<u>Description:</u>  
The Rivermead Mobility Index consists of 15 items (14 self reported items and 1 direct observation)<ref name=":0" />. The items are scored 0 if the patient is is not able to complete the task or 1 if they are able to complete it. The points are then added together, to score a maximum of 15, with higher scores stipulating better functional mobility<ref>Shirley Ryan Ability Lab. Rivermead Mobility Index. Available from: https://www.sralab.org/rehabilitation-measures/rivermead-mobility-index (Accessed 23/06/2022)</ref>.


*The Rivermead Mobility Index is appropriate for a range of disabilities that include anything from being bedridden to being able to run
The items are<ref>Donato S, Halliday Pulaski K, Gillen G. [https://www.sciencedirect.com/science/article/pii/B9780323172813000198 Chapter 19 - Overview of Balance Impairments: Functional Implications]. In: Gillen G. Stroke Rehabilitation (Fourth Edition) Mosby, 2016. p394-415.</ref>:


15 items:  
<nowiki>1. Turning over in bed: Do you turn over from your back to your side without help?</nowiki>


*14-self-reported items
<nowiki>2. Lying to sitting: From lying in bed, do you get up to sit on the edge of the bed on your own?</nowiki>
*1 direct observation item
*Items progress in difficulty
*Items are coded as either 0 or 1, depending on whether the patient can complete the task according to specific instructions
*Items receive a score of 0 for a "No" response and 1 for a "Yes" response
*Total scores are determined by summing the points for all items
*A maximum of 15 points is possible; higher scores indicate better mobility performance
*A score of "0" indicates an inability to perform any of the activities on the measure

Objective[edit | edit source]

Gait rehabilitation.png

The Rivermead Mobility Index assesses functional mobility in gait, balance and transfers. It was developed in 1991 to be used after stroke or head injury[1].

Intended Population[edit | edit source]

Those with a diagnosis of Stroke, Acquired Brain Injury, Lower Limb Amputation or Multiple Sclerosis[2][3]. It can be used for a wide range of functional ability levels.

Method of Use[edit | edit source]

The Rivermead Mobility Index consists of 15 items (14 self reported items and 1 direct observation)[1]. The items are scored 0 if the patient is is not able to complete the task or 1 if they are able to complete it. The points are then added together, to score a maximum of 15, with higher scores stipulating better functional mobility[4].

The items are[5]:

1. Turning over in bed: Do you turn over from your back to your side without help?

2. Lying to sitting: From lying in bed, do you get up to sit on the edge of the bed on your own?

3. Sitting balance: Do you sit on the edge of the bed without holding on for 10 seconds?

4. Sitting to standing: Do you stand up from any chair in less than 15 seconds and stand there for 15 seconds, using hands and/or an aid, if necessary?

5. Standing unsupported: Ask client to stand without aid and observe standing for 10 seconds without any aid.

6. Transfer: Do you manage to move from bed to chair and back without any help?

7. Walking inside (with an aid if necessary): Do you walk 10 meters, with an aid if necessary, but with no standby help?

8. Stairs: Do you manage a flight of stairs without help?

9. Walking outside (even ground): Do you walk around outside, on pavements, without help?

10. Walking inside, with no aid: Do you walk 10 meters inside, with no caliper, splint, or other aid (including furniture or walls) without help?

11. Picking up off floor: Do you manage to walk 5 meters, pick something up from the floor, and then walk back without help?

12. Walking outside (uneven ground): Do you walk over uneven ground (grass, gravel, snow, ice, etc.) without help?

13. Bathing: Do you get into/out of a bath or shower to wash yourself unsupervised and without help?

14. Up and down four steps: Do you manage to go up and down four steps with no rail but using an aid if necessary?

15. Running: Do you run 10 meters without limping in 4 seconds (fast walk, not limping, is acceptable)?

Evidence[edit | edit source]

Reliability[edit | edit source]

Test-retest reliability

Excellent for chronic stroke and lower limb amputees[6][7][3].

Interrater reliability

Excellent for acute stroke[8][9].

Intra-rater reliability

Excellent for acute stroke[8].

Internal consistency

Good in mixed neurological population[10].

Validity[edit | edit source]

Criterion Validity:

Found in acute stroke to have excellent predictive validity with Barthel Index and scores above 4 to be the best predictor of early discharge home[11].

Adequate concurrent validity with the timed walk test for lower limb amputees[3].

Construct Validity: 

Excellent correlation with Barthel Index at 14, 30, 90 and 180 days post stroke[9].

Excellent correlation with motFIM and Timed Walk Test at the end of prosthetic training for lower limb amputees[12].

Content Validity:

The Rivermead Mobility Index achieved reproducibility and scalability  [13]. It has good content validity and was significantly correlated with physical function variables in stroke patients[6] [14]. Moreover, it is also recommended for assessing ambulation levels in chronic stroke patients during rehabilitation.[15]

Predictive Validity: 

Adequate predictive validity in stroke patients[6].

Responsiveness[edit | edit source]

The Rivermead Mobility Index was found to be one of the most sensitive outcomes measures for detecting improvements in mobility in MS patients[16]. In acute stroke patients, it was found to be valid and sensitive to change over time[6][13].
