Planes of motion: S - Sagittal plane; F - Frontal plane; T - Transverse plane
R - rotational motions
332
Briefly describe the SFTR method of recording joint ROM
The letter representing the plane of motion being assessed is written followed by three numbers, the starting position is recorded as the middle number, and the ROM present on either side of the starting position is recorded before and after the start position (i.e. motion occurring in the sagittal plane is extension / flexion, the number to the left of starting position is extension and the number to the right is flexion - shoulder left S: 60-0-180 degrees; right S:60-0-80 degrees)
Motion in the Frontal (F) Plane is abduction (number to the left of start postion)/ adduction (number to right)
Motion in the Tranverse (T) plane is horizontal abduction & horizontal adduction and retraction / protraction. The number on the left indicates H. abduction / retraction and the number on the right indicates H adduction / protraction
R represents rotational motion. The number on the left represents ext. rotation, forearm supination, or spinal rotation to the left, and the number on the right represents int. rotation, forearm pronation, and spinal rotation to the right.
333
When assessing & measuring joint ROM with two- or multi-joint muscle in the same region, the PT should do what?
Move the nontest joint crossed by the muscle into position so that the two-joint or multi-joint muscle is placed on slack (i.e. when the hip is flexed to asses hip flexion, the knee is also placed in knee flexion to relax the hamstring muscles in order to prevent restriction of the hip flexion ROM due to passive insufficiency of the hamstrings)
