During the Scratch Collapse Test (SCT), the patient stands facing the examiner with elbows flexed at 90 degrees. The examiner applies a scratch or swipe over the skin covering the nerve suspected of compression while the patient maintains resistance. A positive test occurs if the patient involuntarily loses resistance, indicating nerve dysfunction.
