Objectives. To study diagnostic possibilities of
electroneuromyography for the definition and (or)
confirmation of fingers tenosynovitis stenosans.
Methods. The analysis of neuromyography
research results of 56 patients with this pathology which
were treated in the Regional Clinical Tuberculosis
Hospital, in the hand microsurgery department in
Donetsk within the period of 2008-2012. The patients
were divided into two groups depending on clinical stage
of the disease. The first group included 28 patients with
ligamentitis at the 2nd stage, and the second one –
28 patients at the 3rd stage. The groups did not differ
statistically in age (Student criteria, р<0,05), gender
(criteria χ2, p<0,05) and disease severity (Wilcoxon
criteria, p<0,05). To evaluate the functional state of the
flexor hallucis longus muscle one fulfilled a needle or
interferential surface electromyography
Results. The obtained results were statistically
processed using standard package of licensed
application software «Office Professional 97» of
company «Microsoft Corporation». The results were
compared according to Student and Mann-Witney-
Wilcoxon criteria. Average age norm of motor unit
potentials amplitudes value in patients at the age of 45-
65 years old is 800-1000mV, with duration 9,0-9,5ms.
In patients with the second clinical stage of the process
the average value of motor unit potentials duration was
7,7±0,03ms, and motor unit potentials amplitude was
770,5±3,2мV, and it was 6,3±0,12ms and 541,3±6,1mV
in patients with the third stage. Average polyphasy
value in patients of both groups was 23,2±0,75 % and
32,3±0,94% correspondingly. By comparison of those
values in different groups of patients we got statistically
true difference (р<0,001).
Conclusion. The motor unit potentials amplitude
decrease up to the level 700-800mV is specific for
the patients with the second stage of tenosynovitis
stenosans, and duration is up to 7,5-8,0msec, for the
patients with the third stage the values are 500-600
mV and 5,5-7,4msec correspondingly. Thus, in patients
with the seconds and the third stages of tenosynovitis
stenosans there is true difference in main neurometric
values: motor unit potentials duration and amplitude.
Electroneuromyography is an Objectives and true
diagnostic method of tenosynovitis stenosans stage.
Key words: electroneuromyography, tenosynovitis
