Comparison of visual and objective quantification of elbow and shoulder movement in children with obstetric brachial plexus palsy

Table 2 Normative values and cut off points for conversion of angular into Active Movement Scores

		Active Movement Score cut-offs
Direction of movement	*Norm – Maximal range (95% CI)**	Motion ≤ 1/2 range	Motion > 1/2 range	Full motion
Elbow flexion	145.4° (144.0°–146.8°)	≤ 71.1°	71.2–143.9°	≥ 144.0°
Elbow extension	0.6° (0.1°–1.7°)	≥ 71.2°	1.8°–71.1°	≤ 1.7°
Shoulder abduction	185.4° (184.4°–186.4°)	≤ 92.1°	92.2°–184.3°	≥184.4°
Shoulder flexion	168.4° (167.4°–169.4°)	≤ 83.6°	83.7–167.3°	≥ 167.4°
