|What does the tool measure?||The RMI measures mobility disability in clients with stroke|
|What types of clients can the tool be used for?||Clients with stroke, head injury or multiple sclerosis.|
|Is this a screening or assessment tool?||Assessment|
|Time to administer||An average of 3 to 5 minutes.|
|Versions||Modified Rivermead Mobility Index.|
|Other Languages||Italian and Dutch.|
|Reliability||– Two studies examined the internal consistency of the RMI and reported excellent internal consistency using Chronbach’s alpha and reliability coefficient rho.
– Three studies have examined the test-retest reliability of the RMI and reported adequate to excellent test-retest reliability using Intraclass Correlation Coefficient (ICC) and Kappa Statistics.
– One study, using Rasch Analysis reported that item difficulty on the RMI is the same across repeated measures.
– Two studies examined the inter-rater reliability of the RMI and reported poor to excellent inter-rater reliability using Bland and Altman Technique, ICC and weighted Kappa.
|Floor/Ceiling Effects||Two studies examined the floor and ceiling effects of the RMI and reported that at earlier phases of the stroke, floor effects were poor. When the RMI is measured 180 days after stroke ceiling effects were adequate.|
|Does the tool detect change in patients?||Three studies have examined the responsiveness of the RMI and reported that the RMI has a large Standardized Response Mean, a large effect size and is able to detect minimal clinically important differences in clients with stroke.|
|Acceptability||The RMI should not be administered to clients with severe cognitive impairments due to the 14 self-reported items.|
|Feasibility||The administration of the RMI is quick and simple.|
|How to obtain the tool?||The RMI can be obtained from the studies by Antonucci et al. (2002), Forlander & Bohannon (1998) or Franchignoni et al. (2003).|
