Study summary

The investigators are looking to see if using a mirror during knee exercises after a knee replacement helps participants with less pain and/or better knee range of motion.

Read the detailed description

Purpose: To examine the effectiveness of mirror therapy combined with standard care physical therapy on knee range of motion (ROM), pain levels, and physical function in individuals following a total knee arthroplasty (TKA).

Background: Following a TKA, patients often present with numerous impairments including joint stiffness, pain, decreased strength, and impaired mobility. These limitations can inhibit functional progress during rehabilitation and recovery. Mirror therapy is a potential treatment option that may assist in reducing these impairments and improving recovery following TKA.

Study Activities: Active and sham group activities will add-on to the physical therapy session and are considered part of standard care, with no change to the current billing process. Both groups will participate in ROM activities, consistent with standard PT care, as part of a billable treatment. The active group with do standard practice ROM activities while looking at a mirror and the sham group will perform ROM activities without a mirror.

Interventions:

  • Treatment will start within 2 weeks (14 days) of the total knee replacement.
  • There will be 8 sessions within a 4-week time frame.

Data Analysis: Demographic information will be reported using descriptive statistics. Analyses will use linear mixed-effects models with fixed effects for Group, Time, and the Group × Time interaction, and with subject-level random effects to account for repeated measures. The primary inference will be the Group × Time interaction.

What researchers measure

Primary outcomes

  1. Pain NRS (Pain Numerical Rating Scale)

    Subject rates pain from 0-10 with 0 being no pain and 10 being the worst pain

    Time frame: Every visit, visits 1, 2, 3, 4, 5, 6, 7 & 8. Visits start within 14 days of the TKA and occur a total of 8 times within a 4 weeks time frame.

  2. Knee Flexion and Extension Goniometry

    A measurement of knee flexion and knee extension, using a goniometer, will be completed.

    Time frame: Every visit, visits 1, 2, 3, 4, 5, 6, 7 & 8. Visits start within 14 days of the TKA and occur a total of 8 times within a 4 weeks time frame.

Secondary outcomes

  1. Gait Speed

    Subject's gait speed will be measured in meters/second.

    Time frame: Visit 1 and visit 8. Visits start within 14 days of the TKA and occur a total of 8 times within a 4 weeks time frame.

  2. Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS Jr)

    Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS Jr) is a short, 7-question survey used by doctors to quickly assess a patient's knee pain, stiffness, and daily function. The raw score is converted to a 0-100 scale with a score of 0 = total disability and 100 = full function without pain.

    Time frame: Visit 1 and visit 8. Visits start within 14 days of the TKA and occur a total of 8 times within a 4 weeks time frame.

Start is estimated for Feb 2026; primary completion for Aug 2026, 6 months later.

Of 3,731 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 6 months is below that.

Counting every sponsor, half of 3,830 studies reached it within 10 months; a quarter within 4 and three quarters within 23.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 2, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
