Using the method of quality assurance of stroke rehabilitation developed at the University of Minnesota (UMn) by assessing patient outcomes on the basis of a modification of the Williamson Functional Limitation Scale (WFLS), 84 patients (group H) with completed stroke were surveyed 8 months to 13 years following treatment without rehabilitation at Hennepin County General Hospital. Because a greater percentage (42%) than estimated (29%) had died, the percentage of those not independent in self-care (31%) was less than estimated (46%). These patients were not matched with a group given rehabilitation (group U) previously studied at UMn but were generally less severely involved, although older on the average. However, even so, only 47% of those still living were independent in self-care in group H in contrast to 69% in group U. Also 42% of group H were in nursing homes or board-and-care facilities while only 18% of the rehabilitated group were. Although the modified WFLS is used in outcome studies for quality of rehabilitation, it is even sensitive enough to show differences in outcomes in a comparative study such as this.
采用明尼苏达大学（UMn）开发的中风康复质量保证方法，以对威廉姆森功能受限量表（WFLS）进行修改为基础评估患者预后，对亨内平县综合医院84例接受过无康复治疗的中风患者（H组）在治疗后8个月至13年进行了调查。由于死亡患者比例（42%）高于预期（29%），自理不独立患者的比例（31%）低于预期（46%）。这些患者未与UMn之前研究过的接受康复治疗的一组患者（U组）进行匹配，但总体病情较轻，不过平均年龄更大。然而，即便如此，H组中仍在世的患者只有47%能够自理，而U组这一比例为69%。此外，H组中有42%的患者住在养老院或寄宿护理机构，而接受康复治疗组这一比例仅为18%。尽管修改后的WFLS用于康复质量的预后研究，但它在这样的比较研究中也足够灵敏，能够显示出预后的差异。
