    您好

    其實很多文獻資料都可以利用Google來進行搜尋,只是有些期刊資料是需要付費才能下載,不過很幸運的是您要的這一篇文獻不需要付費,網址如下:

    Association of Activity Limitations and Lower-Limb Explosive Extensor Power in Ambulatory People With Stroke

    Abstract

    Saunders DH, Greig CA, Young A, Mead GE. Association of activity limitations and lower-limb explosive extensor power in ambulatory people with stroke.

    Objective

    To determine whether the explosive lower-limb extensor power of the affected and unaffected sides, and any asymmetry, are associated with activity limitations after stroke.

    Design

    Cross-sectional observational study of baseline data from a randomized controlled trial.

    Setting

    Measurements made in a hospital clinical research facility.

    Participants

    Community-dwelling (N=66) subjects with stroke who were independently ambulatory. Subjects’ mean age was 7210 years.

    Interventions

    Not applicable.

    Main Outcome Measures

    The lower-limb extensor power of each lower limb (in W/kg), performance of specific functional activities (comfortable walking velocity, Functional Reach Test, chair-rise time, Timed Up & Go test), and global indices of activity limitation (FIM instrument, Rivermead Mobility Index, Nottingham Extended Activities of Daily Living).

    Results

    Low lower-limb extensor power in either lower limb was the principal factor from among the confounders we recorded that significantly (R2 range, .21–.46) predicted the limitation of specific functional activities, and low lower-limb extensor power in either lower limb was the principal predictive factor for global indices of activity limitation (R2 range, .13–.38). The degree of asymmetry of lower-limb extensor power between legs was low and had little or no predictive value.
