Background: The surface electromyogra-phy (EMG) is a technique to capture and measure electrical activity and muscle action potential. It is applied to specify the production of force and to analyze muscle fatigue. The Root Mean Square (RMS) value has been used to quantify the electric signal because it reflects the physiological activity in the motor unit(More)
BACKGROUND Chronic nonspecific low back pain is a significant health condition with high prevalence worldwide and it is associated with enormous costs to society. Clinical practice guidelines show that many interventions are available to treat patients with chronic low back pain, but the vast majority of these interventions have a modest effect in reducing(More)
Study Double-blind, randomized controlled trial. Objectives Evaluate the effects of pulsed electromagnetic field (PEMF) in reducing pain, improve function and muscle strength in patients with shoulder impingement syndrome (SIS). Introduction Recent studies show that a PEMF based program has been indicated for musculoskeletal disorders. However, there are(More)
OBJECTIVE This study was designed to evaluate the short-term efficacy of low-level laser therapy (LLLT) for improving pain and function in patients with knee osteoarthritis. METHODS Forty-seven patients with knee osteoarthritis (79 knees), of both genders, participated in this randomized controlled double-blind clinical trial. They were randomly allocated(More)
OBJECTIVE To evaluate the reproducibility of the modified sphygmomanometer compared to hand dynamometer to measure muscle strength of the flexor muscles of fingers. METHODS We assessed 40 healthy volunteers of both genders, aged between 20 and 55 years, who underwent the muscle strength test in the finger flexor muscles on both hands using two instruments(More)
BACKGROUND Patellofemoral pain syndrome (PFPS) is a common musculoskeletal condition, particularly among women. Patients with PFPS usually experience weakness in the gluteal muscles, as well as pain and impaired motor control during activities of daily living. Strengthening the hip muscles is an effective way of treating this disorder. Neuromuscular(More)
The purpose of the study was to compare hip agonist-antagonist isometric strength ratios between females with patellofemoral pain (PFP) syndrome and pain-free control group. One hundred and twenty females between 15 and 40 years of age (control group: n = 60; PFP group: n = 60) participated in the study. Hip adductor, abductor, medial rotator, lateral(More)
The purpose of this study was to verify, by a systematic literature review, the effect of resisted exercise applied to the inferior limbs spastic muscles in relationship to muscular force, spasticity and functionality of hemiparetic subjects. A literature review of the Medline, Lilacs, Scielo, PEDro, PubMed and Ebsco databases was performed. The following(More)
BACKGROUND Previous studies have shown a relationship between shoulder posterior capsule tightness and shoulder pain in overhead athletes. However, this relationship has not been studied in tennis players. OBJECTIVES Assessment of the shoulder range of motion (ROM), strength and posterior capsule tightness of skilled amateur tennis players who had(More)
Previous studies have suggested that internal femur rotation can influence sagittal pelvis motion. This indicates that there may be kinematic "coupling" of these two segments. The purpose of the current study was to determine whether there is a consistent and predictable kinematic relationship between the pelvis and the femur. Sixteen healthy subjects (nine(More)
