Reliability, validity and feasibility of nail ultrasonography in psoriatic arthritis

Among the eight parameters evaluated, power Doppler of the matrix which correlated with local inflammation (DIP joint and bed) and with VAS pain could become an interesting outcome measure, provided that it is also sensitive to change.
