Relationships between the Functional Movement Screen Score and Y-Balance Test Reach Distances

Abstract

Background: The Functional Movement Screen (FMS) is used to evaluate key movement patterns, functional symmetry, and identify individuals that are at elevated risk of injury. The purpose of this study was to assess whether dynamic postural control is a significant component of the composite FMS score by comparing it with Y-Balance Test (YBT) reach distances. Methods: Seventy-eight participants (including 40 males) performed the standardized FMS protocol followed by the YBT. The YBT reach distances were normalized to leg length and averaged between sides and trials. The individual reach directions were evaluated, and were also summed to form an aggregate YBT distance (TotalY). Results: We observed weak correlations between the composite FMS score and normalized posterolateral reach, normalized posteromedial reach, and the TotalY (r=0.36, 0.37, and 0.36, respectively; all p< 0.05). There was no correlation between the composite FMS score and normalized anterior reach (r=0.22; p=0.053). Together these findings demonstrate partial correspondence between the two tests. Conclusion: This indicates that dynamic postural control is a small component of the aggregate FMS score.

The Relationship Between Functional Movement Screening and Joint Range of Motion, Y-Balance Test and Countermovement Jump in Amateur Soccer Players

“…In other studies conducted on university-trained athletes, a positive correlation was found between the FMS total scores and total LQYBT scores (18,31). In another study conducted on sedentary female and male individuals, a weak positive correlation was found between FMS and LQYBT total scores (15). Silva et al (28) stated that they found a positive relationship between FMS total score and CMJ in a similar study on soccer players.…”

Correlations between the Functional Movement Screen (FMS), dynamic balance, and vertical jumping ability in men and women

“…It is required for locomotion skills such as walking and running, and therefore dynamic balance is a key element in preventing sports injuries [9]. However, many studies of the relationship of the FMS and dynamic balance have been carried out using mainly the Y-Balance test and the Star Excursion [10][11][12][13][14][15]. In most studies, the tests used were based on the subject's immobile position, in which the subject reaches out with a limb or tilts the whole body in a certain direction [16].…”

Dynamics of Body Composition and Body Image of Sedentary Working Women Who Attend Zumba or Functional Training Programs: Pilot Study

“…Functional training is designed to enhance dayto-day activities, recreational activities and/or sports activities. The object of this training is the neuromuscular system, where movements are trained (muscle groups and nervous system), not only muscles (Beckham & Harper, 2010). Functional workouts are effective in improving muscle strength, balance, mobility, and the quality of daily movements.…”
