“…These results would seem to support the treatment as a potentially efective method in reducing lateral patellofemoral loading. While clini cal studies have shown that methods including selective electrical stimulation and biofeedback can produce appreciable results [11,[37][38][39], selective VMO strengthening through isometric and isokinetic exer cises has been widely questioned [6,7,9,10]. Neverthe less, the theoretical results of the present study suggest future research might be usefully directed towards Fig.…”

“…Wise et al (46) found that patients with patellofemoral pain were able to decrease their symptoms by selectively training to increase the vastus medialis activity. Bennett and Stauber's patients also demonstrated remarkable improvement after a regimen of quadriceps training 3 times a week (58).…”

Objective. To compare the effects of intraarticular (IA) injections of glycosaminoglycan polysulfate (GAGPS) plus basic conservative treatment with the effects of placebo injections plus conservative treatment and with the effects of conservative treatment alone in patients with chronic patellofemoral pain syndrome (PFPS) . Methods.We treated 53 patients who presented with chronic PFPS in 1 knee, according to 1 of the 3 protocols, in a prospective, randomized, double-blind study. Basic conservative treatment consisted of a 6-week program of quadriceps muscle exercise, elimination of symptom-producing activities, and oral doses of nonsteroidal antiinflammatory drugs. Physiologic saline served as placebo for injection. During the 6-week treatment period, 5 injections were given 1 week apart. Along with measurements of quadriceps strength, standardized subjective, functional, and clinical assessments

“…3,4 A number of factors have been proposed to influence patellar tracking, including bony alignment, soft tissue tightness, and muscle activity, [5][6][7] and most treatments for PFP aim to address these aspects. [8][9][10] Application of medially directed tape over the patella, as developed by McConnell, 11 is widely used to treat patellofemoral pain (PFP). McConnell originally hypothesized that patellar taping normalized patellar tracking by mechanically shifting the patella.…”

Effect of patellar taping on vasti onset timing, knee kinematics, and kinetics in asymptomatic individuals with a delayed onset of vastus medialis oblique

This randomized within-subject study investigated the effects of patellar tape on the onset of electromyographic (EMG) activity of vastus medialis obliquus (VMO) relative to vastus lateralis (VL), knee kinematics, and kinetics in 12 currently asymptomatic individuals with a VMO timing deficit and a history of patellofemoral pain. Participants were required to complete stair stepping and normal-pace and fast-pace walking tasks under three experimental conditions; no tape, control tape and therapeutic tape. EMG onsets of VMO and VL were measured by surface electrodes, stance phase knee flexion by the PEAK movement analysis system and vertical ground reaction force by a force plate. A two-way repeated measures analysis of variance showed that neither therapeutic tape nor control tape had any effect on the EMG VMO-VL onset timing difference. Therapeutic tape, but not control tape, led to significant increases in stance phase knee flexion. The first peak vertical ground reaction force was lowered by both control and therapeutic tape but only during fast walking. The results suggest that tape induced effects on neuromotor control of the vasti seen in other studies are related to reductions in pain rather than the presence of a baseline timing deficit. However, this cannot explain the improvements in stance phase knee flexion observed with tape. ß
