“…This robot also increased perceived comfort of users, muscle pain management, increased perceived heat, and promoted functional motor recovery (e.g., mouth opening, blood circulation, saliva production, muscle thickness (Koga et al, 2008;Ariji et al, 2009aAriji et al, ,b, 2010Ariji et al, , 2015Ariji et al, , 2016Ishii et al, 2009;Obokawa et al, 2009;Solis et al, 2009;Hiraiwa et al, 2013;Table 8). Other similar robotics projects provided promising results with a drop in lumbar strain, heart rate and muscle activity (Peng et al, 2010;Luo and Chang, 2011;Hu et al, 2013;Table 8). Finally, a robotic massage system achieved attractive performance on relaxation by a respective decrease and increase of beta and alpha powers (Luo et al, 2016;Table 8).…”
