AmputationAmputations distal to the proximal interphalangeal joint and proximal tothe distal interphalangeal joint are expressed as a percentage between 45%and 80%.Example: If 50% of the middle phalanx is amputated, the impairment is45% + (50% x 35%) = 63%.Metatarsophalangeal Joint of the Second through Fifth Toes-DorsiandPlantar-flexionAbnormal MotionPlace patient in the neutral position (Figure 50).Dorsi-flexion: Center the goniometer beneath the metatarsophalangeal jointof the toe being tested (Figure 61a). Record the goniometer reading.With the patient dorsi-flexing the toe as far as possible (Figure 61b),follow the range of motion with the goniometer arm. Record the angle thatsubtends the arc of motion.Plantar-flexion: Center the goniometer over the metatarsophalangeal joint
