Effects of rTMS to primary motor cortex and cerebellum on balance control in healthy adults.

Both the primary motor cortex (M1) and the cerebellum are crucial for postural stability and deemed as potential targets for non-invasive brain stimulation (NIBS) to enhance balance performance. However, the optimal target remains unknown. The purpose of this study was to compare the role of M1 and the cerebellum in modulating balance performance in young healthy adults using facilitatory 5Hz repetitive transcranial magnetic stimulation (rTMS). Twenty-one healthy young adults (mean age = 27.95 ±1.15 years) received a single session of 5Hz rTMS on M1 and the cerebellum in a cross-over order with a 7-day washout period between the two sessions. Three balance assessments were performed on the Biodex Balance system SD: Limits of Stability (LOS), modified Clinical Test of Sensory Interaction on Balance (mCTSIB), and Balance Error Scoring System (BESS). No significant effect of rTMS was found on the LOS. The effect of rTMS on the mCTSIB was mediated by stimulation target, proprioception, and vision (p = .003, ηp 2 = 0.37). Cerebellar rTMS improved the mCTSIB sway index under eyes closed-foam surface condition (p = .02), whereas M1 rTMS did not result in improvement on the mCTSIB. The effect of rTMS on the BESS was mediated by stimulation target, posture, and proprioception (p = .049, ηp 2 = 0.14). Cerebellar rTMS enhanced reactive balance performance during most sensory deprived conditions.

Sensory Factors Influence Dynamic and Static Bi-Manual Finger Grip Strength in a Real-World Task Context

Individual grip strength provides a functional window into somatosensory processes and their effects on motor behaviour in healthy, impaired, and ageing individuals. Variations in grip strength during hand–tool interaction are therefore exploited in a variety of experimental tasks to study the effects of pathology or ageing-related changes on sensory, motor, and cognitive ability. However, many different factors may influence individual grip strength systematically in a given task context without being explicitly identified and controlled for. Grip strength may vary as a function of the location of the measurement device (sensor) on the fingers/hand, the shape, weight and size of object(s) being gripped, the type of grip investigated (static versus dynamic grip), and the hand (dominant versus non-dominant) used for gripping. This study tests for additional factors such as sight, sound, and interactions with/between any of the other factors in a complex task context. A wearable biosensor system, designed for measuring grip strength variations in operators gripping cylindrical objects bi-manually, was used. Grip force signals were recorded from all sensors of the wearable (glove) system, including three directly task-relevant sensors for bi-manually gripping cylindrical objects with the dominant and non-dominant hands. Five young male participants were tested for the effects of sound, movement, and sight on grip strength. The participants had to pick up two cylindrical objects of identical size and weight, then hold them still (static grip) or move them upwards and downwards (dynamic grip) for ten seconds while listening to soft or hard music, with their eyes open or blindfolded. Significant effects of sensor location, hand, movement, sight, and sound on bi-manual grip strength were found. Stronger grip force signals were produced by task-relevant sensors in the dominant hand when moving the cylindrical handles (dynamic grip) in comparison with the static grip condition, depending, as expected, on whether grip signals were measured from the dominant or the non-dominant hand. Significantly stronger grip strength was produced blindfolded (sight condition), and grips were significantly stronger with exposure to harder music (sound factor). It is concluded that grip strength is significantly influenced by sensory factors and interactions between the other factors tested for, pointing towards the need for identifying and systematically controlling such potential sources of variation in complex study task contexts.

Objective estimation of m-CTSIB balance test scores using wearable sensors and machine learning.

Accurate balance assessment is important in healthcare for identifying and managing conditions affecting stability and coordination. It plays a key role in preventing falls, understanding movement disorders, and designing appropriate therapeutic interventions across various age groups and medical conditions. However, traditional balance assessment methods often suffer from subjectivity, lack of comprehensive balance assessments and remote assessment capabilities, and reliance on specialized equipment and expert analysis. In response to these challenges, our study introduces an innovative approach for estimating scores on the Modified Clinical Test of Sensory Interaction on Balance (m-CTSIB). Utilizing wearable sensors and advanced machine learning algorithms, we offer an objective, accessible, and efficient method for balance assessment. We collected comprehensive movement data from 34 participants under four different sensory conditions using an array of inertial measurement unit (IMU) sensors coupled with a specialized system to evaluate ground truth m-CTSIB balance scores for our analysis. This data was then preprocessed, and an extensive array of features was extracted for analysis. To estimate the m-CTSIB scores, we applied Multiple Linear Regression (MLR), Support Vector Regression (SVR), and XGBOOST algorithms. Our subject-wise Leave-One-Out and 5-Fold cross-validation analysis demonstrated high accuracy and a strong correlation with ground truth balance scores, validating the effectiveness and reliability of our approach. Key insights were gained regarding the significance of specific movements, feature selection, and sensor placement in balance estimation. Notably, the XGBOOST model, utilizing the lumbar sensor data, achieved outstanding results in both methods, with Leave-One-Out cross-validation showing a correlation of 0.96 and a Mean Absolute Error (MAE) of 0.23 and 5-fold cross-validation showing comparable results with a correlation of 0.92 and an MAE of 0.23, confirming the model's consistent performance. This finding underlines the potential of our method to revolutionize balance assessment practices, particularly in settings where traditional methods are impractical or inaccessible.

Correlation of postural stability with pain, disability and quality of life among patients with sacroiliac joint dysfunction- A cross-sectional study

Context-Sacroiliac (SI) joint dysfunction accounts for altered postural stability which can cause a continuously intense pain level and range of disabilities. AimTo investigate the correlation of postural stability with pain, disability & QOL among sufferers of sacroiliac joint dysfunction. SettingThis cross-sectional research was undertaken at Rehabilitation Centre, Jamia Hamdard University. MethodA total of fifty participants were recruited using sample of convenience according to inclusion and exclusion criteria. After obtaining informed consent, three pain provocative tests and one motion palpation test were used to determine sacroiliac joint dysfunction. Humac balance master system (CSMi USB powered, Stoughton, USA), Visual analogue scale (VAS), modified Oswestry Disability Index (ODI) & WHO QOL-BREF (US version) were used to assess postural stability, pain, disability & Quality of life (QOL) respectively. Data analysis was done for correlation by SPSS version 24.0. ResultStrong positive correlations were found between reaction time, VAS (r = 0.791) and modified ODI score (r = 0.576) and weak positive correlations between eyes closed solid surface (ECSS) component of modified clinical test of sensory interaction & balance with VAS (r = 0.333) and with modified ODI score (r = 0.304) and eyes open foam surface (EOFS) component with environmental component of QOL (r = 0.287). There were negative correlations between reaction time, physical health (r = −0.413), psychological health (r = −0.375), social relations (r = −0.305), and environment (r = −0.379) parameters of QOL. ConclusionAccording to the findings of the study, there were positive correlations of reaction time with pain and disability and negative correlations with QOL. Awareness of clinicians regarding the altered postural stability can help in improvising the assessment and treatment protocols for patients of SI dysfunction.

The Feel of Speech: Multisystem and Polymodal Somatosensation in Speech Production.

The oral structures such as the tongue and lips have remarkable somatosensory capacities, but understanding the roles of somatosensation in speech production requires a more comprehensive knowledge of somatosensation in the speech production system in its entirety, including the respiratory, laryngeal, and supralaryngeal subsystems. This review was conducted to summarize the system-wide somatosensory information available for speech production. The search was conducted with PubMed/Medline and Google Scholar for articles published until November 2023. Numerous search terms were used in conducting the review, which covered the topics of psychophysics, basic and clinical behavioral research, neuroanatomy, and neuroscience. The current understanding of speech somatosensation rests primarily on the two pillars of psychophysics and neuroscience. The confluence of polymodal afferent streams supports the development, maintenance, and refinement of speech production. Receptors are both canonical and noncanonical, with the latter occurring especially in the muscles innervated by the facial nerve. Somatosensory representation in the cortex is disproportionately large and provides for sensory interactions. Speech somatosensory function is robust over the lifespan, with possible declines in advanced aging. The understanding of somatosensation in speech disorders is largely disconnected from research and theory on speech production. A speech somatoscape is proposed as the generalized, system-wide sensation of speech production, with implications for speech development, speech motor control, and speech disorders.

The Effects of Concussions on Static Postural Stability

Concussions among the athletic population are extremely common, which could lead to postural instabilities. The purpose of this study was to assess the effect of concussions on postural stability in young healthy adults. The static postural stability of thirty volunteers (age 21.63 ± 2.50 years; height 1.70 ± 0.14 m; weight 75.00 ± 15.58 kg; 17 with a history of concussions) was assessed using a force platform during three tests: baseline stability test, clinical test of sensory interaction and balance test, and unilateral stability test. Postural sway variables during each test were statistically analyzed using an independent t-test between the concussion group (CONC) and no concussion (NO CONC) groups. Two secondary analyses were performed with the CONC group: individuals who had one concussion (ONCE) vs. who had multiple concussions (MULTIPLE) and individuals who had their last concussion in 2023–2018 (RECENT) and in 2017–2011 (OLD). The CONC, MULTIPLE, and RECENT groups demonstrated greater postural sway than the NO CONC, SINGLE, and OLD groups. Concussions cause postural decrements in young healthy adults compared to their counterparts with no history of concussions. The results of the study exhibit that concussions could lead to imbalances, which is decisive in athletes’ performance and injury risk during play.

Characterizing personalized ecologies

AbstractPeople have unique sets of direct sensory interactions with wild species, which change through their days, weeks, seasons, and lifetimes. Despite having important influences on their health and well‐being and their attitudes towards nature, these personalized ecologies remain surprisingly little studied and are poorly understood. However, much can be inferred about personalized ecologies by considering them from first principles (largely macroecological), alongside insights from research into the design and effectiveness of biodiversity monitoring programmes, knowledge of how animals respond to people, and studies of human biology and demography. Here I first review how three major sets of drivers, opportunity, capability and motivation, shape people's personalized ecologies. Second, I then explore the implications of these mechanisms for how more passively and more actively practical improvements can be made in people's personalized ecologies. Particularly in light of the declines in the richness of these ecologies that are being experienced in much of the world (the so‐called ‘extinction of experience’), and the significant consequences, marked improvement in many people's interactions and experiences with nature may be key to the future of biodiversity.

Psychostimulant Medications for Physical Function and Spasticity in Children With Cerebral Palsy: Protocol for a Randomized Controlled Trial.

Cerebral palsy (CP) is a prevalent nonprogressive disorder that leads to impaired movement (ie, spasticity), posture, and balance, which affects functions such as walking and upper extremity tasks. Current medical treatments show efficacy in improving motor performance but have considerable side effects. Emerging off-label use of central nervous system (CNS) medications for improving motor performance has shown promising results in children with CP and other populations. The aim of this study is to describe a protocol for a pilot randomized controlled trial (RCT) to examine the safety, tolerability, and efficacy of methylphenidate (MPH) and modafinil on spasticity and motor performance in children with CP. This will be a protocol study for a pilot, triple-masked, placebo-controlled RCT (a class I trial following the American Academy of Neurology criteria) with blinded patients, outcome assessors, and intervention delivery team. Eligible children should be diagnosed with CP levels I or II based on the Gross Motor Function Classification System and be aged between 7 and 12 years. Thirty-six children with CP will be randomized into 3 groups to receive (1) MPH (2.5 mg of MPH + 100 mg placebo), (2) modafinil (100 mg modafinil + 2.5 mg placebo), or (3) a placebo (2.5 mg placebo + 100 mg placebo), in addition to physical therapy for 12 weeks. Primary outcomes include the Gross Motor Function Measure-66 and the Modified Ashworth Scale. Secondary outcomes include the Timed Up and Go test, 5 Time Sit to Stand test, Modified Clinical Test for Sensory Interaction of Balance, and 10-Meter Walk Test. The protocol has been accepted by Kuwait University (VDR/EC-225) and the Ministry of Health of Kuwait (2022/2157). The inclusion of participants will start in June 2024. The combination of CNS stimulant medications and controlling for rehabilitation has not been studied yet. The findings of this study may determine if using CNS stimulant medications is beneficial for the reduction of spasticity and improvement of physical function in children with spastic CP.

Investigation of the interaction between lactones and ketones in a Cheddar cheese matrix using Feller's additive model, σ-τ plots, U-models, and aroma addition experiments

The objective of this study was to examine the sensory interactions between lactones and ketones in a Cheddar simulation matrix through perceptual interaction analysis. The olfactory thresholds of 6 key lactones had values ranging from 8.32 to 58.88 μg/kg, whereas those of the 4 key ketones ranged from 6.61 to 660.69 μg/kg. Both Feller's additive model and σ-τ plots demonstrated complex interactions in 24 binary mixtures composed of the 6 lactones and 4 ketones, including synergy, addition, and masking effects. Specifically, we found that 6 binary mixtures exhibited aroma synergistic effects using both methods. Moreover, the σ-τ plot showed a synergistic effect of aroma in 3 ternary mixtures. The U-model further confirmed the synergistic effects of the 6 groups of binary systems and 3 groups of ternary systems on aroma at actual cheese concentrations. In an aroma addition experiment, the combination of δ-octalactone and diacetyl in binary mixtures had the most pronounced effect on enhancing milk flavor. In ternary mixtures, 2 combinations, namely δ-octalactone/δ-dodecalactone/diacetyl and γ-dodecalactone/δ-dodecalactone/acetoin, significantly enhanced the milky and sweet aroma properties of cheese, while also enhancing the overall acceptability of the cheese aroma.

Effects of Sensory Input Interactions on Components of Nonlinear Dynamics of Postural Sway in Aging

Postural control involves complex nonlinear dynamics influenced by the interaction and adaptation of different sensory inputs. However, it is not how these inputs interact with one another due to the complex complications associated with aging, particularly concerning the nonlinear dynamics of postural sway. This study aimed to examine how different sensory inputs, surface conditions, and aging factors to influence postural control mechanisms between young and older by investigating the nonlinear dynamics of postural control using the stabilogram diffusion analysis (SDA) and entropy methods. SDA parameters were much greater on foam surfaces than on firm surfaces for both groups in eyes-open and eyes-closed conditions (p ≤ 0.05). For older subjects, there were significant differences in entropy values between firm and foam surfaces (p ≤ 0.05) but no significant difference between eyes conditions (p > 0.05). For both SDA and entropy parameters, surface and age interaction potentially revealed significant differences between young and older subjects (p ≤ 0.05) than eyes and age interaction. The present study provided insight into uncovering the complex relationships between sensory inputs, surface conditions, age, and their potential interaction effects on postural control mechanisms that could mitigate falls and alleviate the fear of falling, particularly in older populations.

Comparison of Effects of Balance Training Exercise and Gaze Stability Exercises on Balance and Postural Control in Elderly With Fall Risk: A Randomized Controlled Trial

Aim To compare the changes in outcomes of balance and postural control after balance training exercise and gaze stability exercise in the elderly population with fall risk. Methods After the screening process, 44 subjects were randomized into three groups: Experimental Group A (Balance training exercises, BTE); Experimental Group B (Gaze stability exercises, GSE), and Control Group C (Fall prevention education only). The outcome measures were center of pressure (COP) range, COP sway, reaction time, proprioception, static balance, Clinical Test for Sensory Interaction in Balance (CTSIB), and Short Falls Efficacy Scale (SFES). The pre and post-data were recorded at baseline and after 8 weeks. The normality of the distribution was assessed using the Shapiro-Wilk test. Demographic data and baseline measures were compared using one-way ANOVA considering group as between factor and mixed model ANOVA was used to find out the group effect and time effect and time × group interaction effect. Statistical significance was indicated if p ≤ 0.05. Results GSE had significant changes only in CTSIB 4 whereas BTE had significant changes in CTSIB 4, 5, and 6. COP range showed a significant time effect in the front direction (p = 0.02). For proprioception, there was a significant time effect in the left (p = 0.018) and right direction (p = 0.005), whereas changes in front and back directions were found to be insignificant. SFES showed a significant time effect (p < 0.001), group effect (p = 0.21), and time × group interaction effect (p < 0.001). Conclusion Balance training exercises may be a more effective form of intervention to improve balance and postural control in the elderly population.

Network architecture of intrinsic connectivity in a mammalian spinal cord (the central nervous system’s caudal sector)

The vertebrate spinal cord (SP) is the long, thin extension of the brain forming the central nervous system's caudal sector. Functionally, the SP directly mediates motor and somatic sensory interactions with most parts of the body except the face, and it is the preferred model for analyzing relatively simple reflex behaviors. Here, we analyze the organization of axonal connections between the 50 gray matter regions forming the bilaterally symmetric rat SP. The assembled dataset suggests that there are about 385 of a possible 2,450 connections between the 50 regions for a connection density of 15.7%. Multiresolution consensus cluster analysis reveals a hierarchy of structure-function subsystems in this neural network, with 4 subsystems at the top level and 12 at the bottom-level. The top-level subsystems include a) a bilateral subsystem related most clearly to somatic and autonomic motor functions and centered in the ventral horn and intermediate zone; b) a bilateral subsystem associated with general somatosensory functions and centered in the base, neck, and head of the dorsal horn; and c) a pair of unilateral, bilaterally symmetric subsystems associated with nociceptive information processing and occupying the apex of the dorsal horn. The intrinsic SP network displayed no hubs, rich club, or small-world attributes, which are common measures of global functionality. Advantages and limitations of our methodology are discussed in some detail. The present work is part of a comprehensive project to assemble and analyze the neurome of a mammalian nervous system and its interactions with the body.

3D Multimodal Sensing and Feedback Finger Case for Immersive Dual‐Way Interaction

AbstractWith the rapid development of virtual reality (VR) technology, artificial intelligence , and the Internet of Things , a new era of immersive interaction with the digital world has emerged. In this context, a novel soft finger case with 3D multi‐modal sensing and feedback functions (3D‐SFC) is presented. The device leverages multiple material properties to create a modulated fingertip haptic feedback for the perception of orientation and force, triboelectric nanogenerator (TENG) sensing with dynamic and static responses and control of movement, and thermal feedback based on resistive heating of TENG electrodes. The integrated TENG tactile sensing unit in the device is capable of recognizing the texture of an object's surface, providing users with a more natural and intuitive way of interacting with digital objects. The spatial consistency of multi‐modal sensing and feedback enhances human‐machine interaction in various fields such as healthcare, manufacturing and assembly, and gaming, etc. The proposed device represents a new intelligent sensing solution for achieving cross‐space sensory interaction, opening up new possibilities for the future of VR and digital interaction.

Effects of elastic taping on kyphosis and body balance in the elderly: a randomized crossover study

Kyphosis produces abnormal posture and reduced body balance in the elderly. Elastic tape may be useful at improving kyphotic posture and body balance. This study aims to evaluate the effects of elastic taping on kyphosis and body balance in the elderly. Ten elderly participants with degenerative kyphotic posture were recruited and randomly assigned to two groups (back taped with stretched elastic tape for 15 min and back taped with non-stretched elastic tape for 15 min). After a 1-h washout period, the groups were swapped over to receive the other intervention. The outcomes measured after each taping technique were Cobb’s angle measurement by inclinometer, perceived pain, and balance measurements by single leg stance test, time up and go test, center of gravity alignment (COG) and modified clinical test of sensory interaction on balance test (mCTSIB). There was a significant reduction in kyphotic angle and back pain in both the stretched and non-stretched taping groups (p < 0.05). We also found both taping techniques significantly reduced sway velocity on a foam surface with eyes closed and open (p < 0.05). However, there was no significant difference between taping groups for kyphotic angle, pain reduction or balance. The application of 15 min of stretched and non-stretched elastic tape in the elderly reduced kyphotic angle, back pain, and sway velocity while standing on foam surface in the mCTSIB test. If these changes persist over the long term (days and weeks) taping may be a useful intervention for elderly patients with kyphosis.

Physiotherapy Intervention for Binder’s Syndrome with Holoprosencephaly: A Unique Case Report

Maxillonasal dysplasia, known as Binder’s syndrome, is a rare congenital deformity characterised by distinctive facial features, including a malformed midface and nose, as well as abnormal positions of the nasal bones. In addition, maxillary hypoplasia, or a shorter upper jaw, and nasal abnormalities may manifest as a flattened nose. Many cases of this condition are associated with other malocclusions, and those affected can be easily identified. Individuals with Binder’s syndrome typically present with an undeveloped upper jaw, a projecting lower jaw, a smaller nose, a flat nasal bridge, and midfacial hypoplasia. This is the first case report describing a physiotherapy method for maxillonasal dysplasia. Hereby, the authors present a case report of a six-month-old male child with Binder’s syndrome who exhibited delayed developmental milestones and physical anomalies. The child’s mother had a complicated pregnancy, culminating in an emergency caesarean section due to preterm premature rupture of membranes. The infant, born with Binder’s syndrome and a cleft palate, displayed poor head control, an inability to roll, and reluctance to engage in sensory interactions. Examination revealed bilateral cortical thumbs, hip joint abnormalities, and heightened sensitivity to touch. Magnetic Resonance Imaging (MRI) findings indicated semilobar Holoprosencephaly (HPE) and dysgenesis of the corpus callosum. Physiotherapeutic interventions focused on parent education and home exercise programs targeting developmental milestones. Over the course of two months, the infant showed significant progress in head control and rolling. Furthermore, after four months of training, the child gained sitting control. The present case underscores the importance of early intervention and parental involvement in optimising outcomes for children with Binder’s syndrome.

Nintendo Ring Fit Adventure improves balance ability in sedentary young adults

IntroductionExercising with a game console is a novel type of exercise. One game that is currently popular is Nintendo Ring Fit Adventure, but its impact on balancing ability in young adults who are sedentary has yet to be investigated. This study aimed to investigate the effects of Nintendo Ring Fit Adventure exercise on balance ability in young adults with sedentary lifestyles.MethodsThirty participants were randomly divided into two groups: the Nintendo and control groups. The experimental group completed a workout routine using the Nintendo Ring Fit for 30 minutes per day, three times per week for four weeks, while the control group received no intervention. Participants’ balance abilities were evaluated pre- and post-intervention by the single leg stance test, Modified Clinical Test of Sensory Interaction in Balance (MCTSIB), and limit of stability. A one-way ANCOVA with the pre-intervention value as a covariate was used to compare groups.ResultsComparisons between groups after the intervention revealed a significant decrease in MCTSIB sway for the firm surface with eyes open condition (p = 0.043) and a significant increase in endpoint excursion in the backward direction (p = 0.038). The other variables did not show statistically significant differences between groups.ConclusionsExercise with Nintendo Ring Fit improved the participants’ ability to balance in certain dimensions. Nintendo Ring Fit may increase the balance ability of young adults with sedentary behaviour.

Virtual Reality-based Meta-Cosmic Perspective on Curriculum Integration Innovations in Art and Technology Programs

Abstract At the end of the 20th century, the development of science and technology has made remarkable achievements, and some artists have begun to try to integrate science and technology into art creation. In this paper, based on DEM art space analysis, Unity technology is added to build a three-dimensional scene for teaching art and technology professional courses. At the same time, HoloLens2-based sensory interaction technology is introduced to enhance the integration of art and technology in the virtual classroom. Based on this basis, a teaching framework for VR art and technology fusion courses centered on students’ learning and interaction experience is designed and applied to actual teaching. In the sample correlation analysis, the experience of the relevant courses in the early stage had a significant impact on both the shadow students’ artistic self-perception (t=0.7854, p&lt;0.01) and their learning behaviors in the later stage (t=0.6452, p&lt;0.01). After the integration of art and technology teaching, the student’s interest in art learning and technology learning were both enhanced, with the mean values of 0.07398 and 0.0.20255, respectively, and the integration of art and technology professional course curriculum based on virtual reality technology effectively improved the students’ learning interest.
