Fig. 1 — Illustration of the ratio of integrated electromyography and maximum electromyography (EMG) values of each Tai Chi movement to walking values of each muscle. BKTS: Brush Knee & Twist Step, EMG: electromyography, iEMG: integrated EMG, LFS: Lateral Forward Step, RM: Repulse Monkey, TC: Tai Chi, WHIC: Wave-hand in Cloud. The left bottom chart of medial gastrocnemius doesn’t include the EMG data values from two static Tai Chi movements because the EMG signal were missing due to problems with the EMG sensors’ batteries. ∗ p ≤ 0.001, vs. walking; ˆ p ≤ 0.05, vs. walking.
