit-to-walk: flexion-momentum time (M(95 %CI) = 0.055(-0.423 to 0.533); p = 0.823) and peak whole-body-centre-of-mass vertical velocity (M(95 %CI)= -0.415(-0.898 to 0.069); p = 0.093); and centre-of-pressure to whole-body-centre-of-mass distance at toe-off (M(95 %CI)= -0.137(-0.712 to 0.439); p = 0.642) between gait-initiation and sit-to-walk. Another 20 parameters were consistent based on single-study SMDs.

Significance

:Consistent parameters might exist across RTW subtasks. However, the evidence is based on few studies with small samples and variable RTW protocols. Future studies designed to confirm consistency using a standardised RTW protocol are needed.

识别从上到下的子任务中一致的生物力学参数，以指导实践中的康复：系统的文献综述

背景

：病理后，恢复对日常全身运动（例如，抬头走路）的控制的最佳方法尚不清楚，部分原因是未知的相关控制性能变量。可以以流体方式（坐着走）或非流体方式（坐着站着，通过步态起始进行）进行起身。无论如何进行抬举，健康状况均保持一致的生物力学变量代表可以监控康复变化的受控性能变量。

研究问题

：为了确定临床实践中的运动控制评估目的，确定健康成年人中跨步上升（RTW）子任务（坐姿，步态起始和坐姿）是否有任何生物力学参数保持一致。

方法

：数据来源包括Medline，Cinahl和Scopus数据库以及灰色文献。研究的选择基于资格标准，并且必须报告具有> 1个RTW子任务的时空，运动和/或动力学生物力学参数。数据提取和综合；计算每个参数的标准均差（SMD）（如果在> 1研究中重复，则归并）。如果SMD95％CIs包括零影响线，则确定一致性。

结果

：包括9个研究（n = 99）（40±7.5年）。在1项研究中复制了7个参数，并进行了荟萃分析（固定效应模型）。坐着站立和坐着步行之间的两个条件是一致的：屈曲动量时间（M（95％CI）= 0.055（-0.423至0.533）； p = 0.823）和全身峰值峰值质量垂直速度（M（95％CI）= -0.415（-0.898至0.069）; p = 0.093）; 步态起始与坐姿之间脚趾离开时的压力中心至全身质量中心距离（M（95％CI）= -0.137（-0.712至0.439）; p = 0.642） -步行。基于单项研究SMD，其他20个参数保持一致。

意义

：RTW子任务中可能存在一致的参数。但是，证据是基于少量样本和可变RTW方案的研究。需要使用标准化的RTW协议来确认一致性的未来研究。
