About

This is a trial comparing self-directed rehabilitation using the Zimmer Biomet mymobility digital platform versus standard office-based physical therapy after reverse shoulder replacement. The investigators hypothesize that there will be no difference in the postoperative outcomes between the mymobility cohort and the standard office-based physical therapy cohort.

Full description

This is a prospective, multicenter, randomized controlled trial comparing a self-directed rehabilitation protocol using the Zimmer Biomet mymobility digital platform versus standard office based physical therapy protocol after reverse total shoulder arthroplasty.

Subjects will be randomly assigned to the Treatment Cohort (mymobility Physical Therapy) or the Control Cohort (Standard Office-based Physical Therapy). Randomization will occur following completion of a signed consent form. Each Participating Site will receive sealed, numbered randomization envelopes from the Lead Site.

The treatment cohort is mymobility PT. If the subject is randomized to this cohort, the Participating Site will assist the subject to download the mymobility mobile application (app) during the preoperative visit. The app has a video of each of the exercises to be completed per phase of the rehabilitation protocol beginning on postop day one.

The control cohort is Standard office PT. Home exercises begin on postoperative day one with office visits beginning after the 2 week postoperative visit.

Subject data will be collected through the 6-month postoperative visit.

100 participants in 2 patient groups

mymobility Physical Therapy

Experimental group

Description:

The mymobility Physical Therapy cohort will complete an identical protocol to the Standard Office-based Physical Therapy cohort with one exception: the mymobility cohort's therapy for the entire duration of the protocol is administered at home through the mymobility application. This cohort initiates use of the mymobilty application one postoperative day 1. Exercises and restrictions are described in-depth in the Study Protocol document.

Treatment:

Other: mymobility Physical Therapy

Standard Office-based Physical Therapy

Active Comparator group

Description:

The Standard Office-based Physical Therapy cohort completes an identical protocol to the mymobility Physical Therapy cohort with one exception: rather than through use of the mymobility application, the Standard Office-based Physical Therapy cohort's protocol is administered through the traditional means of an exercise handout for postoperative day 1 through 2 weeks followed by formal office-based physical therapy for the duration of the protocol. Exercises and restrictions are described in-depth in the Study Protocol document.
