Study characteristics
Methods	Study design: RCT Method of randomisation: not stated
Participants	Number of participants: n = 21 Inclusion criteria: disorder of unilateral movement in lower limb, CVA less than 150 days previously, able to stand unsupported for longer than 30 seconds, able to walk farther than 7 m, able to understand visual/verbal commands, medically stable enough for 20 minutes of treatment, more than zero degrees passive ankle dorsiflexion and no hip, knee, ankle, foot pain
Interventions	(1) Motor learning Repetitive practice of context‐specific task Repetitive practice of stepping task The individual components delivered are listed in Table 6. Based on the individual components, this intervention is categorised as comprising functional task training Length of intervention period: two days Number of sessions and length of individual sessions: addition of 20 minutes, twice a day for two days. Participants had received routine physiotherapy, based on motor learning principles, although no routine physiotherapy was given on the two days of the intervention Intervention provider: not stated (2) Control (no treatment) The individual components delivered are listed in Table 6. Based on the individual components, this intervention is categorised as comprising no intervention Length of intervention period: no intervention Number of sessions and length of individual sessions: Participants had received routine physiotherapy, based on motor learning principles, although no routine physiotherapy was given on the two days of the intervention Intervention provider: no intervention This study is classified as intervention (functional task training) versus no treatment (Table 7)
Outcomes	Measures of postural control and balance: standing symmetry; step length symmetry; single stance symmetry
Notes	No outcomes included in analysis
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"were randomly assigned to either treatment or control group." No further details
Allocation concealment (selection bias)	Unclear risk	No information provided
Blinding of outcome assessment (detection bias) All outcomes	High risk	Participant not blinded Therapist not blinded Assessor not blinded
Incomplete outcome data (attrition bias) All outcomes	Low risk	No dropouts
Free of systematic differences in baseline characteristics of groups compared?	Unclear risk	No information
Did authors adjust for baseline differences in their analyses?	Unclear risk	No information
Other bias	High risk	The amount of treatment was very limited (four sessions over two days); this may have been insufficient to effect a change
