Percentage of gait cycle time for each phase (Mean and SD). Abbreviations: Pre_DSP, pre-obstacle double support phase; T_SSP, single support phase of trailing limb; Cross_DSP, obstacle-crossing double support phase; L_SSP, single support phase of leading limb; L_Pre_SW, pre-obstacle swing phase of leading limb; L_Post_SW, post-obstacle swing phase of leading limb; T_Pre_SW, pre-obstacle swing phase of trailing limb; T_Post_SW, post-obstacle swing phase of trailing limb. Asterisks indicate differences between groups *P < 0.05
