Abstract
Electromyographic impairment is one of the most important issues following functional ankle instability. The purpose of this study was to compare the effects of neuromuscular and TRX exercises on the onset of electromyographic activity of lower-limb selected muscles in athletes with functional ankle instability.
A total of 35 college athletes with functional ankle instability voluntarily participated in this study. Subjects were randomly divided into three groups: neuromuscular, TRX exercises, and control group. The electromyographic onset of the 6 selected muscles was measured by surface electromyography and recorded in pre-test and post-test. Each exercise group performed their exercises in 18 sessions during 6 weeks. The control group performed no specific exercise activities. ANOVA repeated measure with Bonferroni's post-hoc test was used for statistical analysis.
Results showed that the improvement in onset of electromyographic activity was significant in all selected muscles in TRX group between pre-test and post-test(p=0.001). In the neuromascular group, the improvement occured in lower-limb distal muscles (Tibialis anterior-Lateral gastrocnemius-Proneus longus) between pre-test and post-test(p=0.001) not in proximal muscles(Rectus femoris-Gluteus maximus-Gluteus medius)(p≥0.05). There was no significant difference between pre and post-test in control group(p≥0.05).
improved electromyographic onset after the exercise can be attributed to changes in the nervous system motor control programs. TRX exercises provide proximal to distal motor control during lower-limb functional activities due to their impact on the muscles of the central body. Therefore, TRX exercises can be introduced as an alternative to neuromuscular exercises for rehabilitation of functional ankle instability using a balance board.
