Figure 2

The condition of intervention (black dot: tactile-off, white dot: tactile-on). Five interventions (a–e) were applied for 20 min (stim on/stim off: 1 s/5 s).

(a) Simple intervention

(b) Lateral complex intervention

(c) Rubbing intervention

(d) Vertical complex intervention

(e) Random complex intervention
