RESUMO
Introduction: Cerebral palsy (CP) is a lifelong disorder of posture and movement which often leads to a myriad of limitations in functional mobility. The Functional Mobility Scale (FMS) is a parent-report measure of functional mobility for children with CP at three different distances (5 m, 50 m, and 500 m). This is a cross-sectional study which sought to translate and culturally adapt the FMS into Arabic and to validate the translated version. Functional mobility for children and adolescents with CP in Saudi Arabia was examined. Methods: The translation methodology complied with the World Health Organization Disability Assessment Schedule 2.0 translation package. A total of 154 children with CP were recruited (mean age 8.16 ± 3.32 years). Parents were interviewed to rate the usual walking ability of their children on the Arabic FMS. The re-test assessment was done with 34 families. The mean time interval between the first and second sessions was 14.3 days (SD = 8.5), with a range of 6-37 days. Results: Concurrent validity was explored using Spearman's rank correlation coefficient between scores of the Arabic FMS with their corresponding score on the Gross Motor Function Classification System (GMFCS). Spearman's r values ranged between (-0.895 and -0.779), indicating strong to very strong correlations. The Test-retest reliability was examined using Cohen's weighted kappa, which showed almost perfect agreements. There was greater limitation for functional mobility at longer distances as 55.2% of children could not complete 500 meters (FMS score N). Overall, there was limited use of wheelchairs for all distances (ranging from 9.1% to 14.3%). Levels IV and V on the GMFCS had less variation in FMS scores and most of the children in these levels either did not complete the distances (no functional mobility at all distances) or used a wheelchair for mobility. Discussion: The Arabic FMS was shown to be a reliable and valid measure of functional mobility for children with CP in their environment based on the parental reports. Functional mobility varied at different distances and within each GMFCS level. The use of both the GMFCS and FMS when assessing children with CP is recommended.

A simple, valid, and reliable self-assessment fall-risk questionnaire in Arabic is needed to significantly promote awareness and develop fall-prevention programs. This study translated and adapted the Fall Risk Questionnaire (FRQ) into Arabic and determined its validity and reliability among Saudi Arabian older adults in two phases: (1) cross-culturally adapting the FRQ into Arabic and (2) assessing the adapted questionnaire's psychometric properties in two sessions with 110 Arabic-speaking participants aged ≥65 years. Pearson's r showed that the Arabic FRQ had a significant moderate negative relationship with the Berg Balance Scale and fair-to-moderate positive correlations with Five Time Sit to Stand and Time Up and Go. The receiver operating characteristic curve indicated a significant area under the curve = 0.81. The cut-off score was 7.5 and associated with 73.7% sensitivity and 73.6% specificity. Internal consistency was estimated as good, with Cronbach's α = 0.77. Deletion of item 1 slightly increased Cronbach's α to 0.78. The Arabic FRQ demonstrated excellent test-retest reliability, with an intraclass correlation coefficient = 0.95 (95% CI: 0.92-0.97). It is highly valid and reliable in providing valuable data for evaluating fall risk in adults aged ≥65 years and for consulting a specialist for further investigation if necessary.

Introduction: Dizziness is one of the most common and recurring complaints in adults presenting at the clinic. However, its prevalence in the population of the Kingdom of Saudi Arabia remains unclear. We aimed to examine the prevalence and correlates of dizziness in a large sample of the Saudi population. Methods: In this is cross-sectional study, we used an electronic survey, which was completed by 1.478 respondents, with a response rate of 84% across five regions of Saudi Arabia. The online survey was launched on the Qualtrics website and distributed via social media channels to obtain heterogeneous responses. The study included adults aged ≥18 years who resided in Saudi Arabia during data collection. We used t-test and chi-square test for descriptive analysis and multiple logistic regression model to assess prevalence and predictors of dizziness. Results: More than half of the participants were aged between 26 years and 45 years (58.66%). Of the participants, 42.97% reported having dizziness at the time of taking the survey. Women were less likely than men to report dizziness (OR = 0.65; CI, 0.49, 0.87; p = 0.003). A description of the type of dizziness by age revealed that vertigo slightly decreased with age. Unclear vision with movement or blurry vision was common in young adults, whereas imbalance was common in older adults. A multiple regression model adjusted for demographic characteristics revealed a statistically significant association between dizziness and age group. Participants in the age group of 46-55 years were 1.83 times more likely to report dizziness compared to those aged >65 years (odds ratio = 1.83; confidence interval, 0.62, 5.41; p = 0.0009). Discussion: Dizziness is a common complaint in Saudi Arabia. Future studies should elucidate the risk factors for and mechanisms of dizziness to help prevent falls and reduced quality of life.
RESUMO
BACKGROUND: Chronic motion sensitivity (CMS) is a combination of autonomic symptoms provoked by exposure to motion. The correlation between anxiety and CMS is not yet well understood. OBJECTIVES: 1) To compare median anxiety levels between young adults with and without CMS. 2) To examine the effect of anxiety on postural stability with immersion virtual reality. 3) To compare anxiety levels between sexes. METHODS: Participants included 60 adults (20-40 years), with and without CMS. After determining their current and general anxiety levels, postural stability was measured. RESULTS: There were significant differences in median (minimum, maximum) state- and trait-anxiety scores between participants with and without CMS, but no significant differences in median state- and trait-anxiety scores between males and females with CMS. There was a significant inverse relationship between state- and trait-anxiety scores and postural stability (ρ=â-0.28, pâ=â0.03, and ρ=â-0.32, pâ=â0.01, respectively). The stepwise regression analysis showed the Motion Sickness Susceptibility Questionnaire-Short Form score to be the only variable contributing significantly to postural stability (R2â=â26.2%; tâ=â-4.5, pâ<â0.001). CONCLUSIONS: Young adults with CMS are more anxious, although anxiety does not contribute to postural stability in this group. Anxiety levels do not appear to differ between young adult males and females with CMS.

BACKGROUND: Motion sensitivity, or motion sickness, is common in modern vehicular and visually stimulating environments. Several studies have shown a relationship between motion sensitivity and decreased postural stability. We aimed to evaluate the effects of head motion (horizontal and vertical) on postural stability in healthy adults with and without chronic motion sensitivity (CMS). METHODS: Sixty healthy adult men and women (age, 20-40 years) with CMS (CMS group, n = 30) and without CMS (non-CMS group, n = 30) participated in the study. Postural stability was assessed during three conditions (static, horizontal head motion, and vertical head motion) using computerized dynamic posturography. Group and condition-related differences in equilibrium scores were evaluated. RESULTS: There was no significant group x condition interaction (F2,114 = 0.9, partial Æ2 = 0.04, p = 0.35). However, significant condition-related differences in equilibrium scores were observed (F2,114 = 26.4, partial Æ2 = 0.31, p < 0.001). Equilibrium scores were significantly worse in the horizontal and vertical head motion conditions compared to those in the static condition (p < 0.001), but were comparable in vertical and horizontal head motion conditions (p = 0.27). CONCLUSIONS: Postural stability was lower in the horizontal and vertical conditions compared to the static condition. However, horizontal and vertical head motions had comparable effects on postural stability in both CMS and non-CMS groups, contrary to our expectations.
RESUMO
BACKGROUND AND PURPOSE: Motion sensitivity is a common condition among the general population and may be accompanied by postural instability and anxiety. Preliminary studies suggest that minimal dosage of gaze stability exercises improves postural stability in young adults with chronic motion sensitivity. The aim of this study was to investigate the effect of progressive gaze stability exercises on postural stability, motion sensitivity, and anxiety in healthy young adults with chronic motion sensitivity. METHODS: We conducted a single-blind randomized controlled trial to assess the effect of gaze stability exercises on chronic motion sensitivity. Forty-one participants of both genders ages 20 to 40 years with chronic motion sensitivity were randomly assigned to 2 groups. The intervention group performed gaze stability exercises while the sham group performed saccadic eye movement exercises for 6 weeks. Computerized Dynamic Posturography with Immersion Virtual Reality (CDP-IVR)-condition 1 (C1) and condition 2 (C2)-Motion Sensitivity Quotient (MSQ), Motion Sickness Sensitivity Susceptibility Questionnaire Short Form (MSSQ-Short: MSA, MSB), and State-Trait Anxiety Inventory for Adults (STAI Form Y-2) were the outcome measures used. RESULTS: There was no significant group × time interaction for MSA, MSB, MSSQ percentile, STAI, MSQ, C1 mean, or C2 mean. However, posttreatment a significant difference in the mean CDP-IVR score of C2 was identified between the 2 groups. For C2, the intervention group demonstrated a 117% increase in the mean CDP-IVR score compared with a 35.2% increase in the sham group. MSQ reduced significantly from baseline to 6 weeks postintervention in the intervention group (4.0 ± 1.2 vs 1.9 ± 0.9). Anxiety was significantly reduced in the sham group only (38.2 ± 1.9 vs 35.8 ± 2.2). DISCUSSION AND CONCLUSIONS: Based on the results of this study, progressive gaze stability exercises appear to have value for managing chronic motion sensitivity in healthy young adults. Further research with larger sample size and broader age range is needed to generalize these findings.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A203).

BACKGROUND: Chronic motion sensitivity (CMS) has been defined as a feeling of un-wellness elicited by either actual or perceived motion. CMS is a common condition and is more prevalent in females than in males. In addition to a variety of symptoms, young adults with CMS have less postural stability than those without CMS. OBJECTIVE: To determine whether dependence on visual cues for postural stability is different between young adults with and without CMS, and whether it differs by gender within each group. METHODS: Sixty young adults (30 females and 30 males) were assigned to one of two groups (CMS or non-CMS) using the Motion Sickness Susceptibility Questionnaire-Short Form. Postural stability was measured for all participants using the Bertec Balance Advantage-Computerized Dynamic Posturography with Immersion Virtual Reality. RESULTS: A significant difference was found in mean postural stability scores during immersion virtual reality between the CMS and non-CMS groups (pâ<â0.001); however, no significant difference was shown in mean postural stability between males and females within the CMS and non-CMS groups (pâ=â0.10 and pâ=â0.97, respectively). CONCLUSION: The results suggest that young adults with CMS are over-reliant on visual cues for postural stability, and that visual dependence is not influenced by gender.

BACKGROUND AND PURPOSE: The risk of falling for older adults increases in dimly lit environments. Longer sitting pause times, before getting out of bed and standing during the night, may improve postural stability. The purpose of this study was to measure the effect of sitting pause times on postural sway velocity immediately after a supine to standing transfer in a dimly lit room in older adult women. METHODS: Eighteen healthy women aged 65 to 75 years who were able to independently perform supine to standing transfers participated in the study. On each of 2 consecutive days, participants assumed the supine position on a mat table and closed their eyes for 45 minutes. Then, participants were instructed to open their eyes and transfer from supine to sitting, with either 2- or 30-second pause in the sitting position followed by standing. The sitting pause time order was randomized. RESULTS: A significant difference was observed in postural sway velocity between the 2- and 30-second sitting pause times. The results revealed that there was less postural sway velocity after 30-second than 2-second sitting pause time (0.61 ± 0.19 vs 1.22 ± 0.68, P < .001). DISCUSSION: Falls related to bathroom usage at night are the most common reported falls among older adults. In the present study, the investigators studied the effect of sitting pause times on postural sway velocity after changing position from supine to standing in a dimly lit environment. The findings showed that the mean postural sway velocity was significantly less after 30-second sitting pause time compared with 2-second sitting pause time. CONCLUSIONS: Postural sway velocity decreased when participants performed a sitting pause of 30 seconds before standing in a dimly lit environment. These results suggest that longer sitting pause times may improve adaptability to dimly lit environments, contributing to improved postural stability and reduced risk of fall in older adult women when getting out of bed at night.
