Electro diagnostic methods are used to initially detect the degree of damage and to monitor the therapy process for peripheral pareses. In physical therapy, in particular the so called I/T curve has established itself, providing substantial and relatively exact results on the one hand while being very costly and time consuming in its realization. Because it is easy and quick to implement, the determination of the so called “accommodation quotient“ (ACC) has proven to be of value as a means of electro diagnosis in the context of NMEPS and NMEAS. The diagnosis is based on the physiological phenomenon of accommodation ability that shows significant differences between damaged and intact motor nerves: a damaged/ denerved nerve-muscle system suffers losses of accommodation ability or even loses it completely. When stimulated with adequate electrical pulses, it for this reason reacts even at considerably lower amperage then a healthy one. The varying accommodation ability does not only form the basis for the accommodation quotient as a quantitative function check, but also for selecting the electrical pulses appropriate for therapy. vocaSTIM®-Master has a menu to determine the accommodation quotient conveniently, and additionally offers the possibility to operate the device via foot switch in order to have your hands free for the laryngoscopy needed at the same time.

In general, the electrotherapy treatment unit with vocaSTIM® consists of two sequences: the so called preheating with appropriate current types for promoting blood circulation the actual neuromuscular electro-phonatoric/ electro-articulatory stimulation with appropriate pulses (NMEPS/ NMEAS)
