Official Title: Activation of Hip Muscles in Runners With Patellofemoral Syndrome: Double-blind Randomized Clinical Trial
Brief Summary:
Introduction: Hip motor control deficit and neuromuscular disorders of the gluteus medius influence the mechanics of patellofemoral joints through increased dynamic knee valgus and can lead to Patellofemoral Pain Syndrome (PFPS). Mechanoreceptors can be stimulated by an elastic tape, which sends desired tactile cues via afferent improving the functional support of the musculoskeletal system.
Objective: To analyze the response to hip stabilizer muscle activation in street runners with PFPS through the application of elastic tape therapy.
Methods: The investigators evaluated street runners between the ages of 18 and 45, who run at least 5km/week and had been suffering from pain for at least 3 months. The volunteers had been assessed in relation to their measurements, experience of pain and training routine, their medius muscle (GM) and biceps femoris muscle (BF) had also been tested with surface electromyography through pre-determined performance tests. The participants of both groups wore a bandage for 6 weeks (1 per week). However for the participants of the placebo group the investigators applied a different anatomical path without tension, eliminating all the therapeutic elements. The volunteers were reassessed following the trial.
Hypothesis: Expected to observe that elastic tape therapy do result in any improvement in the activation of hip muscles and improvement of pain in street runners with patellofemoral pain syndrome.
Detailed Summary:
Will be recruited individuals 18-45 years of age, of at least running frequency 5 km/week and history of pain in the knee for at least three months in two or more of the following listed activities: up or down stairs, squatting, kneeling , jump, long time sitting or pain on palpation of the lateral side / medial patella.
Will be included individuals without cardiovascular diseases, which have not undergone surgery of the lower limbs in the last two years without back pain and without injury to the hip or knee. They will be excluded from those presenting allergy to the use of elastic bandage or who can not remain with the use of it during the stipulated period. Participants will sign an informed consent and informed, prior to the start of collections.
Data collection was developed with a electromyography (EMG) for muscle data and questionnaire with participants by a blinded examiner initially will be held. The questionnaire consists of the Visual Analogue Scale (VAS). For EMG of the gluteus medius (GM) and biceps femoris (BF), the electrodes are positioned according to the protocols of Surface Electromyography for the Non-Invasive Assessment of Muscles (SENIAM), with the reference electrode located in anterior tibial tuberosity. The application site will be prepared with abrasion and cleansing the skin with 70% alcohol and trichotomy. The maneuver of maximum voluntary isometric contraction (MVIC) will be trained and previously performed the collection, with five seconds support for normalization of data to the gluteus medius and biceps. Among the MVICs every muscle will hold a minute's rest. The muscle activity recorded during the exercises will be expressed in percentage of MVIC. After maneuvers MVIC, individuals will rest for five minutes and then immediately to start the acquisition of electromyographic data during funct
