Each voluntary movement, including inspiration, is preceded by movement-related cortical potential (MRCP) that can be recorded from the scalp. Our aim was to explore whether the inspiratory-(sniffing)-related cortical potentials (SRCPs) and index-finger-flexion MRCPs (FFRCPs) can be used as markers of cortical involvement in ALS. No statistically significant difference was found between the MRCP amplitudes of the ALS patients and the control subjects. However, patients with more severely affected upper limb functions generated smaller FFRCPs and those with more affected respiratory functions generated smaller SRCPs. Excessively high FFRCPs were associated with better while excessively low FFRCPs with worse scores on some of the clinical measures of the upper limb function. Our results demonstrate MRCPs, may be useful to determine the spectrum of motor control changes in this population.

COBISS.SI-ID: 28931033In diagnostics of hypercapnic respiratory failure we often use also respiratory neurophysiologic methods. In 20 patients with chronic obstructive pulmonary disease we demonstrated efficient separation of neuromuscular and pulmonary causes of respiratory failure. Patients with chronic obstructive pulmonary disease had even larger amplitudes of motor responses on phrenic nerve stimulation than controls.
