This paper reports a research in which a setup was developed to determine the optimal values of ergonomic positional parameters that would mitigate the development of fatigue while performing massage therapy. This setup was based on virtual instrumentation principles and consisted of a sphygmomanometer bulb, an air sac, a pressure sensor, a data acquisition card and a personal computer installed with the Laboratory Virtual Instrumentation Engineers Workbench software (LABView software). The air sac fitted in this setup is equalised with the muscles and other human body parts which a human therapist is required to press while performing massage therapy. After constructing the air sac fatigue monitoring virtual instrumentation setup, 25 participants who were not actually massage therapists were asked to press the air sac to mimic the behaviour of the massage therapists during the time of their works. After drawing necessary data by performing this activity and by entering the data in Minitab 16 software, regression models to specify optimal values of ergonomic positional parameters were developed. These regression models were practically validated by conducting experiments involving five other participants. The method of utilizing these regression models in determining the optimum values of positional parameters that would mitigate fatigue development while performing massage therapy is illustrated by presenting two cases. While concluding, it is suggested to involve actual massage therapists for testing the performance of the fatigue monitoring virtual instrumentation setup developed during the research reported in this paper.
