Lumbar motor control is an important factor for the prevention and improvement of low back pain and the enhancement of sports performance. Interventions for lumbar motor control are complex and difficult; however, training with whole-body vibrations has the potential to be simple and effective. Therefore, this study aimed to verify the effects of 4 weeks of trunk training with whole-body vibrations on each component of lumbar motor control. This single-blind, randomized controlled trial recruited 24 healthy university students (12 males and 12 females) who were randomized to undergo either whole-body or non–whole-body vibration training. The lumbar motion angle and angular jerk cost were measured during each lumbar motor control task (pelvic tilting, ball-catching, and quadruped rocking). There was a significant group × period interaction for the lumbar spine motion angle in the anterior pelvic tilt; however, no significant group × period interaction was observed in the other tasks. Regarding the comparison of pre- and post-intervention outcomes in the whole-body vibration training group, the lumbar spine motion angle of the anterior pelvic tilt was significantly smaller post-intervention than pre-intervention. In the ball-catching task, the lumbar spine motion angle was significantly smaller post-intervention than pre-intervention. Backward rocking resulted in a significantly greater lumbar spine motion angle post-intervention than pre-intervention.
In conclusion, whole-body vibration enhances the control of decreasing lumbar motion. However, it does not improve all components of lumbar motor control and should be considered based on the target component.
腰椎运动控制是预防和改善腰痛、提高运动成绩的重要因素。腰椎运动控制的干预是复杂和困难的;然而,全身振动训练有可能简单而有效。因此,本研究旨在验证4周躯干全身振动训练对腰椎运动控制各组成部分的影响。这项单盲、随机对照试验招募了24名健康的大学生(12名男性和12名女性),他们随机接受全身或非全身振动训练。在每个腰椎运动控制任务(骨盆倾斜、抓球和四足摇晃)中测量腰椎运动角度和角抽搐代价。骨盆前倾时腰椎运动角有显著的组-期交互作用;然而,在其他任务中没有观察到显著的组×期交互作用。全身振动训练组干预前后的结果比较,干预后骨盆前倾腰椎运动角明显小于干预前。在接球任务中,干预后腰椎运动角明显小于干预前。后摇导致干预后腰椎运动角度明显大于干预前。综上所述,全身振动增强了对腰椎运动减少的控制。然而,它并不能改善腰椎运动控制的所有组成部分,应根据目标组成部分进行考虑。

The main aim was to assess the effects of motor imagery (MI) and action observation (AO) plus physical exercise (PE) on pelvic floor and related structures. Forty-four healthy women were randomized into three groups: MI, AO, or sham observation (SO) group. The outcome measures included the pelvic floor muscles (PFM) condition (including basal tone and strength), lumbo-pelvic motor control, and pain sensitivity. All women performed six sessions at the rate of 3 s/week (for 2 weeks). An initial assessment was carried out (T0), another one 1-week after starting the study (T1), and a third one at the end (T2). Results showed significant PFM strength gains in MI and AO groups, but not in the SO group. Regarding lumbo-pelvic motor control, both MI and AO groups obtained statistically significant changes between pre- and post-intervention Additionally, only the AO group showed significant improvements already at 1-week of intervention. Finally, all groups showed improved pain sensitivity in the likely area of referred menstrual pain post-intervention, with only the MI group showing changes 1 week after starting the intervention. In conclusion, results showed that adding MI and AO to PE program leads to an improvement of sensorimotor function of PFM and related structures in general. Despite finding no statistically significant inter-group differences, some findings such as strength gains or the lumbo-pelvic motor control improvements were only found in MI and AO groups, and this should be considered clinically.
主要目的是评估运动想象(MI)和动作观察(AO)加体育锻炼(PE)对盆底及相关结构的影响。44名健康女性随机分为三组:MI组、AO组和假观察组(SO)。结果测量包括盆底肌肉(PFM)状况(包括基底张力和强度)、腰盆腔运动控制和疼痛敏感性。所有妇女以每周3秒的速度进行6次治疗(持续2周)。初步评估(T0),研究开始后1周再进行一次评估(T1),研究结束时进行第三次评估(T2)。结果显示心肌梗死组和AO组PFM强度显著增加,而SO组无明显增加。在腰盆腔运动控制方面,MI组和AO组在干预前和干预后均有统计学意义的变化。此外,只有AO组在干预1周时已经有了显著的改善。最后,所有组在干预后可能涉及的月经疼痛区域的疼痛敏感性都有所改善,只有MI组在干预开始1周后出现变化。综上所述,在PE方案中加入MI和AO可改善PFM及相关结构的感觉运动功能。尽管没有发现组间差异有统计学意义,但一些发现如力量增加或腰盆腔运动控制改善仅在MI组和AO组中发现,这应在临床上予以考虑。

An external focus of attention, enhanced expectancies, and autonomy support (i.e., OPTIMAL factors) are key factors to optimise motor performance and uncover latent movement capabilities. However, research on the combination of OPTIMAL factors, particularly in children's dynamic movement settings is limited. Therefore, this study examined the combined effects of OPTIMAL factors on children's performance on a dynamic movement assessment battery, hypothesising higher performance scores in the optimised version of the assessment battery versus standardised version of the assessment. Forty-nine children (15 boys, 34 girls; mean age 10.61 ± 1.38 years) completed the Dragon Challenge (DC) dynamic movement assessment battery. Performance was measured via a summation of movement process (technique), outcome, and time-to-completion scores (max score N = 54) with higher scores representing better performance. Participants completed a standardised and an optimised version of the DC in a counterbalanced fashion. For the latter, DC protocols were optimised via the provision of choice (autonomy support); external focus instructions augmented by simple knowledge statement, positive feedback and promotion of a growth mindset (Enhanced expectancies). Results indicate that motor performance (DC score) was better in the optimised (M = 31.08 ± 6.66) vs. standardised (M = 29.04 ± 5.88). The findings indicate that the combination of OPTIMAL factors can improve children's motor performance in dynamic movement settings and that standardised motor assessment may not reveal children's true movement capabilities.
外部关注焦点、增强的预期和自主支持(即 OPTIMAL 因素)是优化运动表现和发掘潜在运动能力的关键因素。然而,有关 OPTIMAL 因素组合的研究,尤其是在儿童动态运动环境中的研究还很有限。因此,本研究考察了 OPTIMAL 因素对儿童动态运动评估表现的综合影响,并假设优化版的评估表现得分要高于标准化版的评估表现得分。49 名儿童(15 名男孩,34 名女孩;平均年龄为 10.61 ± 1.38 岁)完成了 "龙挑战"(Dragon Challenge,DC)动态动作评估测试。成绩通过动作过程(技巧)、结果和完成时间分数的总和来衡量(最高分 N = 54),分数越高代表成绩越好。参赛者以平衡方式完成了标准化和优化版的 DC。在后者中,通过提供选择(自主支持)、简单的知识陈述、积极反馈和促进成长心态(增强预期)来优化 DC 方案。结果表明,优化(M = 31.08 ± 6.66)与标准化(M = 29.04 ± 5.88)相比,运动表现(DC 分数)更好。研究结果表明,结合优化因素可以提高儿童在动态运动环境中的运动表现,而标准化运动评估可能无法揭示儿童的真实运动能力。

Previous research suggests that affective factors may influence perception of potential movement differently compared to perception during movement itself. To build on this the current study investigated the roles of general and movement-specific anxiety, self-efficacy, general resilience and motor control in how 41 adults with typical motor skills thought they would behave (perceptual judgement) and how they actually behaved (executed action). Participants completed several standardised scales and two movement-specific scales, a perceptual judgement task and an executed action task. In the perceptual judgement task participants judged whether they would need to turn their shoulders to walk through different sized apertures between 0.9 and 1.9 their shoulder width-to-aperture ratio. This involved a static (standing still) and a dynamic (walking towards) condition. The executed action task involved actually walking through the different sized gaps between the doors. Findings were discussed within an ecological framework drawing strongly on Newell's constraints-based approach (1986). Results indicated a relationship between higher movement-specific anxiety and bigger safety margins. This highlights the importance of measure specificity in being able to detect nuanced relationships between affective factors and the perception-action cycle. Notable differences were also shown in the point of behaviour change (critical ratio) between perceptual judgement and executed action, illustrating the importance of studying perception and action together since they can be subject to different constraints. The findings contribute novel insights into the roles of these factors in how adults with typical motor skills perceive and realise their intentions and abilities to act in the world.
以往的研究表明,与运动过程中的感知相比,情感因素可能会对潜在运动的感知产生不同的影响。在此基础上,本研究调查了一般焦虑和特定运动焦虑、自我效能感、一般复原力和运动控制在 41 名具有典型运动技能的成年人如何看待他们的行为(知觉判断)和他们如何实际行动(执行动作)中的作用。受试者完成了几个标准化量表和两个特定动作量表、一个感知判断任务和一个执行动作任务。在知觉判断任务中,受试者要判断自己是否需要转动肩膀才能通过肩宽与孔径比为 0.9 到 1.9 之间的不同大小的孔径。这包括静态(站立不动)和动态(朝前走)两种情况。执行的行动任务包括实际穿过门之间不同大小的缝隙。研究结果在生态学框架内进行了讨论,主要借鉴了纽厄尔的基于约束的方法(1986 年)。结果表明,较高的特定动作焦虑与较大的安全裕度之间存在关系。这凸显了测量特异性在检测情感因素与感知-行动循环之间细微关系中的重要性。感知判断和执行行动之间的行为变化点(临界比率)也存在显著差异,这说明了将感知和行动结合起来研究的重要性,因为它们可能会受到不同的限制。这些发现有助于深入了解这些因素在具有典型运动技能的成年人如何感知和实现他们在世界上行动的意图和能力方面所起的作用。

This study investigated the acute effects of barefoot (BF) running on biomechanical parameters and cytokine concentrations. Seventy-one habitually shod runners had biomechanical parameters evaluated during running shod (SH) and BF, while a sub-group of 19 runners had their inflammatory profile analyzed before and after a running session, using their habitual shoes or barefoot. Running BF changed spatiotemporal and joint kinematics, including the stride frequency (increased) and length (decreased), and foot strike pattern (more plantarflexed ankle at initial contact). An increased impact force was observed (p < 0.05), while joint moment, power, and work were also affected by BF running: a shift of joint load from the knee and hip to the ankle occurred (p < 0.05). In cytokine levels, maintenance (all cytokines, except Eotaxin, IL-12p40, IL-2, IL5, and MIP-1 beta) or reductions (IL-12p40, IL-2, and IL5) were observed as an acute response to BF running, what means to keep or reduce the levels of pro-inflammatory cytokines and immunological/chemoattraction proteins when compared to SH. Summarily, a single session of BF running may not represent enough stress to induce changes in the inflammatory profile. Besides the increased impact force, the joint load was reduced during short-term BF running. Nevertheless, short-term BF running should be cautiously applied due to the shift of joint load from the knee and hip to the ankle.

Falls are a significant health risk in older adults, and forward and backward falls each account for more than 40 % of falls. Dynamic stability, limb support, and impact energy absorption are crucial balance regulatory components and likely vary with the direction of imbalance. Understanding how perturbation direction influences these key components of balance stability regulation is crucial. This study investigated the balance stability, lower limb impact energy absorption, and limb support in forward and backward directions of balance perturbations in younger versus older adults.
Thirteen healthy old and thirteen healthy young adults participated in this study. Participants stood on two adjacent perturbation platforms in modified tandem stance. The leading or trailing limb support surface dropped 76.2 mm vertically at an unknown time to impose body shift. Two-way (direction X group) mixed ANOVA was performed to analyze the anterior margin of stability (MoS), trunk angular displacement, peak negative power at the hip, knee, and ankle, and the peak vertical ground reaction forces (VGRF).
Compared to forward perturbation, backward perturbation induced greater MoS (P < 0.01), peak VGRF (P < 0.01), and peak ankle (P < 0.05) and hip (P < 0.05) joint power. Older adults showed decreased MoS (P < 0.05), perturbed limb peak VGRF (P < 0.05), and ankle (P < 0.05) and knee (P < 0.05) joint peak power compared to younger adults.

Vertical ground reaction force (vGRF) is a main kinetic gait analysis explaining body weight loading patterns. The study primarily aimed to understand effects of Freezing of gait (FoG) on vGRF in Parkinson's disease (PD). A secondary analysis for a walking dataset including biomechanical analyses for 26 PD participants (13 with FoG) was performed. Considering the normal pattern of vGRF curve, peaks during early stance (F1) and late stance (F3), and slope in- during mid-stance (F2) were used to represent the change in kinetic forces. vGRF parameters were compared between FoG and non-FoG participants, and at off- and on-medication. FoG participants showed higher vGRFs during mid-stance F2 magnitude (p = 0.003), and weaker vertical propulsion; F3 magnitude (p < 0.001). This coincided with delayed weight acceptance; F1 timing (p = 0.019), and midstance peaks; F2 timing (p = 0.004). At off-medications, the F2 magnitude was significantly higher (p = 0.006), F3 magnitude lower (p = 0.001), and F1 time slower (p = 0.034) in FoG. At on-medication, F3 magnitude was still significantly lower (p = 0.017), and F2 time was slower (p = 0.037) in FoG. This study reveals that FoG significantly affects vGRF, particularly F3 magnitude during the push-off phase. Analyzing vGRF is crucial for understanding and managing FoG, allowing for more targeted interventions to improve FoG outcomes.
垂直地面反作用力(vGRF)是解释体重负荷模式的主要运动步态分析方法。本研究的主要目的是了解帕金森病(PD)患者步态冻结(FoG)对 vGRF 的影响。研究还对 26 名帕金森病患者(其中 13 人患有 FoG)的步行数据集进行了二次分析,包括生物力学分析。考虑到vGRF曲线的正常模式,早期站立(F1)和晚期站立(F3)时的峰值以及中期站立(F2)时的斜率被用来表示运动力的变化。FoG 参与者在中段站立时表现出更高的 vGRF,F2 幅值(p = 0.003),而垂直推进力较弱;F3 幅值(p < 0.001)。这与体重接受延迟(F1 时间)(p = 0.019)和中段站立峰值(F2 时间)(p = 0.004)相吻合。在非药物治疗时,FoG 的 F2 幅值明显更高(p = 0.006),F3 幅值更低(p = 0.001),F1 时间更慢(p = 0.034)。在用药时,FoG 的 F3 幅值仍然明显较低(p = 0.017),F2 时间较慢(p = 0.037)。本研究揭示了 FoG 对 vGRF 的显著影响,尤其是在推离阶段的 F3 幅值。分析 vGRF 对了解和管理 FoG 至关重要,可以采取更有针对性的干预措施来改善 FoG 的结果。

Background

Recent studies suggest that muscle synergy patterns can be a guide for diagnosis and rehabilitation.

Research question

Does human's lower limb synergy pattern significantly change with changes in walking speed? Are there large differences in synergy patterns among different healthy individuals?

Methods

22 healthy subjects from an open-source datasets were included. Non-negative matrix factorization was applied to identify the module composition of surface electromyography(sEMG) data, and the similarity index was adopted to quantify the overall similarity between synergy patterns.

Results

Results demonstrated that healthy individuals have their own intrinsic muscle recruitment and coordination characteristics for locomotion at various speeds, additionally, their synergy patterns exhibit predictability under speed variations.

Significance

This study develop reference synergy patterns for the lower limbs across 28 different walking speeds. The developed synergy patterns and the above findings may guide the study of gait synergy in rehabilitation and assistance.

Objectives

To investigate the effect of concentric fatigue on proprioception, motor control and performance of the shoulder in healthy young adults.

Design

Test-retest experimental design.

Setting

Human performance laboratory.

Participants

20 healthy adults.

Main outcome meausure(s)

Proprioception was assessed using the joint repositioning sense (JRS) and the threshold to detection of passive movement (TTDPM). Motor control was assessed using the Y-balance Upper Quarter test (YBT-UQ) and performance using the Athletic Shoulder test (ASH test). All tests were conducted before and immediately after fatigue intervention (CON/CON protocol).

Results

Following fatigue, absolute angular error (AAE) was significantly increase by 160.27 %. Moreover, there was a significant increase (48.41 %) in TTDPM after fatigue. Furthermore there was no significant differences in motor control and performance before and after fatigue intervention.

Conclusions

Since muscular fatigue negatively affects shoulder proprioception, it is essential to assess proprioception before and after fatigue to detect any dysfunctions that may arise as a result of fatigue. To address these dysfunctions, it is recommended to engage in proprioceptive exercises under situations of fatigue in order to enhance the sensitivity of the mechanoreceptors.
目的:研究同心疲劳对健康青壮年本体感觉、运动控制和肩部表现的影响:研究同心疲劳对健康年轻人肩部本体感觉、运动控制和表现的影响:设计:重复测试实验设计:参与者:20 名健康成年人:用关节复位感(JRS)和被动运动检测阈值(TTDPM)评估运动感觉。运动控制能力通过Y型平衡上四分之一测试(YBT-UQ)进行评估,运动能力则通过运动肩测试(ASH测试)进行评估。所有测试均在疲劳干预之前和之后立即进行(CON/CON 方案):结果:疲劳后,绝对角度误差(AAE)显著增加了 160.27%。此外,疲劳后 TTDPM 也明显增加(48.41%)。此外,疲劳干预前后的运动控制和表现没有明显差异:由于肌肉疲劳会对肩部本体感觉产生负面影响,因此有必要在疲劳前后对本体感觉进行评估,以发现疲劳可能导致的任何功能障碍。为了解决这些功能障碍,建议在疲劳状态下进行本体感觉练习,以提高机械感受器的灵敏度。
