Satisfaction and Feasibility Evaluation of an Electronic Massager-Expert Manipulative Massage Automation (EMMA): A Pilot Study.

Background: Electronic massagers have gained popularity for their non-invasive and cost-effective approach to healthcare. However, existing electronic massagers require manual manipulation, leading to inconsistency.

Objective: To investigate the feasibility and acceptability of the Electronic Massager-Expert Manipulative Massage Automation (EMMA) among the American population.

Methods: A single-arm pilot study was conducted at Mayo Clinic Rochester campus. Participants received massage therapy with the EMMA treatment model and completed a demographics and Satisfaction Survey Questionnaire. Data were collected using REDCap, and statistical analysis was performed.

Results: Twenty healthy volunteers (13 women, 7 men; median age, 47 years) participated and completed the intervention within 2 weeks. No adverse events were reported. Overall, the acceptability and satisfaction of massage utilizing EMMA were high, with all participants finding the study worthwhile, willing to participate again, and willing to recommend the study to others. Regarding the overall experience, 65.0% reported a better-than-expected experience. Responses to open-ended post-treatment questions showed that most participants enjoyed the warmth (35%), pressure (25%), and relaxation (20%) provided by EMMA, with the majority suggesting no changes or improvements were needed. However, some participants expressed a desire for an expanded massage area (20%).

Conclusions: This study suggests that the EMMA massager has high acceptability and satisfaction among healthy volunteers, thus demonstrating its feasibility. However, further research is needed to optimize EMMA and assess its clinical effectiveness.
