Dickstein 1993

Methods	Randomised cross‐over design Participants each performed 3 movements in a randomly presented order This study was not designed or presented as a traditional RCT
Participants	25 participants Inclusion criteria: absence of cognitive impairments, unimpaired hearing, absence of movement disorders in unaffected upper extremity, ability to flex elbow on paretic side at least 30° from partial extension of 150°, not bilateral brain damage
Interventions	Each participant performed 1 familiarisation set of unilateral movements with the unaffected arm, then performed 3 sets of movements presented in a random order (unilateral (unaffected), unilateral (affected) or bilateral) Each set comprised 16 elbow flexion movements which were carried out in response to an auditory signal There was no training period ‐ movement and outcome measurement occurred simultaneously Profession of individual(s) providing training unclear (assume physiotherapist)
Outcomes	Secondary outcome: motor impairment ‐ temporal outcomes: reaction and movement time (movement time selected)
Notes	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 stated
Baseline similarity	Unclear risk	Participants not separated into different groups
