Data were analyzed by analysis variance to compare the mean scores of groups, and LSD pursuit test was used in case of significant effect of different ipsilateral and contralateral conditions. By analyzing the proposed hypotheses at the P≤ 0.01 demonstrated significant differences among groups in performance.
