Hint : 🧠 UMN = spastic bladder, not flaccid

Correct Answers:

  • spastic, involuntary voiding


Rationale :

🧠 Upper motor neuron (UMN) injuries, such as those occurring above the sacral micturition center (typically above T12), result in a spastic neurogenic bladder.

🧠 In this condition, the detrusor muscle contracts involuntarily, and the patient experiences reflexive, uncontrolled bladder emptying (spastic voiding).

🧠 Although the spinal reflex arc is intact, the brain's voluntary control over voiding is lost, leading to incontinence and urgency.

🧠 This contrasts with lower motor neuron injuries (below T12), where the bladder becomes flaccid and areflexic, resulting in retention or overflow incontinence.

🧠 Nursing care focuses on scheduled voiding or intermittent catheterization and bladder retraining to manage incontinence and prevent complications like UTIs or autonomic dysreflexia.
