Non-local muscle fatigue is mediated at spinal and supraspinal levels.

The objective was to measure the corticospinal excitability and motoneuron responsiveness of the right and left Biceps Brachii (BB), and left Abductor Digiti Minimi (ADM) muscles in response to submaximal isotonic fatiguing contractions performed by the right BB muscle. With the familiarization session, ten young moderately active male subjects came to the lab on seven occasions. Three sets of 3 min seated elbow curls at 25% of one-repetition maximum (1RM) separated by a 1-min rest performed by the right BB muscle were used as the fatiguing protocol.

Effects of postural and cognitive difficulty levels on the standing of healthy young males on an unstable platform.

Standing on an unstable platform requires continuous effort of the neuro‑musculoskeletal system. The aim of the present study is to evaluate the ability to remain standing on an unstable platform at different levels of postural and cognitive difficulty. Healthy young males stood in the sagittal plane on an unstable platform supported by a pair of springs with modifiable stiffness.

Interictal levels of calcitonin gene related peptide in gingival crevicular fluid of chronic migraine patients.

Calcitonin gene related peptide (CGRP) is a mediator of neurogenic inflammation playing a major role in the pathogenesis of migraine. Increases in serum CGRP have been detected previously in migraineurs and a return to baseline values regarded as successful treatment. As gingival crevicular fluid is known to originate from the serum, the aim of this study is to measure the CGRP content of gingival crevicular fluid (GCF) in chronic migraine patients and to determine whether there is a correlation between serum and GCF values of CGRP.

Efficacy of tele-rehabilitation compared with office-based physical therapy in patients with knee osteoarthritis: A randomized clinical trial.

Introduction Knee osteoarthritis is a major cause of disability among the middle to senior age groups. Despite being effective, office-based physical therapy (OBPT) needs professional human resources and is both costly and time-consuming. We aimed to compare the efficacy of tele-rehabilitation (tele-rehab) compared with OBPT in patients with knee osteoarthritis.

Evaluation of the Relationship Between Musculoskeletal Discomforts and Occupational Stressors Among Nurses.

Background: Stress in nurses may increase the prevalence of musculoskeletal discomforts.

Aim: The aim of this study was to determine the prevalence of musculoskeletal discomforts and job stress among nurses and to investigate the association between musculoskeletal discomforts and occupational stressors.

Materials And Methods: In this cross-sectional study, 144 nurses in one of the main referral hospitals of Tehran-Iran were randomly selected and studied.

Effect of platelet-rich plasma on the healing of cutaneous defects exposed to acute to chronic wounds: a clinico-histopathologic study in rabbits.

Background: Platelet-rich plasma (PRP) contains numerous growth factors to promote wound healing and angiogenesis. The aim of this study was to gain further information about the benefits of platelet-rich-plasma for healing cutaneous acute to chronic wounds.

Methods: A total of 30 New Zealand albino rabbits (n = 15/group) were randomly assigned to two experimental groups: control group, and PRP group.

Magnetic resonance imaging investigations of position of conus medullaris in adolescent idiopathic scoliosis as a peripheral neuropathy.

Adolescent idiopathic scoliosis (AIS) is a structural 3-dimensional deformity the spine, which is occurring between 10 years of age and skeletal maturity and it mostly affects prepuberbal girls. The etiology of AIS remains unknown and seems should be multifactorial. According to the theories, there could be a shorter spinal cord or a higher location of the conus medullaris and disproportionate growth in neuro-osseous system.

Venous insufficiency after prolonged standing: Is joint hypermobility an important risk factor?

Background: Varicose veins are extremely common disease which is due to elevated superficial venous pressures. We aimed to know that if joint hypermobility causes the venous insufficiency following the prolonged standing.

Materials And Methods: This prospective cohort study conducted on the soldiers of training periods in a military base of Iran Army in Isfahan in 2013.

Three-Dimensional Porous Gelapin-Simvastatin Scaffolds Promoted Bone Defect Healing in Rabbits.

Treatment of large bone defects (LBDs) is technically demanding. Tissue engineering is an option. A bioactive graft may be produced by combining tissue scaffolds and healing promotive factors in order to accelerate bone repair.

Knee Osteoarthritis Injection Choices: Platelet- Rich Plasma (PRP) Versus Hyaluronic Acid (A one-year randomized clinical trial).

Introduction: Knee osteoarthritis (OA) is the most common articular disease. Different methods are used to alleviate the symptoms of patients with knee OA, including analgesics, physical therapy, exercise prescription, and intra-articular injections (glucocorticoids, hyaluronic acid [HA], etc). New studies have focused on modern therapeutic methods that stimulate cartilage healing process and improve the damage, including the use of platelet-rich plasma (PRP) as a complex of growth factors.

Benign joint hypermobility syndrome in soldiers; what is the effect of military training courses on associated joint instabilities?

Background: Hypermobile joints are joints with beyond normal range of motion and may be associated with joint derangements. This study aimed to evaluate the prevalence of benign joint hypermobility syndrome (BJHS) among soldiers and effect of training courses on related joint instabilities.

Materials And Methods: In a prospective cohort study on 721 soldiers of Iran Army in Isfahan in 2013 the prevalence of joint hypermobility was obtained by using Beighton criteria.

Military exercises, knee and ankle joint position sense, and injury in male conscripts: a pilot study.

Context: The high incidence of lower limb injuries associated with physical exercises in military conscripts suggests that fatigue may be a risk factor for injuries. Researchers have hypothesized that lower limb injuries may be related to altered ankle and knee joint position sense (JPS) due to fatigue.

Objective: To evaluate if military exercises could alter JPS and to examine the possible relation of JPS to future lower extremity injuries in military service.

F wave to height or limb length ratios as rational alternatives for F wave latency in clinical electrodiagnostic medicine.

Objective: To delineate the F wave latency/height (F min/He) or F wave latency/limb length (F min/L) ratio as a more useful alternative for the currently reported shortest latency in milliseconds.

Methods: One hundred and sixty-six healthy volunteers, 85 upper limbs and 84 lower limbs entered the study. Minimum F wave latencies were determined in median, ulnar, tibial and peroneal nerves.

Autologous blood versus corticosteroid local injection in the short-term treatment of lateral elbow tendinopathy: a randomized clinical trial of efficacy.

Objective: To compare local corticosteroid with autologous blood injections for the short-term treatment of lateral elbow tendinopathy.

Design: A single blind, randomized clinical trial was performed in an outpatient clinic at a university hospital. Sixty patients aged 27-64 yrs with a new episode of tennis elbow were recruited.

The effects of intensive, long-term treadmill running on reproductive hormones, hypothalamus-pituitary-testis axis, and semen quality: a randomized controlled study.

Effects of intensive exercise on hypothalamus-pituitary-testis (HPT) axis remain controversial. Our aim was to determine the effects of intensive, long-term treadmill running on reproductive hormones, HPT axis, and semen quality. A total of 286 subjects were randomly assigned to moderate-intensity exercise (approximately 60% maximal oxygen uptake (VO(2max)); group 1, n=143) and high-intensity exercise (approximately 80% VO(2max); group 2, n=143) groups.
