Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pregnant women at increased risk for back pain were studied during the second trimester and randomized to12-weeks of resistance exercise, education or waitlist. Several outcomes were assessed including physical function, quality of life and mood.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A parallel group trial was completed at a single site. Second trimester women (n=134) were randomly assigned (in blocks of 3) to 12-weeks of wait list, bi-monthly pregnancy education classes or twice weekly low-to-moderate intensity resistance training. Resistance training involved one abdominal exercise with no external load and five exercises with an external load that gradually progressed (leg extension, leg press, arm lat pull, leg curl, and lumbar extension). Several outcomes were assessed including physical function, quality of life and mood.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Resistance exercise

Resistance exercise involved 12 weeks of weight lifting exercise

Group Type EXPERIMENTAL

Resistance exercise

Intervention Type BEHAVIORAL

Resistance exercise involved 12-weeks of strength training twice per week

Wait list

Wait list participants were tested on the outcomes during their pregnancy and were eligible to participate in a post-partum supervised exercise program. The wait list participants formed a no treatment control group.

Group Type SHAM_COMPARATOR

Wait list

Intervention Type OTHER

Wait list participants were tested on the outcomes during their pregnancy and were eligible to participate in a post-partum supervised exercise program. The wait list participants formed a no treatment control group.

Pregnancy education

Maternity nurses taught six bimonthly pregnancy education classes (\~20 per class) which covered several topics including information about what to expect during normal labor and delivery, common interventions during delivery (medications, induction, Cesarean delivery), parenting skills needed for baby care, breastfeeding, baby and child cardiopulmonary resuscitation, typical child development and communicating with infants. No physical activity education was included in the curriculum. The pregnancy education participants formed an attention control group.
