isometric quadriceps-force measured in an isokinetic dynameter (Biodex III). The patient is sitting in the dynameter-chair with 60° knee-flexion. After a pretest training, instruction and two suboptimal trials, the patient will do 5 maximal isometric knee-extensions.
The highest value measured will be expressed as the quadriceps-force in Nm/Kg bodyweight [1]. The knee circumference will be measured 1 cm proximal to the base of the patella with the patient relaxed in the supine position and the knee extended [13] The Quadriceps circumference will be measured 10 cm proximal to the base of the patella with the patient in supine position and the knee extended.
