| Popis: | Objective To compare the long-term effects of external focus (EF) and internal focus (IF) of attention after 4 weeks of arm training. Design Randomized, repeated-measures, mixed analysis of variance. Setting Outpatient clinic. Participants Individuals with stroke and moderate-to-severe arm impairment living in the community (N=33; withdrawals: n=3). Interventions Four-week arm training protocol on a robotic device (12 sessions). Main Outcome Measures Joint independence, Fugl-Meyer Assessment, and Wolf Motor Function Test measured at baseline, discharge, and 4-week follow-up. Results There were no between-group effects for attentional focus. Participants in both groups improved significantly on all outcome measures from baseline to discharge and maintained those changes at 4-week follow-up regardless of group assignment (joint independence EF condition: F 1.6,45.4 =17.74; P 2 =.39; joint independence IF condition: F 2,56 =18.66; P 2 =.40; Fugl-Meyer Assessment: F 2,56 =27.83; P 2 =.50; Wolf Motor Function Test: F 2,56 =14.05; P 2 =.35). Conclusions There were no differences in retention of motor skills between EF and IF participants 4 weeks after arm training, suggesting that individuals with moderate-to-severe arm impairment may not experience the advantages of an EF found in healthy individuals. Attentional focus is most likely not an active ingredient for retention of trained motor skills for individuals with moderate-to-severe arm impairment, whereas dosage and intensity of practice appear to be pivotal. Future studies should investigate the long-term effects of attentional focus for individuals with mild arm impairment. |
