Introduction: Osteoporosis is caused by a loss in the bone mass and the subsequent complications decrease quality of life (QOL) of the patients. This study is performed aiming to determine the effects of osteoporosis and thoracic kyphosis on the parameters of QOL in postmenopausal women.Materials and Methods: This was a case-control study in which 53 postmenopausal women participated according to the T-score and thoracic kyphosis and were divided into four groups. Then, QOL and also different fields were compared among the groups using the 36-Item Short Form Health Survey questionnaire (SF-36). The data analysis was performed using SPSS software.Results: According to the results, the impact of osteoporosis on total scores of QOL was not sig
ObjectiveThis study aimed to employ nonlinear dynamic approaches to assess trunk dynamic stability with speed, symmetry, and load during repetitive flexion-extension (FE) movements for individuals with and without nonspecific low back pain (NSLBP).BackgroundRepetitive trunk FE movement is a typical work-related LBP risk factor contingent on speed, symmetry, and load. Improper settings/adjustments of these control parameters could undermine the dynamic stability of the trunk, hence leading to low back injuries. The underlying stability mechanisms and associated control impairments during such dynamic movements remain elusive.MethodThirty-eight male volunteers (19 healthy, 19 NSLBP) enrolled in the current study. All participants performed re
Background: Recently, the oscillatory bar has been proposed as a new and effective rehabilitation tool in people with nonspecific low back pain (NSLBP), although its effects on muscular control in this population have not been well documented, especially in lower extremity muscles and different support surface conditions. Objective: This study aimed to evaluate and compare the effects of flexi-bar use on stable and unstable surfaces on electromyographic activity of trunk and lower extremity muscles in healthy persons and those with NSLBP.Material and Methods: 18 healthy men and 18 men with NSLBP participated in this cross-sectional study. The root mean square value of electromyographic activity was calculated in the trunk and lower extremit
Background: Aerobic exercise has been shown to decrease the functional disorders related to multiple sclerosis (MS). Nevertheless, the effect of aerobic exercise training on the cytokines and neuroprotective mediators associated with the disease activity has remained relatively unknown. Objectives: The present research was conducted to evaluate the responses of the vascular endothelial growth factor (VEGF) and tumor necrosis factor-alpha (TNF-α) to single-bout and six-week aerobic exercise training in the patients with MS. Methods: Totally, 20 subjects ((n = 10) patients with MS and (n = 10) controls) who were matched in terms of gender, weight, body mass, and age were included in the study. Participants received aerobic exercise training
BackgroundThe Central Sensitization Inventory (CSI) is a patient-reported tool to assess symptoms associated with central sensitization (CS). It consists of two parts: Part A assesses 25 somatic and emotional CS-related health symptoms, and part B asks if one has previously been diagnosed with a list of 10 Central Sensitivity Syndromes and related conditions.ObjectivesThe aim of this study was to translate and cross-culturally adapt the CSI into Persian and to evaluate its psychometric properties.DesignCross-sectional study.MethodAfter completing the Persian translation, the psychometric properties of the Persian CSI (CSI-Per) were evaluated in 256 patients with chronic pain and 46 healthy subjects.ResultsA confirmatory factor analysis conf
Aims: One of unhealthy behaviours that can be leading to musculoskeletal pain and discomfort in students is keeping inappropriate posture of the vertebra column, posture of sitting on bench or behind computer, and also improper carrying of backpacks. Therefore, the aim of this study was
Aim: Students spend a lot of time at the school in sitting. While sitting in the wrong position, they put pressure on the muscles, ligaments, lumbar joints, intervertebral discs and other muscles. The purpose of the present study is to investigate the impact of health education program on sitting behavior of female student of high school of Izeh, Ahvaz, Iran.Instrument and Method: This study is a semi-experimental (field trial) in which two secondary high schools in the Izeh, one school as the control group and one school as the intervention group, will be selected randomly. The data collection tool will include Nordic Musculoskeletal Questionnaire (NMQ) and a researcher–made questionnaire to assess knowledge, attitude and behavior of par
Aims: This study aimed to investigate the efficacy of educational intervention on sitting posture in female student studying in high school in Izeh, Iran.Instruments and Methods: Current study was performed in two schools in Izeh city of Iran. Ethical approval and informed consent was obtained from the participants. One hundred and forty six (N= 146) participants from these schools were randomly allocated to an intervention (n= 73) or control group (n= 73). The intervention included two group-based sessions. The control group received usual educational. Data collection was conducted by Nordic questionnaire and a researcher–made questionnaire. Data were analyzed by SPSS 16 software, using independent t-test and Chi-square test.Findings:The
Aims: The sitting posture and its related problems are of high importance. The current research was conducted with the aim of design and evaluation of a measurement tool for sitting situation, using validity and reliability.Instruments and Methods: In this semi-experimental (field trial) study, a number of questions about knowledge, attitude, and behavior were designed and content validity and face validity were utilized to assess the validity. Then, questionnaire was given to 10 specialists in health education, physiotherapists, and ergonomists. Moreover, Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated to determine content validity, and for reliability assessment, two criteria were used, including internal con
Background: Proprioception, or joint position sense, probably plays an important role in joint function. A number of studies have shown that proper joint position sense can decrease the risk of injuries in sports. It is not very clear how patellofemoral pain syndrome (PFPS) can affect athletes joint position sense (JPS). Regarding the importance of proper joint position sense for movement performance and injury prevention in athletes, the aim of this study was to evaluate knee JPS in athletes with PFPS and compare it with asymptomatic individuals under non-weight bearing (sitting) conditions. Methods: The study design was comparative in which 15 patients and 15 healthy athletes participated. JPS was evaluated by active and passive replicati
Introduction: According to the importance of the back extensor muscle strength in postmenopausal women, this study aimed to determine the relationship between strength and changes in the thickness of back extensor muscles during isometric contraction in healthy and osteoporotic postmenopausal women. Material and Methods: 42 volunteer postmenopausal women according to their Bone Mineral Density divided into two groups “healthy” and “osteoporosis.” Strength and thickness of the muscles were measured, respectively, using a handheld dynamometer and ultrasonography. The interclass correlation was used to evaluate the relative reliability dynamometer and ultrasonography. In addition, the Pearson’s correlation coefficient was used to ana
Background: Reconstruction surgery is one of the treatment methods after an anterior cruciate ligament (ACL) injury especially in athletes. Reconstructed ACL is associated with altered joint biomechanics, abnormal muscle strength, gait disorder and decreased athletic performance. Abnormal walking pattern has been shown to be one of the functional consequences of ACL reconstruction.Objectives: The aim of this study was to investigate the reliability of kinematic and spatiotemporal gait parameters after ACL reconstruction using Zebris ultrasound movement analysis system.Methods: A sample of convenience including 20 healthy athletes and 20 athletes 4 to 6 months after ACL reconstruction participated. Subjects walked on a treadmill for one minu
Background: Whole-Body Vibration Training (WBVT) is a novel neuromuscular training method that has been recently developed as a rehabilitation tool. The purpose of this study was to determine whether WBVT is effective on electromyographic activity of the muscles of the lower limbs in patients with knee osteoarthritis.Methods: The study was designed as a single blinded randomized clinical trial (IRCT201601171637N5), 45 patients with knee osteoarthritis were randomly assigned to three groups; WBVT (n= 15) receiving 12 sessions vibration therapy, control group (n= 15) doing two exercise in the home and placebo (n= 15) doing exercise like WBVT group on-off vibration system.
