Postpartum Exercise Intervention

2026년 5월 21일 업데이트: Rita Deering, Carroll University

Influence of a Supervised Postpartum Exercise Program on Maternal Physical Activity Levels and Musculoskeletal Health

The postpartum period is associated with decreases in physical activity levels, muscular strength, muscular endurance, and pelvic floor muscle function, but little scientific evidence exists on how best to initiate and progress exercise in the postpartum period. This proposal aims to improve habitual physical activity levels, neuromuscular health (i.e., strength, fatigability, symptom burden) and overall wellbeing (i.e., decreased fear of movement, improved sleep quality, improved perception of quality of life) through participation in a weekly exercise program. This study will help to inform postpartum exercise recommendations and is novel as it allows participants to incorporate their children into the exercise routine, thus removing a primary barrier to physical activity/exercise.

상세 설명

Physical activity (PA)/exercise is crucial for maternal health and wellbeing but several barriers to PA/exercise participation exist in the postpartum period. Musculoskeletal impairments-such as weakness, increased fatigability, pelvic floor dysfunction (e.g., incontinence, pelvic organ prolapse, etc.), and pain-are common in the postpartum period. While these impairments provide strong rationale for participation in PA/exercise, they can also act as barriers to participation. Several psychosocial barriers also exist, including fear of movement and lack of childcare. Despite the importance of PA/exercise for health and wellness, and the documented musculoskeletal impairments that are associated with the postpartum period, assessment of neuromuscular function and education on resuming exercise is lacking in the standard postpartum care model in the United States. In addition, conflicting information can be found on social media and among clinical experts on when and how to best resume PA/exercise after childbirth. This proposal will evaluate the influence of an eight-week exercise intervention on neuromuscular function (i.e., lower extremity strength & endurance, pelvic floor muscle strength & endurance, self-reported pelvic floor dysfunction symptoms), habitual physical activity levels, and overall wellbeing (i.e., levels of kinesiophobia, sleep quality, self-reported quality of life) in postpartum females. In an effort to decrease barriers to exercise, childcare will be offered, and participants will have the opportunity to incorporate their child(ren) into exercise sessions if they so desire. This proposal will utilize a randomized control trial (RCT) design and objective measures of strength (i.e., load cells) along with standard clinical assessments of pelvic floor muscle function (i.e., internal vaginal assessment of strength and endurance, self-reported symptoms using validated questionnaires).

다른: Lower Extremity Strength Testing
A straight leg raise maximal voluntary contraction (MVC) of each lower extremity an MVC of the hip extensors of the grounded limb will be performed in supine before and within 2 minutes of completing the ASLR fatigue task. The straight leg raise MVC will be performed with a custom-made load cell instrumented strength testing device, which consists of a rigid platform on which the participant will lie. At the foot of the device is a tower that houses 2 load cells connected to a lightly padded push plate. The hip extension MVC will be performed on a force plate. Before the ASLR fatigue task, a minimum of 3 MVC trials will be performed for each muscle group, with a minimum of 1 minute rest between trials; the highest peak force will be considered the MVC. Only 1 MVC trial per muscle group will be performed following the ASLR Fatigue Task.
다른: Pelvic Floor Muscle Strength Testing
An internal vaginal pelvic floor muscle assessment will be performed at baseline and study completion by a licensed physical therapist with advanced training in pelvic floor muscle examination and treatment. Pelvic floor muscle function will be assessed using the PERFECT scale, which assesses both muscular strength ("P" for "power") and endurance ("E"). Strength is assessed by cueing the participant to perform a maximal voluntary pelvic floor muscle contraction while the examiner has their index finger inserted into the vagina. The modified Oxford scale is used to grade strength on a scale of zero (0) to five (5).
다른: Pelvic Floor Muscle Endurance Testing
Pelvic floor muscle endurance is also assessed via the internal vaginal PFM examination. After strength testing is performed, participants are instructed to perform a maximal PFM contraction and hold for as long as possible (maximum of 10 seconds). The examiner counts the length of the contraction, and timing is stopped either when (1) strength of the contraction declines or (2) the maximum of 10 seconds is reached. The time in seconds is recorded.
