Lower Extremity Selective Voluntary Motor Control in Adults With Chronic Stroke: Comparing the SCALE Assessment to the Fugl-Meyer Assessment

The purpose of this study is to compare the clinometric (psychometric) properties of the SCALE and FMA-LE assessments in adults after stroke. A second purpose is to determine how well each measure predicts walking speed using the 10 meter walk test.

Detailed Description

Selective voluntary motor control may be important in prognosticating future function in adults post stroke. It is therefore important to measure selective voluntary motor control using assessments that are valid, reliable and easy to perform and interpret. Current assessments are time consuming and complicated. Clinicians who work with patients post stroke will benefit from this research because they will have evidence supporting appropriate measurement of selective voluntary motor control. This evidence may inform their clinical decision making when working with patients. Patients who have survived a stroke will benefit because their therapists will be able to better measure their selective voluntary motor control which may one day lead to better prediction of functional outcomes and the selection of appropriate interventions.

The Fugl-Meyer assessment (FMA) is the "Gold Standard" for the assessment of individuals with brain injury, most commonly those surviving cerebrovascular accident (stroke). The full assessment is complicated and can take more than an hour to complete. Clinicians have limited time to perform a full evaluation of their patients, the FMA is just one part of this evaluation. The lower extremity selective voluntary motor control component of the FMA (FMA-LE) is difficult for clinicians who are not experts to perform and interpret. For these reasons, few practicing clinicians use the FMA. However, measuring selective voluntary motor control may be important for prognosticating patients' future functional level and their need for continued therapeutic interventions. The Selective Control Assessment of Lower Extremity (SCALE) was developed for use with children who have cerebral palsy (CP), a condition that in some ways presents similar to stroke. The SCALE has been validated and deemed reliable in the pediatric population with CP. This study aims to determine inter-rater and intra-rater reliability for the FMA-LE and the SCALE. In addition, scores on the SCALE will be compared to scores on the FMA-LE to determine concurrent validity. Finally the scores on the SCALE and FMA-LE will be compared to the time it takes for stroke survivors to walk 10-meters (10-meter walk test) to determine how well each measure predicts functional status (predictive validity).

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

18 years to 79 years (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
Selective Control Assessment of Lower Extremity (SCALE)
Time Frame: Baseline to 4 weeks
Each item is rated 2-0, 2 being Normal and 0 being Unable to Move
Baseline to 4 weeks

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
Fugl-Meyer Assessment-Lower Extremity component (FMA-LE)
Time Frame: Baseline to 4 weeks

The complete Fugl-Meyer contains 155 items and each item is rated on a three-point ordinal scale, 2 points for the detail being performed completely, 1 point for the detail being partially completed, and 0 points for the detail not being performed. The maximum score for the motor performance is divided into 66 points for the upper extremity and 34 for the lower extremity. Only the lower extremity motor assessment component of the Fugl-Meyer will be used for this study, which consists of 17 items.

Fugl-Meyer Assessment (Upper and lower extremity components). Available from: https://www.researchgate.net/publ
Baseline to 4 weeks
10-meter walk test
Time Frame: Baseline to 4 weeks
Performance measure used to assess walking speed in meters per second over a short distance. It can be employed to determine functional mobility, gait, and vestibular function. Scoring is done by completing three trials and calculating the average of the three trials to obtain the velocity. The test may be completed at the subject's self-selected velocity and/or at the subject's fast velocity.
