Premenstrual Syndrome (PMS) is a multifactorial disorder affecting women of reproductive age, causing physical discomfort, emotional instability, and reduced quality of life. This randomized clinical trial aims to compare the effects of Somatic Movement Therapy (SMT) and Core Strengthening Exercises (CSE) on symptom severity, perceived stress, and quality of life in 34 female participants aged 18-35 years diagnosed with PMS according to ACOG criteria. Group A will receive SMT, while Group B will perform CSE over a 6-week program. Outcomes will be measured using PSST, PSS-10, and WHOQOL-BREF, with data analyzed through SPSS version 27.
Premenstrual Syndrome (PMS) is a complex and multifactorial disorder affecting a significant proportion of women of reproductive age, often resulting in substantial physical discomfort, emotional instability, and reduced quality of life. Recent studies have confirmed the use of movement-based therapeutic interventions as effective prescription-free methods to provide relief of the symptoms associated with PMS. The purpose of the study is to examine and compare the effect of intervention (Somatic Movement Therapy (SMT) and Core Strengthening Exercises (CSE) on symptom severity, perceived stress, and quality of life in patients with PMS. This randomized clinical trial will be conducted at Ghurki Trust and Teaching Hospital, involving a sample of 34 female participants aged 18 to 35 years with regular menstrual cycles and a clinical diagnosis of Premenstrual Syndrome according to ACOG (American College of Obstetricians and Gynecologists) criteria. A non-probability convenience sampling method will be used to recruit the participants, and they will be assigned randomly to two intervention groups. Somatic Movement Therapy will be applied in Group A and will include breath awareness, proprioceptive training, somatic movement, and mindfulness-based relaxation. Group B will be subjected to a highly structured Core Strengthening Exercises regime that involves progressive movement on basic activation to endurance-based core exercises in a 6-week regime (3 sessions/week, 45 minutes/session). Outcome measures include the Premenstrual Symptoms Screening Tool (PSST) for symptom severity, the Perceived Stress Scale (PSS-10), and the WHOQOL-BREF for quality of life. Evaluations will be done at baseline, post-intervention, and follow up. SPSS version 27 will be used to analyze data.

Participants allocated to Group A will receive a structured Somatic Movement Therapy (SMT) program specifically designed to manage the physiological and psychological manifestations of premenstrual syndrome (PMS). Each session will begin with a centering and breath awareness phase lasting 5 to 10 minutes, wherein diaphragmatic breathing is emphasized to stimulate the parasympathetic nervous system and reduce sympathetic overdrive commonly observed in PMS. It is followed by 15 to 20 minutes of gentle somatic movements. The session then transitions to a body scan and proprioception segment (5-10 minutes), which includes guided internal sensing of different body parts and their spatial orientation, supported by verbal cues or tactile prompts. The session ends by mindfulness and relaxation period (10-15 minutes) adding guided visualization, body integration or meditative stillness.
Participants in Group B will engage in a progressive Core Strengthening. The sessions will begin with a 5-10-minute warm-up period, which will include low-intensity aerobic activities, dynamic stretching, and simple joint mobilization exercises. The main activation step will take around 25-30 minutes and consist of guided exercises like abdominal bracing exercises, bridges, planks, and bird-dog variations. The progression will be systematic and start with simple exercises of control bases in week 1-2, then add a challenge by adding movements such as side planks, heel slides, and leg raises in week 3-6. As the participants adapt to he regimen, endurance-oriented movements such as bicycle crunches and superman holds will be incorporated during weeks 4-5 to enhance core stability under fatigue. Every session will be concluded by a recovery time (5-10 minutes). It will consist of four 45-minute sessions per week, 3 times per week, and 6 weeks, totaling 18 sessions per subject.

RECRUITINGPerceived Stress Scale (PSS-10)
PSS-10 is a psychological tool, which is a well-established measure of past-month perceptions of stress. It measures the degree to which respondents find their lives to be unpredictable, uncontrollable and overwhelming, and thus is very applicable in assessing the level of stress involved in PMS. It is a 10 item survey that is measured on a 5 point Likert scale and is sensitive to pre and post-intervention changes in stress levels after physical and psychological interventions. The PSS-10 will be useful in this study to assess how the interventions have affected stress perceptions among the participants. Psychometric properties are high, with the Cronbach alpha of 0.78-0.91, which demonstrates a good internal consistency and construct validity of the tool .
Time frame: 6 weeks
Premenstrual Symptoms Screening Tool (PSST)
The PSST is a widely used clinical tool designed to identify and assess the severity of symptoms associated with Premenstrual Syndrome (PMS). It encompasses various physical, emotional, and behavioral symptoms that are normally experienced in the luteal stage of the menstrual cycle. Participants evaluate the severity and effects of irritability, bloating, fatigue, mood swings, and sleeping disturbances. Regarding this study, the PSST will be useful in quantifying the symptom burden pre- and post-intervention to enable a comparative study between somatic movement therapy and core strengthening exercises. The PSST has proven to be of high internal consistency with a Cronbach alpha typically being reported to be greater than 0.9, which verifies the reliability and validity of the PSST in both clinical and research contexts.

WHOQOL-BREF Questionnaire
The WHOQOL-BREF is a standardized tool developed by the World Health Organization to assess quality of life across four domains: physical health, psychological health, social relationships, and environment. The tool is most applicable in measuring global shifts in well-being, which is critical in assessing the overall impact of interventions on women with PMS. WHOQOL-BREF scores can be used to indicate improvement in mood, pain, stress levels, and physical functioning. The instrument has been tested using a wide range of populations and languages and demonstrated to be highly reliable (Cronbach alpha consistently above 0.7 in all domains) and content and construct validity, which makes it a suitable instrument to assess the quality of life in this study.
