Ultrasonography and Electromyography Activity of Abdominal Muscles in Different Abdominal Exercises: A Systematic Review

SUMMARY Objective. The aim of this study was to systematically review current literature on the effectiveness of various exercises and modifications on thickness and electrical activity of abdominal muscles using ultrasonography and electromyography in healthy adults. Methods. An electronic search was carried out on PubMed, Web of science, ProQuest, Google Scholar, Cochrane and Science Direct … Continued

Are there Differences in the Muscles Activation during Exercise for Patellofemoral Pain Patients? A Cross-Sectional Study

SUMMARY Objective. To compare the activation of the gluteus medius (GM) and tensor fasciae latae (TFL) muscles, during eleven exercises to strengthen the lateral hip region in volunteers with and without pattelofemoral pain. Methods. Twenty-four females participated in this study, the evaluation was performed through the electromyography analysis of the GM and TFL muscles during … Continued

Electromyography Linear and Non-Linear Analyzing to Evaluation of the Rest Times Adequacy between 30 Lumbar Extension Tests for Fatigue Prevention

SUMMARY Objective. This paper aims to answer the following question: “Do the endurance and rest times defined in the studies prevent the physiological fatigue and its central and peripheral aspects?”. Methods. 16 muscles activity are recorded from 14 healthy men (23-29 years) during maximum lumbar isometric extension in different postures (30 trials). The electromyography linear … Continued

Electromyographic Activity of Posterior Oblique Sling Muscles During Gait in Subjects with Chronic Non-Specific Low Back Pain versus Healthy Controls

SUMMARY Objective. To measure the surface electromyographic (EMG) activity of gluteus maxi­mus (GMax) and latissimus dorsi (LD) muscles during walking and to measure the scapular upward rotation at different ranges of shoulder abduction in subjects with chronic nonspecific low back pain (CNSLBP) versus healthy controls. Methods. Twenty-six subjects with unilateral CNSLBP with a mean age … Continued

Caffeine Decreases Neuromuscular Fatigue in the Lumbar Muscles: A Randomized Blind Study

SUMMARY Background. The purpose was to evaluate a possible ergogenic effect on postural muscles, still unknown through Biering-Sørensen’s lumbar extension test. Methods. A double-blind, controlled placebo, crossover study. 51 healthy, physically inactive male subjects (18-25 years) with average body mass (BMI 18.5-24.9 kg/m2) were recruited. The subjects received oral caffeine (6 mg/kg) and saline (0.3%) … Continued

Local, Distal, Proximal, and Contralateral Effects of Low-Load Blood Flow Restriction Training on Upper Extremity Neuromuscular Performance of Healthy Women: a Randomized Placebo-Controlled Trial Protocol

SUMMARY Introduction. Low-load blood flow restriction (BFR) training may induce positive neuromuscular adaptations, but proximal BFR effects are unclear. This study aims to investigate chronic effects of low-load resistance training (LLRT) with BFR on upper extremity neuromuscular performance of healthy women. Methods. This protocol for clinical trial will include 78 volunteers randomized into three groups of 26 participants: LLRT … Continued

Role of Posterior Layer of Thoracolumbar Fascia in Epimuscular Myofascial Force Transmission From Gluteus Maximus to Latissimus Dorsi and Lower Trapezius

SUMMARY Purpose. Posterior layer of thoracolumbar fascia (PTLF) is the part of the deep fascia of back of the trunk which connects the trunk, upper and lower limb muscles. PTLF is the major myofascial linkage where myofascial force transmission can take place between the muscles attached to it. The present study evaluates the force transmission … Continued

Impact of Structural and Physiological Changes in the Vastus Medialis Muscle Following Anterior Cruciate Ligament Injury and Reconstruction on Short Term Patient-Reported Knee Function

SUMMARY Objective. The objective of this study was to observe the structural and physiological changes in vastus medialis and its impact on short-term patient-reported knee function following anterior cruciate ligament (ACL) injury and reconstruction. Patients and methods. A prospective observational study was conducted on 16 young individuals with an ACL injury. The cross-sectional area (CSA) … Continued

Influence of Hamstring Facilitatory Taping on Knee Muscle Activation and Dynamic Balance in Patients with Anterior Cruciate Ligament Deficient Knee

SUMMARY Background. Anterior cruciate ligament (ACL) deficiency affects proprioception, motor control, and dynamic balance. Stretch or Kinesio taping is one of the techniques hypothesized to address these deficits. However, there is limited objective evidence demonstrating the use of hamstring facilitatory taping in ACL deficient population. Methods. This feasibility study with a pre/post experimental design was conducted on twenty … Continued
