=====Manual Methods=====
Traditional methods are based on the recording of one or more MUPs during slight muscle activation. The obtained MUPs were identified, photographed, and measured manually. All MUPs with a rise time of less than 0.5 msec and amplitude greater than 0.5 μV, with repeatable shape and amplitude at least three times, were selected for analysis. With the advent of computerized techniques, an averaging triggered by a spike was achieved. The manual method was modified by introducing a delay line and a level trigger, allowing the selection of one low-threshold MUP at a time and subsequently measuring it manually or using a computerized method.
