About this study

In this project, investigators aim to investigate the effects of action observation therapy on pain, fear of movement, functional level and brain hemodynamics in patients with knee osteoarthritis. The study is unique in that this method, which has already been used for post-surgical or motor healing, aims at long-term administration for the first time with chronic pain and objective visualization of the results. This study will create a new perspective to understand the physiology of pain, which has attracted much interest in the literature in recent years, and will shed light on the studies that can be done in this regard. Participants' joint range of motion in the initial assessments will be measured by electro-goniometer, muscle strength assessment by JTech hand dynamometer at appropriate evaluation positions. In assessing pain, pain levels at rest and during activity will be questioned using Visual Analog Scale. Fear of movement of individuals will be assessed via Tampa Kinesiophobia Scale and functional levels will be assessed via Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Timed Up and Go Test. Functional near infrared spectroscopy (fNIRS) will be used for evaluation of brain hemodynamics. The first group, will receive exercises with action observation therapy; and the second group will receive only exercises. The exercise programme will be administered under physiotherapist supervision for three days a week for six weeks. The evaluations will be repeated at the beginning of the study and at the end of the sixth week. Data obtained from the study will be analyzed using appropriate statistical methods.

Read the detailed description

Osteoarthritis is a degenerative joint disease associated with pain and disability that occurs in 25% of the population over 18 years of age Worldwide. It is expected that osteoarthritis will be the fourth most common cause of disability in the World by 2020. Osteoarthritic joint has pathological changes such as damage of joint cartilage tissue, thickening of the subchondral bone, osteophyte formation, inflammation of synovium at different levels, degeneration of ligaments and meniscal structures and hypertrophy of joint capsule. In recent years, studies that relate chronic pain to neuroplasticity have demonstrated changes in the structure, function and somatotopic organization of the primary motor and sensory cortex of osteoarthritis patients with chronic pain. In addition to this, osteoarthritis studies showed that the pain does not originate solely from joint problems; the central nervous system is also responsible for the formation of pain sensation. Changes in the cortical sensorimotor areas include sensory disturbances, perceptual problems (differentiation of body image), and motor influences, and these changes are associated with severity and duration of pain. When the central nervous system targeted, pain may decrease better. Action observation therapy is a method which activates mirror neurons.

In this project, investigators aim to investigate the effects of action observation therapy on pain, fear of movement, functional level and brain hemodynamics in patients with knee osteoarthritis. The study is unique in that this method, which has already been used for post-surgical or motor healing, aims at long-term administration for the first time with chronic pain and objective visualization of the results. This study will create a new perspective to understand the physiology of pain, which has attracted much interest in the literature in recent years, and will shed light on the studies that can be done in this regard.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Brain Hemodynamics

    Functional near infrared spectroscopy will be used to assess the brain hemodynamics during the observation of actions, motor imagery and active movement.

    Measured: 6 weeks

  2. Pressure pain threshold

    Algometer (dolorimeter) will be used to assess the pressure pain threshold.

    Measured: 6 weeks

  3. Visual Analog Scale

    Self reported pain intensity during rest and walking measured by 0-10 point scale.

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Action observation therapy and Exercise in people with Pain, Chronic and Osteoarthritis, Knee, run by Acibadem University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Brain Hemodynamics (time frame: 6 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2020.
