Gait analysis ; Simulated stiff-knee gait ; Energy consumption
Objective: To investigate the effect of simulated stiff knee on the gait parameters. Method: Twenty healthy male adults were recruited. The temporospatial, kinematic & kinetic parameters and energy consumption were analyzed under three different conditions which were free gait, fixed knee flexion in neutral position and limited knee flexion to 30 degrees using knee orthosis. Results: When knee flexion was fixed in neutral position, the cadence and walking speed significantly decreased, and the step time, step width, O2 cost significantly increased compared to free gait. When knee flexion was limited or fixed in neutral position, the kinematic and kinetic parameters in pelvis, hip, knee and ankle joints significantly changed compared with free gait. Conclusion: Simulated stiff-knee may affect not only knee joint but also pelvis, hip and ankle joints with increased energy consumption. These findings help us to understand the compensatory mechanism and energy conservation of stiff-knee gait.
