Abstract
The Q angle represents an estimate of the resultant force of
the quadriceps on the patella and is a predictor of the lateral movement
of the patella under dynamic conditions. The aim of the present study was
to observe whether Isometric Quadriceps Activation (IQA) can decrease the
Q angle and to identify people at high risk of patellar subluxation. Q angles
were measured in 23 non impaired young women (22.9±2.3 years) in relaxed
standing and during IQA. There was a significant decrease (4.65±2.74°) in
the Q angle values for subjects with IQA as compared to subjects with
measurements in relaxed standing Significance levels were set at P<0.05.
The Q angle decreases with IQA which was highly significant (t=8.01,
P<0.001). The result supports the view that an excessive Q angle may
predispose women to greater lateral displacement of the patella during
vigorous activities and sports in which the quadriceps muscle is stressed.
