BACKGROUND Verbal augmented feedback ( VAF ) is commonly used in physiotherapy rehabilitation of individuals with lower extremity musculoskeletal dysfunction or to induce motor learning for injury prevention .
Its effectiveness for acquisition , retention and transfer of learning of new skills in this population is unknown .
OBJECTIVES First , to investigate the effect of VAF for rehabilitation and prevention of lower extremity musculoskeletal dysfunction .
Second , to determine its effect on motor learning and the stages of acquisition , retention and transfer in this population .
Effect of attention focus on acquisition and retention of postural control following ankle sprain.
OBJECTIVE To examine the effect of attentional focus instructions and dynamic balance training on ankle sprain recovery .  DESIGN R and omized controlled trial . SETTING Outpatient physical therapy department . PARTICIPANTS Forty volunteers ( age range , 19 - 33y ) referred to treatment within 4 months after sustaining a grade 1 or 2 ankle sprain with no concurrent impairments . Participants were r and omly allocated to 1 of 2 groups differing in training instructions . INTERVENTION Postural control training consisted of ten 20-second trials , performed on 3 consecutive days , at 2 stability levels of the Biodex Stability System ( BSS ) . Training instructions directed the participants to either an internal or an external focus of attention . Assessment s were conducted on the BSS pre- and post-training , and 48 hours after the last session ( retention test ) . MAIN OUTCOME MEASURES Overall stability as indicated by variance in platform displacement in all directions ; anteroposterior ( AP ) variance of platform displacement ; and mediolateral variance of platform displacement . RESULTS Increases in overall and AP stability were observed immediately following training in both groups and were maintained at the retention test . Interaction effect indicates greater improvement in the external-focus group . CONCLUSIONS Our results suggest that external focus of attention is advantageous for the learning of a postural control task following an ankle injury
