运动感缺陷（肢体位置和运动感觉）通常限制感觉运动功能及其在神经运动损伤后的恢复。提供合成动觉反馈的感觉替代技术可能会重新建立或增强动觉受损患者目标导向行为的闭环控制。作为实现这一目标的第一步，我们评估了正常人使用振动触觉感官替代来增强稳定和到达任务的能力。通过两个实验，我们比较了两种形式的补充反馈——肢体状态信息或手部位置误差——在消除手部位置漂移方面的客观和主观效用，这种漂移在消除视觉反馈后的稳定任务中自然产生。实验1对肢体状态反馈的编码进行优化；最好的形式包括手的位置和速度信息，但更倾向于位置反馈。通过对比实验2中最优肢体状态反馈和手部位置误差反馈，我们发现这两种编码方案都能够增强无视觉情况下的稳定性和到达性能。然而，错误编码产生了更好的结果-客观和主观-由于它包含额外的任务相关信息。这项研究的结果已经确立了两种形式的振动触觉动觉反馈在增强神经正常人群的手臂和手的稳定和伸展动作方面的直接效用和相对优点。这些发现可以指导未来振动触觉感觉替代技术的发展，以改善神经运动损伤后的感觉运动功能，这些幸存者保留了运动能力，但在其受影响更严重的手臂中缺乏本体感觉完整性。
Deficits of kinesthesia (limb position and movement sensation) commonly limit sensorimotor function and its recovery after neuromotor injury. Sensory substitution technologies providing synthetic kinesthetic feedback might re-establish or enhance closed-loop control of goal-directed behaviors in people with impaired kinesthesia. As a first step toward this goal, we evaluated the ability of unimpaired people to use vibrotactile sensory substitution to enhance stabilization and reaching tasks. Through two experiments, we compared the objective and subjective utility of two forms of supplemental feedback – limb state information or hand position error – to eliminate hand position drift, which develops naturally during stabilization tasks after removing visual feedback. Experiment 1 optimized the encoding of limb state feedback; the best form included hand position and velocity information, but was weighted much more heavily toward position feedback. Upon comparing optimal limb state feedback vs. hand position error feedback in Experiment 2, we found both encoding schemes capable of enhancing stabilization and reach performance in the absence of vision. However, error encoding yielded superior outcomes - objective and subjective - due to the additional task-relevant information it contains. The results of this study have established the immediate utility and relative merits of two forms of vibrotactile kinesthetic feedback in enhancing stabilization and reaching actions performed with the arm and hand in neurotypical people. These findings can guide future development of vibrotactile sensory substitution technologies for improving sensorimotor function after neuromotor injury in survivors who retain motor capacity, but lack proprioceptive integrity in their more affected arm.
