title: Quadriceps strength deficit associated with rectus fernoris rupture: a case report.
abstract: We report a case of rectus femoris rupture of the quadriceps muscles. Isokinetic muscle testing was undertaken at joint angular velocities of 60, 120, 180, 240, and 300 deg s(-1) to establish the knee extensor muscle strength deficits associated with this condition. The mean strength deficit over these joint angular velocities was 16.6%.
