Is Pregnancy-Related Lumbopelvic Pain Reported to Health Care Providers?

Background: Pregnancy-related lumbopelvic pain (PLPP) is a common ailment during pregnancy with physical, psychosocial, and economic consequences. Despite being common, prior literature has found that this symptom is widely underreported and therefore undertreated, especially in the United States. The objectives of this study were to determine the proportion of pregnant women who report PLPP during pregnancy to their health care providers (HCPs) and to determine what contributing factors for reporting exist. Materials and Methods: This is a cross-sectional survey design and was conducted at an academic medical center. All pregnant women attending a prenatal visit in obstetrical offices from July 2018 through March 2020 were asked to complete a questionnaire compiling demographic and socioeconomic information, answer validated survey instruments measuring physical and urinary function, and describe any pain, including intensity, frequency, and whether they told their HCPs about these symptoms and received any treatments. Results: Of the 538 respondents who had PLPP, only 43% (n = 233) reported PLPP to their provider. Of those who reported PLPP, 22% (n = 51) received treatment, of which 80% (n = 41) noted that treatment was effective. Factors that increased the likelihood of informing HCPs about PLPP were difficulty with daily mobility and a greater week of gestation. Conclusions: HCPs should inquire about PLPP throughout pregnancy. Any level of PLPP should be reported and monitored by a patient's HCP, and if it is interfering with activities of daily living, sleeping, or quality of life, it should be treated.

Artificial Neural Network-Based Activities Classification, Gait Phase Estimation, and Prediction.

Gait patterns are critical to health monitoring, gait impairment assessment, and wearable device control. Unrhythmic gait pattern detection under community-based conditions is a new frontier in this area. The present paper describes a high-accuracy gait phase estimation and prediction algorithm built on a two-stage artificial neural network. This work targets to develop an algorithm that can estimate and predict the gait cycle in real time using a portable controller with only two IMU sensors (one on each thigh) in the community setting. Our algorithm can detect the gait phase in unrhythmic conditions during walking, stair ascending, and stair descending, and classify these activities with standing. Moreover, our algorithm is able to predict both future intra- and inter-stride gait phases, offering a potential means to improve wearable device controller performance. The proposed data-driven algorithm is based on a dataset consisting of 5 able-bodied subjects and validated on 3 different able-bodied subjects. Under unrhythmic activity situations, validation shows that the algorithm can accurately identify multiple activities with 99.55% accuracy, and estimate ([Formula: see text]: 6.3%) and predict 200-ms-ahead ([Formula: see text]: 8.6%) the gait phase percentage in real time, which are on average 57.7 and 54.0% smaller than the error from the event-based method in the same conditions. This study showcases a solution to estimate and predict gait status for multiple unrhythmic activities, which may be deployed to controllers for wearable robots or health monitoring devices.

Lumbopelvic Pain in Pregnancy in a Diverse Urban Patient Population: Prevalence and Risk Factors.

Objective: Pregnancy lumbopelvic pain (PLPP) is a common ailment during pregnancy with physical, psychosocial, and economic consequences. Prior literature has focused on majority Caucasian patient populations; none have focused on Hispanic populations, especially in the United States. The purpose of this study was to determine the proportion of pregnant people who experience PLPP in mostly Hispanic population. Materials and Methods: Cross-sectional survey Setting: Academic medical center Patients: All pregnant people attending a prenatal visit in obstetrical offices from July 2018 through March 2020 were asked to complete a questionnaire compiling demographic, socioeconomic information as well as describe any pain symptoms. Furthermore, the Pregnancy Mobility Index (PMI), Pelvic Girdle Pain Questionnaire (PGQ), and the Questionnaire for Urinary Incontinence Diagnosis (QUID) were included. Results: In a cohort (n = 851) that was 62% Hispanic, we found a 63% point-prevalence rate for PLPP. Pregnant people who reported PLPP were further along in their pregnancy, did have significantly higher scores for the PMI and PGQ, indicating a greater level of disability, and reported issues with incontinence (QUID). Results of the logistic regression found that a higher PMI score and financial instability were factors influencing PLPP. Conclusions: In a cohort of majority Hispanic people, we found that 63% of respondents had PLPP. Our study found that a higher PMI score and financial instability were factors influencing PLPP. Clinicians should be alert to pregnant people who express their difficulties with activities of daily living as they may be at risk of PLPP, and could benefit from further evaluation and treatment.

Outcomes of a COVID-19 recovery program for patients hospitalized with SARS-CoV-2 infection in New York City: A prospective cohort study.

BACKGROUND: In the spring of 2020, New York City was an epicenter of coronavirus disease 2019 (COVID-19). The post-hospitalization needs of COVID-19 patients were not understood and no outpatient rehabilitation programs had been described. OBJECTIVE: To evaluate whether a virtual rehabilitation program would lead to improvements in strength and cardiopulmonary endurance when compared with no intervention in patients discharged home with persistent COVID-19 symptoms. DESIGN: Prospective cohort study. SETTING: Academic medical center. PATIENTS: Between April and July 2020, 106 patients discharged home with persistent COVID-19 symptoms were treated. Forty-four patients performed virtual physical therapy (VPT); 25 patients performed home physical therapy (HPT); 17 patients performed independent exercise program (IE); and 20 patients did not perform therapy. INTERVENTIONS: All patients were assessed by physiatry. VPT sessions were delivered via secure Health Insurance Portability and Accountability Act compliant telehealth platform 1-2 times/week. Patients were asked to follow up 2 weeks after initial evaluation. MAIN OUTCOME MEASURES: Primary study outcome measures were the change in lower body strength, measured by the 30-second sit-to-stand test; and the change in cardiopulmonary endurance, measured by the 2-minute step test. RESULTS: At the time of follow-up, 65% of patients in the VPT group and 88% of patients in the HPT group met the clinically meaningful difference for improvement in sit-to-stand scores, compared with 50% and 17% of those in the IE group and no-exercise group (P = .056). The clinically meaningful difference for improvement in the step test was met by 74% of patients in the VPT group and 50% of patients in the HPT, IE, and no-exercise groups (P = .12). CONCLUSIONS: Virtual outpatient rehabilitation for patients recovering from COVID-19 improved lower limb strength and cardiopulmonary endurance, and an HPT program improved lower limb strength. Virtual rehabilitation seems to be an efficacious method of treatment delivery for recovering COVID-19 patients.

Retained Fetal Bones: Rare cause of Abnormal Uterine Bleeding.

Intrauterine retention of fetal bones is a rare complication of unsafe abortion. Patients may present with infertility, chronic pelvic pain, menorrhagia and vaginal discharge. Here, we discuss a management of young female patient with uterine bleeding after miscarriage. Other causes of abnormal uterine bleeding such as infection, polyp, fibroid, malignancy were excluded. Retained intrauterine fetal bones were found as a sole cause of her complaint. Diagnosis was made with pelvic ultrasound and pelvic radiography. Dilatation and curettage was performed to remove the fetal bones with a good subsequent outcome.

Resident accuracy of joint line palpation using ultrasound verification.

OBJECTIVE: To determine the accuracy of knee and acromioclavicular (AC) joint line palpation in Physical Medicine and Rehabilitation (PM&R) residents using ultrasound (US) verification. DESIGN: Cohort study. SETTING: PM&R residency program at an academic institution. PARTICIPANTS: Twenty-four PM&R residents participating in a musculoskeletal US course (7 PGY-2, 8 PGY-3, and 9 PGY4 residents). METHODS: Twenty-four PM&R residents participating in an US course were asked to palpate the AC joint and lateral joint line of the knee in a female and male model before the start of the course. Once the presumed joint line was localized, the residents were asked to tape an 18-gauge, 1.5-inch, blunt-tip needle parallel to the joint line on the overlying skin. The accuracy of needle placement over the joint line was verified using US. MAIN OUTCOME MEASURES: US verification of correct needle placement over the joint line. RESULTS: Overall AC joint palpation accuracy was 16.7%, and knee lateral joint line palpation accuracy was 58.3%. Based on the resident level of education, using a value of P < .05, there were no statistically significant differences in the accuracy of joint line palpation. CONCLUSIONS: Residents in this study demonstrate poor accuracy of AC joint and lateral knee joint line identification by palpation, using US as the criterion standard for verification. There were no statistically significant differences in the accuracy rates of joint line palpation based on resident level of education. US may be a useful tool to use to advance the current methods of teaching the physical examination in medical education.

The muscle stretch reflex throughout the menstrual cycle.

INTRODUCTION: The significant sex disparity in sports-related knee injuries may be due to underlying differences in motor control. Although the development of sex-specific movement patterns is likely multifactorial, this study specifically focuses on the potential modulatory role of sex hormones. PURPOSE: This study aimed to investigate the muscle stretch reflex (MSR) across the menstrual cycle. We hypothesized that the MSR would fluctuate throughout the menstrual cycle and that the lowest response would correspond with peak concentrations of estrogen. METHODS: Nineteen healthy women age 18-35 yr participated in this study: 8 eumenorrheic women and 11 women taking oral contraceptives. Serum estradiol and progesterone concentrations, anterior knee laxity (AKL), and the MSR response of the quadriceps muscles were measured three times during the menstrual cycle. RESULTS: The MSR response of the rectus femoris (RF) varied significantly across the menstrual cycle in both groups. Specifically, the RF MSR response was 2.4 times lower during the periovulatory phase when compared with the luteal phase (P = 0.007). The same trend was seen in the vastus medialis, but this did not reach statistical significance (P = 0.070). The MSR response of the vastus lateralis did not change significantly across the menstrual cycle (P = 0.494). A mixed model comparison did not show an association between endogenous concentrations of estradiol and progesterone, exposure to hormonal contraceptives or AKL, and the MSR response for any muscle. CONCLUSIONS: Our results demonstrate that the RF MSR response varies throughout the menstrual cycle with the lowest response around the time of ovulation. Additional research is needed to clarify the exact relationship between sex hormones, AKL, and MSR response and to determine the specific origin of the change along the monosynaptic reflex arc.

Injectable medications for osteoarthritis.

Osteoarthritis is one of the most frequent and chronic conditions that affect the U.S. population. Use of intra-articular injections is one of the established treatment options available in the nonoperative care for the management of symptomatic osteoarthritis. Common injectable medications include corticosteroids, hyaluronic acid, and other less traditional compounds (for example, botulinum toxin). Corticosteroids work by anti-inflammatory and antinociceptive actions. Corticosteroids have been shown to decrease pain and symptoms associated with osteoarthritis for up to 3 weeks. Hyaluronic acid has an unclear mechanism of action, but it is thought to promote the restoration of hyaluronic acid within an osteoarthritic joint. The efficacy of hyaluronic acid is modest and is most beneficial between 5 and 13 weeks after treatment. Other injectable compounds have been studied and include botulinum toxin type A, which has been theorized to work as an antinociceptive agent. One must be aware of the potential adverse effects associated with these medications. For all of these injectable treatments, the placebo effect must not be overlooked, because it has be demonstrated in multiple studies that these medications provide similar relief of pain when compared with placebo. Image guidance with ultrasound or fluoroscopy may be considered when performing intra-articular injections to improve accurate placement of medication.

Prevalence of anatomic impediments to interlaminar lumbar epidural steroid injection.

OBJECTIVE: To determine the prevalence of anatomic impediments to interlaminar lumbar epidural steroid injection (LESI) in a community-based population. DESIGN: Cross-sectional observational study. SETTING: Community-based. PARTICIPANTS: Older adults (N=333) sampled irrespective of back pain status. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Computed tomography evaluation of 5 potential anatomic impediments to interlaminar LESI at the L2-S1 spinal levels, including (1) ligamentum flavum (LF) calcification, (2) interspinous ligament (ISL) calcification, (3) spinous process (SP) contact, (4) the absence of epidural fat in the posterior epidural space, and (5) the presence of fat density superficial to the LF in the midsagittal plane. Independent variables included age, sex, body mass index (BMI), and current smoking. RESULTS: LF and ISL calcifications were prevalent in 3% to 7% and 2% to 3% of spinal levels, respectively, without significant differences by spinal level. SP contact was most common at the L4-5 level (22%). Absence of posterior epidural fat was very common at L5-S1 (65%), but infrequent at other levels. The presence of midline fat density superficial to LF was most common at L5-S1 (55%). The prevalence of LF calcification, ISL calcification, and SP contact increased with age, but the prevalence of absence of posterior epidural fat and the presence of a midline fat density superficial to LF did not. Sex and smoking status were not associated with the prevalence of anatomic impediments, but higher BMI was associated with a lower prevalence of absence of posterior epidural fat. CONCLUSIONS: Anatomic impediments to interlaminar LESI were common in this community-based population, particularly at the L5-S1 spinal level. Because of the high overall prevalence of anatomic impediments, and differences in prevalence by spinal level, knowledge of the distribution and frequency of these impediments may aid in aspects of decision-making for the interventional spine physician.
