瘫痪患者上肢控制的复杂性给康复工程师、矫形师/假肢师或其他人带来了巨大的挑战。然而，为了简单起见，研究人员可以将残疾手臂运动的问题视为一系列具有最小枢轴和最小重力的连杆。此外，当自由度从四个减少到三个，就像本研究的情况下，那么一些日常功能可以通过使用简单的支架和夹板，外部和内部供电。在我们设计的混合式手臂矫形器（HAO）中，我们强调简单和用户的积极贡献。该矫形器充分利用了轮椅框架，而不改变其轮廓。HAO提供单自由度的身体动力肩外展和肘屈曲。一个电机驱动的手腕旋后和三关节夹爪捏提供其余两个自由度。
The complexity of upper extremity control of the paralyzed patient offers a great challenge to the rehabilitation engineer, orthotist/prosthetist, or others. However, researchers can approach the problem of disabled arm motion, for the sake of simplicity, as a series of links with minimum pivots and minimum gravitational forces. In addition, when the degrees of freedom are reduced from four to three as in the case of this study, then some daily functions can be achieved by using simple braces and splints that are powered externally and internally. In our design of a hybrid arm orthosis (HAO), we emphasized simplicity and active contribution of the user. The orthosis takes full advantage of the wheelchair frame without changing its profile. The HAO offers body powered shoulder abduction and elbow flexion of one degree of freedom. A motor-powered wrist supination and three-joint jaw chuck pinch offer the remaining two degrees of freedom.
