Kinematic Gait Analysis of Ramp Walking in Normal Adult

OBJECTIVE: To investigate the characteristics of ramp walking. METHOD: The sagittal kinematic and temporospatial data of ramp and level walking were obtained by a motion analyzer for ten healthy young adults. RESULTS: Compared with the values of level walking, the range of motion of ankle at all degrees for up-hill walking and the ROM of hip at 20o down-hill and all degrees for up-hill walking were significantly different (p<0.05). The peak dorsiflexion of ankle at 20o of up-hill and at 20o down-hill walking increased significantly (p<0.05) and peak plantar flexion of ankle at all degrees of up-hill walking increased significantly (p<0.05). The peak flexion of knee at 20o of up-hill walking increased significantly (p<0.05) and peak extension of knee at 20o of up-hill and down-hill walking also increased significantly (p<0.05). The peak flexion angles of hip at all degrees for up and down-hill walking were significantly different (p<0.05) and peak extension angles of hip at 10o of up-hill walking increased significantly (p<0.05). The temporospatial data showed no significant difference. CONCLUSION: Ramp walking showed a different kinematic gait pattern. So, this study may be useful to evaluate the effect of gait training on the ramp and pathologic gait patterns.

The Patterns of Spinal Deformity in Duchenne Muscular Dystrophy

OBJECTIVE: To investigate the relationships between scoliosis and kyphotic or lordotic posture in Duchenne muscular dystrophy (DMD) patients, this study explored the factors influencing the development of spinal deformity. METHOD: Twenty five DMD patients with scoliosis were conducted to roentgenographic study to obtain Cobb's angle. In addition, rotation grade of the spine, as well as the degree of kyphotic and lordotic postures were obtained using the Moe pedicle method, kyphotic index and lumbo sacral angle respectively. The data were assessed for the correlations among spinal deformities as well as the evaluation of functional state. After comprehensive rehabilitation programs for six months including scoliosis correction exercise, breathing exercise and thoracolumbosacral spinal orthosis, the effects of spinal deformity and pulmonary function were analyzed. An age-matched control group of 15 male patients with scoliosis were analyzed and compared with the experimental group. RESULTS: In the experimental group, the scoliosis angles were negatively correlated with kyphotic index (r= 0.80, p<0.01). In the control group, no correlations of statistical significance were detected among different types of spinal deformity. In addition, the rotation grade was found to be positively correlated with the scoliosis angle in the experimental group (r=0.89, p<0.01). Furthermore, the larger the scoliosis angle, the patients functional state was found to be poorer (r=0.56, p<0.01). CONCLUSION: In DMD patients, a strong correlation was found between the scoliosis and kyphotic posture. For the prevention of kyphotic posture, further study on the relevant therapeutic approach would be needed.
