BACKGROUND: The COVID-19 disease acquired pandemic proportions in 2020. To deal with the scenario, social isolation (SI) was adopted, which configures a lack of contact with people and places. The impediments of this measure, however, can bring risks to older people with Parkinson's disease (PD), such as impairments in gait parameters. AIM: To verify the effects of SI on gait parameters in people with Parkinson's disease. METHOD: Thirty-three people with PD were recruited. Gait assessment was conducted in two periods: February 2020 and March 2022 (before and after the SI, respectively). For that, participants were invited to walk on a 5.74m mat with pressure sensors under two conditions: preferred walking speed and fast walking speed. Three trials were performed for each condition. The gait parameters analyzed were Stride Length, Stride Time, Double Support Time, Stride Velocity, Stride Width, and Cadence. Statistical Analysis was performed by paired t-tests for the comparison of gait parameters between moments (pre and post-SI). RESULTS: In the preferred walking speed condition, the participants reduced their Stride Length (t15 = 3.88, p = 0.001) and Stride Velocity (t15 = 3.63, p = 0.002) in the post-SI period. In the fast-walking speed condition, the participants also reduced their Stride Length (t15 = 3.73, p = 0.002) and Stride Velocity (t15 = 2.86, p = 0.012) in the post-SI period. INTERPRETATION: The SI period reduced the stride length and velocity of people with PD. A possible explanation is the lack of physical activity resulting from this public safety measure.
背景:2019冠状病毒病在2020年达到大流行的程度。为了应对这种情况，采用了社会隔离(SI)，即与人和地方缺乏接触。然而，这项措施的障碍可能会给患有帕金森病(PD)的老年人带来风险，例如步态参数的损害。目的:验证SI对帕金森病患者步态参数的影响。方法:招募33例PD患者。步态评估分两个阶段进行:2020年2月和2022年3月(分别在SI之前和之后)。为此，研究人员邀请参与者在两种条件下——首选步行速度和快速步行速度——在5.74米高的垫子上行走，并安装了压力传感器。每种情况进行了三次试验。步态参数分析包括步幅、步幅时间、双支撑时间、步幅速度、步幅宽度和步幅。统计学分析采用配对t检验比较瞬间(si前和si后)步态参数。结果:在首选步行速度条件下，参与者在si后的步幅长度(t15 = 3.88, p = 0.001)和步幅速度(t15 = 3.63, p = 0.002)均有所减少。在快速步行条件下，参与者在si后的步幅长度(t15 = 3.73, p = 0.002)和步幅速度(t15 = 2.86, p = 0.012)也有所减少。解释:SI期减少了PD患者的步幅和速度。一种可能的解释是，这种公共安全措施导致体育活动的缺乏。

BACKGROUND: Smartphones have become an integral part of our lives, providing a wide range of useful features. However, it is important to address the potential risks of using a smartphone while performing motor tasks. AIM: To investigate the effects of smartphone use on postural control and mobility in young adults during standing or walking activities. METHOD: Forty-five individuals, mean age of 22.1 ± 1.5 years, were enrolled in this study. The impact of using smartphone was assessed during a static (performed on a force platform) and a dynamic (timed up and go) test. The participants were instructed to text a message and talk on the phone while standing or walking. Multiple analyses of variance were applied to verify main effect of task. Effect sizes are reported. Significance was set at 5%. RESULTS: Using a smartphone with a simultaneous motor task had a negative impact on both static and dynamic tests (effect size of 0.820 and 0.788, respectively). Participants were at similar risks when walking while texting messages or talking on the phone. Conversely, when standing, talking on the phone caused greater risks compared to the texting condition. INTERPRETATION: In a sample of young adults, smartphone usage was found to affect the performance of motor tasks. The impact varied depending on whether the participants were walking or standing. Further studies should be conducted to investigate the risks associated with performing motor tasks with a smartphone among different population groups, including older individuals and subjects with physical disabilities.

BACKGROUND: The gait of individuals with Parkinson’s disease (PD) tends to be slower, characterized by narrow and short steps. During the medication, the self-selected gait speed of individuals with PD increases. However, when looking individually at the spatiotemporal parameters of gait, the medication induces different and not always consistent effects. However, the effects of medication and freezing of gait during walking in individuals with PD are unknown. AIM: To analyze the effect of antiparkinsonian medication and freezing of gait (FoG) on spatiotemporal gait parameters in individuals with PD. METHOD: For this purpose, we compared gait parameters in individuals with FoG (freezers, n=11) and without FoG (non-freezers, n=11). Spatiotemporal gait parameters (speed, cadence, step length, step time, step width, stride length, stride time, swing phase, and double support) and clinical scales (parts II and III of the Unified Parkinson’s Disease Rating Scale, Hoehn and Yahr, Montreal Cognitive Assessment questionnaire and Mini-Test scale of Balance Assessment System) were analyzed in two experimental sessions, counterbalanced between individuals: one in the ON medication state (1h after ingestion), and another in the OFF medication state (~12h after the last ingestion). Linear mixed effects models 2-groups X 2-conditions were used. RESULTS: We found that gait speed, stride, and step length were significantly higher in the ON than in the OFF condition for both freezers and non-freezers, and significantly lower in the freezers than in the non-freezers, regardless of the medication state. CONCLUSION: These results indicate that medication improved gait performance equivalently in both freezers and non-freezers.

BACKGROUND: The Mini-Balance Evaluation Systems Test (Mini-BESTest) is an efficient screening tool healthcare professionals use to predict the risk of falls in older adults. However, the Mini-BESTest cutoff scores to classify fallers and non-fallers were established using men and women in the same sample. Considering the higher number and prevalence of falls in older women, it is important to know the Mini-BESTest accuracy and the cutoff score specifically for this population. AIM: We examined the capability and accuracy of the Mini-BESTest for identifying fallers and non-fallers female older adults without neurological impairments and established the cutoff scores according to different age groups. METHOD:Eighty-one female older adults were classified into fallers (n=40) and non-fallers (n=41) groups according to their retrospective history of falls in the last 12 months. Fallers and non-fallers were divided into three age groups according to the following ranges: 65-69 years, 70-74 years, and 75+ years. We used the receiver operating characteristic (ROC) curves to determine the relative performances of the Mini-BESTest score for classifying participants with and without a history of falls. RESULTS: The Mini-BESTest is a good and highly accurate tool for identifying female Brazilian fallers and non-fallers. The Mini-BESTest cutoff scores established to classify fallers and non-fallers female older adults in the different age groups were 26 points for 65-69 years and 24 points for 70-74 years and 75+ years. INTERPRETATION: The Mini-BESTest is an important tool that health professionals in clinical practice can use to estimate the risk of falls for older Brazilian women.

BACKGROUND: Fear of falling (FOF) is related to worse locomotor performance, is a predictor of decline in functionality, and predisposes falls in older adults. It is necessary to investigate how FOF influences locomotor parameters during walking and in obstacle avoidance in older adults. AIM: To investigate the relationship between FOF and the locomotor variables during walking through and obstacle avoidance with different physical characteristics. METHOD: 22 older adults participated in this study and were invited to perform three tasks: 1) Walking Through; 2) Walking with a solid obstacle and 3) Walking with a fragile obstacle. RESULTS: Correlations were found between FOF and following variables: 1) Walking Through: step velocity (r=-0.640, p=0.003), width (r=0.641, p=0.003), double support time (r=0.523, p=0.022); 2) Solid obstacle: step velocity (r=-0.666, p=0.002), length (r=-0.758, p<0.001), foot-obstacle horizontal distance (r=-0.479, p=0.038), right stride velocity (r=-0.534, p=0.019), length (r=-0.522, p=0.022), left stride velocity (r=-0.551, p=0.014), left stride duration (r=0.561, p=0.012); 3) Fragilid obstacle: step velocity (r=-0.629, p=0.004), length (r=-0.556, p=0.014), foot-obstacle distance (r=-0.540, p=0.017), obstacle-foot distance (r=-0.492, p=0.032), right stride velocity (r=-0.583, p=0.009), length (r=-0.498, p=0.030), left stride velocity (r=-0.574, p=0.010), length (r=-0.462, p=0.047), width (r=-0.514, p=0.024), right stride duration (r=0.479, p=0.038), left stride duration (r=0.646, p=0.003). CONCLUSION: The characteristics of the obstacle did not influence the older adults FOF during walking through and obstacle avoidance. Although they adopt predictive and reactive compensatory adaptations in an attempt to make the task safer, these adaptations actually make the task more dangerous and increase the risk of stumbling and falling.

This special issue aims to pay tribute to Professor Lilian Gobbi by discussing the control of gait and posture. Given her extensive dedication to comprehending gait and posture control throughout her life, this issue delves into cutting-edge studies that explore various aspects related to these topics. These aspects encompass mobility and balance performance, kinematics, kinetics, muscle activity, and brain activity analysis under both normal and adaptive conditions. Within this special issue, an array of themes associated with gait and posture control is presented through ten dedicated articles, all of which are intended to honor Professor Lilian Gobbi. Among these, five studies investigated locomotion, while three studies closely examined postural control. Furthermore, two studies took on a dual-tasking, addressing both gait and posture contexts. We would also like to extend our gratitude to the reviewers and members of the editorial board for their invaluable expertise and unwavering dedication in ensuring the utmost quality of research presented in this editorial. The editors of this Special Issue are not only pleased with the contributions made to honor Professor Lilian Gobbi, but also view these contributions as a celebration of scientific collaboration and the significant strides we have taken in advancing our understanding of gait and posture.

BACKGROUND: Balance training has demonstrated a positive effect on older adults. However, the specific types and durations of interventions needed to effectively address postural deficits in aging individuals remain important areas of study. It is crucial to impact their motor performance quickly to bring about changes in postural control. AIM: This study aims to investigate the effect of an acute motor intervention using a balance board called the "Boing" on postural control in elderly individuals. METHOD: Twenty senior women between the ages of 60 and 78 were divided into two groups: Intervention Group (IG, n=10) and Control Group (n=10). Both groups performed a pretest postural task on a force plate, including conditions with feet together, feet apart, and semi-tandem stance. Participants in the IG then underwent the motor intervention on the Boing balance board, which disturbed balance in the antero-posterior and medio-lateral directions, similar to the pretest conditions. After the intervention, a posttest was conducted for both groups using the same procedure as the pretest. One week later, a retention test was performed. Analysis of center of pressure (COP) was conducted, examining total displacement (DOT) and root mean square (RMS) in the antero-posterior and medio-lateral directions. RESULTS: A two-way repeated measures ANOVA revealed that during the posttest phase, there were significant differences between the groups in DOT and ML RMS specifically in the semi-tandem condition. The IG group exhibited lower values. CONCLUSION: The Boing balance board shows promise as a useful apparatus for improving postural control through acute motor intervention.

BACKGROUND: There are reports in the literature showing that the pain alters motor control, whether in static or dynamic conditions. VIEW OF THE PAST: Over the past decades theories have been proposed on how and in what conditions the pain affects motor control. To date, changes in movement control have been identified at both peripheral and central levels, which potentially leads to the emergence of compensatory lesions in the medium and long term. CURRENT STATE: The current state of the art on the understanding of how pain alters movement control has enabled the emergence of preventive exercise protocols and treatment of movement disorders generated by the presence of pain. FUTURE PERSPECTIVE: The application of new data acquisition and analysis technologies will allow the development of effective exercise protocols for pain management.

Background: The eyes are the main gateway of visual information input. Moving the eyes is essential to extract visual information from scenes while performing motor actions. This has helped to explain motor behavior, especially in relation to visual attention mechanisms, gaze training and learning, and the relevance of visual information in controlling actions. Thus, collecting data on gaze behavior has become important for explaining motor behavior. Aim: We present the main video-based eye-tracking techniques, briefly describing the anatomy of the eyes, explaining the operation of the eye-tracker (eye capture techniques, calibration, and data analysis), and proposing interpretations of the main variables extracted by the technique. In this way, we carry out considerations (limitations and advantages) on the eye-tracking technique that placed gaze behavior data in the vitrine of human movement science. Interpretation: Eye-tracking has become an excellent tool to assist in the analysis of human movement through gaze behavior. Mainly by combining sensory information, such as visual information, with performance during motor tasks, it is possible to infer about perception, cognition, and human behavior during the most diverse day-to-day activities. Eye-tracker systems have been employed in different majors related to motor behavior, such as medicine, commerce, and game development.

Developmental Coordination Disorder (DCD) is a common neurodevelopmental disorder characterized by motor coordination difficulties that affect academic achievement and everyday activities1, and clearly outlined in the DSM-51 and ICD-102. The prevalence of children with DCD is 2-20%, with 5-6% being the most prevalent rate in the literature3. Common co-occurring disorders are attentiondeficit hyperactivity disorder, autism spectrum disorder, dyslexia, learning disabilities, and language impairments4. The goal of this infographic is to provide an overview of the main characteristics of DCD, diagnosis, and consequences in children's lives.
