The motivation behind this article is to demonstrate the precision and dependability of a Field Programmable Gate Array-based implementation of muscle fibre conduction velocity (MFCV) in customary unique constrictions. The framework, leveraging the DSP unit, acquires the bio signals from four different positions of the human body, including Radial Nerve, Ulnar nerve, Auxiliary Nerve, Median nerve. The information derived through Surface Electromyogram (EMG) Electrodes is depicted as a dynamic bitstreams of the signal. The latest bitstreams are subjected to an algorithm. The subjection corresponds to the correlation of the signals from similar muscle nerves, obtained through the EMG electrodes. The whole calculation framework completely works progressively on the Altera Cyclone-V FPGA. This method is better than finding the signal dependence using a silicon resonator due to its cost and tedious design of the sensors. The myoelectric (Electromyographic) signal is recorded by the electrodes set on the four different locations associated with 1550 unique contractions. The in-vivo estimations illustrate that below the equivalent trial states, in 10 test days, the framework uncovers an MFCV mean estimation of 6.60 (±) 0.42 m/s for Median nerve Position, 6.43 (±) 0.33 m/s for Ulnar Nerve Position, 6.54 (±) 0.41 m/s for Radial nerve Position and 7.21 (±) 0.49 m/s for Auxiliary Nerve Position. The values evidence decent dependability of the estimations in an eternal application. The core part of the device being MFCV estimation, upon empirical evaluations with clinical values, shows an accuracy of 97%.

使用FPGA设计,实现和估算人体4个不同位置的MFCV

本文的目的是为了证明在惯常的独特压缩条件下,基于现场可编程门阵列的肌肉纤维传导速度(MFCV)的实现的准确性和可靠性。该框架利用DSP单元从人体的四个不同位置获取生物信号,包括Rad神经,尺神经,辅助神经,正中神经。通过表面肌电图(EMG)电极得出的信息被描述为信号的动态位流。最新的比特流经过算法处理。该主观对应于通过EMG电极获得的来自相似肌肉神经的信号的相关性。整个计算框架可在Altera Cyclone-V FPGA上完全逐步运行。由于其成本和传感器的繁琐设计,该方法比使用硅谐振器发现信号依赖性更好。设置在与1550个唯一收缩相关的四个不同位置上的电极记录了肌电信号。体内估计值表明,在同等试验状态下,在10个测试日内,框架发现中位神经位置的MFCV平均估计值为6.60(±)0.42 m / s,尺神经的平均估计值为6.43(±)0.33 m / s位置,Rad神经位置为6.54(±)0.41 m / s,辅助神经位置为7.21(±)0.49 m / s。这些值证明了在永恒的应用中估计的可靠性。设备的核心部分是MFCV估计,根据具有临床价值的经验评估,其准确性为97%。
