Evaluation of sexual dysfunction in females with neck and upper back myofascial pain syndrome: a cross-sectional study.

Myofascial pain syndrome (MPS) is a prevalent chronic musculoskeletal pain disorder that is frequently encountered in clinical practice and can cause sexual dysfunction in women. While there have been studies examining sexual function in various painful rheumatic conditions, particularly fibromyalgia, no studies have been conducted specifically on primary MPS. In this context, we aimed to investigate the frequency of sexual intercourse and the factors associated with it in women diagnosed with MPS. The study was designed as a cross-sectional study at a tertiary rehabilitation center between May 2022 and April 2023. Forty-five consecutive sexually active women (mean age: 38.1 ± 6.8 years) diagnosed with primary MPS were included in the study. They were compared to 45 healthy women of similar ages. The participants were interviewed regarding their weekly frequency of sexual intercourse and the importance of sexual life. Also, the Beck Depression Inventory (BDI) and the Visual Analog Scale (VAS) were assessed. The importance of sexual life score (p = 0.008), BDI (p < 0.001), VAS pain (p < 0.001), and VAS fatigue (p < 0.001) values were found to be lower in the patient group compared to the control group. The frequency of sexual intercourse was lower in the patient group, although this difference did not reach statistical significance (p = 0.083). In patients with a higher BDI score (≥ 17), the number of sexual intercourse was lower (p = 0.044), and the severity of fatigue was higher (p = 0.013). Significant associations were observed in MPS patients between the weekly frequency of sexual intercourse and VAS pain, VAS fatigue, BDI, and the importance of the sexual life score. A positive correlation was observed between the number of weekly sexual intercourses and the importance of the sexual life score (r = 0.577, p < 0.001), and negative correlations were found between BDI (r = - 0.478, p < 0.001), VAS pain (r = - 0.409, p < 0.001), and VAS fatigue (r = - 0.439, p < 0.001). Patients with MPS should be assessed for depressive mood and fatigue, as these factors may contribute to sexual dysfunction. These results may also emphasize the importance of adopting a multidisciplinary approach in the management of MPS patients with concurrent sexual dysfunction.
