RESUMEN
BACKGROUND AND OBJECTIVES: Self-reported psychological variables related to pain have been posited as the major contributors to the quality of life of fibromyalgia (FM) women and should be considered when implementing therapeutic strategies among this population. The aim of this study was to explore the effect of low-pressure hyperbaric oxygen therapy (HBOT) on psychological constructs related to pain (i.e., pain catastrophism, pain acceptance, pain inflexibility, mental defeat) and quality of life in women with FM. METHODS: This was a randomized controlled trial. Thirty-three women with FM were randomly allocated to a low-pressure hyperbaric oxygen therapy group (HBOTG) (n=17), who received an 8-week intervention (5 sessions per week), and a control group (CG) (n=16). All women were assessed at baseline (T0) and upon completion of the study (T1) for self-perceived pain intensity, pain catastrophism, pain acceptance, pain inflexibility, mental defeat and quality of life. RESULTS: At T1, the HBOTG improved across all variables related to pain (i.e. self-perceived pain intensity, pain catastrophism, pain acceptance, pain flexibility, mental defeat) (p<0.05) and quality of life (p<0.05). In contrast, the CG showed no improvements in any variable. Furthermore, significant differences between the groups were found in quality of life (p<0.05) after the intervention. CONCLUSIONS: HBOT is effective at improving the psychological constructs related to pain (i.e. pain catastrophism, pain acceptance, pain flexibility, mental defeat) and quality of life among women with FM.

BACKGROUND: Fibromyalgia (FM) is characterized by chronic pain and fatigue, among other manifestations, thus advising interventions that do not aggravate these symptoms. The main purpose of this study is to analyse the effect of low-pressure hyperbaric oxygen therapy (HBOT) on induced fatigue, pain, endurance and functional capacity, physical performance and cortical excitability when compared with a physical exercise program in women with FM. METHODS: A total of 49 women with FM took part in this randomized controlled trial. They were randomly allocated to three groups: physical exercise group (PEG, n = 16), low-pressure hyperbaric oxygen therapy group (HBG, n = 17) and control group (CG, n = 16). Induced fatigue, perceived pain, pressure pain threshold, endurance and functional capacity, physical performance and cortical excitability were assessed. To analyse the effect of the interventions, two assessments, that is, pre and post intervention, were carried out. Analyses of the data were performed using two-way mixed multivariate analysis of variance. RESULTS: The perceived pain and induced fatigue significantly improved only in the HBG (p < 0.05) as opposed to PEG and CG. Pressure pain threshold, endurance and functional capacity, and physical performance significantly improved for both interventions (p < 0.05). The cortical excitability (measured with the resting motor threshold) did not improve in any of the treatments (p > 0.05). CONCLUSIONS: Low-pressure HBOT and physical exercise improve pressure pain threshold, endurance and functional capacity, as well as physical performance. Induced fatigue and perceived pain at rest significantly improved only with low-pressure HBOT. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03801109.
RESUMEN
INTRODUCTION: Chronic low back pain is a pathological process that compromises the functionality and quality of life worldwide. The objective of the study was to evaluate the effectiveness of classical physiotherapy in the management of non-specific chronic low back pain. METHODS: A literature search in English electronic databases was performed from November to December of 2015. Only those studies addressing chronic non-specific low back pain by manual therapy and different types of exercises methods were included, and those, which combined acute or subacute pain with systematic reviews and clinical practice guidelines, were excluded. Studies involving cognitive-behavioral approaches were also excluded. RESULTS: 487 studies were identified, 16 were analyzed and 10 were excluded. Of the 6 studies reviewed, 5 of them achieved a moderate quality and 1 of them was of a low quality. Back School exercises and McKenzie's method were all ineffective. Osteopathic spinal manipulation proved effective when performed on the lower back and the thoracic area but only immediately after it was received, and not in the medium or long term. Massages proved effective in the short term too, as well as the global postural reeducation although ultimately this study can be considered of a low methodological quality. CONCLUSIONS: Based on the data obtained, classical physiotherapy proposals show ineffectiveness in the treatment of chronic non-specific low back pain. More multidimensional studies are needed in order to achieve a better treatment of this condition, including the biopsychosocial paradigm.
