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.

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.

Insufficiencies in sensory systems reweighting is associated with walking impairment severity in chronic stroke: an observational cohort study.

Walking and balance impairment are common sequelae of stroke and significantly impact functional independence, morbidity, and mortality. Adequate postural stability is needed for walking, which requires sufficient integration of sensory information between the visual, somatosensory, and vestibular centers. "Sensory reweighting" describes the normal physiologic response needed to maintain postural stability in the absence of sufficient visual or somatosensory information and is believed to play a critical role in preserving postural stability after stroke. However, the extent to which sensory reweighting successfully maintains postural stability in the chronic stages of stroke and its potential impact on walking function remains understudied. In this cross-sectional study, fifty-eight community-dwelling ambulatory chronic stroke survivors underwent baseline postural stability testing during quiet stance using the modified Clinical test of Sensory Interaction in Balance (mCTSIB) and assessment of spatiotemporal gait parameters. Seventy-six percent (45/58) of participants showed sufficient sensory reweighting with visual and somatosensory deprivation for maintaining postural stability, albeit with greater postural sway velocity indices than normative data. In contrast, survivors with insufficient reweighting demonstrated markedly slower overground walking speeds, greater spatiotemporal asymmetry, and limited acceleration potential. Adequate sensory system reweighting is essential for chronic stroke survivors' postural stability and walking independence. Greater emphasis should be placed on rehabilitation strategies incorporating multisensory system integration testing and strengthening as part of walking rehabilitation protocols. Given its potential impact on outcomes, walking rehabilitation trials may benefit from incorporating formal postural stability testing in design and group stratification.

Testing the validity and reliability of a new android application-based accelerometer balance assessment tool for community-dwelling older adults

BackgroundPostural instability is a risk factor for falls in older adults. It is possible to detect postural stability using an integrated accelerometer (ACC) sensor in a smartphone. Therefore, a novel ACC-based smartphone application running on the Android operating system called BalanceLab was created and tested. PurposeThis study aimed to determine the validity and reliability of a novel ACC-based Android smartphone application for assessing balance in older adults. MethodsUsing BalanceLab, 20 older adults completed three balance assessments: the Modified Clinical Test of Sensory Interaction in Balance (MCTSIB), a single-leg stance test (SLST), and a limit of stability test (LOS). The validity of this mobile application was investigated using a three-dimensional (3D) motion analysis system and the Fullerton Advanced Balance (FAB) scale. The test-retest reliability of this mobile application was determined on two separate occasions within one day, at least two hours apart. ResultsThe two static balance assessments (the MCTSIB and SLST) demonstrated moderate to excellent correlation with the 3D motion analysis system (r = 0.70–0.91) and the FAB scale (r = 0.67–0.80). However, the majority of the dynamic balance tests (the LOS tests) did not demonstrate any correlation with the 3D motion analysis system or the FAB scale. This novel ACC-based application demonstrated good to excellent test-retest reliability (ICC = 0.76–0.91). ConclusionA static, but not dynamic, balance assessment tool that uses a novel ACC-based application for Android can be used to measure balance in older adults. This application has moderate to excellent validity and test-retest reliability.

The Effect of Vestibular Rehabilitation on Balance and Quality of Life in Patients with Bilateral Vestibular Hypofunction.

This study aims to investigate the effectiveness of vestibular rehabilitation on balance, dynamic visual acuity, and quality of life in patients with bilateral vestibular hypofunction (BVH). 20 patients diagnosed by videonystagmography were included in the study. Balance tests, Visual Analogue Scale (VAS), testing of Dynamic Visual Acuity (DVA), Dizziness Handicap Inventory (DHI), Computer-modified Clinical Test of Sensory Interaction in Balance (m-CTSIB), and Limits of Stability Test were applied before and 3 and 6months after the treatment. Physiotherapy sessions were given at two-week intervals. According to the development of the patients, they were asked to perform a home exercise program with 10 repetitions 3 times a day. After 6months of vestibular rehabilitation, improvements in balance and quality of life parameters were observed in the patients. VAS, DVA, DHI, all static balance parameters except Romberg, Semi-tandem eyes open were significant (p < 0.005). In computerized M-CTSIB, while no significant results were obtained on the hard surface with the eyes open (p = 0.126), statistically significant improvement was observed on the hard surface with the eyes closed and on a foam surface with eyes open and close. LOS results showed significant improvement in velocity, reaching the endpoint, and maximal deviation in all directions except the right posterior. While significant results were found in the right, posterior, left anterior, and left posterior directions in the reaction time section, there was no statistical significance in any of the direct control sections (p < 0.005). Trial registration number:NCT05231109, Date of registration:27/01/2022 (Retrospectively registered).

Are there placebo or nocebo effects in balancing performance?

Placebo and nocebo effects could influence the perceived, actual, or both postural stabilities. Therefore, this experiment examined whether postural stability is susceptible to placebo and nocebo effects. Driven by expectations, these cognitions could influence the motor stability of people in physical rehabilitation and those with motion instability. We randomly assigned 78 participants to a placebo, nocebo, or control group. Then, we applied a sham sports cream with positive, negative, or neutral instructions about its impact on balance. Next, we tested postural stability with a modified version of the Modified Clinical Test of Sensory Interaction in Balance, including standard, proprioceptive, visual, and vestibular tests before and after the intervention. Further, we measured expected and perceived performance with visual analog scales and assessed trait anxiety, change in state anxiety, optimism, holistic thinking, persistence, and cooperation with questionnaires. The intervention did not affect actual test performances; similarly, trait and state variables and expectations did not have an impact. Furthermore, the experimental manipulation and trait and state variables did not significantly affect perceived performance. However, the association between expectation and perceived performance was strong (ϱ = 0.627, p < 0.001). These findings suggest that postural stability is not susceptible to placebo and nocebo influences. Still, there is a dissociation between objective and subjective performance, showing that expectations impact perceived but not actual performance, which could fuel motivation in rehabilitation settings.

Effects of vestibular rehabilitation in patients with unilateral vestibular hypofunction

Purpose: To investigate the effect of physiotherapy on the balance parameters and fall risk in patients with unilateral vestibular hypofunction (UVH). Patients and Methods: Thirty patients diagnosed with UVH were included in the study. The number of falls, Visual Analog Scale, Modified Clinical Test for Sensory Interaction in Tandem and Balance, and dynamic visual acuity assessments was performed before and after treatment. The patients were included in an individual treatment program for 8 weeks. Physiotherapy sessions were given at 2-week intervals. Along with the level of development of the treatment applied to the patients, it was requested perform a home exercise program with ten repetitions three times a day. Results: After 8 weeks of vestibular rehabilitation, it was observed that the balance parameters of the participants improved and the number of falls decreased. Statistically significant results were obtained in the Eyes-closed Tandem test (P = 0.001). Significant changes occurred in the modified Clinical Test results for Sensory Interaction in Balance from 0.37 ± 0.19 s to 0.93 ± 0.11 s (P = 0.001). Vestibular symptoms and dynamic visual acuity scores also improved after treatment (P = 0.001). Conclusion: It was concluded that the physiotherapy program applied to our patients with UVH positively affected fall risk and significantly improved balance parameters.

Predicting Falls in Older Adults with an Accelerometer-Based Smartphone App

Purpose This study investigated the accuracy of an accelerometer-based smartphone application for predicting the risk of falls in older adults. Methods Eighty community-dwelling older adults (70.05 ± 4.5 years) were assessed using an accelerometer-based smartphone application for balance assessment at baseline, which included 1) the Modified Clinical Test of Sensory Interaction in Balance (MCTSIB), 2) a single-leg stance (SLST), and 3) limit of stability (LOS) test. The fall incidence during a 6-month follow-up was recorded. The area under the receiver operating characteristic curve (AUC) was used to determine accuracy. Results The accuracy in predicting falls of all assessments was high (AUC = 0.78–0.99). The MCTSIB had the highest AUC (0.99) compared with the SLST (0.86) and the LOS test (0.78). The MCTSIB had a cutoff score of 8.04, sensitivity of 100%, and specificity of 98%. Conclusion The accelerometer-based smartphone application could predict falls in older adults with excellent accuracy.

Smartphone-based gait and balance accelerometry is sensitive to age and correlates with clinical and kinematic data

BackgroundThe Gait&Balance (G&B) App has produced valid and reliable measures of gait and balance in young healthy adults but has not been tested in older adults. Research questionIn healthy middle-to-older aged adults, are G&B App measurements sensitive to age, valid against clinical and kinematic measures, and reliable? MethodHealthy participants (n = 34, 14 male, 42–94 years) completed the G&B App protocol three times within a single session. 3D kinematics were collected concurrently. Clinical balance measures were collected (Modified Clinical Test of Sensory Interaction in Balance (mCTSIB), Mini Balance Evaluation Systems Test (MBT), and Functional Gait Assessment (FGA)). Sensitivity to age was assessed with Pearson’s correlations. Validity tests included Pearson’s correlations and Bland-Altman limits of agreement. Reliability tests included intra-class correlation coefficients and standard error of the measure. ResultsDuring quiet stance on a compliant surface, the G&B App was sensitive to age-related differences not detectable with the mCTSIB. During walking tasks, there was adequate convergent validity between the MBT and G&B App measures of step length, and between the FGA and G&B App measures of walking speed, step length, and periodicity. The G&B App had moderate-to-excellent validity against 3D kinematics for postural stability during quiet stance (r 0.98 [0.98, 0.99]), step time (r 0.97 [0.96, 0.98]), walking speed (r 0.79 [0.7, 0.86]), and step length (r 0.73 [0.61, 0.81]). Test-retest reliability was moderate-to-excellent for G&B App measures of postural stability, walking speed, periodicity, step length, and step time. G&B App measures of step length asymmetry, step length variability, step time asymmetry, and step time variability had poor validity and reliability. SignificanceThe G&B App was sensitive to age-related differences in balance not detectable with clinical measurement. It provides valid and reliable measures of postural stability, step length, step time, and periodicity, which are not currently available in standard practice.

Methodology: This was an experimental study design 60 samples were selected based on the inclusion criteria, Group A received balance and Proprioception exercise and Group B conventional exercise. Pre and posttest measurement were taken and compared by using outcome measures of VAS, Four-Square Step Test and Modified Clinical Tests of Sensory Interaction in Balance. Results: On comparing the mean value of Group A and Group B, shows significant difference between group A and group B. Group A Balance and proprioception exercise seems to be more effective than Group B conventional exercises.

Effectiveness of vestibular rehabilitation therapy in patients with idiopathic Cerebellar Ataxia with Bilateral Vestibulopathy (iCABV).

To evaluate the benefit of vestibular rehabilitation therapy (VRT) in the management of patients with idiopathic cerebellar ataxia with bilateral vestibulopathy (iCABV). iCABV is a hindbrain degenerative disorder with impairment of both central and peripheral vestibular pathways. There is combined failure of four compensatory eye movement systems including the vestibulo-ocular reflex (VOR), optokinetic reflex, smooth pursuit and the visually enhanced vestibulo-ocular reflex (VVOR). Phenotypic presentation includes postural and gait instability, oscillopsia and dizziness with active head movement. The benefit of VRT in iCABV patients has not been established. A retrospective review was performed on a cohort of twelve patients diagnosed with iCABV in a multidisciplinary neuro-otology clinic. All participated in VRT and completed their suggested course of VRT. The following clinical measures were assessed before starting and after finishing VRT: 1) Dizziness Handicap Inventory (DHI), 2) Activities-Specific Balance Confidence (ABC) Scale, 3) Catastrophization scale, 4) Positive Affective Negative Affective Score (PANAS), 5) Dynamic Gait Index (DGI) and 6) Modified Clinical Test of Sensory Interaction in Balance (mCTSIB). The number of falls historically was recorded in addition to gait speed (ft./sec). Following VRT, patients were found to have improved balance on mCTSIB (condition 4 : 7 vs 18 seconds, P = 0.04) and a better postural stability with a reduced number of falls (p = 0.01). No statistically significant improvement was seen in the DHI, ABC, Catastrophization scale, DGI, PANAS and gait speed (p > 0.05). iCABV patients who underwent VRT were found to have a better postural stability and reduced risk of falls. VRT was not found to significantly improve patients' overall subjective perception of their symptoms or their psychological status.

Preliminary Study of Vibrotactile Feedback during Home-Based Balance and Coordination Training in Individuals with Cerebellar Ataxia.

Intensive balance and coordination training is the mainstay of treatment for symptoms of impaired balance and mobility in individuals with hereditary cerebellar ataxia. In this study, we compared the effects of home-based balance and coordination training with and without vibrotactile SA for individuals with hereditary cerebellar ataxia. Ten participants (five males, five females; 47 ± 12 years) with inherited forms of cerebellar ataxia were recruited to participate in a 12-week crossover study during which they completed two six-week blocks of balance and coordination training with and without vibrotactile SA. Participants were instructed to perform balance and coordination exercises five times per week using smartphone balance trainers that provided written, graphic, and video guidance and measured trunk sway. The pre-, per-, and post-training performance were assessed using the Scale for the Assessment and Rating of Ataxia (SARA), SARAposture&gait sub-scores, Dynamic Gait Index, modified Clinical Test of Sensory Interaction in Balance, Timed Up and Go performed with and without a cup of water, and multiple kinematic measures of postural sway measured with a single inertial measurement unit placed on the participants’ trunks. To explore the effects of training with and without vibrotactile SA, we compared the changes in performance achieved after participants completed each six-week block of training. Among the seven participants who completed both blocks of training, the change in the SARA scores and SARAposture&gait sub-scores following training with vibrotactile SA was not significantly different from the change achieved following training without SA (. However, a trend toward improved SARA scores and SARAposture&gait sub-scores was observed following training with vibrotactile SA; compared to their pre-vibrotacile SA training scores, participants significantly improved their SARA scores ( and SARAposture&gait sub-scores (. In contrast, no significant changes in SARA scores and SARAposture&gait sub-scores were observed following the six weeks of training without SA compared to their pre-training scores immediately preceding the training block without vibrotactile SA (. No significant changes in trunk kinematic sway parameters were observed as a result of training (. Based on the findings from this preliminary study, balance and coordination training improved the participants’ motor performance, as captured through the SARA. Vibrotactile SA may be a beneficial addition to training regimens for individuals with hereditary cerebellar ataxia, but additional research with larger sample sizes is needed to assess the significance and generalizability of these findings.

Identifying Individuals Who Currently Report Feelings of Anxiety Using Walking Gait and Quiet Balance: An Exploratory Study Using Machine Learning.

Literature suggests that anxiety affects gait and balance among young adults. However, previous studies using machine learning (ML) have only used gait to identify individuals who report feeling anxious. Therefore, the purpose of this study was to identify individuals who report feeling anxious at that time using a combination of gait and quiet balance ML. Using a cross-sectional design, participants (n = 88) completed the Profile of Mood Survey-Short Form (POMS-SF) to measure current feelings of anxiety and were then asked to complete a modified Clinical Test for Sensory Interaction in Balance (mCTSIB) and a two-minute walk around a 6 m track while wearing nine APDM mobility sensors. Results from our study finds that Random Forest classifiers had the highest median accuracy rate (75%) and the five top features for identifying anxious individuals were all gait parameters (turn angles, variance in neck, lumbar rotation, lumbar movement in the sagittal plane, and arm movement). Post-hoc analyses suggest that individuals who reported feeling anxious also walked using gait patterns most similar to older individuals who are fearful of falling. Additionally, we find that individuals who are anxious also had less postural stability when they had visual input; however, these individuals had less movement during postural sway when visual input was removed.

Innovative System for Evaluation and Rehabilitation of Human Imbalance.

&lt;b&gt;Introduction:&lt;/b&gt; Mobile posturography is based on wearable inertial sensors; it allows to test static stability (static posturography) and gait disturbances. &lt;/br&gt; &lt;/br&gt; &lt;b&gt;Aim:&lt;/b&gt; The aim of this work was to present the results of research on the innovative MEDIPOST system used for diagnosis and rehabilitation of balance disorders. &lt;/br&gt; &lt;/br&gt; &lt;b&gt;Material and methods:&lt;/b&gt; Fourteen articles published in influenced foreign journals were presented and discussed. The deve-lopment and construction of the device was preceded by a literature review and methodological work. The Dizziness Handi-cap Inventory (DHI) questionnaire was translated and validated. The methodology of posturography with head movements with a frequency of 0.3 Hz was also developed in the group with chronic vestibular disorders. Simultaneous measurements were performed (static posturogrphy vs. MEDIPOST) in the CTSIB-M (Modified Clinical Test of Sensory Interaction in Balance) test in healthy subjects and patients with unilateral peripheral dysfunction.&lt;/br&gt; &lt;/br&gt; &lt;b&gt;Results:&lt;/b&gt; In the posturography with head movements the improvement of sensitivity (67 to 74%) and specificity (65 to 71%) was noted. In the CTSIB-M test the intraclass correlation coefficients for both methods were 0.9. The greatest differences between examinations were observed for the mean angular velocity in the tests on the foam (trials no. 3 and 4), in particular on the foam with eyes closed (trial no. 4 - sensitivity 86.4%, specificity 87.7%). Two functional tests were analyzed: the Swap Seats test and the 360 degree turn test. In the former, the results are studied from 6 sensors - 86% of the true positives and 73% of the true negatives for the fall/ no-fall group classification. The second test differentiates people with vestibular impairment and healthy people. It can be analyzed with 1 (sensitivity 80%) and 6 sensors (sensitivity 86%, specificity 84%). Currently, the MEDIPOST device is in the development and certification phase.

Examining the Relationship Between a Neuromuscular Control Baseline Battery for Sport-Related Concussion and Anterior Cruciate Ligament Injury Risk

To examine the relationship between the m-CTSIB and Landing Error Scoring System in a sample of collegiate female athletes. Recent literature has linked concussion and neuromuscular deficits in the lower extremity after injury. Neuromuscular control is frequently assessed using balance measures for concussion, but also dynamically to identify anterior cruciate ligament injury (ACL) risk via jump-landing movement screening. Thirty-nine healthy, collegiate female soccer (n = 22) and volleyball (n = 17) athletes completed the modified-Clinical Test of Sensory Interaction of Balance (m-CTSIB) and the Landing Error Scoring System (LESS). Measures consisted of total m-CTSIB sway index scores on individual conditions (firm surface eyes open [condition 1] and eyes closed [2], foam surface eyes open [3] and eyes closed [4]), m-CTSIB overall score, and total LESS errors. LESS scores were also categorized into a low (0-4 errors) and high (5 + errors) risk to determine if athletes with worse neuromuscular control on the LESS has worse balance on the m-CTSIB. A Spearman's rank-order correlation was conducted to determine the strength of the relationship between LESS and m-CTSIB performance. A series of Mann-Whitney U test were performed to determine differences between low and high LESS performance on m-CTSIB performance. There was a weak, negative correlation between LESS and m-CTSIB performance (rs(37) = -0.153, p = 0.35). Further, there were no differences between the low and high risk LESS groups on sway index scores on conditions 1 (U = 158.5, p = 0.39), 2 (U = 156.0, p = 0.36), 3 (U = 165.5, p = 0.51), or 4 (U = 128.5, p = 0.08), as well as overall m-CTSIB scores (U = 150.5, p = 0.28). There appears to be a lack of relationship between the LESS and m-CTSIB tests, revealing the independence of static and dynamic lower extremity neuromuscular function. Athletes who may be more at risk for ACL injury due to abnormal jump-landing biomechanics, do not differ from low-risk athletes on baseline balance assessment.

The Effects of Exergaming on Sensory Reweighting and Mediolateral Stability of Women Aged Over 60: Usability Study.

BackgroundOlder adults tend to experience difficulties in switching quickly between various reliable sensory inputs, which ultimately may contribute to an increased risk of falls and injuries. Sideward falls are the most frequent cause of hip fractures among older adults. Recently, exergame programs have been confirmed as beneficial tools for enhancing postural control, which can reduce the risk of falls. However, studies to explore more precisely which mechanism of exergaming directly influences older women’s ability to balance are still needed.ObjectiveOur aim was to evaluate, in a single-group pretest/posttest/follow-up usability study, whether Kinect exergame balance training might have a beneficial impact on the sensory reweighting in women aged over 60.MethodsA total of 14 healthy women (mean age 69.57 [SD 4.66] years, mean body mass index 26.21 [SD 2.6] kg/m2) participated in the study. The volunteers trained with the commercially available games of Kinect for Xbox 360 console 3 times (30 minutes/session) a week over a 6-week period (total of 18 visits). Participants’ postural sway in both the anteroposterior (AP) and mediolateral (ML) directions was recorded with NeuroCom Balance Master 6.0. To assess and measure postural sensory reweighting, the Modified Clinical Test of Sensory Interaction in Balance was used, where volunteers were exposed to various changes in visual (eyes open or eyes closed) and surface conditions (firm or foam surface).ResultsIn the ML direction, the Kinect exergame training caused a significant decrease in the sway path on the firm surface with the eyes open (P<.001) and eyes closed (P=.001), and on the foam surface with the eyes open (P=.001) and eyes closed (P<.001) conditions compared with baseline data. The follow-up measurements when compared with the baseline data showed a significant change in the sway path on the firm surface with the eyes open (P<.001) and eyes closed (P<.001) conditions, as well as on the foam surface with the eyes open (P=.003) and eyes closed (P<.001) conditions. Besides, on the firm surface, there were no significant differences in sway path values in the AP direction between the baseline and the posttraining measurements (eyes open: P=.49; eyes closed: P=.18). Likewise, on the foam surface, there were no significant differences in sway path values in the AP direction under both eyes open (P=.24) and eyes closed (P=.84) conditions.ConclusionsThe improved posturography measurements of the sway path in the ML direction might suggest that the Kinect exergame balance training may have effects on sensory reweighting, and thus on the balance of women aged over 60. Based on these results, Kinect exergaming may provide a safe and potentially useful tool for improving postural stability in the crucial ML direction, and thus it may help reduce the risk of falling.

Investigating the Effect of Hearing Aid Use on the Balance Status of Children with Severe to Profound Congenital Hearing Loss Using the Pediatric Clinical Test of Sensory Interaction for Balance.

Since the hearing and vestibular organs are close to each other, the correlation between hearing and balance is one of the principal issues, especially in people with hearing loss. In this study, the effect of the auditory system on human balance performance was investigated by comparing the balance status of hearing-impaired children in the aided and unaided situations. In this cross-sectional study a group of children were assigned the task to compare the balance sways in two aided and unaided situations. A total of 90 children aged 7 to 10 years with severe to profound congenital hearing loss and the healthy vestibular system of both genders served as the research population. After a complete evaluation of the hearing and vestibular system and validation of the hearing aid performance, body sway was recorded using the pediatric clinical test of sensory interaction for balance in aided and unaided situations in the presence of background noise from the speaker. According to this study, there was no difference in body sway in aided and unaided situations for conditions 1, 2, and 3. In comparison, in conditions 4, 5, and 6 of the test, there was a statistically significant difference in body sway between aided and unaided situations. However, there was no difference in the sway of the body in aided and unaided situations between girls and boys. According to this study, hearing aids can improve balance in challenging listening environments.

ASSESSMENT OF BALANCE FUNCTIONS AND PRIMITIVE REFLEXES IN CHILDREN WITH LEARNING DISABILITY

Background: Persistence of primary reflexes can indicate poor neurological development and immaturity within the nervous system. As dyslexia is a neurodevelopmental disorder that involves more than just reading difficulties so it’s important to investigate primitive reflexes and balance functions in dyslexics. Aim of the Work: To assess balance functions, primitive reflexes in dyslexics. Subjects and Methods: The present study was conducted on 60 children divided into two subgroups. Control group consists of 20 normal children and study group consists of 40 children with dyslexia (diagnosed by Arabic Reading Screening test (ARST) and Modified Arabic Dyslexia Screening Test (MADST). Both study and control groups aged from 6 6/12 to 9 years old. They were subjected to clinical diagnostic tests for primitive reflexes and balance office tests (Romberg, unilateral stance, Fukuda stepping test, modified clinical test of sensory interaction in balance (mCTSIB). Results: The study group demonstrated poor balance measured with unilateral stance compared to control group. Sixty percent of the study group has retained primitive reflexes. Conclusions: Dyslexic children have poor balance compared to normal children and they have retained primitive reflexes supporting poor neurological development. Assessment of balance functions is recommended to be included within the test battery of dyslexics for better quality of life.

The Utility of Neuromotor Retraining to Augment Manual Therapy and Vestibular Rehabilitation in a Patient with Post-Concussion Syndrome: A Case Report

Background and PurposeLess than half of patients discharged from the emergency department post-concussion receive patient education or follow-up care, and 10-20% of individuals will develop symptoms that last longer than six months. Current research on interventions for post-concussion syndrome (PCS) shows inconsistent results, and recommendations for effective physical therapy treatment for patients with chronic PCS are lacking. The purpose of this case report is to highlight a successful, multi-system approach to physical therapy examination and treatment of a patient with chronic PCS.Case DescriptionThis case describes a 21-year-old male who sustained a concussion 356 days prior to evaluation. He received no follow-up treatment and reported periods of worsening symptoms since the injury. Impairments in cervical range of motion and accessory mobility, vestibular and vestibulo-ocular function, and postural stability were identified. Both cognitive and emotional symptoms were also present. The patient attended eight, sixty-minute sessions over a five-week period in an outpatient setting. Comprehensive physical therapy interventions included manual therapy, vestibular rehabilitation, and neuromotor retraining aimed at restoring proper sensory integration and midline postural orientation.OutcomesOutcomes included cervical spine goniometric measurements and accessory mobility assessments. Objective measures of postural stability included the Modified Clinical Test of Sensory Interaction in Balance (m-CTSIB) and the Fukuda Step Test. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) was used to subjectively assess symptom severity. At discharge, goniometric measurements returned to within normal limits except left cervical rotation active range of motion (ROM), and both the m-CTSIB and Fukuda Step Test were within normal ranges. The RPQ score reduced from 20 to 2 demonstrating symptom resolution in all items but “headache.”DiscussionPCS can affect multiple systems, necessitating a comprehensive approach to examination and intervention. Manual therapy was used to restore cervical spine ROM, vestibular rehabilitation was utilized to improve gaze stability and visual motion sensitivity, and neuromotor retraining was implemented to improve postural stability and sensory integration. Physical therapists have the ability to treat multiple systems impacted with PCS, with the potential to reduce the longevity and severity of impairments for patients.Level of EvidenceLevel V

The effects of age at cochlear implantation on balance in children: A pilot study.

The evaluation of the effects of age at cochlear implantation on balance in children. Cross-sectional study. Twenty children who received their cochlear implants (CI) before the chronologic age of 48 months (Early CI Group), and 20 children who received their CI at 48 months chronologic age or later (Late CI Group). All children underwent Tandem Romberg (TR) test, Single-Leg stance (SLS) test, Pediatric Clinical Test of Sensory Interaction for Balance (P-CTSIB), Pediatric Balance scale (PBS) and Timed Up and Go (TUG) test. The scores of TR, SLS and P-CTSIB and TUG tests and PBS were recorded. Mann Whitney U test and Independent-samples t-test were used to compare data between groups. TR (eyes opened-EO), SLS (EO), PBS, and TUG scores and incidence in dizziness symptoms did not show significant differences between the groups (p > 0.05). Duration of TR and SLS tests (eyes closed-EC), P-CTSIB-positions 5, and 6 were significantly longer in the Early CI Group than the Late implanted group(p < 0.05). Although the age of cochlear implantation did not affect functional balance for children, it has been found to cause impaired balance performance in difficult static conditions and increased frequency of dizziness.
