This study aims to examine the effect of McConnell taping to patients with patellofemoral pain syndrome on the change of the muscle activity of vastus medialis and vastus lateralis during squatting. The total numbers of participants are 16 patients with pain in their knee. There are three different experiments: no-taping, placebo taping, and McConnell taping. As a result, both the muscle activi...

SETTING Outpatient rehabilitation clinic. PATIENT A 37-year-old physically active male. CASE DESCRIPTION The patient presented with anterior left knee pain, exacerbated when climbing stairs, sitting, and running. Exam showed lateral tracking patellae and palpable crepitus. One hundred fifty units of botulinum toxin A was injected into his left vastus lateralis. He underwent a 12-week home e...

[Purpose] For preventing the patellofemoral pain syndrome, this study aims to suggest a proper squat method, which presents selective muscle activity of Vastus Medialis Oblique and muscle activity ratios of Vastus Medialis Oblique/Vastus Lateralis by applying squat that is a representative weight bearing exercise method in various ways depending on the surface conditions and knee bending angles...

Electromyographic biofeedback is a therapeutic modality used along with other interventions in the treatment of pain. This article presents a brief review of the effectiveness of electromyographic biofeedback in treating musculoskeletal pain. Electromyographic biofeedback may provide pain relief for chronic musculoskeletal pain due to cumulative trauma, and may be proposed as an additional inte...

There are several pathologies related to the patellofemoral joint, in which the patellofemoral syndrome is one of the most common and challenging to treat. The patellofemoral syndrome results from a malalignment of the knee extensor mechanism. The purpose of our study was to describe and compare EMG responses of the vastus medialis and vastus lateralis muscles while walking up and down stairs a...

BACKGROUND Patellofemoral pain syndrome is a descriptive term applied to patients with nonspecific anterior knee pain, and is the most common knee problem. The pain in most patellofemoral disorders is generalized to the anterior part of the knee. One important concept in patellofemoral joint function is the quadriceps angle (Q-angle). Theoretically, a higher Q-angle increases the lateral pull o...

OBJECTIVE To compare the effects of taping techniques on clinical measures in patellofemoral pain syndrome (PFPS) patients. DESIGN Crossover experimental design. SETTING Controlled laboratory. PARTICIPANTS Twenty physically active PFPS patients. MAIN OUTCOME MEASURES Isokinetic strength and endurance, and perceived pain. RESULTS Bilateral baseline differences existed for strength (inv...
