Table 1.

Stratified areas of distribution on the change amount of visual analogue scale (VAS) scores (unit: number of patients).

Range of change amount	SE	POE
Over +19	11	4
+10 to +19	4	1
0 to +9	6	12
−10 to −1	0	1
−20 to −11	0	1
Under −20	0	2

SE: self-efficacy; POE: perceptions of occupation enablement. The change amount was subtracted from the VAS score of 1-day preintervention from that of 1-day postintervention. The table shows the number of patients according to different change amount categories.
