Abstract
Purpose: This study aimed to examine the effect of Body-Weight-Supported Treadmill Training (BWSTT) exercises on functional ambulation profile in patients with paraplegic spinal cord injury.
Methods: This was a quasi experimental study with pre test and post test. The statistical population consisted of paraplegia spinal cord injured persons in Shahrekord City. Seventeen voluntary patients with paraplegic spinal cord injury (American Spinal Injury Association [ASIA] B, C classification, with the demographic data [mean±SD] of age 32.53±1.793 y, height 175.71±1.658 cm, weight 71.59±2.442 kg, and Body Mass Index [BMI] 23.18±0.828 kg/m2) selected with convenience sampling. The subjects were randomly assigned to BWSTT group (n=10) and traditional exercise group (n=7). Both groups were trained 60 min per session, 4 sessions per week for 12 weeks. BWSTT included 15 min warm up on fixed gear bike, 45 min BWSTT with 50% body weight and finally 10 min cold down. About 10% load was added each week. Traditional exercises included 15 min warm up plus 45 min stretch exercise and resistance training. SPSS 19.0 software was used to examine between groups. An independent t test was used to compare the changes between pretest and post test between BWSTT and traditional training groups.
Results: The data showed that there were significant differences between BWSTT and traditional groups with regard to changes in lower extremity motor score (P<0.001), walking index spinal cord injury (P=0.002), 6 min walking test (P=0.001), and 10 meter walking test (P=0.001).
Conclusion: BWSTT in comparison with traditional exercise can improve more motor function and quality and quantity of walking in people with paraplegic spinal cord injury (ASIA B, C classification).

Abstract
Purpose: Several studies have reported that musculoskeletal disorders and discomforts experienced by children and adolescent students are closely related to the weight of bags or backpacks carried by them. Since students are at growth and spinal development age, attention to the pressures on their bodies is important. These pressures can cause musculoskeletal problems and various growth disorders. This study aimed to investigate the prevalence of Low Back Pain (LBP) and its relation with the backpack weight among students.
Methods: This cross-sectional study with non-experimental design was conducted on 2000 elementary and secondary school students (1000 boys and 1000 girls) who were randomly selected from schools in 5 regions of Tehran City, Iran. Students with LBP for more than 6 weeks during the study or during the last 3 years at 3 intervals that each lasted for 1 week or more were listed in a group with LBP and others in a group with no LBP (the control group). The weight of their bags or backpacks was measured over a week, and the average was recorded as the weight of carrying load. The intensity of pain was measured using the Visual Analogue Scale. To examine the prevalence of LBP in students, absolute and relative frequency distribution tests, and for examining the correlation between LBP and weight of backpacks, Independent t test were employed. Furthermore, the Pearson correlation coefficient was used to determine the relationship between the weight of backpacks and the intensity of pain. In addition, logistic regression analysis was used to assess the predictability of LBP based on the backpack weight.
Results: Based on the results, 26% of students had LBP (29.6% girls, and 21.8% boys). Mean±SD scores of LBP in girl and boy students were reported as 3.4±2.8 and 2.3±5.8, respectively. According to t test results, there was a significant difference between the two groups in terms of backpack weight both in girls and boys (P<0.05). The Pearson correlation test results showed a significant correlation between the weight of backpacks and intensity of LBP among boys (r=0.26, P=0.007) and girls (r=0.31, P<0.001). Furthermore, results of logistic regression analysis indicated that the variable of backpack weight can predict LBP (B=0.52, P=0.01).
Conclusion: The weight of the bags or backpacks carried by children and adolescent students has a significant relationship with the prevalence and intensity of LBP in this age group.

Abstract
Purpose: It is essential to maintain dynamic stability during walking to perform daily tasks independently. The present study aimed at comparing the spatiotemporal parameters and the values of the vertical Ground Reaction Force (vGRF) as well as determining the time to reach them in ankle-sprain coper and healthy athletes during the stance phase of gait.
Methods: A total of 28 female university athletes were recruited in this cross-sectional study and assigned into two groups: ankle-sprain coper (n=14) and healthy control (n=14). The gait cycle analysis was then performed on a 10-m path, and the information related to the stance phase was recorded by a foot scanning device. The spatiotemporal parameters (gait line and contact time) and the values of the vGRF along with the time to reach them were subsequently obtained from each test. The repeated measures Analysis of Variance (ANOVA) was additionally used to analyze the data (P≤0.05).
Results: The study results revealed no differences between the injured and the healthy feet in the ankle-sprain coper group in any of the variables (P>0.05). As well, the spatiotemporal gait cycle parameters between the ankle-sprain coper group and the healthy controls were not significantly different (P>0.05). However, significant differences were observed between the ankle-sprain coper and healthy controls in terms of the variables of the vGRF in the mid-stance (F=5.25, P=0.03) and the time to reach the second peak of the vGRF (F=9.13, P=0.006).
Conclusion: The spatiotemporal gait parameters were not significantly different between the ankle-sprain coper and the control groups, but the vGRF in the ankle-sprain coper was greater than that in the control group. With regard to the correlation between the reduction in the vGRF and the secondary injury, it is recommended to pay much attention to this point in rehabilitation programs following the first injury in female athletes.

Abstract
Purpose: Physicians report balance disorders and fatigue as the symptoms of Multiple Sclerosis (MS) disease. The present study compares the effect of transcranial Direct Current Stimulation (tDCS) and core stability training on the balance and disability of patients with MS.
Methods: This is a pre-test, post-test experiment study. The statistical population included all patients with MS who reffered to Rofaydeh Rehabilitation Hospital in Tehran City, Iran, in the winter of 2019. A total of 30 male and female patients aged 27-70 years were selected through available and purposive sampling methods and then randomly divided into experimental and control groups (each group 15 persons). The initial measurements of the participants’ kinetic variables of postural control were carried out by the posturography device, and afterward, Kurtzke Expanded Disability Status Scale (EDSS) was employed to measure disability. The participants’ training included core stability training for 8 weeks (30-40 min, 3 sessions per week) with 20 min online cerebellar transcranial direct current stimulation, 2 sessions per week (The first and third sessions). Then, the research variables were measured again.
Results: The results demonstrated the significant influence of cerebellar tDCS on the variables of postural control equilibrium in the second sensory condition (P<0.001), third sensory condition (P<0.001), fourth sensory condition (P<0.001), fifth sensory condition (P=0.034), and combine equilibrium (P<0.001). Besides, the cerebellar current stimulation enhanced the sensory performance of the experimental group in using the vestibular system input data (P<0.001) and vision (P<0.001), but it had no significant effect on the ability to use somatosensory input (P=0.203) and vision preference (P=0.343). This research also revealed that the cerebellar current stimulation decreased EDSS in MS patients (P=0.026).
Conclusion: The cerebellar tDCS has a beneficial effect on balance, EDSS, and modified fatigue impact scale in MS patients. The study findings also indicate that the cerebellum, vestibular system, and visual system are related, and they have an impact on balance, and cerebellar stimulation can facilitate learning motor skills.

Abstract
Purpose: This study aims to examine the effect of 6 weeks of combined exercises (CE), short foot exercise (SFE), and SFE with isometric hip abduction (IHA) on dynamic balance (DB), joint position sense (JPS), and strength in women with flexible flatfoot (FF).
Methods: A total of 40 women with flexible flatfoot (FF) participated in this semi-experimental study and were randomly assigned to three groups as follows: CE (n=14), SFE (n=13), and IHA (n=13). Six weeks of exercise were split into 3 sessions under supervision and 3 sessions at home were completed by the participants. The Y balance test, goniometer, and dynamometer were used to assess DB, JPS, and strength before and after the exercises, respectively. The mixed-model repeated-measures multivariate analysis of variance statistical test was used to analyze the data with a significance level of 0.05.
Results: The results revealed that after performing the exercises, there was a significant difference in the DB in the SFE group in two posteromedial and posterolateral directions; meanwhile, in the IHA group this difference was in three directions, while in the CE group, it was in the posterolateral direction (P<0.05). After the exercises, no significant difference was observed in either group’s JPS or plantar flexors and dorsal flexors strength (P>0.05). Between the groups, there was no difference in any of the other variables (P>0.05).
Conclusion: Considering that the DB changes in the IHA group were more than in the other two groups, these exercises are suggested to improve the DB in women with FF.

Abstract
Purpose: This study aims to investigate the effects of an eight-week sensorimotor training (SMT) program with visual feedback (VF) on knee joint proprioception and alignment in women with dynamic knee valgus (DKV).
Methods: In this quasi-experimental study, 30 women with DKV were selected and randomly divided into two groups (intervention and control groups) of 15 participants each. The intervention group underwent an eight-week VF-based SMT program consisting of three sessions lasting 60 minutes each week. Meanwhile, the control group continued with their daily routine during this period. After the training, all participants’ knee joint proprioception and alignment were assessed using the single-leg squat test (SLST) and single-leg landing test (SLLT). The results were analyzed using the analysis of covariance (ANCOVA) in the IBM SPSS Statistics software, version 26, with a significance level of P<0.05.
Results: The analysis of covariance (ANCOVA) results indicated a significant improvement in proprioception (P=0.038) and knee alignment (P=0.001) in the intervention group compared to the control group.
Conclusion: The study suggests that practicing SMT with VF can enhance knee joint proprioception and alignment in women with DKV.

Abstract
Purpose: Patellofemoral pain syndrome (PFPS) is a common condition characterized by pain in the front of the knee. Patellar taping can be an effective intervention for reducing painful symptoms.
Methods: A total of 39 women with PFPS (aged 20-30 years) participated in this randomized crossover trial. The CoP oscillations during the single-leg stance test and TTS after descending the step were evaluated and recorded on three separate days under the following conditions: without tape (WT or control), with DT and with KT. This was done using a foot pressure measurement system. The data were analyzed using repeated measures analysis of variance with a significance level of P≤0.05.
Results: Comparing three different conditions demonstrated that the CoP sway, including the mediolateral and anteroposterior oscillations, sway area, path length, and average velocity of oscillations significantly decreased in the eyes-open and eyes-closed states during the DT condition as compared to the WT (P<0.05). Furthermore, the TTS significantly decreased in the DT condition compared to the WT (P<0.001) and KT (P=0.007) conditions. KT reduced CoP variables only in the EsC condition (P<0.05).
Conclusion: DT was more effective than KT and this intervention enhances postural control in women with PFPS. Given its positive effects, it is recommended that future research investigate the long-term impact of utilizing this intervention.
