2D Goniometer SmartLead User Manual
15.2.7 Back
1) Attach the proximal endblock to the sacral area at S1 as shown in figure 17.
2) With the patient upright and the goniometer near minimum length, attach the sliding endblock
to the back at T12-L1 (this will vary depending upon patient height).
3) Zero the goniometer with the patient in this upright position.
4) The SG150/B measures relative change in lumbar curvature through flexion/extension and
lateral flexion to both sides.
NOTE: The SG150/B is most effective for standing measurements with isolated X-X or Y-Y planar
movements. Crosstalk between the channels may be experienced with rotational movements.
Seated tasks and tight clothing may adversely affect the accuracy of the readings
15.2.8 Forearm Pronation/Supination
Attach the two endblocks of the torsiometer to the forearm as shown in figure 19 with the slider
mechanism approximately midway between the two extremes. Measurements of
pronation/supination may now be made from the grey plug. Movements of wrist flexion/extension or
radial ulnar deviation will not affect the output.
