Dear collegue.
The results of Gilleard et al, (1999)is only one study most likely the results of a type I error. The evidence of VMO and VL being two different muscles come from the study of Perry and Lieb (1968) Journal of Bone and Joint Surgery. Only six cadavers were study. He concluded that VMO is a different muscle to the VL due to its fuction; when a pulley was applied to the muscle the only movement obtained was medial displacement of the patella. Also, only one cadaver demostrated a fascia separating the VMO from the VL and only this cadaver demonstrated a branch of the femoral nerve dividing into two one for VMO and VML. Since, this study, all the studies with samples larger than 100 do not report the VMO as a separate muscle to the quadriceps group.

Dear nicaragua,
Despite answering your own query, it may help to read a previous post "VMO selective strengthening" as similar issues have been raised.
In particular, Gilleard et al (1998) certainly do provide evidence that patellar taping does something. VMO onset times were changed in both symptomatic and non-symptomatic subjects while attempting stair ascent & descent, with the authors hypothesising that a minor change in joint congruence may have occurred.
While certainly not the end to this issue - a large body of evidence refutes any suggestion that alteration of PFJ congruence exists in symptomatic subjects measured by X-ray, CT or MRI (refs not immediately at hand) - it does add to the idea that tape does more than reduce pain.
Skin irritation tends to occur with repeated removal of the the tape and rigid tape directly on the skin. Fixomul or Hypafix porous and breathable adhesive tapes might help if this is the case.
