2.5. Knee Flexion and Extension ROM Measurement
knee flexion and extension ROM
BLIND
The physical therapist measured knee flexion and extension ROM using a goniometer [The participant was laid in a supine position, and passive knee flexion and extension ROM that could be tolerated was measured. Measurements were performed on the bed. In this study, we were not able to blind the investigators to the intervention information. We have calculated the intraclass correlation coefficient (ICC) for knee flexion and extension ROM, and we confirmed the high reliabilities for knee extension and flexion ROM (ICC = 1.00 and 0.92, respectively).
