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

45 years and older (ADULT, OLDER_ADULT)

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
stair climb test
Time Frame: 2 hours
An 11-step stairway with a step height of 17 cm will be used. Participants will begin with both feet on the bottom landing, then ascend and descend the stairway as fast as possible, and finally stop with both feet back on the bottom landing while using a handrail support, if required. Time recording will be started when the participant is signalled to start and ended when the participant returns with both feet on the ground.
2 hours
timed Up and Go test (TUG)
Time Frame: 2 hours
The participant will sit down at first and then stand up when given the signal to start. As fast as possible, the participant will walk 3 meters toward a cone on the floor, circle it, walk back 3 more meters toward a chair, and finally sat down. Timing begins on the signal to start and ends when the participant completely sits down with their back resting on the backrest of the chair.
2 hours
6-minute walk test (6MWT)
Time Frame: 2 hours
In the 6MWT, the participants will walk as far as they could within 6 minutes. They will not be allowed to carry a watch or provided feedback during the trial. Although rest periods are allowed, time recording will continue. The participants will be provided encouragement at 1-minute intervals.
2 hours
VAS(Visual Analog Scale score) for knee pain
Time Frame: 2 hours
The mean knee pain during the stair climb test, TUG test, and 6MWT will be measured using the VAS. Participants will record their level of knee pain by drawing a vertical mark between the ends of a 10-cm horizontal line. The 0-cm end and the 10-cm end represented no pain and the most extreme pain, respectively.
2 hours
The Knee injury and Osteoarthritis Outcome Score (KOOS)
Time Frame: 2 hours
The Knee injury and Osteoarthritis Outcome Score (KOOS) was developed as an extension of the WOMAC Osteoarthritis Index with the purpose of evaluating short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis. The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL).
2 hours
Perceived Competence Scale (PCS) questionnaire
Time Frame: 2 hours
The Perceived Competence Scale (PCS) concerns feelings about behaving in healthy ways. This is a short 4-item questionnaire that assesses the degree to which participants feel confident about being able to make (or maintain) a change toward a healthy behavior, participate in a health-care program, or carry out a treatment regimen/physical tests.
2 hours
The Hospital Anxiety and Depression Scale (HADS)
Time Frame: 2 hours
HADS was found to perform well in assessing the symptom severity of anxiety disorders and depression in in the general population. The sensitivity and specificity for both HADS-A and HADS-D of approximately 0.80. The questionnaire comprises seven questions for anxiety and seven questions for depression.
2 hours

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
2-step test
Time Frame: 2 hours
Gait stride length is measured to assess walking ability, including muscle strength, balance, and flexibility of the lower limbs. The starting line is determined, and participants stand with the toes of both feet behind this line. They take 2 long steps (as long as possible) and then align both their feet. Subsequently, the length of the 2 steps from the starting line to the toes is measured.
2 hours
stand-up test
Time Frame: 2 hours
The participant will stand up on 1 or both legs from a seat at a specified height. For this test, 4 seats are set up at different heights (40, 30, 20, and 10 cm). First, the participants will sit on the 40-cm high seat with arms folded. If they can stand up on both legs, they then attempt to stand on 1 leg. If they can stand up on both their right and left legs, they pass the height level. The participants then repeat the trial at the next seat height, and the trials will be performed in the order of descending height.
2 hours
Knee extensor strength
Time Frame: 2 hours
The maximum isometric knee extensor strengths will be measured using a handheld dynamometer (HHD), which is the validated method in a previous research on elderly individuals who are prone to falls.17 The maximum force will be recorded in Newtons (N), and testing will be repeated for 2 measurements.

Primary Completion (ANTICIPATED)

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.
