title: Neurophysiological assessment of the electrostimulation procedures used in stroke patients during rehabilitation.
abstract: The aim of this study was to evaluate the effectiveness of the associated electrotherapeutical and kinesiotherapeutical treatment in patients after ischemic stroke (N=24), mainly by means of neurophysiological tests. All patients underwent the same 20 days of neurorehabilitation procedures. Particular attention was paid to three-stage modified electrotherapy procedures such as: oververtebral functional electrical stimulation (FES), transcutaneous electrical nerve stimulation (TENS) and the alternate neuromuscular functional electrical stimulation (NMFES) of antagonistic muscles of the wrist and the ankle (N=16). Electrotherapy was supplemented with kinesiotherapeutic (mainly PNF) procedures acting as an amplifier. Clinical assessment included muscle tension (Ashworth's scale), muscle force (Lovett's scale) and reflex scoring at wrist and ankle. However, the effectiveness of the procedures was measured by the assessment of results in complex and repetitive, bilaterally performed global electromyography (EMG) and electroneurography (ENG; M-wave studies). The statistical analysis obtained from results in clinical and neurophysiological examinations suggested that the dorsiflexion of wrist and ankle was improved in the majority of patients who took part in this study. EMG and ENG examinations showed that 20 days of therapy improved both activity in muscle motor units on the more paralyzed side (mainly within upper extremities) and to a lesser degree in the transmission of efferent impulses within motor fibers of nerves. The results obtained suggest that patients after ischemic strokes never show an isolated unilateral disability in motor functions. No definite similarities between the results of clinical and neurophysiological studies were found, which may suggest greater accuracy of the neurophysiological evaluation.
