Walking Tests: Tracking Multiple Sclerosis Progression

Why Walking Tests Matter

Multiple sclerosis (MS) causes the immune system to attack the protective coating of nerves, leading to a wide range of symptoms. Because the disease can progress silently, doctors use walking tests to monitor mobility, gauge disability, and evaluate treatment effectiveness.

Walking integrates vision, sensation, strength, coordination, and balance, making it a sensitive indicator of overall neurological function. A slower gait often predicts long‑term mobility limitations.

How Tests Are Conducted

During a walking test you cover a set distance—usually 6, 10, or 25 feet—while the clinician times the effort. You may use a cane, walker, or other assistive device, and the level of assistance is recorded (none, minimal, or moderate).

The clinician compares your speed to age‑matched norms and to your previous results, helping decide whether your current therapy is working or needs adjustment.

Common Walking Tests

10‑Meter Walk Test

Walk 10 meters (≈32 feet) as quickly and safely as possible. The time taken reflects functional mobility and gait quality. This test is also used for Parkinson’s disease, stroke, and spinal‑cord injury assessments.

25‑Foot Timed Walk (T25FW)

Walk 25 feet as fast as you can, with or without an assistive device. Timing starts on the first step and stops when the foot reaches the 25‑foot mark. The T25FW is a component of the Multiple Sclerosis Functional Composite (MSFC) and helps track disease progression.

6‑Meter Walk Test

Similar to the 10‑meter test but over a shorter distance, making it practical for small clinics or home‑health settings. A 2014 study found it useful when space is limited.

12‑Item Multiple Sclerosis Walking Scale (MSWS‑12)

This self‑report questionnaire asks how MS affects speed, stair climbing, balance, use of supports, and overall walking effort. Each response is scored, producing an overall index of walking disability.

Interpreting Results

Consistent testing with the same protocol allows clinicians to detect subtle changes over time. A decline may signal the need for therapy modification, supplemental disability insurance, or occupational adjustments. Conversely, improved times can indicate successful disease‑modifying treatment.

Limitations and Complementary Assessments

Walking speed can be influenced by age, comorbid conditions (e.g., arthritis, chronic back pain), and the type of assistive device used. Therefore, clinicians also evaluate vision, strength, sensation, and coordination separately, and consider the Expanded Disability Status Scale (EDSS) and other functional measures.

Practical Considerations

• Tests take less than 10 minutes and are usually covered by health insurance.
• They are inexpensive, easy to administer, and provide a clear snapshot of mobility.
• Home‑based self‑testing is not a substitute for a clinician‑performed assessment.

Bottom Line

Walking tests are a valuable, low‑cost tool for monitoring MS progression and treatment response. Regular, doctor‑administered assessments—combined with comprehensive neurological exams—help you and your care team stay ahead of the disease.
