Which of the following is NOT an approved treatment intervention for cramps?

Gloves filled with hot water are not an approved treatment intervention for cramps. Effective interventions focus on methods that directly alleviate cramps through either promoting muscle relaxation or improving hydration and electrolyte balance. Using warm compresses can help relax muscle tissue, while stretching exercises are widely recognized for their effectiveness in relieving muscle tightness. Hydration with electrolyte solutions is crucial for maintaining muscle function, and addressing dehydration can prevent cramps from occurring. Therefore, while warm compresses, stretching, and proper hydration are beneficial, gloves filled with hot water do not target the underlying causes of cramps in the same way and lack endorsement as a standard treatment intervention.
