Which is NOT an effect of electric muscle stimulation?

The option referring to stimulated muscle growth is the correct choice because electric muscle stimulation primarily serves therapeutic purposes such as pain relief, muscle relaxation, and improving blood circulation rather than directly causing muscle hypertrophy, which is the increase in muscle size. While muscle stimulation can enhance muscle endurance and strength to some extent, it does not inherently promote growth like traditional resistance training does.

Electric muscle stimulation techniques are effective in reducing edema by enhancing lymphatic drainage and blood flow, helping to alleviate swelling. They also help to relax muscle spasms and can promote the recruitment of muscle fibers, thereby improving muscle function and facilitating rehabilitation. However, while these functional benefits are valuable in clinical practice, actual muscle growth generally requires progressive overload through traditional exercise routines, rather than reliance solely on electrical stimulation.
