BACKGROUND Patellofemoral pain syndrome (PFPS) is a frequent cause of anterior knee pain predominantly affecting young female patients who do not have significant chondral damage. Development of PFPS is probably multifactorial, involving various knee, hip, and foot kinematic factors. Biomechanical studies have described patellar maltracking and dynamic valgus (functional malalignment) in patien...

BACKGROUND Patellofemoral pain syndrome (PFPS) is a common clinical presentation. Various neuromuscular factors have been reported to contribute to its aetiology. STUDY DESIGN Systematic review METHODS A literature search was carried out from 1998 up to December 2007. Eligible studies were those that: (1) examined the effects of hip strengthening in subjects with PFPS; (2) examined the effe...

STUDY DESIGN A single-case study design. OBJECTIVES To examine the effect of electrical stimulation of the vastus medialis muscle on stiffness, pain and function for a patient with delayed functional progress following a lateral patellar retinacular release. BACKGROUND Five months after an arthroscopic lateral patellar retinacular release, the patient, although highly motivated, had made li...

Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral li...

OBJECTIVES To investigate the effect of rigid taping that induces mechanical displacement of the skin on pain perception. DESIGN Single group experiment design with repeated measures. METHODS Twenty-three active healthy volunteers (12 men and 11 women) participated in the study. All participants received three different taping procedures: no tape, taping with tension, and taping without ten...

BACKGROUND The objective of this study was to investigate the immediate effect on gait function when ankle balance taping is applied to amateur soccer players with lateral ankle sprain. MATERIAL AND METHODS A cross-over randomized design was used. Twenty-two soccer players with an ankle sprain underwent 3 interventions in a random order. Subjects were randomly assigned to ankle balance taping, ...

[Purpose] The age at menarche in Korean women has been declining sharply. However, for the students who are just beginning to menstruate, taking pain medication might become a long-term habit continuing until adulthood. Therefore, this study investigated whether balance taping would be more helpful than medication in relieving the pain. [Subjects and Methods] Subjects of this study included 125...

Abstract Background Current clinical guidelines recommend conservative management including non-pharmacologic therapy prior to considering surgery for knee OA. There is a paucity of trials investigating the use biomechanical device therapies on those with patellofemoral joint osteoarthritis (PFJOA). The aim was systematically review effectiveness devices (bracing, taping, and footwear) in sympt...

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...
