We have used the usual standardised positioning of the subject and a full description is given by Davis22 and the user's guide of Cybex 6000 (Cybex Division of LUMEX, Ronkonkoma, New York, USA)
The subject was lying down on the Cybex table and was stabilised by a pelvic belt and a torso belt for isokinetic testing of the hip, ankle, and elbow. For the wrist the subject was seated and stabilised on the chair by a pelvic belt and a torso belt. Joints and segments not involved in the measurements were fastened by straps.
The axis of rotation of the dynamometer was placed in front of the joint axis.
An adjustable arm with strapped thigh pad (hip), or hand grips (elbow and wrist), or footstrap (ankle) allowed the tested segment of the left limb to rotate the dynamometer axis.
Full range of motion was tested except for the hip, in which range limitations reduced the motion from -10c extension to +90° flexion to avoid low back pain.
The computer procedure allowed the impact of gravity to be measured and gravity error to be corrected at the same time.
For all these joints the value recorded was the maximum moment or peak torque measured in Newton meters (Nm).
