[en] Introduction. Primary dysmenorrhea is the most common pathology suffered by women which are in their reproductive years. Its symptoms are mainly manifested in the lower abdominal area, and on many occasions with irradiation to the lower back and / or thighs. Primary dysmenorrhea is characterized by its first appearance within the first two years after menarche as well as the absence of underlying pelvic pathology, unlike the secondary one, associated with pelvic pathology. Objective. The main objective of this research project is to analyze whether the physiotherapy multimodal treatment based on: therapeutic exercise, TENS and thermotherapy is effective in the treatment of primary dysmenorrhea. Methodology. We are going to conduct a prospective, parallel, longitudinal randomized clinical trial. The intervention will be carried out with 66 patients from the Faculty of Physiotherapy of the University of A Coruña divided into three groups (22 subjects in each of the two experimental groups and 22 subjects in the control group). As for the first experimental group, they will receive a physiotherapy treatment based on therapeutic exercise, TENS and thermotherapy, while the second will receive the same intervention together with NSAIDs. Finally, the control group will receive treatment with NSAIDs. The intervention will last 4 menstrual cycles, therefore 16 weeks. The treatment of the experimental group will be divided into; during the days of the menstrual period, TENS and thermotherapy, while the rest of the days of the month the therapeutic exercise will be carried out, 3 days per week. Applicability. If the alternative hypothesis is confirmed, the combination of TENS, thermotherapy and therapeutic exercise will reduce the patients' painful symptoms, and as a consequence, an improvement in their quality of life will be achieved. In this way, this combination of treatments would represent an advance in the physiotherapeutic approach to dysmenorrhea.

[gl] Introdución. A dismenorrea primaria é a patoloxía máis frecuente da muller en idade fértil. A súa sintomatoloxía manifestase principalmente na zona baixa do abdome, e en moitas ocasións irradia cara á rexión lumbar e/ou muslos. A dismenorrea primaria caracterízase por presentar a súa primeira aparición nos dous primeiros anos tras a menarquía así como pola ausencia de patoloxía pelviana subxacente. Obxectivo. O principal obxectivo de este proxecto é analizar se o tratamento multimodal de fisioterapia baseado en; exercicio terapéutico, TENS e termoterapia é efectivo no tratamento da dismenorrea primaria. Metodoloxía. Levaremos a cabo un ensaio clínico aleatorizado, paralelo, lonxitudinal e prospectivo. A intervención levarase a cabo con 66 pacientes da Facultade de Fisioterapia da Universidade Da Coruña, divididas en 3 grupos (22 suxeitos en cada un dos dous grupos experimentais e 22 no grupo control) En relación ós grupos experimentais, o primeiro recibirá un tratamento de fisioterapia baseado en exercicio terapéutico, TENS e termoterapia, mentres que o segundo recibirá a mesma intervención xunto con AINEs. Por último, o grupo control recibirá tratamento só con AINEs. O tratamento do grupo experimental dividirase en; durante os días do período menstrual, TENS e termoterapia, mentres que o resto dos días do mes realizarase exercicio terapéutico, 3 días por semana. Aplicabilidade. No caso de confirmarse a hipótese alternativa, a combinación do TENS, a termoterapia máis o exercicio terapéutico conseguirá diminuír a sintomatoloxía das pacientes, e como consecuencia conseguirase una melloría na calidade de vida das mesmas. De este xeito, dita combinación de tratamentos suporía un avance na abordaxe fisioterapéutico da dismenorrea.
