implemented in sports such as rugby, soccer, volleyball, handball, and basketball. 15 Commonly cited mechanisms of injury to the ankle joint include movements such as cutting to change direction and landing from a jump. 23 Many studies have investigated the clinical efficacy of wobble board-based intervention programs for ankle sprain prevention and treatment, showing improvements in neuromuscular function 3,8 and a reduction in injury occurrence. 22,33,35 Unfortunately, high levels of motivation and adherence are often lacking during therapeutic exercise programs, 31 possibly due to the repetitive nature of the exercises. Anecdotal evidence suggests that this may be particularly problematic in the case of preventative exercises, where there is no added rehabilitation incentive.Exergaming systems that incorporate exercises into on-screen computer games may offer a potential solution to improve adherence to clinician-prescribed exercise programs. Exergaming systems are computer games in which motion-tracking devices are used to capture body movements to complete on-screen games. These applications, when used for therapeutic exercise in a clinical setting, are referred to as therapeutic exergaming systems or P ostural control and coordination exercises are commonly prescribed by physical therapists for the prevention and rehabilitation of musculoskeletal disorders such as ankle sprains, and wobble boards are a training device commonly employed in clinical practice to challenge postural stability. 24 A recent systematic review of 227 studies reporting injury patterns in 70 sports t Study deSigN: Randomized controlled trial.t OBjeCtiveS: To compare the effects of wobble board exercises with and without feedback provided through integrating the wobble board movement into a computer game system, by comparing changes in postural stability and motivation.t BaCkgrOuNd: Therapeutic exergaming systems may offer a solution to poor adherence to postural control exercise regimes by improving motivation levels during exercise performance.t methOdS: Twenty-two healthy adults, randomly assigned to an exergaming group (n = 11) and a control group (n = 11), completed 12 exercise sessions. Dynamic postural stability was quantified at baseline and follow-up using the star excursion balance test and the dynamic postural stability index during a jump-landing task. Intrinsic motivation was measured at baseline using the Self-Motivation Inventory and at follow-up using the Intrinsic Motivation Inventory.t reSultS: Star excursion balance test scores showed a statistically significant (P.008) improvement in the posteromedial and posterolateral direction for both groups. No within-group change for the dynamic postural stability index or between-group difference for star excursion balance test or dynamic postural stability index scores were observed. The "interest and enjoyment" category of the Intrinsic Motivation Inventory showed significantly higher scores (P.001) in the exergaming group at follow-up, which was 1 of the 5 Intrinsi...
