Initially, use the Infratonic 9 on the back of the neck several times a day for 10 to 20 minutes. For the first time or two, apply the Acute setting, then move to the Balance setting. This will calm the affected area and alleviate soreness and stiffness. Continued treatment for 10 to 20 minutes several times a day will greatly reduce the muscle tension. This reduces the compress vertebrae which might otherwise cause the standard cycle of nerve impingement and inflammation, which would cause greater muscle tension. Many who have applied the Infratonic 9 soon after a whiplash injury have reported that it never turns into whiplash. Where full whiplash symptoms have already set in before Infratonic use, applying the Infratonic regularly a few times a day will gradually soften the muscles and reduce the nerve impingement and inflammation. Many have reported that this provides immediate pain relief and increased mobility, and reduces recovery time considerably.
