Abstract

Background: There are varied reports in the literature regarding the association of the Functional Movement Screen™ (FMSTM) with injury. The FMSTM has been correlated with hamstring range of motion and plank hold times; however, limited research is available on the predictability of lower extremity range of motion (ROM) and core function on FMSTM performance.

Purpose/Hypotheses: The purpose of this study was to examine whether active lower extremity ROM measurements and core functional tests predict FMSTM performance. The authors hypothesized that lower extremity ROM and core functional tests would predict FMSTM composite score (CS) and performance on individual FMSTM fundamental movement patterns.

Study Design: Descriptive cohort study Methods: Forty recreationally active participants had active lower extremity ROM measured, performed two core functional tests, the single leg wall sit hold (SLWS) and the repetitive single leg squat (RSLS), and performed the FMSTM. Independent t tests were used to assess differences between right and left limb ROM measures and outcomes of core functional tests. Linear and ordinal logistic regressions were used to determine the best predictors of FMSTM CS and fundamental movement patterns, respectively.

Results: On the left side, reduced DF and SLWS significantly predicted lower FMSTM CS. On the right side only reduced DF significantly predicted lower FMSTM CS. Ordinal logistic regression models for the fundamental movement patterns demonstrated that reduced DF ROM was significantly associated with lower performance on deep squat. Reduced left knee extension was significantly associated with better performance in left straight leg raise; while reduced right hip flexion was significantly associated with reduced right straight leg raise. Lower SLWS was associated with reduced trunk stability performance.

Conclusions: FMSTM movement patterns were affected by lower extremity ROM and core function. Researchers should consider lower FMSTM performance as indicative of underlying issues in ROM and core function. Clinicians may consider ROM interventions and core training strategies to improve FMSTM CS.
