Postpartum Exercise Intervention

21 maggio 2026 aggiornato da: 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.

Descrizione dettagliata

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).

Sperimentale: Exercise Intervention
Study participants will attend a 1-hour in-person group exercise intervention once a week for 8 weeks.
Test diagnostico: Test attivo di sollevamento della gamba dritta
Il test ASLR è un test clinico consolidato che valuta la stabilità della colonna lombare/bacino, la gravità del dolore pelvico posteriore e la capacità di attivare i muscoli addominali. Si esegue in posizione supina. Ai partecipanti viene chiesto di sollevare una gamba, con il ginocchio dritto, a un'altezza del tallone di 20 cm. La gamba viene tenuta in alto per 5 secondi, quindi abbassata lentamente a terra. Al partecipante viene chiesto di riportare la difficoltà percepita a sollevare la gamba su una scala da 0 a 5 (0=per niente difficile; 5=impossibilità di sollevare la gamba) e il dolore su una scala da 0 a 10 (0=nessun dolore; 10=peggiore possibile dolore). Se la difficoltà o il dolore sono valutati a 1 o superiore, il test viene ripetuto con il ricercatore che fornisce compressione esterna del bacino. Se la difficoltà percepita o il dolore riferito sono inferiori con la compressione, il test è considerato positivo per l'instabilità lombopelvica. Il test viene quindi ripetuto sull'arto opposto.
Altri nomi:
  • Prova ASLR
Altro: Attività di sollevamento della fatica con gamba dritta attiva
Il protocollo è simile al test ASLR, tranne per il fatto che al partecipante viene chiesto di mantenere la gamba sollevata da terra il più a lungo possibile. Un bracciale ad aria per biofeedback verrà posizionato sotto la regione lombopelvica del partecipante per valutare il movimento della colonna vertebrale/bacino. Il bracciale verrà gonfiato a 40 mm Hg e il partecipante verrà incaricato di mantenere l'ago il più vicino possibile a 40 mm Hg durante il test; non verranno fornite informazioni su come influenzare la pressione del bracciale, ma durante l'attività verrà fornito un feedback visivo della pressione del bracciale. Le valutazioni dello sforzo percepito (RPE) e del dolore saranno ottenute dai partecipanti ogni 30-60 secondi. Il fallimento del compito sarà definito come un'altezza del tallone ≤10 cm o un cambiamento nella pressione del bracciale ≥20 mm Hg. Verranno testati entrambi gli arti, ma in sessioni diverse. L'ordine dei test sugli arti (dominante vs non dominante) sarà randomizzato e controbilanciato. La dominanza degli arti sarà auto-riportata.
Test diagnostico: Ecografia della parete addominale
Verranno utilizzati ultrasuoni in tempo reale per valutare la distanza inter-retta sopra e sotto l'ombelico. I partecipanti saranno valutati con immagini in modalità B in posizione supina a riposo, in posizione supina mentre si solleva la testa e in posizione supina durante l'esecuzione di un sollevamento della gamba tesa. Il Principal Investigator ha formazione ed esperienza nell'ecografia muscoloscheletrica.
Altro: Progressive exercise
A progressive, 8-week exercise intervention has been developed and will be administered in a group setting.

  • Esercizio
Altro: 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.
Altro: 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).
Altro: 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.
Comparatore attivo: Control
Study participants will not receive the exercise intervention but will complete a weekly questionnaire to self-report physical activity levels.

Physical activity levels via self-reported questionnaires
Lasso di tempo: Once-a-week for the 8-week intervention period
Participants will complete the International Physical Activity Questionnaire (IPAQ) short-form. The IPAQ short-form quantifies physical activity (PA) over the previous week in 2 categories: low, moderate, or high activity; or metabolic equivalents (MET) minutes per week. High PA is categorized as (1)vigorous PA on at least 3 days/week with a combined minimum of at least 1500 MET minutes/week or (2) 7 days of cumulative PA of any intensity that sums to a minimum total of at least 3000 MET minutes/week. Moderate PA is categorized as (1) 3+ days of at least 30 minutes of vigorous PA, (2) 5+ days of moderate PA or walking at least 30 minutes/day, or (3) 5+ days of any level of PA that sums to a minimum of 600 MET minutes/week. Low physical activity is categorized as activity that does not meet the criteria for medium or high activity.
Once-a-week for the 8-week intervention period
Lower extremity strength
Lasso di tempo: Baseline and 7-14 days post-intervention
A straight leg raise maximal voluntary contraction (MVC) of each lower extremity will be performed in supine before and within 2 minutes of completing the ASLR fatigue task with a custom made load cell instrumented strength testing device. This device consists of a rigid platform on which the study participant will lie supine. At the foot of the device is a tower that houses 2 load cells and is connected to a lightly padded push plate. This push plate can be raised and lowered such that the participant can push up into the plate (contacts the anterior surface of the participant's shin) or push down onto the push plate (contacts the posterior aspect of the participant's heel). Before the ASLR fatigue task, a minimum of 3 MVC trials will be performed on each leg, with a minimum of 1 minute rest between trials; the highest peak force will be considered the MVC. Only 1 MVC trial per leg will be performed following the fatigue task.
Baseline and 7-14 days post-intervention
Mean Time to ASLR Fatigue Task Failure
Lasso di tempo: Baseline and 7-14 days post-intervention
The Active Straight Leg Raise Fatigue Task will be administered. Participants are asked to raise one leg to a heel height of 20 cm while lying supine. Participants are encouraged to keep the leg raised as long as possible. Task failure will be defined as a heel height less than or equal to 10 centimeters off the ground.
Baseline and 7-14 days post-intervention
Pelvic floor muscle strength
Lasso di tempo: Baseline and 7-14 days post-intervention
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) with 5 being the strongest.
Baseline and 7-14 days post-intervention
Pelvic floor muscle endurance

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.55 The time in seconds is recorded.
Baseline and 7-14 days post-intervention
Mean Pelvic Floor Distress Inventory Short Form (PFDI-20) Score
Lasso di tempo: Baseline and 7-14 days post-intervention
The PFDI-20 is composed of 20 items total on three scales (Pelvic Organ Prolapse, Colorectal-Anal Distress, Urinary Distress), each scored on a 5 point likert scale. Mean scores from each scale are calculated and multiplied by 25, then added together for a total possible range of scores from 0-300. Higher scores indicate increased pelvic floor distress.
Baseline and 7-14 days post-intervention
Fear of movement
Lasso di tempo: Baseline and 7-14 days post-intervention
Fear of movement (kinesiophobia) will be assessed via the Tampa Scale for Kinesiophobia (TSK). The TSK is a 17-question, self-administered questionnaire that utilizes a 4-point Likert scale (1= strongly agree, 4=strongly disagree). Total scores range from 17-68. A higher score indicates higher levels of kinesiophobia; a score of 17 indicates no/minimal kinesiophobia.
Baseline and 7-14 days post-intervention
Overall quality of life
Lasso di tempo: Baseline and 7-14 days post-intervention
Participants will complete the SF-20 questionnaire, which measures health in six different domains (physical functioning, role functioning, social functioning, mental health, health perceptions, and pain). Scores range from 0-100%, with 0% being the worst score and 100% being the best.
Baseline and 7-14 days post-intervention
Mean Global Pittsburgh Sleep Quality Index (PSQI) Score
Lasso di tempo: Baseline and 7-14 days post-intervention
The PSQI assesses seven sleep domains: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. The seven components scores are then added to yield a global PSQI score in the range of zero to 21. Higher scores indicate worse sleep quality. A global score greater than five is diagnostic of poor sleep quality.
Baseline and 7-14 days post-intervention
Inter-recti distance
Lasso di tempo: Baseline and 7-14 days post-intervention
Ultrasound imaging will be used to measure the distance between the right and left rectus abdominis at 2 locations above the umbilicus and 2 locations below the umbilicus. IRD will be assessed in supine at rest (end exhalation), while lifting the head, and while lifting one leg.
