Brief Summary

this study will be conducted to Investigate the relationship between primary dysmenorrhea and biomechanical characteristics of lumbo-pelvic region among female university students

Conditions

Dysmenorrhea Primary

Keywords

Primary Dysmenorrhea; Biomechanical Characteristics; Lumbo-pelvic Region; Female University Students

Outcome Measures

Primary Outcomes (1)

• life disability

  The WaLIDD score (Working ability, Location, Intensity, and Days of pain) is a clinical questionnaire used to evaluate the severity of dysmenorrhea (painful menstruation) and to predict the likelihood of a person needing medical leave. It evaluates the condition using four criteria, each scored from 0 to 3, yielding a total possible score ranging from 0 to 12 points.Low/Mild Score (0 to 4 points): Indicates no dysmenorrhea.Moderate Score (5 to 7 points): Indicates moderate dysmenorrhea.High Score (8 to 12 points): Indicates severe dysmenorrhea.

  up to one day

Secondary Outcomes (8)

• pain intensity

  up to one day

• pelvic tilt angle

  up to one day

• muscle activity

  up to one day

• oscillatory frequency

  up to one day

• muscle dynamic stiffness

  up to one day
