Items:
The RMA consists of test items in three sections that are ordered hierarchically, that is, the first items are easier and become increasingly more difficult toward the end of the evaluation.
The three sections test:
e.g. walking with and without out an aid, negotiating stairs with and without the rail, walking, turning and retrieving an object, and running
e.g. standing on one leg and flexing the knee in a weight bearing position
e.g. control items such as pronating/supinating the forearm and bouncing a ball, and functional items such as cutting putty, grasping and releasing objects, and tying a bow
The items are scored as pass or fail. Traditionally, when three consecutive attempts to complete an item are failed within a given subsection, the test is stopped as it is assumed that all subsequent items in the subsection will also be failed, so not all items in the section need to be administered (known as 'Guttman scaling'). However, recent studies suggest that the hierarchical ordering of the items in all three subscales differ from that proposed by the developers (Adams, Ashburn, Pickering & Taylor, 1997; Adams Pickering, Ashburn & Lincoln, 1997; Kurtais et al., 2009) and as a result, it has been recommended that all items in each of the subscales be administered. In an effort to avoid over-burdening patients and to reduce administration time, the ceiling effect of three consecutive failures should be applied (Kurtais et al., 2009).
For patients with an additional disability, for example, an amputation, the principle of stopping after 3 consecutive errors should not be applied (Lincoln & Leadbitter, 1979).
As an example of the RMA items and Guttman scaling, below are the items for the Gross Function subscale of the RMA.
Can the patient:
1. Sit unsupported (without holding on edge of bed feet unsupported)
2. Transfer from lying to sitting on side of bed (using any method)
3. Transfer from sitting to standing
4. Transfer from wheelchair to chair towards unaffected side (may use hands)
5. Transfer from wheelchair to chair towards affected side (may use hands)
6. Walk 10 meters indoors with an aid (any walking aid, no standby help)
7. Climb flight of stairs independently (any method, may use banister and aid)
8. Walk 10 meters indoors without an aid (no standby help or walking aid)
9. Walk 10 meters, pick up beanbag from floor, turn and carry back (may use aid to walk)
10. Walk outside 40 meters (may use walking aid, no standby help)
11. Walk up and down 4 steps (may use any aid but may not hold on to railing)
12. Run 10 meters (must be symmetrical)
13. Hop on affected leg 5 times on the spot (must hop on ball of foot without stopping to regain balance, no help with arms)
Scoring:
Each item on the RMA is coded 0 or 1, depending on whether the client does the activity according to specific instructions. A score of 0 = a 'no' response; a score of 1 = a 'yes' response. Each subscale is scored by summing the points allocated for all items within that subscale.
If a patient refuses to perform an item (e.g. out of anxiety), score a '0' for that item.
Time:
The ambulatory client with a recovering upper extremity takes approximately 45 minutes to assess; more severely disabled patients take less time (Lincoln & Leadbitter, 1979).
Subscales:
The RMA has three subscales: Upper Limb/Extremity ('Arm'); Lower Limb/Extremity ('Leg') and Trunk; Gross Function.

Training:
No specialized training is required to administer the RMA. However, the RMA should be administered by a physiotherapist with knowledge on how to safely manage those with stroke. The RMA is a risky assessment where a patient could fall if not supervised by someone with stroke expertise.
