<div><h3>Background</h3><div>Amateur athletes frequently experience delayed-onset muscle soreness (DOMS), impacting training and daily activities. Myofascial release, a massage technique for DOMS management, can be performed manually or with instruments. Recently, percussion devices, such as massage guns, have gained popularity. While several studies have examined foam rollers for self-myofascial release, no research has compared physiotherapist-administered manual myofascial release with instrument-assisted or percussion-based techniques for DOMS treatment.</div></div><div><h3>Objective</h3><div>To evaluate the effects of a single session of manual myofascial release alone or combined with instrument-assisted soft tissue mobilization or a percussion device massager on DOMS in amateur athletes.</div></div><div><h3>Methods</h3><div>Randomized controlled trial. Amateur athletes were classified as "very active" according to the International Physical Activity Questionnaire (IPAQ), and pain reporting associated with exercise practice was included. Exclusion criteria included athletes with pain due to a previously diagnosed musculoskeletal injury and those unable to read and understand the questionnaire. Athletes were randomized into one of three groups: Manual Myofascial Release (MMR), Manual + Instrument-Assisted Soft Tissue Mobilization (MMR+IASTM), or Manual + Percussion Device Massager (MMR+PDM). An assistant researcher conducted the randomization process. Assessments were carried out by a trained evaluator blinded to group allocation. Initially, participants identified the muscle group experiencing pain. The evaluator then palpated the affected muscle group and asked the athlete to quantify their pain using the Visual Analog Scale (VAS) from 0 to 10. Following this assessment, a trained physiotherapist administered the assigned intervention. Each session lasted 40 minutes. The session was evenly divided for interventions combining manual therapy with another approach, with 20 minutes allocated to manual therapy and 20 minutes to the instrument/device intervention. Immediately after the session, the same evaluator reassessed pain levels using the VAS. Twenty-four hours later, the research team contacted participants, instructing them to palpate the painful area and self-report their pain score on the VAS. To assess normality, the Shapiro-Wilk test was applied. For group comparisons, repeated measures ANOVA and one-way ANOVA were used.</div></div><div><h3>Results</h3><div>A total of 159 athletes completed the protocol: 73 in the MMR group, 47 in the MMR+IASTM group, and 39 in the MMR+PDM group. There was a loss of 24-hour follow-up data in the last two groups due to non-responsiveness to the 24-hour evaluation. No significant differences were found between the three groups in baseline VAS scores: 4.63 for MMR, 4.79 for MMR+IASTM, and 5.59 for MMR+PDM (p = 0.099).

<div><h3>Background</h3><div>Hearing loss may be associated with lower levels of physical activity, fragmentation of active time, and greater difficulties in performing activities of daily living. However, there are no records of validated exercise tests for the physical assessment of people with deafness, which are crucial for prescribing interventions and monitoring physiological and functional responses. Among these, the Cardiopulmonary Exercise Test (CPET) stands out as the gold standard for assessing physical fitness and limiting symptoms. However, CPET requires expensive equipment, highly trained personnel, and standard laboratory conditions, which limits its wide availability to the general population. On the other hand, the Modified Shuttle Test (MST) is a progressive, standardized, incremental test that is simple to perform in non-laboratory conditions. However, the MST uses auditory stimuli to guide participants, making it unfeasible for people with severe hearing loss or deafness.</div></div><div><h3>Objectives</h3><div>The central objective of this study was to develop an adaptation of the MST guided by visual cues. Secondarily, we intend to test the validity and agreement of the visual TSM.</div></div><div><h3>Methods</h3><div>This is a cross-sectional study, divided into two phases. Phase I includes the development of resources for adapting the TSM, using visual guidance to replace the audible commands of the conventional test. LED (Light Emitting Diode) RGB (Red Green Blue) light signals were used, positioned above each cone, located at the ends of the path. In this phase, the test will be tested on healthy individuals and its agreement, determined by paired t-test, analysis of the intraclass correlation coefficient (ICC) and 95% confidence intervals (CI) and Spearman's correlation coefficient. In Phase II, the feasibility and reproducibility of the adapted TSM in deaf individuals will be tested.</div></div><div><h3>Results</h3><div>An agreement analysis of partial data from Phase I was performed using the ICC (intraclass correlation coefficient) between the auditory SST and the visual SST in hearing individuals, considering the peak HR (n = 8) 170,7 ± 15.8 vs 169,4 ± 11,0bpm (p > 0,05) and the distance covered in the tests (n = 10) 999,0 ± 44,3 vs 987,0 ± 53,1 meters (p > 0,05), respectively. The partial results demonstrate an agreement between the tests for HR with ICC = 0,81 (95% CI = 0,39–0,93) and for distance covered ICC = 0.85 (95% CI = 0,46–0,96). The correlation between the HRpeak of the tests was r = 0,68, and between the distances it was r = 0,76 (p < 0,05 for both).</div></div><div><h3>Conclusion</h3><div>The adapted TSM has good agreement and validity when compared to the conventional TSM.</div></div><div><h3>Implications</h3><div>The results of this study can promote inclusion and accessibility of people with deafness for the assessment of functional capacity, contributing to a more equitable approach in the
背景：听力损失可能与身体活动水平较低、活动时间分散以及在进行日常生活活动时遇到较大困难有关。然而，对于耳聋患者的身体评估来说，没有经过验证的运动测试的记录，而这对于制定干预措施和监测生理和功能反应至关重要。其中，心肺运动测试（CPET）作为评估身体健康和限制症状的黄金标准脱颖而出。然而，CPET需要昂贵的设备、训练有素的人员和标准的实验室条件，这限制了它在普通人群中的广泛可用性。另一方面，改进穿梭测试（MST）是一种渐进的、标准化的、增量的测试，在非实验室条件下很容易执行。然而，MST使用听觉刺激来引导参与者，这对于有严重听力损失或耳聋的人来说是不可行的。本研究的中心目的是开发一种由视觉线索引导的MST适应性。其次，我们打算测试可视化TSM的有效性和一致性。方法本研究为横断面研究，分为两个阶段。第一阶段包括开发适应TSM的资源，使用视觉引导取代传统测试的声音命令。使用LED（发光二极管）RGB（红绿蓝）光信号，位于每个锥体的上方，位于路径的末端。在这一阶段，将对健康个体进行检验，并通过配对t检验、类内相关系数（ICC）、95%置信区间（CI）和Spearman相关系数的分析来确定检验结果的一致性。在第二阶段，将测试适应性TSM在聋人个体中的可行性和可重复性。结果考虑到峰值心率（n = 8）170、7±15.8 vs 169、4±11,0bpm （p > 0.05）和测试所覆盖的距离（n = 10）999、0±44,3 vs 987、0±53,1 m (p > 0.05)，利用听觉SST与视觉SST之间的类内相关系数（ICC）对第一阶段部分数据进行一致性分析。部分结果表明，对于ICC = 0,81 （95% CI = 0,39 - 0,93）和距离覆盖ICC = 0.85 （95% CI = 0,46 - 0,96）的HR测试之间是一致的。试验HRpeak之间的相关性为r = 0,68，距离之间的相关性为r = 0,76（两者的p <； 0.05）。结论与传统TSM相比，改进后的TSM具有较好的一致性和有效性。本研究的结果可以促进聋人功能能力评估的包容性和可及性，有助于在运动处方中采用更公平的方法。此外，我们可以为该人群的心肺健康评估提供一个安全有效的方案。

The intervention consisted of five components: (1) Passive stretching: Low-intensity, sustained stretches of the sternocleidomastoid (SCM) muscle. (2) Active range of motion training: Stimuli for head-righting responses during exercises in various postures. (3) Symmetry-based activities: Encouragement of midline head alignment and equal use of both sides of the body during play. (4) Environmental modifications: Positioning strategies for sleep, feeding, and other activities in the home setting. (5) Caregiver education and adherence monitoring: Weekly supervised sessions (60 minutes) to assess progress, reinforce techniques, and implement an individualized home program for each child based on the criteria of the 2024 Clinical Practice Guideline.

<div><h3>Background</h3><div>Understanding the interaction between musculoskeletal variables is essential for identifying dysfunction, preventing injuries, and improving athletic performance. Ankle dorsiflexion and hip function are crucial for dynamic activities such as jumping. Although the Hop Test is widely used to assess functional capacity, the interaction between these variables and their impact on performance remains underexplored. In this context, asymmetry between the lower limbs can compromise performance and increase the risk of injuries, making it essential to identify and correct these discrepancies to enhance performance and prevent musculoskeletal deficiencies.</div></div><div><h3>Objectives</h3><div>To investigate the correlation of ankle and hip joints mobility and strength asymmetry with the performance of Hop Test in physically active individuals. The study aims to understand how these variables are related with functional capacity and physical performance in activities that require jumping and stability in physically active individuals.</div></div><div><h3>Methods</h3><div>This is a cross-sectional study using data from the Physiotherapy Assessment Tool (PHAST) database. The sample consisted of 200 physically active individuals (124 men, 76 women, 97% with right lower limb dominance), aged 18-56 years (mean = 35.01; SD = 8.71), with an average height of 172.8cm and weight of 72.84kg. Participants underwent the following clinical measurements: passive hip internal rotation (IR) ROM, ankle dorsiflexion ROM, hip extensor and abductors repetition test, and the single Hop Test. Pearson's correlation coefficient and linear regression analysis were performed to examine the associations between asymmetry scores, musculoskeletal variables, and hop test performance, with a significance level set at p < 0.05.</div></div><div><h3>Results</h3><div>Greater asymmetry was observed in ankle dorsiflexion ROM (> 10%) in 42.5% of individuals, in hip extensors repetition test (> 10%) in 51.5% of volunteers, and in hip abduction repetition test (> 10%) in 60% of the sample. Regarding single Hop Test performance, an asymmetry greater than 10% was observed in 27.5% of participants. Although correlations were weak, they were statistically significant between hip extensors function (r = 0.18 and p = 0.009 on the dominant side [DS]; and r = 0.19 and p = 0.005 on the non-dominant side [NDS]) and dorsiflexion ROM (r = 0.19 and p = 0.006 on the DS; and r = 0.19 and p = 0.004 on the NDS) when compared to Hop Test performance.</div></div><div><h3>Conclusion</h3><div>The observed correlations and asymmetries suggest that hip extensors function and dorsiflexion ROM have a significant, albeit weak, relationship with single Hop Test performance.

了解肌肉骨骼变量之间的相互作用对于识别功能障碍、预防损伤和提高运动成绩至关重要。踝关节背屈和髋关节功能对于跳跃等动态活动至关重要。虽然跳跃测试被广泛用于评估功能能力，但这些变量之间的相互作用及其对性能的影响仍未得到充分探讨。在这种情况下，下肢之间的不对称会影响运动表现并增加受伤的风险，因此必须识别和纠正这些差异，以提高运动表现并预防肌肉骨骼缺陷。目的探讨体力活动者踝关节、髋关节活动度和力量不对称性与跳测验成绩的关系。这项研究的目的是了解这些变量是如何与需要跳跃和稳定的体力活动中的功能能力和身体表现相关的。方法：这是一项横断面研究，数据来自物理治疗评估工具（PHAST）数据库。样本包括200名身体活跃的个体（男性124名，女性76名，97%为右下肢优势），年龄18-56岁（平均 = 35.01；标准差 = 8.71），平均身高172.8cm，体重72.84kg。参与者接受了以下临床测量：被动髋关节内旋（IR） ROM，踝关节背屈ROM，髋关节伸肌和外展肌重复测试，以及单跳测试。采用Pearson相关系数和线性回归分析检验不对称得分、肌肉骨骼变量和跳跃测试成绩之间的关系，显著性水平设置为p <； 0.05。结果42.5%的受试者在踝关节背屈测试（> 10%）、51.5%的受试者在髋关节伸肌重复测试（> 10%）和60%的受试者在髋关节外展重复测试（> 10%）中观察到更大的不对称性。关于单跳测试的表现，27.5%的参与者观察到不对称性大于10%。尽管相关性很弱,他们之间统计上显著的臀部两种函数(r = 0.18和0.009 p = 占主导地位的一侧(DS);和r = 0.19和0.005 p = 非惯用一侧(NDS))和背屈罗(r = 0.19和0.006 p = DS;和r = 0.19和0.004 p = NDS)相比,测试性能。结论观察到的相关性和不对称性表明，髋关节伸肌功能和背屈ROM与单跳测试成绩有显著的相关性，尽管相关性较弱。此外，与髋关节外展重复测试、髋关节伸肌重复测试和踝关节背屈ROM相关的变量的不对称性表明，未来研究的重点是可以探索改善对称性和身体表现的干预措施，特别是在涉及跳跃和关节稳定性的活动中。本研究的结果强调了了解髋关节变量和踝关节/足部复合物对跳跃测试成绩的贡献，以及对损伤预防和功能能力改善的重要性。这些发现强调了通过实施预防受伤和优化身体表现的策略来解决功能障碍和不对称的必要性，特别是在需要跳跃和关节稳定性的活动中。

Chronic back pain (CHP) is a prevalent condition in the general population and has been associated with socioeconomic, clinical, and health factors. Despite this, studies with elderly people involving all regions of Brazil are not yet available.
Objectives
To analyze the prevalence and factors associated with chronic back pain in elderly Brazilians.
Methods
This is a cross-sectional study that used data from the 2019 National Health Survey, with 23,144 people aged 60 years or older. The factors associated with CHD were established based on the estimates of odds ratios by the binary logistic regression model, using the Statistical Package for the Social Sciences (SPSS) program, version 27.0.
Results
The prevalence of CHD among elderly Brazilians corresponded to 31.1% (95% CI: 31.0-31.1). The following variables were consolidated as associated factors: male sex (OR: 0.88; 95% CI: 0.87-0.89), age group from 70 to 79 years (OR: 1.16; 95% CI: 1.15-1.16) and 80 years and over (OR: 1.16; 95% CI: 1.15-1.17); lack of education (OR: 1.06; 95% CI: 1.06-1.07), 1 to 4 years of education (OR: 1.47; 95% CI: 1.45-1.48), 5 to 8 years of education (OR: 0.94; 95% CI: 0.93-0.96); income of up to 1 minimum wage (OR: 1.42; 95% CI: 1.40-1.43), 1 to 2 minimum wages (OR: 1.29; 95% CI: 1.28-1.31); absence of partner (OR: 1.16; 95% CI: 1.15-1.16); perception of health as regular (OR: 0.61; 95% CI: 0.60-0.62) and poor/very poor (OR: 1.26; 95% CI: 1.25-1.27); sleep problems (OR: 0.85; 95% CI: 0.84-0.86); presence of multimorbidities (OR: 0.74; 95% CI: 0.73-0.74); use of medications (OR: 3.17; 95% CI: 3.14-3.20); dependence for basic (OR: 0.40; 95%CI: 0.39-0.40) and instrumental activities of daily living (OR: 1.19; 95%CI: 1.18-1.20); body mass index (OR: 1.02; 95%CI: 1.02-1.02); depression (OR: 1.19; 95%CI: 1.18-1.20); and occurrence of falls (OR: 0.63; 95%CI: 0.62-0.63).
Conclusion
The prevalence of CHD was high and associated with socioeconomic, clinical, and health variables.
Implications
The results shown may provide support for the implementation of health actions aimed at elderly Brazilians.

Background
Basketball requires high physical demand, including running, directional changes, and frequent jumping. Jump performance is a key determinant of athletic success, given the sport's specific demands. The jump phases include takeoff, flight, and landing, with the ankle joint playing a crucial role in energy transfer and impact absorption.
Objectives
To evaluate the correlation between ankle dorsiflexion and jump height in basketball athletes.
Methods
This cross-sectional observational study included male basketball players, excluding those with self-reported lower limb pain or injury. Ankle dorsiflexion was assessed using the Lunge Test, in which athletes performed maximal knee flexion while maintaining heel contact with the ground. An inclinometer was positioned 15 cm below the tibial tuberosity to record measurements. The test was performed three times with 30-second intervals, and the average dorsiflexion of both limbs was used for analysis. Jump performance was assessed using a bilateral countermovement jump, measured with a Baiobit® inertial sensor placed at the S1-S2 vertebral level. Three jumps were performed with 30-second intervals, and the highest recorded value was used for analysis. Data normality was verified using the Kolmogorov-Smirnov test, and the correlation between variables was analyzed using Pearson’s correlation coefficient. Statistical analysis was performed using SPSS 20.7.
Results
The study included 51 athletes (age: 20.7 ± 0.4 years; body mass: 78.1 ± 1.94 kg; height: 1.8 ± 0.1 m; BMI: 23.5 ± 0.4 kg/m²; basketball experience: 5.9 ± 0.3 years). A strong, significant positive correlation was observed between dorsiflexion and jump height (r = 0.81; P < 0.001).
Conclusion
Ankle mobility positively influences jump height in basketball athletes.
Implications
These findings suggest that physiotherapists working with basketball players should assess ankle mobility and incorporate strategies to enhance dorsiflexion in training and injury prevention programs.

<div><h3>Background</h3><div>During soccer matches, players frequently adjust kicking effort to modulate ball velocity and meet specific tactical demands. Submaximal kicks are typically used for short passes, while maximal kicks are employed for long passes or goal attempts. In maximal kicks, the trunk plays a crucial role in generating a downward energy flow toward the pelvis and the kicking limb, which may avoid excessive effort and overload at the lower limb. However, how these contributions vary across different kicking effort levels remains unclear.</div></div><div><h3>Objectives</h3><div>This study investigated the kinematic and kinetic adjustments at the trunk, hip, and knee joints of the kicking limb during instep kicks performed at three effort levels.</div></div><div><h3>Methods</h3><div>Forty-four amateur soccer players (age: 23.9 ± 4.8 years) performed kicks at maximal effort, 70-80% of maximal, and 50-60% of maximal. Three-dimensional motion capture was performed at 300 Hz, and ground reaction forces were recorded at 1200 Hz. Kinematic and kinetic data were processed using Visual 3D software.

Background
Swimmers frequently experience upper limb injuries, with shoulder pain being one of the most common, negatively affecting their athletic performance. Functional tests, such as the Upper Limb Rotation Test (ULRT), are widely used in clinical practice to assess these athletes. However, there is still no evidence to support the ULRT's ability to differentiate between asymptomatic swimmers and those with shoulder pain. Therefore, it is essential to investigate the known-group validity of the ULRT in this population.
Objectives
To evaluate the known-group validity of the Upper Limb Rotation Test in swimmers asymptomatic and with shoulder pain.
Methods
This is a cross-sectional study that includes swimmers of both sexes, aged between 12 and 60 years, with at least 1 year of competitive practice, and a minimum of two training sessions per week. This study was approved by Ethics Research Committee. The ULRT was performed with the swimmers in a modified flexion position (on their elbows), close to a wall. They performed trunk rotation and external shoulder rotation at 90° of abduction and external rotation, touching a tape on the wall as quickly as possible for 15 seconds. The athletes performed three trials, and the mean was considered for the analysis. The Shapiro-Wilk test was used to assess the normality of distributions for continuous data, which presented normal distribution. For the known group validity, the ULRT score of the asymptomatic group and those with shoulder pain was compared using an independent samples t-test. The data were analyzed with SPSS software version 23.0.
Results
A total of 50 athletes participated in the study, with 29 (58%) from the asymptomatic group and 21 (42%) from the group with shoulder pain, with a mean age of 30.46 ± 14.27 years, and 27 (54%) were male. For the validity of known groups, there was no statistically significant difference between the asymptomatic group and the group with pain (mean difference: 2.72, 95% CI: -5.87, 0.42, p = 0.08).
Conclusion
The results of this study indicate that the ULRT is unable to differentiate swimmers with shoulder pain from asymptomatic swimmers.
Implications
These findings can assist clinicians in the assessment and management of shoulder pain in swimmers, guiding the selection of more effective assessment tools to identify functional restrictions associated with shoulder pain in this population.
游泳运动员经常经历上肢损伤，肩痛是最常见的一种，对他们的运动表现产生负面影响。功能测试，如上肢旋转测试（ULRT），在临床实践中被广泛用于评估这些运动员。然而，仍然没有证据支持ULRT区分无症状游泳者和肩痛者的能力。因此，有必要研究该人群中ULRT的已知组效度。目的评价无症状肩痛游泳者上肢旋转试验的已知组效度。方法：这是一项横断面研究，包括男女游泳运动员，年龄在12到60岁之间，至少有1年的竞技练习，每周至少两次训练。本研究已获伦理研究委员会批准。在进行ULRT时，游泳者以改良的屈曲姿势（肘部）靠近墙壁。他们在外展和外旋90°时进行躯干旋转和外旋肩部旋转，尽可能快地接触墙上的胶带15秒。运动员进行了三次试验，并考虑平均值进行分析。采用Shapiro-Wilk检验对连续数据进行分布正态性检验，结果为正态分布。对于已知的组效度，使用独立样本t检验比较无症状组和肩痛组的ULRT评分。采用SPSS 23.0软件对数据进行分析。结果共50名运动员参与研究，其中无症状组29人（58%），肩痛组21人（42%），平均年龄30.46±14.27岁，男性27人（54%）。对于已知组的效度，无症状组与疼痛组之间无统计学差异（平均差异：2.72,95% CI: -5.87, 0.42, p = 0.08）。结论本研究结果表明，ULRT无法区分有肩痛的游泳者和无症状的游泳者。这些发现可以帮助临床医生评估和管理游泳者的肩痛，指导选择更有效的评估工具来识别该人群中与肩痛相关的功能限制。
