Table 2.
Mean (SD) values of “actual flexion” during position sense tests shown as a percentage of the full range of cervical flexion. Values are based on the first attempt to achieve the target position during the initial set of tests on the first test day (n = 40). Intraclass correlation coefficient (ICC) and standard error of measurement (SEM) values are based on repeated within-day (n = 21) and between-day (n = 19) measurements.
| Target range of flexion |
||||
|---|---|---|---|---|
| 25% | 50% | 75% | ||
| Standing | Actual flexion (%) | 39 (10) | 60 (10) | 77 (11) |
| Within-day: ICC | 0.59 | 0.86 | 0.80 | |
| Within-day: SEM (%) | 8 | 6 | 6 | |
| Between-day: ICC | 0.78 | 0.82 | 0.85 | |
| Between-day: SEM (%) | 6 | 6 | 5 | |
| Sitting | Actual flexion (%) | 40 (9) | 60 (10) | 76 (10) |
| Within-day: ICC | 0.52 | 0.78 | 0.83 | |
| Within-day: SEM (%) | 7 | 7 | 6 | |
| Between-day: ICC | 0.80 | 0.86 | 0.87 | |
| Between-day: SEM (%) | 6 | 6 | 5 | |
