Abstract
Objective: To evaluate the effect of surface type on muscle activity of ankle stabilizing muscles in subjects with chronic ankle instability. Design: Case controlled, repeated measures study design. Subjects: 28 subjects with chronic ankle instability and 28 healthy controls. Methods: Subjects performed a barefooted single legged stance on uni-axial and multidirectional unstable surfaces. Muscle activity of the mm. peroneus longus/brevis, tibialis anterior, gastrocnemius medialis was registered using surface electromyography. Mixed model analysis was used to explore differences in muscle activity between subjects with chronic ankle instability and controls, and the effect of surface type on muscle activity levels within subjects with chronic ankle instability. Results: No differences were found between subjects with chronic ankle instability and healthy controls. Within subjects with chronic ankle instability, balancing along a frontal axis and on the BOSU evoked overall highest muscle activity level and the firm surface the least. Balancing on the firm surface showed the lowest tibialis anterior/peroneus longus ratio, followed by balancing along a frontal axis and on the Airex pad. Conclusions: Clinicians can use these findings to improve the focus of their balance training program by gradually progressing in difficulty level based on muscle activation levels taking cocontraction ratio’s into account.
