Efficacy of Electromyographic Biofeedback, Aerobic Exercise and Stretching in Fibromyalgia.

The Chattanooga Intelect Advanced model was used with the surface EMG for 2 independent channels. The patient can observe on the screen as columns of varying their height in the function of the degree of muscular tension. Each session was configured as follows. First, a 2 minute period for adaptation and then we continue with a 2 minute period to establish the baseline. After that, a 7 minute training trial session to reduce the muscle tension as well as a pause of about 2 minutes. Then, it continued with two more trials of 7 minutes interleaved with another 2 minute break. Thus, the whole training lasts 29 minutes approximately. The pauses between the individual trials were intended to recover the baseline level to carry out a new trial which will start from a higher level of EMG.

Aquatic Exercise program (Biodanza exercises) was carried out in a swimming-pool with a water temperature of approximately 29 ° C, preceded by a shower at a temperature of about 33-35 °C. Each session lasts an hour and they will held twice a week (Monday and Wednesday) during a period of time of three months (12 weeks).
