Pre-modulated
Interferential Current (IFC)
The function of IFC stimulation is to reduce pain, inflammation and swelling around a joint. It also can increase the circulation of an area. This type uses 2 channels of electrical current at a sensory level to interfere with the pain signals a body part is sending to the brain. The area of intersection of the nodes is given temporary relief of pain. IFC works well for pain relief because it is tollerated better by the skin which allows the current to penetrate deeper into the tissues. The therapist can set the duration of stimulation ranging from 5-15 minutes.
Pre-modulated stimulation is similar to IFC stimulation. The function of pre-mod is to decrease the pain in soft and connective tissues. This method works just like the IFC, but instead of a constant electric flow, pre-mod uses bursts of frequency. Also, pre-mod uses 2 electrodes instead of four to achieve the disruption of pain signals. The therapist can set the duration of stimulation ranging from 5-15 minutes.
High volt stimulation is typically used to decrease pain, swelling or assist in wound healing. It uses a monophasic (negative or positive) pulsed current and the pulses are delivered in a doublet. The pulse is short and doesnt penetrate very deep into the tissues. High volt can be used to stimulate new tissue production. The therapist will typically set this stimulation for about 5-10 minutes.
Russian stimulation is used to simulate a muscle contraction. There is one stimulation pad on the muscle’s insertion into the bone and another on the muscle belly. It can be used on any muscle to strengthen the contractability. This is the only type of stimulation where a strong muscle contraction is the goal. This stimulation is typically set for about 15 minutes.
