Brief Summary

In recent years, due to the popularity of exercise during pregnancy, the American College of Obstetricians and Gynecologists recommends that pregnant women should engage in 150 minutes of moderate-intensity exercise per week, including aerobic exercise or weight training. This can help reduce pregnancy complications (such as preeclampsia, gestational diabetes, pelvic pain, etc.) and does not increase the risk of miscarriage or premature birth. Pelvic pain during pregnancy is the most troublesome problem for pregnant women, often affecting their daily lives and mental health, leading to the need for long-term use of painkillers and even affecting their daily routine and sleep. Currently, research has also found that exercise during pregnancy can improve pelvic pain during pregnancy and reduce the inconvenience caused by pain in daily life. However, weight training can strengthen spinal stability and reduce lower back pain problems in non-pregnant individuals, but there is currently no research discussing whether weight training for pregnant women can improve pelvic pain during pregnancy, possibly because weight training for pregnant women is not widely accepted by society and is often associated with misconceptions and prejudices. Recent literature synthesis analysis tells us that weight training during pregnancy does not increase the risk of premature birth or miscarriage. Pregnant women in supervised moderate-intensity weight training do not endanger the health of the mother or fetus, and the safety is sufficient. Therefore, we hope to understand the effects and mechanisms of weight training during pregnancy on pelvic pain during pregnancy through this study.

Outcome Measures

Primary Outcomes (1)

• PGQ score

  The main evaluation indicators will include the PGQ activity assessment to evaluate the impact of pelvic girdle pain on daily life, and the PGQ symptom assessment to evaluate the severity of symptoms. These indicators will be used to assess whether weight training during pregnancy improves pelvic girdle pain.

  change of the PGQ score between the first trimester (before GA 14 weeks) and the third trimester before delivery (GA 35 to 36+6 weeks)

Secondary Outcomes (3)

• Cervical length

  difference of the cervical length between the first trimester (before GA 14 weeks) and the third trimester (GA 35 to 36+6 weeks) of the pregnancy

• Duration of the first stage of labor

  During labor

• Duration of the second stage of labor

  During labor

Study Arms (2)

intervention group

EXPERIMENTAL

receive weight training during 16-36 gestational weeks and observe pain condition

Behavioral: weight training

control group

NO INTERVENTION

observe pain condition

Interventions

weight training BEHAVIORAL

Pregnant women assigned to the intervention group will receive online weight training sessions twice a week, for 60 minutes per session, from the 16th to the 36th week of pregnancy. The Pelvic Girdle Questionnaire will be used to assess the condition of pelvic girdle pain during pregnancy, and to analyze whether weight training can improve this problem. Pelvic floor muscle structure will also be analyzed by pelvic ultrasound to determine whether it has been altered by weight training, leading to an improvement in pain.

Eligibility Criteria

• Age: 20 Years - 50 Years
• Gender Eligibility Details: pregnant women
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Pregnant women who are within 14 weeks of gestation and carrying a single fetus.
• Pregnant women who can clearly identify the location of their pelvic girdle pain (e.g. sacroiliac joint or pubic symphysis pain).
• Pregnant women who have at least one positive result in a front pelvic girdle pain test or two positive results in a back pelvic girdle pain test based on the "Self-Administered Pelvic Girdle Pain Test".
• Pregnant women assigned to the intervention group must be able to comply with the exercise program.
• Pregnant women assigned to the control group must not engage in weight training.
• Definition of weight training: The use of resistance to induce muscular contraction, with the goal of increasing strength and endurance of the muscles. This can be achieved systematically using weights, such as one's own body weight, or equipment that provides resistance to muscle contraction, such as dumbbells, barbells, or resistance bands.
• \- Participants will receive follow-up care and delivery at National Taiwan University Hospital in Hsinchu.

You may not qualify if:

• For pregnant women with twins or multiple pregnancies
• With any pregnancy exercise contraindications from the American College of Obstetricians and Gynecologists, including:
• Pre-existing internal medical conditions such as severe unstable heart disease, restrictive lung disease, symptomatic severe anemia, poorly controlled hypertension, poorly controlled diabetes, poorly controlled thyroid disease, and other similar conditions.
• Pregnancy-related conditions such as early rupture of membranes, signs of preterm labor, incomplete cervix closure, history of cervical cerclage, habitual miscarriage, and previous history of preterm birth.
• History of spinal or pelvic surgery
• Known pelvic pain before pregnancy, such as lumbar or pelvic fractures or chronic pain caused by previous surgery
• Clear diagnosis of pre-pregnancy back pain causes, such as herniated discs or nerve root diseases
• Regular use of pain relief medications before pregnancy, such as acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), morphine, and platelet-rich plasma (PRP) therapy
• Regular weight training habit before enrollment (at least twice a week)
• Not planning to give birth at National Taiwan University Hospital
• Already participating in other interventional clinical trials.
