Challenges and Research Opportunities for Integrating Quantitative Electroencephalography Into Sports Concussion Rehabilitation.

Although concussion management and return to play/learn decision making focuses on reducing symptoms, there is growing interest in objective physiological approaches to treatment. Clinical and technological advancements have aided concussion management; however, the scientific study of the neurophysiology of concussion has not translated into its standard of care. This expert commentary is motivated by novel clinical applications of electroencephalographic-based neurofeedback approaches (eg, quantitative electroencephalography [QEEG]) for treating traumatic brain injury and emerging research interest in its translation for treating concussion.

Post-concussion changes in the N200 and P300 ERPs are associated with cognitive symptoms and performance.

Purpose: To examine how post-concussion changes to the N200 and P300 event-related potentials (ERPs) are associated with cognitive symptoms and neurocognitive performance.

Methods: High-density electroencephalography (EEG) was recorded during a Go/No-Go task from 16 young adults within one month after their concussion and 16 matched controls. Participants were also administered the Cognitive-Linguistic Quick Test (CLQT) and self-reported concussion-like symptoms.

Calcific tendinitis of gluteus maximus insertion.

Calcific tendinitis, classified as enthesopathy, is a self-limiting disease that rarely involves the tendons of the gluteus maximus. We discuss a 52-year-old woman with a 1-year history of localized, reproducible posterolateral pain of her left hip, which was previously treated with steroid injection to her left greater trochanteric bursa without significant pain relief. Plain radiography and magnetic resonance imaging of the left hip revealed abnormal edema and calcifications at the insertion of the gluteus maximus tendon to the gluteal tuberosity, corresponding to the area of maximal tenderness on examination.

Association between days for concussion recovery and initial specialty clinic evaluation within 48 hours.

Background: Researchers have highlighted the importance of early access to concussion care within one week of injury in reducing recovery times. However, a persisting question for concussion researchers is "just how early is important?" The purpose of this study was to examine differences in recovery time as predicted by the number of days elapsed since injury (DSI) to initial evaluation among patients who had access to a specialty concussion clinic within seven days. We hypothesized that DSI group membership, even within seven days, would significantly predict risk of protracted recovery (i.

The Utility of Myotonometry in Musculoskeletal Rehabilitation and Human Performance Programming.

Myotonometry is a relatively novel method used to quantify the biomechanical and viscoelastic properties (stiffness, compliance, tone, elasticity, creep, and mechanical relaxation) of palpable musculotendinous structures with portable mechanical devices called myotonometers. Myotonometers obtain these measures by recording the magnitude of radial tissue deformation that occurs in response to the amount of force that is perpendicularly applied to the tissue through a device's probe. Myotonometric parameters such as stiffness and compliance have repeatedly demonstrated strong correlations with force production and muscle activation.

Gender Differences and the Influence of Body Composition on Land and Pool-Based Assessments of Anaerobic Power and Capacity.

Consistent differences between males and females have been shown in land-based measurements of anaerobic power and capacity. However, these differences have not been investigated for a tethered 30-s maximal swimming test (TST). The purpose of this study is to explore gender differences in land and pool-based assessments of anaerobic power (Fpeak) and capacity (Fmean), as well as the influence of body composition.

Chondrogenesis with Autologous Peripheral Blood Stem Cells for End-Stage Ankle Arthritis: Report of Three Cases.

End-stage ankle arthritis represents an "unmet medical need", awaiting an appropriate time for joint arthroplasty or arthrodesis. We report three cases of end-stage ankle arthritis treated along the principles developed for chondrogenesis of the knee joint with autologous peripheral blood stem cells, resulting in reversal of the ankle arthritis. The improvement in clinical outcome measure scores (Ankle Osteoarthritis Scale total score) with a minimum two-year follow-up were comparable to total ankle replacement (TAR), arthroscopic ankle arthrodesis (AAA) and open ankle arthrodesis (OAA).
