What is Vibrational Therapy? During a treatment, the acupuncturist may use a set of tuning forks to treat patients.  Since Qi is considered a vibration, the use of sound at different frequencies can enhance the results of treatment.  This is also ideal for small children who may be afraid of needles.  The tuning forks  have an interesting effect even at the emotional level of illness.  Patients may experience various feelings or remember past events through the use of tuning forks.
