Home-based gait speed and the association with sociodemographic and anthropometric variables: A national study (ELSI-Brazil).

OBJECTIVES: To investigate home-based gait speed performance for men and women stratified by age group and its associations with sociodemographic and anthropometric variables. METHODS: Data from the 2nd wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil, 2019-2021) were used. Gait speed was tested twice at home over 3.0 meters at usual pace. Associations of sociodemographic and anthropometric variables with gait speed were evaluated using gamma regression. RESULTS: Median gait speed value reduced with increasing age in both sexes [men: 0.70 m/s (50-59 years) to 0.53 m/s (≥80 years); women: 0.68 m/s (50-59 years) to 0.48 m/s (≥80 years)] and was significantly lower in women than men in the age groups of 60-69 and 70-79 years. Age group and education among men and age group, education, and waist circumference among women were significantly associated with gait speed. CONCLUSIONS: Our findings may be helpful as reference values to identify mobility limitation among older Brazilians.

Do Older Brazilian Women Who Participate in a Regular Physical Exercise Program Have Higher Habitual Physical Activity Levels? A Cross-Sectional Study Based on Accelerometer Data.

A cross-sectional study was conducted to compare the habitual physical activity level, measured by accelerometry, gait performance, assessed by the GAITRite® system, handgrip strength, and static balance between older Brazilian women who participate (n = 50; 70.7 ± 5.5 years) and do not participate (n = 50; 70.1 ± 5.6 years) in a regular physical exercise program, and to investigate whether participation in a regular exercise program ensures compliance with physical activity recommendations. Older women who participated in a regular physical exercise program had significantly shorter sedentary activity time (effect size [ES] = 0.54), longer moderate activity time (ES = 0.85), and higher energy expenditure (ES = 0.64), number of steps (ES = 0.82), gait speed (ES = 0.49), and step length (ES = 0.45). However, regular participation in an exercise program did not guarantee compliance with physical activity recommendations. Behavioral changes to increase physical activity levels among older women who do and do not participate in a regular exercise program are necessary.

Effectiveness of exercises by telerehabilitation on pain, physical function and quality of life in people with physical disabilities: a systematic review of randomised controlled trials with GRADE recommendations.

OBJECTIVE: Investigate whether exercise-based telerehabilitation improves pain, physical function and quality of life in adults with physical disabilities. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES: Searches were performed in AMED, MEDLINE, CINAHL, SPORTDiscus, Embase, PEDro, Cochrane Library and PsycINFO. ELIGIBILITY CRITERIA: Trials were considered if they evaluated exercise by telerehabilitation. The population included adults with physical disability. Comparisons were control and other interventions. The outcomes were pain, physical function and quality of life. Study selection, data extraction and analysis followed the protocol registered in PROSPERO (CRD42019122824). GRADE determined the strength of evidence. RESULTS: Forty-eight trials were included in the quantitative analysis. When compared with other interventions, there was high-quality evidence that telerehabilitation was not different to other interventions for pain (95% CI: -0.4 to 0.1), physical function (95% CI: -0.2 to 0.2) and quality of life (95% CI: -0.1 to 0.5) at long-term. There was moderate-quality evidence that telerehabilitation was not different to other interventions for physical function (95% CI: -0.1 to 0.5) and quality of life (95% CI: -0.2 to 0.5) at short-term. However, due to the low-quality evidence and the small number of trials comparing exercise protocols offered by telerehabilitation with control groups, it is still not possible to state the efficacy of telerehabilitation on pain, function and quality of life at short-term and long-term. CONCLUSIONS: Exercise by telerehabilitation may be an alternative to treat pain, physical function and quality of life in adults with physical disabilities when compared with other intervention.

Validity of balance and mobility screening tests for assessing fall risk in COPD.

People with chronic obstructive pulmonary disease (COPD) have balance impairments and an increased risk of falls. The psychometric properties of short balance tests to inform fall risk assessment in COPD are unknown. Our objective was to determine the validity (concurrent, convergent, and known-groups) of short balance and mobility tests for fall risk screening. Participants with COPD aged ≥ 60 years attended a single assessment. Correlation coefficients described the relationships between the Brief Balance Evaluation Systems Test (Brief BESTest), Single-Leg Stance (SLS), Timed Up and Go (TUG), and Timed Up and Go Dual-Task (TUG-DT) tests, with the comprehensive Berg Balance Scale (BBS), chair-stand test, and measures of exercise tolerance, functional limitation, disability, and prognosis. Independent t-tests or Mann-Whitney U tests were used to examine differences between groups with respect to fall risk. Receiver operating characteristic curves examined the ability of the screening tests to identify individuals with previous falls. A total of 86 patients with COPD completed the study (72.9 ± 6.8 years; forced expiratory volume in 1 second: 47.3 ± 20.3% predicted). The Brief BESTest identified individuals who reported a previous fall (area under the curve (AUC) = 0.715, p = 0.001), and the SLS showed borderline acceptable accuracy in identifying individuals with a fall history (AUC = 0.684, p = 0.004). The strongest correlations were found for the Brief BESTest and SLS with the BBS (r = 0.80 and r = 0.72, respectively) and between the TUG and TUG-DT with the chair-stands test (r = 0.73 and r = 0.70, respectively). The Brief BESTest and SLS show the most promise as balance screening tools for fall risk assessment in older adults with COPD. These tests should be further evaluated prospectively.

Analysis of symmetry between lower limbs during gait of older women with bilateral knee osteoarthritis.

BACKGROUND: Osteoarthritis (OA) is a common condition in older adults, with high epidemiological, clinical, and economic burden worldwide. In clinical practice, patients with knee OA often walk with abnormal gait patterns because of pain, stiffness and/or mobility dysfunctions. Therefore, assessing the symmetry of the lower limbs might improve the rehabilitation treatment and prescription of walking devices. AIMS: To compare the symmetry of step length and single support phase between lower limbs during gait of older women with bilateral knee OA and asymptomatic controls, and to verify if there is difference between these two groups in relation to velocity, cadence, step length and single support phase. METHODS: This cross-sectional study included a convenience sample of 66 community-dwelling older women aged ≥ 65 years with a medical diagnosis of symptomatic bilateral knee OA (n = 33) and asymptomatic controls (n = 33), matched by age and body mass index. All gait parameters were obtained using the GAITRite® system. RESULTS: Mean age of the sample was 72.6 ± 4.0 years. Participants with OA walked with lower velocity (p = 0.001), cadence (p = 0.009) and step length bilaterally (both p = 0.001). No significant difference was found between groups in the symmetry of step length between lower limbs, single support phase and symmetry of single support phase between lower limbs. CONCLUSION: Older women with bilateral knee OA walk with lower velocity, cadence and step length, but have the same symmetry in the step length and single support phase between lower limbs as asymptomatic older women.

The geriatric depression scale and the timed up and go test predict fear of falling in community-dwelling elderly women with type 2 diabetes mellitus: a cross-sectional study.

BACKGROUND: Fear of falling is a common and potentially disabling problem among older adults. However, little is known about this condition in older adults with diabetes mellitus. The aims of this study were to investigate the impact of the fear of falling on clinical, functional and gait variables in older women with type 2 diabetes and to identify which variables could predict the fear of falling in this population. METHODS: Ninety-nine community-dwelling older women with type 2 diabetes (aged 65 to 89 years) were stratified in two groups based on their Falls Efficacy Scale-International score. Participants with a score < 23 were assigned to the group without the fear of falling (n = 50) and those with a score ≥ 23 were assigned to the group with the fear of falling (n = 49). Clinical data included demographics, anthropometrics, number of diseases and medications, physical activity level, fall history, frailty level, cognition, depressive symptoms, fasting glucose level and disease duration. Functional measures included the Timed Up and Go test (TUG), the five times sit-to-stand test (5-STS) and handgrip strength. Gait parameters were obtained using the GAITRite® system. RESULTS: Participants with a fear of falling were frailer and presented more depressive symptoms and worse performance on the TUG and 5-STS tests compared with those without a fear of falling. The group with the fear of falling also walked with a lower velocity, cadence and step length and increased step time and swing time variability. The multivariate regression analysis showed that the likelihood of having a fear of falling increased 1.34 times (OR 1.34, 95 % CI 1.11-1.61) for a one-point increase in the Geriatric Depression Scale (GDS-15) score and 1.36 times (OR 1.36, 95 % CI 1.07-1.73) for each second of increase in the TUG performance. CONCLUSIONS: The fear of falling in community-dwelling older women with type 2 diabetes mellitus is associated with frailty, depressive symptoms and dynamic balance, functional mobility and gait deficits. Furthermore, both the GDS-15 and the TUG test predict a fear of falling in this population. Therefore, these instruments should be considered during the assessment of diabetic older women with fear of falling.

Clinical functional tests help identify elderly women highly concerned about falls.

UNLABELLED: BACKGROUND/STUDY CONTEXT: Limited research exists on functional tests in the discrimination of elderly individuals with high concern about falls from individuals with low concern about falls. The purpose of this study was to determine which functional test best discriminates between elderly women with low and high concern about falls. METHODS: One hundred thirty-five elderly women (72.6 ± 4.8 years) were divided into two groups based on their Falls Efficacy Scale-International score: low concern (n = 56) and high concern (n = 79) about falls. Five functional tests were applied: Timed Up and Go test (TUG), unipodal stance test, five-repetition sit-to-stand test (5-STS), gait velocity, and grip strength. Factorial analysis and discriminant analysis were used. RESULTS: Factorial analysis resulted in three factors that explained 83.8% of the total variance. Factor 1, with 49.5% of total variance explanation, was represented by the TUG, 5-STS, and gait velocity tests and was the only factor to discriminate between the groups, classifying correctly 68.9% of the observations. Among the original variables of Factor 1, the Fisher linear coefficient showed that the TUG was the most discriminant of the tests. CONCLUSION: The TUG test best discriminates elderly women with low and high concern about falls; therefore, it is an important test that should be performed during the assessment of elderly individuals afraid of falling.

Validation of the human activity profile questionnaire as a measure of physical activity levels in older community-dwelling women.

The purpose of this study was to assess the validity of the Human Activity Profile (HAP) by comparing scores with accelerometer data and by objectively testing its cutoff points. This study included 120 older women (age 60-90 years). Average daily time spent in sedentary, moderate, and hard activity; counts; number of steps; and energy expenditure were measured using an accelerometer. Spearman rank order correlations were used to evaluate the correlation between the HAP scores and accelerometer variables. Significant relationships were detected (rho = .47-.75, p < .001), indicating that the HAP estimates physical activity at a group level well; however, scatterplots showed individual errors. Receiver operating characteristic curves were constructed to determine HAP cutoff points on the basis of physical activity level recommendations, and the cutoff points found were similar to the original HAP cutoff points. The HAP is a useful indicator of physical activity levels in older women.

Construct and criterion validity of the functional gait assessment-Brazil in community-dwelling older adults.

BACKGROUND: The functional gait assessment (FGA) is a reliable instrument to evaluate walking balance in the Brazilian older population. However, other measurement properties need investigation. OBJECTIVE: To determine the construct and criterion validity of the FGA-Brazil and its ceiling and floor effects. METHODS: Sociodemographic, clinical, and anthropometric data were collected from 126 older adults. Participants completed the Mini-mental state examination followed by the FGA-Brazil, Berg balance scale (BBS), gait speed, and the Falls Efficacy Scale-International. Six months later, the participants were interviewed by telephone about their fall history. Exploratory factor analysis was used to determine the structural validity. We also determined the construct validity of the FGA-Brazil, using hypothesis testing, by investigating the differences between groups using the Mann-Whitney U test. Criterion validity was determined using the Spearman correlation between the FGA-Brazil and the other balance and gait measures, and using the Receiver Operator Characteristic curve. RESULTS: Participants' mean age was 69.3 ±â€¯7.4 years, and 84 (69.4%) were female. Factor analysis resulted in two factors explaining 53.3% of the total variance. Moderate and high significant correlations were found between the FGA-Brazil and gait speed (r = 0.65) and BBS (r = 0.80). A significant difference in the FGA-Brazil median score between older adults with low and high concern about falls was observed. The cutoff score recommended for predicting falls was 22 or less. No ceiling and floor effects were observed. CONCLUSION: We recommend the FGA-Brazil to determine the risk of falls in community-dwelling older adults.

Cross-cultural adaptation and reliability of the Functional Gait Assessment in older Brazilian adults.

BACKGROUND: The Functional Gait Assessment (FGA) is a standardized instrument for assessing postural stability during various walking tasks. It was developed to increase the reliability and to decrease the potential ceiling effect observed with the Dynamic Gait Index (DGI). OBJECTIVE: To translate and cross-culturally adapt the FGA into Portuguese-Brazilian, and to evaluate its reliability in community-dwelling Brazilian older adults. METHODS: The process of translation and cross-cultural adaptation followed the recommendations of international guidelines. The pre-final version was applied to a sample of 55 older adults of both sexes living independently in the community. For the assessment of reliability (i.e. inter- and intra-rater reliability, standard error of measurement (SEM), and internal consistency), 70 older adults aged 60-87 years were evaluated. RESULTS: There was a conceptual equivalence between the original and the translated versions. All FGA items that used measurements in inches and feet were modified to use matching values in centimeters to reflect the measurement unit used in Brazil. The FGA-Brazil showed excellent inter- and intra-rater reliability (ICC2,1 > 0.90), low SEM (ranging from 1.03 to 1.52), and good internal consistency (Cronbach's alpha = 0.858). CONCLUSION: The FGA-Brazil is a semantically and linguistically valid and reliable instrument to assess walking balance among community-dwelling older adults.

Cross-cultural validity of the Animated Activity Questionnaire for patients with hip and knee osteoarthritis: a comparison between the Netherlands and Brazil.

BACKGROUND: The Animated Activity Questionnaire (AAQ) was developed in the Netherlands to assess activity limitations in individuals with hip/knee osteoarthritis (HKOA). The AAQ is easy to implement and minimizes the disadvantages of questionnaires and performance-based tests by closely mimicking real-life situations. The AAQ has already been cross-culturally validated in six other countries. OBJECTIVE: To assess the cross-cultural validity, the construct validity, the reliability of the AAQ in a Brazilian sample of individuals with HKOA, and the influence of formal education on the construct validity of the AAQ. METHODS: The Brazilian sample (N = 200), mean age 64.4 years, completed the AAQ and the Western Ontario and McMaster Universities Index (WOMAC). A subgroup of participants performed physical function tests and completed the AAQ twice with a one-week interval. The Dutch sample (N = 279) was included to examine Differential Item Functioning (DIF) between the scores obtained in the Netherlands and Brazil. For this purpose, ordinal regression analyses were used to evaluate whether individuals with the same level of activity limitations from the two countries (the Dutch as the reference group) scored similarly in each AAQ item. To evaluate the construct validity, correlation coefficients were calculated between the AAQ, the WOMAC domains, and the performance-based tests. To evaluate reliability, the Cronbach's alpha coefficient, the intraclass correlation coefficient, and the standard error of measurement (SEM) were calculated. RESULTS: The AAQ showed significant correlations with all the WOMAC domains and performance-based tests (rho=0.46-0.77). The AAQ showed high internal consistency (Cronbach's alpha=0.94), excellent test-retest reliability (ICC2,1 = 0.98), and small SEM (2.25). Comparing to the scores from the Netherlands, the AAQ showed DIF in two items, however, they did not impact on the total AAQ score (rho=0.99). CONCLUSION: Overall, the AAQ showed adequate cross-cultural validity, construct validity, and reliability, which enables its use in Brazil and international/multicenter studies.

Brazilian versions of the Measure of Processes of Care-20 and Measure of Processes of Care-Service Providers: translation, cross-cultural adaptation and reliability.

BACKGROUND: The Measure of Processes of Care (MPOC) questionnaires evaluate Family-Centered Practice (FCP) in services for children with developmental disorders. The MPOC-20 and MPOC-SP are completed by parents and by rehabilitation professionals, respectively, and are widely used in several countries. OBJECTIVES: To translate and cross-culturally adapt the MPOC-20 and MPOC-SP to Brazilian Portuguese and evaluate their reliability and internal consistency. METHODS: this study included translation, back-translation, cognitive interviews, testing of the pre-final versions, analysis of reliability and of internal consistency of the final versions. Respondents included parents and rehabilitation professionals from rehabilitation centers in four capital cities in Brazil. RESULTS: Translation and cultural-adaptation procedures ensured the Brazilian versions were understandable and semantically equivalent to the original MPOC-20 and MPOC-SP. Pre-final and final versions were analyzed and vetted by the original authors. The MPOC-20 internal consistency Cronbach's alpha varied between 0.61 and 0.91 (n=107), the test-retest reliability ICC varied between 0.44 and 0.83 and the standard error of measurement varied between 0.66 and 0.85 (n=50). The MPOC-SP internal consistency Cronbach's alpha varied between 0.52 and 0.83 (n=92), the test-retest reliability ICC between 0.83 and 0.90, and the standard error of measure between 0.34 and 0.46 (n=62). CONCLUSION: The Brazilian versions of the MPOC-20 and the MPOC-SP are in general stable and sufficiently reliable. They are relevant to the evaluation of FCP and provide information that can improve health services and ensure better care.

Pelvic floor muscle function in women with and without urinary incontinence: are strength and endurance the only relevant functions? a cross-sectional study.

OBJECTIVES: To investigate if pelvic floor muscle functions (PFMFs), besides strength and endurance, are associated with the occurrence of urinary incontinence (UI) in women, and to investigate which functions predict the occurrence of UI. DESIGN: Cross-sectional study. SETTING: Public health service and community. PARTICIPANTS: Two hundred and ten women (101 with UI and 109 without UI). MAIN OUTCOME MEASURES: PFMF was investigated by the Pelvic Floor Sensory and Muscle Function Exam (Exame das Funções Sensoriais e Musculares do Assoalho Pélvico), a valid and reliable instrument that measures the following functions: tone, reaction, control (contraction), control (relaxation), coordination, strength and endurance. The International Consultation on Incontinence Questionnaire-Short Form was used to document the occurrence and type of UI. Sociodemographic and clinical data were collected through the questionnaire. Chi-squared test, Student's t-test and Mann-Whitney test were used to evaluate the association of each function with UI. Two logistic regression models tested the predictive value of each function for UI: Model a included all of the above PFMFs and Model b included all of the above PFMFs except strength and endurance. RESULTS: Most sociodemographic and clinical risk factors differed between women with UI and women without UI. On univariate analysis, tone, reaction, control (contraction), coordination, strength and endurance were found to be significantly associated (P<0.05) with the occurrence of UI. On multivariate analysis, Model a explained 69% and Model b explained 61% of the likelihood of UI, respectively. CONCLUSIONS: Besides strength and endurance, pelvic floor muscle tone, reaction, control (contraction) and coordination were significantly associated with the occurrence of UI, and should be investigated further.

Reduced version of the Activity Measure for Post-Acute Care (AM-PAC) for inpatients, "6-clicks": Brazilian-Portuguese cross-cultural adaptation and measurement properties.

BACKGROUND: The "6-clicks" is the reduced version of the Activity Measure for Post-Acute Care for inpatients that assesses limitations in basic mobility, daily activity, and applied cognitive, simply and quickly. OBJECTIVE: Cross-culturally adapt the "6-clicks" into Brazilian-Portuguese and verify its measurement properties. METHODS: Cross-cultural adaptation followed recommendations from international guidelines. Reliability indices, standard error of measurement and minimum detectable difference were calculated. Participants included 13 professionals, 13 patients and 13 companions. Test of measurement properties involved 101 patients' of both sexes, hospitalized in the infirmary, under physical therapy care, able to understand and respond to commands and with no discharge expectation. Their 30 companions were also included. RESULTS: Minor changes implemented to the original version. The three domains showed adequate internal consistency (α>0.65). Inter-rater reliability (n=50) and test-retest reliability, when administer to patients (n=51) and to companions (n=30), showed good for basic mobility domain (ICC2.1=0.81, 0.83 and 0.82, respectively), good to moderate for daily activity (ICC2.1=0.78 and ICC3.1=0.71 and 0.82, respectively) and moderate to poor for applied cognitive (ICC2.1=0.64, 0.36 and ICC3.1=0.63), respectively. The highest agreements among patients/companions were also in basic mobility. Standard error of measurement ranged from 2.03 to 2.64 while the minimum detectable difference ranged from 5.63 to 7.32. CONCLUSION: Translated and adapted Brazilian version of the "6-clicks" showed acceptable measurement properties. The functional data provided by the instrument could be used to enhance care and help treatment follow-up.

Orientation and position of head posture, scapula and thoracic spine in mouth-breathing children.

OBJECTIVE: Mouth-breathing is a common clinical condition among school-age children and some studies have correlated this condition with quality of life and postural alterations. Therefore, the objective of this study was to investigate the orientation and position of the scapula, thoracic spine and head posture among mouth-breathing (MB) children and nasal-breathing (NB) children. METHODS: Twenty-one male MB children and 21 male NB children between 8 and 12 years of age participated in the study. Data were obtained through a stereophotogrammetry system that uses passive markers over anatomical landmarks to capture the position of the segments. Internal rotation, upward rotation, anterior tilt, scapular elevation and abduction were measured bilaterally as well as thoracic kyphosis, forward head position and shoulder protrusion. RESULTS: The MB children showed increased scapular superior position in relation to the NB group. No statistically significant differences were found between groups regarding the angular and linear measurements of the scapula. To verify reliability, three measurements were taken for each variable in the study. The intraclass correlation coefficient (ICC) showed results above 0.8 for all the variables except for the internal rotation angle (I-Rot), below 0.5, probably due to uncertainty in the palpation of the inferior angle of the scapula. Ninety-five percent of the NB children and 58% among the MB children had been breastfed, this difference was statistically significant. There were statistically significant differences between groups regarding the domains of the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQEI) scale and body mass index, which was higher among the NB children. CONCLUSIONS: MB children increased scapular superior position in comparison to NB children due probably to the position of forward head, leading to an alteration in the positioning of the mandible. The absence of significantly difference in posture pattern between groups in the present study could attributed to height-weight development in this age, as the posture of children changes in order to adapt to new body proportions, regardless of health status. The results observed in this study demonstrate the importance of using reliable measurements in the postural assessment of MB and NB children helping physical therapists to focus their strategies during rehabilitation in more specific conditions.

Frailty Status and Gait Parameters of Older Women With Type 2 Diabetes.

OBJECTIVES: Gait decline in individuals with frailty status is associated with comorbidities, falls and reduced mobility, reflecting changes in gait. The prevalence of frailty in individuals with type 2 diabetes is higher compared to individuals without diabetes. However, the consequences of frailty status on gait in older women with diabetes are unclear. The objective of the study was to investigate gait changes in older women with diabetes who are classified as vulnerable, having 1 or more frailty conditions, or robust, having none of the conditions, according to the Fried phenotype. METHODS: Participants included 203 older women: 112 without diabetes and 91 with diabetes. The nondiabetes robust group included 59 older women: nondiabetes, vulnerable, 53; diabetes, robust, 26; and diabetes, vulnerable, 65. Gait parameters were obtained by using the GAITRite system and included velocity, cadence, step length, stance time and double-support time. Multivariate analysis was conducted followed by post hoc analysis. RESULTS: Older women with diabetes and vulnerable status used more drugs and had higher body mass indexes than the groups without diabetes who were vulnerable and robust; there was no difference between the diabetes, robust and diabetes, vulnerable groups. Falls history and fear of falling were similar in all groups. Vulnerable older women with diabetes walked with decreased velocity, cadence and step length and increased stance time compared to all groups and with increased double-support time compared to the nondiabetes robust and nondiabetes vulnerable groups. CONCLUSIONS: Gait decline in vulnerable older women with diabetes is worsened by their frailty status. Our study reinforces the importance of screening older women with diabetes for frailty status.

Efficacy of ankle-foot orthoses on gait of children with cerebral palsy: systematic review of literature.

PURPOSE: To perform a literature review evaluating the quality of current research on the influence of ankle-foot orthoses (AFOs) on gait in children with cerebral palsy (CP). METHODS: A qualitative systematic review of intervention studies including the following words/phrases in the title/abstract: children with CP, AFO, gait and inferential statistical analysis, and outcomes related to gait. Databases searched included PubMed, Cochrane Library, PEDro, OTSeeker, Lilacs, and Scielo. Level of evidence was graded using the PEDro Scale. RESULTS: Two between-group and 18 within-group studies met the inclusion criteria indicating a low level of evidence. Between-group studies each scored 4 on the PEDro Scale, and 17 within-group studies scored 3 and 1 scored 2, indicating low quality. Standard terminology for AFOs was not used and only 6 studies described functional status using appropriate instruments. CONCLUSIONS: Studies using high quality methods are still needed to support evidence-based decisions regarding the use of AFOs for this population.

The effect of adenotonsillectomy on the position of head, cervical and thoracic spine and scapular girdle of mouth breathing children.

The clinical decision for surgical treatment of children diagnosed with mouth breathing depends on the percentage of mechanical obstruction correlated with exacerbation of upper respiratory tract infections and systemic changes. The benefits of adenotonsillectomy include changes in the nasopharyngeal space, the mandibular plane and myofunctional alterations. Post-adenotonsilectomy postural benefits have not yet been described. OBJECTIVES: To investigate the kinematics of the shoulder girdle, cervical and thoracic spine in children with mouth breathing before and after adenotonsillectomy. METHODS: Forty-nine mouth breathing children (6.3 ±â€¯1.8 years) of both sexes participated in the study. The measures of thoracic kyphosis, forward head position, shoulders protrusion and abduction, elevation, anterior tilt and internal rotation of the scapula were evaluated before and after surgery. The kinematic data were obtained using the system Qualysis ProReflex®. RESULTS: There was a significant decrease in forward head position, shoulders protrusion, elevation and anterior tilt of the scapula after surgery compared to the pre-operative. CONCLUSION: One of adenotonsillectomy results is the improvement of the posture of the head and the shoulder girdle of mouth breathing children. Clinically these findings are important and will contribute to improving the quality of life of mouth breathing children.

Postural disorders in mouth breathing children: a systematic review.

BACKGROUND: Mouth breathing syndrome can cause sleep disturbances that compromise the performance of children in school. It might also cause postural abnormalities involving the head and cervical spine; however, the association between postural abnormalities and mouth breathing in children is unclear. OBJECTIVE: To assess the methodological quality of studies and determine if there is an association between mouth breathing and postural disorders in children. METHODS: Databases comprised MEDLINE, CINAHL, PEDro, LILACS, EMBASE and Cochrane Central Registrar of Controlled Trials. Searches were until March 2016 and included studies that evaluated postural disorders in children diagnosed with mouth breathing. The Downs and Black checklist was used to evaluate the quality of the evidences. RESULTS: Ten studies were included totaling 417 children from 5 to 14 years. Two studies used the New York State Postural Rating Scale, seven used photography and one used motion capture to measure posture. The methods used to analyze the data included the Postural Analysis Software (SAPO), Fisiometer, ALCimagem and routines in MATLAB program. Quality assessment resulted in low scores (<14) for all the studies. The main areas of weakness were a clear description of the participants, of the methods used to access posture, of the principal confounders and lack of power analysis. External and internal validity were also threatened by the lack of a representative sample and blinding of the participants and assessors, respectively. CONCLUSIONS: The review provides low evidence that mouth-breathing pattern in children between the ages 5-14 years is associated with postural deviations.
