Passive Range of Motion (PROM) of the Shoulder

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
Spasticity
Hard capsular
Soft capsular
Bone to bone
Empty (due to pain)
Springy block

Protective spasm following injury

Spasm resulting from instability or pain

Tight muscle
Upper motor neuron lesion
Frozen shoulder
Synovitis, soft tissue edema
Ostephyte formation
Acute subacromial bursitis
Meniscus tear

 

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.
