Kilbreath 2006

Methods	Randomised cross‐over design Participants each performed 3 tasks in randomly presented order
Participants	13 participants Inclusion criteria: no significant musculotendinous or bony restrictions of upper limbs, no chronic disease independently causing significant disability or significant weakness of the upper limbs, sufficient strength in affected arm to move the arm forward at the shoulder and elbow and grasp with affected hand, score ≧ 1 on Frenchay upper limb test, comprehend simply instructions Note: it is unclear whether or not these were pre‐stated inclusion criteria, or whether these criteria are descriptors of the participants who were eventually included
Interventions	Each participant performed 2 bimanual and 1 unimanual task Each task involved participant reaching, grasping and transporting a tray with either affected arm (unimanual task), reaching for a large tray with both arms or 2 small trays (bimanual tasks) There was no training period ‐ movement and outcome measurement occurred simultaneously Each task was performed 5 times Profession of individual(s) providing training unclear (assume physiotherapist)
Outcomes	Secondary outcome: motor impairment ‐ kinematics of movement: the average of trials 3 to 5 for each condition; temporal outcomes: movement duration for hand to reach tray and for tray transport (hand to reach tray time selected (movement time)); spatial outcomes: lateral deviation of the hands, synchrony of hand movements and relative phase angle (lateral deviation of the hands selected)
Notes	Study included another 13 participants with no stroke history; not included in participant numbers or analysis Data are not available for the first phase only of this study and it is therefore not included in any analyses
Risk of bias
Bias	Authors' judgement	Support for judgement
Allocation concealment?	Unclear risk	All participants completed training in each condition
Blinding of outcome assessor?	Unclear risk	Assessments completed at the same time as the training
Intention to treat analysis?	Unclear risk	Not reported
Baseline similarity	Unclear risk	Participants not separated into different groups
