Table 2 The standardized DT GR protocol

From: Dual-task versus single-task gait rehabilitation after stroke: the protocol of the cognitive-motor synergy multicenter, randomized, controlled superiority trial (SYNCOMOT)

Progression

Five types of 5-min gait exercise (30 min per session, 3 times a week (on days (D)1, D2, and D3)

Level of motor difficulty

Level of cognitive difficulty

Week 1

- Walking during an executive function task: go/no-go letters (D1: letter “A,” D2: letter “B,” D3: letter “Z”)

- Walking during a memory task: minus -2 span

- Walking while holding an object in the healthy hand: a half-full glass of water

- Walking during a semantic fluency task (D1 animals, D2 fruits, D3 supermarket articles)

- Walking during while looking for targets in the space ahead (D1 objects, D2 images, D3 words)

1/ Comfortable walking

2/ Walking with weights (100–250 g)

3/ Walking along a line

1/ A quiet environment

2/ Music selected by the patient

3/ News radio (France Info)

If an exercise is impossible, replace it with a calculation (plus 2) and the following starting numbers: 0, 1, 14, 43, 128 (5 × 1 min). If this is impossible, count backwards or forwards, depending on the patient's abilities.

Week 2

- Walking during an executive function task: go/no-go Letters (D1: letter “A,” D2: letter “B,” D3: letter “Z”)

- Walking during a memory task: minus −1 span

- Walking while holding an object in the healthy hand: a 75%-full glass of water

- Walking during a semantic fluency task (D1 kinds of bird, D2 towns, D3 colors)

- Walking during while looking for targets on the healthy side (D1 objects, D2 images, D3 words)

4/ Comfortable walking with weights (100–250 g)

5/ Comfortable walking with weights (250–500 g)

6/ Comfortable walking and crossing obstacles <5 cm in height

1/ A quiet environment

2/ Music selected by the patient

3/ News radio (France Info)

If an exercise is impossible, replace it with a calculation (plus 3) and the following starting numbers: 0, 1, 14, 43, 128 (5 × 1 min). If this is impossible, count backwards or forwards, depending on the patient's abilities.

Week 3

- Walking during an executive function task: go/no-go numbers

- Walking during a memory task: minus −2 alphabetic span

- Walking while holding an object in the paretic hand: a half-full glass of water

- Walking during an alternating semantic fluency task (D1 animals/fruits, D2 fruits/vegetables, D3 fruits/supermarket articles)

- Walking while looking for targets on the paretic side (D1 objects, D2 images, D3 words)

7/ Fast walking

8/ Fast walking with weights (100–250 g)

9/ Fast walking on a foam carpet

1/ A quiet environment

2/ Music selected by the patient

3/ News radio (France Info)

If an exercise is impossible, replace it with a calculation (minus 2) and the following starting numbers: 0, 1, 14, 43, 128 (5 × 1 min). If this is impossible, count backwards or forwards, depending on the patient's abilities.

Week 4

- Walking during an executive function task: go/no-go numbers

- Walking during a memory task: minus −1 alphabetic span

- Walking while holding an object in the paretic hand: a 75%-full glass of water

- Walking during an alternating semantic fluency task (D1 kinds of fish/bird, D2 fruits/towns, D3 colors/furniture

- Walking while looking for targets in the space behind (D1 objects, D2 images, D3 words)

10/ Fast walking with weights (100–250 g)

11/ Fast walking with weights (250–500 g)

12/ Fast walking and crossing obstacles <10 cm in height

1/ Quiet environment

2/ Music selected by patient

3/ News radio (France Info)

If an exercise is impossible, replace it with a calculation (minus 3) and the following starting numbers: 0, 1, 14, 43, 128 (5 × 1 min). If this is impossible, count backwards or forwards, depending on the patient's abilities.
