Methods for taking subtalar joint measurements. A clinical report.

Physical therapists frequently evaluate the lower extremity, and this evaluation often includes measuring the subtalar joint neutral (STJN) position and subtalar joint (STJ) passive range of motion (PROM). This report critically reviews methods used to measure STJN position and STJ PROM. Standardized methods for taking these measurements, which have been clinically tested and appear to be theoretically sound, are presented. Although these methods are based on anatomical considerations, their reliability is less than optimal. However, these are the only methods of measuring STJN position and STJ PROM that have been tested adequately for reliability.
