July 14, 2023 updated by: Mohamed Magdy ElMeligie, Ahram Canadian University

Associations Between Psychological Factors, Pain Sensitivity, and Physical Function in Knee Osteoarthritis: a One-year Follow up Study

This study aims to determine if baseline measures of psychology and pain sensitivity can predict changes in physical function at 1 year in patients with knee osteoarthritis.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with clinical knee osteoarthritis experiencing persistent knee pain.

Description

Inclusion Criteria:

  • Physician diagnosis of knee OA based on clinical and radiographic ACR criteria
  • Pain in or around the knee on most days of the past month
  • Aged 40 years or above
  • Ambulatory with or without walking aid

Exclusion Criteria:

  • Inflammatory arthritis (rheumatoid arthritis, lupus, etc.)
  • Recent knee injury or surgery (past 3 months)
  • Severe comorbidity likely to prevent study completion (dementia, terminal illness)
  • inability to comply with study procedures or follow up

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Knee Osteoarthritis
Patients with physician-diagnosed knee osteoarthritis
Diagnostic test: WOMAC pain subscale

The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Subscale is a self-reported questionnaire that is used to measure pain in people with osteoarthritis (OA). The subscale consists of five items that ask about the intensity, frequency, and duration of pain in the hip and knee joints.

The WOMAC Pain Subscale has been shown to be a reliable and valid measure of pain in people with OA. It has been used in a number of clinical trials and is considered to be a standard measure of pain in OA.

The WOMAC Pain Subscale is scored on a scale of 0 to 4, with 0 indicating no pain and 4 indicating severe pain. The total score for the subscale is the sum of the scores for the five items. A higher score indicates more pain.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Physical Function from Baseline to 1 year (WOMAC)
Time Frame: Change from baseline at 1 year
Assessed using the WOMAC physical function subscale (0-68 scale, higher = worse function)
Change from baseline at 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain Catastrophizing Scale
Time Frame: Change from baseline at 1 year
Assessed using the Pain Catastrophizing Scale (0-52 scale, higher = higher catastrophizing)
Change from baseline at 1 year
Kinesiophobia
Time Frame: Change from baseline at 1 year
Assessed using the Tampa Scale of Kinesiophobia (17-68 scale, higher = higher kinesiophobia)
Change from baseline at 1 year
Change in Sleep Quality from Baseline to 1 year (Pittsburgh Sleep Quality Index)
Time Frame: Change from baseline at 1 year
Assessed using the Pittsburgh Sleep Quality Index (0-21 scale, higher = worse sleep quality)
Change from baseline at 1 year
Change in Pain Self-efficacy from Baseline to 1 year (Pain Self-Efficacy Questionnaire)
Time Frame: Change from baseline at 1 year
Assessed using the Pain Self-Efficacy Questionnaire (0-60 scale, higher = stronger self-efficacy beliefs)
Change from baseline at 1 year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 15, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
July 15, 2024

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
