Abstract:
Objective:To observe any effect of dynamic instability training on the balance and posture control of persons with chronic ankle instability (CAI).Methods:Thirty persons with CAI were divided at random into a control group and an observation group, each of 15. Both groups received routine rehabilitation interventions (including ankle strength training, kinesio taping, and vibration training), while the observation group additionally underwent 20 minutes of dynamic instability training daily, 5 days a week for 4 consecutive weeks. Before and after the treatment, everyone′s balance was evaluated using the Berg balance scale (BBS) and the star moving balance test (SEBT). Surface electromyography (sEMG) was used to collect electromyograms of the affected peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles of both groups within 100ms before and after landing in the jump-landing test. The intensity of muscle activation was thus analyzed.Results:After the treatment there was significant improvement in the average BBS scores, anterior medial SEBT, medial SEBT and posterior medial SEBT results of both groups. On average, all three SEBT results [(80.27±4.06)cm, (90.27±4.06)cm and (97.73±3.47)cm respectively] were significantly better in the observation group than in the control group. The standardized integrated electromyographs of the peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles on the affected sides showed significant improvement compared with before the treatment, but there too the observation group′s results were significantly better than those of the control group.Conclusions:Combining dynamic instability training with conventional rehabilitation can further improve the balance and postural control of persons with chronic ankle instability.
