Fig. 2. VAMS and EMG data for the biceps brachii muscle. (A) VAMS scores changed significantly after watching both the happy and sad videos, but VAMS score changed more after watching sad video than after watching happy video. (B) EMG values were presented by %MVIC and they were not different before and after watching happy or sad videos. However, the initial EMG values were lower when the subjects watched happy videos. The mean and standard error were shown. The significance level was represented by *p < 0.05. VAMS, visual analog mood scale; %MVIC, % maximum voluntary isometric contraction; NS, no significant effect between before and after watching the video; EMG, electromyography.
