Surface electromyography (sEMG) is generally considered by neurologists as an unacceptable diagnostic tool for examination of changes in the activity of muscle motor units in patients with non-specifi c back pain. The aim of this review is to demonstrate the usefulness of neurophysiological findings for the application of sEMG in differentiation of root-conflict and non-root-conflict sources of muscle pathologies with pain as the main symptom. In the first experiment carried out on 30 patients with clinically recognized myofascial pain, an attempt was undertaken to find out whether surface electromyographic (sEMG) readings during relaxation and maximal contraction revealed differences in the activity of muscles with or without trigger points (TrPs) detected by palpation. In the second experiment carried out on 40 office workers similar methodologies of clinical and neurophysiological examination were used, however, with the aim to verify a hypothesis about the dysfunction of cervical and shoulder girdle muscle motor units as the cause of cervicogenic headache (CEH). The results of both experiments led to the following conclusions: 1. Surface EMG performed at rest and during maximal contraction is a precise diagnostic tool that can be used for detection of changes in the activity of motor units in patients with myofascial pain syndrome and cervocogenic headache; 2. Surface EMG readings at rest, with an amplitude exceeding 25μV, may be helpful for evaluation of increased muscle tension, which leads to a decrease of the activity of muscle motor units during maximal contraction.

Five fractions of phenolic compounds were obtained from the extract of common buckwheat seed (Fagopyrum esculentum Moench) using Sephadex LH-20 column chromatography with methanol as a mobile phase. The total phenolics content ranged from 19.8±1.5 (fraction I) to 164±2.2 mg (+)-catechin eq/g (fraction IV). The profiles of phenolic acids and flavonoids in the fractions were analysed using RP-HPLC-DAD. The antioxidant activity was tested as ABTS^+ and DPPH scavenging activity and capability to reduce the Fe(III)/2,4,6-Tris(2-pyridyl)-s-triazine complex to the ferrous form. Results were expressed as Trolox equivalent antioxidant capacity (TEAC), IC50 and ferric reducing antioxidant power (FRAP) values, respectively. The highest antioxidant activity was noted for fraction IV that was predominated by flavones. TEAC, IC50 and FRAP values were: 1.47±0.01 mmol Trolox eq/g, 0.058±0.003 mg/assay and 2.18±0.05 mmol Fe(II)/g, respectively. Rutin constituted 77.7% of the compounds identified in fraction III. The antiradical activity and reducing capability of this fraction were lower compared to fraction IV, but significantly higher than in fractions I and II. The main phenolic compounds of fractions I and II were phenolic acids (caffeic, 5-O-caffeoylquinic and p-coumaric). The antioxidant activity of fraction V was similar to that of fraction III.
