Recent evidence suggests that whole-body cryostimulation (WBC) may be beneficial for patients with fibromyalgia (FM), but little is known about the duration of such effects. The purpose of this study was to verify the duration of clinical-functional benefits after one cycle of WBC. We conducted a follow-up study on the medium and long-term effects of WBC on well-being, use of pain-relieving/anti-inflammatory medications, pain level, fatigue, sleep quality, and psychological aspects such as mood and anxiety. Twelve months after discharge, we administered a 10 min follow-up telephone interview with FM patients with obesity who had undergone ten 2 min WBC sessions at -110 °C as part of a multidisciplinary rehabilitation program (n = 23) and with patients who had undergone rehabilitation alone (n = 23). Both groups reported positive changes after the rehabilitation program, and similar results regarding fatigue, mood, and anxiety scores; however, the implementation of ten sessions of WBC over two weeks produced additional benefits in pain, general well-being status, and sleep quality with beneficial effects lasting 3-4 months. Therefore, our findings suggest that adding WBC to a rehabilitation program could exert stronger positive effects to improve key aspects of FM such as general well-being, pain level, and sleep quality.
