Veterans Specific Activity Questionnaire (VSAQ) scores as reported by the first 44 clinic patients. The least intense activity that patients reported made them need to stop is shown in grey bars as VSAQ ‘first/1st’, corresponding to the VSAQ captured in the original protocol.¹² Some patients reported having to stop in two non-consecutive series of activities in terms of exercise intensity—the lowest VSAQ scale value of their second set of activities is denoted as VSAQ ‘second/2nd’ (navy diamond). Where there was no gap, VSAQ ‘second’ is denoted as identical to the VSAQ ‘first’.
