Table 4.
Dual-task interference patterns in people who sustained a stroke according to the categorization of the nature of the locomotor and cognitive tasks.
| Locomotor tasks | Cognitive task | Mutual interference | Cognitive-related motor interference | Motor-related cognitive interference | No dual-task interference |
|---|---|---|---|---|---|
| Forward walking | Mental tracking tasks (n = 5) | n = 2 (25, 31) | n = 2 (35, 36) | n = 1 (34) | n = 0 |
| Discrimination and decision -making tasks (n = 2) | n = 2 (31, 40) | n = 0 | n = 0 | n = 0 | |
| Verbal fluency tasks (n = 1) | n = 0 | n = 0 | n = 1 (34) | n = 0 | |
| Working memory task (n = 1) | n = 1 (28) | n = 0 | n = 0 | n = 0 | |
| Reaction time task (n = 2) | n = 1 (31) | n = 0 | n =1 (33) | n = 0 | |
| Walking with direction changes | Mental tracking tasks (n = 4) | n = 1 (30) | n = 3 (27, 41) | n = 1 (27) | n = 1 (27) |
