CONCLUSION AND DISCUSSION: The results suggest that neither exercises purported to selectively activate VMO activity nor patellar taping improve the VMO/VL ratio over similar exercises.


Neg (nor) Positive_regulation (activate) of VMO in VMO
1) Confidence 0.67 Published 1995 Journal Phys Ther Section Body Doc Link 7644571 Disease Relevance 0 Pain Relevance 0
RESULTS: When participants ascended the steps with pain, the onset of VMO EMG was delayed relative to that of VL, in contrast to simultaneous or earlier activation of VMO EMG in the pre- and postpain trials.
Positive_regulation (activation) of VMO EMG
2) Confidence 0.43 Published 2009 Journal Arthritis Rheum. Section Body Doc Link 19116977 Disease Relevance 0.14 Pain Relevance 0
BACKGROUND AND PURPOSE: The purpose of this study was to determine which of selected exercises with and without the feet free to move would enhance vastus medialis oblique muscle (VMO) activity over that of the vastus lateralis muscle (VL) and whether the use of taping would increase VMO activity.
Spec (whether) Positive_regulation (increase) of VMO in vastus medialis
3) Confidence 0.39 Published 1995 Journal Phys Ther Section Abstract Doc Link 7644571 Disease Relevance 0.07 Pain Relevance 0.07
BACKGROUND AND PURPOSE: The purpose of this study was to determine which of selected exercises with and without the feet free to move would enhance vastus medialis oblique muscle (VMO) activity over that of the vastus lateralis muscle (VL) and whether the use of taping would increase VMO activity.
Spec (whether) Positive_regulation (enhance) of VMO in vastus medialis
4) Confidence 0.39 Published 1995 Journal Phys Ther Section Abstract Doc Link 7644571 Disease Relevance 0.07 Pain Relevance 0.07
RESULTS: One exercise demonstrated greater activation of the VMO over the VL when compared with similar exercises in subjects without PFP syndrome.
Positive_regulation (activation) of VMO in VMO
5) Confidence 0.39 Published 1995 Journal Phys Ther Section Body Doc Link 7644571 Disease Relevance 0 Pain Relevance 0
OBJECTIVES: To compare the onset timing and activation of the vastus medialis oblique (VMO) and vastus lateralis (VL) between subjects with and without patellofemoral pain syndrome (PFPS) at various step heights.
Positive_regulation (activation) of VMO in vastus lateralis
6) Confidence 0.38 Published 2007 Journal J Orthop Sports Phys Ther Section Body Doc Link 17549952 Disease Relevance 0 Pain Relevance 0
A common rehabilitation strategy for patellofemoral pain syndrome (PFPS), which lacks scientific evidence, includes pulling the patella medially with tape to reduce pain and increase the vastus medialis oblique (VMO) muscle activity.
Positive_regulation (increase) of VMO in patella associated with pain and patellofemoral syndrome
7) Confidence 0.38 Published 2004 Journal J Electromyogr Kinesiol Section Abstract Doc Link 15165599 Disease Relevance 0.61 Pain Relevance 0.61
Although patellar taping did not influence leg press force (P > 0.05), it increased the VMO activity and decreased the VL activity in PFPS subjects but had the opposite effect in healthy subjects.
Positive_regulation (increased) of VMO in leg associated with patellofemoral syndrome
8) Confidence 0.38 Published 2004 Journal J Electromyogr Kinesiol Section Abstract Doc Link 15165599 Disease Relevance 0.89 Pain Relevance 0.96
When the patellofemoral joint was taped, the VMO was activated earlier than the VL during the step-up and step-down tasks.
Positive_regulation (activated) of VMO in VMO
9) Confidence 0.38 Published 1998 Journal Phys Ther Section Body Doc Link 9442193 Disease Relevance 0 Pain Relevance 0
The earlier activation of the VMO may alter the movement of the patella, and further research is needed to determine whether this occurs and whether it is beneficial.


Positive_regulation (activation) of VMO in VMO
10) Confidence 0.38 Published 1998 Journal Phys Ther Section Body Doc Link 9442193 Disease Relevance 0 Pain Relevance 0
This often is achieved by taping the patella, which not only decreases the pain but also promotes an earlier activation of the VMO and increases quadriceps torque.
Positive_regulation (activation) of VMO in quadriceps associated with pain
11) Confidence 0.38 Published 2002 Journal Clin Sports Med Section Abstract Doc Link 12365233 Disease Relevance 0.19 Pain Relevance 0.19
Stretch applied to the skin over the patella increased VMO surface EMG and was greatest with lateral stretch.
Positive_regulation (increased) of VMO in patella
12) Confidence 0.10 Published 2005 Journal J. Orthop. Res. Section Abstract Doc Link 15734248 Disease Relevance 0.36 Pain Relevance 0.36
Application of stretch to the skin over VMO via the tape can increase VMO activity, suggesting that cutaneous stimulation may be one mechanism by which patella taping produces a clinical effect.
Positive_regulation (increase) of VMO in patella
13) Confidence 0.10 Published 2005 Journal J. Orthop. Res. Section Abstract Doc Link 15734248 Disease Relevance 0.31 Pain Relevance 0.31
