Table 2. Classification Distribution for the Full Sample, Factors Influencing Classifications, and Classification Distributions of the 3 Subgroupsa.
| Full sample (n = 156) | Improved Performance, P+ | Unimproved Performance, P− | |
| Improved capacity, C+ | 20% (31) | 59% (92) | |
| Unimproved capacity, C− | <1% (1) | 21% (32) | |
| Factors significantly influencing classifications in the full sample (n = 155)b | C+P+ | C+P− | C−P− |
| Age, y | 60 (28, 87) | 65 (29, 86) | 70 (45, 88) |
| Time since stroke or diagnosis, mo | 1.6 (<1, 76) | 4.1 (<1, 212) | 38 (1.4, 263) |
| Number of assessments | 2 (2, 7) | 2.5 (2, 7) | 4 (2, 7) |
| Stroke upper limb (n = 51) | Improved Performance, P+ | Unimproved Performance, P− | |
| Improved capacity, C+ | 51% (26) | 33% (17) | |
| Unimproved capacity, C− | 0% (0) | 16% (8) | |
| Stroke walking (n = 48) | |||
| Improved capacity, C+ | 0% (0) | 100% (48) | |
| Unimproved capacity, C− | 0% (0) | 0% (0) | |
| PD walking (n = 57) | |||
| Improved capacity, C+ | 9% (5) | 47% (27) | |
| Unimproved capacity, C− | 2% (1) | 42% (24) | |
aValues are % (n), or medians (min, max). Values are rounded to the nearest whole percentage; totals may not equal 100% are due to rounding.
bAnalyses exclude the C−P+ group since it had only 1 participant. Significant differences between the 3 groups as indicated by P = 0.007 for age and P < 0.0001 for time and number of assessments.
