Rehabilitation Exercise Using Digital Healthcare System in Patients With Total Knee Arthroplasty

January 4, 2022 updated by: Jae-Young Lim, Seoul National University Bundang Hospital

New Model of Short-term Rehabilitation Exercise Training Using Digital Healthcare System in Patients With Total Knee Arthroplasty; Randomized Controlled Study

The study aims to examine the effect of short-term rehabilitation exercise support using digital healthcare system (Uincare homeplus) in the patients with total knee arthroplasty. The study is a two-arm prospective randomized controlled study comparing the effect of rehabilitation exercise digital healthcare system at home with conventional brochure-based home exercise. Gait speed (4-meter), Pain (using Numerical rating scale), knee joint range of motion (ROM), lower extremities motor power (using Manual muscle test), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Berg Balance Scale (BBS) and quality of life using EQ-5D-5L will be evaluation on enrollment, 3-weeks, 6-weeks, 12-weeks and 24-weeks after enrollment.

Detailed Description

Total knee arthroplasty is treatment of choice for knee degenerative arthritis patients who are unresponsive to non-operative management including medications and physical therapies. Total knee arthroplasty is an effective treatment enhancing the joint range of motion as well as reducing pain and correcting deformities which leads to better patient function with better quality of life. Current method of post-operative rehabilitation is home-based self rehabilitation using brochure, combined with one or two times of education at the hospital before discharge. Patients often find difficulty in doing rehabilitation by themselves at home without supervision which resulted in decreased compliance.

With development of technologies using multi-motion sensor and AR(augmented-reality) system, the investigators have developed a digital healthcare system(Uincare Homeplus) which can supplement patients' rehabilitation at home by giving them proper instructions as well as feedback. In this prospective randomized controlled study, the investigators aim to compare the efficacy of the newly-developed digital healthcare system with conventional rehabilitation program.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Conventional Rehabilitation
Other: Conventional Rehabilitation
Home-based self-rehabilitation using brochure for 12 weeks post surgery.
EXPERIMENTAL: Digital Healthcare System Rehabilitation
Device: Rehabilitation using Digital Healthcare System (Uincare Homeplus)

Uincare Homeplus is a device using infrared, kinect camera and motion capture technology to track 3D motion of the patients' posture and joint articulations. It also has embedded exercise training software dedicated to total knee arthroplasty post-op rehabilitation at home.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes from Baseline Gait Speed
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Gait Speed is measured by the time required to walk 4-meters in plain indoor. Shorter time required to complete 4-meter walk means better gait function.
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Numerical Rating Scale (NRS) on the affected knee
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Evaluation of pain of the affected shoulder using numerical rating scale (0-10, with score 0 indicating no pain). the higher score means worse pain.
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Range of Motion (ROM) on the affected knee
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Evaluation of change of ROM in the affected knee from baseline to 24 weeks
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Manual Muscle Test (MMT) on the affected lower extremities
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Evaluation of change of MMT in the affected lower extremities from baseline to 24 weeks. affected lower extremities MMT scales from 0-25, higher score meaning better outcome.
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) on the affected knee
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
The WOMAC is a self-administered questionnaire used in the evaluation of knee osteoarthritis. It is consisted with 24 items divided into 3 subscales; Pain, Stiffness and Physical function. WOMAC score ranges from 0-96 with higher score meaning worse pain, stiffness and function.
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Berg Balance Scale (BBS)
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
BBS is a 14-item objective measure that assess static balance and fall risk in adults. BBS score ranges from 0-56, with higher score meaning better balance.
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Quality of Life using EQ-5D-5L
Time Frame: Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
Evaluation of quality of life using EQ-5D-5L. This scale is numbered from -0.066 to 0.904. Lower value means worse quality of life
Enrollment, 3-weeks, 6-weeks, 12-weeks, 24-weeks
