Using The FMSTM To Asses The Degenerative Changes Of Functional Performance In Mid-aged And Older People

Abstract

The Functional Movement Screen (FMS™) is increasingly popular for detecting impairments and limitations in basic functional movements. However, large-sample research is scanty to investigate the degenerative changes in terms of functional symmetry, agility, and stability associated with ageing. PURPOSE: To explore functional degeneration associated with ageing, by using the FMS™. METHODS: One hundred mid-aged (n=48, mean 54.75 years old, range 50-59) and older (n=52, mean 62.42 years old, range 60-69) community adults volunteered. There functional performance was assessed by using the FMS™. RESULTS: (1) The mean (±SD) total FMS score was 13.10 (±1.83) and 45% participants an asymmetry in at least one of the five FMS™ testing items that include bilateral assessments; (2) Pearson’s correlation showed that there was a significant and negative relationship between age and the total FMS™ scores (r=-0.278,P=0.005); (3) The Mann-Whitney U test showed that the scores for Hurdles and Rotary Stability were significantly worse in older participants, compared to their mid-aged counterparts (P=0.013 and P=0.048, respectively); (4) When a stepwise multiple regression was conducted on the FMS™ total scores, it was found that 85% of the variance in FMS™ scores could be accounted for by four variables: Push-up, Shoulder Mobility, Lunge, and Hurdle, with explained variance cumulating from 40, 56, 74 to 85% as the four variables were added into the equation. CONCLUSIONS: (1) The total FMS™ scores from this group of participants was lower than 14, suggesting increased risk of injury. Thus, specific intervention should be carried out to lower the risk; (2) When transferring from mid-aged to older stage, balance with single leg support and core stability may decrease significantly, indicating that these two factors should be taken seriously during intervention; (3) In order to improve total FMS™ score and decrease risk of injury in mid-aged and older individuals, exercises program should involve Push-up, Shoulder Mobility, Lunge, and Hurdle practice. The current study provided valuable information for better understanding of ageing process with regard to functional degeneration, and for developing specific exercise program that targets on these degenerative changes with ageing.
