Lumbar Extension PPIVMs

Physical Therapy First demonstration of Lumbar Extension PPIVMs What you’ll see A demonstration of Lumbar Extension PPIVMs (Passive Physiological Intervertebral Movements) used to assess segmental mobility and symptom response during lumbar extension. The video shows how a clinician positions the patient, stabilizes the pelvis and adjacent segments, and passively guides the lumbar spine into extension in a controlled, level-by-level manner to evaluate motion quality, end-feel, and whether symptoms are reproduced or relieved. Setup • Patient is positioned comfortably as shown (commonly side-lying or prone depending on the technique demonstrated). • Clinician explains the purpose of the test and asks the patient to report: Local low back pain vs. referred symptoms Any sharp pain, numbness/tingling, or symptom changes into the buttock/leg • Clinician identifies landmarks: Lumbar spinous processes/interspinous spaces Pelvic landmarks to orient lower lumbar segments (L4–L5, L5–S1) • Patient is cued to relax the trunk and hips and breathe normally to reduce guarding. • Clinician positions hands/forearms to stabilize the pelvis and control lumbar motion. Movement 1) Segment identification and starting position • Clinician locates the target lumbar level and establishes a stable contact. • Pelvis is stabilized to limit hip compensation and isolate lumbar motion. 2) Passive lumbar extension (PPIVM assessment) • Clinician passively guides the lumbar spine into extension using small, controlled movements. • Motion is localized by stabilizing one segment while moving the segment above/below (as demonstrated). • The clinician assesses: Available extension at each level Quality and smoothness of motion End-feel (firm, stiff, guarded, painful) Symptom response (reproduction, reduction, centralization/peripheralization) 3) Level-by-level comparison • The assessment is repeated across adjacent lumbar segments to map restrictions or sensitive levels. • Clinician notes whether symptoms are segment-specific or more global. 4) Reassessment and clinical correlation • Findings are correlated with active extension testing, neurological screen, and functional tolerance (standing, walking, prone press-ups, etc.). • Results help guide treatment decisions (mobilization/manipulation, stabilization, directional preference exercise). Coaching cues • “Let your body relax and be heavy.” • “Tell me if this feels stiff, pinchy, sharp, or reproduces your symptoms.” • “Let me know if symptoms travel into the leg or move back toward the spine.” • “Breathe normally—don’t brace or hold your breath.” Why it helps • Identifies lumbar segments that are stiff, painful, or guarded in extension. • Helps differentiate segmental restriction from hip or soft tissue limitations. • Guides manual therapy and exercise selection (extension tolerance vs. sensitivity, stability needs). • Provides baseline findings to track mobility and symptom changes over time. Dosage (general guideline) • Performed as a brief assessment at each level with frequent symptom check-ins. • Force is low and graded based on irritability and patient response. • Always interpreted within the full evaluation (history, ROM, neuro screen, red flags). Common errors (clinical considerations) • Poor pelvic stabilization allowing hip motion to substitute for lumbar extension. • Using excessive force or moving too quickly, increasing guarding. • Not comparing multiple levels for pattern recognition. • Over-interpreting tenderness without correlating to symptom behavior and functional tests. • Continuing despite progressive neurological symptoms or significant symptom worsening.

Lumbar PPIVM assessment should be performed and interpreted by appropriately trained clinicians as part of a comprehensive evaluation. Seek urgent medical care for bowel/bladder changes, saddle anesthesia, severe or progressive weakness, significant trauma, unexplained fever, or rapidly worsening symptoms. https://physicaltherapyfirst.com
