Sequential stimulation devices combine interferential current and muscle stimulation features. The goal of the muscle stimulation component is to restore muscle function and prevent disuse atrophy. For example, the RS-4i Muscle Stimulator (RS Medical, Vancouver, WA) is used in two phases because only one modality may be operated at a time. First, the device delivers an interferential current for muscle pain relief. Next, the device's muscle stimulation feature is applied to treat the affected muscle.
Interferential and sequential stimulation devices require constant professional supervision for proper operation.
