Intellectual disability is defined as a significantly reduced ability to perceive new or complex information and to learn and apply new skills (intelligence impairment). Studies have shown several limitations in the mobility of people with intellectual disabilities, often due to the high prevalence of balance disorders in these individuals. Therefore, their balance is not as stable as that of normal people and they often experience a high risk of falling and physical, psychological and social injuries. Weak balance and frequent falls cause fear of falling and ultimately affect a person's quality of life, which reduces a person's independence and increases the ability to depend on others for daily activities. It reduces social interactions and the ability to control the life of the disabled person. Therefore, it is necessary to examine the factors that may increase the quality of life in this group. This study aimed to investigate the effect of functional balance, cognitive functions and the risk of fall on the quality of life in people with intellectual disabilities.

The present research was a descriptive–analytical study of correlational type conducted in 2021. The statistical population of the research comprised adults with intellectual disabilities aged 18–55 years. They belonged to the mild, moderate, or severe classification of disabilities and lived in the cities of Ardabil, Tabriz and Urmia, Iran. The statistical sample of this study included 61 adults with intellectual disabilities with a mean age of 34.31 years in Ardabil, Tabriz, and Urmia. They were selected by convenience sampling method. The data of this study were collected by the World Health Organization Quality of Life–BREF (WHOQOL– BREF) (WHO, 1996), the Prudhoe Cognitive Function Test (PCFT) (Kay et al., 2003), The Johns Hopkins Fall Risk Assessment Tool (JHFRAT) (Poe et al., 2007), and the Functional Reach Test (FRT) (Duncan and et al., 1990). To investigate the relationship between quality of life with functional balance, risk of fall and cognitive functions, the Pearson correlation method was used. To understand the contribution of each dimension to predict quality of life, the regression model was used for independent variable of functional balance.

The results showed a significant relationship between the variables of quality of life with functional balance (r=0.296, p=0.021). Also, 8.9% of changes on quality of life in people with intellectual disability are explained through functional balance.

According to the results, there is a positive and significant relationship between quality of life and functional balance. Also, it is possible to predict the quality of life through functional balance. Therefore, to improve the quality of life in people with intellectual disability it is suggested that counselors and therapists include the balance system rehabilitation and training in daily life activities in the treatment plans.

Multiple sclerosis (MS) is a chronic neurological disorder that commonly affects individuals over the age of 20 and can impair motor control, including walking and balance disorders. Fatigue is a significant symptom among MS patients that can harm their quality of life and ability to perform daily activities. Regarding the deficiencies of posture control and the effect of fatigue on the quality of life of MS patients, the impact of fatigue caused by physical exercise on the posture control of these patients is worthy of consideration. So, this study aimed to investigate how physical exercise–induced fatigue affects MS patient's postural control.

This quasi–experimental study followed a pretest–posttest design with a control group. The statistical population comprised MS patients in Tehran City, Iran. The samples from among qualified volunteers were purposefully included in the study and were divided into control (20 people) and MS patients (18 people). The study's inclusion criteria for the study patients were as follows: individuals must have a confirmed diagnosis of MS by a qualified neurologist and fall within the age range of 20 to 50 years. Additionally, participants must have an Expanded Disability Status Scale score below 4.5, be able to stand for at least 30 seconds and walk independently for a minimum of 10 meters without the assistance of any devices. They should also be free of any cardiovascular or musculoskeletal disorders, not currently taking any medication that affects balance or fatigue, and without vision, hearing, or mental impairment. Lastly, they must possess the ability to perform active muscle contraction. The exclusion criterion was non–participation and lack of cooperation during the sessions. The indices of anteroposterior and mediolateral sway and sway area were obtained using the Kistler force ‎plate device to evaluate postural control in two stages: before and after fatigue due to physical exercise.‎ The Bruce modified fatigue protocol was used on a Sportec ‎treadmill to induce fatigue. The data analysis used descriptive statistical indicators such as mean and standard ‎deviation. In the inferential statistic, we conducted a multivariate analysis of the covariance test to ‎compare the effect of fatigue on the sway indices, anteroposterior, and mediolateral of the center of pressure (COP) in two groups: patients with MS and control. ‎The data were analyzed using SPSS software version 28, and the significance level of the tests was considered 0.05.

The results of this study showed significant differences between the control and MS patients in the displacement of COP in the anteroposterior and mediolateral directions (p<0.001) and also in the sway area (p=0.003).

Based on the study results, a tiring movement task harms the postural control of people with MS, and it seems that fatigue caused by physical exercise leads to an increase in the displacement of the COP in MS patients compared to healthy people.

Post-traumatic stress disorder (PTSD) is a chronic psychiatric disorder linked to physical and mental illnesses, impacting cognitive-motor skills and daily functioning.

This study aims to assess the influence of body mass, functional balance, and motor coordination on the quality of life among male military personnel with PTSD.

The descriptive-correlational study involved male military personnel aged 30 to 55 with PTSD from medical centers of FARAJA, SEPAH, and the Ministry of Defense, in 2021. A Convenience sample of 60 subjects participated voluntarily. Quality of life (SF-36), Berg functional balance, and tandem gait tests were utilized. Data analysis included Pearson’s correlation coefficient and multivariate linear regression.

Pearson correlation revealed significant associations between quality of life and functional balance (r=0.790), motor coordination (r=0.672) and body mass index (r=0.640). Linear regression indicated that functional balance (23%), motor coordination (10%), and body mass (10%) scores could predict quality of life in male military personnel with PTSD (P≤0.01).

Body mass index, functional balance and movement coordination motor coordination are predictive factors for quality of life of male military personnel with PTSD. Changes in body mass index affecting physical stability, balance loss posing a fear of falling, and reduced movement coordination impacting physical skill execution efficiency can significantly influence quality of life.

Most hemiplegic children experience disorders related to lower limbs such as balance. Considering the importance of balance, in order to participate in activities of daily living, it is very important to use modern neuro-rehabilitation methods such as mirror therapy to improve balance. The purpose of the present study was to determine the effectiveness of mirror therapy on the static and dynamic balance of children with hemiplegic CP aged 5 to 12 years.

This study was conducted as a double-blind, randomized clinical trial on 20 children with spastic hemiplegia aged between 5-12 years old, from June 2021 to August 2022 in Tehran, Iran. Participating children were randomly allocated into test (n=10) and control (n=10) groups. The children in the treatment group underwent 20 treatment sessions during four weeks. Each session consisted of 30 minutes of routine treatment and 15 minutes of mirror therapy for lower limbs. In the control group, sham therapy was performed instead of mirror therapy. The exercises performed in a seated position were: (1) active flexion of hip, knee, and ankle joints, (2) active knee extension plus ankle dorsiflexion, and (3) knee flexion (> 90°). Both groups were measured by the Pediatric Balance Scale to assess static balance and the Timed Up and Go test to assess dynamic balance at entry and the end of the study. SPSS version 26 software was used for statistical analysis.

Examining the results of the evaluations showed that before the treatment, the static and dynamic balance of the two groups did not differ significantly (p> 0/05), but the static and dynamic balance scores of the children in the treatment group after the four weeks mirror therapy period (five days per week) were statistically significant different from the control group (p<0/05).

According to the present study, it seems that mirror therapy as a complementary treatment can have a positive effect on improving balance (static and dynamic) in children with hemiplegic CP.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by challenges in communication and social interaction, as well as restricted and repetitive behaviors. The purpose of this research was to investigate the effects of eight weeks of corrective games on the rate of navicular bone drop, attention deficit, and both static and dynamic balance in children with flat feet who were on the autism spectrum.

In a quasi-experimental study with control group, 20 autistic boys aged 7 to 12 years with flat feet were purposefully selected and randomly divided into two groups: a corrective games group (n=10) and a control group (n=10). A caliper ruler, Conner's questionnaire, and the Bruininks-Oseretsky test were utilized to evaluate navicular drop, attention deficit, and static and dynamic balance, respectively. The corrective games were conducted for eight weeks under the supervision of a trainer. Covariance analysis and paired t-tests were employed to assess differences between and within groups.

After the corrective games, there was a significant decrease in navicular drop and in attention deficit (p<0.05). Additionally, static and dynamic balance improved significantly (p<0.05) in boys on the autism spectrum with flat feet following participation in the corrective games. In contrast, the control group showed no significant differences.

The results of this study indicate that corrective games positively impact navicular drop, attention deficit, and both static and dynamic balance, thereby improving the overall stability of autistic children with flat feet. It is recommended that trainers and occupational therapists incorporate these corrective games into their practices.

Flat feet is a common condition that affects the balance of children and adolescents. This study aimed to compare the effects of comprehensive corrective exercises and Xbox Kinect exercises on static and dynamic balance in adolescent girls between 10 and 12 years old with flat feet.

A semi-experimental pretest-posttest design was utilized. Forty girls aged 10-12 years with confirmed flat feet (arch drop > 9 mm) were purposively selected and randomly assigned to two groups: a corrective exercise group and an Xbox Kinect exercise group. The average weight, body mass index and navicular drop of the participants in the research were 37.58±3.34, 18.32±1.16, and 11.70±1.18, respectively. Participants engaged in specific exercises for their group for six weeks, three sessions per week. The BioDex Balance System SD, System115, VAC was used to measure static and dynamic balance before and after the intervention. SPSS version 21 was used for data analysis, and repeated measures analysis of variance applied to assess within and between groups changes (pre-test and post-test), with a significance level set at p≤0.05.

Corrective exercises significantly improved static balance variables, including overall index (p≤0.05), anterior-posterior index (p≤0.05), and lateral index (p≤0.05), as well as dynamic balance (p≤0.05) among participants. Xbox Kinect exercises also showed significant effectiveness in improving static balance variables, such as overall index (p≤0.05), anterior-posterior index (p≤0.05), lateral index (p≤0.05), and dynamic balance (p≤0.05). There was no significant difference between the effectiveness of corrective exercises and Xbox Kinect exercises on the static and dynamic balance of individuals with flat feet (p≥0.05).

Based on the research findings, Xbox Kinect exercises, when supplemented with corrective interventions, show promising potential in enhancing the balance issues associated with flat feet. Consequently, these interactive games possess the ability to serve as a notable alternative for conventional corrective exercises, due to their attractive and engaging characteristics.

Lower limb deformity in children with cerebral palsy (CP) is a common musculoskeletal problem and planovalgus is the most prevalent, characterized by talus median subluxation, calcaneal valgus, and supinated forefoot. According to studies, one issue in orthopedics and pathology is the accurate diagnosis and proper treatment of planovalgus deformity in children with bilateral spastic cerebral palsy, which has attracted researchers’ attention. Accordingly, the present study investigates the effect of planovalgus deformity on the motor performance and balance of these children.

This cross-sectional study employed a descriptive-analytical design. The convenient sampling method was used among children with bilateral spastic cerebral palsy, diagnosed with unilateral planovalgus, who were referred to the clinics of the University of Social Welfare and Rehabilitation Sciences (Nezam Mafi) and occupational therapy clinics from September 2022 to February 2023 in Tehran City, Iran. Meanwhile, all participants were willing to cooperate in this research. A total of 27 participants were evaluated by an occupational therapist based on the specified criteria and gross motor function classification system (GMFCS), which included the assessments of balance, muscle strength, range of motion, and pain. Data analysis was done using the SPSS software, version 16.

The results revealed a statistically significant difference between the mean range of motion of ankle dorsiflexion and knee extension between the two limbs (P<0.001). The mean muscle strength of the quadriceps and ankle plantar flexors indicated a statistically significant difference in the affected limb (P<0.001). Additionally, the mean displacement of the center of pressure of the foot also demonstrated a statistically significant difference regarding topographical involvement (P<0.001).

Planovalgus deformity is one of the most common ankle deformities, which is of great concern for children with cerebral palsy. The results obtained from the assessments of the child’s balance and motor function demonstrated the importance of assessment strategies and early interventions to achieve better rehabilitation outcomes for children with CP and planovalgus deformity.

The effect of knee frontal plane deviations on postural sway and kinematics ofgait in active male adolescentsKnee structural abnormalities can lead to changes human movement strategies and posture control. The aimof this study was to evaluate and compare gait and stability patterns in genuvarum, genuvalgum and healthysubject groups. In this study subjects were divided into three groups of 12 people based on Q-angle valuesand their postural sway were evaluated in three modes of perturbation and kinematics of their lowerextremity joints measured during gait. The results of this study showed a significant difference in staticbalance between genuvalgum group and the other two groups. In addition, in kinematic factors, the mostsignificant differences were observed between healthy and genuvalgum groups. According to the results ofthis study, people with genuvalgum have more stability and movement disorders than two other groups and itis necessary to pay attention to balance and movement programs in athletes with this disorder

Emotional divorce is a type of divorce that is not registered anywhere and is related to families who decide for reasons such as negative attitudes, false beliefs, sick mind, stress and worry, inability to meet the needs of life. They are forced to live under one roof. The present study was conducted with the aim of determining the effectiveness of emotion-oriented therapy on agreeableness and emotional balance of women with emotional divorce.

This research was conducted using a semi-experimental method and a pre-test-post-test research design with a control group. The statistical population of the research consisted of 100 women with emotional divorce in 2023 at Neday Mehrgan Counseling Center in Rasht, out of which a sample of 30 people was selected by purposive sampling and randomly in the intervention group. (15 people) and control (15 people) were placed. Emotional divorce (Gottman, 2008), emotional balance (Diener and et al 2010) and agreeableness (McCrae and et al 2005) questionnaires were used to collect data. The intervention group underwent 8 sessions of emotional therapy (Greenberg and Johnson, 1988), while the control group did not receive any training. Data were analyzed using multivariate analysis of covariance.

The results showed that emotional therapy was effective in increasing the agreeableness of women with emotional divorce (p<0.001). Also, the results showed that emotional therapy was effective in increasing the emotional balance of women with emotional divorce (p<0.001).

The findings of the present study showed that the use of emotion-oriented treatment content and instructions is useful in increasing agreeableness and emotional balance of women with emotional divorce. Therefore, the use of this therapeutic intervention is recommended.

The ankle joint is one of the most vulnerable joints in the body. It has been shown that changes in attention and sensory taping can affect the balance. Therefore, the present study aimed to investigate attention changes along with sensory taping on the balance of athletes with ankle sprains.

Twenty-two subjects (11 males, 11 females) with chronic ankle sprains were included and 22 healthy individuals were matched with the control group. To measure balance, the subjects stood on one leg on the force plate (injured leg) for eight stages with 3-minute rest intervals between them. The stages included: Standing with eyes open and closed along with easy and difficult cognitive tasks with and without taping. ANOVA four-way was used in the form of 2 × 2 × 2 × 2.

The results showed that the mean displacement of the center of pressure in the X axis and the standard deviation of the displacement of the center of pressure in the X and Y axes in two conditions of easy and difficult cognitive tasks before and after the tape had a significant difference (P<0.05). There is a significant difference between the two groups in the mean displacement of the center of pressure in the X axis, in the eyes open position on one leg with easy and difficult cognitive tasks (P<0.05). There is a significant difference between the two groups in the mean displacement of the center of pressure in the Y axis, in the eyes closed and open position on one leg with a hard cognitive task (P<0.05). However, in others, this difference was not significant (P>0.05)

In general, the results showed an improvement in the balance of people with chronic ankle sprains after taping and cognitive tasks; however, in some test modes, no significant improvement was observed.
