What is one method used to assess the efficacy of electrical stimulation therapy?

Evaluating muscle strength is a key method used to assess the efficacy of electrical stimulation therapy. This approach is effective because the primary goal of many electrical stimulation treatments is to improve muscle function, strength, or coordination. By measuring changes in muscle strength before, during, and after the course of therapy, practitioners can determine the effectiveness of the stimulation in achieving these therapeutic goals.

Other methods, such as tracking patient weight, measuring skin temperature, or monitoring heart rate, do not directly relate to the primary outcomes that electrical stimulation aims for. While these metrics can provide information about a patient's overall health and responses to treatment, they do not specifically indicate the success of the electrical stimulation therapy in terms of muscle function enhancement.
