Abstract

Background: Isokinetic dynamometry offers great clinical and research advantages, in the evaluation and rehabilitation of muscle performance. The aim of this study was to assess the association between hamstring to quadriceps (H:Q) ratio, the quadriceps angle (Q angle) and the effect of anterior knee pain (AKP) on these ratios at different angular velocity.  Methods: 30 adult females; mean age (20±2.6) years with AKP. Biodex isokinetic testing dynamometer was used to measure H:Q ratios at angular velocity of 60°and120°/sec. Q angle was measured by the universal goniometer and pain was measured by visual analogue scale. Results: The results revealed that there is significant positive correlation between Q angles and H:Q ratio at 60°/sec, (P=0.049) (r=0.397 P<0.05). There is a positive correlation between Q angles and H:Q ratios at 120°/sec, but it was not statistically significant (r=0.317, P>0.05). There is positive significant correlation between AKP and H to Q ratio at 60°/s (P=0.049)(r=-0.397 P<0.05) There is positive correlation between AKP and H to Q ratio at (120°/s) but not significant(P=0.597) (r=1.11 P>0.05).Conclusion: A higher Q angle is associated with increased H: Q ratio and decreased power of quadriceps muscle ,at low and intermediate speed torque angles 60°and120°/sec by isokinetic testing. High Q angle-related knee joint disorders and sports injuries can be avoided by quadriceps strength exercises to prevent malalignment of the patella.
