| Abstract |
Objective
To evaluate the changes of gait patterns during crossing obstacles of different heights in hemiplegic stroke patients and to compare gait characteristics with those of healthy control subjects.
Method
Subjects were 13 hemiplegic stroke patients and 9 age-matched healthy adults. Subjects stepped over obstacles with each height of 3, 8 and 13 cm. The three- dimensional gait analysis was performed. Temporospatial, kinematic and kinetic parameters were measured in both lead and trail limb. The pre- and post-obstacle distance, pre- and post-obstacle swing time and toe clearance were also measured.
Results
With increase in height of obstacles, ratio of single limb support time, angle of hip, knee flexion in swing phase and hip extensor moment increased in both lead and trail limbs. In the lead limb, post-obstacle distance and toe clearance also increased (p＜0.05). Compared with control groups, the angle of knee flexion, hip extensor and hip flexor moment and pre- and post-obstacle distance decreased significantly in the lead limb of hemiplegic patients (p＜ 0.05). In the trail limb of hemiplegic patients, the angle of hip flexion, hip flexor moment and post-obstacle distance decreased (p＜0.05).
Conclusion
Understanding strategies for adequate control and coordination of the swing limb during crossing obstacles may be the basis for the safe training of obstacle crossing in hemiplegic stroke patients. (J Korean Acad Rehab Med 2009; 33: 668-674) |
