- originally developed to measure mobility for patients with acquired brain injury.
- evaluates patients’ bed mobility, postural transfers, and walking ability.
- covers a range of activities, from turning over in bed to running.
Activity – subcategory: Mobility.
Number of Items:
15-item scale: 14 questions and one direct observation
Brief Instructions for Administration & Scoring
- Combined self-report and performance-based format.
- The RMI is quick to administer (approximately 3-5 minutes).
- Item 5 requires the patient to stand for 10 seconds without any aid; if the subject can stand for 10 seconds, a response of ‘yes’(1) is indicated.
- The other questions require the patient to respond either yes (scored 1) or no (scored 0).
- Scores for the 15 items are summed.
MCID: not established
SEM: not established for the SCI population, but for a chronic stroke sample (N=50, mean (SD) age: 60.9 (12.8) yrs, Taiwanese sample):
SRD = 2.2

MDC: not established
- The range of scores is between 0 (poor mobility) and 15 (good mobility).
- No information is available regarding norms or meaningful cut scores for SCI population
- Published data for the SCI population is available for comparison (see Interpretability section of the Study Details sheet
English, Dutch, Chinese and Italian.
- The RMI is simple and quick to complete making it easy to perform in the home, institutional or office settings. There is minimal patient or clinician burden.
- The 14 interview questions should be fairly quick and easy to administer but the direct observation item requiring the patient to stand without aid may not be appropriate to individuals with an SCI. Additionally, since the RMI was originally developed to measure mobility for patients with acquired brain injury, self-report items in the measure may not be applicable to individuals with an SCI.
Measurement Property Summary
# of studies reporting psychometric properties: 2
No values were reported for the reliability of the RMI for the SCI population.
- Correlation of the RMI is High with:
- the Walking Index for Spinal Cord Injury (WISCI) (Spearman’s r=0.67)
- the Spinal Cord Independence Measure (SCIM) (Spearman’s r=0.75)
- the Functional Independence Measure (FIM) (Spearman’s r=0.9)
- the Barthel Index (BI) (Spearman’s r=0.60).
[Morganti et al. 2005]
No values were reported for the responsiveness of the RMI for the SCI population.
No values were reported for the presence of floor/ceiling effects in the RMI for the SCI population.
