OCS2 – GI & Lumbar OMM Exam Q&A | 75+ Verified Answers | Abdominal Exam, Facet Mechanics, Counterstrain, Muscle Energy | 2025/2026

This document presents 75+ graded and verified exam-style questions and answers from the OCS2 (Objective Clinical Skills – Week 28 CS & OMM/CSA) module at Medical University, tailored for the 2025/2026 academic year. It combines clinically applied abdominal physical exam techniques with osteopathic assessment of the thoracic and lumbar spine, including muscle energy, counterstrain, and facet diagnosis. The material is ideal for OSCE prep, OMM check-offs, and integrated clinical exams. Topics covered include: Abdominal Clinical Exam: Step-by-step coverage of inspection, auscultation (including 7 arterial bruits: renal, aortic, iliac), percussion (liver span, spleen, gastric bubble), and palpation (organ size, aorta, hernias, Murphy's punch). Viscero-somatic Reflexes: Assessment of nodular ganglia down the linea alba (celiac, superior and inferior mesenteric), and palpatory methods for liver and kidney sensitivity linked to internal pathology. Facet Mechanics (Thoracic & Lumbar): In-depth application of Fryette’s Laws, interpretation of spinal segment diagnosis (e.g., L2 FSR right → left facet open), and rules of closed vs. open facets in flexion vs. extension. Muscle Energy (ME): Protocols for treating Type II lumbar dysfunctions in flexed, extended, and bilateral patterns. Mnemonics like BITE for rib dysfunctions are also included. Counterstrain (CS): Treatment positions and indications for both thoracic and lumbar anterior/posterior tender points, including rib dysfunctions and how to position for SARA, STRA techniques. OMM Integration with Clinical Findings: Students learn to interpret palpatory findings (e.g., prominent transverse processes, spinous process spacing) to assign correct somatic dysfunction names and treatment approaches. This document is perfect for: DO and MD students preparing for OMM practicals, clinical skills exams, or OCS/CSA midterms Learners in OMM-intensive programs or those pursuing board certification with osteopathic focus PA, PT, and Chiropractic students who need a working understanding of lumbar and GI physical exams Keywords: abdominal exam, OMM, muscle energy, counterstrain, Fryette's laws, facet diagnosis, lumbar spine, thoracic spine, viscerosomatic reflexes, bruits, Murphy’s punch, rib dysfunction, tender point treatment, GI physical exam, somatic dysfunction, palpatory diagnosis, spinal mechanics
