The inclusion criteria for FSS include painful restriction of active and passive glenohumeral and/or periscapular motion.

Despite these criteria, diagnosing FSS can be controversial because there is little consensus on the specific shoulder motion restrictions or duration of symptoms needed to qualify a patient as having a frozen shoulder. Although various authors have classified patients with FSS as those with limited abduction from 45-135º, FSS is still primarily a clinical diagnosis based on clinical motion loss and symptoms.
