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.

Detailed Description

Reduced lumbar mobility has been associated with various musculoskeletal alterations, including low back pain, changes in movement patterns, and increased risk of spinal disorders. Lumbar range of motion is considered a crucial parameter in determining disability for compensation claims and litigation worldwide.

The Modified-Modified Schober Test (MMST) is a widely used clinical tool for assessing lumbar range of motion, particularly flexion. This test utilizes the posterior superior iliac spines (PSIS) as the lower anatomical landmark and a point 15 cm above as the upper landmark, measuring the increase in distance during forward flexion.

Despite some limitations, the MMST remains a recommended clinical tool due to its simplicity and established reliability.

Regarding extensibility measurement, recent research has demonstrated that Kinovea software exhibits excellent intra-rater reliability, excellent inter-rater reliability, and strong criterion validity for measuring hamstring extensibility using the sit and reach test when compared to traditional tape measurements.

Therefore, this study aims to fill this research gap by measuring the validity & reliability of Kinovea software program in measuring lumbar extensibility using the Modified-Modified Schober Test by examining the psychometric properties of Kinovea for lumbar spine assessment as the kinovea software is low cost, provide more accurate data and easy to use.

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

Accepts Healthy Volunteers

Yes

Sampling Method

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
Validity of Kinovea Software Measurement
Time Frame: 1 year
To evaluate criterion validity the trials of Modified-Modified Schober test will be concurrently captured by a video camera. Each video underwent downloading onto a computer, followed by analysis using Kinovea software and correlating the results of Modified-Modified Schober Test with those of the kinovea software.
1 year
Intra-rater reliability of Kinovea Software Measurement
Time Frame: 1 year
To evaluate Intra-rater reliability, the 1st examiner will analyze the video that will be recorded at the 1st assessment and 1 week later using kinovea and the results will be compared.
1 year
Inter-rater reliability of Kinovea Software Measurement
Time Frame: 1 year
To evaluate Inter-rater reliability, 1st and 2nd examiner will analyze the video recorded in the 1st assessment using kinovea and the results will be compared.
