Nearly two thirds of stroke survivors have deficits impairing ambulatory recovery. Conventional mobility outcome measures such as timed walks and functional independence measure (FIM) do not quantify free-living ambulatory behavior. This study compared step activity monitoring (SAM) with established instruments to assess ambulatory recovery across the outpatient subacute stroke rehabilitation phase.
We measured FIM mobility subscale, SAM-derived daily steps, Stroke Impact Scale (SIS) mobility scores, and timed walks in 11 subjects after discharge from inpatient rehabilitation and again 3 months later.
Significant improvement was measured in free-living step activity (mean gain 80%; P=0.001) but not with timed walks (P=0.4), FIM (P=0.08), or SIS mobility scales (P=0.3).
Microprocessor-linked SAM is a sensitive indicator of ambulatory recovery that measures improvements not captured by other conventional outcome instruments.
近三分之二的中风幸存者存在影响步行恢复的功能缺陷。传统的活动能力评估指标，如定时步行测试和功能独立性测量（FIM），无法量化日常生活中的步行行为。本研究比较了步数活动监测（SAM）与现有工具，以评估门诊亚急性中风康复阶段的步行恢复情况。
我们对11名患者在出院时及出院3个月后测量了FIM活动能力分量表、SAM得出的每日步数、中风影响量表（SIS）活动能力评分以及定时步行测试。
观察到日常生活中的步数活动有显著改善（平均增加80%；P = 0.001），但定时步行测试（P = 0.4）、FIM（P = 0.08）或SIS活动能力量表（P = 0.3）未显示出改善。
与微处理器相连的SAM是步行恢复的敏感指标，能够测量出其他传统评估工具未捕捉到的改善情况。
