A Mechanical Sensor Designed for Dynamic Joint Angle Measurement

Figure 7

Bland-Altman plot of the joint motion measured by MGR and MAS: (a) hip flexion, (b) hip extension, (c) hip FROM, (d) knee flexion, (e) knee extension, (f) knee FROM, (g) ankle plantar flexion, (h) ankle dorsiflexion, and (i) ankle FROM. Almost all data points were within range of ±2 standard deviation lines, and hence measurements made by MGR and MAS were agreeable and repeatable. Remarks: dots represent the “difference”; solid lines represent the “mean difference”; dotted lines represent the “mean standard deviation lines.”
