Hi Wendy, am twitching big time, GP delay in EMG, i have done private emg, he states occassional polyphasic unit in calfs and right bicep, almost all muscles tested had mildly reduced interference pattern also chronic denervation left tricep, am worried and not sure, any ideas of what occasional polyphasic means? or what steps should i take, mainly twitching also toe weakness, i feel a bit uncordinated when walking but stress is a big factor. Thanks
