PROM is usually done when you can observe limited ROM during AROM. The goal of PROM is to obtain the end-feel of the joint to determine what is limiting full range of motion. The following table shows an overview of „normal“ and „abnormal“ kinds of end-feels:
End Feel | Example |
NORMAL | |
Hard (Ligamentous) Soft tissue approximation Tissue stretch |
Elbow extension Knee flexion Ankle dorsiflexion, shoulder lateral rotation, finger extension |
ABNORMAL | |
Early muscle spasm
Late muscle spasm ‘Mushy’ tissue stretch |
Protective spasm following injury
Spasm resulting from instability or pain Tight muscle |
The normal end-feel for different movements is as follows:
Abduction: Bone to bone or tissue stretch
Horizontal adduction: Tissue stretch
Flexion: Tissue stretch
Extension: Tissue stretch
Lateral/External Rotation in 90° of abduction: Tissue stretch
Medial/Internal Rotation in 90°: Tissue stretch
Note: As the shoulder is a complex structure consisting of four different joints, it is necessary to fixate properly if your goal is to look for limitations in one particular joint.
