<p class="ResumoAbstract">The aim of this study was to compare the learning process of a postural control task between post-stroke patients and healthy subjects. The sample was composed of 20 post-stroke individuals (Experimental Group) and 20 aged matched healthy individuals (Control Group). Participants practiced a postural control task in a virtual environment with increasing of complexity. The study design involved four phases: pre-test (five trials), acquisition phase (four blocks of thirty minutes), post-test (five trials), and retention test (five trials after a week without practice). The statistical analysis was run by a 2 x 3 ANOVA (groups x learning tests). Results: There was no difference in motor learning between Experimental Group and Control Group (F= 41.22; p=0.88). In addition, it was founded that the Control Group could learn the task in a higher-level complexity than Experimental Group (F = 4.77; p = 0.01), and both groups increased the error during the trials of practice (F = 0.53; p = 0.00) because of task complexity.  Conclusion: Therefore has been found that post-stroke individuals have the ability to learn a postural control task similar to healthy subjects, and the task complexity seems to be a key-factor in order to differentiate stroke from healthy subject's motor learning process.</p>

Brain damage pathology can generate an irrelevant motor program leading to abnormal posture. Given this observation, we tested the hypothesis that postural control deficits are present in individuals with postural disorders. A new trunk sway assessment protocol evaluation system using an inertial-based sensing technique combined with visual-biofeedback strategies was developed. The proposed system was used to assess the angular deviation of the center of mass and enhanced balance control in patients with stroke. Twelve participants with hemiplegia were randomly divided into a visual-biofeedback group (experimental) and a without visual-biofeedback group (control), and were asked to stand as still as possible for 30 s. Postural sway data were submitted to conventional quantitative analyses of sway magnitude using a center of mass measurement. Additionally, group means were compared using parametric tests. Parameters in both the anterior-posterior and medio-lateral directions within the stroke patients were compared using paired t-tests. The experimental group showed increased postural control, indicative of reduced postural sway. Decreased complexity in the medio-lateral direction was also observed in the experimental group, suggesting both a reduction in the dynamic range available for postural control, and that their postural corrections were dominated primarily by longer-term scales. Significant interactions between the diagnostic group and visual condition were also observed for both of these measures, suggesting that the control group participants were impaired in their ability to make corrections to their sway pattern when no visual biofeedback was available. Greater sway magnitude and reduced complexity suggest that individuals with hemiplegia have deficits in sensorimotor integration and a reduced range of timescales available within which to make postural corrections.

Background: Stroke is one of the major healthcare challenges, being one of the leading causes of death, disability, and dependency in the activity of daily living worldwide Homecare of stroke patients is having a great role in the patient recovery. Patient family caregivers and relatives can play an important role in the care of patients. But how to continue proper care of the patient at home after discharge, they don't know what to do and don't have practice as well. In this view, the researcher believes that it might be a great help for caregivers and the patients to teach theirs about stroke and home care of stroke patients. Objective: The study aims to evaluate the effectiveness of a planned health teaching on the caregiver's knowledge and competence of home care of stroke patients. Therefore, improve the patients' functional ability. Methods: The two group pre and post-test, quasi-experimental design was conducted among 50 caregivers of stroke patients, assigned to 25 caregivers as a control group and 25 caregivers as an experimental group. The study was done in the university hospital at El Fayoum city from 1st March 2019 to 31st August 2019. Four tools were used for data collection after reviewing relevant data as the following; a structured interviewing questionnaire, caregiver's knowledge questionnaire regarding stroke, caregiver's practices regarding bed position, Position Change and Transfer, and Range of Motion Exercises, and patient function ability assessment according to Barthel index. Results: revealed that there was a poor score level of knowledge and competence of home care practices before the intervention. However, there was an improvement of score level in the control and experimental group post-intervention, but the higher score was observed in the experimental group. The mean score level of patient functional ability in the experimental group improved than the control group through follow up. Highly statistical significance was found between control and experimental group post-intervention related to knowledge and practices. A positive significant correlation between caregiver's practices and patients function ability in the experimental group was found. Conclusion: planned health teaching is important after patients discharge to increase the caregiver's knowledge and competence of home care practices of post-stroke patients; resulting in improved patient functional ability.

Background: Stroke patients with motor, sensory and cognitive diseases can take profits from information and communication technologies—in particular, from the latest commercial video consoles, which are based on motion capture. These technologies are positioning themselves as complementary therapeutic tools for treating gait and balance disorders. In this paper, a systematic review of the effect of video game-based therapy on balance and gait in stroke patients is shown and compared with other types of treatments. Methods: A systematic review of prospective controlled clinical trials published in the main biomedical databases in English and Spanish between 2005 and 2020 was performed. The systematic review presented in this paper has been done following the Cochrane Manual recommendations and the PRISMA Declaration by two independent reviewers. Data about participants, intervention, outcome measurements and outcome measurement results were extracted. The quality of evidence of each study was assessed using Cochrane’s standard quality assessment format, which includes a description of the risk of bias. Additionally, the Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of each paper. Results: A total of 18 papers, including 479 patients, were included in this systematic review, in which the use of video consoles (in combination with conventional rehabilitation or exclusively) was compared with conventional rehabilitation to treat balance or gait in post-stroke patients. In all studies, a tendency to improve balance was found in both intervention groups, finding, in 10 of 17 studies that analysed it, a better capacity in the experimental group that included video consoles compared to the conventional rehabilitation control group. Regarding gait, in six of seven studies that analysed it, improvements were found in both intervention groups, and these improvements were greater in the experimental group than compared to the control group in three of them. Conclusions: Commercial video game systems, in combination with conventional rehabilitation, have shown positive results on balance and gait in post-stroke patients. There were variations between the trials in terms of the video consoles used and the duration, frequency and number of sessions with commercial video games. Future studies should compare the effects of commercial video game treatments on balance and gait in stroke patients with a nonintervention group to know their real efficacy.

The article deals with the state of cognitive functions (memory, attention and thought process) and asthenic disorders in stroke patients in the process of physical rehabilitation and pharmacotherapy. The study used conventional methods for determining the state of cognitive functions. To improve cognitive abilities in the process of physical rehabilitation in the experimental group of patients, traditional methods and special physical exercises in the form of training tasks for memory, attention and thought processes were used. In the control group of patients only traditional methods of restoration of cognitive functions were used. Both groups of patients took the same drugs to improve cognitive function and relieve symptoms of cerebrogenic asthenia, using classic nootropic drugs (Pyracetam, Phenotropil, Vinpotropil), peptide drugs (Cortexin, Cerebrolysin, Noopept, Semax), antidepressants and tranquilizers (benzodiazepines and non-benzodiazepine). It is determined that the most important indicator of memory quality is short-term memory. In the experimental group in the process of physical rehabilitation revealed an improvement in this memory in 50% of patients, the deterioration of this indicator in 34% of persons, and 16% memory remained at the same level. Short-term memory indices in post-stroke patients of the control group are lower and correspond to: improvement – in 35%, deterioration – in 40%, remained at the same level in 25% of patients. Since the rate of short-term memory is 7 ± 2 units of information, the study showed that in all patients after a stroke, the indicators of storing information in short-term memory have become normal. The study of attention stability revealed that in the control group of patients it is worse than in the experimental group, and that the stability of attention does not depend on the experience of the post-stroke state. Patients with 3 years of post-stroke experience show the same results as patients with 6-month stroke. The study of inductive thinking showed that in both groups of patients it is in good condition. As for the indicators of practical mathematical thinking, 83% of the participants coped with the task in the experimental group, and 17% failed. In the control group, 57% of patients coped with this task, and 43% failed. Only 50% of the patients in the experimental group and 42% of the control group coped with a more difficult task in this type of thinking. The same results were obtained in persons without stroke. This shows that the more difficult tasks of identifying this type of thinking are difficult for people after a stroke. It can be concluded that the mental processes of a person after a stroke are in optimal condition.

Objective: To explore the effect of cluster nursing care among post-stroke patients. Methods: Post-stroke patients with dysphagia (n=72) were randomly divided into two groups: experimental (or intervention) (n=36) the control (n=36). Patients in the experimental group were given cluster care, including swallowing assessment, safe eating guide, swallowing rehabilitation, the establishment of cluster prevention strategy and health education to patients and caregivers. Patients in the control group were given conventional nursing care, and the score of swallowing function, the prevalence of aspiration pneumonia and nursing care satisfactory level in both groups were assessed before and after the intervention. Results: The swallowing function of patients in the two groups were improved after intervention, but patients in the experimental group showed significantly higher improvement than the control group (P<0.05). The incidence of aspiration pneumonia was significantly lower in the experimental group compared to the control group (P<0.05). Moreover, the satisfactory level of nursing management was higher in the experimental group than the control group (P<0.05). Conclusion: Cluster nursing (CN) practice has significantly improved the swallowing function of stroke patients with dysphagia, reduced the incidence of aspiration pneumonia and enhanced the satisfaction of nursing care.

People who survive a stroke are often left with long-term neurologic deficits that induce, among other impairments, balance disorders. While virtual reality (VR) is growing in popularity for postural control rehabilitation in post-stroke patients, studies on the effect of challenging virtual environments, simulating common daily situations on postural control in post-stroke patients, are scarce. This study is a first step to document the postural response of stroke patients to different challenging virtual environments. Five subacute stroke patients and fifteen age-matched healthy adults were included. All participants underwent posturographic tests in control conditions (open and closed eyes) and virtual environment without (one static condition) and with avatars (four dynamic conditions) using a head-mounted device for VR. In dynamic environments, we modulated the density of the virtual crowd (dense and light crowd) and the avoidance space with the avatars (near or far). Center of pressure velocity was collected by trial throughout randomized 30-s periods. Results showed that more challenging conditions (dynamic condition) induced greater postural disturbances in stroke patients than in healthy counterparts. Our study suggests that virtual reality environments should be adjusted in light of obtaining more or less challenging conditions.

AbstractThe objective of this article is to analyze the didactic functionality of a chatbot to improve the results of the students of the National University of Distance Education (UNED / Spain) in accessing the university in the subject of Spanish Language. For this, a quasi-experimental experiment was designed, and a quantitative methodology was used through pretest and posttest in a control and experimental group in which the effectiveness of two teaching models was compared, one more traditional based on exercises written on paper and another based on interaction with a chatbot. Subsequently, the perception of the experimental group in an academic forum about the educational use of the chatbot was analyzed through text mining with tests of Latent Dirichlet Allocation (LDA), pairwise distance matrix and bigrams. The quantitative results showed that the students in the experimental group substantially improved the results compared to the students with a more traditional methodology (experimental group / mean: 32.1346 / control group / mean: 28.4706). Punctuation correctness has been improved mainly in the usage of comma, colon and periods in different syntactic patterns. Furthermore, the perception of the students in the experimental group showed that they positively value chatbots in their teaching–learning process in three dimensions: greater “support” and companionship in the learning process, as they perceive greater interactivity due to their conversational nature; greater “feedback” and interaction compared to the more traditional methodology and, lastly, they especially value the ease of use and the possibility of interacting and learning anywhere and anytime.

AbstractMotor learning interacts with and shapes experience-dependent cerebral plasticity. In stroke patients with paresis of the upper limb, motor recovery was proposed to reflect a process of re-learning the lost/impaired skill, which interacts with rehabilitation. However, to what extent stroke patients with hemiparesis may retain the ability of learning with their affected limb remains an unsolved issue, that was addressed by this study. Nineteen patients, with a cerebrovascular lesion affecting the right or the left hemisphere, underwent an explicit motor learning task (finger tapping task, FTT), which was performed with the paretic hand. Eighteen age-matched healthy participants served as controls. Motor performance was assessed during the learning phase (i.e., online learning), as well as immediately at the end of practice, and after 90 min and 24 h (i.e., retention). Results show that overall, as compared to the control group, stroke patients, regardless of the side (left/right) of the hemispheric lesion, do not show a reliable practice-dependent improvement; consequently, no retention could be detected in the long-term (after 90 min and 24 h). The motor learning impairment was associated with subcortical damage, predominantly affecting the basal ganglia; conversely, it was not associated with age, time elapsed from stroke, severity of upper-limb motor and sensory deficits, and the general neurological condition. This evidence expands our understanding regarding the potential of post-stroke motor recovery through motor practice, suggesting a potential key role of basal ganglia, not only in implicit motor learning as previously pointed out, but also in explicit finger tapping motor tasks.

Context: Neuromuscular training enhances unconscious motor responses by stimulating both the afferent signals and central mechanisms responsible for dynamic joint control. Dynamic joint-control training is a vital component of injury-prevention programs. Objective: To investigate the effects of body-weight neuromuscular training on Y-Balance Test (YBT) performance and postural control in female basketball players. Design: Randomized controlled clinical trial. Setting: Basketball practice sessions. Patients or Other Participants: A total of 28 healthy elite female basketball players were randomly assigned to an experimental (n = 14) or a control group (n = 14). Intervention(s): Before their regular practice sessions, the experimental group warmed up with body-weight neuromuscular exercises and the control group with standard tactical-technical exercises twice weekly for 8 weeks. Main Outcome Measure(s): Anterior-, posteromedial-, and posterolateral-reach and composite YBT scores were measured before and after 8 weeks of training. Results: Improvement over baseline scores was noted in the posteromedial (right = 86.5 ± 4.5 cm versus 89.6 ± 2.2 cm, +3.5%, P = .049; left = 85.5 ± 4.3 cm versus 90.2 ± 2.7 cm, +5.5%, P = .038)- and posterolateral (right = 90.7 ± 3.6 cm versus 94.0 ± 2.7 cm, +3.6%, P = .016; left = 90.9 ± 3.5 cm versus 94.2 ± 2.6 cm, +3.6%, P = .011)-reach directions and in the composite YBT scores (right = 88.6% ± 3.2% versus 94.0% ± 1.8%, +5.4%, P = .0004; left = 89.2% ± 3.2% versus 94.5% ± 3.0%, +5.8%, P = .001) of the experimental group. No differences in anterior reach were detected in either group. Differences were noted in postintervention scores for posteromedial reach (right = 89.6 ± 2.2 cm versus 84.3 ± 4.4 cm, +4.1%, P = .005; left = 94.2 ± 2.6 cm versus 84.8 ± 4.4 cm, +10%, P = .003) and composite scores (right = 94.0% ± 1.8% versus 87.3% ± 2.0%, +7.1%, P = .003; left = 94.8% ± 3.0% versus 87.9% ± 3.4%, +7.3%, P &lt; .0001) between the experimental and control groups. Conclusions: Body-weight neuromuscular training improved postural control and lower limb stability in female basketball players as assessed with the YBT. Incorporating neuromuscular training into the workout routines for basketball players may enhance joint awareness and reduce the risk of lower extremity injury.

Abstract Background: Real-time ultrasound imaging (RUSI) has been increasingly used as a form of biofeedback when instructing and re-training muscle contraction. However, the effectiveness of the RUSI on a single sustained contraction of the lumbar multifidus (LM) and transversus abdominis (TrA) has rarely been reported. This preliminary study aimed to determine if the use of RUSI, as visual biofeedback, could enhance the ability of activation and continuous contraction of the trunk muscles including LM and TrA.Methods: Forty healthy individuals were included and randomly assigned into the experimental group and control group. All subjects performed a preferential activation of the LM and/or TrA (maintained the constraction of LM and/or TrA for 30 seconds and then relaxed for two minutes), while those in the experimental group also received visual feedback provided by RUSI. The thickness of LM and/or TrA at rest and during contraction (Tc-max, T15s, and T30s) were extracted and recorded. The experiment was repeated three times.Results: No significant differences were found in the thickness of LM at rest (P > 0.999), Tc-max (P > 0.999), and T15s (P = 0.414) between the two groups. However, the ability to recruit LM muscle contraction differed between groups at T30s (P = 0.006), with subjects in the experimental group that received visual ultrasound biofeedback maintaining a relative maximum contraction. Besides, no significant differences were found in the TrA muscle thickness at rest (P > 0.999) and Tc-max (P > 0.999) between the two groups. However, significant differences of contraction thickness were found at T15s (P = 0.031) and T30s (P = 0.010) between the two groups during the Abdominal Drawing-in Maneuver (ADIM), with greater TrA muscle contraction thickness in the experimental group.Conclusions: RUSI can be used to provide visual biofeedback, which can promote continuous contraction, and improve the ability to activate the LM and TrA muscles in healthy subjects.
