Injury epidemiology in competing and non-competing spanish crossfit® practitioners / Epidemiología lesional en practicantes de crossfit® competidores y no competidores españoles

La falta de estudios sobre lesiones en Crossfit® en España, motiva la realización de este estudio epidemiológico descriptivo, observacional y retrospectivo, analizando la incidencia y las características de las lesiones sufridas por practicantes de Crossfit® competidores y no competidores. Se registraron las lesiones sufridas por 434 deportistas entre el 1 de enero y el 31 de diciembre de 2019. Se registraron datos sobre el número de lesiones, lesiones más frecuentes, distribución, tipo, ubicación, el momento en que ocurrieron y la causa de las lesiones que afectan el sistema musculoesquelético. La tasa de lesiones en esta población fue de 3,48 lesiones por 1000 horas de exposición al riesgo. El hombro y la zona lumbar fueron las zonas anatómicas más frecuentemente lesionadas, siendo el musculo y el tendón el tejido de asiento más habitual de las lesiones. El Powerlifting fue la actividad más lesiva. (AU)

The lack of studies on Crossfit® injuries in Spain, motivates the realization of this descriptive, observational and retrospective epidemiological study, analyzing the incidence and characteristics of injuries suffered by Crossfit® competitors and non-competitors.The injuries suffered by 434 athletes between from January 1st to December 31st 2019 were recorded. We collected data on the number of injuries, the most frequent injuries, their distribution, type, location, the moment at which these occurred and the cause of the injuries affecting the musculoeskeletal system. We found that the injury rate in this population was 3,48 injuries per 1000 hours of risk. The shoulder and lumbar area were the most frequently injured anatomical areas, with muscle and tendon being the most common seat tissue of injuries. Powerlifting was the most damaging activity.

Pain extent is associated with Central Sensitization Inventory but not widespread pressure pain sensitivity or psychological variables in women with fibromyalgia.

OBJECTIVE: To investigate the relationship between pain extent, as a clinical sign of central sensitization, and clinical, psychological, and pressure sensitivity in women with fibromyalgia syndrome (FMS). METHOD: In this study, 126 females with FMS completed demographic (age, gender, body mass index, height, weight), clinical (pain history, and pain intensity at rest and during daily living activities), psychological (depression and anxiety levels), and neurophysiological [pressure pain threshold (PPT)] assessments. The Central Sensitization Inventory (CSI) was also used to collect self-reported symptoms of sensitization. Pain extent and frequency maps were obtained from pain drawings using customized software. After conducting a multivariable correlation analysis to determine the relationships between variables, a stepwise linear regression model analysis was performed to identify variables associated with pain extent. RESULTS: Pain extent was positively associated with age (r = 0.17), years with pain (r = 0.27), pain during daily life activities (r = 0.27), and CSI (r = 0.42) (all p < 0.05). The stepwise regression analysis revealed that 27.8% of the pain extent was explained by CSI, age, and years with pain. CONCLUSIONS: This study found that larger pain extent was associated with self-reported outcomes, i.e. CSI, but not neurophysiological outcomes, i.e. PPTs, of sensitization in women with FMS. Older age and a longer history with pain symptoms were also associated with larger pain extent.

Efficacy of manual lymph drainage and myofascial therapy in patients with fibromyalgia : A systematic review.

INTRODUCTION: Fibromyalgia is a chronic disease of unknown origin characterized by widespread pain, fatigue, disordered sleep and joint stiffness among other symptoms. OBJECTIVE: To compare outcomes of manual lymph drainage and myofascial therapy in patients with fibromyalgia. METHODS: This was a systematic review. The databases PubMed/MEDLINE, CINAHL, SCOPUS, ScieLo, PEDro, Dialnet, Web of Science, and Elsevier were searched for articles in English or Spanish examining the efficacy of myofascial therapy and/or manual lymph drainage to treat fibromyalgia. Of 356 articles extracted, sixteen articles and one doctoral thesis fulfilled the criteria established for inclusion. RESULTS: The methodological quality of the studies reported in the articles was good (PEDro score 7.49 ± 1.47). The studies included compared different treatments with lymph drainage and/or myofascial therapy. Outcomes indicated improved quality of life for both therapies in all the studies. CONCLUSIONS: Myofascial therapy and lymph drainage may be effective in patients with fibromyalgia. Further work is needed as the scientific evidence available is still insufficient.
