Abstrakt		Single fibre EMG is a highly sensitive method for the diagnosis of neuromuscular transmission disorders. The neuromuscular jitter, related to safety margin of the neruomuscular junctions (NMJs) can be measured either in voluntarily contracting muscle or during electrical stimulation of motor axons. In experienced hands, both techniques are equally reliable. The "stimulation technique" is easier to learn and perform, is slightly more accurate and offers the possibility of studying neuromuscular transmission at discharge rates outside the physiological range, which is helpful in differentiating between the pre- and postsynaptic disease. The "volitional technique" avoids the pitfall of inadvertent threshold stimulation which produces false abnormal jitter and blocking, but it requires full patient's cooperation. This paper addresses some apparently unsettled issues presented in recent publications.
