Functional movement screen and Y balance tests in adolescent footballers with hip/groin symptoms

Abstract

Objectives: To assess the correlation between the functional movement screen (FMS) and Y balance test (Y-BT) performance, and the self-reported hip/groin problems, and to compare healthy with hip/groin pain participants. Design: a cross-sectional study. Setting: Sports hall in a football club. Participants: 43 elite adolescent football (soccer) players Main Outcome: The Copenhagen Hip and Groin Outcome Score (HAGOS), Anterior, posterolateral and posteromedial distance of Y-BT, FMS score. Measures: Y balance and FMS test kit, HAGOS questionnaire. Results: The posterolateral, posteromedial distance and composite reach score of the Y-BT were lower in participants with hip/groin problems (p<0.05). FMS performance was similar in healthy and hip/groin groups. There was a weak correlation (r=0.32, p=0.03) between the HAGOS Activities of Daily Living subscale and FMSstabil. In the Y-BT the posterolateral reach was weakly correlated with Symptoms (r=0.35-0.44, p<0.02) and moderately correlated with Pain (r=0.44, p<0.01) subscales. Posteromedial direction reach with the right leg was weakly correlated with Symptoms (r=0.32, p=0.04) and Pain (r=0.39, p=0.01). The Y-BT composite score was moderately correlated with Symptoms and Pain (r=0.42-0.44, p<0.01). Conclusions: The Y-BT and the FMS subtests were weakly or moderately correlated with selfreported hip/groin problems. Thus, these tests should be investigated further in adolescent footballers because they may have potential to predict hip and groin problems.

Systematic Review and Meta-Analysis of the Y-Balance Test Lower Quarter: Reliability, Discriminant Validity, and Predictive Validity

Normative performance values of modified Star Excursion Balance Test and Limb Symmetry in female adolescent footballers

“…Within female adolescent football, normal performance values during the mSEBT and subsequent LSI scores have not been well established 28 . Asymmetrical performance has been identified as a characteristic of adolescent footballers during completion the mSEBT 29 , with a trend for decreasing asymmetry with increasing age.…”

“…A comparative reference data set for normal mSEBT and derived LSI scores are therefore required for identification of thresholds for participation and injury risk in female adolescent footballers 28 . Prior to this, it is important to 1) establish the extent of the variability within the mSEBT testing process and identify if differences exist between the dominant and non-dominant legs, as each influence the derived LSI scores 2) report normative performance value ranges for dominant, non-dominant leg and LSI scores across the mSEBT components and 3) investigate if there is a relationship between age and either the mSEBT or LSI scores.…”
