Differentiate faster, screen safer, and collaborate smarter. Differentiating Systemic and Musculoskeletal Pain Patterns for PTAs is a practical, case-driven course designed to help Physical Therapist Assistants recognize when pain points to a musculoskeletal origin—and when it signals potential systemic or viscerogenic involvement that warrants referral. You’ll translate foundational pain science into daily decision-making, using clear frameworks for location, description, pattern, aggravating/relieving factors, and associated symptoms. Then, you’ll apply those frameworks to real-world scenarios to improve clinical efficiency and patient safety. Inside, you will unpack mechanisms of referred visceral pain, multisegmental innervation, and shared neural pathways so you can make sense of confusing presentations. Compare systemic versus musculoskeletal pain patterns side-by-side, learn common referral maps, and spot red flags quickly. Whether you’re in outpatient orthopedics, home health, inpatient rehab, or sports, this course gives you repeatable tools to communicate findings to the PT, advocate for the patient, and choose the right interventions at the right time. By the end, you’ll confidently distinguish local tissue dysfunction from system-driven symptoms, streamline progress notes and handoffs, and elevate your role on the care team.

            <p>Physical Therapist Assistants play a critical role in the clinical environment by monitoring patient progress and identifying symptoms that may fall outside the scope of traditional musculoskeletal rehabilitation. Understanding the nuances between systemic and musculoskeletal pain is essential for ensuring patient safety and facilitating appropriate medical referrals. This course delves into the physiological mechanisms of referred visceral pain, exploring how multisegmental innervation and shared neural pathways can cause internal organ dysfunction to manifest as orthopedic discomfort. By mastering these concepts, PTAs can better recognize when a patient's presentation requires a consultation with the supervising Physical Therapist or further medical screening.</p>

<p>Throughout this curriculum, participants will examine the specific characteristics that define various pain patterns, including the location, description, and aggravating or relieving factors of symptoms. Detailed modules will cover the differences between somatic and visceral sources of pain, as well as clinical red flags such as night pain and pain at rest. By comparing systemic versus musculoskeletal patterns and studying common referral maps, clinicians will gain the tools necessary to differentiate myofascial and joint issues from more serious viscerogenic conditions. This comprehensive approach ensures that every PTA is equipped to provide high-quality care while remaining vigilant for signs of systemic pathology.</p>
