3. Fig 2
Mean time in different phases of gait cycle. The means and standard deviations (SDs) of the duration in double-stance phase I, single stance, double-stance phase II, and swing phase of Tai Chi gait (TCG) in both young and elders and of normative gait (NG) in elders. *Significant difference between young and old in Tai Chi gait; †significant difference between Tai Chi gait and normative gait in elders.

4. Fig 3
The means and SDs of (A) maximum joint motion during single-stance phase and (B) joint ROM during swing phase, of Tai Chi gait and normative gait, in the young and old groups. Abbreviations: Ab/Ad, abduction and adduction; D/P, dorsiflexion and plantarflexion; F/E, flexion and extension. *Significant difference between young and old in Tai Chi gait; †significant difference between Tai Chi gait and normative gait in elders.

5. Fig 4
The means and SDs of (A) activation time of 6 muscles, (B) RMS values of 6 muscles, and (C) coactivation time of 5 muscle pairs, during single-stance phase of Tai Chi gait and normative gait, in the young and old groups. The activation time and coactivation time are normalized by the single-stance time, and the RMS value of each muscle electromyographic activity is normalized by the corresponding RMS value during quiet stance. Abbreviations: PL, peroneus longus; RF, rectus femoris; SOL, soleus; ST, semitendinosus; femoris TA, tibialis anterior. *Significant difference between young and old in Tai Chi gait; †significant difference between Tai Chi gait and normative gait in elders.
