Abstract

BACKGROUND:

Ankle sprains are the most common sports-related injury, associated with a high rate of recurrence and societal costs. Recent studies have emphasized the effectiveness of both neuromuscular training and bracing for the secondary prevention of ankle sprains.

PURPOSE:

To evaluate the cost-effectiveness of the separate and combined use of bracing and neuromuscular training for the prevention of the recurrence of ankle sprains.

STUDY DESIGN:

Economic and decision analysis; Level of evidence, 2.

METHODS:

A total of 340 athletes (157 male and 183 female; aged 12-70 years) who had sustained a lateral ankle sprain up to 2 months before inclusion were randomized to a neuromuscular training group (n = 107), brace group (n = 113), and combined intervention group (n = 120). Randomization was stratified by medical treatment of the inclusion sprain. Participants in the neuromuscular training group underwent an 8-week home-based exercise program. Participants in the brace group received a semirigid ankle brace to be worn during all sports activities for a period of 12 months. Participants allocated to the combined group underwent both interventions, with the ankle brace to be worn during all sports activities for a period of 8 weeks. The recurrence of ankle sprains and associated costs were registered during the 1-year follow-up.

RESULTS:

There were no differences between groups at baseline with regard to age, sex, sports participation, previous injury, or knowledge of preventive measures. The incremental cost-effectiveness ratio (ICER) of the brace group in comparison with the combined group was -€2828.30 (approximately--US$3865.00), based on a difference in the mean cost of -€76.16 (approximately--US$104.00) and a difference in the mean effects of 2.68%. The ICER of the neuromuscular training group in comparison with the combined group was €310.08 (approximately US$424.00), based on a difference in the mean cost of -€28.37 (approximately--US$39.00) and a difference in the mean effects of 9.15%.

CONCLUSION:

Bracing was found to be the dominant secondary preventive intervention over both neuromuscular training and the combination of both measures.
