Objective. The purpose of the study was to observe the effects of executive dysfunction (ED) on gait and postural control during walking after stroke. Methods. In this study, 34 subjects with stroke and ED (8 women and 26 men; age, 55.41 ± 7.89 years; time since stroke onset, 1.3 ± 0.12 months) were recruited. Stroop color-word test (SCWT), 10-meter walk test (10MWT), timed-up-and-go test (TUGT), and gait analysis were evaluated. The correlation among the correct number of Stroop tasks (SCWT-C), the number of time-consuming tasks (SCWT-T), the amount of interference (SIE-M and SIE-T) and posture control, and gait-related parameters was analyzed. Results. The results indicated that SCWT-C was negatively correlated with 10MWT, TUGT, and bilateral symmetry ( P  < 0.05). However, there was no significant correlation between SCWT-C and stride ( P  > 0.05). A significant negative correlation was seen between SCWT-C and bilateral symmetry ( P  < 0.05). There was no significant correlation between SCWT-T and stride ( P  > 0.05). SCWT-T was positively correlated with TUGT, 10MWT, and bilateral symmetry ( P  < 0.05). SIE-T was positively correlated with TUGT and bilateral symmetry ( P  < 0.05). There was no significant correlation between SIE-T and 10MWT or stride ( P  > 0.05). SIE-M was positively correlated with TUGT and bilateral symmetry ( P  < 0.05). There was no significant correlation between SIE-T and 10MWT or stride ( P  > 0.05). Conclusions. ED is closely related to the decline in postural control and the occurrence of falls. In the early phases of stroke rehabilitation, physiotherapists should focus on the patients’ executive function to accelerate the recovery of postural control.

Background: Abdominal Hypopressive Training (AHT) provides postural improvement, and enhances deep trunk muscle activation. However, until recently, there was a lack of scientific literature supporting these statements. The major purpose of this study was to investigate the effect of AHT on posture control and deep trunk muscle function. Methods: 125 female participants aged 18–60 were randomly allocated to the Experimental Group (EG), consisting of two sessions of 30 min per week for 8 weeks of AHT, or the Control Group (CG), who did not receive any treatment. Postural control was measured with a stabilometric platform to assess the static balance and the activation of deep trunk muscles (specifically the Transverse Abdominal muscle (TrA)), which was measured by real-time ultrasound imaging. Results: The groups were homogeneous at baseline. Statistical differences were identified between both groups after intervention in the Surface of the Center of Pressure (CoP) Open-Eyes (S-OE) (p = 0.001, Cohen’s d = 0.60) and the Velocity of CoP under both conditions; Open-Eyes (V-OE) (p = 0.001, Cohen´s d = 0.63) and Close-Eyes (V-CE) (p = 0.016, Cohen´s d = 0.016), with the EG achieving substantial improvements. Likewise, there were statistically significant differences between measurements over time for the EG on S-OE (p < 0.001, Cohen´s d = 0.99); V-OE (p = 0.038, Cohen´s d = 0.27); V-CE (p = 0.006, Cohen´s d = 0.39), anteroposterior movements of CoP with Open-Eyes (RMSY-OE) (p = 0.038, Cohen´s d = 0.60) and activity of TrA under contraction conditions (p < 0.001, Cohen´s d = 0.53). Conclusions: The application of eight weeks of AHT leads to positive outcomes in posture control, as well as an improvement in the deep trunk muscle contraction in the female population.

Hemiplegic gait is the most common sequela of stroke. Patients with hemiplegic gait are at a risk of falling because of poor balance. The theory of cognitive-motor networks paved the way for a new field of research. However, the mechanism of the relationship of cognition with gait or posture control networks is unclear because of the dynamic characteristics of walking and changing postures. To explore differences in the balance function and fall risk between patients with and without cognitive impairment after stroke, we utilized the Berg balance scale, Timed “Up and Go” test, and 10 m walking test. Patients were divided into two groups: the observation group (16 patients, female 6 and male 10), comprising patients with cognitive impairment after stroke, and the control group (16 patients, female 7 and male 9), comprising patients without cognitive impairment after stroke. We found that patients with cognitive impairment had worse balance function and a higher risk of falls. They needed a longer time to turn around or sit down. Our findings indicated that posture control in turning around and sitting down required more cognitive resources in daily life.

Резюме. Правильний і обґрунтований вибір інструментальних методів оцінювання функціо-нального стану пацієнта є обов’язковою умовою адекватної фізичної терапії. Особливе місце цей аспект займає в системі нейрореабілітації пацієнтів з хворобою Паркінсона в Україні, оскільки на сьогодні кількість осіб, що потребують систематичної фізичної терапії, сягає 23 900 тис. Наростаюча маніфестація моторних і немоторних симптомів при хворобі Паркін-сона, від яких часто вирішальною мірою залежить тяжкість стану пацієнта, негативно впливає на якість його життя. Наявні функціональні порушення, які є самостійними проявами хвороби Паркінсона, вимагають специфічного підходу до комплексного інструментального досліджен-ня цих порушень для визначення диференційно-діагностичних критеріїв та оцінювання впливу фізіотерапевтичного втручання. Мета. Проаналізувати наявні інструменти оцінювання впливу фізичної терапії на осіб з хворобою Паркінсона. Методи. Теоретичний аналіз та узагальнення зарубіжних даних спеціальної науково-методичної літератури з питань застосування інстру-ментів оцінювання при хворобі Паркінсона та їх інформативності і надійності у фізичній терапії. Результати. Представлені дані свідчать, що ефективність запроваджених заходів фізичної терапії при хворобі Паркінсона залежить від правильно підібраних інструментів оцінювання, які дозволяють оцінити моторні і немоторні проблеми через призму життєдіяльності і якості життя пацієнта. Основним інструментом оцінювання для вирішення цього питання вважаєть-ся Уніфікована рейтингова шкала хвороби Паркінсона MDS-UPDRS, яка дозволяє об’єктивно оцінити моторні і немоторні аспекти життя пацієнта і його рухову активність. Оскільки наявні моторні й аксіальні рухові порушення негативно впливають на повсякденну функціональну активність пацієнта, для верифікації цих порушень пропонують використовувати тест для оці-нювання часу підйому і ходьби (Timed Up and Go (TUG)); тест з подвійним завданням (Dual-Task TUG (TUG-DT)) та шкалу рівноваги Берга (Berg Balance Scale (BBS)). Але виходячи з того, що ці тести недостатньо чутливі до невеликих змін у рухливості при хворобі Паркінсона, особливо на середніх і пізніх стадіях захворювання, їх доцільно поєднувати з одним із кількісних тестів для оцінювання ходьби: 10-метровим тестом ходьби (10 Meter Walk Test (10MW)) та 6-хвилинним тестом ходьби (Six Minute Walk Distance (6MWT)). Поняття «життєдіяльність» включає в себе не тільки переміщення, її оцінювання має бути доповнено аналізом ступеня впливу наявних по-рушень на повсякденну діяльність, тобто на якість життя пацієнта. Найбільш інформативними інструментами для проведення цього аналізу є універсальні і специфічні при хворобі Паркінсо-на опитувальники з метою оцінювання стану здоров’я SF-36, EuroQOL (EQ-5D) і PDQ-39 (The Parkinson’s Disease Questionnaire). Результати аналізу та узагальнення даних науково-мето-дичної літератури дають підставу встановити, що маніфестація порушень та їх варіабельність при хворобі Паркінсона стають серйозною проблемою у досягненні кінцевого результату за-проваджених заходів фізичної терапії на всіх стадіях захворювання. Використання в комплексі стандартної експертно-реабілітаційної діагностики спеціальних інструментів оцінювання дозволяє об’єктивізувати оцінювання клінічної інформації та стимулює розроблення особисто-орієнтованих реабілітаційних стратегій із застосуванням заходів фізичної терапії, спрямованих на покращення якості життя пацієнтів з хворобою Паркінсона. Ключові слова: хвороба Паркінсона, фізична терапія, якість життя, інструменти оцінювання, достовірність, надійність, валідність.

Background: It has recently been noticed that the quantity of stress affects postural stability in young women. The study was conducted with the goal of investigating whether increased stress may damagingly effect posture control in 90 young men (71 right-handed and 19 left-handed) while maintaining an upright bipedal posture, while keeping their eyes open or closed. Perceived Stress Scale (PSS) was administered and changes in free cortisol levels were monitored (Cortisol Awakening Response, CAR) in order to evaluate the amount of stress present during awakening, while the Profile of Mood States (POMS) was used to estimate distress on the whole. Posture control was evaluated with the use of a force platform, which, while computing a confidence ellipse area of 95%, was engaged by the Center of Pressure through five stability stations and was sustained for a minimum of 52 s, with and without visual input. Another goal of the experiment was to find out whether or not cortisol increases in CAR were linked with rises of blood lactate levels. Results: CAR, PSS and POMS were found to be extensively related. Furthermore, it has been observed that increases in salivary cortisol in CAR are associated with small but significant increases in blood lactate levels. As expected, stress levels did affect postural stability. Conclusions: The results of the present study confirm that the level of stress can influence postural stability, and that this influence is principally obvious when visual information is not used in postural control.

Introduction: Balance in individual with intellectual disability has a great importance due to the failure to perform motor tasks. The purpose of the present study was to compare postural control and balance function in two groups of individual with intellectually disabled with and without developmental coordination disorder. Methods: The present study was a cross-sectional and causal-comparative. The statistical population of this study included all students with intellectually disabilities studying in an exceptional school in Rasht in 2019. According to the inclusion and exclusion criteria, 52 people, including 32 students with intellectual disabilities with developmental coordination disorder and 20 students with intellectual disabilities without developmental coordination disorder were purposefully selected. BESS test, Y balance test, Timed Up and Go (TUG) test were used to evaluate postural control, dynamic balance and functional balance, respectively. For statistical analysis, SPSS version 16 software, independent t-test and Mann-Whitney U tests at a significance level of P <0.05 was used. Results: Based on the results of the present study, a significant difference was observed in functional balance (p = 0.001), and overall score of postural control (p = 0.003), but no significant difference in dynamic balance (p <0.05) was observed between the two groups. Conclusion: Developmental coordination disorder is highly prevalent among the individual with intellectual disabilities. At the same time, they have poorer postural control and functional balance compared to their peers without developmental coordination disorder. Due to the importance of controlling posture and maintaining proper balance in order to prevent injury of these people who are less physically fit than their peers, it is recommended to sports coaches, occupational therapists, physiotherapists and other related fields to take a variety of balance programs to emphasize on improving their balance.

Background: Ageing in women is associated with chronic degenerative pain leading to a functional decrease and therefore increase fall risk. It is therefore essential to detect early functional decreases in the presence of pain related to osteoarthritis. Objective: This cross-sectional study aimed to assess the impact of pain on functionality, postural control and fall risk in women aged between 45 to 64 years old. Methods: Twenty-one (21) women aged 45 to 64 were evaluated by clinical and functional measures such as a pain questionnaire (Lequesne Index), functional tests (Stair Step Test, 5 times sit-to-stand, 6MWD, Timed-up and Go) and postural performance (under force platform). Women were classified into 2 groups from the Lequesne Pain Index (PI): low pain (score ≤ 9) and strong pain (score ≥ 10) for subsequent comparisons on functionality (physical and postural control performance). Results: A significant impact was observed between the pain index (strong PI) and 3 of the 4 functional tests carried out including Stair Step Test (p = 0.001; g = 1.44), walking distance (p = 0.003; g = 1.31) and Timed-up and Go (p = 0.04; g = −0.93). The group with a strong PI score reported further poor postural control under force platform compared to the weak pain group. Conclusion: Pain and severity based on the PI index negatively modulate physical and postural control performance in women aged 45 to 64 years old.

Pseudobulbar affect is a disorder of emotional expression commonly observed in amyotrophic lateral sclerosis (ALS), presenting as episodes of involuntary laughter, or crying. The objective of the current study was to determine the association between frequency of pathological laughter and crying (PLC) episodes with clinical features, cognitive impairment, and brainstem pathology. Thirty-five sporadic ALS patients underwent neuropsychological assessment, with a subset also undergoing brain imaging. The Center for Neurological Study Lability Scale (CNS-LS) was used to screen for presence and severity of pseudobulbar affect (CNS-LS ≥ 13) and frequency of PLC episodes. Presence of pseudobulbar affect was significantly higher in bulbar onset ALS (p = 0.02). Frequency of PLC episodes was differentially associated with cognitive performance and brainstem integrity. Notably pathological laughter frequency, but not crying, showed a significant positive association with executive dysfunction on the Trail Making Test B-A (R2 = 0.14, p = 0.04). Similarly, only pathological laughter frequency demonstrated a significant negative correlation with gray matter volume of the brainstem (R2 = 0.46, p &lt; 0.01), and mean fractional anisotropy of the superior cerebellar peduncles (left: R2 = 0.44, p &lt; 0.01; right: R2 = 0.44, p &lt; 0.01). Hierarchical regression indicated brainstem imaging in combination with site of symptom onset explained 73% of the variance in pathological laughter frequency in ALS. The current findings suggest emotional lability is underpinned by degeneration across distinct neural circuits, with brainstem integrity critical in the emergence of pathological laughter.

Objectives: The purpose of this retrospective study is to further the limited body of evidence regarding the effects of a group-based boxing intervention for those with Parkinson’s disease (PD). Design: A retrospective cohort study was performed analyzing data collected on outcome measures at 6-month intervals up to 2 years. Individuals participated in the standardized “Rock Steady Boxing” (RSB) program for up to 24 months. Every 6 months, measures were taken of balance (Fullerton Advanced Balance [FAB] Scale), functional mobility (Timed-Up and Go [TUG]), lower extremity strength (30-second Chair Stand [30CST]), and gait speed (10 Meter Walk Test [10MWT]). Methods: Statistical significance ( P < .05) was determined by a two-tailed t test. Data were collected from RSB-affiliated programs at 4 locations across the southeastern United States. Current and/or past participants in RSB with baseline and at least one subsequent outcome measure were included, resulting in 68 participants (54 male, 14 female, and mean age of 71.2 years ± 8.56 standard deviation). Results: Statistically significant improvements in FAB scale, TUG, and 30CST over time were found at both 6- and 12-month time points. Significant changes continued through 18 months for FAB and 30CST. No significant changes in 10MWT were observed; however, a moderate effect size was observed at the 1-year point. Conclusions: Participants with PD were able to achieve statistically significant improvements in standard measures of functional mobility, balance, and strength within the timeline of this study. Limitations include the retrospective nature, an inability to monitor adherence, and lack of control over pharmaceutical or other interventions.

Control of standing posture requires fusion of multiple inputs including visual, vestibular, somatosensory, and other sensors, each having distinct dynamics. We propose that postural control also entails a shared neural integrator. To test this theory, we perturbed standing subjects with classic sensory stimuli (optokinetic and galvanic vestibular stimulation) and found that our proposed shared filter reproduces the dynamics of subjects’ postural responses.

IntroductionPatients with schizophrenia commonly show deficits in executive functioning that allow a person to make plans, solve problems, do many tasks simultaneously and adapt to unexpected conditions. Executive dysfunction is associated with very simple and automatic activities, such as walking in schizophrenia patients. However, no study exists about its relation to postural control in these patients.AimTo investigate the effect of executive functioning on postural control using dual task paradigms.MethodsFifteen clinically stable schizophrenia outpatients and 15 healthy controls were enrolled in the study. Postural control was assessed with bilateral stance test using the Balance Master system under three different conditions with eyes open and eyes closed (EC): without a task, during a cognitive task (verbal fluency) and during a motor task (holding a cup of water).ResultsStanding on a foam surface with EC resulted in higher postural sway velocities in schizophrenia patients under all conditions (P = 0.009, P = 0.032, P = 0.013). During a cognitive task, both schizophrenia patients and healthy controls showed higher velocities on firm surface with EC in comparison to the condition without a task (P = 0.023). Both schizophrenia patients and healthy controls did not show higher postural sway velocities during the motor task.ConclusionThe effect of verbal fluency on postural sway shows the relationship between executive functioning and postural control in schizophrenia patients. Foam surface also higher postural sway velocities in schizophrenia patients in EC condition suggesting the difficulties in integrating the proprioceptive information in the absence of visual input.Disclosure of interestThe authors have not supplied their declaration of competing interest.
