Harding ataxia


A rare neurological disorder primarily involving poor balance and coordination while tendon reflexes are not affected.


* Poor balance * Poor coordination


Prepare the patient for diagnostic tests to evaluate hyperactive DTRs, such as laboratory tests for serum calcium, magnesium, and ammonia levels; spinal X-rays; magnetic resonance imaging; a computed tomography scan; lumbar puncture; and myelography. ▪ If motor weakness accompanies hyperactive DTRs, perform or encourage range-of-motion exercises to preserve muscle integrity and prevent deep vein thrombosis. ▪ Reposition the patient frequently, supply a special mattress, provide skin care, and ensure adequate nutrition to prevent skin breakdown. ▪ Administer a muscle relaxant and sedative to relieve severe muscle contractions. ▪ Keep emergency resuscitation equipment on hand. ▪ Provide a quiet, calm atmosphere to decrease neuromuscular excitability. ▪ Assist with activities of daily living, and provide emotional support.
