Analysis of motor control based on somatosensory information and development of measurement system

当我们操纵工具或物体时，中枢神经系统从手中的触觉传感器和肌肉中的本体感受信号接收力信息。这种体感信息不仅对预测我们的运动状态至关重要，而且对运动规划也至关重要。为了灵巧地控制工具，我们必须在与物理环境的交互中执行我们的运动，从而产生适当的力轨迹。在这里，我们专注于规划力交互式任务的力感信息的作用。为了验证人类使用手掌和手指的触觉信息进行规划的说法，我们使用曲柄旋转任务进行了实验和模拟数据之间的比较。我们的研究结果表明，测量和预测数据之间的密切匹配。

When we manipulate tools or objects, the central nervous system receive force information from tactile sensors in hand and from proprioceptive signals in muscles. Such somatosensory information is crucial not only for predicting states of our movements but also for motor planning. To control tools dexterously we must execute our movements in interaction with the physical environment resulting in an appropriate force trajectory. Here we focus on the role of force sense information on planning a force interactive task. To test the claim that human use tactile information of palm and fingers for planning, we conducted comparisons between experimental and simulated data using a crank-rotation task. Our results show a close matching between the measured and predicted data.
