Brief Summary

This study aims to investigate the effect of primary dysmenorrhea on the activity of the abdominal and back muscles in young adult females.

Conditions

Primary Dysmenorrhea

Keywords

Muscle Activity; Maximum Voluntary Contraction; EMG; Primary Dysmenorrhea

Outcome Measures

Primary Outcomes (2)

• Activity of rectus abdominis muscle

  Maximum voluntary contraction in (μV) of rectus abdominis using electromyography device (EMG)

  3 months

• Activity of erector spinae muscle at L3 vertebrae Level

  Maximum voluntary contraction in (μV) of erector spinae at L3 Level using electromyography device (EMG)

  3 Month

Study Arms (3)

Group A: Mild dysmenorrhea

Females with mild PD, scoring (1-4) on the WaLLID scale.

Diagnostic Test: Record EMG maximum amplitude from rectus abdominis, erector spinae L3 level

Group B: Moderate dysmenorrhea

Females with moderate PD, scoring (5-7) on the WaLLID scale.

Diagnostic Test: Record EMG maximum amplitude from rectus abdominis, erector spinae L3 level

Group C: Severe dysmenorhhea

Females with severe PD, scoring (8-12) on the WaLLID scale.

Diagnostic Test: Record EMG maximum amplitude from rectus abdominis, erector spinae L3 level

Interventions

Record EMG maximum amplitude from rectus abdominis, erector spinae L3 level DIAGNOSTIC_TEST

EMG Electrode Placement and Muscle Assessment: Electrodes for the rectus abdominis were placed longitudinally at the umbilical level. For the erector spinae, L3 was located using a line between the posterior superior iliac crests, and electrodes were placed \~3 cm lateral to the L3 spinous process. Assessment: Rectus Abdominis: In the crook-lying position, participants performed a slow curl-up (\~35-40°), holding for 10 seconds. Erector Spinae: In the prone position with a 10-cm pad under the abdomen, participants lifted the upper body with neutral cervical alignment for 10 seconds. Each test was repeated three times with 2-minute rest intervals.

Group A: Mild dysmenorrhea; Group B: Moderate dysmenorrhea; Group C: Severe dysmenorhhea
