Association between rolling and motor function in community-dwelling healthy female adults

Abstract

【Introduction】During the development of locomotion, rolling is the earliest pattern used for floor mobility, and it remains a useful mobility skill throughout an individual's lifetime. And,rolling is a basic indispensable movement for independently performing activities of daily living. Although the rolling elements are closely related to the basic movements that follow,no studies have examined the relationship between rolling and motor function or basic movements. The purpose of this study was to clarify the association between rolling and motor function.【Methods】We included 42 community‐dwelling healthy female adults, with a mean age of 55.4±18.6 years. The following tests were performed to examine the relation‐ship between the time‐to‐rolling and each motor function: rolling time, 30‐second chair stand test (CS‐30), Timed ”Up&Go”test(TUG), Figure‐of‐8 Walk Test at maximum speed (F8Wmax), maximal walking speed, and grip strength, quadriceps mus‐cleandtoegripstrength.【Results】Significant correlations were found between the time‐to‐rolling and motor functions (CS‐30, TUG, F8Wmax, maximal walking speed). The correlation coefficient between rolling to the right and to the left was 0.84, significant at p＜0.01.【Conclusions】The study results showed an association between rolling and motor function in community‐dwelling healthy female adults, suggesting those who can roll faster may have better walking and balance abili‐ties than those who roll slower. In addition, it was suggested that practicing rolling improves motor function and basic movements in persons who need help and supervision in activities of daily living, and may increase their level of independ‐ent locomotion.
