- Disease Steps serves as a guide for neurologists in the decision of when to intervene therapeutically and also to observe the patient’s response over time. Classification is based on ambulation status as well as a history of neurologic examination.
- The ambulation scale, walking 25 feet, consists of:
0 = Functionally normal with no limitations on activity or lifestyle
1 = Mild disability, mild symptoms or signs
2 = Moderate disability, visible abnormality of gait
3 = Early cane, use of a cane or other form of unilateral support for greater distances, but can walk at least 25 feet without it
4 = Late cane, cane dependent, unable to walk 25 feet without a cane or other form of unilateral support
5 = Bilateral support, requires bilateral support to walk 25 feet
6 = Confined to wheelchair
U = Unclassifiable, used for patients who do not fit above classification
- The neurological exam performed requires client participation that establishes scores 1-2.
- 25-foot unobstructed walkway

Professional Association Recommendation
Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Considerations
Disease Steps is heavily weighted towards ambulation. Unclassifiable patients include individuals with severe visual impairment, overwhelming fatigue, significant bowel or bladder involvement, or severe cognitive impairment in patients with otherwise minor physical disability.
Disease Steps may be more sensitive for patients who use unilateral support.
May not capture acute attacks and does not incorporate measures of disease activity such as attack frequency.
May not be for a skilled nursing facility as a majority of patients there would be a 6 on the scale.
Scale is specific to MS and strongly correlates with the EDSS gold standard.
Recommended for EDSS 0.0-9.5.
Recommended for entry-level curricula.
Not recommended for research purposes; possible limited objectivity with the scale. More objective scales include Timed 25’ Walk, 2- or 6-minute Walk, or 5 Times Sit to Stand.
