Table 1 Proportion of valid measures for each movement

Movement, N=77	MP-BV, mean ± SD	Inclinometer, mean ± SD	Difference in absolute value between the MP-BV and the inclinometer, mean ± SD	Proportion of valid measures (95% CI)
Flexion	147.1±27.7	155.3±11.4	14.8±25.2	59.74% (0.4879; 0.7069)
Pronation	94.6±15.5	91.8±12.2	8.1±6.9	68.83% (0.5849; 0.7918)
Supination	72.3±14.4	78.8±11.6	10.9±8.9	62.34% (0.5152; 0.7316)

Note: Data is measured in degrees.
