N2 - Objectives To examine the effects of joint mobilization and exercise training on neuromuscular performance in individuals with functional ankle instability (FAI). Design A cross-sectional study. Participants Forty five subjects with FAI were randomized into three groups: control (CG, n = 15, 27.9 ± 6.6yr), training (TG, n = 15, 26.9 ± 5.8yr) and mobilization with training group (MTG, n = 15, 26.5 ± 4.8yr). Intervention Four weeks of neuromuscular training for TG; neuromuscular training and joint mobilization for MTG. Main outcome measures Electromyography of the peroneus longus (PL), tibialis anterior (TA), and soleus (SOL) and the reaching distance of the Y balance test (YBT), dorsiflexion range of motion (DFROM), Cumberland ankle instability tool (CAIT), and global rating scale (GRS). Two-way repeated measures MANOVA were used with the significance level p <.05. Results MANOVA found significant group by time interactions on posterolateral reaching distance (p =.032), PL activation (p =.006–.03), DFROM (p <.001), CAIT (p <.001) and GRS (p <.001). The post hoc tests indicated significantly improved PL muscle activity and posterolateral reaching distance for MTG compared to TG (p =.004) and CG (p =.006). Conclusion Joint mobilization resulted in additional benefits on self-reported ankle instability severity, dorsiflexion mobility, and posterolateral balance performance in individuals with FAI, but its effects on general improvement, muscle activation, and other balance tasks remained uncertain.
