RESUMO

Dynamic balance is particularly important for the maintenance, transformation, and restabilization of various postures of the human body. Combined with the characteristics of unbalanced sports events, although there is no physical contact in sports events, it has intense antagonism due to the constant change of body movement. Athletes need to have the ability of fast movement and continuous high-intensity multibeat confrontation. They need to adjust their body posture any time according to the situation, constantly move their body from one side to the other side in fast movement, and constantly change between being imbalanced and being stable to keep the center of gravity stable and adjust their body posture. Combining with the characteristics of unbalanced sports, this paper is aimed at the problem that young athletes have poor dynamic balance ability and cannot maintain the stability of their body's center of gravity in the process of fast multidirectional movement and braking. The supporting leg needs ankle dorsiflexion, knee flexion, and hip flexion during SEBT testing. Therefore, the lower limb needs sufficient range of motion, strength, proprioception, and neuromuscular control ability to achieve the optimal test results. A randomized controlled experiment was used to test whether there were significant differences in the test indicators between the experimental group and the control group before and after the experiment by using a paired test. The test indicators between the experimental group and the control group before and after the intervention were tested by independent sample test to explore the influence of core balance training on the dynamic balance ability of teenagers in unbalanced sports. Through analysis, it is proved that strengthening balance exercise can significantly improve the functional movements and physical fitness of adolescents, which is of great significance to the development of basic flexibility and stability of joints and the strengthening of weak chain muscles.

RESUMO

The human being dynamically and highly controls the head-trunk with redundant mechanical structures to maintain a stable upright standing position that is inherently unstable. The posture control strategies are also affected by the differences in the conditions of sensory inputs. However, it is unclear how the head-trunk segmental properties are altered to respond to situations that require appropriate changes in standing posture control strategies. We used a data-driven approach to conduct a multipoint measurement of head-trunk sway control in a quiet standing position with differences in the conditions of sensory inputs. Healthy young subjects with 22 accelerometers attached to their backs were evaluated for head-trunk vibration during quiet standing under two conditions: one with open eyes and one with closed eyes. The synchronization of the acceleration and the instantaneous phase was then calculated. The results showed that the synchronization of acceleration and instantaneous phase varied depending on the visual condition, and there were some continuous coherent patterns in each condition. Findings were that the structural redundancy of the head-trunk, which is multi-segmental and has a high mass ratio in the whole body, must be adjusted adaptively according to the conditions to stabilize upright standing in human-specific bipeds.

RESUMO

ABSTRACT: Soriano, MA, Jiménez-Ormeño, E, Amaro-Gahete, FJ, Haff, GG, and Comfort, P. How does lower-body and upper-body strength relate to maximum split jerk performance? J Strength Cond Res 36(8): 2102-2107, 2022-The aims of this study were to (I) determine the relationships between the maximum dynamic strength of the upper and lower body, measured by overhead press and back squat 1 repetition maximum (1RM) performances, and the split jerk (SJ) performance in trained weightlifters and (II) explore the magnitude of these relationships for men and women to establish sex-specific prediction equations. Twenty men (age: 28.9 ± 6.6 years; height: 1.8 ± 0.1 m; body mass [BM]: 82.5 ± 10.2 kg; weightlifting training experience: 4.2 ± 2.4 years) and 13 women (age: 27.7 ± 4.4 years; height: 1.7 ± 0.1 m; BM: 61.8 ± 5.2 kg; weightlifting training experience: 2.7 ± 1.7 years) competitive weightlifters participated. The 1RM performances of the overhead press, back squat, and SJ were assessed for all subjects. A very strong correlation exists between the back squat and overhead press, with maximum SJ performance for all subjects (r = 0.97; p < 0.001). Similarly, very strong correlations were found for men (r = 0.90, p < 0.001) and women (r = 0.90, p = 0.0002), separately. The coefficient of determination indicates that the prediction equation for the maximum SJ performance is quite accurate (R2 = 0.94) for all subjects and men (R2 = 0.83) and women (R2 = 0.81), separately. These results provide evidence that the maximum strength of the upper and lower body are major contributors to SJ performance. In addition, SJ performance can accurately be predicted from the back squat and overhead press performances.

RESUMO

Purpose: Head tilt associated with infantile nystagmus syndrome (INS) can be corrected by (a) operating the oblique muscles, (b) horizontally transposing the vertical rectus muscles, or (c) vertically transposing the horizontal rectus muscles. We report three cases of INS with head tilt corrected by vertically transposing the horizontal rectus muscles in both the eyes. Methods: Three cases of head tilt with INS from an institutional practice operated by a single surgeon were retrospectively reviewed and analyzed. The intervention included full tendon width transposition (upward or downward) of all four horizontal rectus muscles to induce cyclotorsion in the direction of head tilt. The primary outcome measure was the correction of head tilt in the primary position. Results: Three patients (boys) of ages ranging from 4 to 7 years with a pre-operative head tilt of 30° were operated upon. Although one patient's oblique muscles had been operated on to correct head tilt, another patient had an unmasked face turn after the surgery, which was corrected with a modified Anderson's procedure. Post-operatively, all patients had a reduction of head tilt to a range of 0-10°. Conclusion: Vertical transposition of horizontal rectus muscles is a simple surgical option to correct head tilt in INS. However, the results may vary based on individual cases.

RESUMO

We developed a method to estimate a biomechanically feasible precision grip posture of the human hand for a given object based on a minimization of the muscle effort. The hand musculoskeletal model was constructed as a chain of 21 rigid links with 37 intrinsic and extrinsic muscles. To grasp an object, the static force and moment equilibrium condition of the object, force balance between the muscle and fingertip forces, and static frictional conditions must be satisfied. We calculated the hand posture, fingertip forces, and muscle activation signals for a given object to minimize the square sum of the muscle activations while satisfying the above kinetic constraints using an evolutionary optimization technique. To evaluate the estimated hand posture and fingertip forces, a wireless fingertip force-sensing device with two six-axis load cells was developed. When grasping the object, the fingertip forces and hand posture were experimentally measured to compare with the corresponding estimated values. The estimated hand postures and fingertip forces were in reasonable agreement to the corresponding measured data, indicating that the proposed hand posture estimation method based on the minimization of muscle effort is effective for the virtual ergonomic assessment of a handheld product.

RESUMO

The primary prevention program of the Hungarian Spine Society was launched in 1995 with two goals: 1. to achieve that all school-children take part regularly in effective posture correcting exercises as part of physical education; and 2. to achieve daily physical education for all school-children. With appropriate governmental legislation and parliamentary decision both goals were integrated into the National Public Health Program in 2001 and 2003 and later in the national educational laws and documents. From 2011 and 2012 holistic health promotion in schools with the goal to reach all children became also prescription for all schools in Hungary. Public health institutions and actors still have to do much: they have to give continuous professional help to the physical education teachers in their posture correcting work and to all teachers in their daily health promoting tasks. The article presents the details of the special posture correcting exercises, their distribution and prospective controlled studies, their place in the national education, the present situation and the further tasks. The article is supplemented by a short report about daily physical education and holistic health promotion in schools: how the prescription was achieved, the essence and the follow up of it, and what are the tasks for the helping public health actors.

RESUMO

Parkinson's disease (PD) is a progressive neurological disease characterized by muscle stiffness, tremor, slowness of movement, and difficulties with posture and walking. Muscle and joint pain are frequent non-motor symptoms of PD. Pain associated with PD is mainly caused by a combination of truncal dystonia, stooped posture, and muscle rigidity. However, PD deformities were rarely discussed in the literature. A 68-year-old Asian female with PD treated with Levodopa for six years complained of progressive neck pain, contractures, and subluxation of both hands in the last two years. A positron emission tomography (PET) scan revealed decreased rostrocaudal gradient uptake in both posterior putamen. After 9 months of multimodal chiropractic rehabilitation, the patient had significant improvement in symptoms, including pain resolution as per the numeric rating scale and physical and mental improvement as per the PD questionnaire. Radiographic measurement showed significantly improved postural alignment and stability. Measurement of joint motion and angles showed an improvement in hand deformity. Although PD is a neurodegenerative disease that is not curable, multimodal rehabilitation may improve neurological and musculoskeletal functions by inducing proprioceptive balance, motor strength, and joint movement. The current study may illustrate multimodal rehabilitation addressing orthopedic deformity associated with symptoms in a PD patient.

RESUMO

BACKGROUND: Accumulating evidence indicates that abnormal foot posture are risk factors for knee osteoarthritis (OA). However, the relationship between foot posture and tibiofemoral contact force (CF) during habitual weight-bearing activities remains unclear. This study aimed to determine the association between tibiofemoral CF and foot posture while walking. METHODS: In total, 18 patients with knee OA and 18 healthy individuals participated in this cross-sectional study. Foot parameters were evaluated by Foot Posture Index (FPI), Staheli Arch Index (SAI), hallux valgus angle, calcaneus inverted angle relative to the floor as a static rearfoot posture, navicular height, and toe grip strength. In addition, all participants underwent kinetic and kinematic measurements during a self-selected speed gait. The measurement device used was the three-dimensional motion analysis system with a sampling rate of 120 Hz. The musculoskeletal model, which has 92 Hill-type muscle-tendon units with 23 degrees of freedom, was used to calculate tibiofemoral CF. Partial correlations was used to investigate the association between foot parameters and total, medial, and lateral tibiofemoral CF of the first and second peaks while controlling for gait speed. RESULTS: A significant negative correlation was observed between Walking SAI and first peak medial tibiofemoral CF in control participants (r = -0.505, p = 0.039). SAI was also significantly positively correlated with first peak medial tibiofemoral CF in patients with knee OA (r = 0.482, p = 0.042). CONCLUSIONS: Our findings revealed a correlation between the medial first peak tibiofemoral CF and the SAI. This study indicates that people with knee OA and flatfoot have excessive first medial tibiofemoral CF during walking.

RESUMO

The purpose of this study was to solve the problem of the influence of body posture and different exercise intensity on athletes' limb injuries, to meet the needs of understanding athletes' injuries, and to make up for the lack of investigations on athletes' limb injuries; this also increases the chances of an athlete avoiding injury. Severe acute sports injuries of high-level gymnasts endanger the personal safety of athletes. Many movements in gymnastics are done in the air much higher than the ground, and there is no fulcrum when the athlete does the movements; this just can only maintain balance and change your body posture through your own feelings, a slight error can easily cause your head or upper body to fall down, and the fragile spine cannot withstand the strong impact of the ground, resulting in high vertebral fractures, high paraplegia, and even death. Therefore, through a survey of 126 rhythmic gymnasts who participated in the 2011 "China Art Sports Cup" China Rhythmic Gymnastics Championship, a total of 172 injuries were found in 136 gymnasts, and the injury risk analysis was carried out from the main characteristics of the injuries.

RESUMO

The application of sports game video analysis in athlete training and competition analysis feedback has attracted extensive attention, but the traditional sports human body posture estimation method has a large error between the athlete's human body posture estimation results and the actual results in the complex environment and the athlete's body parts are blocked. Therefore, this study proposes a convolutional neural network for athlete pose estimation in sports game video. Based on the improved model, multiscale model, and large perception model, a superimposed hourglass network is constructed, and the gradient disappearance problem of the convolutional neural network is solved using intermediate supervision. The experimental results show that the athlete pose estimation model based on the convolutional neural network can improve the accuracy of athlete pose estimation and reduce the negative impact of occlusion environment on athlete pose estimation to a certain extent. In addition, compared with other athletes' standing posture estimation methods, the model has competitive advantages and high accuracy under widely used standard conditions.

RESUMO

Occupational logging activities expose workers to a wide range of risk factors, such as lifting heavy loads, prolonged, awkward positioning of the lower back, repetitive movements, and insufficient work pauses. Body posture has an important impact on the level of physiological load. The present study involved a group of 40 loggers in the province of Enna (Sicily, Italy) with the aim of defining the impact of logging activities on the workers' physiological strain during the three primary work tasks of felling, delimbing, and bucking. The Zephyr Bioharness measurement system was used to record trunk posture and heart rate data during work tasks. The NASA TLX questionnaire was used to explore workers' effort perception of the work tasks. Based on our results, the most demanding work task was tree felling, which requires a higher level of cardiac cost and longer periods spent in awkward trunk postures. The perceived physiological workload was consistently underestimated, especially by the more experienced loggers. Lastly, as the weight of the chainsaw increased, the cardiac load increased.

RESUMO

Sit-to-stand and stand-to-sit transfers are fundamental daily motions that enable all other types of ambulation and gait. However, the ability to perform these motions can be severely impaired by different factors, such as the occurrence of a stroke, limiting the ability to engage in other daily activities. This study presents the recording and analysis of a comprehensive database of full body biomechanics and force data captured during sit-to-stand-to-sit movements in subjects who have and have not experienced stroke. These data were then used in conjunction with simple machine learning algorithms to predict vertical motion trajectories that could be further employed for the control of an assistive robot. A total of 30 people (including 6 with stroke) each performed 20 sit-to-stand-to-sit actions at two different seat heights, from which average trajectories were created. Weighted k-nearest neighbours and linear regression models were then used on two different sets of key participant parameters (height and weight, and BMI and age), to produce a predicted trajectory. Resulting trajectories matched the true ones for non-stroke subjects with an average R2 score of 0.864±0.134 using k = 3 and 100% seat height when using height and weight parameters. Even among a small sample of stroke patients, balance and motion trends were noticed along with a large within-class variation, showing that larger scale trials need to be run to obtain significant results. The full dataset of sit-to-stand-to-sit actions for each user is made publicly available for further research.

RESUMO

Determination of spine posture is of great interest for the effective prevention, evaluation, treatment and evolution monitoring of spinal disorders. Limitations of traditional imaging systems, including cost, radiation exposure (for X-ray based systems), projection volume issues and subject positioning requirements, etc., make non-invasive motion assessment tools effective alternatives for clinical and non-clinical use. In this work, a procedure was developed to obtain a subject-specific multibody model of the spine using either inertial or optical sensors and, based on this multibody model, to estimate the locations and orientations of the 17 vertebrae constituting the thoracolumbar spine. The number and calibration of the sensors, angular offsets, scaling difficulties and gender differences were addressed to achieve an accurate 3D-representation of the spine. The approach was validated by comparing the estimated positions of the sensors on 14 healthy subjects with those provided by an optical motion capture system. A mean position error of lower than 12 mm was obtained, thus showing that the proposed method can offer an effective non-invasive tool for the assessment of spine posture.

RESUMO

The motion capture method using sparse inertial sensors is an approach for solving the occlusion and economic problems in vision-based methods, which is suitable for virtual reality applications and works in complex environments. However, VR applications need to track the location of the user in real-world space, which is hard to obtain using only inertial sensors. In this paper, we present Fusion Poser, which combines the deep learning-based pose estimation and location tracking method with six inertial measurement units and a head tracking sensor that provides head-mounted displays. To estimate human poses, we propose a bidirectional recurrent neural network with a convolutional long short-term memory layer that achieves higher accuracy and stability by preserving spatio-temporal properties. To locate a user with real-world coordinates, our method integrates the results of an estimated joint pose with the pose of the tracker. To train the model, we gathered public motion capture datasets of synthesized IMU measurement data, as well as creating a real-world dataset. In the evaluation, our method showed higher accuracy and a more robust estimation performance, especially when the user adopted lower poses, such as a squat or a bow.

RESUMO

COVID-19 has affected daily life in unprecedented ways, with dramatic changes in mental health, sleep time and level of physical activity. These changes have been especially relevant in the elderly population, with important health-related consequences. In this work, two different sensor technologies were used to quantify the energy expenditure of ageing adults. To this end, a technological platform based on Raspberry Pi 4, as an elaboration unit, was designed and implemented. It integrates an ambient sensor node, a wearable sensor node and a coordinator node that uses the information provided by the two sensor technologies in a combined manner. Ambient and wearable sensors are used for the real-time recognition of four human postures (standing, sitting, bending and lying down), walking activity and for energy expenditure quantification. An important first aim of this work was to realize a platform with a high level of user acceptability. In fact, through the use of two unobtrusive sensors and a low-cost processing unit, the solution is easily accessible and usable in the domestic environment; moreover, it is versatile since it can be used by end-users who accept being monitored by a specific sensor. Another added value of the platform is the ability to abstract from sensing technologies, as the use of human posture and walking activity for energy expenditure quantification enables the integration of a wide set of devices, provided that they can reproduce the same set of features. The obtained results showed the ability of the proposed platform to automatically quantify energy expenditure, both with each sensing technology and with the combined version. Specifically, for posture and walking activity classification, an average accuracy of 93.8% and 93.3% was obtained, respectively, with the wearable and ambient sensor, whereas an improvement of approximately 4% was reached using data fusion. Consequently, the estimated energy expenditure quantification always had a relative error of less than 3.2% for each end-user involved in the experimentation stage, classifying the high level information (postures and walking activities) with the combined version of the platform, justifying the proposed overall architecture from a hardware and software point of view.

RESUMO

Balance and posture are two topics that have been extensively studied, although with some conflicting findings. Therefore, the aim of this work is to analyze the relationship between the postural angles of the spine in the sagittal plane and the stable static balance. A cross-sectional study was conducted with children and adolescents from schools in northern Portugal in 2019. An online questionnaire was used to characterize the sample and analyze back pain. Spinal postural angle assessment (pelvic, lumbar, and thoracic) was performed using the Spinal Mouse®, while stabilometry assessment was performed using Namrol® Podoprint®. Statistical significance was set as α = 0.05. The results showed that girls have better balance variables. There is a weak correlation between the anthropometric variables with stabilometry variables and the postural angles. This correlation is mostly negative, except for the thoracic spine with anthropometric variables and the lumbar spine with BMI. The results showed that postural angles of the spine are poor predictors of the stabilometric variables. Concerning back pain, increasing the postural angle of the thoracic spine increases the odds ratio of manifestation of back pain by 3%.

RESUMO

OBJECTIVE: The aim of this study was to investigate whether the treatment of the dental malocclusions can affect the postural attitude in children. STUDY DESIGN: Sixty patients aged 9-12 years in mixed dentition were enrolled. The patients underwent an orthodontic evaluation for dental malocclusion and a postural examination by means of a vertical laser line (VLL) and a stabilometric-baropodometric platform. The children were treated with a functional appliance according to the type of malocclusion for two years. The position of the head and of the atlanto-occipital joint (C0-C1) respects to the VLL, the typologies of podalic support and the distribution of the body weight on the feet were evaluated before and after the orthodontic treatment. RESULTS: A significant correction of the position of the head, with a physiological extension of C0-C1, a significant improvement of the typology of podalic support and a homogeneous distribution of the body weight on the feet were observed after the treatment of the malocclusions. Conclusion; From our results, the treatment of dental malocclusion can contribute to ameliorate the postural attitude in children.

RESUMO

INTRODUCTION: This study was aimed to estimate the effect of one-year persistence of COVID-19 anti-pandemic measures on the posture and spine in children of younger school age in Slovakia. MATERIAL AND METHODS: A total of 135 children aged between 6 and 9 years participated in this study. The examination of posture and spine was carried out in 4 schools in 4 different districts in Slovakia. The posture was evaluated in February 2020, before anti-pandemic restrictions and in period from May 2021, after one year of anti-pandemic restrictions. Modified methodology according to Napoleon Wolanski was used to evaluate the posture. RESULTS: For the entire study group, the mean posture disorder level score before anti-pandemic restrictions was 5.667 (±1.75) and it rose to 7.844 (±0.64). Prevalence of posture disorders rose from 71.11 % to 91.3 % in the study group. The most affected segments were lumbar spine and pelvis, followed by deformities of the thoracis spinae. The mean pathology level score for entire group in these segments rose as followed: in the lumbar spine from 0.6 (±0.61) to 1.022 (±0.75); in the pelvis from 0.444 (±0.54) to 0.772 (±0.73) and in the thoracis spine from 0.378 (±0.53) to 0.578 (±0.61). CONCLUSION: Study confirmed a worsening of the posture and spine in school children after a one year of strict anti-pandemic measures. As postural changes increased by 20 % during the year, it seems necessary to implement appropriate preventives programs for children, which could have the potential to improve their postural state (Tab. 2, Fig. 1, Ref. 37).

RESUMO

OBJECTIVE: The purpose of this study was to determine the accuracy and intrarater reliability of a palpatory protocol based on a combination of 3 palpatory methods to identify both the C7 spinous process (C7 SP) and the factors that affect the errors and inaccuracy of palpation. METHODS: Twenty-five women between the ages of 18 and 60 years were submitted to a palpation protocol of the C7 SP, and a radiopaque marker was fixed on the skin at the possible location of the vertebrae. A radiograph and a photograph of the cervical spine were obtained in the same posture by a first rater. A second rater performed the same palpation protocol and took a second photograph. The accuracy and measurement error of the palpation protocol of C7 SP were assessed through radiographic images. The inter-rater reliability was estimated by the interclass correlation coefficient and assessed using photographs of each rater. The Pearson's correlation coefficients (r), the Fisher exact test, and the χ2 test were used to identify the factors associated with the error and inaccuracy of palpation. RESULTS: Accuracy of the C7 palpation was 76% with excellent reliability (interclass correlation coefficient = 0.99). There was a moderate correlation between weight and the measurement of palpation error (r = -0.6; P = .003). One hundred percent of inaccuracy palpation was related to the increased soft-tissue thickness (P = .005) in the cervical region. CONCLUSION: The palpation protocol described in this study was accurate and presented excellent reliability in identifying the C7 SP. Increased weight and dorsocervical fat pad were associated to error and palpation inaccuracy, respectively.

RESUMO

OBJECTIVE: The purpose of this study was to investigate differences between individuals with various forward head posture (FHP) severities with and without postural neck pain using craniovertebral angle and forward shoulder angle. METHOD: Ninety participants age 20 to 50 years were categorized into the following 4 groups based on observational method and presence or absence of postural neck pain: (1) slight FHP group without pain, (2) slight FHP group with pain, (3) moderate-to-severe FHP group without pain, and (4) moderate-to-severe FHP group with pain. A digital imaging technique was used to measure the craniovertebral angle and forward shoulder angle in a standing position. RESULTS: A 1-way analysis of variance test showed a significant difference for craniovertebral angle in the 4 groups (F = 22.04, P < .001). Tukey's test showed the difference in this variable was significant between slight FHP groups (with or without pain) and moderate-to-severe FHP groups (with or without pain) (P < .001). Although overall F indicated a significant difference (F = 4.11, P < .009) of the forward shoulder angle in 4 groups, Tukey's test revealed this was only significantly different in 2 groups: slight FHP with pain and moderate-to-severe FHP with pain (P = .005). CONCLUSION: The craniovertebral angle in the 2 groups of moderate-to-severe FHP was significantly smaller than that in the 2 groups of slight FHP. However, the forward shoulder angle in the group of moderate-to-severe FHP with pain was only significantly smaller than that in slight FHP with pain. The results showed that including pain as a factor of categorization did not lead to a significant difference between various groups regarding craniovertebral angle and forward shoulder angle.
