Comparison of the effects of core stability and whole-body electromyostimulation exercises on kyphosis angle and core muscle endurance of inactive people with hyper kyphosis: A quasi-experimental pre-post study.

OBJECTIVE: Restoring the degree of kyphosis to be consistent with good sagittal alignment of the spine is a key concern. This study aimed to compare the effect of core stability exercises (CSE) versus whole-body electromyostimulation (WB-EMS) and a combined program (PLUS) on kyphosis angle and core muscle endurance in sedentary individuals with hyperkyphosis. DESIGN: A quasi-experimental single group pre-post study. SETTINGS: Laboratory of corrective exercise. PARTICIPANTS: seventy-five untrained men (28.9 ± 5.3 years) with thoracic hyperkyphosis. MAIN OUTCOME MEASURES: A flexible ruler was used to measure the angle of kyphosis and McGill's test was used to evaluate core stability. RESULTS: The results of the post hoc test demonstrated that the kyphosis angle was improved in the WB-EMS and PLUS groups compared to that in the CG (P < 0.05), but no significant difference was observed among the three groups(P > 0.05). In the post-test, core stability was significantly improved in CSE, WB-EMS and PLUS groups compared to that in the CG. CONCLUSIONS: The WB-EMS and PLUS protocols as new training methods seem to be effective in changing posture parameters and correcting postural deformities, including kyphosis. Therefore, these protocols along with other rehabilitation programs can be used to correct kyphosis and improve core muscle endurance.

Comparison of the effects of core stability and whole-body electromyostimulation exercises on lumbar lordosis angle and dynamic balance of sedentary people with hyperlordosis: a randomized controlled trial.

BACKGROUND: Hyperlordosis is an excessive inward curvature of the lumbar spine that affects spinal function. The aim of this study was to compare the effects of core stability exercises (CSE), Whole-Body Electromyostimulation (WB-EMS), and CSE Plus on the Lumbar lordosis angle and dynamic balance in sedentary people with hyperlordosis. METHODS: In a parallel randomized controlled trial study, seventy five untrained male adults with hyperlordosis, recruited from clinics of sports medicine and corrective exercise centers in Tehran, were randomly assigned to four groups: CSE (n = 19), WB-EMS (n = 18), CSE Plus (n = 18), and control Group (CG) (n = 20). The CSE group performed Core stability exercises, the WB-EMS group followed a Whole-body electromyostimulation combined training protocol, and the CSE Plus group engaged in a combined program protocol (CSE with the WB-EMS vest), and the control group only participated in activities of daily living. Anthropometric parameters and outcomes, including the lordosis angle and dynamic balance, were assessed before and after a six-week training program. A flexible ruler was used to measure the angle of lordosis, and the Y balance test was employed to evaluate the dynamic balance. RESULTS: The results indicated that the lordosis angle improved in both the CSE and CSE Plus groups compared to the CG in the post-test (P = 0.017, P = 0.024). However, there were no significant differences observed between the other group pairs. Additionally, a significant difference in dynamic balance was found between the CSE Plus group and the CG in the post-test (P = 0.001), while no significant differences were observed between the other group pairs. Furthermore, within-group test results demonstrated that lumbar lordosis angle and dynamic balance variables significantly improved in the post-test compared to the pre-test stage (P < 0.05). CONCLUSIONS: The two CSE and CSE Plus training protocols are effective as training methods for correcting certain parameters and physical deformities, including lumbar lordosis. Furthermore, the CSE Plus group demonstrated a positive impact on improving dynamic balance. Consequently, it is highly recommended that individuals with hyperlordosis can benefit from the exercises of the present study, especially CSE Plus exercises along with other rehabilitation exercises. TRIAL REGISTRATION: The trial was registered at Thai Clinical Trials Registry (TCTR20221004011, registration date: 04/10/2022).

The Prediction of Chronicity in Patients With Acute and Subacute Nonspecific Low Back Pain and Associated Risk Factors: A Case-Control Study.

BACKGROUND: Chronic low back pain is one of the most common musculoskeletal disorders in different countries. AIMS: This study aimed to predict the chronicity of nonspecific acute and nonspecific low back pain (LBP) and related risk factors among cases referred to physiotherapy clinics. DESIGN: A case-control and cross-sectional study. SETTINGS: Two physiotherapy centers in Tehran, Iran. PARTICIPANTS: This study included 502 patients with acute, subacute and chronic LBP. METHOD: This study included 502 patients with acute, subacute and chronic LBP. Data were obtained using the Fear-Avoidance Beliefs Questionnaire, Patient Health Questionnaire, Pain Catastrophic Scale, Tampa Scale for Kinesiophobia, Pittsburgh Sleep Quality Index, Walker's Health-Promoting Lifestyle Questionnaire, Roland Morris Disability Questionnaire, and Numerical Pain Rating Scale. Data analysis was performed by applying independent sample t test, χ2, and multiple logistic regression in SPSS software version 25. IBM Amos version 22 was used for path analysis. RESULTS: It was found that some demographic parameters (i.e., weight, BMI, job, type of occupational task performance, history of low back pain, work shift, underlying diseases and income), some cognitive parameters (i.e., fear-avoidance beliefs, kinesiophobia, catastrophic pain, and depression), some lifestyle parameters (i.e., health responsibility, physical activity, and interpersonal relationships), sleep quality and pain related disability were among the most critical risk factors in the chronicity of acute and subacute LBP (p < .05). CONCLUSIONS: Personal, psychological, and psychosocial parameters can be among the most critical predictors in the chronicity of acute and subacute nonspecific LBP. Hence, paying attention to all the mentioned factors at the beginning of patients' treatment to create a targeted treatment algorithm and prevent the conversion of acute and subacute into chronic LBP has particular importance.

The relationship between individual, physical and psychosocial risk factors with musculoskeletal disorders and related disabilities in flight security personnel.

Purpose. The purpose of this study was to investigate the relationship between individual, physical and psychosocial risk factors with musculoskeletal disorders and related disability in flight security personnel. Methods. The study was conducted among 316 employees in Iran flight security. To study the prevalence of musculoskeletal disorders, lifestyle, occupational stress, mental workload and disability, the Cornell questionnaire, Walker lifestyle questionnaire, job content questionnaire, NASA task load index and pain disability questionnaire were used, respectively. Data were analyzed using independent-sample t test, one-way analysis of variance, χ2 test and multiple logistic regression. Results. A total 68.35% of participants had musculoskeletal disorders in at least one of their body parts. There was a significant relationship between the parameters of increased age, higher work experience, high body mass index, gender and educational level and the prevalence of musculoskeletal disorders. Also, some components related to healthy lifestyle, occupational stress and mental workload had significant association with mentioned disorders (p < 0.05). Conclusion. The parameters of lifestyle, occupational stress and mental workload are among the most important risk factors for the prevalence of work-related musculoskeletal disorders and related disabilities in flight security personnel. Therefore, corrective measures through controlling individual, physical and psychosocial risk factors are necessary.

Dextrose prolotherapy versus radial extracorporeal shock wave therapy in the treatment of chronic plantar fasciitis: A randomized, controlled clinical trial.

In the recent years, prolotherapy is increasingly being used in the field of musculoskeletal medicine. However, few studies have investigated its effectiveness in plantar fasciitis (PF). The purpose of this study was to compare the effectiveness of ultrasound-guided dextrose prolotherapy with radial extracorporeal shock wave therapy (ESWT) in the treatment of chronic PF. This randomized controlled trial was conducted on 59 patients with chronic PF. Patients were randomly assigned into two groups receiving three sessions of radial ESWT (29 patients) vs. two sessions of ultrasound-guided intrafascial 2 cc dextrose 20% injection (30 patients). The following outcome measures were assessed before and then six weeks and 12 weeks after the treatments: pain intensity by visual analog scale (VAS), daily life and exercise activities by Foot and Ankle Ability Measure (FAAM), and the plantar fascia thickness by ultrasonographic imaging. The VAS and FAAM scales showed significant improvements of pain and function in both study groups 6 weeks and 12 weeks after the treatments. A significant reduction was noted for plantar fascia thickness at these intervals (all p < .05). The inter-group comparison revealed that except for the FAAM-sport subscale which favored ESWT, the interaction effects of group and time were not significant for other outcome measures. Dextrose prolotherapy has comparable efficacy to radial ESWT in reducing pain, daily-life functional limitation, and plantar fascia thickness in patients with PF. No serious adverse effects were observed in either group. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

The reliability and concurrent validity of a new iPhone® application for measuring active lumbar spine flexion and extension range of motion in patients with low back pain.

Objective: To investigate the reliability and validity of an iPhone® application (iHandy® Level) for measuring active lumbar flexion-extension range of motion (ROM) in chronic nonspecific low back pain (CNLBP) patients. Methods: Fifteen CNLBP patients were recruited. The participants stood in a relaxed position and the T12-L1 and S1-S2 spinal levels were identified through palpation and were marked on the skin. Two blinded examiners used a gravity-based inclinometer and the application in order to measure ROM. The instruments were lined up appropriately and the participants were asked to perform maximum lumbar flexion following by maximum extension. First, each examiner placed the instruments over the T12-L1 level and then over the S1-S2 level during the movements. In order to calculate flexion-extension ROM, the measurement which was obtained from T12-L1 was subtracted from S1-S2. Intraclass correlation coefficient (ICC) models (3, k) and (2, k) were used in order to determine the intrarater and inter-rater reliability, respectively. The Spearman's correlation coefficients (rs ) and Bland-Altman plots were used in order to examine the validity. Results: Fair-to-excellent intrarater (ICC = 0.39-0.89) and moderate-to-good inter-rater reliability (ICC = 0.55-0.77) were observed using the inclinometer. Moreover, poor-to-good intrarater (ICC = 0.30-70) and inter-rater (ICC = 0.13-0.70) reliability were found with the application. The Spearman's correlation coefficients demonstrated low-to-moderate associations between the measures of the two instruments (rs ≥ 0.22). The Bland-Altman plots indicated that there was a significant difference between the instruments for measuring flexion ROM. The difference was not significant for measuring extension ROM. Conclusion: The iHandy® Level application does not have sufficient validity for measuring active lumbar flexion ROM in CNLBP patients.

Psychometric Properties of the iHandy Level Smartphone Application for Measuring Lumbar Spine Range of Motion and Lordosis: A Systematic Review of the Literature.

CONTEXT: Advent of smartphones has brought a wide range of clinical measurement applications (apps) within the reach of most clinicians. The vast majority of smartphones have numerous built-in sensors such as magnetometers, accelerometers, and gyroscopes that make the phone capable of measuring joint range of motion (ROM) and detecting joint positions. The iHandy Level app is a free app which has a visual display alike with the digital inclinometer in regard to numeric size. OBJECTIVE: The purpose of this systematic review was to evaluate available evidence in the literature to assess the psychometric properties (ie, reliability and validity) of the iHandy Level app in measuring lumbar spine ROM and lordosis. METHODS: PubMed/MEDLINE, Scopus, Ovid, Google Scholar, and ScienceDirect were searched from inception to September 2018 for single-group repeated-measures studies reporting outcomes of lumbar spine ROM or lordosis in adult individuals without symptoms of low back pain (LBP) or patients with LBP. The quality of each included study was assessed using the Quality Appraisal of Reliability Studies checklist. RESULTS: A total of 4 studies with 273 participants were included. Two studies focused on measuring active lumbar spine ROM, and 2 studies evaluated lumbar spine lordosis. Three studies included asymptomatic subjects, and one study recruited patients with LBP. The results showed that the iHandy Level app has sufficient psychometric properties for measuring standing thoraco-lumbo-sacral flexion, extension, lateral flexion, isolated lumbar spine flexion ROM, and lumbar spine lordosis in asymptomatic subjects. One study reported poor concurrent validity with a bubble inclinometer (r = .19-.53), poor intrarater reliability (intraclass correlation coefficient = .19-.39), and poor to good interrater reliability (intraclass correlation coefficient = .24-.72) for the measurement of active lumbar spine ROM using the iHandy Level app in patients with LBP. CONCLUSIONS: This review provided a valuable summary of the research to date examining the psychometric properties of the iHandy Level app for measuring lumbar spine ROM and lordosis.

The impacts of rest breaks and stretching exercises on lower back pain among commercial truck drivers in Iran.

Purpose. This study aimed to determine the impacts of rest breaks and stretching exercises on lower back pain (LBP) in commercial truck drivers. Methods. This quasi-experiment was carried out on 92 truck drivers suffering from chronic LBP. Subjects were categorized into three groups (stretching exercises and rest breaks, rest breaks only and reference). Pain severity and related disability were measured at the beginning of the survey and after 6 and 12 weeks. The latter was assessed using the Oswestry low back pain disability questionnaire (OLBPDQ) and the Roland Morris questionnaire (RMQ). Results. At the end of the intervention, the mean pain scores in the three groups were 2.72 ± 1.44, 4.11 ± 0.86 and 4.90 ± 1.31 respectively (p < 0.001). The OLBPDQ scores in group 1 (stretches and resting time breaks) were significantly lower than those in group 2 (rest break) (p = 0.009). The RMQ scores showed a significant reduction in group 1 compared with the other two groups (p = 0.001). Drivers in group 2 improved more significantly than those in group 3 regarding visual analog scale pain score (p = 0.049), OLBPDQ score (p = 0.024) and RMQ score (p = 0.011). Conclusion. This study provided converging results that supplementary exercises during break periods consistently help to minimize LBP and disability.

Force Variability in the Short- and Long-Term Type 2 Diabetes Mellitus.

BACKGROUND: Force variability is related to many kinesiological and neuromuscular properties of the body. This study was conducted to evaluate the effect of type 2 diabetes mellitus (T2DM) and sex on the several fractal and entropy indices of force changing during the repetitive isokinetic exercise of knee flexion-extension. METHODS: Fifty individuals were allowed to participate in the study, and they consist of 18 patients with short-term T2DM, 12 patients with long-term T2DM, and 20 gender/body mass index/ankle imposed to brachial pressure index and physical activity index-matched healthy control (HC) individuals. Torque of knee flexion-extension was recorded for each cycle of 40 isokinetic repetitions at a velocity of 150°/s. The slope across the peak of torques and nonlinear fractal and entropy features in the time series was calculated. Two-way univariate analysis of variance was used to analyze the effect of the groups and gender on the variables. RESULTS: The slope of flexor peak torques was significantly less in the long-term T2DM than the other groups. However, the fractal features such as SD1 and 2 of Poincare plot and fractal dimension katz were significantly decreased in the T2DM groups than the HC and in the women than men. Alpha detrended fluctuation analysis and empirical hurts exponent increased in women of short-term T2DM than men. CONCLUSION: The force variability decreased in the T2DM as compared to HC and in women as compared to men. However, the randomness of force was significantly increased in women of short-term T2DM.

An Overview of the Health Services Provision in the 2017 Kermanshah Earthquake.

OBJECTIVE: Iran, in terms of disasters, is among the top 10 countries in the world. Therefore, timely coordination and provision of rescue, transport, and treatment services after disasters are of particular importance. This study aimed to investigate and provide a short report on the provision of rescue, transport, and treatment services after the 2017 earthquake in Kermanshah. METHODS: This was a review and a descriptive study conducted using the analysis of documents and news published on valid Iranian sites and reports of some service providers in 2017 after the earthquake in Kermanshah. RESULTS: The most important strengths of post-earthquake services were the military force's cooperation, people's support, sending the popular aid and donations to earthquake areas, and the tremendous national support and religious sympathy among the people. Sending the popular aid and donations was such that they resulted in the blockage of communication routes, heavy traffic on the roads, and disrupted the relief and rescue efforts process. However, the most important weaknesses in the provision of services after this earthquake were the lack of preparedness of the government systems and the lack of orderly management for appropriate assistance and relief and, therefore, there was an inappropriate distribution of popular aid and donations among the earthquake victims. CONCLUSION: Proper coordination and service delivery after unexpected events in Iran have a considerable distance to reaching the desired point. Unfortunately, similar problems had also occurred in other earthquakes such as the Bam and Rudbar earthquakes. The repetition of these problems indicates the authorities' lack of readiness and commitment to troubleshoot weaknesses in their emergency response plan. Therefore, it is necessary for government officials to have more preparedness in all related affairs and aspects. (Disaster Med Public Health Preparedness. 2019;13:691-694).

Effectiveness of Slump Stretching on Low Back Pain: A Systematic Review and Meta-analysis.

BACKGROUND: The slump test is a type of neurodynamic test that is believed to evaluate the mechanosensitivity of the neuromeningeal structures within the vertebral canal. The objective of this review was to investigate the effectiveness of slump stretching on back pain and disability in patients with low back pain (LBP). METHODS: We searched eight electronic databases (PubMed/Medline, Scopus, Ovid, CINAHL, Embase, PEDro, Google Scholar, CENTRAL). The publication language was restricted to English, and we searched the full time period available for each database, up to October 2017. Our primary outcomes were pain and disability, and the secondary outcome was range of motion (ROM). RESULTS: We identified 12 eligible studies with 515 LBP patients. All included studies reported short-term follow-up. A large effect size (standardized mean difference [SMD] = -2.15, 95% confidence interval [CI] = -3.35 to -0.95) and significant effect were determined, favoring the use of slump stretching to decrease pain in patients with LBP. In addition, large effect sizes and significant results were also found for the effect of slump stretching on disability improvement (SMD = -8.03, 95% CI = -11.59 to -4.47) in the LBP population. A qualitative synthesis of results showed that slump stretching can significantly increase straight leg raise and active knee extension ROM. CONCLUSIONS: There is very low to moderate quality of evidence that slump stretching may have positive effects on pain in people with LBP. However, the quality of evidence for the benefits of slump stretching on disability was very low. Finally, it appears that patients with nonradicular LBP may benefit most from slump stretching compared with other types of LBP.

The power features of Masseter muscle activity in tension-type and migraine without aura headache during open-close clench cycles.

INTRODUCTION: Different types of headaches and TMJ click influence the masseter muscle activity. The aim of this study was to assess the trend of energy level of the electromyography (EMG) activity of the masseter muscle during open-close clench cycles in migraine without aura (MOA) and tension-type headache (TTH) with or without TMJ click. METHODS: Twenty-five women with MOA and twenty four women with TTH participated in the study. They matched with 25 healthy subjects, in terms of class of occlusion and prevalence of temporomandibular joint (TMJ) with click. The EMG of both masseter muscles were recorded during open-close clench cycles at a rate of 80 cycles per minute for 15 seconds. The mouth opening was restricted to two centimeters by mandibular motion frame. Signal processing steps have been done on the EMG as: noise removing, smoothing, feature extraction, and statistical analyzing. The six statistical parameters of energy computed were mean, Variance, Skewness, Kurtosis, and first and second half energy over all signal energy. RESULTS: A three-way ANOVA indicated that during all the cycles, the mean of energy was more and there was a delay in showing the peak of energy in the masseter of the left side with clicked TMJ in MOA group compared to the two other groups, while this pattern occurred inversely in the side with no-clicked TMJ (P < 0.009). The variation of energy was significantly less in MOA group compared to the two other groups in the no-clicked TMJ (P < 0.003). However, the proportion of the first or second part of signal energy to all energy showed that TTH group had less energy in the first part and more energy in the second part in comparison to the two other groups (P < 0.05). CONCLUSION: The study showed different changes in the energy distribution of masseter muscle activity during cycles in MOA and TTH. MOA, in contrast to TTH, had lateralization effect on EMG and interacted with TMJ click.

Isokinetic and Electromyographic Properties of Muscular Endurance in Short and Long-Term Type 2 Diabetes.

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) are subject to progressive reduction of muscle mass and strength. The aim of this study was to assess muscle forces and electromyography (EMG) indices in short and long-term diabetes during an isokinetic exercise. METHODS: The peak torque, work, mean power frequency (MPF) and root mean square (RMS) of knee flexors and extensors during 40 isokinetic knee extension-flexion repetitions with a velocity of 150 degree/s were recorded. 18 patients with less than 10 years with T2DM and 12 patients with equal and more than 10 years of disease were compared with 20 gender, body mass index, physical activity and peripheral circulation matched healthy controls. RESULTS: The fatigue index and slope of line across the peak torque values of the knee flexor indicate that patients with long-term T2DM were significantly more resistant to fatigue in comparison with the two other groups (p<0.009). Whereas the MPF decrease during isokinetic protocol interact with grouping in the medial hamstring (p<0.042), but it was independent to groups in other muscles (p<0.0001). The increase of RMS after fatigue protocol interacted with sex for the medial hamstring and vastus lateralis (p<0.039) and interacted with group for the extensor muscles (p<0.045). DISCUSSION & CONCLUSION: It seems that long-term T2DM cause some neuromuscular adaptations to maintain knee flexor muscle performance during functional activity especially postural control.

The Isokinetic and Electromyographic Assessment of Knee Muscles Strength in the Short- and Long-Term Type 2 Diabetes.

BACKGROUND: Type 2 diabetes (T2DM) patients are subject to muscle weakness. OBJECTIVES: The aim of the study was an assessment of electromyographic (EMG) activity of knee muscles during isometric maximal voluntary contraction in the different disease durations of T2DM. METHODS: Eighteen patients with less than 10 years and twelve patients with more than 10 years of T2DM were compared with nineteen matched healthy control subjects. EMG of flexor and extensor muscles of knee concurrently with isometric maximal peak torque of knee flexion and extension at 75 degrees of knee flexion were recorded in three groups. RESULTS: Isometric maximal peak torque of extension and root mean squared (RMS) of vastus lateralis and medial hamstring in the healthy control was significantly higher than both patient groups. Whenever the maximal isometric peak flexion torque was not significantly different between groups, the mean power frequency (MPF) of flexor muscles especially medial hamstrings were higher in the short-term T2DM than healthy control groups. The two factors, gender and age, had significant effect on maximal peak torque and RMS of knee muscles. CONCLUSIONS: EMG could show the effect of T2DM, gender and age on knee muscles activity. It seems that the medial hamstring was the most sensitive muscle of knee compartment to show the effect of T2DM and difference of short and long-term T2DM in EMG study.

Sex Differences in Neuroanatomy of the Human Mirror Neuron System: Impact on Functional Recovery of Ischemic Hemiparetic Patients.

BACKGROUND: Considering the higher activity of mirror neuron system in females, they frequently have better performance in empathy, interpersonal sensitivity, and emotional recognition compared to males. OBJECTIVES: The purpose of this study was to assess whether gender difference in neuroanatomy of the human mirror neuron system has any impact on functional recovery of ischemic hemiparetic patients. PATIENTS AND METHODS: This single-blind clinical trial was conducted on 24 patients with cerebrovascular accident (CVA) in the age range of 45 - 60 years, referring at a rehabilitation center in Tehran, Iran, during 2013 - 2014. Sampling method was stratified random sampling. The subjects were assigned to 2 groups of 12 males and 12 females. Then, each group was randomly divided into 2 groups (totally 4 groups, n = 6 for each group): women watching functional movies, control women, men watching functional movies, and control men. Movies were shown to patients and then, they were evaluated by Timed Up and Go (TUG), Six-minute walk test (SMW), Barthel index (BI), and Berg balance scale (BBS). RESULTS: Comparison of all variables related to functional activities of all groups before and after watching movies revealed significant differences. The highest percentage of change and improvement was observed in groups 1 and 3 watching the functional movies (P = 0.0001). Percentage of improvement in women of groups 1 and 2 was higher than men in groups 3 and 4 (P = 0.0003). The changes in group of females watching the functional movies (group 1) were significantly greater than in other groups (P < 0.0001). CONCLUSIONS: The Sex differences in the neuroanatomy of the human mirror neuron system affect functional recovery of patients with hemiparesis. The improvement in studied women was found to be significantly greater than studied men. The results indicate a higher chance of recovery among hemiparetic women, especially those watching functional movies.

The 2003 Bam earthquake: overview of first aid and transport of victims.

INTRODUCTION: In December 2003, the residents of Bam, Iran experienced an earthquake that measured 6.6 on the Richter scale and destroyed more than 90% of the city. PROBLEM: The purpose of this study was to assess the status of the rescue, evacuation, and transportation of the casualties during the early stages following the earthquake. METHODS: A cross-sectional study of 185 casualties who were transferred to and hospitalized in the university hospital during the first week period following the earthquake was conducted. Information regarding different places of settlement after being removed from the rubble, initial medical care, and the means of transportation was obtained by reviewing medical records and interviewing the victims. RESULTS: The mean value of the duration of times taken for the first rescuers to reach the scene and remove the casualties from the rubble was 1.7 +/- 2.7 and 0.9 +/- 1.1 hours, respectively. Sixty-nine (37.7%) of the patients stayed within the area immediately surrounding their home for average times of 8 +/- 10 hours. The majority of casualties (57.6%) were transferred manually to a first place of settlement; 45.8% were taken to a second place of settlement using blankets. Of the patients studied, 159 (85.9%) did not receive any basic medical care at the first place and intravenous fluid therapy was the most common treatment provided for 24 (13%) patients at the second place of settlement. Patients received medical care at the first place of settlement for a mean time of 16.8 +/- 13.5 hours after escaping the rubble. CONCLUSIONS: These findings indicate that the emergency medical service system in Bam was destroyed and not able to respond adequately. In order to reduce the negative effects of such disasters in the future, there is an essential need for a comprehensive disaster management plan and improvement of hospital structures, healthcare facilities, and communication between the different governmental departments for better coordination and planning.
