Background and Motivation• More than 400,000 TKAs are performed per
year. More are expected with aging baby boomers reaching 65 yr of age.
• The operation typically involves substantial postoperative pain, and includes vigorous physical rehabilitation.
• Healthcare dollars allotted to rehabilitation declining.

Need to develop remote monitoring of rehabilitation after TKA
• To enable better adherence with exercise protocols
• Optimize self-management of recovery• Variation in patient’s independent exercise
and activity after TKA surgery may contribute to variable functional gains (Franklin et al., 2006)

StepRite System• Developed by MedHab (http://www.medhab.com/)
• Allows the physical therapist to monitor physical
activity and exercise remotely
• StepRite provides a pressure sensing dashboard for
the physical therapist and physician.
• It provides 3D tracking, pressure sensing, real-time
wireless communication and a HIPAA secured user
interface website.

StepRite System
• Provides quantitative feedback about
exercise compliance comparing the surgical
side with the non-surgical side
• Real time feedback during exercise and
weight-bearing activities
• It is a developing remote, interactive
monitoring system

Algorithm Development• Custom algorithms needed
– Translate raw sensor data into various information• Gait Analysis• Range-of-Motion analysis• Power Meter

Stage of Research• Intervention development• Intervention efficacy
![Page 26: Remote Monitoring of Rehabilitation after Total Knee Replacement: The StepRite System Carolee Winstein, Christopher Powers, Helen Bacon Industry Sponsor:](https://reader035.fdocuments.in/reader035/viewer/2022070323/56649d6f5503460f94a509d0/html5/thumbnails/26.jpg)

Project Objective:• We will test the hypothesis that patients who use
the device post-surgery will demonstrate
superior short-term improvements (i.e., 6 months
post TKA)—two outcome measures:– Self-reported functional outcomes (WOMAC)
– Gait parameters (GaitRite system)
• Compared to a control group who does not use the
device (standard care with log book).

Specific Aims:• To compare the short-term changes in gait
parameters after TKA between those who use the StepRite device and those who follow a standard therapy program with out the device.
• To compare the short-term self-reported functional outcomes after TKA between those who use the StepRite device and those who follow a standard therapy program without the device.

Work in progress
• Exercise protocol will be programmed into the device.
• IRB and development of industry partner contract.
• Development of protocol including the number of HH
(home health) and OP (out-patient) visits (in-person
and remote) for each group.
• N= 25/group for the efficacy study
• Proposed time line (~1-1.5 yr project)
