Abstract
The purposes of this study were to: (1) describe the lateral pelvic tilt (pelvic motion in the frontal plane) during gait in subjects with hemiplegia; (2) examine the relationship of the peak amplitude of lateral pelvic tilt during ambulation and during the single limb stance test; and (3) examine the relationship between the timing of the gluteus medius muscle and the peak amplitude of lateral pelvic tilt. Eight ambulatory hemiplegic subjects (4 right-and 4 left-side involvements; 2 females and 6 males) participated in this study. The average age was 58.88 years (ranging from 55 to 67 years old). The lateral pelvic tilt was monitored by a video camera positioned in front of the subjects during the single limb stance test and during ambulation. A second video camera positioned to the side of the subject recorded the stride length. Two foot switches placed under the heels recorded the gait cycle duration during walking trials. Surface electromyographic activity of bilateral gluteus medius muscles was monitored simultaneously with the kinematic data during ambulation. The results of this study revealed that the lateral pelvic tilt during ambulation for hemiplegic subjects was complex in wave form and asymmetrical between the left and right sides. The peak amplitude of lateral pelvic tilt during the single limb stance test was not related to that during ambulation in hemiplegic subjects. A multiple regression analysis showed that, on the unaffected side, the peak amplitude of lateral pelvic tilt during ambulation could be estimated by both the peak amplitude of lateral pelvic tilt during the single limb stance test and the normalized burst duration of the gluteus medius muscle. This relationship, however, was lost in the affected side of the hemiplegic subjects. The results of this study suggested that lateral pelvic tilt be complex in the hemiplegic subjects and it can be analyzed with the use of a video camera in the clinical settings.
