Is this trial a fit for you?

Likely a good fit

Adults 18 or older with a primary lower back pain complaint who can lie prone, are not pregnant or breastfeeding, can provide informed consent, and meet the other listed safety criteria are ideal candidates.

Probably not a fit

People who are pregnant or breastfeeding, cannot remain prone, have bleeding disorders, local skin allergies/affectations, implanted devices in the massage area, or who used pain treatments or investigational drugs within the exclusion windows may not benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Outpatient adults with a primary complaint of lower back pain are enrolled and randomized to receive either hands-on massage from a certified massage therapist or an EMMA (Expert Manipulative Massage Automation) massage operated by a certified therapist. Baseline pain intensity is recorded and participants must meet standard safety and positioning criteria. The study collects patient-reported experience and tolerability data after the assigned massage session. All procedures are performed at a single Mayo Clinic location in Rochester, Minnesota.

Why it matters

Potential benefit: If successful, this approach could expand access to standardized massage care and offer a consistent, technology-assisted option for people with lower back pain.

How similar studies have gone: Automated massage devices have been tested in small studies with mixed results, and direct randomized comparisons to therapist-delivered massage remain limited.
