Wstęp. Wśród metod fizjoterapii stosowanych w zespołach bólowych kręgosłupa znajduje się magnetoterapia. Wielu spośród pacjentów z zespołem bólowym kręgosłupa cierpi na nadciśnienie tętnicze (NT). Wpływ pola magnetycznego (PM) na ciśnienie tętnicze krwi (RR) jest nie do końca poznany i często budzi obawy przed stosowaniem tego rodzaju terapii u pacjentów z nadciśnieniem tętniczym. Celem pracy jest ocena wpływu zabiegów magnetoterapii stosowanej w zespołach bólowych kręgosłupa lędźwiowo-krzyżowego na wartości ciśnienia tętniczego i tętna u pacjentów z rozpoznanym i leczonym nadciśnieniem tętniczym (NT) oraz u chorych bez NT. Materiał i metody. Do badania zakwalifikowano 60 chorych z zespołem bólowym kręgosłupa lędźwiowo-krzyżowego, których podzielono na 2 grupy w zależności od współistnienia NT. U wszystkich pacjentów wykonywano zabiegipolem magnetycznym o następujących parametrach: indukcja magnetyczna 9 mT, częstotliwość zmian natężenia pola magnetycznego 40 Hz, czas impulsu 0,5 s, kształt pola prostokątny. U każdego pacjenta wykonywano czterokrotnie pomiar RR oraz tętna: przed, w połowie czasu, po, oraz 10 min. po wykonanym zabiegu. Wyniki. W grupie 1 obserwowano wyższe wartości RR przed, w trakcie i po zabiegu. Stwierdzono istotne zmniejszenie RR i zwolnienie tętna w trakcie zabiegów magnetoterapii w obu grupach. Nie zaobserwowano trwałych zmian RR po 10 zabiegach magnetoterapii. Wnioski. 1. W trakcie zabiegów magnetoterapii dochodzi do istotnego spadku RR skurczowego i tętna u chorych z NT i bez NT. 2. Ciśnienie rozkurczowe w trakcie zabiegów magnetoterapii ulega obniżeniu u chorych z NT i bez NT. 3. Obniżenie skurczowego ciśnienia tętniczego i tętna podczas zabiegu magnetoterapii utrzymuje się po 10 minutach od zakończenia zabiegu w grupie chorych z NT. 4. Magnetoterapia powoduje istotne podwyższenie ciśnienia rozkurczowego krwi po 10 minutach od zakończenia zabiegu w grupie z NT i bez NT. Długość trwania takiego efektu wymaga jednak potwierdzenia w kolejnych badaniach.

Background: Magnetotherapy is one of the methods applied in the treatment of back pain syndromes. Many patients with back pain syndromes suffer from arterial hypertension (AH). The influence of magnetic fields (MF) on blood pressure is not clearly recognized and its application in patients with arterial hypertension causes some concern. The aim of the study was to assess the influence of magnetotherapy applied in patients with lumbar and sacral back pain syndromes on blood pressure and pulse rate in patients diagnosed with arterial hypertension and treated for it and those without hypertension. Materials and methods: 60 patients (pts) with lumbar and sacral back pain syndromes were included in the study. The patients were divided into 2 groups depending on the coexistence of hypertension. Magnetic fields procedures(magnetic induction 9 mT, frequency 40 Hz, impulse time – 0,5 s, impulse shape - rectangular) were performed in every patient. Blood pressure and pulse rate were measured 4 times in every patient: before, half time, after and 10 minutes after the procedure was completed. Results: Higher blood pressure measurements before, during and after the procedure were observed in group 1. Significant blood pressure and pulse rate decrease during magnetotherapy procedures was observed in both groups. Reduction of blood pressure was not observed after 10 procedures. Conclusions: 1. In the course of magnetotherapy procedure a significant decrease in systolic BP and pulse is observed in patients with hypertension and without AH. 2. Diastolic blood pressure is reduced during magnetotherapy in patients with hypertension and without AH. 3. The reduction in systolic BP and pulse lasts up to 10 minutes after the end of magnetotherapy procedure in patients with hypertension. 4. Magnetic field causes a significant increase in diastolic BP 10 minutes after the end of the procedure in the group with AH and without AH. The duration of this effect, however, requires confirmation in further studies.

Objectives The aim of this study was to investigate whether the restriction in neck rotation and increased neck muscle tension could be causally related to vertigo and dizziness. Material and Methods Seventy-one patients reporting vertigo and/or imbalance were divided into 2 groups: 45 subjects with unilateral restriction (R+) and 26 without restriction (R–) of cervical rotation and muscle tension in the clinical flexion-rotation test. The normal caloric test was the inclusion criterion. The control group comprised 36 healthy volunteers with no history of vertigo. The vestibulo-ocular reflex (VOR) and the cervico-occular reflex (COR) were measured through the videonystagmography (VNG) sinusoidal pendular kinetic test in the conditions of not inactivated head and immobilized head, respectively. The VNG-head torsion test (VNG-HTT) nystagmus was recorded. Results Among the reported complaints, neck stiffness, headaches and blurred vision were more frequent in the R+ group than in both the R– group and the control group. VNG revealed an increased COR gain and the presence of VNG-HTT nystagmus in the R+ group only. Similarly, only in the R+ group a positive relationship between COR and VOR was observed. Conclusions Patients with asymmetric restriction in neck rotation and increased neck muscle tension reveal the tendency to have an increased response of the vestibular system, along with co-existing COR upregulation. Further research is needed to investigate the relationships between the activation of cervical mechanoreceptors and dizziness pathomechanisms. Int J Occup Med Environ Health. 2019;32(5):723–33
