For weak muscle groups, how should electrodes be positioned for optimal results?

When addressing weak muscle groups, positioning electrodes far apart with high sensitivity is considered optimal for several reasons. Placing the electrodes far apart allows for a broader coverage of the muscle area being targeted, ensuring that the electrical stimulation can effectively engage more muscle fibers. This broader placement can lead to a more functional contraction of the muscle, which is essential for strengthening and rehabilitation.

High sensitivity settings help in detecting and stimulating even a minor electrical response from the weak muscle. This stimulations can promote adaptive responses in the muscle, improving its strength and functional capacity over time. It is particularly important for weak or atrophied muscles, as a more effective stimulation can promote muscle re-education and increase motor recruitment.

In contrast, placing electrodes close together might limit the area affected by the stimulation, reducing the overall effectiveness in stimulating the desired muscle group. Low sensitivity settings would not effectively engage weak muscle fibers, thereby limiting the therapeutic effect that electrical stimulation can provide. Additionally, focusing stimulation solely on the weakest part of the muscle may neglect the engagement of surrounding supportive muscles, thus inhibiting overall functional recovery.
