Objective : To investigate objectively the postoperative improvement of gait disturbance in patients with cervical myelopathy through a gait analysis. Patients and Methods : Ten patients who underwent cervical decompression and fusion for cervical myelopathy caused by spondylosis, OPLL, or concomitant hypertrophy of ligamentum flavum were studied. Preoperatively, gait disturbance was present in all patients. The patients were evaluated by gait analysis using three dimensional motion analyzer to collect data of linear and kinematic parameters before surgery, 1 week and 3 months after surgery. Statistical analysis of the related pre-and post-operative data were performed. Results : In the linear parameters, average value of cadence, walking speed, stride length, step time, width and double support were increased postoperatively compare to preoperative value. In the kinematic parameters, average value of knee flexion during initial swing phase, plantar flexion of ankle and range of motion of hip joint were increased as well. These differences were statistically significant(p<0.05). Conclusion : This study suggests that gait analysis can be used as a method of quantitative analysis of postoperative gait improvement in patients with cervical myelopathy.

Total hip replacement arthroplasty(THA) is widely used to the patients with avascular necrosis(AVN) or degenerative arthritis(DA) to relieve pain and to obtain the recovery of function. Beside pain relief, patients want improvement in gait pattern, which is related with leg length discrepancy, range of motion, and muscle power. Accurate analysis of the recovery of gait after THA is almost impossible by the clinical observation. Therefore gait analysis is the answer for the identification of the factors related to the recovery of patients after the operation. This study was undertaken in an attempt to evaluate the gait recovery of 16 patients after unilateral THA with the scoring system using several gait parameters(single support time, walking speed, pelvic obliquity, hip motion), which was called as the gait score and to compare with Harris hip score system. We measured the gait score and the Harris hip score before and at one year after THA, and also measured the gait score in fourteen healthy persons. We compared the gait score preoperative, postoperative(POD) one year and fourteen healthy persons gait score, and also compared the gait score system with the Harris hip score system. The results were as followed: In normal control group, single support time was 38.6+-1.5, walking speed 9.4+-0.7, pelvic obliquity 4.9+-0.0, hip motion 42.3+-3.6, and total score 95.2+-4.8. Postoperative gait scores were significantly improved to 33.8+-2.7 of single support time from preoperative 23.3+-3.5, 6.8+-1.5 of walking speed from preoperative 3.6+-0.9, 4.4+-1.1 of pelvic obliquity from preoperative 2.2+-0.1, 32.9+-4.5 of hip motion(flexion-extension) from preoperative 23.8+-3.6, and 78.9+-5.3 of total score from preoperative 52.9+-4.8(P<0.05).
