Round the figures to the nearest 10°.From Figure 25 (p. 29), match the measured flexion and extensiondegrees (V) to their corresponding impairments of flexion (I F %) andextension (I E %).Add the values of flexion and extension impairment to obtain fingerproximal interphalangeal joint motion impairment.If the proximal interphalangeal joint is ankylosed, measure the positionand match it to the corresponding ankylosis (I A %) impairment in Figure 25(p. 29). Ankylosis in the functional position (40° flexion) is given thelowest impairment value (50%).Example: Middle finger proximal interphalangeal joint measures -20°extension and 60° flexion:I E % = 7% I F % = 24%7% + 24% = 31% impairment of the middle finger proximalinterphalangeal joint motion.Example: Proximal interphalangeal joint ankylosis in 40° flexion: I A % =50% impairment of the proximal interphalangeal joint motion.Metacarpophalangeal joint-Flexion and ExtensionMeasure the maximum flexion and extension and record the goniometerreadings (Figures 26 & 27, p.30). Round the figures to the nearest 10°.From Figure 28 (p. 30), match the measured flexion and extensiondegrees (V) to their corresponding impairments of flexion (I F %) andextension (I E %).Add the values of flexion and extension impairment to obtain fingermetacarpophalangeal joint motion impairment.
