To record the displacement of the trunk during gait easily, we placed a portable accelerometer on the subject's back. We examined the reproducibility of the testing and compared it with the measurement of the ground reaction forces with the force plates and our simple motion analysis system using three laser pointers and a video camera. Subjects were five healthy adults and one paraplegic patient. The paraplegic patient whose functional level was T10-11 can walk independently with Lofstrand crutches and a hip-knee-ankle-foot orthosis system with a medial single hip joint (Walkabout®). The subjects_ who were equipped with the accelerometer at the back of the trunk were directed to walk twice on the force plates at a comfortable speed. The test-retest cross-correlation coefficients ranged from 0.46 to 0.94. The cross-correlation coefficients between the accelerograms from the accelerometer placed on the back and the ground reaction forces ranged from 0.73 to 0.93. With the paraplegic patient, we measured the displacement of the trunk during walking with our motion analysis system. When we added the functional electrical stimulation (FES) to the Walkabout® system, he could walk faster and the displacement of the trunk in the horizontal plane significantly decreased. The peak-to-peak amplitudes of the accelerographs in the horizontal plane did not differ with or without FES. These results suggest that the gait analysis using a portable accelerometer placed on the back and our motion analysis were valid for clinical use.
