In ARC classification, HAC is defined as which description?

• A. HAC (objective = angle of anomaly)
• B. Unharmonious correspondence
• C. PAC 1
• D. PAC 2

Answer: (A)

ARC classification looks at how sensory findings and motor alignment line up in anomalous correspondence. The description described here for HAC is that the objective measurement of the misalignment exactly equals the angle of anomaly observed. In practical terms, when you quantify the misalignment with objective testing and the resulting angle matches the anomaly angle reported from sensory testing, that pattern fits HAC. This exact match between the objective angle and the angle of anomaly signals this specific type of correspondence. If the two angles don’t match, you’re dealing with unharmonious correspondence, which is different. PAC 1 and PAC 2 describe other distinct patterns of how the angles relate, not simply a direct equality between objective angle and angle of anomaly.
