Background: There are few studies that objectively assess physical activity using accelerometry in postpartum women and none that do so before 3 months postpartum. It is not known whether accelerometry can be successfully used in the early postpartum period and thus benefit studies designed to assess the health benefits and risks of early physical activity. Wear compliance may be substantially lower several weeks after childbirth, given the overwhelming nature of the early postpartum period, particularly for first time mothers. The aims of this study were to 1) describe the methods used to facilitate protocol compliance of wrist-worn accelerometry, 2) describe device usage and wear time in early postpartum primiparous women and 3) to place the compliance characteristics of early postpartum primiparous women in our study in context with that of other studies of postpartum women and standards published by large, physical activity surveillance studies. Methods: Participants were primiparous women who were enrolled at 3rd trimester in a larger ongoing prospective cohort study, delivered vaginally, and lived in a 60 mile radius of the research site. The parent study was designed to evaluate the effects of early physical activity on pelvic floor health. Participants wore a wrist accelerometer (ActiGraph™ GT3XLink device) over two 7-day periods, 2–3 weeks and 5–6 weeks postpartum. We developed a protocol based on best practices to enhance compliance in this population. The Choi (2011) algorithm was used to determine wear time. Results: Of all participants, 82.6% (166 of 201 eligible) and 70.1% (141 of 201 eligible) at 2–3 and 5–6 weeks, respectively, received and wore a functional device in the correct study time-frame for at least 7 days. Of participants that received a functional device, 94.3% (166/176) and 86.5% (141/163) wore the device for at least 7 days, with mean wear times of 1348.0 (135.8) minutes/day and 1313.5 (152) minutes/day, respectively. At 2–3 weeks, 96.1% and 90.4% met the NHANES and Whitehall II Study wear standards, respectively, while at 5–6 weeks, 93.9% and 84.1% did so. Conclusion: Despite challenges in conducting physical activity research in postpartum women, adherence to wrist-worn accelerometry is high with this protocol.

Objective: Most studies about truncal pain during and after pregnancy focus on low back pain, few prospectively define change in pain, and even fewer evaluate pain in all three major truncal areas: upper back, lower back, and pelvic girdle. Thus, the objective of this prospective cohort study was to describe, in primiparous women delivered vaginally, prevalence rates and severities of upper back, lower back, and pelvic girdle pain during pregnancy and 6–10 weeks postpartum and to describe the trajectory of pain constellations between time points. Study design: Participants completed questionnaires at each time point. Pain intensity was rated on a visual analogue scale ranging from 0 to 100. Results: Of the 288 participants, 94% reported truncal pain during pregnancy, while 75% did so postpartum. Prevalence rates of upper back, lower back, and pelvic girdle pain with or without other types of pain during pregnancy were 42%, 77%, and 74% and postpartum were 43%, 52%, and 41%, respectively. Pain severity was highest for women endorsing pain in three locations (median 55–60). Of women with the most common pain constellation during pregnancy, lower back and pelvic girdle (32%), 18% had persistent low back and pelvic girdle pain postpartum, 20% had no pain, and the remainder had pain in a different location. Of women with pain in all three locations during pregnancy (27%), 34% had persistent pain in three locations postpartum, 13% had no pain, and the remainder had pain in at least one location. Conclusion: More women experience pain in a constellation of locations than in a single location. Severity increases as number of pain sites increase. Women with pain in three sites during pregnancy are least likely to have pain resolve. Interventions should focus on the entire trunk and not simply one site of pain.

Abstract The pelvic organ prolapse quantification system (POP-Q) is currently the most quantitative, site-specific system for describing pelvic organ prolapse. To ensure that anatomic outcomes can be optimally assessed, investigators in the Pelvic Floor Disorders Network evaluated the impact of specific technique variations on POP-Q measurements performed on 133 patients by 16 examiners at seven sites. Values for genital hiatus and perineal body were higher when measured with maximal strain than on resting. With the exception of TVL, internal points did not differ significantly when measured with or without a speculum. The maximum extent of prolapse was best seen with the patient standing. These results suggest that genital hiatus and perineal body should be measured at rest and during straining, as the measurements may assess different aspects of pelvic floor function, and that internal points can be measured with or without a speculum. They also emphasize the value of the standing examination to observe the maximum extent of pelvic organ prolapse. [ABSTRACT FROM AUTHOR]
