Description of intervention(s) / exposure
DOSE-UP includes two subgroups within the trial; early in recovery (recruit participants 3 to 14 days post stroke) and late in recovery (recruit participants 3 to 9 months post stroke).

What intervention and why:
The intervention administered during the trial will be a combination of impairment and task-specific, upper limb motor training. An example of an impairment-based exercise would be repetitive practice of wrist extension whereas a task specific exercise would be repetitive practice of reaching for a cup. The rationale for this decision is based on optimal training characteristics from stroke motor learning literature, Australian National Stroke Foundation Guidelines, and previous findings from stroke recovery trials.

Who:
Please refer to Eligibility for details of participants involved in the study. The intervention will be delivered by clinicians (e.g. occupational therapist, physiotherapist, exercise physiologist) with experience and training in the established impairment and task-specific, upper limb motor training protocol.

How:
EARLY - The mode of therapy will be provided face to face in either fully supervised or semi supervised practice.
LATE - The mode of therapy will be provided face to face in either fully supervised or semi supervised practice for four out of the five days per week. The fifth day can be self-directed practice at home, outlined by the study investigator.

Where:
EARLY - The intervention will be conducted at a listed acute, subacute or outpatient site or the participant's home (if applicable).
LATE: The intervention will be conducted at a listed outpatient site or the participant's home (if applicable).
The preference is for all intervention to be conducted at a listed outpatient site. Home based therapy will be considered on a case-by-case basis. The factors contributing to this decision will include, number of other participants on the study, local procedures at listed sites regarding home visiting and location of the participant’s home.

When and how much:
EARLY - The intervention will be delivered within the first month after stroke. The purpose of the trial is to determine the maximum tolerated dose regimen, therefore “how much” therapy a participant will receive is dependent on which cohort they are recruited too. The duration of the intervention period (5 days) and the number of days of treatment per week (5 days) will be consistent across all cohorts. The number of sessions per day and the session intensity will be manipulated, with the starting dose for cohort 1 being 1x15min time on task session per day.
LATE - The intervention will start within the 3 to 9 month window post stroke. The purpose of the trial is to determine the maximum tolerated dose regimen, therefore “how much” therapy a participant will receive is dependent on which cohort they are recruited too. The duration of the intervention period (10 days) and the number of days of treatment per week (5 days) will be consistent across all cohorts. The number of sessions per day and the session intensity will be manipulated, with the starting dose for cohort 1 being 1x30min time on task session per day.

For both subgroups, the maximum dose will be a total of 360 minutes (6 hours) time on task. The number of sessions and session intensity delivered to cohort 2 and beyond will be based on a dose allocation algorithm. The study will escalate on number of sessions per day, followed by time on task.

Outcomes
Primary outcome [1] 322468 0
Maximum tolerated dose regimen of upper limb training post stroke will be identified using a set of pre-specified, dose limiting criteria that are regarded as sufficient to claim a tested dose is not tolerable. The participant will be asked about the reason for session cessation e.g., pain, fatigue, effort or other such as lack of interest. The reason will be recorded and if applicable an appropriate outcome measure will be taken e.g., visual analogue scale.
Timepoint [1] 322468 0
The maximum tolerated dose regimen will be determined at the conclusion of the trial, i.e., when the last recruited participant has completed the intervention.

Primary Outcome: Maximum tolerated dose regimen of upper limb training post stroke.
MTDR of upper limb training, will be identified from the dose allocation algorithm at the conclusion of the study, i.e., when the last participant, in the last cohort concludes the intervention period.

Secondary Outcomes:
1. To describe individual dimensions of the multidimensional MTDR in upper limb training post stroke. The individual dimensions will be identified from data extracted participants’ training logs and an exploration of the DLC. This will be summarised using means (standard deviations), median (interquartile range), counts, and proportions as appropriate.
2. To investigate potential efficacy outcomes to inform the design of a future phase II, upper limb stroke recovery trial. Potential efficacy outcomes will be reported as means (standard deviation) or median (interquartile range), for baseline and end of intervention timepoints.

Summary
Brief summary
DOSE-UP will bring us closer to understanding what the optimal dose of upper limb therapy is to maximise recovery. Our project will identify the maximum tolerated dose regimen (MTDR) of upper limb therapy at two different recovery points after stroke. The early in recovery subgroup will recruit participants 3 to 14 days post stroke and late in recovery subgroup will recruit participants 3 to 9 months post stroke. At time of consent, participants will be allocated a dose of therapy to test, and their response will determine the dose to be tested with future participants. We expect this study to provide answers to the question, what is the tolerable dose of upper limb training and support better development of intervention protocols for testing with stroke survivors in clinical trials.
