The treatment consisted of two sessions per week for five weeks, for a total of 10 treatments. At each session, patients received 23 min of LFSS at a 40 Hz frequency (79), delivered with the SL5 lounge from Nexneuro (USA). The power level of the sound was the same for all subjects (decibel level not measured). They were not specifically instructed to do anything other than lie back and relax. Participants experienced a mild vibrotactile sensation on their body as well as a low-level hum. No patient reported any discomfort or annoyance. Blood pressure and pulse rate were checked and documented in every session before and after the treatment while patients were on the lounge.
