outcome measures booked its place as the best tool for this task. Using a responsive
outcome measure will facilitate the detection of moderate treatment effects in both
standard clinical practice and clinical research. Furthermore, the results of a recent
systematic review of surgical and non-surgical CTS treatments highlighted the need
