      The use of ultrasound (US) to perform quantitative measurements of musculoskeletal tissues requires accurate and reliable measurements between investigators and ultrasound machines. The objective of this study was to evaluate inter-rater and intra-rater reliability of patellar tendon measurements between providers with different levels of US experience and inter-machine reliability of US machines. Sixteen subjects without a history of knee pain were evaluated with US examinations of the ...

      BACKGROUND CONTEXT: The timing of physical therapy (PT) services and its association with later function and pain are not clear, especially in older adults.

      PURPOSE: The purpose of this study was to compare clinical outcomes of patients receiving early or later PT services with those not receiving PT among older adults presenting to primary care for a new visit for back pain.

      STUDY DESIGN/SETTING: Prospective cohort study using the Back Pain Outcomes Using Longitudinal Data ...

      STUDY DESIGN: Systematic review.

      BACKGROUND: Current US practice guidelines suggest an initial "wait-and-see" approach following onset of musculoskeletal pain, particularly for spinal pain. Several studies suggest that early, compared with delayed, initiation of physical therapy for musculoskeletal conditions may decrease health costs and improve outcomes.

      OBJECTIVE: To compare early and delayed initiation of physical therapy for individuals with musculoskeletal conditions and to assess ...

      OBJECTIVE: To determine whether lumbar muscle characteristics on magnetic resonance imaging (MRI) or computed tomography (CT) can inform clinicians as to the course of future low back pain (LBP), functional limitations, or physical performance, in adults with or without LBP. TYPE: Systematic review.

      LITERATURE REVIEW: We searched PubMed, Embase, and CINAHL through October 2014 for articles published in English in which authors assessed lumbar muscle characteristics on conventional MRI/CT ...

      BACKGROUND: The association between early physical therapy (PT) and subsequent health-care utilization following a new visit for low back pain is not clear, particularly in the setting of acute low back pain.

      PURPOSE: This study aimed to estimate the association between initiating early PT following a new visit for an episode of low back pain and subsequent back pain-specific health-care utilization in older adults.

      DESIGN/SETTING: This is a prospective cohort study. Data were collected ...

      STUDY DESIGN: Retrospective cohort study.

      OBJECTIVE: To evaluate the relationship between early physical therapy (PT) for acute low back pain and subsequent use of lumbosacral injections, lumbar surgery, and frequent physician office visits for low back pain.

      SUMMARY OF BACKGROUND DATA: Wide practice variations exist in the treatment of acute low back pain. PT has been advocated as an effective treatment in this setting although disagreement exists regarding its purported ...

      OBJECTIVE: Knee osteoarthritis (OA) has a significant impact on quality of life (QOL). Although QOL is generally thought to diminish over time, it is unknown whether different patient groups demonstrate unique patterns of change in QOL. We sought to identify and characterize QOL trajectories in knee OA.

      DESIGN: This prospective cohort study included 1013 individuals with symptomatic knee OA from the osteoarthritis initiative. We used group-based trajectory modeling to identify distinct ...

      Obtaining accurate and readily repeatable measurements is a prerequisite for using measures of soft tissue structures both clinically and in the research setting. Few studies have evaluated the interrater reliability of ultrasound measurements of tendons. The objective of this study was to determine the accuracy and reliability of a new method of sonographic measurement of patellar tendon length using direct dissection as the gold standard. Four cadaveric knees were sonographically ...

      Primary disabling conditions, such as amputation, not only limit mobility, but also predispose individuals to secondary musculoskeletal impairments, such as osteoarthritis (OA) of the intact limb joints, that can result in additive disability. Altered gait biomechanics that cause increased loading of the intact limb have been suggested as a cause of the increased prevalence of intact limb knee and hip osteoarthritis in this population. Optimizing socket fit and prosthetic alignment, as ...

      Spinal osteoarthritis primarily manifests as disease of the facet joints of the posterior spine. This Review presents the latest information about the prevalence, presentation, and nature of facet joint osteoarthritis, an important cause of spinal pain that should be viewed as failure of the whole joint rather than a disease of articular cartilage loss and bony hypertrophy.

      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 ...

      The objective of this preliminary study was to evaluate the ability of individual 0.1-s long pulses of intense focused ultrasound (iFU) emitted with a carrier frequency of 2 MHz to evoke diagnostic sensations when applied to patients whose shoulders have rotator cuff tears or tendinopathy. Patients were adults with painful shoulders and clinical and imaging findings consistent with rotator cuff disease. iFU stimulation of the shoulder was performed using B-mode ultrasound coupled with a ...

      BACKGROUND: Platelet-rich plasma (PRP) is a minimally invasive treatment option to reduce pain and promote tissue healing. At the time this study was performed, there was limited published literature analyzing outcomes for patients treated with PRP for hip osteoarthritis.

      METHODS: Thirty-six patients aged 49-85 (66.0 ± 12.1) years with chronic hip pain who met inclusion criteria underwent image-guided intra-articular hip PRP injection. Outcomes were measured at baseline, two weeks, three ...

      BACKGROUND: Minimal longitudinal data exist regarding the role of lumbar musculature in predicting back pain and function. In cross-sectional study designs, there is often atrophy of the segmental multifidus muscle in subjects with low back pain compared with matched controls. However, the cross-sectional design of these studies prevents drawing conclusions regarding whether lumbar muscle characteristics predict or modify future back pain or function.

      OBJECTIVE: The primary objective of ...

      The current COVID‐19 pandemic has rapidly affected a large number of people across the world. In the US, New York and Massachusetts were two states significantly affected early on in the pandemic. Many individuals infected with COVID‐19 require hospitalization and following discharge, a subset develop longer‐term rehabilitation needs. To address the ongoing rehabilitation needs in this growing population, multidisciplinary teams at academic centers in NYC and Boston designed and ...
