Ambulation would bring many physiological and psychological benefits and getting up and walking has been a dream for paraplegia patients.The reciprocating gait orthoses (RGOs) for paraplegics particularly draws research attentions because it mimics human gait pattern.But, the high energy consumption and low walking speeds caused the frequent abandonment or the low utilization of the reciprocating gait orthoses.To improve the design reducing the energy expenditure, it requires biomechanical analysis of the pathological gait such that the gait deviations and energy consuming mechanisms can be identified and remedial means can be implemented.
The investigators hypotheses will include that there would exist an energy saving mechanism of human reciprocating locomotion based on the principle of conservation of mechanical energy.Secondly, kinematic and kinetic gait determinants could be derived from the energy saving mechanism. Finally, the control of knee joint coordinating with the hip joint movements would facilitate the gait progression and further reduce the energy consumption.
The objective of this clinical trial is to evaluate the gait of paraplegic patients with reciprocating gait orthoses and to support the investigators research in biomechanical analysis, design and control of reciprocating gait orthoses for paraplegia patients. An experiment to study the pathological gait of paraplegia patients with an existing reciprocating gait orthosis will be carried out.
