The electric shock stimulates a nerve and causes contraction of one or more muscles located in close proximity to the nerve. The stronger the stimulus, the greater the muscle contraction force. Rimba has developed a wide range of accessories that can be connected to any rimba powerbox. The accessory electrodes have different shapes and sizes, matched to the erogenous zones of men and women.
