After 6 weeks, the Technohealth Experimental Group as compared to the Control Group reported a significant overall reduction in work-related symptoms [F(8, 19)=3.254, p<.01]. The report of symptoms reduced significantly included muscle strain of the head [ t(23) = 2.24 p < 0.05], neck and shoulder [ t(19) = 2.98, p < .01], wrist and hands [ t(22) = 3.02 p < 0.01], arms [t(22) = 2.16, p < .05], and overall tiredness [t( 24) = .2.35, p < .05]. There were no significant reductions in symptoms reported for the eyes [t(23) = .69, p > .05], back [ t(23) = 1.63, p > .05], and legs [ t(22) = 1.60, p > .05]. See Figure 4.

The Technohealth Experimental Group as compared to the Control Group reported a meaningful overall improvement in work-style changes [F (5, 23)=5.232, p<.001]. Significantly more micro-breaks [ t(25) = 3.74, p < .01], meso-breaks [ t(22) = 5.47, p < .01], and macro-breaks [ t(20) = 4.16, p < .01] were reported. The Experimental Group as compared to the Control Group also practiced more diaphragmatic breathing [ t(22) = 3.36, p < .01] and applied more ergonomic principles at the workstation [ t(21) = 4.56, p < .01]. See Figure 5.
