The purpose of this study is to investigate the X-ray evaluation method with physical examination for the hemiplegic shoulder subluxation with seven radiologic parameters: Vertical Distance 1(Supine) [VDI(S)], Vertical Distance 1(Erect)[VDI(E)],
Vertical Distance 2(VD2), V-Shape Angle 1(VS1), V-Shape Angle 2(VS2), Scapular Rotation Angle(SR), Joint Distance(JD) and with four physical examination index: Finger breadth, Motor power, Pain grade, Modified Ashworth scale in 20 hemiplegic
subjects
and 20 normal person. The radiologic parameters were obtained through two X-ray view, one taken at A-P view and the other at 45°oblique view.
@ES The results obtained with the statistical analysis were as follows:
@EN 1) The mean values of the radiologic parameters in the control group were 10.4mm, 9.5mm, 42.8mm as VD1(S), VD1(E), VD2 and -2.8°26.2°as VS1, VS2 and 90.1°, 5.3mm as SR, JD. These values revealed no significant differences compared with
those
of
the hemiplegic shoulders in VS2 and SR, but showed significant differences in the other parameters.
2) The mean values of parameters in the hemiplegic shoulders were 13.4mm, 15.3mm, 35.3mm as VD1(S), VDI(E), VD2 and 6.8°, 107mm as VS1, JD. And VS1 reached 243% of the values of control group as the highest increasement and JD get to 202% as
the
second highest, VD1(E) to 161%, but VD2 decreased to 83%.
3) The sensitivity which was calculated as the percentage of the count of the subjects with abnormalvalues based on that of control group in each parameters was prooved 88.2% in JD as the highest values, 82.4% in VS1, 76.5% in VD2 and 41.2% in
VD1(S)
as the lowerest.
4) The high correlationship was found between the VD1(E) and JD(r=0.78), between VS1 and JD(r=0.65). And the correlation coefficient was 0.59 between the finger breadth and VD1(E), -0.38 between the motor power and JD, 0.48 between the pain
grade
and
VD1(E).
The results support that JD, VD1(E), VS1 and VD2 may be considered as the more sensitive and exact radiologic parameters for the measurement of subluxation and malalignment in hemiplegic shoulder, and these values may be useful in diagnosing the
shoulder subluxation and estimating the effect of any rehabilitational management.
