Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Enso is a portable device for the treatment of chronic and acute types of musculoskeletal pain. This study is being designed as a double-blinded, sham-controlled randomized clinical trial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Fifty subjects will be selected based on the inclusion criteria and then randomized to either the intervention group or the sham control group. Each subject will be randomly fitted with an Enso or a sham device and will be instructed to self-administer treatment daily for one hour or more per day for four weeks in both cohorts. Throughout the duration of the study, data will be recorded via a smartphone application regarding treatment usage and intensity, pain levels, the subject's impression of any changes in their functionality, and their opioid and non-opioid medication intake. Medication usage will also be tracked through the use of CURES 2.0 information and pill counts at specified study visits. Additional functional testing will be conducted at each study visit.

At the 4 week visit, the study blind will be broken, and subjects who were randomized to the sham group will be given the opportunity to cross over for an additional week in the study, using the active device.

Participants Caregivers Investigators Outcome Assessors
Devices are assigned per the randomization schedule, with the sham device identical to the active device in every way except that no neuromodulation is delivered. The neuromodulation that the active device delivers can be done in a way that causes no sensation, so subjects are not unmasked.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active or Enso Group

Active Enso device use for one month, at least one hour daily, including coaching via a smartphone app and coaching phone calls regarding device usage.

Group Type ACTIVE_COMPARATOR
