Simple and inexpensive instrumentation required for pendulum testing of spasticity is described. It is based on the use of an electrogoniometer and tachometer. Eight parameters are extracted from the goniogram and the tachogram to evaluate the degree of spasticity. The correlation coefficients are calculated to determine the parameters relevant for the(More)
Electrotherapy with low-level direct current has been suggested as an effective regional cancer treatment. A great variety of electrode materials, their placement with respect to tumor (i.e. electrode configurations) current levels and therapeutic schedules have been employed to date. In our paper the impact of electrode materials and configurations was(More)
The effect of afferent cutaneous electrical stimulation on the spasticity of leg muscles was studied in 20 patients with chronic hemiplegia after stroke. Stimulation electrodes were placed over the sural nerve of the affected limb. The standard method of cutaneous stimulation, TENS with impulse frequency of 100 Hz, was applied. The tonus of the leg muscles(More)
Seven spinal cord injured (SCI) patients with clinical signs of knee-joint spasticity were tested with the Wartenberg pendulum test and an electrogoniometer. All patients were subjected to four channel rhythmical electrical stimulation of the knee muscles for three consecutive days. In five patients some improvement of spasticity was achieved. No increase(More)
Functional movements can be restored after stroke by portable neuroelectric stimulator controlled by the patient. This field of activity is called functional electrical stimulation (FES). A common example of FES is electric stimulation of the peroneal to prevent dropfoot. A more sophisticated multichannel enables stimulation of more than one paralyzed(More)
To study the efficacy of electrical stimulation in treating spasticity of six spinal cord injured patients, transcutaneous electrical nerve stimulation (TENS) was applied to the dermatomes belonging to the same spinal cord level as the selected spastic muscle group. Spasticity was assessed in knee extensors by a pendulum test in which the knee joint angle(More)
A model of hemiplegic spasticity based on electromyographical and biomechanical parameters measured during passive muscle stretching is presented. Two components of spasticity can be distinguished--phasic and tonic. This classification depends on the pattern of stretch reflex activity which can be either phasic or tonic as well as on the muscle(More)
Notwithstanding several past clinical studies demonstrating the beneficial impact of electrical stimulation with steady direct current on the healing of chronic cutaneous wounds, the basic mechanisms underlying its effects on regenerative processes remain w be elucidated and the stimulation regime optimized. In the present study, an attempt is made towards(More)
Change in muscle force in healthy subjects due to electrical stimulation was accomplished with rectangular and sinusoidal currents. The pulse width of rectangular stimuli was 0.3 ms and repetition frequency was 25 Hz. The frequency of sinusoidal stimuli was 2 500 Hz, chopped by a 25 Hz rectangular signal. Thirteen healthy subjects were involved in the study(More)
Antitumor effectiveness of cisplatin can be improved either by intratumoral administration of the agent or by increased drug delivery into the cells by exposing the tumor to short intense electric pulses. Electric pulses increase plasma membrane permeability (electropermeabilization) of tumor cells and thus allow the chemotherapeutic agent intracellular(More)
