This study aims to evaluate the effectiveness of relaxation and breathing training delivered by a physiotherapist and by an artificial intelligence-assisted system in postmenopausal women with non-specific chronic musculoskeletal pain. Menopause and the postmenopausal period are associated with decreased estrogen levels, structural and functional changes in the musculoskeletal system, increased pain prevalence, reduced muscle function, and impaired quality of life. Relaxation techniques, breathing-focused exercises, and mind-body practices have been shown to reduce pain, improve psychological well-being, and enhance sleep quality. With the growing use of digital health technologies, AI-supported relaxation training may offer personalized guidance, easy accessibility, and sustainable home-based practice, although its effectiveness in postmenopausal women has not yet been demonstrated.

In this three-arm randomized controlled trial, participants will be assigned to physiotherapist-led relaxation and breathing training, AI-assisted relaxation and breathing training, or a control group. Interventions will last eight weeks and include sessions three days per week, each approximately 30 minutes. The physiotherapist-guided group will perform sessions face-to-face, while the AI-assisted group will complete prerecorded relaxation and breathing exercises created with AI-generated scripts and voice recordings. The control group will continue daily routines without structured training during the study period.

Assessments will be conducted at baseline and at the end of eight weeks. Outcome measures will include pain severity, pressure pain threshold, musculoskeletal symptoms, menopause-specific quality of life, psychological status, sleep quality, dyspnea, and participant satisfaction. The study aims to compare the effects of physiotherapist-led and AI-assisted training modalities on pain, musculoskeletal health, sleep, psychological well-being, and quality of life. Findings are expected to contribute to the development of accessible and cost-effective interventions that support symptom management and improve the daily functioning of postmenopausal women.

Menopause is a natural biological process defined by the 12 months following a woman's last menstrual cycle. It typically occurs between the ages of 40 and 50, with an average age of onset of around 51. The menopause process is divided into three main phases: perimenopause, menopause, and postmenopause. Perimenopause encompasses the few years preceding menopause, when menstrual cycles become irregular and vasomotor symptoms such as hot flashes and night sweats first appear. The menopausal period is defined as the absence of menstrual bleeding for 12 consecutive months, during which time typical menopausal symptoms become apparent. Postmenopause is the period that lasts for the remainder of a woman's life after menopause. During postmenopause, the decline in estrogen levels causes structural and functional changes in the musculoskeletal system, negatively affecting the integrity of bones, muscles, tendons, and ligaments. The risk of developing sarcopenia and osteoporosis increases during this period. Estrogen contributes to energy metabolism by regulating mitochondrial function in muscle cells; estrogen deficiency results in a decrease in mitochondrial numbers and impaired muscle metabolism. Furthermore, decreased estrogen can increase apoptosis in skeletal muscle, disrupt muscle protein balance, and negatively affect muscle strength. During this period, the prevalence of musculoskeletal pain increases with age, from premenopause to perimenopause and postmenopause. The prevalence of musculoskeletal pain in perimenopausal women has been reported to be approximately 71%; it has also been found that postmenopausal women have a significantly increased risk of experiencing moderate to severe pain compared to premenopausal women. In the literature, methods such as progressive muscle relaxation, breathing-focused awareness exercises and meditation-based relaxation techniques have been shown to reduce pain severity, reduce stress levels and improve quality of life in individuals experiencing chronic pain. These techniques facilitate control of pain perception by reducing muscle tension, improving breathing patterns, and balancing autonomic nervous system responses. For chronic musculoskeletal pain seen in menopausal and postmenopausal women, relaxation training stands out as an effective complementary physiotherapy-based method and significantly contributes to maintaining women's quality of life. Furthermore, chronic pain and menopausal symptoms are closely related to sleep disorders. Studies have shown that relaxation techniques and body-mind-based practices improve sleep quality. It has been reported that relaxation techniques can have positive effects not only on psychological well-being but also on musculoskeletal health. In particular, they have been reported to increase ease of movement and contribute to functional capacity by reducing muscle tension. While the effectiveness of traditional relaxation methods is well known, it is also thought that digital health technologies developed in recent years may offer new opportunities for physiotherapy practices. It has been reported that AI-based systems can be integrated into relaxation and mindfulness applications, providing personalized feedback to guide exercises and enabling sustainable practice in the home environment. Web-based interventions have been found effective in improving the health and quality of life of individuals across various diseases, health behaviors, and psychological conditions due to their advantages such as easy access, low cost, and anonymity. However, despite these strengths, the current status of AI-supported interventions, particularly those related to menopause, remains unclear. However, AI technologies hold the potential to provide personalized care, symptom prediction, and digital support in the management of menopausal symptoms. Furthermore, the effectiveness of AI-based relaxation training applications has not yet been demonstrated. There is a need for long-term, sustainable approaches to the management of chronic pain during menopause and postmenopause that will enhance the potential health benefits. In this context, our study aims to contribute to the literature and clinical practice by comparing the effectiveness of physiotherapist-assisted and AI-assisted relaxation training in postmenopausal women.
