I will just paste their conclusions from two EMG tests:

1 test:
Elektrophysiol. findings: Neurographically, regular sensory and motor potentials in all examined nerves of the upper limb. In EMG only in the muscles supplied by the radial nerve there are signs of chronic neurogenic alterations without evidence of pathological spontaneous activities; no fasciculations demonstrated reliably in EMG.
Conclusions: Suspected chronic neurogenic damage to the muscles supplied by the right radial nerve; no reliable evidence of plexus lesion or radiculopathy.


2 test:

Elektrophysiol. findings: EMG found only in first dorsal interosseous muscle one-time path. Spontaneous activity in the form of PSW, here (also, presumably, in M. abductor pollicis brevis right) also short fasciculations; furthermore, slightly increased polyphasic rates in all examined muscles, increased amplitudes of the MUAPs and reduced interference pattern (at partially submaximal tension).
Conclusions: Also in the hand muscles supplied by the ulnar nerve and median nerve, there are signs of chronic neurogenic alterations and a slight indication of acute denervation in this area; findings thus go beyond an isolated radial nerve lesion.
