Prevalence, comorbidities, and sociodemographic predictors of conduct disorder: the national epidemiology of Iranian children and adolescents psychiatric disorders (IRCAP).

The aim was to evaluate the lifetime prevalence of conduct disorder according to sociodemographic characteristics, determine the sociodemographic predictors of conduct disorder, and estimate the rates of comorbidities of psychiatric disorders in children and adolescents with conduct disorder by age and gender. The National Epidemiology of Iranian Children and Adolescents Psychiatric Disorders was a cross-sectional, general population-based study on 30,532 children and adolescents aged 6-18 years from all provinces of Iran, which was done using multistage cluster sampling. Iranian citizens aged 6-18 years who resided at least 1 year in each province were included, and children and adolescents with severe physical illnesses that prevented them to participate in the study were excluded. The sample weighting adjustment was used, since we had randomly selected the equal number of 1000 participants of each province from the urban and rural areas. Trained psychologists conducted diagnostic interviews with the adolescents and the children's parents using the Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). In this study, 54 children aged 6-9 years (0.58%, CI 0.47-0.77), 64 adolescents aged 10-14 years (0.57%, CI 0.47-0.77), and 117 adolescents aged 15-18 years (1.22%, CI 0.96-1.44) met the criteria of the lifetime conduct disorder. Conduct disorder was significantly more common in boys than in girls, and was significantly less prevalent among those participants whose fathers had no history of psychiatric hospitalization. Of the participants with conduct disorder, 83.4% met the criteria for at least one other psychiatric disorder. Conduct disorder had a high rate of comorbidity with oppositional defiant disorder (54.89%, CI 48.50-61.12), attention-deficit/hyperactivity disorder (32.34%, CI 26.68-38.56), tobacco use (20.43%, CI 15.77-26.04), and depressive disorders (18.30%, CI 13.88-23.74). Because of using the diagnostic instrument, we found a low total rate of prevalence for conduct disorder; however, higher rates of it were observed among boys and adolescents. Further studies are needed to explore the nature of comorbidities of conduct disorder and to consider them in a large clinical population.

Overall Effects of Risk Factors Associated with Dental Caries Indices Using the Marginalized Zero-Inflated Negative Binomial Model.

The purpose of this paper is to identify risk factors for decayed, missing, and filled permanent teeth (DMFT) in a population of 12-15-year-old schoolchildren and to apply the marginalized zero-inflated negative binomial (MZINB) model for determination and estimation of the overall effects of the risk factors. A cross-sectional survey comprising 764 students aged between 12 and 15 years was used to analyze the association between caries in children and some background characteristics in children and their parents. Information on the samples' social, behavioral, and demographic status was obtained through a series of closed questions. The incidence rate ratios (IRR) were used to associate some risk factors with caries. In the entire sample, the frequency of zero was 194 (25.4%). The result of the shared-parameter marginalized zero-inflated negative binomial (SP-MZINB) model showed that being a girl (IRR = 1.18; p value = 0.021), higher dental visits frequency (IRR = 1.20; p value <0.001), lower tooth brushing frequency (IRR = 0.91; p value = 0.019), higher flossing frequency (IRR = 1.11; p value = 0.001), and lower mothers' education (IRR = 0.89; p value = 0.042) are associated with DMFT. Our results may provide better insights of the factors associated with DMFT, and health programs should focus their efforts on healthcare services, for both preventive and curative purposes. This regression model provides an appropriate fit and meaningful interpretation to handling zero-inflated count outcomes. Also, it provides direct estimates of the effects of risk factors on the overall mean that does not require postmodeling computations.

Antecedents and consequences of workplace violence against nurses: A qualitative study.

AIMS AND OBJECTIVES: To explore Iranian nurses' perceptions of and experiences with the antecedents and consequences of workplace violence perpetrated by patients, patients' relatives, colleagues and superiors. BACKGROUND: Workplace violence against nurses is a common problem worldwide, including in Iran. Although many studies have reviewed the antecedents and consequences of workplace violence, limited information is available on this topic. An understanding of the predisposing factors for violence and the consequences of violence is essential to developing programs to prevent and manage workplace violence. DESIGN: Qualitative descriptive design. METHODS: In this qualitative study, 22 unstructured, in-depth interviews were conducted with registered nurses who had experienced workplace violence and who were selecting using purposive sampling in nine hospitals. Inductive content analysis was used to analyse the data. RESULTS: Five categories emerged as predisposing factors: unmet expectations of patients/relatives, inefficient organisational management, inappropriate professional communication, factors related to nurses and factors related to patients, patients' relatives and colleagues. Individual, familial and professional consequences were identified as outcomes of workplace violence against nurses. CONCLUSIONS: Workplace violence by patients/their relatives and colleagues/superiors is affected by various complicated factors at the individual and organisational levels. In addition to negatively affecting nurses' individual and family lives, workplace violence may lead to a lower quality of patient care and negative attitudes towards the nursing profession. RELEVANCE TO CLINICAL PRACTICE: Identifying factors, which lead to workplace violence, could help facilitate documenting and reporting such incidents as well as developing the necessary interventions to reduce them. Furthermore, native instruments must be developed to predict and monitor violence.

Human dignity and professional reputation under threat: Iranian Nurses' experiences of workplace violence.

Workplace violence against nurses is a challenging problem in both developed and developing countries. Because the concept of violence bears some cultural load, nurses' understanding is region-specific. This study explores Iranian nurses' perceptions of workplace violence. Using qualitative content analysis, 22 registered nurses underwent unstructured, in-depth interviews. The main themes of threats to human dignity and professional reputation emerged, plus four categories: physical violence, psychological violence, honor insults, and ethnic-religious insults. The term "honor insults," as a unique finding, was used instead of "sexual harassment." These findings may help to redefine workplace violence based on cultural background, design strategies for supporting nurses, and prevent and manage such violence.

Validity and reliability of Abbreviated Mental Test Score (AMTS) among older Iranian.

BACKGROUND: Cognitive impairment is common among older people and is associated with increased morbidity and mortality. The main aim of this study was to evaluate the validity of the Persian version of the Abbreviated Mental Test Score (AMTS) as a screening tool for dementia. METHODS: Data were obtained from a cross-sectional study. One hundred and one older adults who were members of Iranian Alzheimer Association and 101 of their siblings were entered into this study by convenient sampling. The Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for diagnosing dementia and the Mini-Mental State Examination were used as the study tools. The gathered data were analyzed by the Mann-Whitney U-test, the Kruskal-Wallis test, Spearman's rank correlation coefficient, and the receiver-operating characteristic. RESULTS: The AMTS could successfully differentiate the dementia group from the non-dementia group. Scores were significantly correlated with Diagnostic and Statistical Manual of Mental Disorders diagnosis for dementia and Mini-Mental State Examination scores (P < 0.001). Educational level (P < 0.001) and male sex (P = 0.015) were positively associated with AMTS, whereas (P < 0.001) was negatively associated with AMTS. Total Cronbach's α coefficient was 0.90. The scores 6 and 7 showed the optimum balance between sensitivity (99% and 94%, respectively) and specificity (85% and 86%, respectively). CONCLUSIONS: The Persian version of the AMTS is a valid cognitive assessment tool for older Iranian adults and can be used for dementia screening in Iran.

A new set of 272 pictures for psycholinguistic studies: Persian norms for name agreement, image agreement, conceptual familiarity, visual complexity, and age of acquisition.

Pictures are often used in studies on memory, perception, and language; normative data are thus needed for such visual stimuli. In the present study, we aimed to obtain normative data for a set of 272 black-and-white pictures from middle-aged and elderly Persian speakers. A total of 206 volunteers were divided into two groups: a middle-aged (40-59 years old) group and an elderly (60 years old and over) group. The groups had similar characteristics in terms of education. Norms for every picture were developed to provide measures of name agreement, image agreement, conceptual familiarity, age of acquisition, and visual complexity. The results revealed that all of these measures vary with age, except for conceptual familiarity.

Narrative discourse impairments in Persian-speaking persons with traumatic brain injury: a pilot study.

OBJECTIVE: Studies have shown the presence of narrative discourse difficulties in persons with traumatic brain injury (TBI), even in those who do not suffer from aphasia. Yet, there still exist inconsistencies between the results of different studies, in particular at the microlinguistic level. Moreover, a limited number of languages have been studied in this regard. Therefore, this study aimed at examining these skills in Persian-speaking individuals with TBI. The purpose of this pilot study was to analyse the microlinguistic and macrolinguistic skills of these individuals to determine impaired linguistic measures at different levels of narrative discourse. PARTICIPANTS AND METHODS: Fourteen non-aphasic Persian-speaking persons with TBI (9 with severe TBI and 5 with moderate TBI), aged 19-40 years (mean = 25.84, SD = 5.69), and 61 age-matched healthy adults completed a narrative task. Measures of language productivity, clause density, verbal error ratio, and cohesion ratio were calculated. Also, test-retest and inter-rater reliability coefficients were analysed. RESULTS: The TBI group was impaired in some microlinguistic and all macrolinguistic measures compared to their control peers. CONCLUSION: The results of this study suggest that multi-level narrative discourse analyses of Persian-speaking individuals with TBI may be useful for speech/language pathologists wishing to evaluate communication disorders in persons with TBI.

Designing Iranian Pre-hospital Stroke Scale.

BACKGROUND: Various studies have shown that stroke morbidity and mortality could be decreased if patients receive early diagnosis and treatment. Iranian Pre-hospital Stroke Scale (IPSS) is designed based on other prehospital stroke scales available across the world as well as experiences of emergency medicine specialists and pre-hospital emergency technicians to improve the diagnostic accuracy of the stroke scale in Iran. METHODS: Using a mixed method, the study was carried out in two main phases. In the first phase, concept elicitation was conducted based on the review of the literature. Related stroke diagnosis and usual instruments in pre-hospital emergency stroke centers were documented. The IPSS was designed based on semi- structured interviews with 35 neurologists, emergency medicine practitioners and physicians working in hospitals and emergency technicians in the pre-hospital field. In the second phase, the face and content validity, and reliability were checked. RESULTS: According to results from the first phase of this study (items generation), three domains were introduced as the most important factors in detection of early signs and symptoms of stroke. In the second phase (items reduction), the face validity of the IPSS was checked based on the comments from participants (the experts and EMS technicians). The content validity was calculated based on Lawshe index. The IPSS scale content validity index (S-CVI/Ave) was calculated as 89%. To determine the criterion validity of the instrument, the IPSS scores were compared with the final diagnosis based on results from brain CT scan in hospital. CONCLUSION: During this study we developed IPSS to be used by emergency technicians in pre-hospital field with a dichotomous items and simple and easy administration. It is recommended for future studies to apply this tool to emergency dispatch units as well as triage procedures in hospitals.

Stress level and quality of life of adolescents with idiopathic scoliosis during brace treatment.

Objectives: This study aimed to evaluate the effect of brace treatment on the stress level and quality of life (QoL) of adolescents with idiopathic scoliosis. Patients and methods: A total of 194 adolescent individuals were evaluated in two groups: the adolescent idiopathic scoliosis (AIS) group with 97 patients (20 males, 77 females; mean age: 13.9±1.8 years; range 10 to 18 years) and the control group with 97 age-and sex-matched participants (20 males, 77 females; mean age: 14.3±1.7 years; range 10 to 18 years) with no spinal deformity. The AIS group wore the Milwaukee brace or a thoracolumbosacral orthosis based on the location of the apical vertebra. All participants of the AIS group filled the Persian versions of the revised Scoliosis Research Society 22-item questionnaire (SRS-22r), the eight-item Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity, and BSSQ-Brace. The control group only answered the first 20 items (subtotal items) of the SRS-22r. The brace-related QoL and stress level were assessed based on sex, brace, and deformity types. Results: The subtotal score of the SRS-22r in the AIS group was significantly lower than the control group (p<0.001). There was a significant difference between deformity-related stress and brace-related stress (p<0.001). Regarding the type of treatment, there were no significant differences in QoL and stress level between the Milwaukee brace and thoracolumbosacral orthosis groups (p>0.05). Moreover, there was a weak correlation between the BSSQ-Brace and the self-image, mental-health scores, and the total scores of the SRS-22r (r=0.39 to 0.42, p<0.001); the low level of perceived stress was associated with a high level of perceived QoL. Conclusion: The stress due to brace treatment can decrease function/activity and self-image of adolescents with idiopathic scoliosis.

Comparison of modified Ashworth scale and Hoffmann reflex in study of spasticity.

Spasticity is one of the common complications in upper motor neuron lesions and without appropriate treatment it causes disturbances in movement pattern. Assessments of patients are effective in patient's management. Modified Ashworth scale (MAS) is one of the criteria in qualitative assessment of spasticity, and there are lots of controversies about its validity. The purpose of this study is to compare MAS with electrophysiological indices of spasticity. The spasticity of upper limb muscles in patients with hemiplegic cerebral palsy are measured and recorded by MAS. Then electrophysiological indices of Hoffmann reflex (H reflex) and ratio of maximum range of action potential of combined movement of flexor carpi radialis (FCR) for upper limb and soleus for lower limb were estimated. Data of 11 patients with age range 4 to 6 were analyzed. There is no significant correlation between degree of spasticity and electrophysiological indices.

Correlation between Sleep Disorders and Function in Children with Spastic Cerebral Palsy.

OBJECTIVES: The aim of the present study was to explain the correlation between sleep disorders and function in children with spastic cerebral palsy (4-12 year). MATERIALS & METHODS: This cross-sectional study was carried out on 62 children with spastic CP (8.98±1.46 yr) recruited from rehabilitation clinics of Tehran, Iran in 2017. The Activities Scale for Kids, The Sleep Disturbance Scale for Children and the cerebral palsy Quality of Life questionnaire for Children were utilized in this study. Data were analyzed using SPSS software. RESULTS: Children with sleep disorder and arousal disorders had lower family health, lower quality of life and lower level of independence in their activities (P< 0.05). CONCLUSION: These results emphasize on the necessity of more attention about sleep disorders and family health problems in children with cerebral palsy.

The Design and Assessment of a Multiparametric Model for the Dysphonia Severity Index for Persian-speaking Populations.

OBJECTIVES: In instrumental voice assessment, multiparametric models reflect the multidimensional nature of voice and are therefore better than models that reflect only a single dimension of voice. The Dysphonia Severity Index (DSI) is one of the most common multiparametric models. In voice assessment, race, language, and structural and physiological features affect the acoustic, aerodynamic, and voice range profile measures. Given these differences, this study was conducted to design and evaluate a multiparametric and objective model for assessing the severity of dysphonia in Persian-speaking populations. MATERIAL AND METHODS: This study examined 300 participants with several types of dysphonia (104 women and 196 men) and 100 healthy individuals (63 women and 37 men). Five acoustic parameters, three aerodynamic parameters, and seven voice range profile parameters were measured for designing the model. Perceptual evaluation was performed using the grade, roughness, breathiness, asthenia, strain scale. The logistic regression analysis was used to determine the factors affecting the DSI and each component's coefficient. RESULTS: Of the 15 parameters assessed, shimmer, vital capacity, semitone range, and voice onset time of /pa/ remained in the model with their coefficients. This section presents the DSI model for the examined population. The discriminant analysis showed that this combination corresponds to 47.8 of the perceptual assessment: DSI = 0.289 (shimmer) + 0.0001 (VC) - 0.059 (STR) - 13.278 (VOT_Pa). CONCLUSION: In this study, the DSI corresponded to the physiological, linguistic, and racial characteristics of the Persian-speaking population with or without voice disorder.

Effects of Empowerment Program on the Burden of Care in Mothers of Children with Phenylketonuria.

OBJECTIVES: Phenylketonuria (PKU) is a genetic disease of children that need a lifelong diet for its treatment. Because of the high burden of care, parents and particularly mothers are prone to mental disorders or psychiatric adverse reactions. We aimed to investigate the effect of empowerment of mothers on the burden of caring for children with PKU. MATERIALS & METHODS: This was a semi-experimental (before-after with control group) study. Overall, 50 mothers of children with PKU that were referred to Endocrine Clinic in Qods Hospital of Qazvin City, northwestern Iran in 2016, were selected and randomly divided into intervention and control groups. Data collection was made by using demographic characteristics of mothers and children and also the Zarit burden interview questionnaires. Empowerment program was delivered during nine sessions of holistic and family oriented empowerment model in the intervention group. The control group received routine services. Data were analyzed using descriptive and inferential statistics through SPSS software. RESULTS: In intervention group, the mean score of overall care burden and its dimensions in the mothers of children with PKU in post-test was significantly lower than the pre-test (41.20 ± 5.04 vs. 58.24 ± 3.96; P<0.001); but pre-test and post-test scores in the control group had no significant difference (58.4 ± 5.22 vs. 58.96 ± 4; P=0.327). In other words empowerment program was able to reduce the burden of caring in mothers. CONCLUSION: Empowerment program can reduce the burden of care in mothers of children with PKU. Thus empowerment training is necessary for this group of mothers in the form of workshops and educational pamphlets.

Prevalence of Autism and its Comorbidities and the Relationship with Maternal Psychopathology: A National Population-Based Study.

BACKGROUND: There is no clear picture regarding the prevalence rates of autism and its comorbidities among Iranian children and adolescents. The present study aimed to estimate these rates as part of a large national population-based study on epidemiology of psychiatric disorders in Iranian children and adolescents. METHODS: The total sample consisted of 31000 children and adolescents between 6 to 18 years of age. The Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Present and Life time version (K-SADS-PL) was used as the diagnostic tool. RESULTS: The prevalence of autism in the total sample is equal to 0.1% (10 per 10000), with a 2:1 male-to-female ratio. In total, 86% of people with autism had at least one comorbid condition. Intellectual disability, epilepsy, enuresis and attention deficit and hyperactivity disorder (ADHD) with prevalence rates of 70.3%, 29.7%, 27% and 21.62%, respectively, were the most prevalent comorbid conditions in people with autism. Maternal personality disorders were also shown to be associated with increasing risk of autism. CONCLUSION: The present study shows high prevalence rates for autism and its comorbid conditions among Iranian children and adolescents. It also reveals that there is a relationship between some maternal psychiatric disorders and the risk of autism.

Prevalence and Correlates of Psychiatric Disorders in a National Survey of Iranian Children and Adolescents.

Objective: Considering the impact of rapid sociocultural, political, and economical changes on societies and families, population-based surveys of mental disorders in different communities are needed to describe the magnitude of mental health problems and their disabling effects at the individual, familial, and societal levels. Method : A population-based cross sectional survey (IRCAP project) of 30 532 children and adolescents between 6 and 18 years was conducted in all provinces of Iran using a multistage cluster sampling method. Data were collected by 250 clinical psychologists trained to use the validated Persian version of the semi-structured diagnostic interview Kiddie-Schedule for Affective Disorders and Schizophrenia-PL (K-SADS-PL). Results: In this national epidemiological survey, 6209 out of 30 532 (22.31%) were diagnosed with at least one psychiatric disorder. The anxiety disorders (14.13%) and behavioral disorders (8.3%) had the highest prevalence, while eating disorders (0.13%) and psychotic symptoms (0.26%) had the lowest. The prevalence of psychiatric disorders was significantly lower in girls (OR = 0.85; 95% CI: 0.80-0.90), in those living in the rural area (OR = 0.80; 95% CI: 0.73-0.87), in those aged 15-18 years (OR = 0.92; 95% CI: 0.86-0.99), as well as that was significantly higher in those who had a parent suffering from mental disorders (OR = 1.96; 95% CI: 1.63-2.36 for mother and OR = 1.33; 95% CI: 1.07-1.66 for father) or physical illness (OR = 1.26; 95% CI: 1.17-1.35 for mother and OR = 1.19; 95% CI: 1.10-1.28 for father). Conclusion: About one fifth of Iranian children and adolescents suffer from at least one psychiatric disorder. Therefore, we should give a greater priority to promoting mental health and public health, provide more accessible services and trainings, and reduce barriers to accessing existing services.

The effect of Kangaroo Care on behavioral responses to pain of an intramuscular injection in neonates.

PURPOSE: This study aims to assess the efficacy of Kangaroo Care (KC) on behavioral responses of term neonates to the pain of an intramuscular injection. DESIGN AND METHODS: One hundred healthy term neonates were enrolled and randomly assigned to intervention and control groups. In the intervention group, the neonate was held in KC for 10 min before the injection and remained in KC for the duration of the procedure. The primary outcome measure was the cumulative Neonatal Infant Pain Scale (NIPS) score immediately after injection. RESULTS: The cumulative NIPS score immediately after injection in the intervention group was significantly lower (p<.001) than in the control group. PRACTICE IMPLICATIONS: KC given before injection seems to effectively decrease pain and should be considered for minor invasive procedures in neonates.

Temperature measurement and control system for transtibial prostheses: Functional evaluation.

The accumulation of heat inside the prosthetic socket increases skin temperature and fosters perspiration, which consequently leads to high tissue stress, friction blister, discomfort, unpleasant odor, and decreased prosthesis suspension and use. In the present study, the prototype of a temperature measurement and control (TM&C) system was designed, fabricated, and functionally evaluated in a phantom model of the transtibial prosthetic socket. The TM&C system was comprised of 12 thermistors divided equally into two groups that arranged internal and external to a prosthetic silicone liner. Its control system was programmed to select the required heating or cooling function of a thermal pump to provide thermal equilibrium based on the amount of temperature difference from a defined set temperature, or the amount of difference between the mean temperature recorded by inside and outside thermistors. A thin layer of aluminum was used for thermal conduction between the thermal pump and different sites around the silicone liner. The results showed functionality of the TM&C system for thermoregulation inside the prosthetic socket. However, enhancing the structure of this TM&C system, increasing its thermal power, and decreasing its weight and cost are main priorities before further development.

Temperature measurement and control system for transtibial prostheses: Single subject clinical evaluation.

The snug fit of a prosthetic socket over the residual limb can disturb thermal balance and put skin integrity in jeopardy by providing an unpleasant and infectious environment. The prototype of a temperature measurement and control (TM&C) system was previously introduced to resolve thermal problems related to prostheses. This study evaluates its clinical application in a setting with reversal, single subject design. The TM&C system was installed on a fabricated prosthetic socket of a man with unilateral transtibial amputation. Skin temperature of the residual limb without prosthesis at baseline and with prosthesis during rest and walking was evaluated. The thermal sense and thermal comfort of the participant were also evaluated. The results showed different skin temperature around the residual limb with a temperature decrease tendency from proximal to distal. The TM&C system decreased skin temperature rise after prosthesis wearing. The same situation occurred during walking, but the thermal power of the TM&C system was insufficient to overcome heat build-up in some regions of the residual limb. The participant reported no significant change of thermal sense and thermal comfort. Further investigations are warranted to examine thermography pattern of the residual limb, thermal sense, and thermal comfort in people with amputation.

The Relationship Between the Aerodynamic Parameters of Voice and Perceptual Evaluation in the Iranian Population With or Without Voice Disorders.

OBJECTIVES: Aerodynamic evaluations can provide useful information about the interaction between the respiratory and the phonation systems. The present study was conducted to investigate the relationship of maximum phonation time (MPT), vital capacity (VC), and phonation quotient (PQ) with perceptual evaluation in different types of dysphonia. The relationship between these parameters and the type of dysphonia was also examined. MATERIALS AND METHODS: The study participants consisted of 300 individuals with different types of dysphonia (104 women and 196 men) and 100 healthy samples (63 women and 37 men). A professional speech-language pathologist conducted the perceptual evaluation based on the G (grade) component of the GRBAS scale, which stands for grade, roughness, breathiness, asthenia, and strain. VC was measured using a spirometer and MPT using a stopwatch. PQ was calculated as the ratio of VC to MPT. RESULTS: The difference between the mean ± standard deviation of PQ, VC, and MPT were found to be significant at all the four degrees of dysphonia severity (P < 0.001). There was a significant difference in mean MPT and VC between the genders (P < 0.001), but no significant gender differences were observed in terms of the mean PQ (P = 0.346). The study participants were classified into four groups, including the organic dysphonia group, neurologic dysphonia and functional dysphonia groups, and the normal group; the study variables measured were found to be significantly different between all the four groups (P < 0.001). CONCLUSION: As MPT and PQ were correlated with the perceptual G (grade) and differentiated dysphonic from healthy individuals, clinicians are recommended to take account of them in their instrumental evaluations.

Postural Control in Deaf Children.

This cross-sectional study aimed to determine the reliability of static control evaluation with Synapsys Posturography System (SPS, Marseille, France) and to compare the static postural control of deaf children with typically developing children. This study was conducted in 2 phases on 81 children of 7 to 12 years old in Tehran schools. The first phase examined the reliability of static balance evaluation with SPS. In this phase, a total of 12 children with typical development were evaluated and then do a re-test 1 week later. In the second phase, 30 children with profound sensorineural hearing loss (SNHL) and high risk in their balance (selected from Baghcheban Schools for the Deaf) as the experimental group, and 37 children with typical development (selected randomly from 2 primary schools for girls and boys in District 12 of Tehran Department of Education) as control group were enrolled in the study. They were all placed under sensory organization test evaluation. Based on the results of intraclass correlation coefficient (ICC), the unilateral random effects model, test-retest reliability in different sensory conditions, the moderate to excellent results were obtained (ICC between 0.68 and 0.94). Also, the mean displacement of pressure center in all sensory conditions, the limits of stability (LOS) area, the overall balance scores, and scores for balance sensory ratio (except the somatosensory ratio) of children with typical development were better than the deaf peers (P˂0.05). The SPS has acceptable reliability to evaluate static posture in children between the ages of 7 and 12 years. Furthermore, deaf children as compared to children with typical development had a lower static postural control in all sensory conditions. This finding confirms the need to examine the postural control for identifying the extent of sensory deficit that has caused poor balance function, and also the need for early intervention to address the balance deficit in deaf children.
