Using the Functional Movement Screen™ to evaluate the effectiveness of training.
ABSTRACT The Functional Movement Screen™ (FMS) has demonstrated some efficacy in the prediction of injuries and is thus used by many practitioners to make recommendations for exercise. However, questions remain regarding its utility as a means to evaluate the effectiveness of training. Sixty firefighters volunteered to participate, and their FMS scores were examined before and after 12 weeks of training. Individuals were graded on how they chose to perform rather than how they could perform. The participants were assigned to 1 of 3 groups: intervention 1, intervention 2, or control. The 2 intervention groups received three 1.5-hour training sessions each week and differed in the emphasis that was placed on movement quality. Sagittal and frontal plane videos were used to grade the FMS with 3 methods: the standard 0-3 scale, a 100-point scale that weighted specific compensations (research standard), and a modified 100-point scale whereby grades were assigned based on the total number of compensations present. There were no significant differences in the total FMS scores for any group posttraining. However, the scores of 85% of the firefighters who did not receive training did change. The 100-point scale methods resulted in more FMS score changes posttraining, but the between-group interactions were identical to those found with the standard scoring method. The control group's scores were not consistent pretraining and posttraining; thus, the influence of each intervention could not be evaluated. Currently, the FMS might provide a momentary impression of general movement quality, although further efforts would likely assist in the development of better ways to implement the test, interpret the results, and generate reliable scores.

ABSTRACT: Abstract The functional movement screen is developed to examine individuals' movement patterns through 7 functional tasks. The purpose of this study was to identify the internal consistency and factor structure of the 7 tasks of the functional movement screen in elite athletes; 290 elite athletes from a variety of Chinese national teams were assessed using the functional movement screen. Cronbach's alpha was calculated for the scores of the 7 tasks. Exploratory factor analysis was performed to explore the factor structure of the functional movement screen. The mean and standard deviation of the sum score were 15.2 ± 3.0. A low Cronbach's alpha (0.58) was found for the scores of the 7 tasks. Exploratory factor analysis extracted 2 factors with eigenvalues greater than 1, and these 2 factors explained 47.3% of the total variance. The first factor had a high loading on the rotatory stability (loading = 0.99) and low loadings on the other 6 tasks (loading range: 0.04-0.34). The second factor had high loadings on the deep squat, hurdle step and inline lunge (loading range: 0.46-0.61) and low loadings on the other 3 tasks (loading range: 0.12-0.32). The 7 tasks of the functional movement screen had low internal consistency and were not indicators of a single factor. Evidence for unidimensionality was not found for the functional movement screen in elite athletes. More attention should be paid to the score of each task rather than the sum score when we interpret the functional movement screen scores.Journal of Sports Sciences 01/2015; 33(11):1166-1172.

ABSTRACT: Study Background: The trunk stability push-up (TSPU) is a closed-chain test that can measure upper-body functional strength, but may not relate to sport-specific performance. The bilateral medicine ball chest pass (MBCP) is a more sport-specific open-chain assessment. This research investigated whether the TSPU related to bilateral MBCP to determine whether it was a valid test of team sport upper-body function. Methods: 32 male team sport athletes were assessed in the TSPU, and completed bilateral and unilateral MBCP with a 1-kilogram ball. Between-arm asymmetries were calculated for the unilateral MBCP. Participants were split into groups (high, intermediate, low) according to TSPU scores, and bilateral MBCP performance (smallest worthwhile change above or below group mean). This determined whether either test gave a clearer indication of upper-body function. Between-group differences were determined by a one-way analysis of variance (p < 0.05), with Bonferroni post hoc. Data was pooled for a Spearman’s correlation analysis (p < 0.05). Results: For the TSPU, 10 participants scored 3; 20 scored 2; 2 scored 1. When TSPU performance split the groups, the low performers had poorer bilateral and left-arm MBCP when compared to the high performers (p = 0.005-0.016). When bilateral MBCP performance divided the sample, high performers (n = 12) were superior in bilateral and unilateral MBCP, and the TSPU (p ≤ 0.001-0.023), when compared to low performers (n = 14). The high performers also had a better bilateral MBCP when compared to intermediate (n = 6) performers (p = 0.003). Between-arm asymmetries did not differentiate performance ability. Large-to-very large correlations were found between bilateral and unilateral MBCP. Conclusion: The bilateral MBCP is a more effective test of upper-body function than the TSPU, and can discriminate between athletes with different upper-body function. This assessment related to the unilateral MBCP and TSPU, indicating its applicability for team sports.

ABSTRACT: : The purpose of this study was to analyze the transference of increased passive hip ROM and core endurance to functional movement. 24 healthy young men with limited hip mobility were randomly assigned to 4 intervention groups: 1)Stretching; 2)Stretching plus hip/spine disassociation exercises; 3)Core endurance; 4)Control. Previous work has documented the large increase in passive ROM and core endurance that was attained over the 6 week interventions, but whether these changes transferred to functional activities was unclear.Four dynamic activities were analyzed before and after the 6 week interventions: active standing hip extension, lunge, a standing twist/reach maneuver, and exercising on an elliptical trainer. A Vicon motion capture system collected body segment kinematics, with hip and lumbar spine angles subsequently calculated in Visual 3D. Repeated measures ANOVAs determined group effects on various hip and spine angles, with paired t-tests on specific pre/post pairs.Despite the large increases in passive hip ROM, there was no evidence of increased hip ROM utilized during functional movement testing. Similarly, the only significant change in lumbar motion was a reduction in lumbar rotation during the active hip extension manoeuvre (p< 0.05).These results indicate that changes in passive ROM or core endurance do not automatically transfer to changes in functional movement patterns. This implies that training and rehabilitation programs may benefit from an additional focus on 'grooving' new motor patterns if new found movement range is to be utilized.The Journal of Strength and Conditioning Research 04/2013; 27(10).
