Kinematics of the Lumbar Spine and Hip Joints in People with Persistent Low Back Pain during Sit to Stand and Stand to Sit Activities.

To our knowledge, no study has examined the kinematics of lumbopelvic-hip complex of individuals with chronic low back pain (CLBP) who had lumbar flexion+rotation (F+R) syndrome during sit to stand (SiToSt) and stand to sit (StToSi) activities. Thus, this study aimed to examine movement patterns of the lumbopelvic-hip complex in participants with CLBP classified into F+R syndrome subgroup. This was a cross sectional study.

Evaluation of cervical spine muscles thickness in patients with cervical vertigo and healthy controls through ultrasonography.

[Purpose] Cervical vertigo as a common complaint is associated with some musculoskeletal disorders. However, to date, ultrasonographical parameters of cervical muscles in patients with cervical vertigo have not been investigated. This study was conducted to investigate size of cervical muscles in patients with cervical vertigo compared to healthy controls.

Ultrasound echo intensity of cervical muscles in women with and without forward head posture.

: Forward head posture (FHP) is a common abnormal posture in neck disorders. FHP causes an alteration of the strength in the cervical muscles. Since both muscle quantity and quality impress the muscle strength, this study aimed to compare the echo intensity of cervical muscles (index of muscle quality) between women with and without FHP.

Effect of one session of tDCS on the severity of pain in women with chronic pelvic pain.

Aim: The present study aimed to investigate the effects of tDCS on pain score in women with Chronic Pelvic Pain (CPP).

Materials & Methods: A total of 16 women with CPP participated in the present double-blind sham-controlled cross-over study. Each participant received a 20-min 0.

Electromyographic activity of the hip and knee muscles during functional tasks in males with and without patellofemoral pain.

Background: Patellofemoral pain (PFP) is a common overuse injury in physically active individuals. It is characterized by anterior knee, retropatellar, or prepatellar pain associated with activities that increase patellofemoral joint stress such as squatting, stair ascending and descending, running, jumping, prolonged sitting, and kneeling. The etiology of PFP is believed to be multifactorial.

Aim: This study aimed to compare the prevalence of pelvic musculoskeletal dysfunctions in women with and without Chronic Pelvic Pain (CPP).

Materials &methods: A total of 84 women with and without CPP (42 in each group), participated in this cross-sectional analytical study. After collecting demographic information, clinical examinations were carried out to compare pelvic musculoskeletal dysfunctions between two groups.

The Reliability of Standing Sagittal Measurements of Spinal Curvature and Range of Motion in Older Women With and Without Hyperkyphosis Using a Skin-Surface Device.

Objective: The purpose of this study was to investigate the intrarater reliability of a skin-surface instrument (Spinal Mouse, Idiag, Voletswil, Switzerland) in measuring standing sagittal curvature and global mobility of the spine in older women with and without hyperkyphosis.

Methods: Measurements were made in 19 women with hyperkyphosis (thoracic kyphosis angle ≥50°), mean age 67 ± 5 years, and 14 women without hyperkyphosis (thoracic kyphosis angle <50°), mean age 63 ± 6 years. Sagittal thoracic and lumbar curvature and mobility of the spine were assessed with the Spinal Mouse during neutral standing, full spinal flexion, and full spinal extension.

A novel approach to spinal 3-D kinematic assessment using inertial sensors: Towards effective quantitative evaluation of low back pain in clinical settings.

This paper presents a novel approach for evaluating LBP in various settings. The proposed system uses cost-effective inertial sensors, in conjunction with pattern recognition techniques, for identifying sensitive classifiers towards discriminate identification of LB patients. 24 healthy individuals and 28 low back pain patients performed trunk motion tasks in five different directions for validation.

Altered Hip Mechanics and Patellofemoral Pain. A Review of Literature.

Patellofemoral pain (PFP) is a common knee disorder in orthopedic clinics. In the last decade, several investigations have considered the role of proximal factors in addition to local and distal factors in development of PFP. There is a hypothesis which suggests that impaired neuromuscular control and altered hip joint kinematic affect tibiofemoral and patellofemoral biomechanics.

Validity and Reliability of the Persian Version of Baecke Habitual Physical Activity Questionnaire in Healthy Subjects.

Background: Baecke Habitual Physical Activity Questionnaire (BHPAQ) has widely been employed in clinical and laboratorial studies as a tool for measuring subjects' physical activities. But, the reliability and validity of this questionnaire have not been investigated among Persian speakers.

Objectives: Therefore, the aim of the current study was examining the reliability and validity of the Persian version of the BHPAQ in healthy Persian adults.

Age-related hyperkyphosis: update of its potential causes and clinical impacts-narrative review.

The present study aims to qualitatively review the contributing factors and health implications of age-related hyperkyphosis. We conducted a narrative review of observational and cohort studies describing the risk factors and epidemiology of hyperkyphosis from 1955 to 2016 using the following key words: kyphosis, hyperkyphosis, posture, age-related hyperkyphosis, kyphotic posture, aetiology and causes. This review included 77 studies.

A new device for measuring isometric force of the craniocervical flexor and extensor muscles and its reliability.

Objective: Craniocervical (CC) muscles control posture of the CC area. Muscle imbalance at this area induces musculoskeletal disorders. The purpose of this study was to develop a device for measuring isometric force of CC flexor and extensor muscles and to evaluate its intra-rater reliability.

A reliability study of the new sensors for movement analysis (SHARIF-HMIS).

Aim: SHARIF-HMIS is a new inertial sensor designed for movement analysis. The aim of the present study was to assess the inter-tester and intra-tester reliability of some kinematic parameters in different lumbar motions making use of this sensor.

Materials And Methods: 24 healthy persons and 28 patients with low back pain participated in the current reliability study.

Comparison of isometric force of the craniocervical flexor and extensor muscles between women with and without forward head posture.

Objective: The stability of the craniocervical (CC) area is provided by CC muscles. Muscle imbalance between forces of these muscles may lead to forward head posture (FHP). FHP is one of the most prevalent abnormal postures in patients with neck pain.

Correlation between Hip Rotation Range-of-Motion Impairment and Low Back Pain. A Literature Review.

Background: Hip rotation range-of-motion (ROM) impairment has been proposed as a contributing mechanical factor in the development of low back pain (LBP) symptoms. There is a hypothesis which suggests that a limited range of hip rotation results in compensatory lumbar spine rotation. Hence, LBP may develop as the result.

Translation and validation of the Persian version of the STarT Back Screening Tool in patients with nonspecific low back pain.

Objective: To translate the STarT Back Screening Tool (SBT) into Persian and to investigate the psychometric properties of the new version in a group of patients with Non-Specific Low Back Pain (NSLBP).

Background: The STarT is a validated questionnaire used for subgrouping LBP patients at three levels of low-, medium-, and high-risk, based on the risk of chronicity. It has previously been translated and validated in different languages.

Evaluation of differences between two groups of low back pain patients with and without rotational demand activities based on hip and lumbopelvic movement patterns.
