Final answer:
For muscle reeducation using HVPC, the intensity should be increased to achieve a tetanic contraction, facilitating muscle strengthening and improved neural patterns.
Step-by-step explanation:
When using High Voltage Pulsed Current (HVPC) for muscle reeducation, the intensity should be increased to achieve a Tetanus response. A single twitch is a quick, single contraction resulting from a single stimulus, whereas tetanus is a state where a muscle remains contracted without any significant period of relaxation. Tetany refers to the continuous and sustained muscle contraction that happens when the motor neurons fire at high frequencies, eliminating the relaxation phase. Therefore, to effectively reeducate muscles using HVPC, the intensities should be set to elicit a tetanic contraction, which facilitates the strengthening of the muscles and improves the neural connection for muscle contraction patterns.
