Abstract

Purpose. This study investigated and correlated between the dynamic limit of stability and functional level of the ankle joint in patients with unilateral chronic ankle instability after receiving neuromuscular training.

Material and Methods. Forty patients of both sexes were examined. They were assigned into two equal groups; experimental (Group A) and control (Group B). The Biodex Balance system was used for assessing the dynamic limit of stability and the ankle joint functional assessment tool (AJFAT) was used for assessing the functional level of the ankle joint before and after a 4-week period during which Group A received neuromuscular training.

Results. Mixed Design MANOVArevealed that the dynamic limit of stability test duration decreased and the AJFAT score increased significantly in Group A after training compared with before (p < 0.05). Similarly, the dynamic limit of stability test duration decreased and the AJFAT score increased significantly in Group A compared with Group B after training (p < 0.05). Pearson correlation showed significant strong negative correlation between the dynamic limit of stability test duration and AJFAT score in Group A (p < 0.05).

Conclusion. Improvement in dynamic stability and functional joint stability level was perceived with neuromuscular training. This improvement reflects the ability of training to enhance ankle joint sensorimotor capabilities.
