We investigated fatigue and performance rates as decision-making criteria in pacing control during CrossFit®. Thirteen male regional-level competitors completed conditions of all-out (maximum physical work from beginning to end) and controlled-split (controlled physical work in the first two rounds but maximum work in the third round) pacing throughout the Fight Gone Bad workout separated by one week. We assessed benchmarks, countermovement jumps and ratings of fatigue after each round. Benchmarks were lower in round 1 (99 vs. 114, p < .001) but higher in rounds 2 (98 vs. 80, p < .001) and 3 (97 vs. 80, p < .001) for controlled-split compared with all-out pacing. Reductions in countermovement jumps were higher after rounds 1 (−12.6% vs. 1.6%, p < .001) and 2 (−12.7% vs. −4.0%, p = .014) but similar after round 3 (−13.2% vs. −11.3%, p = .571) for all-out compared with controlled-split pacing. Ratings of fatigue were higher after rounds 1 (7 vs. 5 a.u., p < .001) and 2 (8 vs. 7 a.u, p = .023) but similar after round 3 (9 vs. 9 a.u., p = .737) for all-out compared with controlled-split pacing. During all-out pacing, countermovement jump reductions after round 2 correlated with benchmark drops across rounds 1 and 2 ( r = .78, p = .002) and rounds 1 and 3 ( r = −.77, p = .002) and with benchmark workout changes between pacing strategies ( r = −.58, p = .036), suggesting that the larger the countermovement jump reductions the higher the benchmark drops across rounds and workouts. Therefore, benchmarks, countermovement jumps and ratings of fatigue may assess exercise-induced fatigue as decision-making criteria to improve pacing strategy during workouts performed for as many repetitions as possible.

我们研究了在 CrossFit® 运动中将疲劳度和成绩率作为控制步速的决策标准。13 名地区级男子选手在 "Fight Gone Bad "训练中完成了全力以赴（从开始到结束的最大体力消耗）和控制分段（前两轮控制体力消耗，但第三轮最大限度地消耗体力）两种步调条件，时间间隔为一周。我们对每轮训练后的基准、反跳动作和疲劳程度进行了评估。与全力以赴的步调相比，第一轮的基准较低（99 vs. 114，p < .001），但第二轮（98 vs. 80，p < .001）和第三轮（97 vs. 80，p < .001）的基准较高。在第一轮（-12.6% vs. 1.6%，p <.001）和第二轮（-12.7% vs. -4.0%，p = .014）之后，反向跳跃的减少率较高，但在第三轮（-13.2% vs. -11.3%，p = .571）之后，全速前进与控制分步前进的减少率相近。在第一轮（7 a.u. 对 5 a.u.，p = 0.001）和第二轮（8 a.u. 对 7 a.u.，p = 0.023）之后，对疲劳的评分较高，但在第三轮（9 a.u. 对 9 a.u.，p = 0.737）之后，全力起搏与控制分割起搏的疲劳评分相近。在全速起搏过程中，第 2 轮后反运动跳跃的减少与第 1 和第 2 轮（r = .78，p = .002）和第 1 和第 3 轮（r = -.77，p = .002）的基准下降以及起搏策略之间的基准锻炼变化（r = -.58，p = .036）相关，这表明反运动跳跃减少的幅度越大，跨轮和跨锻炼的基准下降幅度就越高。因此，基准、反运动跳跃和疲劳评级可以评估运动引起的疲劳，作为在尽可能多重复的锻炼中改进步调策略的决策标准。

A reliable, versatile means of assessing visuo-motor reaction time (V-MRT) is important to football (soccer) players for many reasons, including the fact that faster V-MRT is a critical sport skill that may even play a role in reducing common sports injuries to the lower muscle extremities that can be associated with lost time on the field. We aimed to determine the test-retest reliability and minimum detectable change (MDC) of the Brain Pro System for assessing lower-extremity V-MRT in young male football players. We had 68 participants ( M age = 16.35, SD = 1.71 years) perform two assessment sessions one-week apart. For test-retest reliability, we calculated a one-way intra-class correlation coefficient (ICC) at the 95% confidence interval and provided the standard error of measurement (SEM) and minimum detectable change (MDC) (MDC = SEM × 1.96 × √2) for V-MRTs. We obtained excellent V-MRT test-retest reliability for dominant lower-extremity, non-dominant lower-extremity, and dominant and non-dominant lower-extremities (ICC2,1 = .93, 95%CI = .89–.96; ICC2,1 = .94, 95%CI = .91–.96; ICC2,1 = .96, 95%CI = .94–.97; respectively). The calculated MDC for the dominant lower-extremity V-MRT, the non-dominant lower-extremity V-MRT, and dominant and non-dominant lower-extremities (random) V-MRT were 1.21 seconds, 1.13 seconds, and 1.21 seconds, respectively. Brain Pro System had excellent reliability for assessing lower-extremity V-MRT in young male football players. The MDC values at the 95% confidence level (MDC95) we obtained were reliable for assessing clinically meaningful V-MRT changes.

对足球运动员来说，一种可靠、通用的视觉运动反应时间（V-MRT）评估方法非常重要，原因有很多，其中包括更快的视觉运动反应时间是一项关键的运动技能，它甚至可以在减少常见的下肢肌肉运动损伤方面发挥作用，而这种损伤可能会导致在球场上失去比赛时间。我们的目的是确定 Brain Pro 系统在评估年轻男性足球运动员下肢 V-MRT 时的重复测试可靠性和最小可检测变化（MDC）。我们让 68 名参与者（中位年龄 = 16.35 岁，标准差 = 1.71 岁）进行了两次评估，每次间隔一周。对于重测可靠性，我们计算了 95% 置信区间的单向类内相关系数 (ICC)，并提供了 V-MRT 的测量标准误差 (SEM) 和最小可检测变化 (MDC)（MDC = SEM × 1.96 × √2）。我们对优势下肢、非优势下肢、优势下肢和非优势下肢的 V-MRT 测试-再测可靠性都取得了极佳的结果（ICC2,1 = .93，95%CI = .89-.96；ICC2,1 = .94，95%CI = .91-.96；ICC2,1 = .96，95%CI = .94-.97；分别）。优势下肢 V-MRT、非优势下肢 V-MRT、优势和非优势下肢（随机）V-MRT 的计算 MDC 分别为 1.21 秒、1.13 秒和 1.21 秒。Brain Pro 系统在评估年轻男性足球运动员的下肢 V-MRT 方面具有极佳的可靠性。我们获得的置信度为 95% 的 MDC 值（MDC95）可用于评估具有临床意义的 V-MRT 变化。

Our primary objective in this study was to psychometrically evaluate the Transformational Parenting Questionnaire (TPQ) within the Turkish context. Secondarily, we aimed to determine whether the questionnaire demonstrated measurement invariance across children’s genders and grade levels. We included 950 participants, aged 11–18 years (446 girls, 498 boys, 6 unspecified gender identity; Mage = 14.73, SD = 1.85 years). Confirmatory factor analysis provided support for the original 4-factor structure of the TPQ, and there was satisfactory criterion-related correlational validity between this instrument and the Satisfaction with Life Scale. The TPQ exhibited robust internal item reliability coefficients, and respondent’s test-retest correlations over a 15-day interval suggested adequate item response consistency. Importantly, we confirmed measurement invariance of the scale across participants gender and educational grade levels. In summary, we found that the TPQ was a valid and reliable tool for assessing Turkish children’s perceptions of transformative parenting behaviors.

本研究的主要目的是在土耳其对变革型父母养育问卷（TPQ）进行心理评估。其次，我们还想确定该问卷在不同性别和年级的儿童中是否表现出测量不变性。我们共纳入了 950 名 11-18 岁的参与者（女孩 446 人，男孩 498 人，6 人性别身份不明；年龄 = 14.73 岁，SD = 1.85 岁）。确认性因子分析为 TPQ 最初的 4 因子结构提供了支持，该工具与生活满意度量表之间的标准相关效度令人满意。TPQ显示出稳健的内部项目信度系数，受访者在15天内的测试-再测试相关性表明项目反应具有足够的一致性。重要的是，我们证实了该量表在不同性别和不同年级的受测者之间具有测量不变性。总之，我们发现 TPQ 是一种有效且可靠的工具，可用于评估土耳其儿童对变革型养育行为的看法。

The objective of this study was to examine the psychometric properties of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) for young Norwegian children, a scale that is aligned with skills assessed in the Test of Gross Motor Development- Third Edition. We used convenience sampling to recruit 396 Norwegian-speaking children (7–10-year-olds) who completed the PMSC. A confirmatory factor analysis (CFA) confirmed factorial validity for the proposed three-factor model of the PMSC, encompassing measures of self-perceived ball, locomotor, and active play competence. Internal item consistency coefficients of these sub-scales were acceptable, and subsequent measurement invariant analysis found a gender difference such that boys rated their competence higher than girls in running, jumping forward, hitting a ball (racket), kicking, throwing a ball and rope climbing, while girls rated themselves higher, compared to boys, in galloping and skating/blading. Furthermore, there was a slightly better model fit for boys than for girls. Several items were significantly related to children’s age, and the three-factor model exhibited differential age related factor mean differences across older and younger children. Overall, we found the PMSC to have acceptable psychometric properties for confident use in assessing perceived motor competence among 7–10-year-old Norwegian children, though we observed age and gender differences in children’s responses that warrant careful interpretation of results and further research investigation.

本研究的目的是检验挪威幼儿感知运动技能能力图形量表（Pictorial Scale of Perceived Movement Skill Competence，PMSC）的心理测量特性。我们采用方便取样的方法，招募了396名挪威语儿童（7-10岁），他们都完成了 "运动技能能力图示量表"。确认性因素分析（CFA）证实了所提出的PMSC三因素模型的因子有效性，该模型包括自我感觉球、运动和主动游戏能力的测量。这些子量表的内部项目一致性系数是可以接受的，随后的测量不变性分析发现了性别差异，即男孩在跑步、向前跳跃、击球（球拍）、踢球、扔球和爬绳方面的能力评价高于女孩，而女孩在奔跑和滑冰/滑板方面的能力评价高于男孩。此外，男孩的模型拟合度略高于女孩。有几个项目与儿童的年龄有明显的相关性，三因素模型在年龄较大和年龄较小的儿童中表现出不同的年龄相关因素均值差异。总体而言，我们发现 "运动能力知觉问卷 "具有可接受的心理测量特性，可用于评估7-10岁挪威儿童的运动能力知觉，但我们也观察到了儿童回答中存在的年龄和性别差异，这就需要对结果进行仔细的解释和进一步的研究调查。

Single-leg knee crutches are a relatively new, hands-free mobility assistive device with benefits over standard axillary crutches. Our main goal in this study was to evaluate balance ability in a healthy population upon first exposure to the knee crutch device. We had 20 healthy individuals ( M age = 21.1; SD = 1.5 years ) complete baseline static and dynamic balance tests on a force plate, followed by knee crutch fitting, a self-selected duration of ambulation practice, and another round of balance testing while wearing the knee crutch. We used the BTrackS Balance Test (BBT) to measure static balance, and the BTrackS Limits of Stability (BLOS) test to measure dynamic balance, and we created a custom lateral bias score from the BLOS results. On average, participants self-selected 3.1 minutes of ambulation practice. Wearing the knee crutch caused a near doubling of static balance path length and a large reduction in percentile ranking on the BBT. Dynamic balance area was more than halved ( p < .001), with lateral bias scores during the BLOS, indicating that participants heavily favored their non-crutched leg ( p < .001). Our results indicate that static and dynamic balance were significantly altered when wearing the knee crutch, and participants seemed to switch to a single leg stance strategy. Despite these balance changes, participants were quickly ready and willing to complete independent ambulation and balance testing procedures using the single-leg knee crutch.

单腿膝关节拐杖是一种相对较新的免提式助行装置，与标准腋拐相比具有很多优点。本研究的主要目的是评估健康人群首次接触膝拐杖装置时的平衡能力。我们让 20 名健康人（中位年龄 = 21.1 岁；标准差 = 1.5 岁）在测力板上完成基线静态和动态平衡测试，然后安装膝关节拐杖，进行自选时间的行走练习，并在佩戴膝关节拐杖时进行另一轮平衡测试。我们使用 BTrackS 平衡测试（BBT）来测量静态平衡，使用 BTrackS 稳定极限（BLOS）测试来测量动态平衡，并根据 BLOS 的结果创建了自定义的侧向偏差评分。参与者平均自主选择了 3.1 分钟的行走练习。佩戴膝盖拐杖导致静态平衡路径长度增加了近一倍，BBT百分位数排名大幅下降。动态平衡面积减少了一半以上（p <.001），在BLOS中的侧向偏差得分表明，参与者严重偏向于非拐杖腿（p <.001）。我们的研究结果表明，在佩戴拐杖时，静态和动态平衡发生了显著变化，参与者似乎转而采用单腿站立策略。尽管出现了这些平衡变化，但参与者很快就做好了准备，并愿意使用单腿拐杖完成独立行走和平衡测试程序。

Practitioners have begun using motor imagery (MI) for preventing and treating some pelvic floor disorders. Due to requirements for imagining before performing a MI intervention and because there are few instruments available for assessing this specific ability in the pelvic floor musculature, we sought to develop and test a new MI questionnaire, the Kinesthetic Motor Imagery of Pelvic Floor Muscle Contraction Questionnaire (KMI-PFQ). We focused in this study on the development and analysis of the instrument’s factorial structure and internal reliability in a participant sample of 162 healthy Spanish women ( M age = 20.1, SD = 2.2 years). We developed and evaluated the KMI-PFQ’s psychometric properties, finding it to have good internal consistency, with Cronbach’s α = .838, ω coefficient = .839, and an intraclass correlation coefficient = .809, with two factors (“ability” and “mental effort”) explaining 58.36% of response variance. The standard error of measurement was 3.58, and the minimal detectable change was 9.92. No floor or ceiling effects were identified. There was also good convergent validity as seen by statistically significant positive correlations between KMI-PFQ scores and the revised-Movement Image Questionnaire and Vividness of Visual Imagery Questionnaire. There were no statistically significant correlations between KMI-PFQ scores and the Orientation to Life Questionnaire. The KMI-PFQ is a valid and reliable instrument for measuring kinesthetic ability to feel/imagine pelvic floor muscle contractions in healthy Spanish women.

医生们已经开始使用运动想象（MI）来预防和治疗一些盆底疾病。由于在进行 MI 干预之前需要进行想象，而且用于评估骨盆底肌肉这一特定能力的工具很少，因此我们试图开发并测试一种新的 MI 问卷，即骨盆底肌肉收缩运动想象问卷 (KMI-PFQ)。在这项研究中，我们主要针对 162 名健康的西班牙女性（中位年龄 = 20.1 岁，标准差 = 2.2 岁）样本，开发并分析了该问卷的因子结构和内部可靠性。我们开发并评估了 KMI-PFQ 的心理测量特性，发现它具有良好的内部一致性，Cronbach's α = .838，ω系数 = .839，类内相关系数 = .809，其中两个因子（"能力 "和 "脑力"）解释了 58.36% 的反应方差。测量的标准误差为 3.58，可检测到的最小变化为 9.92。没有发现下限或上限效应。KMI-PFQ 分数与修订版运动形象问卷和生动视觉形象问卷之间存在统计学意义上的显著正相关，因此具有良好的收敛效度。KMI-PFQ 分数与生活定向问卷之间没有统计学意义上的相关性。KMI-PFQ 是一种有效且可靠的工具，可用于测量健康西班牙女性感受/想象盆底肌肉收缩的动觉能力。

We developed and evaluated the KMI-PFQ’s psychometric properties, finding it to have good internal consistency, with Cronbach’s α = .838, ω coefficient = .839, and an intraclass correlation coefficient = .809, with two factors (“ability” and “mental effort”) explaining 58.36% of response variance. The standard error of measurement was 3.58, and the minimal detectable change was 9.92. No floor or ceiling effects were identified. There was also good convergent validity as seen by statistically significant positive correlations between KMI-PFQ scores and the revised-Movement Image Questionnaire and Vividness of Visual Imagery Questionnaire. There were no statistically significant correlations between KMI-PFQ scores and the Orientation to Life Questionnaire. The KMI-PFQ is a valid and reliable instrument for measuring kinesthetic ability to feel/imagine pelvic floor muscle contractions in healthy Spanish women.","PeriodicalId":19869,"journal":{"name":"Perceptual and Motor Skills","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140596782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sport commitment describes a psychological attachment to a sport that influences one’s desire or resolve to continue involvement in it. Studying antecedents believed to influence long term commitment to sport among athletes with a disability will help ensure that participants gain those psychosocial and health outcomes from sport participation that benefit quality of life. Our purposes in this study were: (i) to examine the Sport Commitment Model (SCM) in terms of the magnitude of the contribution of antecedent factors (i.e., enjoyment, personal investment, involvement opportunities, social constraints, involvement alternatives) to sport commitment of athletes with disabilities; and (ii) to examine the model structure (i.e., original SCM, mediation, and direct/indirect model) that best reflects an understanding of the sport commitment antecedents for these athletes. A total of 157 adult athletes ( M age = 34.87, SD = 11.78) with physical disabilities from both team and individual sports across the United States, Europe, and Asia completed the Sport Commitment Questionnaire. Data analyses indicated that sport involvement opportunities, followed by personal investment, were the strongest predictors of these athletes’ sport commitments (R2 = .66). Based on the principle of parsimony, the original structural equation model (χ2 (215) = 384.95; RMSEA = .07; CFI = .95; SRMR = .06) was deemed better for understanding the mechanism of sport commitment than the mediation or direct/indirect models. We address implications of applying the SCM to athletes with disabilities, and we offer suggestions for future research.

体育承诺描述的是一种对体育运动的心理依恋，这种依恋会影响一个人继续参与体育运动的愿望或决心。研究被认为会影响残疾运动员长期参与体育运动的前因，将有助于确保参与者从参与体育运动中获得有益于生活质量的社会心理和健康结果。我们进行这项研究的目的是(i) 根据前因因素（即享受、个人投资、参与机会、社会限制、参与选择）对残疾运动员体育承诺的影响程度，研究体育承诺模型（SCM）；以及 (ii) 研究最能反映对这些运动员体育承诺前因因素的理解的模型结构（即原始 SCM、中介模型和直接/间接模型）。来自美国、欧洲和亚洲的 157 名肢体残疾成年运动员（平均年龄 34.87 岁，平均年龄 11.78 岁）填写了运动承诺问卷。数据分析显示，运动参与机会是这些运动员运动承诺的最强预测因素，其次是个人投资（R2 = .66）。根据简化原则，原始结构方程模型（χ2 (215) = 384.95; RMSEA = .07; CFI = .95; SRMR = .06）被认为比中介模型或直接/间接模型更能理解体育承诺的机制。我们探讨了将 SCM 应用于残疾运动员的意义，并对未来的研究提出了建议。

In this study, we explored the immediate and three-month follow-up effects of physical training on physical fitness in children with autism spectrum disorder (ASD). We randomly assigned 20 children with ASD (age 8-11 years) into an experimental group (EG; n = 10) and a control group (CG; n = 10). The EG participated in an 8-week training program involving both strength and proprioceptive exercises (three 60-minute sessions/week), while the CG simply maintained their daily activities. We assessed physical fitness components for each participant at baseline, post-training, and at a 3-month follow-up. The physical training intervention significantly improved physical fitness of these children with ASD in terms of their flexibility (p < .001; 32.46%), lower limbs strength (p = .003; 36.98%), lower body power (p < .001; 41.78%) and functional mobility (p < .001; 25.56%). However, these addition training-induced gains were lost at follow-up for lower limbs strength (p < .001), flexibility (p < .001), and functional mobility (p = .034)). Physical training was effective for improving physical fitness in children with ASD, but the loss of these gains at three months follow-up underscored the need for continuous physical exercise.

在这项研究中，我们探讨了体育训练对自闭症谱系障碍（ASD）儿童体能的直接影响和三个月的后续影响。我们将 20 名自闭症谱系障碍儿童（8-11 岁）随机分为实验组（EG；n = 10）和对照组（CG；n = 10）。实验组参加为期 8 周的训练计划，包括力量和本体感觉练习（每周 3 次，每次 60 分钟），而对照组只需维持日常活动。我们在基线、训练后和 3 个月的随访中对每位参与者的体能进行了评估。通过体能训练干预，这些患有 ASD 的儿童在柔韧性（p < .001; 32.46%）、下肢力量（p = .003; 36.98%）、下肢力量（p < .001; 41.78%）和功能移动性（p < .001; 25.56%）方面的体能得到了明显改善。然而，这些额外训练所带来的收益在随访中消失了，如下肢力量（p < .001）、柔韧性（p < .001）和功能性活动能力（p = .034））。体育训练能有效改善 ASD 患儿的体能，但在三个月的随访中，这些收益消失了，这突出表明需要持续进行体育锻炼。

In this study, we investigated psychometric support for a version of the Multidimensional Assessment of Teamwork in Sport (MATS) that would be suitable for Brazilian athletes. Four translators participated in the back-translation of this instrument from English to Portuguese, two specialists synthesized the Portuguese and English back-translation versions, and 10 experts assessed the questionnaire items and judged their content validity. To evaluate structural validity, we performed confirmatory factor analysis (CFA). We evaluated internal item reliability with a sample of 447 athletes who completed the adapted measure (the MATS-B). Finally, 202 other athletes completed both the MATS-B and a second measure of collective efficacy (CEQS-B) to provide external validity correlates. With these data, the MATS-B now provides valid and reliable data supporting its use with Brazilian athletes in an adapted assessment tool that aligns with the conceptual framework of teamwork in sports.

在这项研究中，我们调查了适合巴西运动员的体育团队合作多维评估（MATS）版本的心理测量学支持。四名翻译参与了该工具从英语到葡萄牙语的回译工作，两名专家对葡萄牙语和英语的回译版本进行了合成，10 名专家对问卷项目进行了评估，并判断了其内容效度。为了评估结构效度，我们进行了确证因子分析（CFA）。我们对 447 名完成改编测量（MATS-B）的运动员样本进行了内部项目信度评估。最后，202 名其他运动员同时完成了 MATS-B 和第二项集体效能测量（CEQS-B），以提供外部效度相关性。有了这些数据，MATS-B 现在可以提供有效、可靠的数据，支持将其用于巴西运动员的适应性评估工具，并与体育运动中团队合作的概念框架保持一致。

Stroke is a significant health problem that may result in long-term functional deficits. Balance and walking problems are among the most common post-stroke deficits, and they may negatively affect quality of life. Our aim in this study was to investigate the effects of cervical mobilization on balance and gait parameters after stroke. Participants were 24 adults (aged 30-65 years), who scored 24 or above on the Standardized Mini-Mental State Exam (MMSE) and no more than 3 on the Modified Rankin scale. Participants were randomly assigned to either an experimental Bobath therapy and cervical mobilization group (n = 12) or a control group who received Bobath therapy and a sham application (n = 12). Both groups received 60 minutes of Bobath therapy three times a week for four weeks; additionally, the experimental group received 15 minutes of cervical mobilization in each session, while the control group received 15 minutes of spinal sham mobilization each session. Pre and post treatment, we assessed all participants' demographic characteristics, gait parameters, balance parameters, and forward head posture values using a clinical data assessment form, spatiotemporal gait analysis (LEGSystm), portable computerized kinesthetic balance device (SportKAT 550), and craniovertebral angle (CVA), respectively. The groups showed no significant differences in their initial demographic and clinical characteristics (age, sex, stroke duration and disability levels.). In comparing changes on variables of interest, we observed significant experimental versus control group improvements in balance parameters except for their left side balance score (right side, left side, forward, backward and total balance scores were significant at p = .003, p = .089, p < .001, p = .022, p < .001, respectively), gait parameters (stride number, stride length, stride time, stride velocity, cadance at p = .007, p = .019, p = .013, p = .005, p = .001, respectively) and CVA (p < .001). Also, there were findings in favor of the experimental group on the modified timed up and go test on walk out, mid turn, walk back and total times (p = .028, p = .001, p = .016, and p = .001, respectively),but not for sit-to-stand time or stand-to-sit time. Clinicians involved in stroke rehabilitation should assess and treat the cervical region to enhance rehabilitation effectiveness.

中风是一种严重的健康问题，可能导致长期的功能障碍。平衡和行走问题是中风后最常见的功能障碍之一，可能会对生活质量产生负面影响。本研究旨在探讨颈椎活动对中风后平衡和步态参数的影响。研究对象为 24 名成年人（30-65 岁），他们在标准化小型精神状态检查（MMSE）中的得分均在 24 分或以上，在修正的兰金量表中的得分不超过 3 分。参试者被随机分配到博巴思疗法和颈椎活动实验组（12 人）或接受博巴思疗法和假应用的对照组（12 人）。两组均接受为期四周、每周三次、每次 60 分钟的博巴思疗法；此外，实验组每次接受 15 分钟的颈椎活动，而对照组每次接受 15 分钟的脊柱假性活动。治疗前和治疗后，我们分别使用临床数据评估表、时空步态分析仪（LEGSystm）、便携式电脑动觉平衡装置（SportKAT 550）和颅椎角（CVA）评估了所有参与者的人口统计学特征、步态参数、平衡参数和前头姿势值。两组患者的初始人口统计学特征和临床特征（年龄、性别、中风持续时间和残疾程度）无明显差异。在比较相关变量的变化时，我们观察到实验组与对照组相比，除左侧平衡得分外，其他平衡参数均有显著改善（右侧、左侧、前进、后退和总平衡得分的显著性分别为 p = .003、p = .089、p < .001、p = .022、p < .001）、步态参数（步数、步长、步幅、步速、步频分别为 p = .007、p = .019、p = .013、p = .005、p = .001）和 CVA（p < .001）。此外，在改良的定时起立行走测试中，实验组在走出去、中途转身、走回来和总时间上的结果也对实验组有利（分别为 p = .028、p = .001、p = .016 和 p = .001），但在坐到站的时间或站到坐的时间上对实验组不利。参与中风康复的临床医生应该对颈椎区域进行评估和治疗，以提高康复效果。
