PostureRay® Comparison Evaluation of Pre-Treatment and Re-Exam 1 LL X-rays.
| Measurement | Normal Values | Xray 1 Values | Xray 2 Values |
|---|---|---|---|
| RRA L1-L2 | −5° | −7.5° | −5.4° |
| RRA L2-L3 | −6° | −12.1° | −13.7° |
| RRA L3-L4 | −9° | −16.0° | −18.5° |
| RRA L4-L5 | −19° | −11.8° | −11.6° |
| RRA L5-S1 | −33° | −14.8° | −15.6° |
| ARA L1-L5 | −40° | −47.3° | −49.1° |
| SBA | 40° | 29.4° | 33.5° |
| Tz L1-L2 | 0 mm | −1.1 mm | −0.5 mm |
| Tz L2-L3 | 0 mm | −1.0 mm | −0.8 mm |
| Tz L3-L4 | 0 mm | −0.5 mm | −0.8 mm |
| Tz L4-L5 | 0 mm | 13.3 mm | 7.1 mm |

Table 1 shows relative rotational angles (RRA) of measurement from L1 to S1, the sacral base angles (SBA), the translations in the z-axis (Tz) per segment from L1 to S1, and the Tz of L1 to S1 comparisons of pre-treatment and re-exam 1 lateral lumbar (LL) x-rays. SBA improved from 29.4° to 33.5° (normal is 40.0°), Tz L4-L5 improved from 13.3 mm to 7.1 mm (normal is 0.0 mm), and Tz L1-S1 improved from 29.3 to 25.1 (normal is 0.0 mm). RRA = Relative Rotational Angle of Measurement.
ARA = Absolute Rotational Angle of Measurement
SBA = Sacral Base Angle
Tz = Translation in the z-axis
Tz in Red Exceed Established Normal
Xray 1 Values = Pre-treatment views
Xray 2 Values = Re-Exam 1 following 30 sessions over 11 weeks
