Abstract	Background and Aim: The purpose of this study was to investigate the effects of whole-body vibration on postural control. The literature of the past 10 years were reviewed to find evidence in the recent literature for a causal association between whole-body vibration and balance disorders, and a dose-response relationship between whole-body vibration and balance disorders. Methods: Literature search was performed on PubMed, CINAHL, ISI web of science, Scopus, and Magiran databases for literature from 2002 to 2012. Conclusion: Numerous randomized-controlled clinical trials of high to moderate quality showed similar improvements in postural control after a period of whole-body vibration. Despite the lack of definite evidence, we found a sufficient number of reasons for the use of whole-body vibration in balance disorders. Future research in this field should aim to clarify the most effective dosage of whole-body vibration.

Abstract	Introduction: The present study aimed to investigate the effects of Myofascial Release Therapy (MRT) on cardiorespiratory functions in patients with COVID-19. Materials and Methods: A total of 36 patients with COVID-19 (intervention group=20, controls=16) were included in the present study. The patients in the intervention group participated in a single session of suboccipital, anterior thoracic and sternal, anterior cervical, and diaphragm myofascial release techniques, plus respiratory physiotherapy. The controls just received respiratory physiotherapy. Before-after assessments included recording heart rate, systolic and diastolic blood pressure, respiratory rate, blood oxygen saturation, chest expansion, and breathing comfort. Results: There was a significant reduction in the heart rate and ease of breathing in the intervention group (P=0.04, P=0.02; respectively); also, the diastolic blood pressure increased significantly in the control group (P=0.02). Compared to the controls, the ease of breathing decreased significantly in the intervention group (P=0.03). Conclusion: Myofascial release techniques of the neck, thoracic, and diaphragm, along with respiratory physiotherapy, could immediately affect heart rate and ease of breathing and prevent increasing diastolic blood pressure. If a patient with COVID-19 is stable, pulmonary physiotherapists may consider using these techniques while monitoring cardiopulmonary function.

Abstract	Introduction: Many changes occur in postpartum period in the body and soul of mothers that may lead to mothers' feeling fatigue. The use of reflexology has been well established as a branch of complementary medicine in the promotion of health care, especially in the field of maternal and neonatal health. Therefore, this study was performed with aim to investigate the effect of foot reflexology on postpartum fatigue in primiparous women. Methods: This clinical trial study was performed on 70 primiparous women referred to the healthcare centers in the south of Tehran in 2018. The subjects were divided into two groups of control and reflexology. The mothers of the control group received postpartum routine care and the reflexology group received massage for 3 consecutive days for 30 minutes (15 minutes per leg). Both groups completed the fatigue assessment-visual questionnaire before and after the intervention (immediately and one week after completion). Data were analyzed by SPSS statistical software (version 21) and parametric inferential statistical tests such as analysis of variance with repeated measures and non-parametric measures (Chi-square). Also, independent t-test was used to determine the significant difference between the mean of some social demographic characteristics with the treatment outcome. p < 0.05 was considered statistically significant. Results: Demographic characteristics and severity of fatigue before the intervention were the same in both reflexology and control groups. Immediately after the intervention (p <0.001) and one week after the intervention, the severity of fatigue between the two groups of reflexology and control showed a statistically significant difference (p <0.001). Conclusion: Supportive and rehabilitation measures such as foot reflexology can be effective in reducing fatigue of primiparous mothers after normal delivery.

Abstract	Introduction: Flexibility is an essential component of muscle function, and insufficient muscle flexibility may lead to muscle injuries. Decreased hamstring flexibility is one of the frequently reported risk factors for a hamstring strain and diminished athletic performance. Stretching is a commonly used intervention for increasing muscle length. There is a lack of evidence concerning the possible effects of hamstring stretching in balance and gait biomechanics. So, this study was designed to investigate the potential effects of static hamstring stretching on the range of motion (ROM), dynamic balance, and biomechanical variables of gait in athletes with hamstring tightness. Materials and Methods: This study is a single-group, pretest-posttest clinical trial performed on semi-professional female athletes. Twelve female athletes aged 20 to 35 years with bilateral hamstring tightness received a single session of unilateral static hamstring stretching on their randomly selected side. All subjects were assessed for straight leg raise, popliteal angle (using standard goniometry), perceived hamstring tightness (using a visual analog scale). They completed single-leg standing and 15-m walking and running tasks before and immediately after the intervention. The biomechanical parameters, including gait-line length, swing duration, and stance duration in walking tasks, maximum total force and mean total force in running task, and center of pressure (COP) displacement and standard deviation during balance task were measured using OpenGo sensor insole system. The pre-post values were compared using the paired sample t-test, and the level of significance was 0.05. Results: The values for straight leg raise and popliteal angle significantly increased (P<0.05) compared with the baseline, while perceived tightness significantly decreased following stretching (P<0.001). The amplitude (P₌0.006) and standard deviation (P₌0.016) of COP displacement in the mediolateral direction during the single leg stance balance task were ...

Abstract	Introduction: Flexibility or the ability of a muscle to increase in length is an integral part of musculoskeletal characteristics and is essential in preventing musculoskeletal injuries and increasing functional levels. Hamstring muscles rupture is a common injury. One of the important factors in the occurrence of this injury is poor hamstring muscle flexibility, which because of its stiffened structure, has less ability to quickly increase in length. Some researchers have recently suggested that the dry needling technique could reduce the number of treatment sessions for hamstring muscle tightness and bring faster and more effective results. Accordingly, this study aims to investigate the effect of the application of dry needling through an acupuncture technique on hamstring muscle flexibility. Materials and Methods: The present study is a single-blinded randomized controlled trial in which 16 individuals with bilateral hamstring muscle shortness were randomly allocated into dry-needling and sham-needling groups. The sampling method was non-probability convenience. The outcome measures were the right and left active knee extension range of motion, assessed before and after the first, third, and fifth sessions of intervention. A 2-factor mixed analysis of variance was applied to determine the differences between and within the two groups. Results: Except for the group main effect, time main effect and interaction effect were statistically significant for the right and left active knee extension range of motion (P<0.001). There were differences in behavioral patterns in groups; accordingly, in the real dry-needling group, a significant difference was detected across times. However, in the sham dry-needling group, no significant difference was observed. Conclusion: The application of dry needling into motor points of hamstring muscles in individuals with bilateral hamstring muscles shortness could improve flexibility and increase the range of knee extension after 3 and 5 sessions of intervention because of the ...

Abstract	Background Pulmonary physiotherapy (PPT) is an important treatment in the management of patients with different types of pulmonary disorders. We aimed to evaluate safety and efficacy of PPT in hospitalized patients with severe COVID-19 pneumonia. Methods In this randomised, single-blind, controlled trial, we enrolled hospitalized, non-intubated patients (18 to 75 years with oxygen saturation (Spo2) in free-air breathing ≤90%) with COVID-19 pneumonia at a referral hospital. Participants were randomly assigned (1:1) to receive PPT (six sessions PPT with breathing exercises and airway clearance techniques) or basic care. The primary outcomes were venous blood O2 (pO2) and CO2 (pCO2) pressures, Spo2, and three-minute walking test (3MWT) that were assessed before and end of sixth session. Secondary outcomes included level of dyspnea, venous blood PH, one-month mortality, three-month mortality and short form-36 (SF-36) after one and three months. The assessor was blinded to the assignment. This trial is registered with ClinicalTrials.gov (NCT04357340). Findings In April-May 2020, 40 participants were randomly assigned to PPT or basic care groups. While at the end of intervention, pO2 (adjusted mean difference to baseline measure (AMD) 6.43 mmHg [95%CI 2.8, 10.07], P<0.01), Spo2 (AMD 4.43% [95%CI 2.04, 6.83], P = 0.0011), and 3MTW (AMD 91.44 m [95%CI 68.88, 113.99], P<0.01) were higher in PPT group and basic care group, pCO2 was not improved (AMD -2.1 mmHg [95%CI-6.36, 2.21], P = 0.33). Based on the logistic model adjusted to baseline Spo2, the risks of mortality were reduced 81% ([95%CI: 97% reduction to 30% increase], P = .09) and 84% ([95%CI 74% reduction to 5% increase], P = .06) at one-month and three-month, respectively. There were no significant differences in most SF-36 domains scores after one and three months. No serious adverse event was observed during PPT sessions. Conclusion Early PPT can be considered a safe and relatively effective therapeutic choice for patients with severe COVID-19.

Abstract	Introduction: The prevalence of lumbar hyperlordosis is high in young women. Considering the previous studies on the role of neuro-cognitive skills in preventing musculoskeletal injuries, the goal of the present study was to examine these skills in women with lumbar hyperlordosis. Materials and Methods: A total of 15 women with normal lumbar lordosis and 15 women with lumbar hyperlordosis participated in this study. Measurements of the visual and auditory reaction time and anticipatory skills were performed by using Speed Anticipation Reaction Time (SART) test. The Independent t-test was used to compare between two groups. Results: The distribution of all variables in both groups was normal, according to the result of Kolmogorov-Smirnov test. The results showed no significant difference between the two groups (P>0.05). Conclusion: The participants of our study had no pain, movement limitations or disability. Our study results were not consistent with the findings of previous studies in this topic. It is suggested that in the future studies the individuals with severe malalignments (that affected their lifestyle) be assessed to clarify the reason for these discrepancies among study results.

Abstract	Background: The aim of the study was to investigate the reliability and agreement of the Beta-band intermuscular coherence (Bb-IMC) as a clinical assessment tool for Non-Specific Chronic Low back pain (NS-CLBP) patients and healthy subjects by studying four phases of flexion-extension task; standing, flexion, relaxation and extension phases (F-ET). Methods: Twenty-four men with NS-CLBP and 20 healthy subjects voluntarily participated in this study. All those subjects performed three trials of F-ET while the sEMG was recorded from the lumbar erector spinal, gluteus maximus and hamstring muscles of both sides. Beta-band intermuscular coherence analysis was used to calculate the pool coherence and the pairwise coherence for all mentioned muscles. Afterward, the intra-class correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) for four phases of F-ET were also used to analyze the intrarater reliability and agreement of the measurements. Results: The investigation of ICC, SEM and MDC showed that the reliability was moderate to a high level of reliability for pool and pairwise coherence of Bb-IMC in all mentioned muscles for four phases of flexion-extension task in NS-CLBP patients and healthy subjects. Yet, the agreement was low because the measurement error was relatively large. Conclusion: Up until now, no studies have used the Bb-IMC method to study Low back pain which are carried out in our study to check the reliability of this new method. Our findings revealed that pool and pairwise coherence obtained during F-ET are moderate to a high level of reliability for using Bb-IMC and could be considered as a tool for the NS-CLBP patients’ assessment. Although the small sample size investigated, in clinical practice the using this measure to conclude the interaction of corticospinal in NS-CLBP and healthy subjects should help to improve the analysis. This requires including larger sample sizes in addition to studying other circumstances and functional movements such as ...
