Abstract
Introduction: Lateral ankle sprain is the most common ligament lesion in athletes, which consequences the functional ankle instability. According the incidence rate of ankle sprain there is more need for rehabilitation of this injury and functional ankle instability. Hoppings are dynamic exercises techniques for lower extremities as functional training and has a multiplicity of muscular strength, neuromuscular coordination, joint stability, balance and joint proprioception, and used in the final stages of rehabilitation as an evaluation criterion for the return to the activity. Therefore, the purpose of this study was to investigate the effect of these exercises on walking performance and pain index in subjects with ankle functional instability.
Methodology: 28 athletes with functional ankle instability participated in this randomized controlled trial. The samples were randomly divided into control and exercise groups (exercise group with age 22.78±2.76 years, height 187.96±7.93 cm, weight 82.59±9.51 kg and controlled group with age 22.57±2.76 years old, height 185.69±7.28 cm, weight 78.35±7.02 kg).
The instrument for collecting information of this study were Cumberland questionnaire for assessing the severity of ankle instability, a visual analog scale (VAS) for assessing pain intensity, and TUGT test for assessing walking performance. Hopping training protocol was performed for 6 weeks, 3 sessions per week on the training group. for analyzing data, descriptive statistic, independent t-test and paired t-test were used at a significant (P<0.05) level.
Results: Paired t-test showed a significant improvement in walking performance and pain score in the training group after 6 weeks of hopping exercises (p<0.05). Also, between-group comparisons of independed t-test showed a significant improvement in pain score and walking performance of experimental group compared to control group after 6 weeks of hopping exercises (p<0.05).
Discussion: According to the findings of the research, it can be concluded that these exercises increase the proprioception by activating damaged mechanoreceptors in the ankle region, reconstructing the pathways associated with these receptors and other muscle receptors therefore it improves gate variables in these individuals and increases their walking performance. Also increase in sensory information inputs reduces the input of pain information in the cortex and thereby reduces the pain score in these individuals. Therefore, hopping exercises improve the quality of life of these individuals
