 We developed a methodology that can identify individual motor unit firings from the Hoffman, H, reflex recorded by surface high density electromyography, HDMG. This method was then tested on synthetically generated HDMG signals, as well as on experimental H reflexes recorded from the soleus muscle of 12 participants. The results showed that the methodology had high accuracy in identifying individual motor units, especially when the signal contained a large number of MUs with low latency variability.
