Assessing Physical Medicine and Rehabilitation Residency Education Using the Neurological Assessment Competency Evaluation System.

ABSTRACT: Competent neurologic examination and clinical skills are essential components in the care for patients in acute hospital and rehabilitation settings. To enhance the evaluation and education of Physical Medicine and Rehabilitation residents, the authors developed an educational objective structured clinical examination, the Neurological Exam Assessment Competency Evaluation System, and gathered 2 yrs of baseline data. The Neurological Exam Assessment Competency Evaluation System consisted of nine 9-min examination stations, seven with written clinical scenario with instructions for junior residents to complete the appropriate examination (stations: Altered Mental Status, Mild Traumatic Brain Injury, Dementia, Stroke, Falls, and the International Standards for Neurological Classification of Spinal Cord Injury Sensory and Motor Examinations). Examinees provided written responses to posed questions for the other two stations-Modified Ashworth Scale and brachial plexus. The assessment tools for this examination were designed for residency programs to evaluate the basic competencies as outlined by the Accreditation Council for Graduate Medical Education and Physical Medicine and Rehabilitation milestones. Based on the feedback received from the examinees and examiners, the Neurological Exam Assessment Competency Evaluation System can serve as an educational objective structured clinical examination for the improvement of trainee core competencies.

Leukocyte-rich platelet-rich plasma application in post-traumatic osteoarthritis with popliteal cyst: a case report.

Aim: To describe the successful treatment of a Baker's cyst in the setting of post-traumatic osteoarthritis using ultrasound-guided injection of platelet-rich plasma. Setting: Outpatient sports clinic. Patient: 29-year old male basketball player. Case description: The patient presented with 2-months history of right knee pain, 17 months after undergoing right knee anterior cruciate ligament reconstruction surgery. Exam revealed medial joint line and medial collateral ligament tenderness with posterior knee swelling. After aspiration, a corticosteroid injection was administered with temporary symptom relief. Diagnostic ultrasound examination confirmed the Baker's cyst. The patient then underwent two serial leukocyte-rich platelet-rich plasma injections into his right knee. Results: The patient reported complete resolution of pain and cyst size. Conclusion: Leukocyte-rich platelet-rich plasma may be considered as a treatment option for patients with Baker's cysts in the setting of post-traumatic osteoarthritis.

Effects of Antiplatelet and Nonsteroidal Anti-inflammatory Medications on Platelet-Rich Plasma: A Systematic Review.

BACKGROUND: Platelet-rich plasma (PRP) has wide applications in orthopaedic care. Its beneficial effects are attributed to the growth factor profile from the platelet secretome. In theory, these effects would be diminished by medications that inhibit platelet activation and/or the subsequent release of growth factors. PURPOSE: To determine whether commonly used antiplatelets, nonsteroidal anti-inflammatory drugs (NSAIDs), or anticoagulant medications affect platelet growth factor release in PRP. STUDY DESIGN: Systematic review; Level of evidence, 2. METHOD: A systematic review of the literature related to antiplatelet, anti-inflammatory, and anticoagulant drugs was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We used the Downs and Black objective quality scoring system. The literature search consisted of PubMed and Cochrane Library databases. Search terms consisted of 1 item selected from "platelet-rich plasma," "platelet-derived growth factor," and "platelet-rich plasma AND growth factor" combined with 1 item from "antiplatelet," "aspirin," "anticoagulant," and "NSAID." Only studies published within the past 25 years were included. RESULTS: A total of 15 studies met the inclusion criteria: 7 studies detected no significant decrease in growth factors or mitogenesis, whereas 6 detected a decrease with antiplatelet agents, 1 detected mixed results with an antiplatelet agent, and 1 had mixed results with an antiplatelet agent/vasodilator. In terms of PRP activation, all 3 studies assessing collagen, the 2 studies analyzing adenosine diphosphate alone, and the 1 study investigating arachidonic acid found a decrease in growth factor concentration. CONCLUSION: Antiplatelet medications may decrease the growth factor release profile in a cyclooxygenase 1- and cyclooxygenase 2-dependent manner. Eight of 15 studies found a decrease in growth factors or mitogenesis. However, more studies are needed to comprehensively understand antiplatelet effects on the PRP secretome.
