Which statement about the hypervolt massage device is accurate?

The statement highlighting that the hypervolt massage device is used to work on tight spots identified during the stretch session is accurate. This device employs percussion therapy to alleviate muscle tension and soreness, targeting specific areas that may require extra attention. By focusing on tight spots, the hypervolt enhances blood flow, promotes recovery, and helps in increasing flexibility, making it a valuable tool in conjunction with stretching routines.

The other statements either misrepresent the function and appropriate use of the device, such as suggesting it should only be used on bones and joints—which contradicts its purpose of aiding soft tissue treatment—or inaccurately claim that it's contraindicated during all forms of massage, which would prevent it from being used as intended. Furthermore, suggesting it must be used vigorously is not accurate, as effectiveness is more about the appropriate settings and amount of pressure rather than sheer force.
