Abstract
Objective: Commenting on the return to sport after some injury is in doubt. The aim of this study was to investigate the relationship between test scores of movement control and a history of knee and ankle injury in active females. Methods: Statistical population of this study was 57 active females (22 healthy subjects, 19 subjects with a history of previous knee injury and 16 subjects with a history of previous ankle injury) with age ranging from 18 to 25 years old. In order to evaluate subjects, were used to the movement control test set consists of nine separate questions. Total maximum points in the subtests were 40 points, which less point was a better result in these tests. For statistical analysis, Kolmogorov-Smirnov test, Levene test, analysis of variance (ANOVA) and Tukey test were used (Significant at 95% and the alpha less than or equal 0.05, and using of the SPSS software v. 22). Results: The results of this study showed test scores of movement control earned by females with a history of ankle and knee injuries was significantly different with the healthy females (P=0.001).Compare scores of subjects with contact and non-contact injuries with healthy women showed that contact injury had higher scores than those who are non-contact injuries. The differences between the groups with any of these injuries are significant with no injury group (P=0.001).Cut-off point for this test was about 15.5. Conclusion: The scores of functional movement screening give a detailed model of the injury prevention to coaches in order to predict the risk of lower extremity injuries in athletes. So its need to coaches in order to the prevention of sports injuries, use the functional movement screening tests. To measure the performance level of the athletes before the start of the season, in order to identified athletes that are at risk of injury, in order to improve their capabilities.
Highlights
According to the results of analysis of variance (ANOVA) test, there was a significant difference in the scores of motion control test between the groups with a history of “ankle injury”, “knee injury”, and “no injury”
The results of Scheffe test revealed that there was a significant difference in the scores of motion control tests between the “ankle injury” and “no injury” groups and between the “knee injury” and “no injury” groups (P=0.001)
The score of these tests was lower for the “ankle injury” group than the “knee injury” group, no significant difference was observed between the two groups
Summary
The statistical population of this study included all active women aged 18-25 years in Kharazmi University. The participants’ performance was videotaped from four different angles by four digital cameras and used for scoring (required sequences were extracted by Corel protractor software) These tests lasted 25-30 minutes and included 9 tests: Double Knee Swing, Single leg 1⁄4 squat+hip turn, Bridge+straight leg lift & lower, Controlled shoulder internal rotation, 4 point-arm reach forward and back, Plank+lateral twist, One arm wall push, Split squat+fast feet, Lateral stair hop+rotational landing control [9, 13]. Each of these tests presents several criteria in the form of questions that require observational judgments about a person’s ability to control movement with standard criteria (40 criteria in total), each of which was answered in the affirmative or negative. The data were analyzed by SPSS software v. 22 (Table 1)
