Clinical Trial Summary

Apraxia and action disorganization syndrome after stroke can disrupt activities of daily living (ADL). Occupational therapy has been effective in improving ADL performance, however, inclusion of multiple tasks means it is unclear which therapy elements contribute to improvement. This study evaluates the efficacy of a task model approach to ADL rehabilitation, comparing training in making a cup of tea with a gait training control condition.

Description:

Apraxia and action disorganization syndrome (AADS) after stroke can disrupt activities of daily living (ADLs). Occupational therapy has been effective in improving ADL performance, however, inclusion of multiple tasks means it is unclear which therapy elements contribute to improvement.

This trial evaluates the efficacy of a task model approach to ADL rehabilitation, comparing training in making a cup of tea with a stepping training control condition.

Stroke survivors with AADS participate in a cross-over randomized controlled study. Participants attend five 1-hour tea making training sessions in which progress is monitored and feedback given using a computer-based system which implements a Markov Decision Process (MDP) task model (CogWatch). In a control condition participants receive five 1-hour stepping sessions.

Analysis compares tea making training with stepping training effects on error reduction and time taken in making 4 different tea types. A complex tea preparation task (making two different cups of tea simultaneously) is used to test for generalisation of training effects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in tea making accuracy	In three assessment sessions (initial, post-phase 1 training, post-phase 2 training), participants are seated at a table with objects and ingredients required for making a cup of tea placed in standard positions. Participants are instructed to make 8 cups of tea, one at a time, comprising two of each of the following; black tea, black tea with sugar, tea with milk and tea with milk and sugar. Each trial is recorded with a video camera.; Videos of the participants making simple tea are analysed by a researcher blinded to the session definition. The summed errors across the 8 tea making trials at each assessment are used to provide a measure of accuracy for each participant.; Change in tea making accuracy pre- and post-training of tea making is contrasted with change in tea making accuracy pre- and post-training of stepping.	3 assessments over 12 weeks
Primary	Change in tea making speed	In three assessment sessions (initial, post-phase 1 training, post-phase 2 training), participants are seated at a table with objects and ingredients required for making a cup of tea placed in standard positions. Participants are instructed to make 8 cups of tea, one at a time, comprising two of each of the following; black tea, black tea with sugar, tea with milk and tea with milk and sugar. Each trial is recorded with a video camera.; Videos of the participants making simple tea are analysed by a researcher blinded to the session definition. The average completion time is used as a measure of speed for each participant.; Change in tea making speed pre- and post-training of tea making is contrasted with change in tea making speed pre- and post-training of stepping.	3 assessments over 12 weeks
Secondary	Tea making accuracy at follow-up	In a fourth, follow-up assessment session (7 or 15 weeks post-tea making training), participants are seated at a table with objects and ingredients required for making a cup of tea placed in standard positions. Participants are instructed to make 8 cups of tea, one at a time, comprising two of each of the following; black tea, black tea with sugar, tea with milk and tea with milk and sugar. Each trial is recorded with a video camera.; Videos of the participants making simple tea are analysed by a researcher blinded to the session definition. The summed errors across the 8 tea making trials at each assessment are used to provide a measure of accuracy for each participant.; Tea making accuracy at follow-up is compared with tea making accuracy post-training of tea making.	2 assessments over 15 weeks
Secondary	Change in complex tea making accuracy	In three assessment sessions (initial, post-phase 1 training, post-phase 2 training), participants are seated at a table with objects and ingredients required for making two cups of tea placed in standard positions. Participants are instructed to make 4 cups of tea, two at a time, comprising one cup with tea, lemon and 1 sugar cube and the other with tea, milk and 2 sweeteners. Each trial is recorded with a video camera.; Videos of the participants making complex tea are analysed by a researcher blinded to the session definition. The summed errors across the 4 tea making trials at each assessment are used to provide a measure of accuracy for each participant.; Change in complex tea making accuracy pre- and post-training of tea making is contrasted with change in complex tea making accuracy pre- and post-training of stepping.	3 assessments over 12 weeks
