CTCAE Grading of Walking Difficulty:
Grade 1: Mild change in gait (e.g., wide-based, limping, or hobbling)
Grade 2: Moderate change in gait (e.g., wide-based, limping, or hobbling); assistive device indicated; limiting instrumental ADLs
Grade 3: Disabling; limiting self-care ADLs
Characterize the symptom (onset, pace)
Ask the patient:
Have you had any issue with walking in the past? Is this a new or worsening symptom? When did it start or get worse? Has it developed gradually or suddenly?
Grade the symptom
Ask the patient:
How difficult do you find it to walk? Are you able to walk unaided or do you need a cane/walker? Are you able to do the things you want to do and take care of yourself?
Ask the patient:
Do you have any difficulty breathing? Have you fallen?
Consider the following in individualizing the intervention: Is the patient a good or poor historian? Any language barriers or cognitive deficits? Is the patient reliable (able to carry out treatment recommendations)? Does this patient have alcohol/substance abuse issues? Does the patient have transportation? Is there sufficient caregiver support?
Patients with new onset moderate or worse (or worsening) walking difficulty need to be seen.
Patients with any of the red-flag symptoms should be seen immediately.
What do you suspect is the cause of difficulty walking?
