1、for the application of Class I BF-type part, by the host computer, the output cable and electrode three parts 2、1 group of therapeutic work unit knob to adjust the parameters of the 2-way output 3、pulse cycle T: the time between two stimulation is the pulse cycle, can be selected according to the body's rhythm of movement T, usually serious or larger muscles, muscle groups, the longer the required T value; the longer the required T value; the longer the required T value. or larger muscles, muscle groups, the longer the required T value; 4、pulse width TA, TB: the same amplitude under the pulse width value the larger the stronger the stimulation; 5、Delay time T1: it is the time when the pulse of group B appears later than the pulse of group A. For small muscles, the delay time can be shorter, and for larger muscles or muscle groups, the delay time can be shorter. For more muscles or muscle groups, it takes longer time to cause contraction, the delay time should be longer, so that the first group of pulse stimulation of muscle After the first set of pulses stimulates the muscle to contract fully, the second set of pulses will stimulate again. However, a delay time must be less than the pulse period, that is, T1 < T, otherwise, the machine will not work properly. Otherwise, the machine can not work properly; 6、Timing TimeTime: The treatment time depends on the patient's tolerance and whether fatigue occurs. 7、the principle of treatment: 8、the use of two-way pulsed electricity alternately, a group used to stimulate the spasmodic muscle tendons, another group of current stimulation of the antagonist muscle belly, pulse The pulse current can output two alternating low-frequency pulse currents week by week, and through the interactive inhibition of the two sets of currents, the spasmodic muscle relaxes, the muscle tension decreases, and the antagonist muscle increases. Through the interactive inhibitory effect of the two groups of current, the spastic muscle relaxes, the muscle tension decreases and the muscle strength of the antagonist muscle is improved, thus improving the function of the limb. 9、Adaptation range: spastic paralysis, mild paralysis after cerebrovascular accident, cerebral palsy in children, spastic paralysis caused by postpartum, multiple hardening chemical paralysis, spastic paralysis caused by cerebral and spinal cord trauma, Platinum Dickinson's disease, patients with high muscle tone caused by other diseases.
