Efficacy rate (or success rate) in each technique can be expressed as the ratio of the magnitude of the gain obtained T₀–T_{1 (}difference between T₀ at pre-session and T₁ at post-session state sumscore) to the maximum potential gain. It shows the percentage of the maximum expected improvement reached. T₀ state being adjusted with the ANCOVA to 41.73, the maximum potential gain in each technique is 41.73-20 = 21.73. Thus, efficacy rate of each technique is: Fs 13.92/21.73, Rf 15.92/21.73, Hp 15.88/21.73, Mt 10.10/21.73, Rt 6.38/21.73.
