  1. ES = effect size (mean of change÷ standard deviation of baseline), SRM = standardised response mean (mean of change ÷ SD of change)
  2. A negative ES or SRM denotes a decrease in score from baseline. In 2PD (mm distance) and the BCTQ subscales (scored 1 to 5) a decrease or negative value indicates an improvement, whereas for all four motor tests a negative value indicates a decline in strength (Newtons).
