The patients with patellofemoral joint pain when moving from
a bilateral to a unilateral stance, did not show this typical predictable
response on their symptomatic leg, with the Q angle found
being significantly greater than the value predicted using the
predictive linear regression equations reported in this study. This
pattern did not occur in their asymptomatic leg of the patellofemoral
pain patients, were the Q angle followed the predicable
decrease expected.
