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)
The healing of a cutaneous wound is accompanied by endogeneous electrical phenomena. Not knowing whether they represent merely a side-effect of the physiological processes which take course during healing or whether they play a much more important role as mediators of healing, externally applied electricity was examined as a therapeutic tool for the(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)
Subjects with spinal cord injury are often distressed by pressure sores, which usually appear after prolonged pressure (wheelchair, bed) across the soft tissue which has already lost sensibility and has diminished microcirculation. The healing ability and its dynamics depend on the state of the subject's overall health. Consequently, evaluation of a(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)
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)
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)
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)
The effects of long-term electrical stimulation on reflex hyperactivity and voluntary muscle control were studied. Eight hemiplegic patients with implanted peroneal stimulator were included. After six months of functional electrical stimulation (FES) there was a decrease of tonic activity in both tibialis anterior and triceps surae muscles. The phasic(More)
