RESUMO

Balance can be a main factor contributing to success in many disciplines, and biathlon is a representative example. A more stable posture may be a key factor for shooting scores. The center of foot pressure (COP) is commonly recorded when evaluating postural control. As COP measurements are highly irregular and non-stationary, non-linear deterministic methods, such as entropy, are more appropriate for the analysis of COP displacement. The aim of our study was to investigate whether the longitudinal effects of biathlon training can elicit specific changes in postural control. Eight national-level biathletes, 15 non-athletes who prior to the experiment took part in 3 months of shooting training, and 15 non-athletes with no prior rifle shooting experience took part in our study. The data was collected with the use of a force plate. Participants performed three balance tasks in quiet standing, the shooting position (internal focus-participants concentrated on maintaining the correct body position and rifle), and aiming at the target (external focus-participants concentrated on keeping the laser beam centered on the targets). Biathletes obtained significantly lower values of sample entropy compared to the other groups during the shooting and aiming at the target trials (p<0.05). External and internal focuses influenced the process of postural control among participants who had prior rifle shooting experience and the control group; they obtained significantly higher values of sample entropy while shooting and aiming at the target compared to the quiet standing trial (p<0.05). The biathletes obtained significantly lower values of sample entropy in the aiming at the target position compared to the quiet standing trial. Specific balance training is associated with the ability to deal with a more challenging, non-specific task. The biathletes seemed to employ a different motor control strategy than the beginners and control group, creating repeating patterns (more regular signal for COP) to keep one's balance during the shooting and aiming at the target positions.

RESUMO

In recent years, the amount of publications related to the study of spine using ultrasound, especially on scoliosis, has rapidly increased. Many new methods and application related to 3D ultrasound imaging for scoliosis assessment have been recently reported. The capabilities of three-dimensional (3D) ultrasound to visualize the vertebrae features such as spinous and transverse processes, bilateral laminae and ribs mainly at the level of main thoracic and thoracolumbar region are shown in this chapter. Different ultrasound systems developed for scoliosis evaluation and application of ultrasound during different postures and treatments such as brace fitting are also introduced. Moreover, innovative measurement methods for spinal evaluation in orthogonal planes are presented in this chapter. The advance of the development of 3D ultrasound allows one to perform large-scale screening, prognosticate and diagnose mild and severe scoliosis at a more frequent and non-ionizing basis. The authors wish that this chapter will help to promote the applications of ultrasound to medical specialists in different aspects regarding the possibilities of ultrasonography to tackle with different spinal problems.

RESUMO

BACKGROUND: Exercise can reduce the negative effects of aging on postural control. The slackline training could potentially be an activity to improve postural control in older adults. However, the effects of slackline on postural control in older adults are not clear. This systematic review aimed to investigate the effects of slackline on postural control in older adults. METHODS: Randomized controlled trials were retrieved from ISI Web Knowledge, PubMed and Scopus using the descriptors "Slackline", "Slacklining", "Aged", "Aging", "Elderly", "Older adults", "Balance", "Postural Balance" and "Postural Control". Randomized controlled trials were selected. Postural control was evaluated through center of pressure (CoP), and slackline standing time during single leg stance. RESULTS: Four studies with 118 participants were included. The studies found that slackline improves slackline standing time in the tandem, and the single-legged postures, without differences in CoP displacement in single-leg position, results that were confirmed by the meta-analyses. CONCLUSION: Although slackline training improves task-specific performance, this improvement is not transferable to other tasks. This conclusion should be interpreted with caution considering the small number of studies, inconsistent designs, and general study limitations. Further studies are required before recommending slackline training to optimize the postural control of older adults.

RESUMO

INTRODUCTION: Postural changes frequently occur in pre-adolescent girls, with sedentary lifestyle with reduced physical activity level as one of the risk factors. OBJECTIVE: To investigate the effects of Eutonia, Holistic Gymnastics, and Pilates on body posture in pre-adolescent girls. METHODS: A randomized prospective quantitative clinical trial was conducted. The study included girls aged 10-13 years and compared the effects of Eutonia, Holistic Gymnastics, and Pilates on body posture. The sample comprised 80 girls divided into three intervention groups as follows: Eutonia group, 26 girls; Holistic Gymnastics group, 27 girls; and Pilates group, 27 girls. Ten sessions of 1 h each were conducted on a weekly basis. Static posture was analyzed using the Postural Analysis Software SAPO; dynamic posture, using the modified Layout for Assessing Dynamic Posture LADy; and lifestyle, using the Body Posture Evaluation Instrument Back PEI questionnaire. The data were statistically analyzed using the analysis of variance (ANOVA) by Kruskal-Wallis' averages test at 5% significance level (p < 0,05). RESULTS: The results showed that the three body movement practices improved the head inclination in the frontal plane (1,49°) and pelvic anteversion in the right (1,9°) and left profiles (2,09°). In addition, 25% of pre-teens started to carry their school bag correctly, improving their posture. CONCLUSION: The body movement practices of Eutonia, Holistic Gymnastics, and Pilates improved head inclination, pelvic anteversion, and the correctness rate of carrying the schoolbag.

RESUMO

BACKGROUND: We aimed to obtain the standard values of age-related changes in the activation timing of postural muscles to the prime mover muscle (anterior deltoid [AD]) for bilateral arm flexion during standing. METHODS: The study participants were 276 children (aged 3-14 years) and 32 adults (aged 20-26 years). In response to a visual stimulus, participants raised both arms from a fully extended position as quickly as possible, stopped their arms voluntarily at a horizontal level at the shoulder, and maintained that position for 2 s. Ten test trials were performed. By using surface electromyography, the duration from the burst onset of the postural muscles to that of AD was measured as the starting time of the postural muscles (rectus abdominis [RA], erector spinae [ES], rectus femoris [RF], biceps femoris [BF], tibialis anterior [TA], gastrocnemius medialis [GcM], and soleus [SOL]). The starting time was presented as a negative value when the burst onset of the postural muscles preceded that of AD, which was defined as the preceding activation. A positive value for the starting time was defined as delayed activation. RESULTS: In adults, the burst onsets of ES and BF significantly preceded that of AD. In ES, the starting time preceded the onset of AD in those aged ≥ 5-6 years; no difference with adults was found at age 13-14 years. On the other hand, in BF, significant delayed activation was found at ages 3-4 to 11-12 years. While the starting time decreased with age, no significant preceding activation similar to adults was found, even at age 13-14 years. In TA, no significant difference with the onset of AD was found at age 3-6 years, and significant delayed activation was found at age ≥ 7-8 years. Significant delayed activation in GcM, SOL, RA, and RF was observed in all age groups, and no age-related changes were observed in children. CONCLUSION: These findings could provide standard values from childhood to adolescence for age-related changes in anticipatory postural muscle activity during voluntary movement while standing and contribute to applications in the fields of sports and rehabilitation.

RESUMO

In this study, the performance of a two-dimensional Hénon map in predicting the interactive dynamics of the knee and hip joints emerging during a normative sit-to-stand movement was evaluated. The instantaneous values of the knee and hip joints were the model inputs, and the next values of the knee and hip joints were predicted by the Hénon map. The map predicted the desired relative behavior of the joints, showing synergetic coordination between the joints. The experimental data were recorded from four healthy participants and used to identify the Hénon map via a genetic algorithm. Model performance was quantitatively assessed by computing the calculated prediction error and analyzing the behavioral dynamics of the state spaces reconstructed via the captured kinematic data. According to the results, there was an obvious similarity between the dynamics of the state space trajectories of the identified model and those of the recorded data, not only in terms of stretching and folding dynamics, but also concerning generalized synchrony. The acceptable performance of the proposed modeling solution can also be demonstrated through these results.

RESUMO

BACKGROUND: Previous studies have addressed the effects of different exercises and modalities on forward head posture (FHP), but the minimal clinically important difference (MCID) of the effect of exercises on FHP remains unclear. Therefore, this study aimed to investigate the effects of selective corrective exercises (SCEs) on the craniovertebral angle (CVA) and shoulder angle (SA) in students with FHP and to establish MCID for these angles. METHODS: In this randomized clinical trial study, a total of 103 second-grade male students with FHP were enrolled. Participants were randomly assigned to experimental and control groups. CVA and SA of participants were measured before and after the 8-week selective corrective exercise program (including strengthening and stretching exercises). The photogrammetric method was used to measure CVA and SA. MCID value was calculated for CVA and SA using the distribution method. RESULTS: The results showed that there was a significant difference between the experimental and control groups in terms of CVA (F = 89.04, P = 0.005, Effect size = 0.47) and SA (F = 18.83, P = 0.005, Effect size = 0.16). After eight weeks of selective corrective exercises, the MCID values of CVA and SA were 1.40° and 1.34°, respectively. CONCLUSION: This study revealed that the selective corrective exercises might lead to postural correction of students having FHP problem. Results further indicated that a corrective exercise program would be considered beneficial if it increased CVA and SA values at least 1.40 and 1.34 degrees, respectively.

RESUMO

Abvims and Dr Rml Hospital, Delhi In unilateral pleural effusion it is necessary to find the best position for unilateral pleural effusion so that recovery can be hastened. There is scarcity of literature on the effect of body positional variations on oxygenation, and current guidelines do not address the necessity. The objective of this study is to assess the effect of body position and size of pleural effusion on oxygenation status in spontaneously breathing patients with unilateral pleural effusion. MATERIAL: This was a hospital based observational cross-sectional study having a sample size of 90 patients of unilateral pleural effusion and on the basis of severity, they were divided into 2 classes- small and large. Ipsilateral and Contralateral oxygenation were analysed separately in small and large effusions using Mann-Whitney and Wilcoxon signed rank test and final analysis was made using SPSS software. OBSERVATION: It was observed that oxygenation was better when patient lies on contralateral side in small effusion (PaO2 82.4±8.83 vs 85.01±8.24 p value <0.0001) while in cases of large effusion, oxygenation was better on ipsilateral side of effusion (82.35±10.4 vs 78.06±9.92, p value<0.0001). No significant difference was noted in case of PaCO2 levels in small and large effusion in ipsilateral and contralateral position. It was also noted that there was a significant difference in oxygen saturation. CONCLUSION: There is significant effect of body position and size of pleural effusion on oxygenation status in spontaneously breathing patient with unilateral pleural effusion.

RESUMO

OBJECTIVES: This study aimed to investigate the association between kyphotic posture and future loss of independence (LOI) and mortality in community-dwelling older adults. DESIGN: Prospective cohort study. SETTING: Two Japanese municipalities. PARTICIPANTS: We enrolled 2193 independent community-dwelling older adults aged≥65 years at the time of their baseline health check-up in 2008. Kyphotic posture was evaluated using the wall-occiput test (WOT) and classified into three categories: non-kyphotic, mild (>0 and ≤4 cm) and severe (>4 cm). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was mortality and the secondary outcomes were LOI (new long-term care insurance certification levels 1-5) and a composite of LOI and mortality. A Cox proportional hazards model was used to estimate the adjusted HRs (aHRs). RESULTS: Of the 2193 subjects enrolled, 1621 were included in the primary analysis. Among these, 272 (17%) and 202 (12%) were diagnosed with mild and severe kyphotic postures, respectively. The median follow-up time was 5.8 years. Compared with the non-kyphotic group, the aHRs for mortality were 1.17 (95% CI 0.70 to 1.96) and 1.99 (95% CI 1.20 to 3.30) in the mild and severe kyphotic posture groups, respectively. In the secondary analysis, a consistent association was observed for LOI (mild: aHR 1.70, 95% CI 1.13 to 2.55; severe: aHR 2.08, 95% CI 1.39 to 3.10) and the LOI-mortality composite (mild: aHR 1.27, 95% CI 0.90 to 1.79; severe: aHR 1.83, 95% CI 1.31 to 2.56). CONCLUSION: Kyphotic posture was associated with LOI and mortality in community-dwelling older adults. Identifying the population with kyphotic posture using the WOT might help improve community health.

RESUMO

BACKGROUND: Non-specific low back pain in children and adolescents has increased in recent years. The purpose of this study was to upgrade the evidence of the most effective preventive physiotherapy interventions to improve back care in children and adolescents. METHODS: The study settings were children or adolescents aged 18 years or younger. Data were obtained from the Cochrane Library, MEDLINE, PEDro, Web of Science, LILACS, IBECS, and PsycINFO databases and the specialized journals BMJ and Spine. The included studies were published between May 2012 and May 2020. Controlled trials on children and adolescents who received preventive physiotherapy for back care were considered. Data on all the variables gathered in each individual study were extracted by two authors separately. Two authors assessed risk of bias of included studies using the RoB2 and quality of the body of evidence using the GRADE methodology. Data were described according to PRISMA guidelines. To calculate the effect size, a standardized mean difference "d" was used and a random-effects model was applied for the following outcome variables: behaviour, knowledge, trunk flexion muscle endurance, trunk extension muscle endurance, hamstring flexibility and posture. RESULTS: Twenty studies were finally included. The most common physiotherapy interventions were exercise, postural hygiene and physical activity. The mean age of the total sample was 11.79 years. When comparing the change from baseline to end of intervention in treatment and control groups, the following overall effect estimates were obtained: behaviour d+ = 1.19 (95% CI: 0.62 and 1.76), knowledge d+ = 1.84 (0.58 and 3.09), trunk flexion endurance d+ = 0.65 (-0.02 and 1.33), trunk extension endurance d+ = 0.71 (0.38 and 1.03), posture d+ = 0.65 (0.24 and 1.07) and hamstrings flexibility d+ = 0.46 (0.36 and 0.56). At follow-up, the measurement of the behaviour variable was between 1 and 12 months, with an effect size of d+ = 1.00 (0.37 and 1.63), whereas the knowledge variable obtained an effect size of d+ = 2.08 (-0.85 and 5.02) at 3 months of follow-up. CONCLUSIONS: Recent studies provide strong support for the use of physiotherapy in the improvement of back care and prevention of non-specific low back pain in children and adolescents. Based on GRADE methodology, we found that the evidence was from very low to moderate quality and interventions involving physical exercise, postural hygiene and physical activity should be preferred.

RESUMO

As we stand upright, perceptual afferences are crucial to successfully help generating postural motor commands. Non-Specific Low Back Pain patients frequently demonstrate a lack of proprioceptive acuity, often translating into postural control deficiencies. For the first time, to our knowledge, we studied the postural effects of proprioceptive manipulations in orthograde posture on Non-Specific Low Back Pain patients. Using static posturography recordings, we computed sway speed, speed variance, and the main direction of sway. We also addressed the patient's subjective feedbacks after being manipulated. Five minutes after the proprioceptive manipulations, our results revealed decreased speed and speed variance outcomes, but the main direction of sway was not modulated. Furthermore, after the proprioceptive manipulations, the patients also self-reported improved clinical outcomes. These findings provide new knowledge opening new fields of research as well as potential treatment strategies in Low Back Pain patients.

RESUMO

A gait feature analysis method based on AlphaPose human pose estimation fused with sample entropy is proposed to address complicated, high-cost, and time-consuming postoperative rehabilitation of patients with joint diseases. First, TensorRT was used to optimize the inference of AlphaPose, which consists of the target detection algorithm YOLOv3 and the pose estimation algorithm. It can speed up latency and throughput by about 2.5 times while maintaining the algorithm's accuracy. Second, the optimized human posture estimation algorithm AlphaPose_trt was used to process gait videos of healthy people and patients with knee arthritis. The joint point motion trajectories of the two groups were extracted, and the sample entropy algorithm quantified the joint trajectory signals for feature analysis. The experimental results showed significant differences in the entropy of the heel and ankle joint motion signals between healthy people and arthritic patients (p < 0.01), which can be used to identify patients with knee arthritis. This technique can assist doctors in determining needed postoperative joint surgery rehabilitation.

RESUMO

Human Action Recognition (HAR) is a rapidly evolving field impacting numerous domains, among which is Ambient Assisted Living (AAL). In such a context, the aim of HAR is meeting the needs of frail individuals, whether elderly and/or disabled and promoting autonomous, safe and secure living. To this goal, we propose a monitoring system detecting dangerous situations by classifying human postures through Artificial Intelligence (AI) solutions. The developed algorithm works on a set of features computed from the skeleton data provided by four Kinect One systems simultaneously recording the scene from different angles and identifying the posture of the subject in an ecological context within each recorded frame. Here, we compare the recognition abilities of Multi-Layer Perceptron (MLP) and Long-Short Term Memory (LSTM) Sequence networks. Starting from the set of previously selected features we performed a further feature selection based on an SVM algorithm for the optimization of the MLP network and used a genetic algorithm for selecting the features for the LSTM sequence model. We then optimized the architecture and hyperparameters of both models before comparing their performances. The best MLP model (3 hidden layers and a Softmax output layer) achieved 78.4%, while the best LSTM (2 bidirectional LSTM layers, 2 dropout and a fully connected layer) reached 85.7%. The analysis of the performances on individual classes highlights the better suitability of the LSTM approach.

RESUMO

Human posture equipment technology has advanced significantly thanks to advances in deep learning and machine vision. Even the most advanced models may not be able to predict all body joints accurately. This paper proposes an adaptive generative adversarial network to improve the human posture detection algorithm in order to address this issue. GAN is used in the algorithm to detect human posture improvement. The algorithm uses OpenPose to detect and connect keypoints and then generates heat maps in the GAN system model. During the training process, the confidence evaluation mechanism is added to the system model. The generator predicts posture, while the resolver refines human joints over time. And, by using normalization technologies in the confidence evaluation mechanism, the generator can pay more attention to the prominent body joints, improving the algorithm's body detection accuracy of nodes. In MPII, LSP, and FLIC datasets, the proposed algorithm has shown to have a good detection effect. Its positioning accuracy is about 95.37 percent, and it can accurately locate the joints of the entire body. Several other algorithms are outperformed by this one. The algorithm described in this article has the best simultaneous runtime in the LSP dataset.

RESUMO

With the explosive growth of the number of sports videos, the traditional sports video analysis method based on manual annotation has been difficult to meet the growing demand because of its high cost and many limitations. The traditional model is usually based on the target detection algorithm of manual features, and the detection of human posture features is not accurate. Compared with global image features such as line features, texture features and structure features, local image features have the characteristics of rich quantity in the image, low correlation between features, and will not affect the detection and matching of other features due to the disappearance of some features in the case of occlusion. Referring to the practice of Deep-ID network considering both local and global features, this paper adjusts the traditional neural network, and combines the improved neural network with the human joint model to form a human pose detection method based on graph neural network, and then applies the algorithm to multiperson human pose estimation. The results of several groups of comparative experiments show that the algorithm can better estimate the human posture in sports competition video, and has a good performance in solving multiperson pose estimation in sports game video.

RESUMO

(1) Background: Idiopathic scoliosis occurs in 2 to 4% of children between 10 and 16 years of age. Due to the harmfulness of radiological examination, non-invasive devices, including the 3D ultrasound technology and Scolioscan apparatus, are more and more frequently used for postural diagnostics. The aim of the study was to analyze the parameters of posture in patients with idiopathic scoliosis with the use of 3D ultrasound diagnostics. (2) Methods: The study included 20 girls, aged 10 to 16 years, with double-curve idiopathic scoliosis (the value of primary curve ranged from 25-50°), types I and II according to King-Moe classification. On the basis of X-ray scan, the Cobb angle of primary and secondary curves was assessed, the skeletal maturity was evaluated with the Risser test, and the type of scoliosis was determined. The girls participated in a 3-week rehabilitation program. The examinations were performed before and after therapy. A scoliometer was used for measurements. Each of the participants underwent individual therapy. The three-plane approach to asymmetric exercises was based largely on positions that included primary curve correction with hypercorrection of the secondary curve. (3) Results: After the therapy, values of trunk rotation angles and the angle of scoliotic curvature of secondary curve were significantly lower than before the therapy, except for the value of the primary curve angle. The parameters measured by X-ray were significantly and positively related to the results obtained with the scoliometer and the scolioscan. (4) Conclusions: The application of therapy that takes into account summing parameters may prevent the deterioration of the secondary curve when treating patients with idiopathic scoliosis. The observed correlations between the parameters of the radiological examination, the scoliometer, and the scolioscan prove the possibility of their interchangeable application in the assessment of effects of the therapy. Three-dimensional ultrasound diagnostics may become an alternative to radiological examination in assessing the treatment effects of patients with idiopathic scoliosis.

RESUMO

Industrial workplaces expose workers to a high risk of injuries such as Work-related Musculoskeletal Disorders (WMSDs). Exoskeletons are wearable robotic technologies that can be used to reduce the loads exerted on the body's joints and reduce the occurrence of WMSDs. However, current studies show that the deployment of industrial exoskeletons is still limited, and widespread adoption depends on different factors, including efficacy evaluation metrics, target tasks, and supported body postures. Given that exoskeletons are not yet adopted to their full potential, we propose a review based on these three evaluation dimensions that guides researchers and practitioners in properly evaluating and selecting exoskeletons and using them effectively in workplaces. Specifically, evaluating an exoskeleton needs to incorporate: (1) efficacy evaluation metrics based on both subjective (e.g., user perception) and objective (e.g., physiological measurements from sensors) measures, (2) target tasks (e.g., manual material handling and the use of tools), and (3) the body postures adopted (e.g., squatting and stooping). This framework is meant to guide the implementation and assessment of exoskeletons and provide recommendations addressing potential challenges in the adoption of industrial exoskeletons. The ultimate goal is to use the framework to enhance the acceptance and adoption of exoskeletons and to minimize future WMSDs in industrial workplaces.

RESUMO

Background and Aim: To determine the effect of postural changes on intraocular pressure (IOP) among newly diagnosed patients with primary open-angle glaucoma (POAG). Patients and Methods: This was a cross-sectional observational study of 55 consecutive newly diagnosed patients with POAG attending Glaucoma clinics at a Federal Teaching Hospital in Abakaliki, Ebonyi state, from July to September 2017. Patients IOPs were measured in the sitting position, supine without a pillow, and supine with pillow positions using Perkin's handheld applanation tonometer. All data were analyzed with SPSS version 20.0. Results: A total of 55 subjects were recruited comprising 30 (54.5%) males and 25 (45.5%) females, with a mean age of 50.13 ± 9.97 years and an age range of 30-79 years. The mean intraocular pressure was 27.54 ± 3.98 mmHg in the sitting position, 30.15 ± 4.41 mmHg in the supine with pillow position, and 35.22 ± 4.61 mmHg in the supine without pillow position. The mean difference of mean IOP of sitting compared to supine without the pillow was 7.68 ± 2.08 mmHg (P-value < 0.001, 95% CI: 7.12-8.24); sitting compared to supine with the pillow was 2.61 ± 1.49 mmHg (P-value < 0.001, 95% CI: 3.01-2.21), whereas supine without the pillow compared to supine with the pillow was 5.07 ± 2.24 mmHg (P-value 0.001, 95% CI: 4.47-5.68). Conclusion: IOP was lowest in the sitting position and highest in the supine without pillow position. There was a statistically significant reduction in IOP on the assumption of supine with pillow position compared to supine without pillow position. The use of thick pillows in supine positions (such as during sleep or relaxations) rather than lying supine without pillows may reduce IOP spikes in POAG patients. This may have a positive effect as regards treatment and progression of glaucoma.
