And resources to maximize their impact!
Whether you have knee pain that comes and goes or severe arthritis that is worsening with time, therapy exercises offer a proven way to improve your symptoms.
The combination of our experience treating people with symptomatic knees and medical studies about knee pain informed the creation of our online therapy program and products. Below are the studies we reviewed and conducted and additional resources.
Long Distance Running and Knee Osteoarthritis A Prospective Study
This 2018 article, originally published by the National Library of Medicine (NLM), describes how it does not matter if you run long distances or not. Long-distance running does not increase your chance of developing osteoarthritis. Abstract Background Prior studies of...
Hip muscle strength and protection against structural worsening and poor function and disability outcomes in knee osteoarthritis
Originally published by the National Library of Medicine (NLM) in 2019, this study demonstrates that having and maintaining hip abduction strength helps maintain function and decrease symptoms. Abstract Objective Examine associations of hip abductor strength...
Deconditioned Knee: The Effectiveness of a Rehabilitation Program that Restores Normal Knee Motion to Improve Symptoms and Function
This article, Originally Published by the National Library of Medicine in 2007, states that re-establishing range of motion helps with knee pain. Abstract Background Knee pain can cause a deconditioned knee. Deconditioned is defined as causing one to lose physical...
Instructions For Proper Use of the LRU Pillow
The sooner the patient’s leg is placed in the LRU Pillow,the better. Placement in the recovery room would be ideal. The heel should not hang over the distal end of the pillow any further than 1 inch over the edge of the pillow. This defeats the purpose of keeping the...
Why is early post-operative knee flexion and extension range of motion important with total knee arthroplasties?
Download PDF Version Studies have shown that the current measures of success following a total knee replacement (pain and ROM) may not be enough to ensure a positive experience and a return to safe functional levels (ref.3). 24% fall within the first year ( 4). Total...
The Effects of the LRU Pillow versus the CPM Machine on Active Assistive Knee Range of Motion at Hospital Discharge. A Retrospective Summary
Investigators: Scott Johnson, PT , Jennifer Delcamp, MD, and Matthew Lawless, MD Background: Pain relief and return of function are the main goals following total knee arthroplasty. One measure of return of function in the acute phase has been range of motion. A...
Cochrane Review Summary For Use of CPM machine with TKA
Download PDF Version Twenty randomised controlled trials of 1335 participants met the inclusion criteria. There is high-quality evidence that continuous passive motion increases passive knee flexion range of motion (mean difference 2 degrees, 95% CI 0 to 5) and active...
Effects of the LRU pillow on active assistive knee range of motion and pain scores following Total Knee Replacement Surgery
Download PDF Version A main goal following Total Knee Arthroplasty (TKA) is, in addition to pain relief, restoration of function. A continuous passive motion (CPM) machine is frequently used to help achieve this goal. However the efficacy of the CPM machine has not...
