Background: Although, there have been many reports on the kinematic characteristics of lower extremities in hemiplegic patients, the investigation of trunk motion in hemiplegic patients during gait is rare. Since good trunk motion is one of the essential elements of effective walking, we investigated the kinematic characteristics of trunk motion in hemiplegic patients compared to those in healthy adults using a three-dimensional motion analyzer.
Methods: Twenty-three hemiplegic patients and twenty healthy control subjects were included in this study. Kinematic data of trunk movement and temporospatial parameters were obtained using a three-dimensional motion analyzer (Vicon 370 Motion Analysis System).
Results: Increased anterior tilt, the abducted and externally rotated angles of the trunk, increased anterior tilt, the adducted and externally rotated angles of the pelvis were significantly noted in hemiplegic patients compared with those of normal controls. The range of motion of the trunk in the sagittal, coronal, and transverse planes in hemiplegic patients was also significantly greater than that for normal controls. Among all trunk and pelvic kinematic parameters, the range of motion of the trunk in the transverse plane was the most significant factor influencing walking speed in hemiplegic patients; however, the range of motion of the pelvis in the coronal plane was the most significant factor in normal controls.
Conclusion: The trunk motion in hemiplegic patients exhibited typical kinematic characteristics during walking compared with those in healthy normal adults. These findings may be useful as baseline data for studies of hemiplegic gait. (Korean J Stroke 2007;9:128-133)
