| dc.title | The effect of patellar taping on medial and lateral quadriceps muscle activities before and after muscle fatigue in subjects with patellofemoral pain syndrome | en_US |
| dcterms.abstract | This study investigated the effects of patellar taping on the electromyographic (EMG) onset of vastus medialis obliquus (VMO) and vastus lateralis (VL), and their respective magnitudes of activities before and after fatigue in subjects with patellofemoral pain syndrome (PFPS). Thirteen subjects (2 males and 11 females) aged between 26 - 45 years diagnosed with PFPS were tested. Their numeric pain rating scale ranged from two to eight out of ten. 85% of subjects had lateral glide, 77% had lateral tilt and 69% had external rotation of the patella. All subjects have not received physiotherapy before. The timing of surface EMG onset and magnitude of contraction in VMO and VL were tested with a postero-anterior perturbation to the knee during single-legged standing. The tests were conducted under three conditions in random orders of real taping, placebo taping and no taping. Afterwards, the subjects performed knee extension exercises until fatigue and the above tests were repeated. There was no significant difference in the EMG onset time and amplitude of VMO and VL contractions among the three conditions (p>0.05) before muscle fatigue. There was also no significant difference in the EMG onset time of VMO and VL among the three testing conditions after muscle fatigue (p>0.05). There was close to significant difference in VMO magnitude after muscle fatigue in the ANOVA model (p=0.092). Further analysis is revealed that VMO was less active in the real taping condition than the placebo and no taping conditions (p=0.041). The present study suggests that patellar taping might not enhance the temporal activation of VMO regardless of muscle fatigue. When the muscle was fatigued, the VMO contraction could be inhibited by patellar taping as compared to placebo or no taping. | en_US |
