Characterization of neuropathic pain in Cuban epidemic neuropathy
Keywords:
Polyneuropathies, Pain Clinics, Pain Measurement, CubaAbstract
Epidemic neuropathy in Cuba has been perhaps the largest of its kind reported for a non-infectious neurological disease in the past century and also among the most studied, at least in its beginnings, but no major research has been done to support the behaviour of this epidemic over time.
Aim: to characterize the neuropathic pain in the Cuban epidemic neuropathy at one municipality, from 1992 to 2018.
Method: a cohort study was conducted with 810 defined cases of epidemic neuropathy in Manzanillo, Cuba, starting from 1992 to December 2018. Two standardized instruments were applied: the pain scale and the McGill questionnaire for pain. Both instruments showed good internal consistency as determined by Cronbach’s Alpha.
Results: the comparison of proportions and mean values in each of the variables of the pain scale indicated that most patients reported having only one type of pain at all times, of medium intensity, and the McGill questionnaire provided a description of the semiographic characteristics of pain. Both instruments related to items reflected similar pain characteristics, and all Pearson’s correlation coefficients were significant for p < 0.01.
Conclusions: McGill’s questionnaire and the pain scale are useful tools to characterize the neuropathic pain.
