1. The subject may be seated or standing (whichever is more comfortable)in a forward flexed position with the thoracic spine in as horizontal aposition as can be achieved. Locate and place a skin mark over the T1and T12 spinous processes. Place the first inclinometer, aligned in theaxial and vertical planes, over the TI spinous process while holding thesecond over the T12 spino us process. The trunk should be in the neutralrotational position while the inclinometers are "zeroed out" (Figure 91a).2. Ask the subject to rotate the trunk maximally to the right and recordboth angles. Subtract the T12 inclination from the T1 inclination for thethoracic tight rotation angle (Figure 91b). Return the trunk to the neutralposition so that both inclinometers read "0" again.3. Instruct the subject to rotate the trunk maximally to the left as far aspossible, again recording both inclinometer angles and subtracting the T12angle from the T1 inclinometer angle to obtain the thoracic left rotationangle (Figure 91c).4. Repeat the procedure three times. Only the left and tight rotationangles need be consistently measured to within +/-10% or 5°, whicheveris greater. The final measurement for impairment evaluation is thegreatest' angle measured.5. Consult the Abnormal Motion Section of Table 55 to determine theimpairment of the whole person.Measurement of thoracic spine rotation using single inclinometermethod(for automated devices capable of calculating compound joint motions)
