## 1 Introduction  
Poor quality movement control in the hip and pelvic region has been shown in biomechanical studies to affect joints lower in the kinetic chain, contributing to abnormal loading [1] and injuries at the knee, e.g., anterior cruciate ligament tears [2, 3]. The ability to assess hip and pelvic control in the clinical or field situation could help guide exercise strategies to improve muscular control appropriately. Movement screening tools have gained popularity, which includes movement tests mainly focused on predicting injury risk and/or guiding injury prevention programmes [4]. Current movement screening tools do not focus on hip and pelvic movement dysfunction or examine the influence of motor control exercises on hip and pelvic movement quality [5]. Therefore, the present study examined the relationship between two movement screening tools to investigate movement quality and their ability to assess hip and pelvic control. The functional movement screen (FMS) seems to be one of the most well-known movement screening tools. The FMS was designed to identify limb asymmetries, assess mobility and stability within the whole-body kinetic chain, and to detect poor-quality locomotor patterns during specific movement tasks [6; 7]. The FMS has been shown to be valid and reliable [8; 9] and is mainly used to assess athletes' risk of becoming injured, although systematic reviews have presented conflicting opinions about the ability of the FMS to predict injury [8; 10; 11]. It may be that the ability of the FMS to predict injury is limited to specific sports or types of injuries, but more homogeneous studies in terms of type of sport and/or injury are needed. Altered movement patterns and/or asymmetry, which can be detected during movement screening tests (e.g., FMS), may contribute to repetitive abnormal loading on joints, making them vulnerable to long-term damage. For example, increased hip medial rotation and adduction are associated with knee valgus [12], which has been linked to anterior cruciate ligament injury risk [2]. In addition, some authors [13; 14] have suggested that repetitive altered joint loading contributes to the development of osteoarthritis (OA). Thus, prevention strategies to improve and/or correct altered movement patterns could be considered in long-term management to potentially prevent the development of OA, since athletes are at an increased risk of subsequent OA [15]. This is particularly prevalent in football where higher rates of hip and groin injuries were among sports included in an epidemiological study [16]. The incidence of hip and groin pain in youth football was 14-22% [17; 18]. Youth athletes are also at increased risk of later OA due to altered joint loading and injury [15; 19]. Due to high injury rates and joint loading of the hip, knee, and ankle in youth football players, it would be useful to have movement screening tools that are sensitive to altered movement patterns or asymmetries of the hip and lower limbs. The FMS is not useful for assessing the functional status in hip dysfunction in athletes [20]. Similarly, [PERSON] et al. [21] found that the FMS rating was comparable in healthy football players and football players with mild hip or groin symptoms. These results suggest that the FMS does not discriminate between altered movement patterns in lower limb joints among footballers, so a more sensitive tool is needed. The recently developed Hip and Lower Limb Movement Screen (HLLMS) detects altered movement patterns and asymmetry, specifically of the hip, pelvis and lower limbs [5]. The HLLMS has been shown to have excellent intra-rater reliability and strong inter-rater reliability in adolescent male football players [5]. To date, two aspects of the HLLMS validity (criterion validity and sensitivity to change) have been indicated [22]. Additionally, preliminary observations show that tasks included in the HLLMS can detect movement control impairments in athletes [23; 24].
