Abstract

OBJECTIVE:

To examine the effect of attentional focus instructions and dynamic balance training on ankle sprain recovery.

DESIGN:

Randomized 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 randomly 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. Assessments 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.
