This paper follows the aim to provide a scientifically proved basis for physiotherapists, to ensure that treatment and consulting of patients with endometriosis is based on the newest findings. Thus, the best possible therapy outcome should get achieved.

To clarify how physiotherapy can influence pain and dysfunction of endometriosis patients extensive research of literature was done on several databases. Study selection, quality assessment and data extraction were carried out by the author. The given findings were exemplified in this paper. Afterwards three experts of endometriosis therapy were interviewed to gain their recommendations and perceptions for this paper. As experts identified were physiotherapists working in the gynaecological sector for five or more years, having treated ten or more women with endometriosis. The evaluation of the gathered data was conducted through qualitative content analysis by the author. Eventually a comparison between expert opinion and literature was drawn. Ethical approval or external funding was not required for this study and therefore none is given.

Through the literature research several approaches for physical therapy on endometriosis patients were generated. Nine studies, seven systematic reviews, one case report and one randomized controlled trial (RCT), were included in the paper. The interventions analysed were manual physiotherapy at the pelvic floor and adjacent areas, exercise, relaxation and mindfulness training and high intensity focused ultrasound. The studies investigating manual therapy, relaxation and mindfulness training and high intensity focused ultrasound all showed statistically significant improvements in pain levels or quality of life (QoL). The studies examining exercise therapy showed conflicting results. One study showed statistically significant improvements in pain levels, the two others did not. Due to heterogeneity of patient numbers, form and duration of exercise and study design a comparison could not be drawn. 
As second part of this paper, expert interviews were held with three physiotherapists working in the gynaecological sector and specifically with endometriosis patients. After conducting a qualitative content analysis seven therapy approaches for patients with endometriosis were identified. These include intern pelvic floor palpation, visceral techniques, manual techniques for pain and mobility, awareness training, respiratory therapy, techniques for the central nervous system and exercise therapy. All experts confirmed a high efficacy of physiotherapy for endometriosis symptoms, however there are limitations, such as localisation of endometriotic tissue, pain perception and surgical interventions.

This paper presents a beneficial effect of physiotherapy for symptoms of endometriosis. Both literature and experts suggest that physiotherapy can statistically improve pain levels and QoL. However further research is necessary in order to scientifically prove the potential of physiotherapy regarding endometriosis.

Several therapy strategies on behalf of physiotherapy could lessen pain levels and improve QoL in patients with endometriosis. As yet there is insufficient and conflicting data regarding the therapy on behalf of physiotherapy. This should encourage investigators to design further studies addressing this thematic.
