It will consist of 20 participants with primary dysmenorrhea. They will receive progressive relaxation techniques three times per week, for 30 minutes once daily and will follow lifestyle modification advices for 3 consecutive menstrual cycles for 12 weeks.

It will consist of 20 participants with primary dysmenorrhea. They will perform isometric exercises 5 days a week, two sessions a day, for 10 times per session and also followed lifestyle modification for 3 consecutive menstrual cycles for 12 weeks.

Progressive relaxation exercises will be performed using controlled breathing combined with sequential muscle contraction and relaxation. Participants will be instructed to contract specific muscle groups during inspiration for 5-7 seconds, followed by relaxation during expiration for 15-20 seconds while focusing on the sensation of release. The sequence will include movements of the toes (flexion/extension, abduction/adduction), subtalar inversion/eversion, ankle dorsiflexion/plantarflexion, finger flexion/extension and abduction/adduction, as well as wrist flexion/extension and radial/ulnar deviation. This protocol will be carried out in a structured manner for approximately 25 minutes.

Pain intensity will be assessed for all participants in the three groups before and after the intervention using the Visual Analog Scale (VAS). The VAS is a one-dimensional measure consisting of a 10 cm horizontal line representing a continuum from "no pain" to "worst imaginable pain." Participants will be instructed to mark a point on the line that best reflects their current pain intensity, and the score will be determined by measuring the distance from the "no pain" end.

The Menstrual Distress Questionnaire (MDQ) will be used to assess symptom severity in all groups (A, B, and C) before and after treatment. Participants will rate their experience of each symptom on a scale ranging from no symptoms to severe or partially disabling symptoms. The MDQ consists of eight subscales: pain, impaired concentration, behavioral change, autonomic reactions, water retention, negative affect, arousal, and control. Symptoms are typically rated on a 4-point scale (0 = no symptoms to 3 = severe symptoms) or, in some versions, a 6-point scale. Subscale scores will be calculated by summing item ratings within each category, with higher scores indicating greater menstrual distress.

The Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) will be used to assess overall life satisfaction across multiple domains, including physical health, mood, work, daily activities, social relationships, economic status, and overall well-being. It is a validated self-reported measure of enjoyment and satisfaction in daily life. Participants will rate each item on a 5-point scale ranging from "very poor" to "very good." Total scores will be calculated as a percentage of the maximum possible score, with higher scores indicating better quality of life. A score above 70% will be considered indicative of normal quality of life.
