Physical Therapy Program and Treatment Expectations in Knee Osteoarthritis
24. mai 2026 oppdatert av: Levent Karataş, Gazi University
Evaluating The Predictive Effect of Treatment Expectations on Response to A Physical Therapy Program in Patients With Knee Osteoarthritis
To our knowledge, no studies have been conducted in the literature investigating the relationship between the success of physical therapy programs applied in knee osteoarthritis and patients' pre-treatment expectations.
The rationale for this study is to demonstrate the possible relationship between treatment expectations and the benefits seen from conventional physical therapy programs in patients with knee osteoarthritis, and to provide clinicians with a different perspective in knee osteoarthritis treatment planning.

Detaljert beskrivelse
Osteoarthritis, also called degenerative joint disease, primarily occurs in old age, but can also develop after trauma or secondarily to diseases such as rheumatoid arthritis and hemochromatosis.
Osteoarthritis is the most common joint disease worldwide.
The pathophysiology of osteoarthritis is responsible for the failed repair of joint damage caused by stress initiated by any joint or periarticular tissue abnormality.
The most common symptom of osteoarthritis is pain.
Factors associated with an increased risk of knee osteoarthritis include advanced age, family history, overweight or obesity, a history of knee trauma, occupational factors, and varus or valgus alignment.
Long-term complications of osteoarthritis include decreased physical activity, loss of fitness, sleep disturbances, fatigue, and depression.
With the increasing aging population, degenerative joint problems have become a concern for a large part of society.
Exercise is a key component in the treatment of this chronic disease, which restricts functionality and reduces quality of life.
A systematic review of 54 randomized controlled trials involving a total of 5362 participants showed that different types of exercise improved pain, functionality, and quality of life in knee osteoarthritis.
Studies have shown that treatment outcomes are not always similar in patients undergoing similar treatment programs, and that patients' expectations from treatment can also influence results.
A systematic literature review on improvement expectations revealed that in 15 out of 16 studies, positive patient expectations were associated with better health outcomes.
A recent study in the field of physical therapy also showed that in the treatment of chronic low back pain, high patient expectations were associated with the success of the treatment.
Therefore, we planned this study to answer the questions of whether treatment expectations have a predictive effect on the benefits seen from an exercise program in patients with knee osteoarthritis, and whether it is necessary to evaluate the level of expectations when creating a treatment program for patients with knee osteoarthritis.

The Western Ontario and McMaster Universities Arthritis Index (WOMAC) score
Tidsramme: From enrollment day to the end of the rehabilitation program at 4 weeks
|
WOMAC score evaluation following the last treatment session.
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a widely used, validated questionnaire designed to assess pain, stiffness, and physical function in patients with knee and hip osteoarthritis.
It consists of 24 items divided into three subscales: pain (5 items), stiffness (2 items), and physical function (17 items).
Patients rate their symptoms on a Likert scale, with higher scores indicating worse pain, stiffness, or functional limitations.
The WOMAC is commonly used in clinical research to evaluate the efficacy of various treatments for osteoarthritis.

Tidsramme |

|
Smertenivå; VAS-poengsum
Tidsramme: Fra innmeldingsdag til avslutning av rehabiliteringsprogrammet ved 4 uker
|
Visual Analog Scale (VAS) er et verktøy som brukes til å måle en pasients smertenivå.
Den består av en rett linje med endepunkter som definerer ekstreme grenser som "ingen smerte" og "verst tenkelig smerte."
Pasienten markerer på linjen det punktet de føler representerer deres oppfatning av deres nåværende tilstand.
Denne metoden er enkel, pålitelig og mye brukt i både kliniske og forskningsmiljøer for å kvantifisere smerteintensiteten.

Timed Up and Go Test (TUG)
Tidsramme: From enrollment day to the end of the rehabilitation program at 4 weeks
|
A rapid, standardized clinical tool used to measure a person's functional mobility, dynamic balance, and fall risk.
It measures the time it takes for a person to get up from a chair, walk 3 meters (10 feet), turn around, walk back, and sit down again.

From enrollment day to the end of the rehabilitation program at 4 weeks
|
|
Stair Climbing Test (SCT)
Tidsramme: From enrollment day to the end of the rehabilitation program at 4 weeks
|
The stair climbing test assesses lower body strength, functional capacity, and cardiopulmonary fitness by measuring how quickly you can safely climb and descend a flight of stairs.
Versions are available with 3 to 12 steps; this study will use the 12-step version.
