5. Person is asked to rise from sitting to standing using the arm rests of the chair. 

6. Person is asked to stand with their arms crossed over their chest.

Walking 

11. Persons will be asked to walk with their current gait aid to where they can without a rest.Testing ceases if the person stops to rest. The person uses the gait aid that is currentlymost appropriate for them. If either of two gait aids could be used, the aid that providesthe person with the highest level of independence should be used. Testing ceases oncethe person reaches 50 meters. 

12. Independence is assessed over the person’s maximum walking distance up to 50m (fromitem 11). 

Dynamic Balance 

13. A pen is placed 5 cm in front of the person’s feet in standing. The person is asked if theycan pick the pen up off the floor. 

14. Walks backwards 4 steps. Person remains steady throughout. 

15. Person can jump. Both feet clear the ground. Person remains steady throughout. 

Definitions 

Minimal assistance = “hands on” physical but minimal assistance, primarily to guide movement. 

Supervision = another person monitors the activity without providing hands on assistance. Mayinclude verbal prompting. 

Independent = the presence of another person is not considered necessary for safe mobility. 

PROTOCOL FOR ADMINISTRATION OF THE DEMMI 

1. Testing should be performed at the person’s bedside. 

2. Testing should be performed when the person has adequate medication eg. at least halfan hour after pain or Parkinson’s Disease medication. 

3. The test should be administered in the sequence described in sections A-E: bedtransfers, chair transfers, static balance, walking and dynamic balance. 

4. Each item should be explained and, if necessary, demonstrated to the person. 

5. Items should be ticked to indicate item success or failure. Reasons for not testing itemsshould be recorded. 

6. Items should not be tested if either the test administrator or the person performing thetest are reluctant to attempt the item. 

7. Persons should be scored based on their first attempt. 

8. If an item is not appropriate given a person’s medical condition, the item should not betested and the reason recorded. 

9. Persons can be encouraged but feedback should not be provided regardingperformance. 

10. Three equipment items are required: chair with 45cm seat height with arm rests, ahospital bed or plinth and a pen. 

11. The person administering the test manipulates person medical equipment during testing(eg. portable oxygen, drips, drains etc) unless the person requires minimal assistance toperform the test and then a 2nd person will be required to assist with medical equipment. 

12. For persons that require a rest after each item due to shortness of breath, a 10 minuterest should be provided half way through testing i.e. after completing the chair transferssection. 

13. For person’s who have low level mobility and require a hoist to transfer in/out of bed orchair, the chair section can be administered before the bed section for these persons. 

14. Bed transfers: the bed height should be appropriate for the individual person. Astandardised hospital bed or plinth should be used for testing. The person cannot use anexternal device such as the monkey bar, bed rail, edge of bed or a bed pole. Additionalpillows may be provided for persons who are unable to lie flat in supine. 

15. Chair transfers: A standardised chair height of 45cm is required. A firm chair with armsshould be used. 

16. Balance: Shoes cannot be worn for balance testing. The person cannot use externalsupport to successfully complete any balance items. For sitting balance, neither the armrests or the back of the chair can be used for external support. Standing balance testsshould be performed with the person positioned between an elevated bed on one sideand the test administrator on the other side. If a person displays unsteadiness orsignificant sway during testing, testing of that item should cease. 

17. Walking: Appropriate shoes can be worn for walking tests. The same shoes must beworn for repeat testing.18. Scoring: Using the conversion table provided, the raw score total must be converted to aDEMMI SCORE.
