Purpose

The 10-Meter Walk Test (10MWT) is designed to evaluate an individual's walking speed, measured in meters per second, within a brief duration.

 

Acronym

10MWT (10-Meter Walk Test)

Evaluated Areas

The 10MWT primarily assesses functional mobility, gait analysis, and vestibular functions.

Use

It serves as a performance measure, quantifying walking speed and mobility capabilities.

Tools required

This assessment is conducted traditionally using paper and pencil methodology.

Cost

Access to the 10 metre walk test is available at no charge, ensuring widespread availability and utilization.

Diagnosis/Conditions

The 10mwt is applicable across various conditions and diagnoses, including brain injury recovery, limb loss, multiple sclerosis, Parkinson's disease, neurologic rehabilitation, spinal cord injury, and stroke recovery.

Scoring

The duration taken to ambulate precisely 6 meters is meticulously recorded to the nearest hundredth of a second. To calculate the gait speed, the distance (6 m) is then divided by the total time taken in seconds, providing the result in meters per second.

7-ordinal point scale

The scale for assessing physical assistance utilizes a structured 7-point system, delineated as follows:

1. Total Assistance: Patient accomplishes 0%-24% of the task.

2. Maximum Assistance: Patient performs 25%-49% of the task.

3. Moderate Assistance: Patient executes 50%-74% of the task.

4. Minimum Assistance: Patient manages 75%-99% of the task.

5. Supervision: Patient requires standby assistance without physical contact.

6. Modified Independence: Patient utilizes assistive devices, requires extra time, and may have mild safety concerns.

7. Independent: Patient completes the task without assistance.

 

*Note: In instances where the patient necessitates total assistance, a score of 0 is recorded for documentation purposes.

 

Normative Values for Healthy Adults

Age Groups and Gait Speed (in meters per second)

 

Age Group	Men (m/s)	Women (m/s)
20s	1.358	1.341
30s	1.433	1.337
40s	1.434	1.390
50s	1.433	1.313
60s	1.339	1.241
70s	1.262	1.132
80s/90s	0.968	0.943

 

These values represent normative gait speed data for healthy adults across different age groups. Tracking gait speed against these averages aids in assessing mobility and potential changes in functional capacity among individuals.

Performing the 10 Meter Walk Test (10MWT)

Introduction

The 10MWT is a rapid assessment providing crucial insights into a patient's gait speed, aiding in patient education, outcomes evaluation, and prognosis determination.

Materials Needed:

Distance Markers:Measure and mark a 10-meter distance, placing markers at each end. Additionally, mark points at 2, 8, and 10 meters.

Timing Device:Utilize a stopwatch or a phone with a stopwatch feature.

1. Test Procedure:

Preparation: Instruct the patient regarding the test's nature:

Comfortable Pace:"Walk at your normal, comfortable speed."

Fast Pace:"Move at a pace that's both safe and brisk for you."

2. Execution:

 Begin timing when the patient's leading foot crosses the 2-meter mark.

 Stop timing when the leading foot crosses the 8-meter mark.

 Ensure consistency in any assistive devices used.

Refrain from providing any assistance to the individual throughout the examination.

3. Trials and Averages:

   Conduct three trials and calculate the average time for accuracy.

4. Calculating Gait Speed:

  Divide the distance covered by the time taken.

  For instance, if a patient takes 9 seconds to cover 6 meters, divide 6 by 9 to calculate gait speed in meters per second (e.g., 0.67 m/s).

Considerations:

Trials:Multiple trials provide a more accurate assessment.

Documentation:Record assistive devices used and patient instructions.

Assistance:Avoid aiding the patient during the test for accurate results.

Clinical Application:

The calculated gait speed serves as a standard metric for clinical assessment, aiding in gauging the patient's mobility and potentially guiding treatment decisions.

 

Clinical significance of 10 metre walk test

The clinical significance of the 10-Meter Walk Test (10MWT) lies in its ability to serve as a practical and reliable tool for assessing an individual's functional mobility, specifically their walking speed.

 Functional Mobility Evaluation:

Objective Measurement: Offers a quantitative measure of a patient's walking speed, aiding in the evaluation of mobility limitations.

Monitoring Progress: Tracks changes in walking speed over time, reflecting improvements or declines in functional mobility.

Diagnostic and Prognostic Indications:

Rehabilitation Planning: Assists in planning interventions and setting goals by identifying deficits and improvements in gait speed.

Predictive Value: Helps predict functional recovery and outcomes in various conditions, such as stroke rehabilitation or neurological disorders.

Treatment Efficacy Assessment:

Outcome Measurement: Serves as an outcome measure to assess the effectiveness of interventions, treatments, or therapeutic approaches targeting mobility.

Clinical Decision-Making:

Clinical Decision Support: Provides clinicians with crucial information for making informed decisions about treatment strategies, patient care plans, and potential assistive devices needed for improved mobility.

Comparative Analysis:

Normative Data Comparison: Facilitates comparison of an individual's walking speed against normative values for age-matched healthy adults, aiding in assessing their mobility status.

In summary, the 10MWT holds clinical significance by serving as a straightforward, efficient, and informative tool for evaluating, monitoring, and guiding interventions related to functional mobility and walking speed in various clinical settings.

What is MDC, SEM, Reliability and MCID?

MDC, SEM, reliability, and MCID are key statistical measures used in clinical assessments to understand the precision, consistency, and meaningful change in measurements:

1. MDC (Minimal Detectable Change)

Definition: MDC represents the smallest change that indicates a true, clinically relevant change in a measurement beyond random variability or measurement error.

  Significance: If the observed change exceeds the MDC, it's considered beyond measurement error and thus represents a real change.

  Example: In gait speed assessments, if the change in speed surpasses the MDC, it indicates a genuine improvement or decline in walking ability.

 

2. SEM (Standard Error of Measurement)

 Definition: SEM quantifies the precision or accuracy of a measurement by estimating the variability expected between repeated measures within the same individual.

 Significance: It provides an indication of how close repeated measurements are likely to be to the true score.

  Example: A SEM of 0.1 m/s for gait speed means that individual gait speed measurements might deviate from their true value by up to 0.1 m/s due to measurement error.

 

3. Reliability

  Definition: Reliability refers to the consistency, stability, or reproducibility of measurements obtained under consistent conditions.

  Significance: It indicates the extent to which a measurement tool produces consistent results over repeated trials or assessments.

   Example: A reliability coefficient (like ICC - Intraclass Correlation Coefficient) of 0.9 or higher suggests high reliability, indicating strong consistency in the measurements obtained.

 

4. MCID (Minimally Clinically Important Difference)

  Definition: MCID represents the smallest change in a measurement that is considered clinically meaningful or significant.

  Significance: It helps clinicians understand what change in a patient's condition is noticeable and important from a clinical perspective.

  Example: For gait speed, an MCID of 0.1 m/s might signify the minimum change in walking speed that patients perceive as meaningful in their daily activities.

 

These measures collectively aid in interpreting the significance, precision, and clinical relevance of changes observed in various assessments, such as gait speed, mobility, and functional capacity, across different medical conditions.

 

In conclusion, the 10 Meter Walk Test (10MWT) stands as a pivotal tool in clinical assessment, offering valuable insights into an individual's mobility and functional capacity.
