A Qualisys motion system capture with seven cameras and a Kistler force plate were used to record kinematics and kinetics variables of walking. The forces applied on knee, hip and L5-S1 joint contact forces (JCF) were calculated by using Open-SIM software. SPSS software was used to analyze data at an alpha set point of 0.05.Result: The propulsive and second peaks of ground reaction forces applied on sound leg were significantly higher than prosthetic leg (p<0.05). Although the forces applied on hip, knee and L5-S1 joint in the sound leg were higher compared to prosthetic leg, the interaction between side and joint factor was not significant (p>0.05).Conclusion: The results of this study showed that the meaningful JCF applied on the sound leg were more than that of prosthetic leg. Insignificant increases in JCF on the sound leg during life can create cumulative forces on knee and low-back and endanger these joints at the risk of knee OA and chronic low-back pain. Balanced forces applied on sound and prosthetic leg is important, if this is the case, so indicating using a proper usage of socket pin and prosthetic feet which may have beneficial impact on sound side loads.

One of the common ways to reduce fatigue is passive recovering or using massage and cryotherapy after exercise. The present study aimed to compare the effects of massage and cryotherapy on muscles fatigue and isokinetic parameters.Methods:This study was conducted on54 healthy athletes aged 20-30 years who were randomly divided into three groups: cooling (ice therapy), massage, and control (resting). Each of the volunteers was evaluated in two sessions. The first session was to familiarize the participants with isokinetic contraction. The second session started with a brief warm up subsequently, using Biodex Isokinetic System Average Peak Torque (APTQ), Average Power (AP), and Total Work (TW) were measured. Then, the fatigue protocol was applied. Afterwards, interventions were performed for 15 minutes. After the intervention, isokinetic parameters were evaluated again. Also, perceived fatigue and Fatigue Index (FI) were recorded before and after the intervention.Results:APTQ, AP, and TW significantlyincreased in massage and cryotherapy groupsafter the intervention, while perceived fatigue and FI decreased significantly in both conditions (P<0.05). In the control group, however, no significant differences were observed in APTQ, AP, and TW before and after the intervention (P>0.05), but perceived fatigue and FI decreased significantly (P<0.05). Moreover, isokinetic variables (APTQ, AP, and TW) were higher in the massage group compared to cryotherapy and control groups (P<0.05), but such a difference was not observed between the massage and cryotherapy groups (P>0.05).Conclusion: Massage and cryotherapy could increase isokinetic parameters and decrease FI and perceived fatigue. Therefore, massage and cryotherapy have been more effective than rest as a strategy to return to normal state and no significant difference was observed between these two groups.

There are no studies have examined the effect of kinesiotape on rounded shoulder posture. Therefore the purpose of this study was to determine the effect of scapular kinesiotaping and pectoralis minor stretching exercise on forward shoulder angle in female subjects with rounded shoulder posture.Methods: Twenty female students aged between 18 to 25 years old with rounded shoulder posture participated in this study. Then, the subjects were randomly and equally assigned to two groups: the stretch group and the stretch plus kinesiotape group. Both groups were trained for doing home exercise to stretch Pectoralis minor bilaterally for two weeks. Kinesiotape group received kinesiotape on scapular area additionally. Forward shoulder angle was measured in four sessions including pre-intervention (first session), immediately after the first intervention (second session), fourth day (third session) and at the end of two weeks (fourth session). Two-way repeated measures ANOVA (4x2) was used for data analysis.Results: kinesiotape group showed significant within-group decrease in forward shoulder angle between first session with three other sessions (P≤0.05).There was no significant within-group difference in stretch group and between groups (P=0.20) forward shoulder angle-by-group interaction in measurement sessions was significantly different (P=0.02)Conclusion: scapular kinesiotaping along with pectoralis minor stretching exercise improved rounded shoulder posture in subjects of the present study. kinesiotape is suggested as a complementary treatment with immediate effects on postural correction of rounded shoulder.

Also they have reported the effects of kinesio taping (KT) on postural control, joint support, and muscle function. However, no studies have been conducted so far to assess the immediate effects of KT after local muscle fatigue on balance. Therefore, the aim of this study was to determine whether KT improves the Y-balance test scores after quadriceps fatigue.Methods: Fifty healthy male athletes (18-35 years old) participated in this quasi-experimental study and were randomly allocated to one of the two groups. The control group received only a fatigue protocol and the KT group received both quadriceps KT and the fatigue protocol. The balance of the subjects was assessed by a Y-balance test before and after the interventions.Results: The results revealed a significant decrease in Y-balance test scores after interventions in both groups. The KT group showed better scores in Y-balance test in all directions compared to the control.Conclusion: The study confirmed the positive effect of KT on balance after a fatigue protocol in athletes. We conclude that the application of KT can be an effective intervention for improving balance after induced fatigue in athletes.

Evaluation of users’ satisfaction could enhance the quality of service delivery. Objectives: This study aimed to identify the predictive value of demographic factors on users’ satisfaction with lower-limb orthoses and related services. Methods: Ninety-seven users of LLO participated in this cross-sectional study. Users’ satisfaction was evaluated with the Orthotic & Prosthetic Users’ Survey (OPUS). SPSS version 22 using linear regression test was used to identify which demographic variables explain variation in satisfaction with LLO and services. Results: According to linear regression, the variance of satisfaction with device was significantly explained by the income level and the type of orthosis (P <0.05). However, the predictive value of these variables was relatively low (Adjusted R2 = 0.118). The results also showed that the variance of satisfaction with services was significantly explained by none of the dependent demographic variables (P> 0.05) and the prediction of the independent variable by the demographic variables was very low (Adjusted R2 = 0.063). Conclusion: Orthotists should focus more on clients with low-income to acquire their satisfaction with devices and services. They also need be more careful when making long orthoses such as Knee Ankle Foot Orthosis or Hip Knee Ankle Foot Orthosis to satisfy their users.

Three cases infected by COVID-19 induced vestibular neuritis underwent vestibular evaluation and rehabilitation. They showed unilateral dysfunction in caloric and video head impulse test. A home-based vestibular rehabilitation (VR) was used for their treatment. Although the symptoms in one patient significantly improved, she still had a mild episode of vertigo. The other two patients completely recovered. As well, they had no remaining vertigo or imbalance at the end of VR. The final physical examinations were normal and the total score of Dizziness Handicap Inventory showed no handicapping. VR could be effective on the management of COVID-19 induced vestibular neuritis. So, we could expect a good recovery similar to other disorders with unilateral vestibular hypo-function. VR could be effective on the management of COVID-19 induced vestibular neuritis. So, we could expect a good recovery similar to other disorders with unilateral vestibular hypo-function.

It is one of the leading causes of disability, especially in the elderly. Intra-articular hypertonic dextrose prolotherapy is one of the therapies used for KOA. There have been some articles showing that patients receiving intra-articular normal saline as a control group of the article had improvement as well. The aim of this randomized clinical trial study was to evaluate the efficacy of intra-articular hypertonic saline in comparison with hypertonic dextrose prolotherapy in treatment of KOA. 54 patients with KOA were randomized in two groups: hypertonic dextrose (28 patients) and hypertonic saline groups (26 patients). All patients received three intra-articular injections of either hypertonic dextrose or hypertonic saline at two weeks intervals. The visual analogue pain scale (VAS), Oxford knee scale (OKS), and Western Ontario McMaster University Osteoarthritis Index (WOMAC) questionnaire were the outcome measures which were evaluated before, 2 and 4 weeks after the injections. The data were analyzed using t-test and repeated measurement tests. Both groups showed improvements in outcome measures after 2 and 4 weeks of intervention. However, no statistically significant difference was noted between the two groups. We concluded that the intra-articular injection of hypertonic dextrose and hypertonic saline are both effective in the management of KOA. Hypertonic saline can be considered as another medical agent in management of KOA. However, further studies are suggested to evaluate its long-term effects

Methods: This is a cross-sectional study. The questionnaire was translated to Persian according to WHO method. Firstly, two fluent Persian-speaking translators, translated the questionnaire from Persian to English and then three audiologists examined the questionnaire. In the last step, two bilingual translators translated the questionnaire from Persian to English and were evaluated conceptually. Finally, the Persian version of the SSQ12 questionnaire was voluntarily presented to 99 elderly people aged 22 to 52 years hearing aids users whom hearing thresholds were measured recently. For assessing reliability and validity and test-retest reliability T-test examination and Cronbach Alpha was used. Results: Persian version of SSQ12 questionnaire shown high internal consistency (assessed by Cronbach Alpha = 0.924) and high test-retest (assessed by Cronbach Alpha = 0.868) reliability. Conclusion: The ssq12 questionnaire is a comprehensive summary of the SSQ49 questionnaire. It would be one of the valid questionnaires for evaluating hearing performance improvement in hearing aids users. This study showed that the Persian version of ssq-12 questionnaire has high reliability and validity regarding Paired Sample t-test (p<0.001) and Cronbach’s alpha showed that the questionnaire has high internal consistency (Cronbach’s alpha =0.924). The reliability of test-retest after a month was obtained and the total scale result was 0.867. According to results of this study SSQ-12 can be used as other Persian translated questionnaires like GHABP, SHQ, IOI-HA for examining the effectiveness of hearing aids and their effects on limiting disabilities related to hearing loss.

Physiotherapy (exercise therapy and biofeedback) has been presented as a common treatment for the improvement of UI. Pelvic floor physiotherapy (PFPT) with weight loss (WL) may significantly improve UI in obese women. This study aimed to compare the effects of PFPT with or without WL on UI symptoms in obese women. Methods: This non-randomized clinical trial was performed and 51 middle-aged obese women with UI were recruited. Twenty-nine women in the PFPT group received 12-session PFPT. Twenty-two women in the PFPT+WL group received 12-session PFPT and nutritionist recommendations for WL. The outcome measures included anthropometric measurements, strength and endurance of pelvic floor muscles, intravaginal pressure (IVP), international consultation on incontinence questionnaire (ICIQ-SF), visual analog scale (VAS), and quality of life (QOL). All measurements were performed at baseline and after 12-session treatment. Results: The PFPT+WL group had a 4.95 kg weight loss (P <0.001). Finally, the strength and endurance of PFM, IVP, ICIQ UI-SF, VAS, and QOL were showed significant improvement in both groups (P<0.001). The ICIQ UI-SF and total I-QOL in the PFPT+WL group were significantly different from those in the PFPT group (P=0.015, P=0.033 respectively), (95% CI: 2.23- 5.10 vs. 2.85- 5.35 and 180.48- 214.67 vs. 164.13- 203.39 respectively). Conclusion: The proposed protocol of applying PFPT with WL comparison to PFPT alone leads to much significant improvement in UI severity and QOL in middle-aged obese women with UI.

There is also. The present study reviews existing studies to investigate the occurrence of hearing loss, its types and possible causes in patients with Covid-19.findings:Studies show that the risk of transient hearing loss, sensory neurosis, and sudden deafness increases following Covid-19. Upper respiratory tract infection, followed by acute otitis media, can be a major cause of transient hearing loss in people with Covid-19. Regarding the causes of sensorineural hearing loss and sudden deafness, various reasons such as direct viral damage to peripheral organs, vascular disorders, and the use of autotoxic drugs used in the treatment of the disease have been cited.Conclusion:Because persistent hearing loss has devastating effects on quality of life, early detection of hearing loss and early intervention are essential. According to the available reports, it seems that hearing loss can be one of the complications of Covid-19, but due to the lack of sufficient evidence and heterogeneity among the existing studies, this issue can still not be stated with certainty. Therefore, longitudinal studies on a larger number of patients using appropriate assessment tools are recommended.

In this paper, neural pathology of AD, relation to neuroplasticity, associations between AD and auditory and vestibular dysfunction has been reviewed. Methods In the present study, articles were reviewed between 2000 and 2021. 50 articles, mostly related to hearing and vestibular disorders in AD, were selected from a review of 200 English articles. The keywords Alzheimer's disease, neuroplasticity, auditory and vestibular rehabilitation, auditory and vestibular disorders were searched in PubMed, ScienceDirect, Scopus, ProQuest and Google Scholar databases.   Results Recent studies have shown an association between AD and auditory and vestibular function. Hearing loss can cause dementia and reduced communication skills in patients with AD. It has also been observed that some patients with AD lose their vestibular function, leading to an imbalance in the body and an increased risk of falling. It seems neuroplasticity of the brain is a good treatment for degenerative diseases such as AD, which is possible through auditory and vestibular rehabilitation.   Conclusion Hearing and vestibular evaluation in people with AD can be an effective way to identify problems related to them, so that if the disorder is observed, due to the phenomenon of neuroplasticity and the use of auditory and vestibular rehabilitation, therapists can take effective steps in improving the performance and quality of life of these patients.

As this review concentrate on the interventin of dysphagia throughout the Covid-19 pandemic, we encompassed the reference list of articles organized by this search strategy and selected those we considered relevant in keeping with our keywords. Result: 27 articles were considered for this review  among 83 articles that had been selected in the first round. There were very limited clinical or original articles with this regard. The main topics that these publishedpapers talked about includes dysphagia intervention and COVID-19 transmission risk and swallowing assessment and therapy in patients with COVID-19 by SLPs, dysphagia screening tools, kinds of swallowing treatment and sensory stimulation in patients with COVID-19, swallowing exercises and maneuvers in cases with COVID-19 by SLPs . Conclusion: As instrumental evaluation of swallowing should be narrow in the time of the COVID-19 pandemic, SLPs would be better to find different ways for appropriate management of patients with suspected dysphagia. generally, dysphagia intervention should be reserved for tele-health.

Despite the importance of clinical education, this field has more shortcomings than the other fields of education that should be improved Methods: The aim of this study was to explore the challenges of clinical education from the perspective of rehabilitation educators. Moreover, the COVID-19 outbreak has added new challenges that should be mentioned. This qualitative study was conducted through purposeful sampling. Semi-structured interviews were performed with 12 rehabilitation clinical educators of Ahvaz Jundishapur University of Medical Sciences. Data analysis was accomplished according to conventional content analysis. To prove the trustworthiness of the data, credibility, dependability, confirmability, and transferability were assessed. Results: By data analysis, 240 initial codes were extracted. They were revealed in three main categories and nine sub-categories indicating redundant challenges faced by COVID -19: restricted clinical resources (inadequate patient number and diversity, inadequate equipment, limited clinical space, inadequate manpower), the inefficient clinical education system (poor management of clinical education programs, insufficient clinical evaluation), personal and professional characteristics of the students (lack of students’ practical knowledge, lack of motivation, fear). Conclusion: The results of this study provided a deeper insight into the perceptions and experiences of rehabilitation educators about clinical education challenges. At present, the accidental and unexpected problematic event (COVID-19 pandemic) has detrimental effects in various aspects of clinical rehabilitation sciences. It is necessary to implement the changes in futuristic plans for adaptation with COVID-19.

The aim of this study was to evaluate brain atrophies in dementia patients in Medial temporal lobe (hippocampus), frontal lobe (and anterior cingulate), parietal lobe (and posterior cingulate) and insula cortex.Methods: The present study is a retrospective cross-sectional study. 54 patients with dementia were studied. Data were collected using a checklist that included age, sex, duration of disease and swallowing information, and brain atrophy findings based on MRI reports. Atherosclerotic changes of the medial temporal lobe atrophy (MTA) score, Koedam score scale and The global cortical atrophy (GCA) scale were recorded in the checklist.  The descriptive indexes of subjects applied to report the results and Chi-square test used to compare two groups.Results: The mean age of the patients was 72.01 with a standard deviation of 10.64 years, and rang of 50-95 years. 32 patients (59.3%) were male and 22 patients (40.7%) were female with hippocampal atrophy (P = 0.12), frontal lobe atrophy (P = 0.46), parietal lobe atrophy (P = 0.83) and insular cortical atrophy (P = 0.91),did not show a significant difference in patients with and without swallowing disorders. The frequency distribution of the degree of atrophy based on the site of atrophy was significant in patients with dysphagia (P = 0.033). Conclusion: In general, the results of the present study show that the rate of atrophy of the hippocampus and frontal lobe (and anterior cingulate) in dementia patients with dysphagia is higher than dementia patients without dysphagia.

Methods:  53 senior physical and occupational therapy students with an average age of 22-42 years participated in this cross-sectional study. The Nordic Musculoskeletal Questionnaire was used to evaluate work-related musculoskeletal disorders and the postural analysis was performed using Rapid Entire Body Assessment (REBA). Results: In our study, there was a high prevalence of musculoskeletal pain in the lower back, hand, neck, and shoulder regions. Approximately, 47% of the students reported lower back pain in the past 12 months, respectively. Disability in the lower back (23%) was the most common disorder in senior physical and occupational therapy students.  The results of sub-group analysis based on sex showed that the low back was the body region with the highest prevalence of pain. Also based on the BMI, the neck is highly reported for having pain. In addition, 36% of the senior students based on the REBA tool had a highly risk level for developing musculoskeletal disorders, while the prevalence of medium risk level was 49%. Conclusion: The results of the present study indicate that lower back pain was the most common musculoskeletal disorder among the senior physiotherapy and occupational therapy students. This research also showed that based on the REBA tool, 36% of the senior students had a high risk level of developing musculoskeletal disorders.

Also, it is a long-held belief that altered force sharing between vastus medialis obliquus (VMO) and vastus lateralis (VL) plays a main role in the pathophysiology of PFP. It was presumed that patients with patellofemoral pain (PFP) exhibit altered muscular activation pattern of MH and LH during functional tasks. The aim of this study was to compare the electromyography (EMG) activity of hamstrings and quadriceps in patients with PFP and healthy subjects during stair descending. Methods: Twenty-four women with PFP and 24 non-symptomatic individuals, aged 18-40 years, recruited through convenience sampling. The EMG activity of MH and LH, VMO and VL was recorded during stair descent. The main outcome measures were onset latency and amplitude of muscle activity measured relative to the moment of foot contact measured by foot switch. Results: There was statistically significant difference in the onset of hamstrings heads between groups (p=0.014). The LH activated before MH in PFP group. Normalized muscular activity was significantly reduced for VMO (p=0.002), VL (p=.045), and LH (p=0.019) in patients with PFP compared to control group. Conclusions: Difference in temporal activation patterns of LH and MH may result in lack of rotational knee stabilization and lead to an increased patellofemoral joint pressure. Earlier activation of LH rotates tibia externally, and likely produced lateral patellar tracking.

Considering the high prevalence of flat feet and cavus feet abnormalities among people and the adverse effects resulting from these complications on both the balance and function, a systematic review on the effect of various exercise programs on postural control and dynamic balance of these individuals seems to be essential. Thus, the aim of this systematic review and meta-analysis study is to examine the effect of exercise training programs on postural control and dynamic balance among individuals with flat feet and cavus feet. Method. The papers were identified through searching across eight databases of PubMed, SCOPUS, LILACS, CINAHL, CENTRAL, Web of Science, PEDro, and Google Scholar. The search period ranged from the beginning of available date up to November 2021. In addition, manual search and complete investigation of the references of papers were also performed. Results. 13 studies were included in the systematic review and meta-analysis. The results of meta-analysis indicated that the exercise programs had a significant effect on posture control (p=0.001) and dynamic balance (p=0.001) among individuals with flat feet and cavus feet. The effect size of Hedges's g of the exercise programs on postural control was 1.81 with confidence interval 95% (1.40-2.22). The effect size of Hedges's g of the exercise programs on the dynamic balance was 1.32 with 95% confidence interval (0.98-1.67). Conclusion. In the present systematic review, it was found that exercise programs had a significant effect on postural control and dynamic balance of individuals with flat feet and cavus feet abnormalities. The results of studies revealed that to better correct abnormalities and thus improve the postural control and dynamic balance further, the period of exercise program should be increased. Also, exercise programs should also focus on greater involvement of neuromuscular systems and direct effect on the central nervous system so that greater effect would be observed on improving postural control and dynamic balance.

To explore addicted individuals characters this study investigates correlation of resiliency, emotional intelligence and their locus of control. Exploring their weaknesses would help recovering or in a more global view expand prevention agenda. Methods: Fourthy opiate addicted men were recruited in this cross sectional study by convenient sampling from Shiraz Ibn-Sina hospital. Rotter, Connor-Davidson, Shrink and demographic questioners were used in this cross-sectional study. Pearson test was applied. Results: Those with lower level of resiliency experienced more relapses after recovery (p=0/006, r= -0/424). Those with more social awareness used more psychological treatments to survive (p=0/033, r=0/337). Those with more frequency of abuse per day and those who were addicted more years than others have more periods of relapses after recovery (p=0/022, r= 0/362 and p=0/042, r= 0/323, respectively). Motivation for recovery has been more external. Frequency of abuse per day was positively correlated with years of abuse (p=0/005, r= 0/433). Conclusion: Recovery centers are suggested to assess and enhance resiliency, emotional intelligence and locus of control. It can be a prevention priority to include such programs in schools. Most participants started their addiction between 20 to 25 years old because of curiosity, so Media and policy makers must play an important role in increasing social awareness by showing real detrimental consequences. Most of the participants were unemployed and in need of money even for a better treatment so it is suggested that occupational therapist establish some vocational rehabilitation during recovery programs.

The aim of this study was to find more accurate indices, which could affect decisions about spasticity treatment by investigating the relationship among neural, mechanical, functional outcomes, and clinical parameters in spastic chronic stroke patients.  Methods: In this cross sectional study, 45 spastic chronic stroke patients were included. Clinical assessments, such as spasticity evaluation, were conducted, using the Modified Modified Ashworth Scale (MMAS). Neural properties including H-reflex latency and Hmax / Mmax ratio were acquired. Also, mechanical properties including fascicle length, pennation angle, and thickness of spastic medial gastrocnemius muscle were evaluated. Functional outcomes were evaluated through Timed Up and Go (TUG) test and Timed 10-Meter Walk Test (10-m WTT). Spearman's rank correlation analysis in SPSS version 22.0 was used to find correlations between parameters. Results: There was a low negative correlation between MMAS and H-reflex latency (r= -0.320, p = 0.032). MMAS score had a low significant relationship with pennation angle (r=0.296, p= 0.049) and thickness of muscles (r=0.389, p=0.008). However, there was no significant correlation between MMAS and functional outcomes. Conclusion: Based on these findings, MMAS can partly identify changes in neural and mechanical properties of spastic muscles.

Controlling the balance is necessary to prevent physical and psychological damages. This study aimed to investigate the effect of Mulligan mobilization technique on static and dynamic balances in patients with moderate to severe knee osteoarthritis. Methods: In a randomized controlled clinical trial, 31 patients with moderate to severe knee osteoarthritis were included and then assigned randomly into two groups of treatment (16 patients) and control (15 patients). Static and dynamic balances and pain score were evaluated in these patients once before and once after 10 sessions of treatment. Independent t-test and paired t-test were used for statistical analysis. The level of statistical significance was set at p < 0.05. Results: Pain significantly decreased in both groups after intervention (P<0.001). Pain reduction in the treatment group was significantly more than that of the control group (P=0.005). A significant improvement was found in static (P=0.01) and dynamic balances (P=0.006) after performing the intervention in the treatment group. Additionally, there was a greater improvement in static (P=0.04) and dynamic balances (P=0.02) in the treatment group compared to the control group. Conclusions: The results of the present study reveal that Mulligan mobilization technique could improve balance in patient with moderate and severe knee osteoarthritis.

Therefore, this study aimed to investigate the acute effects of resistance exercise (RE) and its impact on psychological health and peak muscle contraction (PMC) in patients with CHF. Methods: This randomized controlled trial was performed between October 2019 to December 2020. Fifty-seven patients with CHF (NYHA Class II, III) underwent initial assessments for 6 minutes walking test (6MWT), psychological response to exercise and PMC. They were randomly divided into R1, R2, and control groups. The intervention consisted of performing a short aerobic exercise including 15 minutes of walking at an intensity of 50%-reserved heart rate for all three groups and additional RE with the intensity of 50%-1RM and 75%-1RM for R1 and R2 groups, respectively. Results: The results showed that there was no significant difference between groups for 6MWT, peak muscle contraction and psychological response to exercise after the intervention (P≥0.05). PMC and psychological response to exercise improved significantly in all groups, however 6MWT increased significantly just in group R2 after the intervention. PWB was related to peak muscle contraction of left knee extensors and dorsiflexors positively and PD and FATwas related to walking distance and peak muscle contraction of left knee extensors and dorsiflexors negatively.  Conclusions: Performing just one session of exercise had significant beneficial impacts on, PMC, and psychological response in patients with CHF regardless of the exercise type and RE intensty.However, walking distance (6MWT) increased significantly in group R2 (75% of 1-RM) that shows performing higher resistance exercise is both safe and lead on functional advantages in CHF patients. There was a positive relationship between PWB and 1RM and negative relationship between PD and fatigue with 1RM.
