What is the recommended placement of electrodes when applying electrical stimulation?

The placement of electrodes in electrical stimulation is crucial for effectively targeting the desired muscle group and ensuring optimal outcomes. Positioning the electrodes 1-5 cm apart and parallel to the muscle fibers allows for the current to travel seamlessly along the muscle's natural pathway. This alignment increases muscle activation and facilitates a more effective contraction.

When electrodes are placed in this manner, it enhances the stimulation of the underlying muscle fiber orientation, leading to improved therapeutic benefits such as muscle strengthening or pain relief. The relatively close proximity of the electrodes helps to create a more concentrated zone of stimulation, ensuring that the electrical current effectively engages the muscle tissue.

Other methods, such as placing electrodes only on the muscle belly or increasing their distance significantly, might not optimize the stimulation effects. For instance, scattered placement might lead to less focused stimulation and potentially diminished therapeutic benefits. Similarly, the circular arrangement does not leverage the muscle fiber alignment, which is vital for maximizing efficiency and efficacy in electrical stimulation protocols.
